Description

Technical Field

[0001] The present application relates to the technical field of foundation pit support, and in particular to a water conservancy embankment foundation pit support structure based on Larsen steel sheet piles. Background Art

[0002] With the rapid advancement of my country's urbanization process, the development and utilization of underground space has attracted more and more attention, thus giving rise to the concept of "foundation pit engineering". Foundation pit engineering mainly includes the design and construction of foundation pit support system and earth excavation. It is a highly comprehensive system engineering, among which the most important is the design and construction of support system.

[0003] The existing foundation pits are not sufficiently sealed and impermeable during support. Since groundwater is easily generated during the excavation process of the foundation pit, and the groundwater cannot be intercepted and protected in a timely and effective manner, the water will penetrate into the working area of ​​the staff in the foundation pit, which will cause the soil in the working area of ​​the foundation pit to be thin and water-poor, resulting in slow operation. In addition, the support mechanism of the existing foundation pit is not easy to assemble and disassemble, affecting the working efficiency. Utility Model Content
