Description

Retaining Wall Blocks {Block for retaining wall}

The present invention relates to a retaining wall block, and more particularly, to an eco-friendly ecological retaining wall block that is constructed on slopes such as rivers, reservoirs, and road cutouts.

A method of protecting slopes such as rivers, reservoirs, and road cuts is to install retaining wall blocks and to provide vegetation spaces for plants to grow on the blocks. Such retaining wall blocks can restore natural ecosystems, control the flow rate of water and prevent ground subsidence by plants growing in the vegetation space, and have functions as habitats and spawning places for aquatic insects, fish, and birds.

In general, various types of retaining wall blocks, canine blocks, precipitation, concrete retaining walls, etc. are installed in river banks to prevent erosion and settlement of the ground and to prevent loss of waterways. Most conventional retaining wall blocks are not compatible with the river's surroundings but also cause disruption of the river ecosystem. Therefore, in recent years, environmentally friendly retaining wall blocks in harmony with the conservation of ecosystems and the surrounding environment of rivers have been preferred.

However, the conventional retaining wall blocks have trapezoidal fitting protrusions protrudingly formed on both left and right sides of the rectangular body, and fitting portions of the adjacent blocks are formed by fitting portions into which the third fitting protrusions are fitted on both front and rear sides of the body. Most of the construction is fitted to each other.

The conventional retaining wall blocks have a vegetation space for forming green space, but in the construction of the block, the coupling protrusion is inserted into the coupling groove, so that no separate coupling means is provided, and the gap between the blocks is relatively large. As construction increases, there is a high possibility of loss of binding force between blocks due to heavy rainfall, and when one block is lost, the mutual coupling force between blocks decreases significantly. There was a problem that caused a great damage to be lost.

In addition, the conventional retaining wall has a problem that the vegetation space is narrow and the side of the retaining wall is thick, it is difficult for the plants growing in front of the block to fully adhere to the soil of the back of the retaining wall.

It is conceived to solve the above problems of the present invention, simplifying the structure of the conventional retaining wall block and instead install additional reinforcing members in the horizontal direction to install on the retaining wall or to install the steel bar or tension bar in the vertical direction It is an object of the present invention to provide a retaining wall block with a maximum coupling force to prevent chain separation of the retaining wall block.

Another object of the present invention is to provide a retaining wall block that can improve the vegetation conditions by providing a planting port in the backfill rubble and installing a connecting pipe between the planting port and the body in order to provide better conditions for the vegetation growing in front of the body. To provide.

In addition, the connection pipe 84 may be installed to penetrate the planting and drain hole 18 formed in the main body 10.

Construction of the retaining wall block according to the present invention can be arranged as follows.

First, in order for the plant to be planted in the planting space in front of the retaining wall block, the connecting pipe 84 is constructed so as to penetrate the block body 10 and the retaining wall 20, respectively, and planting at the other end of the connecting pipe 84 The port 82 is constructed.

Referring to the construction method of the retaining wall block according to a preferred embodiment of the present invention based on the configuration and arrangement as described above are as follows.

(1) When each end is connected by a tension bar

First, 'digging' is required for slopes such as rivers, rivers, and road cuts. Subsequently, as shown in FIGS. 2 and 5, the foundation concrete 50 is poured into a predetermined form. In this process, the base 42 of the coupling member 40, such as the tensile muscle, is embedded in the foundation concrete 50 and fixed. Next, the lowest stage (one stage) of the block is provided. In this process, each tension muscle must be inserted into the corresponding through hole 15.

2 and 3, one end of the reinforcing member 30 is fixed to the fixing groove 16 around the engaging protrusion 12 at the upper end of the main body 10 of the first stage block, and the other end thereof is retained wall. Position (20) where the construction will be. Then, after arranging the connection pipe 84 to a predetermined length, the planting port 82 is connected to the other end of the connection pipe 84. Next, rubble and soil are filled and compacted by a predetermined length to construct the retaining wall corresponding to the first-stage block. Here, the planting port 82 is preferably to be located in the rear of rubble and soil.

Next, two stages of a block main body are provided. In this process, the two-stage main body 10 is installed in a zigzag in the vertical direction so that the first-stage main body 10 and 1/2 overlap, and the coupling groove 14 at the lower end of the two-stage main body 10 is the first-stage main body. It is inserted into the engaging projection 12 of (10). Insertion of the coupling member into the through-hole in the installation of the two-stage block, installation of the reinforcing member 30 and the planting port 82, filling and compacting process of rubble and soil is the same as the one-stage construction described above.

Next, the steps of the block having the required height are continuously constructed in the above-described process. After constructing the block stage repeatedly to the required height, cast the top concrete on the top block and finish it.

(2) When connecting multiple stages with steel bars

This construction method installs the first stage of the block directly without constructing the tensile muscles during the foundation laying work after the trenching work. Subsequently, after the reinforcing member, planting port is installed, the same process is sequentially performed as required height after the rubble and soil filling and compacting process is the same as the above-described construction method.

However, after constructing the retaining wall to the required repetition height, the steel rod is inserted from the upper surface of the uppermost block to the lowermost block into each through hole 15 formed as one hole in the adjacent stage before placing the upper concrete. Subsequently, the finishing work after pouring the top concrete is the same as the electric installation example. In this process, by inserting a hollow steel pipe into the through-hole 15 having a plurality of holes in the side, it is advantageous to fill the mortar when placing the upper concrete, and to further strengthen the bonding force between the blocks.

(3) In case of connecting blocks of adjacent stage with each steel bar

Unlike the second construction example, the construction method is constructed using the main bodies shown in FIG. 6. That is, a predetermined length is provided in the second through hole 17 provided at the upper end of the main body 10 of the block of the first stage after the process of installing the trench-foundation-reinforcement member, the planting port, rubble and soil filling and compaction process. Insert steel rods or steel pipes.

Subsequently, in the process of stacking the two-stage blocks, two-stage blocks are stacked while the third through holes 19 of the main bodies 10 are inserted into the pre-installed steel bars or the steel pipes 70. The remaining reinforcing members, planting pot installation and rubble and soil filling and chopping process are the same as the above-described construction example. This method has the advantage of reducing the cost of the steel bar while maintaining the same vertical coupling force as the second installation example.

The retaining wall block according to the present invention configured as described above has the following effects.

First, it is possible to prevent the loss of the retaining wall block by improving the bearing capacity of the retaining wall block through a reinforcing member connecting the rear of the retaining wall and the fixing groove provided between the constructed blocks.

Second, it is possible to finally prevent the loss of the retaining wall block by strengthening the vertical coupling force between the main body through the steel rod, steel pipe, tension bar, etc. penetrating the constructed blocks.

Third, planting ports can be installed on the rear surface of the retaining wall formed by rubble and earth and sand, and the planting efficiency can be increased through a connection pipe connecting the drainage hole of the block and the planting port.
