Foundation pit inclined strut structure
By setting up a combined structure of foundation pit retaining piles, reinforced soil piers, and inclined piles in the foundation pit, and using high-pressure jet grouting technology to form hardened soil piers of different strengths, combined with enlarged head and prestressing technology, the problems of pile end settlement and construction complexity of the inclined pile support system were solved, and the stability and economy were improved.

Abstract
This invention proposes a foundation pit inclined bracing structure, including foundation pit retaining piles, inclined piles, reinforced soil piers, and a displacement compensation device. The foundation pit retaining piles are installed along one side of the foundation pit wall, and the reinforced soil piers are filled below the bottom of the foundation pit, with the retaining piles located at the edge of the pit. One end of the inclined pile is connected to the capping beam at the end of the retaining pile via the displacement compensation device, and the other end of the inclined pile is pre-embedded in the reinforced soil pier. This invention provides effective support for the pile end by designing a hardened soil pier, preventing pile end settlement. Furthermore, by setting an enlarged head at the pile end, the contact area between the pile end and the hardened soil pier is further increased, further improving the bearing capacity of the pile end. Compared with traditional inclined bracing structures, the construction of this invention is simpler and more efficient.
