RUGGED SLOPE FILLING AND WATER CUTOFF SYSTEM FOR WASTE FILLED-UP LAND BY URETHANE FOAM

摘要

PURPOSE: The rugged slope filling and water cutoff system for a waste filled-up land by a urethane foam is provided to stabilize and level the rugged slope by a lightweight urethane foam with a good adhesive strength. CONSTITUTION: The process of installing a rugged slope filling and water cutoff system for a waste filled-up land by urethane foam is composed of: spreading urethane foam to form a urethane layer(30) at five centimeters high; building a drainage way made of synthetic resin to drain underground water; spreading a bentonite mat(63) on the urethane layer to cut off water leaking; spreading a geomembrane(65) on the bentonite mat; forming a geocomposite or geotextile layer(67) so called protective layer on the geomembrane to prevent the geomembrane from being damaged; forming a disused tire layer on the protective layer.
