STRUCTURE CONSTRUCTION METHOD AND BEDROCK PROTECTION METHOD
PROBLEM TO BE SOLVED: To reduce a workload to remove protective mortal or concrete on a surface of bedrock therefrom.SOLUTION: A construction method for a dam body, includes the processes to: apply a chemical agent to a first excavated surface 1 (bedrock surface) which is externally exposed (S2); place mortar 5 or concrete on the first excavated surface 1 with the chemical agent applied thereto (S3); remove the mortar 5 or the concrete from the first excavated surface 1 (S5); create a second excavated surface 2 by excavating the first excavated surface 1, with the mortar 5 or the concrete removed, by a predetermined thickness t1 (S6); and construct the dam body on the second excavated surface 2 (S8). The chemical agent reduces adhesion of the mortar 5 or the concrete to the first excavated surface 1.SELECTED DRAWING: Figure 1
【課題】岩盤面の保護用として岩盤面を覆うモルタル又はコンクリートを岩盤面から除去するときの作業負荷を軽減する。【解決手段】ダム堤体等の構造物の構築方法として、外部に露出した第１の掘削面１（岩盤面）に薬剤を塗布する工程（Ｓ２）と、薬剤が塗布された第１の掘削面１上にモルタル５又はコンクリートを更に塗布する工程（Ｓ３）と、モルタル５又はコンクリートを第１の掘削面１から除去する工程（Ｓ５）と、モルタル５又はコンクリートが除去された第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（Ｓ６）と、第２の掘削面２上にダム堤体を構築する工程（Ｓ８）と、を含む。薬剤は、モルタル５又はコンクリートの第１の掘削面１への付着力を低減させる。【選択図】図１
