Anchor rod corrosion prevention method

Abstract

The invention relates to the field of construction engineering, in particular to an anchor rod corrosion prevention method. The method comprises the steps that the parts inside a base and outside the base of an anchor rod are both subjected to corrosion prevention processing; according to the steps for corrosion prevention processing of the part inside the base of the anchor rod, flexible corrosion prevention surface treatment is conducted, a flexible corrosion prevention coating is covered with a waterproof material, and a rubber layer is wound and fixed outside the waterproof material; according to the steps for corrosion prevention processing of the part outside the base of the anchor rod, flexible corrosion prevention surface treatment is conducted, and the anchor rod is sleeved with a protection cap. According to the anchor rod corrosion prevention method, the two parts inside and outside the base of the anchor rod are subjected to different corrosion prevention processing, the outer part exposed out of the base and the inner part extending into the base are subjected to different corrosion prevention processing, particularly, the part inside the base is subjected to flexible corrosion prevention, the phenomenon that a corrosion prevention layer on the surface of the anchor rod is damaged when the anchor rod is deformed due to stress is avoided, the corrosion prevention capacity is improved, and the service life of the anchor rod is prolonged.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to an anticorrosion method for anchor rods. Background technique [0002] Anchor is a rod system structure for rock and soil reinforcement. Through the longitudinal tension of the bolt body, the shortcoming that the tensile capacity of rock and soil is far lower than the compressive capacity is overcome. [0003] On the surface, it restricts the separation of rock and soil from the original body; from a macroscopic point of view, it increases the cohesion of rock and soil. From a mechanical point of view, it mainly improves the cohesion C and internal friction angle of the surrounding rock mass. . In essence, the anchor rod is located in the rock and soil body and forms a new complex with the rock and soil body. The anchor rod in this complex is the key to solving the low tensile capacity of the surrounding rock mass, so that the bearing capacity of the rock and soil mass...

Problems solved by technology

[0007] The conventional method of anti-corrosion for anchor rods is to use other rigid anti-corrosion methods such as galvanizing, electrophoresis, etc., but for anchor rods used for post-tensioning to apply prestress, elongation will occur due to prestressing, and cracks will occur on the rigid anti-corrosion surface After a long time of operation, the anchor will be corroded here, which will seriously endanger the normal use of the anchor.
