CONSTRUCTION METHOD FOR STRUCTURE, AND PROTECTION METHOD FOR BEDROCK

摘要

PROBLEM TO BE SOLVED: To suppress deterioration in bedrock without coating a bedrock surface with spray mortar and the like. ! SOLUTION: A construction method for a structure such as a dam body includes: a step (S2) of coating an externally-exposed first excavated surface 1 (bedrock surface) with a chemical agent containing alkali metal silicate and alkali metal siliconate; a step (S4) of forming a second excavated surface 2 by excavating the first excavated surface 1, which is coated with the chemical agent, by a predetermined thickness t1; and a step (S6) of constructing the structure on the second excavated surface 2. !
