Embankment dam leaking stoppage method
The invention relates to an embankment dam leaking stoppage method. A cofferdam is built in the upstream of an embankment dam, all of the water in the cofferdam is discharged, a leaking stoppage liquid storage pool is formed between the cofferdam and the upstream of the embankment dam, a leaking stoppage liquid recycling pool is arranged in the downstream of the embankment dam and connected to the leaking stoppage liquid storage pool through a recycling pipe, and at least one recycling pump is mounted on the recycling pipe. The leaking stoppage operations include that leaking stoppage liquid is filled into the leaking stoppage storage pool and converges with the leaking stoppage liquid recycling pool after flowing through the embankment dam, the recycling pump is started when the leaking stoppage fluid seeps out of the other side of leaking joints and flows into the leaking stoppage liquid recycling pool, the leaking stoppage liquid is sent back into the leaking stoppage liquid storage pool, and the process is repeated until the seepage discharge of the embankment dam meets the requirements. According to the embankment dam leaking stoppage method, the leaking stoppage liquid is microbial leaking stoppage liquid which is good in flowability and capable of penetrating into the dam to reduce the overall permeability of the dam to the maximum of 1 %o of that before the treatment, and the flowing path of the leaking stoppage liquid is the leaking channel, so that the leaking channel is blocked in a targeted mode.
