Concrete retaining wall structure with energy dissipation and shock absorption functions

Abstract

The invention provides a concrete retaining wall structure with energy dissipation and shock absorption functions, and belongs to the field of urban underground road engineering and the technical field of public facilities. The structure comprises a concrete weight-adding strengthened pulling plate, a nodal shock absorption and energy dissipation device, a right-angled connecting plate, a tension-compression main energy dissipation steel plate, an auxiliary energy dissipation steel plate, a right-angled strengthened fixing steel plate, a strengthened pulling plate ring-shaped hooping, and a ring-shaped hooping connecting part. A vertical concrete plate is exposed to the outside of an original soil layer, and a vertical ring-shaped hooping is arranged near the edge of the interior of the vertical concrete plate. A horizontal ring-shaped hooping is arranged near the edge of the interior of a horizontal concrete plate. Two rows of longitudinal rebars are uniformly arranged at the inner side of the horizontal ring-shaped hooping. The concrete retaining wall structure with the energy dissipation and shock absorption functions has the beneficial effects that the integrity and stability of the retaining wall is improved, the problems of poor structural strength and high maintenance cost are avoided, the fracture or deformation failure of the retaining wall is avoided, and the structure has the strength and the ability of buffering and shock absorption, which forms a connection system with good shock absorption performance, so as to effectively support subgrade or hillside soil body and prevent soil deformation and instability.

Description

technical field [0001] The invention belongs to the field of urban underground road engineering and the technical field of municipal facilities, in particular to a concrete retaining wall structure with the function of energy consumption and shock absorption. 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 so...
