Abstract

The invention relates to the technical field of drilling machine grouting, and particularly discloses a grouting control method. The grouting control method comprises the following steps of acquiringcement slurry pressure data of a current stratum in real time; comparing the cement grout pressure data of the current stratum with a preset cement grout pressure value to obtain a comparison result;and generating a control signal according to the comparison result, wherein the control signal is used for controlling an execution mechanism to execute cement slurry injection, redundant cement slurry suction or cement slurry injection stopping. The invention further discloses a grouting control device and system. According to the grouting control method, smooth grouting can be ensured, intelligent control is realized, and the problem of insufficient grouting or excessive overpressure grouting in the prior art is avoided.

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...
