Drilling grouting run-out alarm device and use method thereof

Abstract

The invention discloses a drilling grouting run-out alarm device and a use method thereof, and solves the problems that in the prior art, manual patrol is needed for judging whether run-out occurs ornot, so that the detection cost is relatively high and the detection is non-timely. The device has the beneficial effects that the monitoring efficiency is high, and the waste of slurry materials is effectively reduced. The scheme is as follows: the drilling grouting run-out alarm device comprises a photoresistance sensor which can be arranged at a groundwater bursting point, an alarm device, an illumination device which can be arranged at a side part of the photoresistance sensor to assist in illumination, and a controller which is separately connected with the photoresistance sensor and theillumination device; and the photoresistance sensor and the alarm device are arranged in parallel.

Description

technical field [0001] The invention relates to the field of drilling and grouting in underground engineering, in particular to a drilling and grouting alarm device and a use method thereof. Background technique [0002] In recent years, with the continuous development and utilization of underground space resources, the problem of water inrush during underground engineering construction has become increasingly prominent. Currently, underground engineering often uses drilling and grouting to block water and strengthen rock and soil. During the drilling and grouting process, Pulp phenomenon occurs. Once the phenomenon of grouting occurs, improper disposal or slow disposal will result in the loss of grouting materials. It is very important and necessary to find out the grout in time during the grouting water blocking process. Therefore, strict grout monitoring should be carried out in the grouting project. [0003] At present, the inventor has found that there are the followi...

AI Technical Summary

Problems solved by technology

[0003] At present, the inventor has found that there are the following problems in the monitoring of grouting and grouting in underground engineering: a. The monitoring intelligence is low, and most of them use fixed-point or manual inspections, and the monitoring cost is relatively high, and the real-time grouting status information of a certain point cannot be obtained in time ; b. The existing detection methods relying on manual inspection have limited coverage of the monitoring distance and range of slurry monitoring, and are greatly affected by light and complex environmental factors inside the underground project. The monitoring distance and range coverage is lower, and the timeliness is poor. It is easy to miss the golden time for accident rescue; c. During the construction of underground engineering, due to the complex geological conditions, many slurry leakage points cannot be manually monitored
