Description

The present invention relates to a drainage basin provided in piping such as a sewer, and an inner sub-pipe disposed in the drainage basin, and belongs to a sewage piping laying technique.

  Drainage pipes such as sewers for detached houses are widely used for checking the pipes and for joining the drainage branch pipe to the drainage main pipe. In order to control the flow path of the drainage flowing from the drainage branch pipe, a pipe body called an inner / sub pipe is usually provided inside or outside the drainage.

  In other words, when the drainage basin is installed, it is extremely rare that the level of burying of the drainage main pipe and the drainage branch pipe is the same, and in many cases, the drainage branch pipe is higher than the drainage main pipe. For this reason, there is a drop in the junction between the drainage branch pipe and the drainage main pipe. If this drop is large, the drainage flowing from the drainage branch pipe will scatter, and the inner wall of the drainage will be eroded and worn out. An inner sub-pipe is provided to prevent splashing and wear of the drain.

  For example, in Japanese Patent Application Laid-Open No. 8-109647 (patent document), a small manhole having a connecting frame body in which a rising pipe formed at the upper part of an invert portion is divided and a branch connection port is provided in the middle. It is disclosed that an inner sub-pipe for connecting a lower end opening portion to an invert portion and connecting an upper end portion to the outlet of the branch connection port is provided inside or outside the manhole.

In JP 2004-278095 A (patent document), in a drainage drain comprising an inspection cylinder and an invert, an inlet is provided in the upper part of the drainage basin, and the inlet and the invert outlet are connected to a U There is disclosed a drainage drain installed in a house that incorporates a guide member that makes a turn-like flow. This guide member is the inner sub-pipe itself.

  The drainage basin according to the present invention has a drainage inflow portion that opens upward in a funnel shape and a drainage outflow portion that is connected to the lower portion of the drainage inflow portion and opens in the flow direction of the drainage flowing through the invert portion. Since the pipe is adopted, it is not necessary to consider the position of the drainage branch pipe, and hence the branch pipe attachment part of the drainage drain, when installing the inner sub-pipe, and the drainage outflow part in the direction of the drainage flowing through the invert part The drainage from the drainage branch pipe can be easily joined to the drainage main pipe simply by matching the openings.

  Further, the drainage inner sub-pipe of the present invention includes a drainage inflow portion that opens upward in a funnel shape, and a drainage outflow portion that is connected to the lower portion of the drainage inflow portion and opens in the flow direction of the drainage flowing through the invert portion. Because it can be attached to the drainage without being restricted by the installation position of the drainage branch pipe and branch pipe attachment part, there is no need to arrange a wide variety of inner and secondary pipes as in the past, Management of product inventory and workability of drainage can be remarkably improved.

  Furthermore, if the drainage outflow part at the lower part is formed of a material that can be deformed according to the flow force and / or flow rate of the drainage that flows through its own weight or the invert part, the drainage does not flow through the inner and secondary pipes. The drainage outflow part is reduced in size and does not obstruct the flow of drainage flowing through the invert part. When the drainage flows through the inner sub-pipe, the drainage outflow part expands according to the flow force and / or flow rate. In addition, there is an excellent effect that the waste water flowing out from the drainage outflow portion can be matched with the flow direction of the wastewater flowing through the invert portion of the drainage.

  Furthermore, the drainage outflow part of the inner sub-pipe is a soft resin or cloth cylindrical body, and one end of the lower end part of the drainage outlet is provided by a stopper provided at the upper part of the drainage outlet of the invert part. By engaging with the upper part, the drainage outflow part of the inner sub-pipe can be directed very easily in the flow direction of the drainage flowing through the invert part of the drainage. In addition, by combining with the drainage inflow part, the inner sub-pipe can be attached regardless of the attachment position of the drainage branch pipe, and the effect of eliminating one of the restrictions in the installation of the drainage can be achieved.

  Further, in the drainage basin of the present invention, a screwing means is also used in assembling the inspection cylinder composed of an invert portion, a riser pipe or an adjuster which has been joined by fitting and, if necessary, using an adhesive. In particular, by using a ring body, the assembly workability can be remarkably improved. The center of the drain pipe connecting part of the invert part and the drain pipe connected thereto and the surface of the lid part on the ground surface (GL) Surface alignment, in particular, alignment between the connecting portion provided on the adjuster and the drainage branch pipe can be performed very easily. Therefore, the adjustment work of the burial position of the drainage can be made extremely easy without requiring skill.

Further, in the present invention, if the inner and auxiliary pipes can be detachably attached to the drainage basin, the drainage basin can be easily inspected and cleaned, and can be easily assembled. .

  Hereinafter, the drainage basin and drainage basin subpipe of the present invention will be described in detail with reference to the drawings.

  A drainage trough 1 shown in FIG. 1 is connected to an invert portion 3 in which drain mains 2 and 2 are respectively connected to opposing wall surfaces, and a short portion 4 that is integrally formed on the upper portion of the invert portion 3. It is composed of a cylindrical riser 6, an adjuster 7 connected to the riser 6, and a lid 9 attached to the upper part of the adjuster 7. A tube 13 is detachably attached. The lid portion 9 includes a lid receiving frame portion 10 attached to the upper end portion of the adjuster 7 and a lid 11 provided on the lid receiving frame portion 10 so as to be freely opened and closed.

  In this embodiment, the rising pipe 6 and the adjuster 7 connected to the riser pipe 6 constitute an inspection cylinder 5. A drainage branch pipe 12 is connected to a required portion of the adjuster 7. A connecting portion 8 is integrally formed. In addition, as long as this inspection cylinder 5 has the connection part 8 of the drainage branch pipe 12, it is natural that you may comprise one cylindrical body of required length. In addition, since the said connection part 8 becomes a drainage inflow port from the drainage branch pipe 12 substantially, in this specification, it may be called a "branch pipe inlet" as needed.

  The inner sub-pipe 13 is composed of a drainage inflow portion 14 that opens upward in a funnel shape, and a drainage outflow portion 16 having an opening 17 connected to the lower portion of the drainage inflow portion 14. It is made of a relatively hard synthetic resin such as a vinyl chloride resin. The drainage inflow portion 14 has an inspection cylinder 5 at its upper end opening, and in this embodiment, has an overhang edge 15 having an outer diameter substantially equal to the inner diameter of the adjuster 7, and this overhang edge 15 is formed at the lower end opening of the adjuster 7. It is configured to be held in the inspection cylinder 5 by contacting the ring-shaped locking edge 18 formed in the section from above.

  As shown in FIG. 1, the inner sub-pipe 13 can be drained by a very simple means of placing the protruding edge 15 of the drainage inflow portion 14 on a locking edge 18 provided in the lower end opening of the adjuster 7. Can be installed in one more. Further, by attaching a gripping part 19 integrally to the upper part of the drainage inflow part 14 and using the gripping part 19, the inner sub-pipe 13 can be easily attached to and detached from the drainage basin 1.

  The inner sub-pipe 13 in FIG. 1 is fixed using the overhanging edge 15 provided on the upper portion, but the fixing method is not limited to this, and although not shown, It can also be fixed by a projection provided on the outer wall of the tube 13 and a groove-like projection or a flat projection provided on the inner wall of the adjuster 7 for receiving the projection.

  As shown in FIG. 1, the drainage inflow portion 14 of the inner sub-pipe 13 of the present invention has a circular funnel shape with no upper direction, so that the opening 17 of the lower drainage outlet 16 is connected to the adjuster. Since the direction of the drainage flowing through the drainage pipe 7 only needs to be matched with the direction of the drainage main pipe 2, conventionally, the inside of the drainage branch pipe is adjusted to the position of the connecting portion 8 for connecting the drainage branch pipe 12. The trouble of having to prepare a secondary pipe can be completely eliminated. Moreover, conventionally, when the connecting portion 8 cannot cope with the diversity of piping, a universal joint or a curved pipe has been used. However, the inner auxiliary pipe of the present invention requires such an auxiliary material. But it's not.

  Furthermore, since the inner subpipe 13 of the present invention does not correspond to the drainage branch pipes 12 unlike the conventional one, even if there are a plurality of drainage branch pipes 12 connected to the drainage drain 1, there is no problem. In addition, since it can be handled by a single inner sub-pipe 13 without being affected by the number thereof, the handling thereof is greatly simplified as compared with the conventional structure.

  When connecting a plurality of drainage branch pipes 12 to the drainage basin 1, as shown in FIG. 2, if the plurality of drainage branch pipes 12 are installed in a cyclone type, Since the flow in the secondary pipe 13 becomes smooth, this is a preferable method as a connection method.

  1 has a form in which the rising pipe 6 is fitted into the rising part 4 of the invert part 3, and a screw is formed on the outer surface of the lower end of the rising pipe 6, and screwed into this screw. Since the screw to be rotated is provided on the inner surface of the rising portion 4 of the invert portion 3, when the rising tube 6 is rotated while meshing the screws, the rising tube 6 moves up and down, and the rising tube 6 and the invert portion 3 Increase / decrease of the fitting portion at the rising portion 4, that is, the position (height) of the adjuster 7 can be arbitrarily determined, and can be aligned with the ground surface (GL), and further aligned with the drainage branch pipe 12. Adjustment of the burying position can be easily performed without complicated work, and fine adjustment can be easily performed.

  Further, the adjustment of the buried position, which is conventionally performed, that is, the rough adjustment is performed by cutting the riser pipe 6, the adjuster 7, and further the lid receiving frame portion 10 and the like. The number of types can be reduced, and more efficient work can be performed.

  In addition, about the screw provided in the rising pipe 6 or the rising part 4 of the invert part 3, there is no restriction | limiting in particular in a magnitude | size and a shape, Screws, such as a multi-thread screw and a square screw, are also used. Moreover, although the riser pipe 6 is fitted into the riser 4 of the invert part 3 and the screw is provided, it is also possible to reverse the fitting state and provide the screw.

  Furthermore, the same measures can be taken for the lower end of the lid receiving frame 10 and the upper end of the adjuster 7, and the lower end of the adjuster 7 and the fitting surface of the riser pipe 6, and the lid 11 and the ground surface (GL) Surface matching can be performed easily.

  There are no particular restrictions on the size and shape of the screws provided in each member, and a screw such as a multi-thread screw or a square screw is also used. In addition, when each member is fitted with a screw, an adhesive, which is also used in the conventional fitting, can be used together to make liquid tightness more complete.

  3 and 4 has basically the same configuration as the drainage trough 1 shown in FIG. 1 above, so the same parts are indicated by the same reference numerals, but are installed in the drainage trough 20. The configuration of the inner sub-pipe 21 is different.

  That is, the inner sub-tube 21 mounted in the drainage basin 20 is a drainage outflow having a funnel-like resin-made drainage inflow portion 22 opened upward and an opening 25 connected to the lower portion of the drainage inflow portion 22. The drainage inflow portion 22 has a projecting edge 23 having an outer diameter substantially equal to the inner diameter of the adjuster 7 constituting the inspection cylinder 5. Is held in the inspection cylinder 5 by abutting from above the ring-shaped locking edge 29 formed in the lower end opening of the adjuster 7.

  At that time, instead of the resin material such as vinyl chloride in the embodiment, the drainage outflow portion 24 is changed to the flow force and / or flow rate of the drainage flowing through the drainage main pipe 2, and further to the own weight of the drainage outflow portion 24 itself. It is formed of a cylindrical body made of soft resin or cloth that can be deformed accordingly.

  The drainage outflow portion 24 formed of a material that can be deformed in accordance with the flow force and / or flow rate of the drainage flowing through the drainage main pipe 2 and further its own weight, First, it is locked to a stopper 26 provided at the upper part of the drainage outlet X in 20.

  When the drainage from the drainage branch pipe 12 flows in through the drainage inflow portion 22 that opens upward in the funnel shape, the inner auxiliary pipe 21 having the above configuration expands and passes the drainage as shown in FIG. Since one end of the lower opening 25 is locked to the upper part of the drainage outlet X, the direction of drainage is made to coincide with the direction of drainage flowing through the drainage main pipe 2, and they are merged. is there.

  When the inflow of the drainage from the drainage branch pipe 12 to the inner auxiliary pipe 21 is stopped, the inner auxiliary pipe 21 is deformed and reduced by its own weight as shown in FIG. Even if the reduced lower part of the inner sub-pipe 21, that is, the drainage outflow part 24 remains in the invert part 3, it does not oppose the drainage flowing through the invert part 3 in terms of material and does not hinder the flow of drainage.

  In addition, since the inner sub-pipe 21 can be freely removed, when inspecting and cleaning the drain 20, the inner sub-pipe 21 is removed from the inspection cylinder 5 by using the grip portion 27. Internal inspection can be performed easily and cleaning can be easily performed.

  Also in the drain 20, the rising pipe 6 has a form fitted into the rising part 4 of the invert part 3, and a screw is provided on the outer surface of the lower end part of the rising pipe 6, and is screwed into the screw. A ring body 28 is provided on the outer periphery of the riser 6. Therefore, when the ring body 28 is rotated while the screws are engaged with each other, the ring body 28 moves up and down to increase or decrease the fitting portion between the rising pipe 6 and the rising portion 4 of the invert portion 3, that is, the position of the adjuster 7 ( (Height) can be arbitrarily determined, and adjustment of the buried position such as alignment with the ground surface (GL) and alignment with the drainage branch pipe can be easily performed without complicated operations. And fine adjustment can be easily performed.

  Further, the adjustment of the burying position which has been conventionally performed, that is, the rough adjustment is performed by cutting the riser pipe 6, the adjuster 7, and the lid receiving frame portion 10 and the like. The number of types can be reduced, and more efficient work can be performed.

  The screws provided in the riser 6 and the ring body 28 are not particularly limited in size and shape, and screws such as a multi-thread screw and a square screw are also used. In FIG. 3, the riser 6 is fitted into the riser 4 of the invert part 3 and a screw is provided on the outer surface of the lower end of the riser 6. A screw may be provided on the outer surface of the upper end portion of the rising portion 4 provided in the portion 3, and a ring body 28 to be screwed thereto may be provided.

  Further, the same measures can be taken on the fitting surfaces of the lower end portion of the lid receiving frame portion 10 and the upper end portion of the adjuster 7, and the lower end portion of the adjuster 7 and the upper end portion of the rising pipe 6, and the lid 11 and the ground surface (GL ) Can be easily performed.

  Furthermore, there are no particular restrictions on the size and shape of the screws provided in each member, and a screw such as a multi-thread screw or a square screw is also used. Moreover, when each member is fitted with a screw, it is the same as the above that the liquid-tightness can be made more complete by using an adhesive, which is also used in the conventional fitting.

  Note that when the above members are fitted using screws, it is desirable to use the seal ring material 30 in order to provide the fitting surface with a sealing property. Is maintained and drainage leakage is prevented. Furthermore, even when these members are fitted with screws, an adhesive, which is also used in the conventional fitting, can be used together to make liquid tightness more complete.

  As described above, the inner sub-pipe 13 or 21 in the drainage basin of the present invention includes a drainage inflow portion that opens upward in a funnel shape, and a drainage outflow portion having an opening that is connected to the lower portion of the drainage inflow portion. Furthermore, the lower drainage outflow part forming the inner sub-pipe is formed according to the flow force and / or flow rate of the drainage flowing through its own weight or invert part such as a soft resin or cloth cylindrical body. By forming it with a deformable material, it is possible to attach the inner sub-pipe regardless of the attachment position of the drainage branch pipe.

  In particular, by fixing one end of the lower end portion of the drainage outflow portion made of a soft resin or cloth cylindrical body to the stopper 26 provided at the upper portion of the drainage outlet X of the invert portion 3, Regardless of the position of the branch pipe 12, the flow of waste water flowing from the drain inflow part (connection part 8) connected to the drain branch pipe 12 can be matched with the flow direction of the waste water flowing through the invert part 3. Therefore, it is not necessary to prepare various types of inner and secondary pipes according to the position of the drainage branch pipe 12, and the present invention is widely applicable without being limited by the position and number of drainage branch pipes.

Further, if the drainage / outflow portion 24 at the lower portion of the inner sub-pipe 21 according to the present invention is formed of a material such as a soft resin or cloth cylindrical body, the length can be easily adjusted by cutting or the like. be able to. Further, a hole for locking to the stopper 26 provided at the upper part of the drainage outlet X can be easily adjusted. In addition, it is possible to provide a plurality of holes suitable for locking in advance in the drainage outflow portion 24 that forms the lower end portion of the inner sub-pipe 21, and this is a preferable method because the hole portion can be reinforced.

The drainage basin and drainage basin pipe according to the present invention achieves the original purpose of preventing the sewage from splashing and drainage drainage. It can be installed regardless of the location of the drainage branch pipe, eliminates one of the limitations of drainage drainage installation, does not impede the flow of drainage flowing through the invert section, and Is the centering of the drain pipe connection part of the invert part of the drainage and the drain pipe connected to it, the surface of the lid part to the ground surface (GL), especially the branch pipe connection part provided on the adjuster And the drainage branch can be aligned very easily. Further, since the adjustment work of the drainage burial position at the sewer laying site can be made extremely easy without requiring skill, it can be widely used in the civil engineering and construction related industries.
