High cantilever combined retaining wall structure

Abstract

The invention relates to a high cantilever combination retaining wall structure which has good integrity, strong structure strength and good slope contracting efficiency so as to solve the slope contracting problem of a high embankment. The high cantilever combination retaining wall structure comprises a cantilever retaining wall (1) arranged at the outer side of an embankment slope, strengthening piles (2) which are longitudinally arranged at intervals along a line, supporting connecting walls (3) which are arranged between the cantilever retaining wall (1) and the strengthening piles (2) and are fixedly connected with the cantilever retaining wall (1) and the strengthening piles (2) and a filter layer (4) which is fixedly arranged on the inner side surface of the cantilever retaining wall (1).

Description

technical field [0001] The invention relates to high-fill embankment slope closure structures for railways, highways, municipal engineering, etc., and in particular to a high-cantilever combined retaining wall structure. Background technique [0002] In the construction of roads and municipal projects in our country, there are usually requirements for slope closure of embankments in special sections, especially for railway stations, which require slope closure of high-fill embankments due to the needs of site, landscape and special projects. Traditional shoulder walls, embankment pile-slab walls, and pile foundation joists have problems such as limited appearance requirements, limited slope height, large cantilever height deformation, and special engineering structure forces that cannot meet the requirements. The new cantilever retaining wall and buttress The appearance of the cantilever retaining wall is better, but the same as the structure of the traditional slope closure...

AI Technical Summary

Problems solved by technology

Traditional shoulder walls, embankment pile-slab walls, and pile foundation joists have problems such as limited appearance requirements, limited slope height, large cantilever height deformation, and special engineering structure forces that cannot meet the requirements. The new cantilever retaining wall and buttress The appearance of the cantilever retaining wall is better, but the same as the structure of the traditional slope closure, the height of the slope closure and the use conditions are limited. For example, the specification requires that the cantilever retaining wall should not exceed 6m, and the buttress retaining wall should not be greater than 10m, and Restricted use in bad geology and high-intensity earthquake areas
