Description

Reinforcement structure for retaining wall and installation method of retaining wall using same {Structure of reinforced for retaining wall and method for manufacturing of method install reinforced for retaining wall}

The present invention relates to a retaining wall reinforcement structure for preventing ground collapse inside the retaining wall and a method of installing the retaining wall using the same, and particularly, a recessed groove is formed in a block formed in the retaining wall and extends to the cut surface in the recessed groove. The extension reinforcement is integrated with the block by incorporating the suspension into the extension reinforcement and the joining reinforcement even if the earth pressure is generated by the filling material filled in the retaining wall by combining the coupling reinforcement covering both ends of the extension reinforcement introduced into the block with a combination. The present invention relates to a retaining wall reinforcement structure that can be supported horizontally and vertically so that the retaining wall can be firmly installed, and a method of installing the retaining wall using the same.

In general, the retaining wall is a wall that prevents soil from collapsing by resisting soil pressure, and is a structure for preventing ground collapse due to external force generated from the slope of the ground surface.

The retaining wall has a shape in which a plurality of blocks are stacked in stages therein, and one side of the reinforcement is seated on the block, and at the same time, the reinforcing material embedded in the retaining wall extends horizontally to the cut surface side and is embedded in the retaining wall. Since the position is fixed by the earth pressure of the filling material such as gravel and soil, the retaining wall constructed with blocks is tensioned to the cut surface side to prevent the fall of the retaining wall by lateral earth pressure.

However, these retaining walls are gradually settled as the compacted filler material is consolidated over time after being constructed. The reinforcement material is also removed from the block and cut surface along with the backing soil, and the block and cut surface are not supported. As a result, the blocks are oriented toward the cut surface side, so that the installation form of the blocks stacked in stages is deformed and locally collapsed, or excessive deformation is caused to cause the retaining wall to be filled, such as a retaining wall.

In order to compensate for this problem, one side of the reinforcement was fixed to the anchor bolt by inserting an anchor bolt in the block, but since the stress is concentrated at the fixing part between the anchor bolt and the reinforcement, the fixing part of the reinforcement is separated from the anchor bolt to completely solve the problem. It did not solve.

In addition, the reinforcing material has a certain strength and durability by weaving or arranging in a lattice form using polyester fibers, but the stability of the retaining wall has been deteriorated because it is somewhat insufficient to support the block and the cut surface only with these characteristics.

An object of the present invention devised to solve the above problems is to draw an engaging groove formed in the block formed in the retaining wall and to insert the interruption of the extension reinforcement extending to the cut surface to integrate the extension reinforcement with the block to bond strength By combining the coupling stiffeners covering both ends of the extension stiffener introduced into the block with a combination, the retaining wall can be supported horizontally and vertically due to the extension stiffener and the coupling stiffener even if earth pressure is generated due to the filling material filled in the retaining wall. It is to provide a retaining structure for the retaining wall that can be installed and a method of installing the retaining wall using the same.

The above object is achieved by the following configuration provided in the present invention.

Retaining wall reinforcement for the retaining wall according to the present invention and a method for installing the retaining wall using the same, in the retaining wall reinforcement structure for preventing the collapse of the retaining wall extending between a plurality of blocks and cut surfaces stacked step by step inside the retaining wall, is cut in the horizontal direction It is composed of a block in which an inlet groove is formed and a plurality of meshes are formed on the surface thereof and extend in the longitudinal direction. A plurality of extension reinforcement extending to the cut surface side, and a plurality of mesh is formed on the surface is coupled to the ends extending to the cut surface of the plurality of extension reinforcement is configured to accommodate the end of the extension reinforcement, formed on the surface Coupling stiffener which is configured so that the mesh is directed in the horizontal direction at the rear of the extension stiffener, and the end side of the extension stiffener Is inserted ridorok intersect each of the mesh reinforcing material coupled with the mesh characterized by comprising the bonded object promote bonding in a state for receiving the ends of the reinforcing material bonds the reinforcement extends.

In addition, the combination is characterized in that made of any one of a soft rubber, silicon and a metal plate.

In the retaining wall reinforcement according to the present invention and a method for installing the retaining wall using the same, an inlet groove is formed in a block constructed in the retaining wall, and both ends thereof are joined to the interruption of the extension reinforcement in the inlet groove, and both ends are joined by a reinforcing member. Since the mesh of the extension reinforcement is directed in the vertical direction and the mesh of the coupling reinforcement forms the retaining wall in the horizontal direction, the mesh is formed in the vertical direction of the extension reinforcement even if earth pressure is generated vertically or horizontally by the filler in the retaining wall. And by the mesh formed in the horizontal direction of the coupling reinforcing material to relax or support the earth pressure to significantly increase the stability of the retaining wall has the effect that can be installed to install a solid retaining wall.

In addition, the combination is composed of any one of a soft rubber, silicon and metal plate, and has a plastic deformation and restoring force to facilitate the insertion of the extension reinforcement and the combined reinforcement mesh, but the insertion position as long as the external force is not applied when the insertion is completed Departure can be prevented from, and also has the effect of increasing the bonding strength of the extension reinforcement and the bonding reinforcement by the strength of the metal plate.
