s3, gasifying the aqueous solution (13) through the gasification rod (14) at high temperature to generate condensation on the surface of the gasification rod (14), wherein the condensation is contacted with the ammonium nitrate net (12) to absorb heat and freeze the condensation;
s4, when groundwater permeates into the anti-collision pipe (1), the groundwater in the anti-collision pipe (1) is absorbed through the water guide fibers (17), guided to the water absorption resin (16) through the water guide cotton (18), and absorbed through the water absorption resin (16).
