A hydraulic support system for construction of a super deep foundation pit

Abstract

The utility model discloses a hydraulic support system for superdeep foundation pit dismantling and replacing support construction, which is used to improve the adaptability and construction efficiency of a foundation pit support system. The hydraulic support system comprises a horizontal embedded steel column, a longitudinal embedded steel column and a vertical embedded steel column, which are embedded in a concrete retaining wall of a foundation pit, a raft foundation of the foundation pit and a foundation pit respectively. The horizontal embedded steel column, the longitudinal embedded steel column and the vertical embedded steel column are connected to a steel structure space node through corresponding standard steel columns respectively. The steel structure space node comprises a horizontal oil cylinder, a longitudinal oil cylinder and a vertical oil cylinder, which are connected to the standard steel columns respectively. The utility model has strong three-dimensional self-adaptive adjustment capability, greatly improves the adaptability to the deformation of a superdeep foundation pit, can realize real-time monitoring combined with active pressure control, significantly improves the construction safety, greatly improves the disassembly and assembly efficiency through a modularized splicing design, shortens the construction period of the superdeep foundation pit, and the components can be reused and are green and environmentally friendly, thereby reducing the construction cost. The structure has strong stability and can meet the high load demand of a superdeep foundation pit.
