Description

A cementer that is used for dregs side slope to strut anti-collapse

Technical Field

The invention relates to the technical field of grouting equipment, in particular to a grouting device for preventing the collapse of a muck slope support.

Background

The muck side slope is an inclined free surface formed by artificial filling in the earthwork, and is formed by gradually rolling and piling the filling in the forming process, the physical and mechanical properties of the filling are poor, so that the piled filling side slope is unstable and easy to collapse, and other accidents happen, so that the filling side slope needs to be treated by adopting a reinforcement prevention and control measure, and slurry is usually filled into the earthwork to be solidified in the earthwork, so that the slurry can play a good role in reinforcing the earthwork, and the muck side slope is a commonly used prevention and control reinforcement measure in the side slope treatment.

Traditional grout mode is through confirming required grout position in advance, then at the inside grout hole of excavation of earthwork, through stretching into the grout hole with the grout pipe and grout, but this kind of mode exists following not enoughly: firstly, as the inside of the muck side slope is loose, the grouting pipe body inevitably collides with the wall of a grouting pipeline when extending into a grouting hole, so that sundries such as broken stones and soil blocks fall off from the pipe wall, and the sundries easily block the head of the grouting pipe, cause unsmooth subsequent grouting and influence the grouting efficiency; secondly, when grouting, because the pressure of slip casting is great, the mud in the slip casting pipeline can rise gradually, lead to slip casting pipeline internal pressure to be bigger and bigger, if slip casting pipeline or slip casting device do not have the closure measure, just lead to mud to spout outward from the swivel pile gradually, the slip casting liquid runs off in a large number, not only the polluted environment, but also slip casting pressure can be rapidly dissipated for the inside thick liquid of slip casting pipeline can't the high efficiency get into the inside gap of earthwork, and the surface layer is gone beyond, slip casting pressure dissipates more seriously, thereby cause shallow portion even deep portion can't reach the reinforcement requirement, seriously influence the slip casting effect.
