Abstract
Description
Technical Field
[0001] The present application relates to the technical field of retaining walls, and in particular to a retaining wall structure. Background Art
[0002] Retaining walls refer to structures that support roadbed fill or hillside soil and prevent fill or soil from deforming and becoming unstable. There are many types of retaining walls, including gravity retaining walls, anchored retaining walls, thin-walled retaining walls, reinforced soil retaining walls, etc. These retaining walls have their own characteristics. For example, gravity retaining walls balance the soil by their own gravity, anchored retaining walls are light retaining walls, thin-walled retaining walls are reinforced concrete structures, and reinforced soil retaining walls reduce the lateral pressure of the soil into the soil through the friction between the fill and the reinforcement to stabilize the soil.
[0003] Common retaining walls have a filter layer on one side of the retaining wall. The filter layer is mostly filtered by gravel, but some smaller impurities cannot be filtered and are easy to enter the pipe, causing pipe blockage. At the same time, some gravel is also easy to block the pipe mouth, causing blockage. When the accumulated water cannot be discharged, it is easy to increase the lateral pressure overturning moment of the retaining wall. Utility Model Content

[0013] Through the above solution, the strength of the wall can be further improved by setting vertical shear reinforcement.
[0014] Furthermore, the right ends of the upper group of PVC pipes are fixedly connected with filter discs.
[0015] Through the above scheme, by setting the filter disc, the purpose of filtering impurities can be achieved, and the blockage of the PVC pipe can be effectively avoided.
