Prestressed anchor cable and pile-socketed pile deep foundation pit supporting structure

Abstract

The application belongs to the technical field of deep foundation pit support, in particular to a prestressed anchor cable and interlocking pile deep foundation pit support structure, which comprises a protection base, a support plate is arranged above the protection base, rotating seats are fixedly connected to the bottom of both sides of the support plate, two vertical blocks are fixedly connected to one side of the top of the protection base, and a support protection mechanism is arranged in the inner cavity of the protection base; the support protection mechanism comprises a plurality of fixing seats, a plurality of threaded rods are arranged in the inner cavity of the protection base, a moving seat is arranged on the outer circle of the threaded rods through a threaded sleeve, and a plurality of connecting rods are arranged above the protection base; the above structure cooperates to enable the support plate to uniformly and comprehensively adhere to the support surface, avoid local stress concentration, improve the stress uniformity and structural integrity in the supporting process, ensure the efficient transmission of force, and enable the supporting force to be synchronously applied from multiple points and uniformly distributed on the support plate through the overall structural design.
