Abstract

The invention relates to the technical field of drilling engineering grouting, in particular to an extrusion device for drilling pressurized water slurry replacement and a construction process. The extrusion device comprises a pipeline and a device pipe, the inner side of the pipeline is spirally connected with the device pipe, the right end face of the device pipe is fixedly connected with a detection device, a sealing frame is arranged on the inner side of the upper portion of the device pipe, threads are arranged on the outer side of the sealing frame, the sealing frame is spirally connected with the device pipe through the threads, a rubber extrusion plug is arranged on the inner side of the sealing frame, a lifting device is fixedly connected to the upper end face of the rubber extrusion plug, and a discharging device is fixedly connected to the right side of the upper end face of the sealing frame. According to the device, through the arrangement of the discharging pipe, a valve,the rubber extrusion plug and the sealing frame, the rubber extrusion plug continuously extrudes forwards, and residual cement in a horizontal section hole is continuously extruded into a stratum until reaching a target hole section; by means of the arrangement, the device is convenient to use, can solve the hole sweeping problem caused by segmented grouting in existing drilling engineering, andgreatly improves the construction efficiency and construction cost.

Description

technical field [0001] The invention relates to the technical field of drilling engineering grouting, in particular to an extrusion device and a construction process for drilling water to replace grout. Background technique [0002] The current drilling engineering grouting technology is gradually being applied to the sealing and reinforcement of strata under various geological conditions, such as geological faults, goaf fissures, primary stratum fissures, etc., and grouting is carried out after drilling holes in the target area through directional drilling technology , while the grouting in the construction of the above-mentioned projects, the ground orifice is directly connected to the grouting pump for full-hole grouting. It is necessary to pull out all the drilling tools. Before grouting, it is necessary to press water to press the mud and mud cake in the hole into the formation. After the grouting is completed, it is necessary to press water again to press out all the c...
