Abstract

The invention discloses an intelligent-control multi-hole grouting machine and an operation method thereof. The intelligent-control multi-hole grouting machine comprises a grouting body, a grout incoming hole is formed in the grouting body and communicated with a grout incoming passage in the grouting body, the grouting incoming passage is divided into two branches through a diversion device, and a piston pump driven by a motor is mounted on each branch; outlets of the two piston pumps are jointly connected with one diversion unit which is connected with multiple grout outgoing holes through grout outgoing passages, a diversion valve is mounted on each grout outgoing passage, and an electromagnetic flowmeter and a hydraulic meter are connected at an outlet end of each diversion valve. The grouting machine is novel, efficient and stable, the problem that existing grouting machines are low in efficiency and unstable in pressure intensity in geotechnical engineering is solved, and construction efficiency and construction quality are improved substantially.

Description

technical field [0001] The invention relates to a novel intelligent control porous grouting machine for grouting and its operation method. Background technique [0002] As a reinforcement measure to effectively improve the bearing capacity and stability of surrounding rock, bolt grouting reinforcement technology has been confirmed by many engineering practices. The western part of my country is a mountainous area. The construction of high-speed railways and highways often requires reinforcement of the tunnel surrounding rock, high and steep slopes and side slopes along the line; at the same time, the construction of urban subways and high-rise buildings often requires excavation of tens of meters deep. The foundation pit also faces the enclosure of the pit wall. In the face of these projects, the traditional grouting machine takes a long time and has low efficiency, so that the efficiency and quality of the project cannot be effectively guaranteed.
