Description

In order to ensure the safe and stable operation of reservoirs, it is very important to remove hazards and reinforce reservoirs. A crack repair device for reservoir removal and reinforcement has come into being. The device is designed to effectively deal with cracks in the reservoir structure, improve the overall safety and durability of the reservoir, and provide strong guarantees for the long-term reliable operation of the reservoir.

[0003] The patent application with application number CN202210551753.6 discloses a crack repair device for reservoir hazard removal and reinforcement, which mainly relates to the technical field of crack repair and cleaning equipment.
