Problems solved by technology

[0002] Bored cast-in-situ piles are widely used in foundation pit enclosure and slope support projects. The pile-shaped cross-sections of bored piles in the prior art are all circular, and the steel cages involved are mostly circular, that is, circular bored piles. Hole cast-in-place pile, this type of circular bored cast-in-place pile can be used as a vertical bearing member to achieve the purpose of uniform stress, but as a support pile for foundation pit enclosure and slope support projects that mainly resist horizontal forces , most of the steel bars in the circular steel cage are difficult to effectively play its role, which greatly wastes the material. In addition, the existing bored piles have poor durability and are difficult to adapt to different geology conditions. In view of the above problems, Those skilled in the art urgently need to provide a kind of new technical solution to solve the above problems

Abstract

The invention belongs to the field of foundation pit supporting and slope retaining, and particularly discloses a steel bar cage for a cast-in-situ bored pile. The cross section of the steel bar cage is a polygon. The steel bar cage comprises resistance facing steel bars, supporting steel bars and constructional steel bars. The constructional steel bars are wound into polygons, a plurality of lantern rings are arranged on the sides of the polygons formed by winding the constructional steel bars, and the resistance facing steel bars capable of moving relative to the lantern rings are arranged in half of the lantern rings.

Description

technical field [0001] The invention relates to the field of foundation pit enclosure and slope support, in particular to a reinforcement cage for bored piles. Background technique [0002] A large number of bored piles are used in foundation pit enclosure and slope support engineering. The pile-shaped cross-sections of the bored piles in the prior art are all circular, and the steel cages involved are also mostly circular, that is, circular drilled piles. Bored piles, this type of circular bored piles can be used as vertical bearing members to achieve the purpose of uniform stress, but as support piles for foundation pit enclosure and slope support projects that mainly resist horizontal forces , most of the steel bars in the circular steel cage are difficult to effectively play its role, which greatly wastes the material. In addition, the existing bored piles have poor durability and are difficult to adapt to different geology conditions. In view of the above problems, Tho...
