Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing.

[0027] The truss type retaining wall of the present invention has a structure such as figure 1 , figure 2 , image 3 As shown, it includes the upper truss structure, the cap beam 8 and the lower pile foundation. The pile foundation is a matrix structure composed of a compression pile foundation 9 on the outside, an intermediate pile foundation 10 on the middle and a tension pile foundation 11 on the inside. The upper truss structure is connected to the lower pile foundation through the cap beam 8, and the lower pile foundation is embedded in the rock layer or soil layer at the bottom of the slope. The upper truss structure, the lower cap, and the pile foundation are arranged at a certain distance, and the transverse connecting beam 7, the soil retaining plate 5, the top beam 12, the roof 13, the cap beam 8, and the cap bottom plate 15 are connected to form a soil retain...

Abstract

The invention discloses a truss type retaining wall. The upper end of a lower part pile foundation is connected with an upper part truss structure through a bearing platform beam; the upper part truss structure comprises upper chord stand columns, lower chord stand columns, horizontal web girders, inclined web girders, transverse connecting beams and retaining plates; wherein the lower chord stand columns are connected through the transverse connecting beams to form a grid structure; each upper chord stand column is connected with the corresponding lower chord stand column through a plurality of horizontal web girders and a plurality of inclined web girders; every two adjacent upper chord stand columns are connected through the retaining plates to form an integrated retaining wall. The invention relates to a vertically placed cantilever truss structure system, which mainly utilizes the rationality and the stability of stress of truss triangular structure arrangement to improve the bearing capability and the lateral migration resisting ability of a retaining structure. Meanwhile, the overturning moment of a vertical truss retaining structure is balanced by utilizing the weight G of anti-pressure soil on the upper part of the bearing platform. According to the truss type retaining wall provided by the invention, the material intensity can be fully utilized, and the material utilization ratio is improved, and the construction cost of the foundation is reduced.

Description

technical field [0001] The invention relates to the structural improvement of retaining walls, in particular to a truss-type retaining wall for supporting and retaining high fill slope engineering, and belongs to the field of slope engineering in civil engineering. 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 roc...
