Concrete dam joint leaking stoppage method
The invention relates to a concrete dam joint leaking stoppage method. According to the method, a leaking stoppage device is used, when leaking is stopped, a leaking stoppage liquid storage container is placed at the highest position of a dam crest or a leaking joint, a leaking stoppage liquid collection pool is placed at the lowest position of the leaking joint, a liquid outlet of a drain pipe is formed at the highest position of the leaking joint, leaking stoppage liquid is filled in the leaking stoppage liquid storage container and aerated by turning on an aerator, a drain valve is opened after 5-30 minutes, the leaking stoppage liquid flows in from the highest point of the leaking joint, the size of the valve is adjusted, so that the flow of the leaking stoppage liquid is slightly lower than that of the leaking joint, a recovery pump is turned on after the leaking stoppage liquid flows out from the leaking stoppage liquid collection pool, and the cycle continues until the joint is plugged. Microorganism leaking stoppage liquid is mineralized to stop leaking, is fine in flowability and easily penetrates into a dam, the flow path of the leaking stoppage liquid is a leaking passage, and fine leaking joints and leaking joints with thin upstream and thick downstream can be stopped from leaking.
