Civil construction foundation pit drainage structure and construction method thereof

Abstract

The invention relates to a civil construction foundation pit drainage structure and belongs to the technical field of civil construction. The civil construction foundation pit drainage structure comprises a foundation pit body, water collecting troughs are formed in the four corners of the foundation pit body, water diversion gutters are formed in the positions, at the peripheral edges of the foundation pit body, between the adjacent water collecting troughs, each water collecting trough is internally provided with a water pump, a water pumping pipe extending out of the foundation pit body isarranged at the output end of each water pump, a plurality of supporting plates are arranged on the side walls of the foundation pit body in an abutting connection mode, the height of the supporting plates is greater than the height of the side walls of the foundation pit body, each supporting plate is internally provided with a cavity, a plurality of water inlet holes communicating with the cavities are formed in the surfaces, facing the side walls of the foundation pit body, of the supporting plates, a plurality of drainage pipes are obliquely arranged on the surfaces, deviating from the foundation pit body and located on the lower parts of the supporting plates, of the supporting plates, and the ends, away from the supporting plates, of the drainage pipes are arranged towards the waterdiversion gutters. Accumulated water in the side walls of the foundation pit body can be drained into the water collecting troughs, and the situation that the side walls of the foundation pit body arecollapsed due to the excessive accumulated water is prevented.

Description

technical field [0001] The invention relates to the technical field of civil construction, in particular to a foundation pit drainage structure for civil construction and a construction method thereof. Background technique [0002] Foundation pit dewatering means that when the foundation pit is excavated, the groundwater level is higher than the excavation bottom, and the groundwater will continuously seep into the pit. Dewatering work due to pit bottom piping and foundation bearing capacity decline. The methods of foundation pit dewatering mainly include: open ditch plus water collection well dewatering, light well point dewatering, jet well point dewatering, electroosmotic well point dewatering, deep well well point dewatering, etc. [0003] The Chinese patent whose authorized notification number is CN207974129U discloses a foundation pit energy-saving drainage system, including a water collection well, a water suction pipe, a vacuum pump, a siphon controller and a water ...

AI Technical Summary

Problems solved by technology

But its disadvantage is that when it rains, the rainwater will infiltrate into the side wall of the foundation pit, which will cause water accumulation in the side wall of the foundation pit, reduce the strength of the side wall of the foundation pit, and in severe cases will cause the side wall of the foundation pit to appear. collapse phenomenon
