Description

Technical Field

[0001] The utility model relates to the technical field of anti-seepage structures, in particular to a deep foundation pit support and dewatering anti-seepage structure. Background Art

[0002] With the expansion of urban underground space development, the rapid development of high-rise buildings, subways and high-speed railways, there are more and more deep foundation pit projects. In densely populated urban areas, in order to ensure the support structure during foundation pit construction and the safety of surrounding structures, real-time monitoring and analysis of deep foundation pit excavation and support is particularly important. Foundation pit dewatering refers to the process in which the groundwater level is higher than the bottom of the excavation when the foundation pit is excavated. Groundwater will continue to seep into the pit. In order to ensure that the foundation pit can be constructed under dry conditions and prevent slope instability, foundation sand flow, pit bottom uplift, pit bottom pipe burst and reduced foundation bearing capacity, dewatering and anti-seepage work is done. Most of the existing dewatering and anti-seepage structures adopt a one-way setting, which is of low practicality. In this process, groundwater will continue to seep into the pit, and may even cause accidents such as the collapse of the foundation pit and damage to surrounding buildings. Therefore, we propose a deep foundation pit support dewatering and anti-seepage structure to solve the above problems. Utility Model Content
