Automatic early warning system for precipitation engineering

Abstract

The invention discloses an automatic early warning system for precipitation engineering, which relates to the technical field of underground engineering risk control and solves the technical problem of real-time early warning. The system comprises a water level abnormality early warning unit and a power supply abnormality early warning unit, wherein the water level abnormality early warning unit comprises a water level abnormality monitoring device arranged in a precipitation well, a water level abnormality site early warning device arranged at the precipitation engineering site and a water level abnormality central early warning device arranged in a precipitation engineering control centre; the power supply abnormality early warning unit comprises a power supply abnormality site early warning device, a power supply abnormality remote early warning device, a telephone dialing apparatus and an alarm telephone; and a power supply abnormality signal output port of the power supply abnormality remote early warning device is connected with an alarm telephone through the telephone dialing apparatus. The automatic early warning system of the invention can send out an early warning signal in real time when the precipitation process is abnormal.

Description

technical field [0001] The invention relates to the technology of underground engineering risk control, in particular to the technology of an automatic early warning system for monitoring precipitation engineering in the construction process of underground engineering. Background technique [0002] During the construction of deep foundation pits, caissons, tunnels and other underground works in areas where the (micro) confined water level is shallow and the water head is high, it is often necessary to decompress the confined water. The decompression treatment of confined water generally adopts the method of deep well dewatering. This method uses pumping equipment to convert electrical energy into kinetic energy of groundwater seepage to form a descending funnel, thereby reducing the head pressure of the confined water in the foundation pit (or within a certain range) reduce. During a certain period of time during the construction period, the process of dewatering the confin...

AI Technical Summary

Problems solved by technology

The abnormality of the pumping equipment will directly cause the water level within the affected area of ​​the relevant pumping well to rise and exceed the safe water level; the abnormality of the power supply will directly cause the entire precipitation process to stop and the decompression to fail

In the current construction management process, it is mainly through the inspection of the personnel on duty to check whether the precipitation is running normally. Because the abnormalities of the pumping equipment and the power supply are generally sudden and unpredictable, this inspection and inspection is lagging behind. , which brings great hidden dangers to construction management and risk control
