Method for preventing piping inrush of coast geological deep foundation pit
The invention provides a method for preventing piping and inrush of a coast geology deep foundation pit, belongs to the technical field of water conservancy projects, and solves the problem that piping and inrush risks are caused by the fact that water can not be discharged quickly in a traditional precipitation method. The retaining structure of the foundation pit adopts a cast-in-situ bored pile and three-axis cement-soil mixing pile-shaped soil retaining and water stopping system, the retaining structure cuts off the hydraulic connection between underground water and peripheral underground water within the excavation depth range of the foundation pit, and the foundation pit adopts a supporting structure for supporting and stabilizing the wall of the foundation pit. The method for preventing piping and inrush of the coast geological deep foundation pit comprises the following steps that S1, data are collected; s2, data processing; and S3, making a precipitation scheme. The layered dewatering and layered excavation method is adopted, and the water level in the foundation pit is controlled by arranging the drainage well, so that it is ensured that the interior of the foundation pit is dry, and the piping problem is prevented. And the depressurization well is used for controlling the burial depth of the confined water head so as to prevent the outburst problem.
本发明提供了一种预防海岸地质深基坑发生管涌突涌的方法，属于水利工程技术领域，解决了传统降水方法可能无法快速将水排出，从而导致管涌和突涌风险。本发明基坑的围护结构采用钻孔灌注桩和三轴水泥土搅拌桩形挡土止水体系，所述围护结构隔断基坑开挖深度范围内地下水与外围地下水的水力联系，所述基坑采用支撑结构用于支持和稳定基坑壁，所述预防海岸地质深基坑发生管涌突涌的方法，包括以下步骤：S1、收集数据；S2、数据处理；S3、制定降水方案。本发明采用分层降水和分层开挖的方法，通过设置疏干井来控制基坑内部的水位，以确保基坑内部干燥，并防止管涌问题的发生。使用降压井来控制承压水头埋深，以预防突涌问题的出现。
