Device for controlling engineering precipitation

Abstract

The invention discloses a device for controlling engineering precipitation, which relates to the technical field of underground engineering risk control and aims to solve the technical problem of low risk control and defense capability. The system comprises a main power supply, a standby power supply, a main pumping well, a standby pumping well, an automatic transfer switch (ATS) intelligent conversion and shunt delay power supply device and a standby intelligent pumping well control device, wherein the standby intelligent pumping well control device comprises an intelligent controller, a water level abnormity monitor and a starting box; the water level abnormity monitor feeds a precipitation water level back to the intelligent controller in real time; the intelligent controller automatically starts or stops pumping equipment in the standby pumping well through the starting box; and an automatic judgment module is arranged the ATS intelligent conversion and shunt delay power supply device and is used for automatically switching precipitation power utilization and supply power to each pumping equipment. The system provided by the invention can lower the risk probability and harmfulness during precipitation operation.

Description

technical field [0001] The invention relates to the technology of underground engineering risk control, in particular to the technology of a device for controlling engineering dewatering used for deep foundation pit engineering dewatering risk control and emergency treatment. Background technique [0002] During the construction of high-rise building foundations and underground structures, most of them need to excavate deep foundation pits. When excavating foundation pits in areas with high groundwater levels, on the one hand, it is necessary to ensure that the excavation surface of the foundation pit is dry, so as to facilitate workers and mechanical operations. The treatment method of setting up dewatering wells in the foundation pit is to improve the strength of the soil in the pit; For foundation pit bottom surge and pit bottom uplift, it is necessary to arrange relief wells for decompression and dewatering according to specific needs; [0003] In the process of decomp...

AI Technical Summary

Problems solved by technology

[0003] In the process of decompression and precipitation, there are many risks in the operation and management of precipitation, among which the main source of risk is the risk caused by abnormal power supply and abnormal equipment

In the prior art, the risk control measures adopted for the risks caused by abnormal power supply and equipment abnormality are to set up backup power supply and backup dewatering well, and manually switch to the backup power supply or backup dewatering well when the power supply or equipment is abnormal (Especially nighttime construction management) The risk control efficiency is low, and there is a defect in preventing and lagging treatment, so the risk control and resistance ability is poor, and the risk probability and its harmfulness in precipitation operation are high
