Abstract

The invention discloses a support structure for a foundation pit of a comprehensive pipe gallery and a construction method thereof, and relates to the technical field of foundation pit support, including a plurality of steel sheet piles arranged on opposite sides of the foundation pit and a plurality of steel sheet piles arranged at intervals along the length direction of the foundation pit The supporting assembly includes two supporting arms, a rotating part, two fixing plates, two fixing parts for fixing the corresponding supporting arms, and two connecting pieces respectively arranged on the corresponding supporting arms, and the two supporting arms are connected with The rotating part is rotatably connected, and the fixed plate includes a horizontal plate and a vertical plate connected to the horizontal plate. The end of the support arm away from the rotating part is rotatably connected to the fixed plate. The horizontal plate is pressed against the upper side of the steel pipe pile, and the vertical plate is away from the side of the support arm It is pressed against the side of the steel pipe pile, the connecting piece is arranged on the support arm, and the other ends of the two connecting pieces in the same support assembly are connected with the same counterweight. The application has the effects of effectively shortening the construction period and reducing the support cost of the foundation pit.

Description

technical field [0001] The invention relates to the field of foundation pit support, in particular to a support structure and a construction method for a comprehensive pipe gallery foundation pit. Background technique [0002] The comprehensive pipeline corridor refers to a tunnel space built underground in the city, which integrates various engineering pipelines such as electricity and gas into one underground urban pipeline comprehensive corridor. [0003] When carrying out the construction of the comprehensive pipe gallery, it is first necessary to insert the steel sheet piles into the designated position on the ground according to the requirements of the construction drawings, and arrange them in two rows relative to each other. pit, and then construct steel purlins and steel supports on the opposite sides of the steel sheet piles, and the two ends of the steel supports are respectively lapped on the steel purlins on both sides. [0004] On the basis of guaranteed quali...
