Hollow triangular arc-shaped retaining wall
Technical Field
The invention relates to the technical field of civil and architectural engineering, in particular to a hollow triangular arc-shaped retaining wall.
Background
The retaining wall is a building which supports roadbed filling or hillside soil body, prevents the filling or soil body from deforming and destabilizing and bears lateral pressure.
Retaining walls are widely used for roadbed filling, support of hillside rock and soil mass, landslide and emergency work of geological disasters. Retaining wall usually is equipped with steel reinforcement framework's concrete collar soil wall body, and the last distribution of concrete wall body has the drain pipe. The conventional construction mode of the existing common retaining wall is the piling of rock and soil mass and the concrete cast-in-place, which not only has large material consumption, complex construction and higher labor and material cost; and the quality is not easy to control, the construction period is longer, and the method is not easy to be applied to emergency work with time pressure.
