A grouting control method, device and system

Abstract

The present invention relates to the technical field of drilling rig grouting, and specifically discloses a grouting control method, which includes: obtaining the current formation cement slurry pressure data in real time; comparing the current formation cement slurry pressure data with a preset cement slurry pressure value And obtain the comparison result; generate a control signal according to the comparison result, and the control signal is used to control the actuator to perform cement slurry injection, suck out excess cement slurry or stop cement slurry injection. The invention also discloses a grouting control device and system. The grouting control method provided by the invention can ensure the smooth progress of grouting, realize intelligent control, and avoid the problems of insufficient grouting or excessive pressure grouting in the prior art.

Description

technical field [0001] The invention relates to the technical field of drilling rig grouting, in particular to a grouting control method, a grouting control device and a grouting control system including the grouting control device. Background technique [0002] The development of the field of foundation engineering has led to a huge demand for foundation engineering construction. In the field of foundation engineering construction, ground grouting construction is often involved. High-pressure grouting construction is widely used because of its high efficiency, simplicity, and good concealment, but the opposite is due to It cannot visually observe the construction status, and cannot obtain instant information on the construction interface, so there are the following inherent construction hidden dangers. The main manifestations are: first, insufficient grouting, resulting in insufficient foundation compactness, and second, excessive overpressure grouting, resulting in high-pre...

[0002] The development of the field of foundation engineering has led to a huge demand for foundation engineering construction. In the field of foundation engineering construction, ground grouting construction is often involved. High-pressure grouting construction is widely used because of its high efficiency, simplicity, and good concealment, but the opposite is due to It cannot visually observe the construction status, and cannot obtain instant information on the construction interface, so there are the following inherent construction hidden dangers. The main manifestations are: first, insufficient grouting, resulting in insufficient foundation compactness, and second, excessive overpressure grouting, resulting in high-pressure grout damage All kinds of pipelines in the construction area, at the same time, due to the excessive and overpressure grouting, the construction strata will be uplifted, the road will be damaged, and in severe cases, the ground buildings will be tilted and the structure will be damaged.
