Embodiment

[0038] Embodiment: a foundation pit drainage device, including a drainage pump 1 and a water collection well 3, the drainage pump 1 is arranged on one side of the water collection well 3, and the water-drawing end of the drainage pump 1 is movably connected with an opening facing the sewage in the water collection well 3 The elbow 2 above the liquid level, the outer end of the elbow 2 is movably connected to a drainer 4 that can rise and fall with the rise and fall of the sewage liquid level in the water collecting well 3, and the drainer 4 includes a counterweight 41 floating on the liquid surface, The sewage enters from the bottom of the counterweight 41 and can filter the sewage. The water inlet end of the elbow 2 is set above the counterweight 41 and rises and falls in the water collecting well 3 with the displacement of the counterweight 41, and the The sewage filtered by the counterweight 41 is pumped out of the water collecting well 3 through the drainage pump 1 .

Abstract

The invention relates to the technical field of hydraulic engineering construction, in particular to a foundation pit drainage device and a using method thereof.The foundation pit drainage device comprises a drainage pump and a water collecting well, the drainage pump is arranged on one side of the water collecting well, and the water drawing end of the drainage pump is movably connected with a bent pipe with an opening facing the position above the sewage liquid level in the water collecting well. One end of the drainage pump is connected with the bent pipe capable of moving up and down, meanwhile, the pipe opening of the bent pipe is arranged upwards, turbid impurities at the bottom of the water collecting well are prevented from being sucked into the pump pipe through suction force, and the drainage device capable of floating on the water surface in the drainage well is arranged on the outer side of the bent pipe; the bent pipe is driven to move along with ascending or descending of the liquid level, impurities with large sizes in water can be isolated through the base plate at the bottom end of the drainer, sewage is filtered to a certain degree, and the possibility that a pump pipe is blocked is reduced.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering construction, in particular to a foundation pit drainage device and a method for using the same. Background technique [0002] The foundation pit refers to the space below the ground excavated for the construction of the foundation and basement of buildings (including structures). Affects the firmness of the foundation, and even affects the firmness of the completed building. At present, there are usually three methods of drainage in the foundation pit, and there are three methods of drainage in the foundation pit; they are open ditch drainage, well point precipitation and blind ditch. Drainage, open ditch drainage refers to the drainage ditch system composed of excavated open trenches and its supporting buildings. Well point dewatering is to bury a certain number of water filter pipes (wells) around the foundation pit before the excavation of the foundation pit. The method ...
