Self-adsorption emergency plugging structure for water leakage channel

The utility model discloses a self-adsorption emergency plugging structure for a water leakage channel, which is characterized in that a flexible adhesive film is laid on the upstream face of the water leakage channel, and the flexible adhesive film is adsorbed to the upstream face of the water leakage channel by utilizing the water pressure difference generated by leakage, so that the effect of plugging the water leakage channel is achieved; the flexible adhesive film is good in flexibility, serves as a sealing structure, is sensitive to water pressure difference, can be automatically adsorbed on a rigid or rock-soil structure under the action of the internal and external water pressure difference, is good in watertight effect, has excellent attaching and wrapping effects, and can be self-adaptive to the problems of irregularity of a water leakage channel and unconformity of a contact surface; and good adsorption capacity can be generated at a water leakage position, so that a small leakage channel is blocke
