Abstract

The invention relates to an underground concrete crack electro-deposition repairing device. The underground concrete crack electro-deposition repairing device comprises an electrolytic deposition tank, a treatment box, a power pump and a cathode, wherein the electrolytic deposition tank is mounted at a concrete crack, used for storing an electrolyte solution in the electro-deposition repairing process and internally provided with an anode connected with a positive pole of a power supply; the treatment box is connected with a water inlet and a water outlet of the electrolytic deposition tank and used for adjusting the electrolyte solution discharged from the electrolytic deposition tank, and the adjusted electrolyte solution goes into the electrolytic deposition tank again; the power pump is used for realizing circulation of the electrolyte solution between the electrolytic deposition tank and the treatment box; and the cathode is a steel bar arranged in the concrete crack and is connected with the negative pole of the power supply. Compared with the prior art, the underground concrete crack electro-deposition repairing device has the advantages that concrete acidification is effectively prevented by circulating the electrolyte solution; the concentration and pH of the electrolyte solution are maintained for a long term without affecting the concrete performance, and meanwhile,deposition repairing is promoted to be continuously and effectively carried out; and the underground concrete crack electro-deposition repairing device can be used for repairing underground structuralcracks at different heights through the power pump.

Description

technical field [0001] The invention relates to the field of repairing underground concrete cracks, in particular to an electrodeposition repairing device and method for underground concrete cracks. Background technique [0002] Concrete is prone to cracks due to its shortcomings such as high brittleness and low tensile strength. Cracks not only affect the safety performance and durability of concrete structures, but also provide convenient channels for the intrusion of harmful ions, further accelerating the performance degradation of concrete structures. Compared with the above-ground structure, the underground structure is more prone to cracks under the joint action of load and rock-soil medium, and under the action of groundwater, cracks have a greater impact on the long-term durability of the underground structure. Therefore, it is of great significance to carry out the repair of cracks in underground structures. [0003] Traditional methods for repairing concrete crac...
