Embedded device for electrochemically detecting or repairing reinforcing bars in concrete

Abstract

The invention discloses an embedded device for electrochemically detecting or repairing reinforcing bars in concrete. The embedded device comprises a joint, a positioner, a clamp and a conductive rod, wherein the joint comprises an outer sleeve and a conductive block; the outer sleeve is fixed on the positioner; the positioner is fixedly connected with the clamp; the conductive block is arranged in the outer sleeve and is electrically connected with the conductive rod and the clamp. The embedded device is simple in structure and convenient to install; after the device is installed, during the service of a structure, the conductive rod is inserted to enable the structure to be electrically communicated with the reinforcing bars; by virtue of electrochemical detection equipment, the reinforcing bars in the concrete can be electrochemically tested or dechlorinated and repaired by using various electrochemical testing methods, rich electrochemical parameters are obtained, and a corrosion state of the reinforcing bars is accurately mastered; the whole operation process is simple and quick, a concrete protection layer does not need to be broken in advance, the later-stage detection cost of the structure is saved, and the durability of the reinforcing bars is not influenced.

Description

technical field [0001] The invention belongs to the technical field of durability detection of concrete structures in civil engineering, and in particular relates to a pre-embedded device for electrochemical detection or repair of steel bars in concrete. The device is mainly used for electrochemical detection or repair of steel bars in concrete. Background technique [0002] The durability of concrete structure refers to the concrete structure and its components, under the influence of the foreseeable working environment and internal factors of the material, to resist atmospheric influence, chemical erosion and other deterioration processes within the expected service life without spending a lot of money on maintenance , can also maintain its security and applicability functions. However, with the passage of time and the sharp deterioration of the environment, reinforced concrete structures have exposed more and more serious durability problems, especially the corrosion of s...

AI Technical Summary

Problems solved by technology

The disadvantages of this technical solution are: ①The damage to the concrete is very large. Although the damaged part will be repaired later, the bond strength of the interface between the new and old concrete will be significantly reduced, which is not conducive to the structural stress

② The permeability of the interface between new and old concrete will increase significantly, which will promote the erosion of external corrosive media and greatly affect the durability of concrete structures

③Using the existing technical solution, the later maintenance cost will be greatly increased, especially for the detection of some inconvenient construction parts, the use of the existing technical solution will greatly increase the difficulty of construction, and it is difficult to control the construction quality
