Foundation pit advanced grouting expanding steel pipe inclined strut supporting construction structure

Abstract

The utility model discloses a foundation pit advanced grouting expanding steel pipe inclined strut support construction structure which comprises a support beam, a steel pipe inclined strut, a steel pipe inclined strut and a steel pipe inclined strut. The bottom of the support beam is vertically provided with a curtain wall. The steel pipe piles are obliquely arranged, and the upper ends of the steel pipe piles are connected with the supporting beams; the steel pipe pile comprises a plurality of pipe joints arranged in sequence, and a supporting assembly is arranged between every two adjacent pipe joints. The supporting assembly comprises a supporting pipe, supporting sleeves, pull rods and a steel belt sleeve, the supporting pipe is arranged between two adjacent pipe joints, the two supporting sleeves are arranged at the ends of the supporting pipe and the corresponding pipe joints in a sleeving mode respectively, and the multiple pull rods are arranged between the two supporting sleeves at intervals in the circumferential direction of the supporting pipe; the two ends of the pull rod are slidably connected with the two supporting sleeves respectively, and the steel belt sleeve is arranged between the two supporting sleeves and located on the outer side of the pull rod. When static load test operation is prepared, only the steel belt sleeve needs to be cut, the cutting workload is small, the time consumed for preparation operation can be effectively shortened, and therefore the detection efficiency can be improved.
