Foundation pit, waterproof structure, and construction method thereof
The invention discloses a foundation pit, a waterproof structure and a construction method thereof. The construction method of the waterproof structure is applied to the foundation pit and includes the steps that first grouting pipes are lowered into a stratum corresponding to a to-be-excavated area of the foundation pit, waterproof grout is injected into the stratum through the multiple first grouting pipes, and a water-resisting layer is formed at a depth corresponding to the first grouting pipes; second grouting pipes are lowered into the stratum corresponding to the periphery of the to-be-excavated area; and the second grouting pipes are rotated according to a specified direction, and reinforcing grout is injected into the stratum through the second grouting pipes, so that the reinforcing grout is sprayed to the joint of a connecting wall to form a reinforcing body located at the joint. According to the technical scheme, a confined water layer is effectively separated, so that precipitation in the foundation pit becomes a closed system.
本发明公开一种基坑、隔水结构及其施工方法，其中，一种隔水结构的施工方法，应用于基坑，所述施工方法包括：将第一注浆管下放至所述基坑的待开挖区域对应的地层内，通过所述若干第一注浆管向地层内注入隔水浆液，以在与所述第一注浆管对应的深度处形成隔水层；将第二注浆管下放至所述待开挖区域的周围对应的地层内；按照指定方向旋转所述第二注浆管，并通过所述若干第二注浆管向地层内注入加固浆液，使得所述加固浆液喷射至连墙的接缝处而形成位于所述接缝处的加固体。本发明技术方案旨在有效地隔断承压水层使基坑内降水成为一个封闭的体系。
