Description

Technical Field

[0001] The utility model relates to the technical field of grouting for reinforcing a deep vertical shaft stratum under a shaft, in particular to grouting equipment for reinforcing a deep vertical shaft stratum under a shaft. Background Art

[0002] Before the well is dug, a hole is drilled from the ground to the aquifer, and slurry is injected into the aquifer using grouting facilities installed on the ground.

[0003] The ground pre-grouting method is to drill a hole from the ground to the aquifer before the wellbore is dug, and use the grouting facilities set up on the ground to inject slurry into the aquifer. The slurry penetrates, diffuses, solidifies and fills the cracks and pores in the rock and soil, forming a curtain with a certain strength and basically impermeable around the wellbore.

[0004] At present, the deep vertical shaft stratum reinforcement grouting equipment in the prior art is usually inserted into a preset hole to grout the stratum. During grouting, due to the deep vertical shaft and the long grouting device, construction workers are required to pull the grouting upwards during grouting. The grouting device is heavy, and it is not easy for construction workers to work for a long time. There is a problem that the grouting device cannot be easily made to gradually rise. Moreover, during grouting, after the grouting is completed, some slurry remains in the grouting device, which can easily cause blockage of the grouting device, making it impossible to disassemble and clear it, making it inconvenient to use it again. There is a problem that the grouting device cannot be easily disassembled and cleaned. Utility Model Content
