Embodiment Construction
[0020] In order to make those skilled in the art understand the core idea of the present invention more clearly, it will be described in detail below with reference to the accompanying drawings.
[0021] A steel sheet pile cofferdam support device disclosed by the invention, such as Figure 1~2 As shown, it includes the first wedge-shaped steel plate A, the second wedge-shaped steel plate B, the steel sheet pile and the H-shaped steel around the edge.
[0022] Wherein, the tip of the first wedge-shaped steel plate A faces downward, and the tip of the second wedge-shaped steel plate B faces upward. 25cm, and the thickness is a gradual section; the material of the first wedge-shaped steel plate A and the second wedge-shaped steel plate B can be Q235.
[0023] The first wedge-shaped steel plate A is closely attached to the second wedge-shaped steel plate B; the first wedge-shaped steel plate A is in close contact with the steel sheet pile, and the second wedge-shaped steel pla...

Abstract
The invention belongs to the technical field of civil engineering, and provides a steel sheet pile cofferdam supporting device. The supporting device comprises a first wedge-shaped steel plate A, a second wedge-shaped steel plate B, a steel sheet pile and edge-surrounding H-shaped steel, a steel plate hook is fixedly welded to the top end of the second wedge-shaped steel plate B, and the steel plate hook is welded to the inner edge of the edge-surrounding H-shaped steel in a clamped mode. A wedge-shaped block steel plate A and a wedge-shaped block steel plate B which are equal in size and section are designed, the wedge-shaped block steel plate B is clamped and welded to edge-surrounding H-shaped steel, the steel plate A is inversely inserted between the steel plate B and the steel plate pile, a gap between the steel plate pile and an edge-surrounding support is densely filled, so that it is ensured that the internal and external pressure difference acting on the steel plate pile can be effectively transmitted to an internal support, and deformation of the steel plate pile can be effectively restrained; and in addition, according to the different widths of gaps between the steel sheet pile and the edge-surrounding support, the embedding depth of the wedge-shaped block A inversely inserted between the steel plate B and the steel sheet pile can be adjusted up and down, operation is convenient, and applicability is high.
Description
technical field [0001] The invention relates to the technical field of civil engineering, in particular to a steel sheet pile cofferdam supporting device. Background technique [0002] The steel sheet pile cofferdam is inserted and driven. The geological soil structure in the same area is different, and there are certain errors in verticality. In addition, the inner support of the cofferdam is hoisted and lowered from top to bottom. In order to ensure that it can be lowered to the design elevation smoothly, the inner The dimension of the supporting cofferdam is about 5cm smaller than the planar dimension of the steel sheet pile cofferdam. [0003] However, after the inner support is lowered to the design elevation, there is a certain gap between the inner support edge and the steel sheet pile, so that the internal and external pressure difference acting on the steel sheet pile cannot be effectively transmitted to the inner support, resulting in easy deformation of the steel ...
