Method for reinforcing water retaining pavement

摘要

PROBLEM TO BE SOLVED: To provide a method for strengthening a water-retaining pavement capable of strengthening the water-retaining pavement without impairing the function of the water-retaining pavement. SOLUTION: A pavement step (S110) for paving an open-grained base pavement 10, a cement milk filling step (S120) for filling a void of the base pavement 10 with water-retaining cement milk 30, and the filled water-retaining material. A reinforcing layer forming step (S130) in which the breathable silicate 40 is sprayed on the surface of the cement milk 30 to form a reinforcing layer 31 on the surface layer of the water-retaining cement milk 30, and after the water-retaining cement milk 30 is cured. It is characterized by having a surface treatment step (S140) of shot blasting or grinding the surfaces of the base pavement 10 and the reinforcing layer 31. [Selection diagram] Fig. 4
