Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a retaining wall for an integrated submersible pump station. Background Technology

[0002] In water conservancy projects, retaining walls are a common and important structure. Their main function is usually to serve as a support structure to maintain the stability of slopes or excavation faces, protect banks and embankment toes from water erosion and washout, and provide reliable lateral support for adjacent hydraulic structures. With the continuous development of modern water conservancy, the function of retaining walls is no longer limited to "blocking soil" and has gradually evolved into a multifunctional, ecological, and intelligent composite structural system.

[0003] In existing pump station designs, retaining walls are often required on both sides of the inlet section of the station to support the backfill on both sides. The structure between the two types of buildings needs to be expanded with joints and waterstops. At the same time, since the required bearing capacity of the foundation of the pump station and the retaining wall often differs, if the foundation is soft soil, the foundation reinforcement treatment scheme and deformation coordination between the buildings also need to be considered. This increases the design difficulty and also creates hidden dangers for the later construction quality and safe operation. Utility Model Content
