Leaping special-shaped buttress L-shaped retaining wall structure

Abstract

The invention discloses an L-shaped retaining wall structure of a cross-over type special-shaped counterfort. The structure comprises a wall body structure and a pile foundation, wherein the wall body structure comprises a wall panel, and a wall toe slab and a wall heel slab which are vertical to the wall panel, the wall toe slab is concave, counterforts are vertically arranged on the slab planes on the two sides of the wall toe slab, and wall top plates are arranged on the two counterforts. The retaining wall disclosed by the invention is designed to be in a counterfort structure; each wall toe plate is designed to be concave; the whole structure is one-time poured to form a whole body; not only can soil be retained, but also a man hole can be stridden; the influence of underground pipelines on the construction of a new pipeline can be reasonably avoided, not only can the construction of a newly-built railroad bed and running safety be ensured, but also the safety of the underground pipelines is ensured, as well as the problems of complex newly-built railways and underground pipelines, strained site space layout and construction safety are solved; and the retaining wall structure is safe and reliable, can be applied to a district with a complex site and a limited district, and can be used for solving the problems of the influences caused by strained lands, complex underground pipeline distribution and the like.

Description

technical field [0001] The invention relates to a retaining structure, in particular to an L-shaped retaining wall structure of a spanning special-shaped buttress, which is a roadbed type used in a site-limited section. Background technique [0002] The commonly used embankment retaining structure in railway engineering is gravity retaining wall, which has simple structure, convenient construction and relatively low cost. However, when the height of the gravity retaining wall is high, the requirements for the bearing capacity of the foundation are relatively high, and the section is also large. Another type of retaining structure is the buttress-type retaining wall. The toe plate of the buttress-type retaining wall can significantly increase the anti-overturning stability of the retaining wall and reduce the stress of the base. The tenon can increase the anti-skid performance of the structure. The buttress retaining wall is a light retaining structure with simple structure,...
