Fabricated steel-concrete arch plate retaining wall

Abstract

The invention discloses a fabricated steel-concrete arch plate retaining wall. The fabricated steel-concrete arch plate retaining wall comprises concrete arch plates, a plurality of pieces of H-shapedsteel, steel rings, reinforcing steel bars, channel steel, original soil, filling soil, nuts and anchor rods; the multiple layers of concrete arch plates are arranged on the original soil in the vertical direction, and of the multiple concrete arch plates are arranged on each layer; the multiple pieces of H-shaped steel are vertically arranged between flat end plates of every two adjacent concrete arch plates on the left side and the right side, the bottom ends of the H-shaped steel are inserted into original soil by 200-500 mm, and the flat end plates of the concrete arch plates are insertedinto notches between flanges of the H-shaped steel; and a space between a wavy retaining wall formed by the concrete arch plates and the H-shaped steel and original soil is filled with the filling soil, arches of arc-shaped concrete arch plates of the concrete arch plates are bent towards the soil filling direction, the steel rings are welded to the upper portions of the soil filling sides of theH-shaped steel, the top ends of the reinforcing steel bars are connected with the steel rings, and the bottom ends of the reinforcing steel bars are connected with the channel steel through the nuts.The bearing capacity of a wall body can be remarkably improved, the safety performance is remarkably improved, the cost is low, and the engineering quality is easily guaranteed.

Description

technical field [0001] The invention relates to a retaining wall, in particular to an assembled steel concrete arch plate 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 slopes accounts for abou...
