Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sleeve valve grouting, in particular to a sleeve valve grouting device based on auxiliary directional anti-deviation. Background Art
[0002] A sleeve valve pipe is a pipe with multiple grouting holes. It mainly involves lowering the sleeve valve pipe through a drill hole to a predetermined depth in the formation, and then controlling the grouting process through a one-way valve (sleeve valve) on the sleeve valve pipe. During grouting, pressure is used to inject the grouting material into the sleeve valve pipe through the grouting pipe. Due to the special structure of the sleeve valve, the grouting material can only enter the formation from the grouting holes of the sleeve valve pipe and will not flow back. In this way, slurry can be injected into the formation in a segmented, fixed-point, and quantitative manner, so that the slurry diffuses and cements in the pores and cracks of the rock and soil under pressure, thereby achieving the purpose of strengthening the formation or stopping water. After the slurry solidifies in the cracks, it can effectively prevent the seepage of groundwater.
[0003] If the existing sleeve valve pipe is misaligned during grouting, the grouting position will deviate from the intended formation location, resulting in the slurry not being effectively injected into the formation area to be treated, greatly reducing the reinforcement effect. Moreover, the misalignment may cause the slurry to spread in non-target areas, failing to form the expected slurry shape and distribution range, reducing the effectiveness of the formation reinforcement or water stop. The misaligned sleeve valve pipe may cause the slurry to be injected into places where it should not be injected, which may cause deformation and rupture of underground pipelines, or uneven settlement and tilting of buildings, posing a serious threat to the safety of surrounding facilities.
