Vertical-to-transverse bidirectional constraint anchoring pile supporting structure and construction method thereof

Abstract

The invention discloses a vertical-to-transverse bidirectional constraint anchoring pile supporting structure. The structure comprises a plurality of anti-slide piles which are arranged in parallel and vertically or obliquely, top beams and brackets are arranged at the tops of the anti-slide piles; an inter-pile baffle is arranged between every two adjacent anti-slide piles; a first anchor cable is arranged at the top of the bracket; one end of the first anchor cable is connected with the top of the bracket through a first anchor head, an anchor cable steering device is arranged on the bracket, one end of the anchor cable steering device is fixedly connected with one end of the first anchor cable, the other end of the anchor cable steering device is fixedly connected with one end of the second anchor cable, and the other end of the second anchor cable is fixed to the front side of the anti-slide pile through a second anchor head. Vertical constraint and transverse constraint are simultaneously provided through an anchor cable of the anchor cable steering device; the supporting function of the anchoring piles is achieved, the supporting points of the first anchor cables and the steering devices act on bracket vertical loads, the anti-slide pile top anti-overturning bending moment is provided, pile top deformation can be strictly controlled, the supporting cost is reduced, the reliability of a supporting structure system is improved, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of foundation pit and side slope support, in particular to a vertically rotating and horizontally bidirectional restraint anchor pile supporting structure and a construction method thereof. Background technique [0002] The anchor cables of the traditional anchor-stayed pile-slab retaining wall occupy a large horizontal space, causing most of the anchor cables to go out of the red line of the project site. Safety of supported structures. At present, some local governments have expressly stipulated that anchor cables and anchor rods are prohibited from exceeding the red line of the land. This paper proposes a support structure of vertically-rotating and horizontally restrained anchor piles, which realizes the supporting function of anchor piles and avoids the risk of uncontrollable anchor cables in the later stage when they go out of the red line. The vertical load of the legs provides the anti-overturning ...

AI Technical Summary

Problems solved by technology

[0002] The horizontal space occupied by the anchor cables of the traditional anchor-stayed pile slab retaining wall is relatively large, and it has become a common phenomenon that most of the anchor cables go out of the red line of the project land. There is a risk that the existing anchor cables may be damaged during the later development and construction of the connected land, which affects Safety of Supported Structures
