Abstract

The invention provides a multi-step precast concrete retaining wall, and belongs to the technical field of support construction. The multi-step precast concrete retaining wall comprises a multi-step precast concrete bottom plate, a precast concrete retaining wall body, a concrete tie beam, tie steel bars and nuts, wherein an upper step base of the precast concrete retaining wall body is arranged on a wall body base of the multi-step precast concrete bottom plate, and a lower step base of the precast concrete retaining wall body is clamped on the outer side of the wall body base of the multi-step precast concrete bottom plate; and the tie steel bars are connected with the soil filling side of the precast concrete retaining wall body, and the other ends of the tie steel bars penetrate through a hole channel of the concrete tie beam and are locked through the nuts. The anchoring performance, integrity and stability of the concrete retaining wall can be improved, multi-step bayonets are adopted, sliding and overturning are effectively prevented, and the bearing capacity of the wall is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of support construction, in particular to a multi-step prefabricated concrete retaining wall. Background technique [0002] Slope engineering is in a particularly important position in the whole large civil engineering because of the large amount of slope engineering, high technical difficulty and high accident rate. The object of slope engineering is rock or soil. Rock and soil are naturally generated and cannot be artificially manufactured. The characteristics are: properties vary from place to place and from time to time; human understanding cannot be exhaustive; mechanical parameters cannot be provided accurately; design level It varies from person to person. The existence of these characteristics has brought great difficulties to the construction of the project. The result is: improper grasp of rock and soil mass, high accident rate (it is understood that in construction projects, the accident rate of ...
