a retaining wall

Abstract

The invention relates to a retaining wall, in particular to a middle corridor type retaining wall. The retaining wall comprises a front wall, base plates, upright columns and an unloading platform, wherein the bottom side of the front wall is fixedly connected with the base plates, the unloading platform is horizontally connected with one side face of the upper part of the front wall, the upright columns are vertically arranged on the base plates, and the upper ends of the upright columns are connected with the lower side face of the unloading platform. According to the retaining wall disclosed by the invention, by utilizing the unloading platform, loads of the upper part are conveyed onto the base plates through the upright columns, and the soil body below a platform does not bear the loads of the upper part, so that the horizontal soil pressure to the front wall is reduced, even the effect that the horizontal soil pressure is reduced by 25% can be realized; therefore the anti-sliding and anti-collapsing performances of the retaining wall are improved, the unbalance loading degree of the structure of the retaining wall is reduced, and the stress situations of the foundation and the structure of the retaining wall are improved. According to the retaining wall disclosed by the invention, the foundation treatment is not needed, the volume of earthwork is reduced, the problems of the engineering structure are solved, and the cost of the engineering is also reduced; the damage by quarrying the mountain to the environment is avoided.

Description

technical field [0001] The invention relates to the field of retaining walls, in particular to a retaining wall with an inner corridor structure. Background technique [0002] In the construction of water transportation and water conservancy, etc., it is necessary to set up retaining walls to realize the use function or the safety of the slope structure, or to save space. Traditional retaining wall structures such as figure 1 As shown, in order to achieve overall anti-sliding and anti-tilting stability, the bottom plate D is usually widened to increase resistance, or block stone prisms with large internal friction angles are used as backfilling behind the wall to reduce the horizontal earth pressure behind the wall. On the one hand, widening the floor will increase the engineering volume of the retaining wall itself, and will also increase the engineering volume of the excavation of the working face and backfilling behind the wall, which is less economical; using block ston...

AI Technical Summary

Problems solved by technology

On the one hand, widening the floor will increase the engineering volume of the retaining wall itself, and will also increase the engineering volume of the excavation of the working face and backfilling behind the wall, which is less economical; using block stone prisms as backfilling behind the wall requires mining rocks, which are harmful to the environment

In addition, due to the partial load of the structure in the traditional retaining wall structure, the stress difference between the front toe and the back heel of the floor is very large. When the stress of the front toe exceeds the bearing capacity of the foundation, foundation treatment is required
