CONSTRUCTION METHOD FOR STRUCTURE, AND PROTECTION METHOD FOR BEDROCK
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.
【課題】岩盤面を吹付モルタル等で覆うことなく、岩盤の劣化を抑制する。【解決手段】ダム堤体等の構造物の構築方法として、アルカリ金属珪酸塩及びアルカリ金属シリコネートを含有する薬剤を、外部に露出した第１の掘削面１（岩盤面）に塗布する工程（Ｓ２）と、薬剤が塗布された第１の掘削面１を所定の厚さｔ１分掘削して第２の掘削面２を形成する工程（Ｓ４）と、第２の掘削面２上に構造物を構築する工程（Ｓ６）とを含む。【選択図】図１
