Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of reinforced soil, and in particular relates to a retaining wall with the reinforced soil anti-deformation function. Background Art
[0002] The reinforced earth retaining wall mainly includes a fill layer, a reinforcement layer in the fill, and a wall panel layer. It reduces the lateral pressure of the soil into the soil through the friction between the fill and the reinforcement to stabilize the soil. The reinforced earth retaining wall has good seismic resistance and is economical for slope reinforcement, so it is more and more widely used. However, traditional reinforced earth retaining walls have the problem of large deformation, so their application is limited in projects with relatively strict deformation requirements. The effect of the anti-deformation function is not ideal, which reduces the service life and function. When severe weather such as heavy rain occurs, it is easy to collapse and lose its protective function, which is easy to cause irreparable losses and is not convenient for anti-deformation use. Utility Model Content
[0003] The utility model aims to provide a retaining wall with a reinforced soil anti-deformation function to solve the problems raised in the above-mentioned background technology.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

The geogrid reinforcement frame is connected to the reinforced soil layer, the bottom end of the wall bottom layer is connected to the foundation column, and the upper end of the wall bottom layer is connected to the geogrid reinforcement frame through a connecting column, so that the geogrid reinforcement frame can be connected to the foundation column through the connecting column and the wall bottom layer, thereby enhancing the stability and improving the anti-deformation effect. The wall layer is composed of multiple groups of wall blocks spliced together to form a whole, which increases the overall stability of the wall layer. Multiple groups of reinforced soil layers are connected to the wall layer through connecting blocks, that is, the connecting blocks are connected to the corresponding wall blocks. When the reinforced soil layer at a certain position is severely deformed, the connecting blocks will be pushed by the reinforced soil layer and the corresponding wall blocks will be squeezed, so that the corresponding wall blocks move relative to other wall blocks, that is, protrude from the wall layer or are equivalent to the wall layer being recessed inward, so that it is easy for people to observe that the position has a more obvious deformation, which is beneficial to focus on the corresponding position and carry out prevention and control. A drainage group is arranged inside the fill layer, which can be beneficial to the discharge of accumulated water and prevent the accumulated water from eroding the inside of the earth wall.
[0007] Preferably, one side of the wall block is connected to a lateral limit block, and the other side of the wall block is provided with a lateral limit slot matching the lateral limit block, that is, the lateral limit block of one group of wall blocks can be installed inside the lateral limit slot of another group of wall blocks, so that the left and right groups of wall blocks can be combined and installed, the bottom end of the wall block is connected to a bottom side limit block, and the top of the wall block is provided with a bottom side limit slot matching the bottom side limit block. By setting the bottom side limit block of one group of wall blocks to be installed inside the bottom side limit slot of another group of wall blocks, the upper and lower groups of wall blocks can be combined and installed, which is conducive to combining multiple groups of wall blocks into a whole and improving overall stability.
[0008] Preferably, the lateral limit block is slidably connected to the lateral limit slot, the length of the lateral limit block is smaller than the lateral limit slot, the lateral limit block is located in the middle of the lateral limit slot, the bottom limit block is slidably connected to the bottom limit slot, the length of the bottom limit block is smaller than the bottom limit slot, and the bottom limit block is located in the middle of the bottom limit slot, that is, when the reinforced soil layer pushes the connecting block and squeezes the corresponding wall block, the corresponding wall block can move a certain distance relative to other wall blocks, so that it protrudes or recesses relative to other wall blocks, which is convenient for detecting that the corresponding position has a more serious deformation, which is conducive to timely prevention and control, but at the same time it will not separate from other wall blocks, and plays a limiting role.
[0009] Preferably, a concrete foundation layer is provided on one side of the bottom wall layer, a concrete capstone layer is provided on one side of the top wall layer, and an installation groove is formed between the concrete foundation layer and the concrete capstone layer, which is conducive to the installation of the wall block.
[0010] Preferably, the drainage group is arranged as a plurality of drainage channels, and the ends of the plurality of drainage channels close to the wall layer are lower than the ends away from the wall layer, that is, the drainage channels are arranged at an angle, which is conducive to the accumulated water flowing along the drainage channels toward the wall block, thereby facilitating the discharge of the accumulated water.
[0011] Preferably, a waterproof layer is provided inside the drainage channel to improve the drainage effect.
[0012] Compared with the prior art, the beneficial effects of the utility model are:

The movement of the wall blocks in a certain direction is also convenient for checking the occurrence of more serious deformation at the corresponding position, which is convenient for timely prevention and treatment, but at the same time it will not separate from other wall blocks and plays a limiting role.
