Abstract

The invention provides a foundation pit dewatering system which comprises a water collecting well, a cover plate, a water depth measuring rod, a water depth detector, a water pumping control device and a water pumping device. The cover plate is located in the water collecting well and floats on the water surface where water seeps in the water collecting well; the water depth measuring rod penetrates through the cover plate and is vertically fixed to the bottom of the water collecting well; the water depth detector is located on the upper side of the cover plate and is in sliding connection with the water depth measuring rod; the water pumping control device is connected with the water depth detector; the water pumping device is connected with the water pumping control device. Sliding of the water depth detector is achieved through buoyancy of water seepage in the water collecting well, so that the water depth detector can judge the water depth condition in real time according to the water depth scale of the water depth measuring rod, a starting signal is generated when the water seepage surface rises above the high water level scale, and a stopping signal is generated when the water seepage surface falls below the low water level scale; therefore, by means of signal linkage of the water depth detector and the water pumping control device, automatic starting and stopping of foundation pit drainage operation are achieved.

Description

technical field

[0001] The invention relates to the technical field of building construction, in particular to a foundation pit dewatering system. 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 continue to seep into the pit. Dewatering work due to pit bottom piping and foundation bearing capacity decline. The water collection well is a common structure in the precipitation of foundation pits to collect seepage water. In order to prevent the seepage from overflowing the water collection well, the seepage in the water collection well needs to be drained away by the water pump in time. At present, the water level in the water collection well is mostly observed by the operator with the naked eye, and the drainage operation also requires special personnel to handle it. However, if the pumping is not timely due to personnel negligence or...
