Anti-rust structure of foundation pile

Abstract

The invention relates to an anti-rust structure of a foundation pile. The anti-rust structure comprises a shaft vertically arranged below the ground, wherein a cylindrical reinforcement cage is arranged in the shaft, and the reinforcement cage is collinear with the axis of the shaft; an arc-shaped baffle is arranged in the shaft, and the diameter of a circle where the outer side of the arc-shapedbaffle is located is the same as the inner diameter of the shaft; a limiting assembly is arranged on the inner side of the arc-shaped baffle, the limiting assembly comprises a first sleeve hinged on the inner wall of the arc-shaped baffle, a lead screw is in threaded connection with the inside of the end, far away from the arc-shaped baffle, of the first sleeve, a second sleeve is in threaded connection with the outside of the end, far away from the first sleeve, of the lead screw, and the first sleeve and the second sleeve are close to or far away from each other when the lead screw rotates;and a hexagonal nut is fixedly connected to the middle position of the lead screw, a top plate is hinged to the end, far away from the first lead screw, of the second sleeve, and the arc-shaped baffleis made of plastic. The anti-rust structure disclosed by the invention has the beneficial effects of preventing the reinforcement cage in the foundation pile from rusting so as to ensure the strengthof the foundation pile and the service life.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an antirust structure of foundation piles. Background technique [0002] Karst landform is a general term for the surface and underground forms formed by the dissolution of soluble rocks (mostly limestone) by water with dissolution power. The main features are reflected in geographical phenomena such as karst caves and tiankengs. my country's karst landforms are widely distributed, such as Yunnan, Guizhou and other places. When carrying out construction in such areas, it is necessary to conduct surveys and avoid places where karst caves are more concentrated. Due to the complexity of the karst system, it is inevitable to encounter some hidden karst caves when excavating the wellbore of the foundation pile, which will cause certain difficulties to the construction. [0003] In the prior art, when the wellbore of excavating foundation piles encounters a karst cave, a...

Problems solved by technology

[0004] In the above scheme, after the concrete pouring is completed, the part of the iron plate that seals the karst cave will directly contact with air and water to cause electrochemical corrosion, so that the iron plate will be corroded in a large area. The cage will also be corroded, and the corrosion of the steel cage will seriously affect the strength and service life of the foundation pile
