Abstract

The invention relates to a foundation pit structure. The foundation pit structure comprises a foundation pit, wherein a supporting structure is mounted on the inner side wall of the foundation pit; the supporting structure comprises a supporting plate; the supporting plate is mounted at the peripheral side in the foundation pit; one side, away from the center of the foundation pit, of the supporting plate abuts against the inner side wall of the foundation pit; a water draining tube is arranged on the supporting plate; the water draining tube is hollow; the water draining tube is in threaded connection in the supporting plate in an inclined upward mode; the water inlet end of the water draining tube is inserted into the side wall of the foundation pit; the water draining tube extends to the peripheral surface of one side, towards the foundation pit, of the supporting plate, and is equipped with a locking part; a water draining ditch is formed in a position, below the water outlet end of the water draining tube, of the pit bottom of the foundation pit; a water pumping assembly for pumping out water in the water draining ditch is arranged in the foundation pit; and an isolating device is arranged at the peripheral side of the top surface of the side wall of the foundation pit. According to the scheme adopted by the invention, the water draining tube and the isolating device are arranged, so that the problems that a retaining baffle is low in recycling rate and water is easily accumulated on the side wall of the foundation pit can be effectively solved, and therefore, safety and stability of foundation pit construction are guaranteed.

Description

technical field [0001] The present application relates to the field of building construction, in particular to a foundation pit structure and construction technology. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base level and foundation plane size. In engineering construction, foundation pit excavation often encounters precipitation in the foundation pit. The groundwater level is higher than the bottom of the excavation, and groundwater will continuously seep into the pit. In order to ensure that the foundation pit can be constructed under dry conditions, and prevent slope instability and foundation quicksand , pit bottom uplift, pit bottom piping and foundation bearing capacity drop, it is necessary to carry out dewatering work in the foundation pit. [0003] At present, the measures for foundation pit dewatering control mainly include open ditch plus water collection well dewatering, light w...
