Description

{GAS STATION PIPING INSTALLATION STRUCTURE}

Embodiments of the present invention relate to a gas station piping installation structure.

As is well known, most existing gas stations are constructed by burying hazardous material pipes (e.g., fuel pipes, underfloor heating pipes, vent pipes, vapor recovery pipes, etc.) (hereinafter referred to as “pipes”) underground.

For this reason, the pipes of gas stations are buried underground, and after construction, they are structured in a way that makes it difficult to visually observe or inspect the buried pipes.

However, if a long period of time passes after the pipes are buried underground and constructed, serious damage to the pipes, such as twisting deformation or corrosion of the pipes, may occur depending on external conditions such as various external forces and the environment.

If a pipe is damaged, oil may flow out of the damaged pipe, and the oil leaked from the pipe may contaminate the soil. As a result, a lot of money had to be spent on remediation work to clean up the soil contaminated by the oil.

In this way, it is important to inspect the gas station pipes in advance to check for damage in advance, and to not miss the time for pipe replacement through this pipe inspection. However, if the gas station pipes are buried underground in the conventional way, it is difficult to inspect the condition of the buried pipes, and there is a problem that it is easy to miss the time for pipe replacement.

Therefore, in the gas station pipe installation structure, there is a need for structural improvement so that preliminary inspection of the pipes can be easily performed even after construction, and pipe replacement work can be easily performed without missing the pipe replacement period.

In particular, there is a need for technology development that allows gas station pipes to be centralized within a certain structure so that the pipes can be visually inspected for damage at any time without digging the ground, and pipe replacement work can be performed in a timely manner.

In addition, there is a need to develop a technology that can prevent soil contamination in advance by using a separate collection means to collect oil leaking from the pipe in the event of an oil leak.

As a prior art related to the present invention, there is Korean Patent Application No. 10-2014-0135811 (hereinafter, “prior document”), and the prior document discloses a technology regarding a gas station pipe monitoring system.

However, the prior art documents disclosed herein only present a method of judging whether there is an abnormality in the fuel supply pipe by using a sensor that detects the pressure and temperature of the pipe, and providing the presence or absence of an abnormality in the pipe to the central monitoring team. In other words, the prior art documents do not present any structure in which the pipes are centrally placed within the pit so that they can be visually confirmed.

Republic of Korea Patent Application No. 10-2014-0135811

The purpose of the present invention is to provide a gas station pipe installation structure in which the pipe can be easily replaced without missing the pipe replacement period by making it easy to visually inspect the pipe through a cover even after the pipe has been constructed.

Another object of the present invention is to provide a gas station pipe installation structure capable of centrally arranging the pipes of a gas station so that they are exposed on the ground by forming a pit (i.e., a box-shaped concrete structure with an open top) equipped with a predetermined pipe installation conduit under a gas station installation surface where a gas station is installed.

Another object of the present invention is to provide a gas station pipe installation structure capable of preventing soil contamination due to oil spills in advance by allowing oil to be collected using a collecting device even when oil spills occur from the pipes.

The purposes of the present invention are not limited to the purposes mentioned above, and other purposes and advantages of the present invention which are not mentioned can be understood by the following description, and will be more clearly understood by the embodiments of the present invention. In addition, it will be easily understood that the purposes and advantages of the present invention can be realized by the means and combinations thereof indicated in the claims.

In order to achieve the above object, a gas station pipe installation structure according to one embodiment of the present invention comprises: a pit formed below a gas station installation surface on which at least one gas pump is installed, the pit having an open upper portion and having a pipe installation conduit therein; a pipe installed along the pipe installation conduit within the pit; and a cover openably and closably coupled to the open upper portion of the pit, the cover exposing the pipe installed in the pipe installation conduit above the ground to enable replacement of the pipe.

In a gas station pipe installation structure according to one embodiment of the present invention, the cover may have a detachable structure that is coupled to cover the upper part of the pit or is detachable from the upper part of the pit.

In addition, in a gas station pipe installation structure according to one embodiment of the present invention, the cover includes a cover body having a size corresponding to the open upper portion of the pit; and a hole formed in the cover body.

Here, the hole can be formed by penetrating the cover body in the thickness direction. The hole can enable inspection of the pipe installed in the pipe installation conduit without separating the cover body while the cover body is connected to the upper part of the pit.

In addition, in the gas station pipe installation structure according to one embodiment of the present invention, the cover may be a grating member having a size corresponding to the open upper portion of the pit and having a plurality of holes formed in a lattice structure. The grating member is a cover member having holes in a lattice structure that allow drainage, and has sufficient rigidity to protect the pipes placed in the pit from the ground, and has an advantage in that a plurality of holes are provided so that a worker can visually inspect the pipe condition at all times. However, a cover having a structure without holes, i.e. a closed structure, may be installed in a location where people pass by frequently.

In a gas station pipe installation structure according to one embodiment of the present invention, the pit includes a base portion made of concrete that is formed horizontally at a set depth from the open upper portion and forms a sealed lower surface of the pipe installation conduit; and side portions that are formed extending from both sides of the base portion to the height of the fuel pump installation surface and form sealed both side wall surfaces of the pipe installation conduit, and are made of concrete.

In addition, in the gas station pipe installation structure according to one embodiment of the present invention, the pit may be located below the fuel pump installation surface, and the open width size of the pit may be formed smaller than the width size of the fuel pump. Accordingly, stable installation of the fuel pump installed on the open upper part of the pit is possible, and there is an advantage in securing the rigidity of the structure while sufficiently connecting the necessary number of pipes to the inside of the pit.

In addition, in the gas station pipe installation structure according to one embodiment of the present invention, the pit further includes a pipe support member that supports the pipe inside the pipe installation conduit. The pipe support member has one end fixed to the base member, and the other end protrudes from the base member to a set height, and can support the pipe horizontally by lifting it from the base member to the set height.

In addition, a gas station pipe installation structure according to one embodiment of the present invention further includes a fuel collecting device that collects fuel that has flowed out from the pipe into the interior of the pipe installation conduit. Preferably, the fuel collecting device includes: a water collecting unit having a collecting space that collects water collected through the cover or fuel that has flowed out from the pipe; a water transfer line that transfers the collected water to the water collecting unit; and an oil/water separator that receives the water from the water transfer line and separates the water.

Preferably, the water collection unit can be connected to at least one end of the pit so as to be connected to the pipe for installation of the pipe.

In addition, the water collection unit is provided with a water collection space having a predetermined size to collect the water or the oil, and the water collection space can be formed at a lower position than the base. Preferably, the upper height of the water collection space can be formed to be the same as or lower than the height of the base. Accordingly, the water collected in the base can flow smoothly into the water collection space.

Preferably, the collecting device includes: a pump connected to the water transfer line and flowing the water collected in the water collection unit through the water transfer line; a controller controlling the operation of the pump; and at least one sensor installed in the water collection unit and detecting the water level of the water collected in the water collection unit. The controller controls the operation of the pump based on the water level information detected by the at least one sensor. A plurality of sensors may be provided, and the plurality of sensors may be positioned at different heights within the water collection unit. The plurality of sensors positioned at different heights individually detect the water level of the water at different heights, thereby enabling the operation of the pump using the controller to be controlled more precisely.

In addition, the gas station pipe installation structure according to one embodiment of the present invention further includes at least one oil vapor detection sensor installed in the pit and detecting oil vapor at a location adjacent to the pipe. The oil vapor detection sensor detects oil vapor components diffused around the pipe, thereby enabling real-time detection of oil leakage. In addition, when oil vapor generated at the gas station accumulates in the pit due to its characteristic of being heavier than air, it detects it in real-time, thereby enabling rapid ventilation work.

In addition, in a gas station pipe installation structure according to one embodiment of the present invention, the pipe includes at least one of a fuel pipe, a lowering pipe, a vent pipe, and a vapor recovery pipe.

According to an embodiment of the present invention, even after construction of the pipe, preliminary inspection of the pipe is possible with the naked eye through a hole in the cover, so that pipe replacement can be easily performed without missing the pipe replacement period.

In addition, according to an embodiment of the present invention, a pit (i.e., a box-shaped concrete structure with an open top) having a predetermined pipe installation conduit is formed under a surface where a fuel pump is installed, and the pipes of the gas station can be centrally arranged inside the pipe installation conduit, so that the convenience of inspection and replacement of the pipes can be greatly improved.

In addition, according to an embodiment of the present invention, even if an oil leak occurs from a pipe, the oil can be collected using an oil collecting device, and soil contamination due to the oil leak can be prevented in advance.

[Overall structure of gas station pipe installation structure]

A gas station pipe installation structure (1) according to one embodiment of the present invention includes a pit (20), a pipe (40), a cover (50), and a fuel collecting device (70).

A pit (20) can be formed under a fuel tank installation surface (11) on which at least one fuel tank (10) is installed.

Here, the number and type of the fuel pumps (10) may be determined differently depending on the gas station. For example, referring to Fig. 1, a structure in which four fuel pumps (10) are installed is shown, but the present invention is not limited to the illustrated form, and the number and type of the fuel pumps (10) may be changed without limitation.

The pit (20) is a concrete structure formed at the bottom of the fuel tank installation surface (11) on which at least one fuel tank (10) is installed, and the upper part (21) is open, and the remaining surfaces except for the open upper part (21), for example, the lower part and both sides, may have a box-shaped structure that is closed.

A pipe installation conduit (30) having a square cross-section can be formed inside the pit (20). A plurality of pipes used in a gas station can be installed so that they are exposed on the ground through the pipe installation conduit (30). In addition, the pipes installed through the pit (20) can be connected to an underground tank (3) (see FIG. 1).

The pipe (40) can be installed along the pipe installation conduit (30) within the pit (20). The pipe (40) that can be installed and used along the pipe installation conduit (30) within the pit (30) can be a hazardous material pipe of a gas station. For example, the hazardous material pipe can include a fueling pipe, a lowering pipe, a vent pipe, and a vapor recovery pipe, and in addition, a number of other pipes that are necessary can be included.

The cover (50) refers to a cover member that is openably and closably connected to the open upper part (21) of the pit (20).

The cover (50) is connected to cover the open upper part (21) of the pit (20), and protects the pipe (40) installed in the pipe installation conduit (30) from the outside, but since it has a plurality of holes (52), the pipe (40) installed in the pipe installation conduit (30) can be exposed to the ground (11). Accordingly, even when the cover (50) is covered, the worker can visually inspect the pipe (40) at any time, and can easily check for damage and aging of the pipe (40). In addition, the cover (50) has a detachable structure, so that the cover (50) can be separated to easily replace and install damaged or aging pipe (40).

In addition, the gas station pipe installation structure (1) according to one embodiment of the present invention further includes a fuel collecting device (70). The fuel collecting device (70) is configured to collect fuel that has flowed from the pipe (40) into the interior of the pipe installation conduit (30).

Hereinafter, the detailed configuration of the pit (20), cover (50), and fuel collecting device (70) included in the gas station pipe installation structure (1) according to one embodiment of the present invention will be described in detail with reference to the attached drawings.

[feet]

In a gas station pipe installation structure (1) according to one embodiment of the present invention, a pit (20) is formed on the ground where a gas pump (10) is installed, i.e., below the gas pump installation surface (11).

As one embodiment of the present invention, the pit (20) may be a box-shaped concrete structure with an open upper portion (21).

A cover (50) can be attached to cover the open upper part (21) of the pit (20).

In addition, a square cross-section pipe installation conduit (30) can be formed inside the pit (20). Through the pipe installation conduit (30), a number of pipes used in a gas station can be installed so that they are exposed on the ground.

The number and type of fuel pumps (10) can be used in various ways. Referring to Fig. 1, four fuel pumps (10) are shown installed on the ground, that is, above the fuel pump installation surface (110). The present invention is not limited to the form shown in Fig. 1, and the number and type of fuel pumps (10) can be changed and used without limitation.

Specifically, as one embodiment of the present invention, the pit (20) includes an open upper portion (21), a base portion (22), and a side portion (23).

The upper part (21) of the pit (20) is open so that a cover (50) can be covered and joined.

The base part (22) is formed horizontally at a set depth in the open upper part (21) and can form a sealed lower surface of the pipe installation conduit (30) in which the pipe (40) is installed. The base part (22) can have a concrete material.

The side section (23) is a side wall portion formed by extending from both sides of the base section (22) to the fuel tank installation surface (11), i.e., ground level, and forms a sealed side wall surface of a pipe installation conduit (30) in which a pipe (40) is installed. The side section (23) may have a concrete material.

In addition, as an embodiment of the present invention, the pit (20) is located on the ground where the fuel pump (10) is installed, that is, below the fuel pump installation surface (11), and preferably, the open width size of the pit (20) can be formed smaller than the width size of the fuel pump (10) (see FIG. 2). Accordingly, the fuel pump (10) can be installed more stably above the open upper portion (21) of the pit (20), and a plurality of pipes (40) can be stably arranged through the pipe installation conduit (30) provided inside the pit (20), so that there are various advantages in terms of structural design and securing rigidity.

In addition, as one embodiment of the present invention, the pit (20) further includes a pipe support (60).

The pipe support (60) is installed so as to stand upright on the inner floor of the pipe installation conduit (30) and supports the pipe (40) by a certain height from the base (22). Accordingly, various pipe damages and problems, such as contamination and corrosion, that may occur when the pipe (40) touches the base (22) can be prevented in advance.

For example, the pipe support (60) may have a support shape in which one end (i.e., the lower end) is fixed to the base (22), and the other end (i.e., the upper end) protrudes from the base (22) to a set height and is erected. The pipe support (60) can lift the pipe (40) from the base (22) to a set height and support it horizontally. The other end (i.e., the upper end) of the pipe support (60) may further be equipped with a U-shaped fixing member capable of wrapping and fixing a circular pipe (40).

As one embodiment of the present invention, the pipe (40) may be any of various types of pipes that can be installed along the pipe installation conduit (30) in a pit (20) formed under the ground where the fuel pump (10) is installed. For example, the pipe (40) may include all hazardous material pipes of a gas station (e.g., fuel pipe, underfloor heating pipe, vent pipe, vapor recovery pipe, etc.), and such pipes (40) are installed in the pit (20) so that workers can easily check the condition of the pipes from above the ground.

Referring to Fig. 5, it can be seen that a pit (20) is formed on the ground where the fuel pump (10) is installed, that is, the lower portion of the fuel pump installation surface (11), and a cover (50) is installed on the open upper portion of the pit (20). The pipe (40) is supported horizontally at a certain height from the floor so as not to touch the floor by a pipe support (60) and can be connected to an underground tank (3).

[sleeve]

In a gas station pipe installation structure (1) according to one embodiment of the present invention, a cover (50) refers to a cover member that is openably and closably connected to an open upper portion (21) of a pit (20).

As one embodiment of the present invention, the cover (50) is connected to cover the open upper part (21) of the pit (20), thereby protecting the pipe (40) installed in the pipe installation conduit (30) from the outside.

In addition, the cover (50) has a number of holes (52), thereby allowing the status of the pipe (40) installed in the pipe installation conduit (30) to be easily inspected and confirmed with the naked eye from the ground (11).

In addition, the cover (50) is configured as a detachable structure that can be covered and combined with the open upper part (21) of the pit (20) or lifted and separated, so that damaged and aged pipes (40) can be easily replaced.

Specifically, as one embodiment of the present invention, the cover (50) includes a cover body (51) and a hole (52) (see FIG. 2).

The cover body (51) refers to a cover having a size corresponding to the open upper portion (21) of the pit (20). And, a hole (52) is formed in the cover body (51).

Here, the hole (52) can be formed by penetrating the cover body (51) in the thickness direction.

The hole (52) allows the condition of the pipe (40) installed in the pipe installation conduit (30) to be checked visually at any time without separating the cover body (51) while the cover body (51) is connected to the upper portion (21) of the pit (20).

For example, the cover (50) can utilize a grating member.

In other words, the cover (50) has a size corresponding to the open upper portion (21) of the pit (20), and may use a grating member in which a plurality of holes (52) are formed in a slit or lattice structure. The grating member is a type of cover in which holes (52) in a slit or lattice structure are formed penetrating in the thickness direction. The grating member has a structure in which the open upper portion of the pit (20) is physically blocked to protect the pipe (40) from the outside, while allowing the pipe (40) installed in the pit (20) to be visually checked through the holes (52). Accordingly, the pipe (40) installed in the pit (20) is protected with sufficient rigidity, while allowing the worker to check the condition of the pipe (40) at any time.

[Gathering device]

In a gas station pipe installation structure (1) according to one embodiment of the present invention, the fuel collecting device (70) refers to a device that collects fuel leaked from a pipe (40). The fuel collecting device (70) is configured to collect fuel leaked from a pipe (40) installed in a pipe installation conduit (30) in a pit (20) in order to prevent soil contamination, etc., caused by fuel leaking therefrom.

As one embodiment of the present invention, the oil collection device (70) includes a water collection unit (71), a water transfer line (72), and a water separation unit (73) (see FIGS. 4 and 6).

The water collection unit (71) can collect and store water that has been drained through the cover (50) and collected inside the pit (20) or oil that has leaked out from the pipe (40) inside the pit (20). The water transfer line (72) refers to a line that transfers the water collected in the water collection unit (71). In addition, the water separation unit (73) refers to an oil separation tank that receives the water using the water transfer line (72) and separates the water.

Preferably, as one embodiment of the present invention, the water collection unit (71) can be connected to at least one end of the pit (20) so as to be connected to the pipe installation conduit (30) (see FIG. 6).

In addition, the water collection unit (71) is provided with a water collection space having a predetermined size to collect the water or oil, and the water collection space can be formed at a lower position than the base unit (22).

Specifically, as one embodiment of the present invention, the upper height of the water collection unit (71) may be formed to be equal to or lower than the height of the base unit (22). Accordingly, the water collected inside the pit (20) may flow along the base unit (22) to the water collection unit (71) and be collected.

Meanwhile, as an embodiment of the present invention, the collecting device (70) may include a pump (711), a controller (712), and a sensor (713).

The pump (711) is connected to the water transfer line (72) and causes the water collected in the water collection unit (71) to flow through the water transfer line (72) to the water separation unit (73). The controller (712) controls the operation of the pump (711). In addition, a sensor (713) can be installed in the water collection unit (71) and can detect the water level of the water collected in the water collection unit (71).

The controller (712) can control the operation of the pump (711) based on the water level information detected by the sensor (713).

Preferably, as an embodiment of the present invention, a plurality of sensors (713) may be provided. The plurality of sensors (713) may be positioned at different heights within the water collection unit (71). Accordingly, each of the plurality of sensors (713) may individually detect the water level of the water at different heights, transmit a detection signal to the controller (712), and actively and precisely control the operation of the pump (711).

Meanwhile, a gas station pipe installation structure (1) according to one embodiment of the present invention further includes a vapor detection sensor (25) (see FIG. 4).

The vapor detection sensor (25) can be installed in the pit (20). The vapor detection sensor (25) is installed at a location adjacent to the pipe (40) and can detect vapor leaked from the pipe (40). In other words, the vapor detection sensor (25) detects vapor components that have spread around the pipe (40) and enables real-time detection of whether or not there is an oil leak.

As described above, according to the configuration and operation of the present invention, the pipes can be centrally arranged so that they are exposed to the ground by using a pit, which is a box-shaped concrete structure formed under the installation surface of the fuel pump where the fuel pump is installed and has an open upper portion. Through this, unlike the existing method of burying the pipes underground and constructing them, the pipes constructed in the pit are exposed through the ground, so that visual inspection of the pipes can be performed at all times after the pipes are constructed. As a result, the pipes can be inspected easily, and the pipes can be replaced without missing the pipe replacement period.

In addition, according to the configuration and operation of the present invention, the pipes of a gas station can be centrally arranged so that they are exposed on the ground using a pit-shaped cold-formed pipe installation conduit, so that the construction work of the pipes is convenient, and the convenience of inspection and replacement of the pipes after construction can be improved.

In addition, according to the configuration and operation of the present invention, even if an oil leak occurs from a pipe, it can be quickly monitored by the user through an oil vapor detection sensor, and the leaked oil can be collected into an oil-water separation unit using a separate oil collection device, thereby preventing soil contamination due to the oil leak in advance.

Although the present invention has been described with reference to the drawings as examples, it is obvious that the present invention is not limited to the embodiments and drawings disclosed in this specification, and that various modifications can be made by those skilled in the art within the scope of the technical idea of the present invention. In addition, even if the effects according to the configuration of the present invention were not explicitly described while describing the embodiments of the present invention, it is natural that the effects that can be predicted by the corresponding configuration should also be recognized.
