Method for reinforcing water retaining pavement

摘要

Problem to be solved: to provide a waterproof pavement strengthening method capable of enhancing the water retaining pavement without damaging the function of the water retaining pavement.Solution: the pavement of the mother particle pavement 10 to be opened (S110) andThe cement milk filling process (S120) filling the gap of the mother pavement 10 with water retaining cement milk 30The porous silicic acid 40 was sprinkled on the surface of the said water retaining cement milkThe reinforcing layer forming process for forming the reinforcing layer 31 on the surface of the water retaining cement milk 30 (S130);After the water repellent cement milk 30 is hardened, the surface treatment step (SC140) is used for the shot blasting or grinding of the surface of the mother pavement 10 and the reinforcing layerIs characterized in thatDiagram
