[0002] Groundwater is the natural enemy of deep foundation pit projects and one of the most direct causes of foundation pit project accidents. To address the problem of underground water and sand inrush, there are currently three commonly used technical means: water isolation, pressure reduction and bottom sealing.
[0003] Grouting is one of the commonly used water-isolating methods. Its principle is to prepare the cementing material into a slurry and inject it into loose sand-containing or water-containing strata, cracked rock strata, caves, and broken zones to solidify it. After the slurry solidifies and hardens, it plays a cementing and plugging role, making the strata stable and isolating water sources, reducing the permeability of rock and soil, increasing the strength and stability of the project, and achieving the purpose of rock and soil reinforcement and water blocking.
[0004] When grouting, it is necessary to drill a hole first so that the casing can penetrate deeper, and then complete the grouting through the grouting pipe. However, direct grouting after the casing is driven in has the problem of unclear soil conditions in the grouting area, resulting in unexpected consumption of slurry and waste of resources. For this reason, we propose a grouting reinforcement device for underground water and sand inrush. Utility Model Content
