Description

Greening vegetation block for constructing retaining wall}

The present invention is to build a green retaining wall capable of incubating plants or small animals by stacking in a predetermined gradient so that the stuffed soil filled inside the concrete block is partially exposed to the front of the retaining wall while preventing the slope collapse of the cut soil. It relates to a plant retaining wall block to be used, in particular, by providing an adjustment means for changing the end position of the structural member installed on the top and bottom cross-section of the block in accordance with the gradient design conditions in front of the retaining wall in order to prevent the sliding of the blocks stacked up and down In addition, the present invention relates to a plant retaining wall block having a front gradient adjusting means capable of constructing a retaining wall structure having various grades using blocks manufactured in one type.

As is well known, retaining walls are civil structures that are constructed to stabilize slopes by supporting the soil on the back while reducing the amount of soil when the site is restricted in creating roads, railroads, complex factories, rivers, etc. in cut soil.

The retaining wall is constructed considering the topographical conditions and factors affecting the retaining wall after the construction of the retaining wall, and traditionally forms a form to cut the soil of the construction area or fill the valley part and the lower part of the mountain area, It was common to pour concrete and cure it, then build it by filling the soil and crushed stone on the back of the concrete structure.

However, such reinforced concrete retaining wall is not preferable in terms of cost and construction period because of the concrete to be molded in the field, and it is often difficult to secure mechanical allowable stress, and there is a problem that the appearance is not good.

In view of this, conventionally, a block retaining wall has been widely constructed in which a factory-made block is laminated in the field.

The block retaining wall is formed of a block of concrete or stone which forms the front wall of the retaining wall and prevents the soil from being pushed forward, the earth and sand filled in the rear of the block, and an appropriate anchor means. It is common to construct the back of the blocks stacked by stacking several layers with filling material such as crushed stone or earth and sand.

Thus, the retaining wall constructed by the blocks has a better aesthetics than the reinforced concrete retaining wall due to the site casting, but since the block is mainly formed of mortar or concrete, there is a limit in improving the aesthetics of the retaining wall because the intrinsic color of the mortar or concrete is expressed. .

Therefore, in order to improve the aesthetics of the retaining wall, the surface of the block may have a roughness, a pattern, or coloring at the time of manufacture.In this case, the manufacturing cost increases, and as the time passes after installation, the front of the retaining wall Because of this cloudiness, there is a temporary disadvantage that the aesthetic effect falls.

In addition, the existing block retaining wall blocks the space for vegetation to grow only in consideration of the stability of the slope, so that the heterogeneous landscape that does not fit with the surrounding environment cannot be avoided, and the habitat of microorganisms and small animals disappears and the natural ecosystem is destroyed. There is a problem.

As a result, the ecological environment of the retaining wall installed in the Saengseongbu area has been seriously recognized recently. As people's desire for environment-friendly urban landscape increases, attempts to regenerate and restore ecologically damaged environments are actively made. have.

As an example of such an attempt, concrete blocks are being introduced in various forms to enable the protection of slopes and to allow plants to grow to form environmentally friendly retaining wall structures.

Conventional environmentally friendly retaining wall is a type of concrete block that can be built, by laying a block in which the hollow part is formed by filling the soil in the hollow part by stacking a predetermined gradient, through the upper front of the block to the outside Box-type so-called plant retaining wall blocks that induce plant growth have been presented in various forms.

The present applicant has also developed a plant retaining wall block having the above concept and has been registered in Korea Utility Model Registration Nos. 20-0246799, 20-0247050, 20-0249172, and 20-0300440.

The planting retaining wall blocks according to the registration proposal form a hollow portion having the front and rear wall parts and the left and right wall parts integrally formed to open the upper and lower surfaces so as to fill the earth and sand, and stacked on the upper and lower ends of the left and right wall parts. Shear key portions interlocked with each other are formed to prevent sliding of the block.

Such planting retaining wall blocks are provided with a retaining wall structure in which vegetation is introduced through the earth and sand exposed by holes formed in the upper side or the front wall of the planting space part by constructing an inclined retaining wall having a predetermined law gradient while being stacked up and down. It is true that the shear key of the blocks is laminated while being engaged, so that a relatively stable structure can be constructed compared to other blocks.

However, the planting retaining wall blocks according to the registration proposal is one type because the shear key formed in the uneven shape on the upper and lower end surfaces of the block to prevent sliding of the blocks stacked up and down is formed into a standard product having a certain shape and position. There was a drawback that all of the retaining wall structures designed with various different gradients could not be dedicated to the blocks made by using them.

For example, a block 1 product standardized for use in constructing a retaining wall structure designed as a 1: 0.3 gradient as shown in FIG. 1A can be constructed as a retaining wall structure of a 1: 0.3 gradient, but is illustrated in FIG. As shown in the figure, such as 1: 0.4 or 1: 0.5, etc., it is not necessary to build retaining wall structures of other grades, so that the shear keys of upper and lower tier blocks (1) do not engage. There was an impossible disadvantage.

Accordingly, until now, the factory has manufactured and released blocks standardized in various models by changing the position of the shear key of the block in advance in consideration of the gradient design conditions of the retaining wall, which makes it difficult to supply the block quickly and thus prolong the construction period. In addition, the manufacturing cost of the block leads to an increase in the overall construction cost required to build the retaining wall, as a result directly or indirectly increases the cost.

In other words, in order to manufacture blocks standardized with various models in accordance with the design gradient of the retaining wall, molds required for forming the blocks also require various models. Generally, dozens of molds are required to produce only one model block. Considering the input situation, it is necessary to prepare hundreds of molds in order to manufacture three or more standardized large blocks, which not only requires excessive time and cost to manufacture the molds, but also causes storage problems of the large molds. There was a very uneconomical factor in productivity.

Therefore, it is determined that the above registration proposals should solve the above problems, and this is a matter that should be improved not only for the blocks according to the above registration proposals but also for other conventional plant retaining wall blocks in the form of a conventional box.

Therefore, the present invention has been made to solve the problems appearing in the vertically stacked structure of the box-shaped plant retaining wall blocks that enable the growth of plants while preventing the slope collapse of the cut soil, the object of the present invention is to be stacked up and down In order to prevent the sliding of the blocks, by adjusting the end position of the structural member installed on the top and bottom cross-section of the block according to the draft design conditions on the front of the retaining wall, the retaining wall structure of the various grades using the blocks made of one type It is to provide a plant retaining wall block is provided with a front gradient adjusting means that can be used universally in all the construction.
