AI Technical Summary

Technical Problem

In traditional grouting processes, the transportation of bagged cement leads to dust pollution and resource waste, grouting equipment needs to be moved frequently, resulting in low efficiency and high labor intensity for multiple people working together.

Method used

The system employs a surface grouting mechanism and an underground grouting mechanism, including a cement silo, a screw feeder, a grout mixing machine, a grout storage mixing machine, a grout delivery pipeline, and a grouting pump. A three-way valve enables centralized preparation and rapid switching of the grout, reducing equipment relocation and manpower input.

Benefits of technology

It improved the efficiency of grouting operations, reduced dust pollution and resource waste, lowered labor intensity, freed up underground roadway space, and simplified the operation process.

Abstract

The application provides a ground-to-downhole grouting device, and relates to the technical field of coal mine grouting, which comprises a ground slurry supply mechanism and a downhole grouting mechanism. The downhole grouting mechanism comprises a slurry conveying pipeline arranged at multiple grouting sites, a grouting pump arranged on the slurry conveying pipeline, and a grouting machine connected with the slurry conveying pipeline. The grouting machine is provided with a grouting pipeline. A three-way valve is arranged on the grouting pipeline. The three-way valve is connected with two grouting branch pipes. The grouting branch pipes are used for grouting operation on multiple grouting holes at the grouting site. The ground slurry supply mechanism is used for conveying slurry to the slurry conveying pipeline. The device can reduce equipment relocation time, facilitate switching of different grouting sites, realize rapid switching of hole positions through the three-way valve, reduce downtime when switching grouting holes, and improve operation efficiency. The device centrally prepares slurry on the ground, releases the space of the downhole roadway, and avoids the occupation of the roadway transport capacity by the traditional bagged cement transportation.
