Abstract

The invention discloses a bag expansion diameter-variable steel reinforcement cage. The bag expansion diameter-variable steel reinforcement cage comprises an axial rod, a circular ring or an annular plate, several longitudinal ribs, several rib strips and a ring-shaped fixator, the circular ring or the annular plate is perpendicular to the axial rod, one end of each longitudinal rib is uniformly fixed to the circular ring or the annular plate, the other end or the middle of each longitudinal rib is connected to one end of a corresponding rib strip, several longitudinal ribs surround the axialrod, the other end of each rib strip is connected to the ring-shaped fixator, and the ring-shaped fixator is fixed to or slides on the axial rod or a pile foundation rod; an outer bag covers the bottoms of the several longitudinal ribs, at least the bottom of the bag is sealed, and the bag with an expanded pile bottom end covers several longitudinal ribs; at least one slurry injecting opening anda slurry outlet with a one-way valve are formed in the bag.

Description

1. Technical field [0001] The present invention relates to a bag expansion variable diameter reinforcement cage and anchor rod or pile foundation, especially the skeleton in the anchor rod or pile foundation - bladder expansion variable diameter reinforcement cage and its expanded body anchor rod or pile foundation. It is used in technical fields such as anti-floating foundation pit support, slope support, and reinforcement of building basements. 2. Background technology [0002] The anchor rod must have several elements: a rod body whose tensile strength is higher than that of the rock and soil body, and one end of the rod body can be in close contact with the rock and soil body to form friction (or bond) resistance; the other end of the anchor rod body located outside the rock and soil body can Form the radial resistance to the rock and soil mass; as a tension member that goes deep into the strata, one end of the bolt is connected to the engineering structure, and the othe...
