Geotechnical engineering grouting process and geotechnical engineering grouting device

Abstract

The invention discloses a geotechnical engineering grouting process and a geotechnical engineering grouting device. The geotechnical engineering grouting device comprises a grout producing structure,a conveying structure and a drilling structure, wherein the grout producing structure comprises a movable plate, a stirring structure, a grouting pump and a guide structure; supporting columns are vertically welded to the top face of the movable plate; a stirring barrel is vertically fixed among the supporting columns; the stirring structure is horizontally arranged on the top faces of the supporting columns; the bottom end of the stirring barrel is connected with the grouting pump in a penetrating mode through a guide pipe; the guide structure is installed at the discharge end of the groutingpump; the conveying structure is installed on one side, away from the guide structure, of the movable plate; and the drilling structure is installed on the front part of the side end face of the movable plate. The geotechnical engineering grouting device can integrate a drilling machine, the grouting pump, a conveying pipe and a grout nozzle, thereby facilitating grouting, reducing the grouting process and procedures and improving the grouting efficiency and effect.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering grouting, in particular to a geotechnical engineering grouting process and device. Background technique [0002] With the acceleration of urbanization and industrialization in our country, and the increase in the density of infrastructure construction such as transportation and road networks, the available land resources are decreasing day by day, and many coal mine goafs are gradually listed as industrial and civil construction sites, resulting in some Buildings (structures) such as roads, railways, bridges, tunnel projects, and commercial houses in the region have to be built on the goaf or through the goaf. [0003] Most of the liquid injection machines used in the existing geotechnical engineering grouting include drilling machines, liquid injection pumps, transfer pipes and grout nozzles, but this combination requires the use of too many machines and transfer pipes to partici...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a geotechnical engineering grouting process and device, which aims to improve the existing liquid injection machinery, which mostly consists of drilling machines, liquid injection pumps, transmission pipes and grout nozzles. Many machines and transmission pipes are involved in the production and injection of grout, which has high cost, complicated grouting process, complicated process, and many turnover processes are inconvenient to use. Smaller, lower injection rate, poorer grouting effect
