Abstract

Expanded and variable-diameter reinforcement cage of pouch bag, including axial rod, ring or ring plate and several vertical ribs, several ribs, ring-shaped fixer, ring or ring plate is perpendicular to the axial rod, and one end of several vertical ribs is in the circle The ring or ring plate is evenly fixed, the other end or the middle of each vertical rib is connected to one end of a rib, several vertical ribs surround the axial rod, and the other end of the rib is connected to the ring-shaped fixer, the ring-shaped fixer Fix or slide on the axial rod or pile foundation rod; there is an outer bag to wrap the bottom of several vertical ribs, at least the bottom of the bag is closed, and the bag at the bottom of the pile wraps several vertical ribs; the bag is equipped with at least A grouting port and a grouting port with a one-way valve.

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...
