Problems solved by technology

[0003] The traditional grouting method determines the required grouting position in advance, then excavates the grouting hole inside the earthwork, and inserts the grouting pipe into the grouting hole for grouting, but this method has the following disadvantages: First, due to the It is relatively loose, and when the grouting pipe body extends into the grouting hole, the pipe body will inevitably collide with the grouting pipe wall, causing debris, soil clods and other sundries to fall off the pipe wall, and these sundries can easily damage the grouting pipe If the head is blocked, the subsequent grouting will not be smooth, which will affect the grouting efficiency; secondly, during grouting, due to the high pressure of grouting, the mud in the grouting pipe will gradually rise, resulting in an increase in the internal pressure of the grouting pipe. If the grouting pipe or the grouting device is not closed, the mud will gradually be sprayed out from the rotary pile, and a large amount of grouting fluid will be lost, which will not only pollute the environment, but also the grouting pressure will dissipate sharply, making the grouting The grout inside the pipeline cannot efficiently enter the gaps inside the earthwork, and the grouting pressure dissipates more seriously as it reaches the surface layer, resulting in the shallow or even deep parts failing to meet the reinforcement requirements and seriously affecting the grouting effect

Abstract

The invention relates to the technical field of grouting equipment, and discloses a grouting device for slag slope support and collapse prevention. . Through the arrangement of the pulling rope, the collar, the extrusion plate and the rubber ring, a bypass hole is opened on the side of the pipe body for grouting. At the same time, the pull rope will also drive the collar to move down, so that the baffle will block the return channel to ensure that the grouting pressure inside the pipe body is sufficient, and it will also drive the first support rod to squeeze the extrusion plate to the outside. The rubber ring expands laterally and the grouting pipeline is blocked, which not only avoids the gradual ejection of mud from the grouting pipeline, the loss of a large amount of grouting liquid, the excessive amount of slurry, and the pollution of the environment. The grouting pressure inside the grouting pipeline dissipates rapidly to ensure the grouting effect.

Description

technical field [0001] The invention relates to the technical field of grouting equipment, in particular to a grouting device used for slag slope support and collapse prevention. Background technique [0002] The muck slope is an inclined free surface formed by manual filling in earthwork engineering. Since the filling is rolled and stacked step by step during the formation process, the physical and mechanical properties of the filling are poor, so the filling formed by accumulation The slope is not stable, and accidents such as landslides are prone to occur. Therefore, it is necessary to take reinforcement and prevention measures to control the fill slope. Usually, the slurry is filled inside the earthwork to solidify the slurry inside the earthwork, which can play a better role in the earthwork. Good reinforcement is a commonly used prevention and reinforcement measure in slope management. [0003] The traditional grouting method determines the required grouting position ...
