Description

TECHNICAL FIELD

[0001] The utility model relates to a foundation pit construction technical field, concretely is a kind of water-collecting well sustained drainage device in foundation pit construction stage. BACKGROUND

[0002] Foundation pit is the soil pit that is excavated according to foundation design position, base elevation and foundation plane size. In the rain season, excessive precipitation or large amount of groundwater infiltration can easily lead to water accumulation in the foundation pit. If the accumulated water is not discharged in time, it will not only affect the construction period, but also erode the foundation and cause significant damage to the building quality. The bottom of the foundation pit is excavated with a drainage ditch around it, and some drainage ditches are equipped with water-collecting wells. The accumulated water in the foundation pit enters the water-collecting well through the drainage ditch. Currently, when draining the foundation pit, the water suction pipe is usually placed in the water-collecting well, and the accumulated water is pumped out by the water pump. Since there are mud and construction waste in the foundation pit, impurities flow into the water-collecting well with the accumulated water, and the water suction pipe is easily blocked when pumping water, which causes the pumping to stop. The staff needs to disassemble and clean the whole device, which cannot continue the drainage work during disassembly, resulting in a significant reduction in the efficiency of the drainage work.
