Foundation pit dewatering system
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.
本发明公开了一种基坑降水系统，包括：集水井、盖板、水深测量杆、水深检测器、抽水控制装置及抽水装置。其中，盖板位于集水井的内部，且漂浮在集水井内部渗水的水面上；水深测量杆贯穿盖板，并竖直固定于集水井的底部；水深检测器位于盖板的上侧，且与水深测量杆滑动连接；抽水控制装置与水深检测器连接；抽水装置与抽水控制装置连接。本发明利用集水井内部渗水的浮力实现水深检测器的滑动，使水深检测器能够根据水深测量杆的水深刻度实时判断水深情况，并在渗水水面上涨到高水位刻度以上时产生启动信号，在渗水水面下降到低水位刻度以下时产生停机信号，从而利用水深检测器与抽水控制装置的信号联动，实现基坑排水作业的自动启停。
