Description

Reinforcement block for retaining wall and installation method {The installation method for reinforcing block of retaining wall type}

The present invention is to install the retaining wall reinforcement block in the low fill part or soft ground such as slopes such as rivers, roads, retaining wall, embankment, and install the retaining wall to endure the earth pressure with only the concrete weight of the retaining wall reinforcement block. It relates to a method for installing the reinforcement soil block for the retaining wall that can be single-sided.

In general, the retaining wall reinforcement block for the retaining wall is to prevent deformation and collapse due to the loss of the soil in the fill land or incision, and such a retaining wall reinforcement retaining wall for the masonry retaining wall is the construction of apartment complex, construction of road cut soil, slope stability It is widely used for construction for securing, bridge wing wing construction, and other waterways and embankments.

Therefore, the retaining wall is mainly composed of concrete, stone, brick, wood, etc., and the retaining wall block is made of various forms such as stone and concrete furnace. Reinforcement blocks for retaining walls are constructed horizontally and superimposed on one another to form walls. Retaining walls generally have a structure of protrusions and grooves that allow the rows of adjacent blocks to join together to form an upright wall, and have inner holes open up and down to induce drainage by laying gravel.

In addition, the construction method of constructing the reinforced earth retaining wall structure in a prefabricated manner may form the retaining wall by placing concrete in the site before.

Therefore, in order to solve the problems of various closures generated in the conventional retaining wall construction method, that is, prolonged construction period, impossibility of winter construction, limitation of construction height, excessive cost and enormous manpower input, Currently, most constructions are prefabricated panels or reinforced earth blocks.

However, it is expensive to construct retaining walls with prefabricated panels, and it takes a lot of time and labor to construct them. However, retaining walls stacked using reinforcement soil blocks can be applied to various terrains because the reinforcement blocks are not connected to each other. Although there is an advantage in saving time and labor, there is a certain limit to endure the soil pressure from the ground behind the retaining wall in the case of simply stacking blocks.

 Therefore, in recent years, efforts have been made to overcome this by providing a connection groove in the reinforcement earth block, but it is difficult to obtain a desired result in the technical field of the present invention, and there is a problem in that the structure or installation method is complicated and economic efficiency is low.

In order to solve the above problems, the present invention uses a plurality of retaining wall blocks for retaining wall having a predetermined shape to be fixed up and down when connecting up and down, and the front and rear of the reinforcing soil block is inserted into the connecting ring to fix the ground behind the retaining wall. The main purpose of the present invention is to provide a retaining wall reinforcement block and a method for installing the retaining wall to prevent the retaining wall from being driven by pressure.

As described above, the present invention is a gravity retaining wall using concrete self-weight of reinforcement soil block, and is generally easy to install in low fill part or soft ground, and it can endure earth pressure only by concrete self-weight, minimizing construction cost, and shortening air by fast construction property. It can work.

 Therefore, the present invention reinforcement earth block can be built stably and firmly, by inserting the reinforcing block into the connecting ring to prevent the settlement of the back ground of the retaining wall and to increase the binding force with the reinforcement earth block.

In addition, the present invention can prevent the filling phenomenon of the reinforcement soil block by strengthening the lateral coupling force, it is possible to improve the efficiency of the earth wall compaction work behind the reinforcement soil block to obtain the compaction effect of the soil wall.

Hereinafter, described in detail the present invention by the accompanying drawings as follows.

The present invention can be divided into first and second reinforcement soil block (1, 2) to build the retaining wall (9) by masonry reinforcing soil block, the first reinforcement soil block (1) is a rib pattern on the front to produce a beautiful (8) is formed, the connecting pin (5) is formed so that the connecting pin (5) is inserted into the upper surface and the lower surface to insert the connecting pin (5) in the same position, the upper surface is located in the rear The connecting ring insertion groove 4 is formed to be connected to the second reinforcement block 2 and has a shape in which one side of the connecting ring 7 is vertically bent at both ends.

In addition, the second reinforcement earth block (2) forms a space portion 6 to fill the rubble through the center, and the connecting ring insertion grooves (4) are formed at the front and rear of the upper surface so that both ends are vertically bent. One side of the link ring 7 is formed to be fitted.

Therefore, the first reinforcement soil block 1 is positioned at the lower end, and a plurality of second reinforcement soil blocks 2 are connected to the rear surface of the first reinforcement soil block 1 in a line, and the upper surface of the first reinforcement soil block 1 is present. Insert the connecting pin (5) into the connecting pin insertion groove (3) formed in the insertion ring (4) in the connecting ring insertion groove (4) of the first and second reinforcement earth block (1, 2).

Then, the first and second reinforcement earth blocks 1 and 2 positioned in a line may be firmly fastened in a line.

In addition, the upper end of the first reinforcement soil block (1) located in the lower end by inserting the connecting pin (5) into the connecting pin insertion groove (3) formed on the lower surface of the other first reinforcement soil block (1), and the lower end and Similarly, a plurality of first reinforcement soil blocks 1 are connected in a row, and in this case, the number of second reinforcement soil blocks 2 is preferably reduced by one space and stacked in a stepwise manner.

Figure 3a, b, c is an exemplary view showing the construction state of the reinforcement soil block of the present invention, Figure 3a is a retaining wall is built in a vertical line, Figure 3b is the inclination angle as the upper up when the first reinforcement soil is laid It can be constructed to have.

The first reinforcement soil block 1 can be assembled to have an inclination angle when the first reinforcement soil block 1 is stacked one by one because the connection pin insertion groove 3 formed on the lower surface is larger than the connection pin 5. Positioned so as to pull rearward little by little each time is positioned to have an inclination angle, it can be fixed with the second reinforcement soil block (2) by inserting the connecting ring (7) in the connecting ring insertion groove (4) located in the rear.

3C and 4 alternately stagger the first and second reinforcement soil blocks 1 and 2 in a zigzag shape to firmly assemble the retaining wall 9.

Therefore, in the embodiment of the present invention, the rear end of the first reinforcement soil block 1 and the front surface of the second reinforcement soil block 2 are in close contact with each other, and the connecting ring 7 is inserted into the connection rings of the first and second reinforcement soil blocks 1 and 2. Insert the connecting ring (7) into the groove (4) to be fixed, and a plurality of second reinforcing soil block (2) in the rear of the second reinforcement soil block (2) in a row by any number in the connection ring (7) Insert into the connecting ring insertion groove (4) and fix it.

In addition, when the connecting pin 5 is inserted into the connection pin insertion groove 4 formed on the lower surface of the first reinforcement soil block 1 on the lower first reinforcement soil block 1 located at the lower end, the shear force is excellent.

Accordingly, while the first and second reinforcement soil blocks 1 and 2 are assembled by the same method as described above, the installation lengths of the blocks 1 and 2 positioned at the lower end thereof are installed by about 0.7 H of the height of the retaining wall 9.
