Abstract

The invention discloses a foundation pit supporting pile top crown beam structure and a construction method thereof, and relates to the technical field of foundation pit supporting pile top crown beamstructures. In order to facilitate construction, the top crown beam structure specifically comprises a first frame body and a second frame body, cross beams distributed at equal intervals are arranged on the first frame body and the second frame body, assembly inserting holes distributed evenly are formed in the outer walls of the bottoms of the first frame body and the second frame body, a firstfixing rod and a second fixing rod are inserted into the assembly inserting holes respectively, and the second fixing rods correspond to the cross beams in position. By arranging the first frame body, the second frame body and other structures, the first frame body and the second frame body can be used as a main frame for supporting during installation, the structural firmness is guaranteed, a large amount of steel bar erecting time is saved, and the construction period is effectively shortened; and by arranging connecting rods, connecting sleeves and other structures, a user can disassembleand assemble according to the required height, so that multi-layer erection is achieved, and the flexibility is improved.

Description

technical field [0001] The invention relates to the technical field of foundation pit support pile crown beam structure, in particular to a foundation pit support pile crown beam structure and a construction method thereof. Background technique [0002] The crown beam of foundation pit supporting piles is a continuous beam arranged on the top of the supporting structure around the foundation pit; its function is to connect all the pile foundations together to prevent the top edge of the foundation pit from collapsing. At present, the general foundation pit supports The crown beams of protective piles are mostly cast-in-place operations. Although they can meet certain usage requirements, the process takes time and the construction costs are high, and a lot of manpower and material resources are wasted. [0003] After searching, the Chinese patent application number is CN201822122869.X, which discloses a hat-shaped composite steel sheet pile top-crown beam structure for founda...
