Anti-grouting-pipe-explosion monitoring and early warning system and using method thereof

Abstract

The invention relates to an anti-grouting-pipe-explosion monitoring and early warning system and a using method thereof. The system comprises a first pressure measuring device which is arranged at the grout outlet of a grouting pump and used for measuring a first pressure value of grout at the outlet of the grouting pump, a second pressure measuring device which is arranged at the inlet of a grouting pipe and used for measuring a second pressure value of grout at the inlet of the grouting pipe, and an early warning device which has a shell for accommodating an early warning unit, wherein the first pressure measuring device and the second pressure measuring device are pressure gauges, each pressure gauge is equipped with a threshold input device, and the early warning device sounds an alarm when the first pressure value or the second pressure value is greater than a first threshold.

Description

technical field [0001] The patent belongs to the technical field of grouting construction, and specifically relates to a monitoring and early warning system for preventing grouting burst pipes and its application method. Background technique [0002] In the construction of underground engineering, grouting is a powerful tool that can improve the geological properties of engineering. It plays the role of anti-seepage, water blocking, consolidation, control of surface subsidence, and improvement of surrounding rock strength. [0003] The grouting process is relatively complicated, and sometimes the grouting pipe is blocked, grouting cannot be performed, or even the grouting pipe is blocked due to reasons such as too long grouting stop time, too high sand content in the grout, or the accumulation of grout in the tee part of the grouting pipe. Bursting construction accidents will seriously affect the construction quality and construction progress. In view of this phenomenon, al...

AI Technical Summary

Problems solved by technology

[0003]The grouting process is relatively complicated, and sometimes it may be caused by too long stop grouting time, too high sand content in the grout, or the accumulation of grout in the tee part of the grout pipe, etc. It will lead to blockage of grouting pipes, failure of grouting, and even construction accidents of grouting pipe bursting, which will seriously affect construction quality and construction progress

In view of this phenomenon, although there are corresponding preventive measures and treatment methods, the actual construction conditions are particular and complex. If there is no real-time monitoring and early warning system for slurry plugging and pipe bursting, it will be difficult to take corresponding measures quickly to prevent Eliminate hidden dangers of construction accidents
