Embodiment 1

[0043] A foundation pit supporting structure. refer to figure 1 , the foundation pit support structure includes support bars 2 arranged on the inner wall of the foundation pit 1, the support bars 2 are provided with a plurality of support bars 2 intersecting each other, and the support bars 2 can be set as steel bars and between the bars Fix it by welding between them, and then spray cement on the outside of the support rib 2, so as to support the inner wall of the foundation pit 1.

[0044] refer to figure 2 and image 3 , in order to improve the stability of the cooperation between the support rib 2 and the inner wall of the foundation pit 1, a chute 11 is provided on the inner wall of the foundation pit 1, and there are multiple groups of chute 11, each group includes a plurality of chute 11, each group The chute 11 is arranged at intervals horizontally along the length direction of the inner wall side of the foundation pit 1, and the end of the chute 11 away from the i...

Embodiment 2

[0055] A construction method for a foundation pit support structure, comprising the steps of:

[0056] Step 1: On the inner wall of the foundation pit 1, set up chute 11 along the direction toward the ground or away from the ground, and set up reinforcement groove 12 in the horizontal direction, and make the groove of reinforcement bar 4 communicate with the chute 11.

[0057] Step 2: place the diagonal brace 3 in the chute 11 , and then place the reinforcing rod 4 in the reinforcing groove 12 .

[0058] Step 3: Insert the end of the reinforcing rod 4 into the connecting sleeve 32 and turn the reinforcing rod 4 to thread the reinforcing rod 4 and the connecting sleeve 32 .

[0059] Step 4: Insert the stabilizing rod 42 at the edge of the foundation pit 1 close to the ground, and connect the stabilizing rod 42 with the reinforcing rod 4 through the slot 41 .

[0060] Fifth step: Embedding the water retaining plate 9 obliquely at the edge of the opening of the foundation pit 1 ...

Abstract

The invention relates to the technical field of foundation pit supporting, and particularly relates to a foundation pit supporting structure and a construction method. The foundation pit supporting structure comprises a plurality of supporting ribs arranged in a foundation pit in a crossed mode; concrete is poured on the supporting ribs; inclined grooves and reinforcing grooves are formed in the inner wall of the foundation pit; the inclined grooves communicate with the reinforcing grooves; the ends, deviating from the supporting ribs, of the inclined grooves are obliquely arranged in the vertical direction; inclined supporting rods are arranged in the inclined grooves; reinforcing rods are arranged in the reinforcing grooves; connecting sleeves used for being connected with the reinforcing rods are arranged on the inclined supporting rods; clamping pieces are arranged on the reinforcing rods and the inclined supporting rods; and the reinforcing rods and the inclined supporting rods are connected with the supporting ribs through the clamping pieces. The foundation pit supporting structure has the effect of reducing the occupied construction space.

Description

technical field [0001] The present application relates to the technical field of foundation pit support, in particular to a foundation pit support structure and a construction method. Background technique [0002] The foundation pit support is to protect the safety of the underground structure construction and the surrounding environment of the foundation pit, and the support, reinforcement and protection measures are adopted for the side wall of the foundation pit and the surrounding environment. [0003] In the related art, the foundation pit support system includes a deep foundation pit system, a water stop pile and a support pile are arranged in the deep foundation pit body, and a support structure is arranged on one side of the support pile, and the support structure includes a diagonal brace and a support pile. The vertical support part, the vertical support part is in contact with the inner wall of the foundation pit, one end of the diagonal support part is in contact...
