Abstract

The invention discloses a tray type retaining wall structure for weakening mutual influence of subgrade. The tray type retaining wall comprises a subgrade ballast bed, an existing subgrade body, an existing bottom foundation of subgrade and an existing subgrade slope, wherein a bottom plate is arranged on the bottom surface in the length direction of one side of the existing subgrade slope and a plurality of pile foundations are evenly arranged in the length direction of the lower end of the bottom plate at intervals. The retaining wall is formed by the vertical overlapping and fixed connection between a longitudinal baffle and one end of a horizontal baffle, and the other end of the horizontal baffle and the existing subgrade slope are overlapped. One side, away from the horizontal baffle, of the longitudinal baffle is provided with a newly-built subgrade body, the upper end of the horizontal baffle is provided with a leveling layer between lines, and the left and right sides of the leveling layer between lines are respectively consistent with the newly-built subgrade ballast bed and the existing subgrade ballast bed at the upper ends of the newly-built subgrade body and the existing subgrade body. The tray type retaining wall structure for weakening the mutual influence of the subgrade is high in bearing capacity, higher in earth retaining, broad in application range, convenient to construct, long in service life and better in economic and social benefit.

Description

technical field [0001] The invention relates to a retaining wall structure, in particular to a tray-type retaining wall structure for weakening mutual influence between roadbeds. Background technique [0002] With the rapid development of highway and railway construction, there are also more engineering projects for rebuilding and expanding various existing roads and adding new railway lines beside existing railway lines. The construction and construction process of these engineering projects will have a certain impact on the existing roads and railways. In addition, the self-weight and vehicle loads borne by newly-built roads and railways will also be transmitted and diffused through their own foundations to the depths of the foundation, causing additional stress and deformation on the subgrade base of existing lines, resulting in additional post-construction settlements, which will affect The performance of existing roads and railway subgrades. Common engineering measure...
