Embodiment 1

[0040] The embodiment of the present application discloses a support structure for a deep foundation pit. refer to figure 1 and figure 2 , deep foundation pit support structure. It includes steel sheet piles 1 arranged continuously along the inner wall of the foundation pit, and each steel sheet pile 1 forms a closed-loop retaining wall 9 together. The retaining wall 9 has a square structure as a whole. The four inner surfaces of the retaining wall 9 A support beam 2 is provided, and a plurality of mutually parallel cross-stay beams 3 are jointly erected between two opposite support beams 2, wherein the cross-stay beams 3 of different orientations are arranged vertically in dislocation; the support beams 2 The upper surface is fixedly connected with a plurality of push plates 21 corresponding to the ends of the cross-bracing beams 3, and the cross-bracing beams 3 are used to force the opposing push plates 21 to move away from each other.

[0041] refer to figure 1 , the su...

Embodiment 2

[0055] refer to Figure 5 and Figure 6 The difference between this embodiment and Embodiment 1 is that: a clamping assembly 8 is connected between the two ends of the cross brace beam 3 and the two opposite support beams 2, and the clamping assembly 8 includes a first clamping block 81, The second clamping block 82 and the sleeve 83;

[0056] The sleeve 83 is sleeved and connected to the end of the first cross brace 3, and one end of the sleeve 83 is closed, and the first clamping block 81 is fixedly connected to the closed end of the sleeve 83, and a plurality of pads are placed inside the sleeve 83. Plates 84, each backing plate 84 is dislocated along the length direction of the cross brace 3, and the backing plate 84 is located between the end faces of the second clamping block 82 of the cross brace 3; the second clamping block 82 is fixedly connected with the push plate 21, The first clamping block 81 and the second clamping block 82 are dislocated along the length dire...

Abstract

The invention discloses a deep foundation pit supporting structure which comprises steel sheet piles continuously arranged along the inner wall of a foundation pit, the steel sheet piles jointly form a retaining wall of a closed-loop structure, the retaining wall is provided with a plurality of hanging pieces in the circumferential direction, each hanging piece comprises a vertical plate, the upper edge of each vertical plate is provided with a hanging part, and the lower edge of each vertical plate is provided with a hooking part. The hanging pieces are connected with the upper edges of the steel sheet piles in a hanging mode through the hanging parts, supporting beams are jointly erected on the hanging pieces located on the same side in the retaining wall through the hooking parts, a transverse supporting beam is jointly erected between every two opposite supporting beams, and push plates are fixedly connected to the upper surfaces of the supporting beams. And the transverse supporting beams are used for forcing the opposite push plates to generate a moving trend of being far away from each other. The transverse supporting beams playing a transverse supporting role are erected through the supporting beams, the transverse supporting beams are erected through the hanging pieces, welding operation is not needed, and follow-up disassembly is facilitated.

Description

technical field [0001] The application relates to the field of building technology, in particular to a deep foundation pit support structure. Background technique [0002] A foundation pit is an earth pit excavated at the foundation design position according to the basement elevation and foundation plane size. A deep foundation pit refers to an excavation depth of more than 5 meters (including 5 meters), or a depth of less than 5 meters, but the geological conditions and the surrounding environment and underground pipelines are particularly complex projects. The foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit, and the support, reinforcement and protection measures adopted for the side wall of the foundation pit and the surrounding environment. [0003] There are various forms of foundation pit support, and different foundation pit forms have their own characteristics. The choice o...
