REPAIR CONSTRUCT OF UNDERWATER WALL SURFACE OF STRUCTURE AND REPAIR METHOD FOR THE SAME
PROBLEM TO BE SOLVED: To provide a repair construct of an underwater wall surface of a concrete structure, the repair construct capable of shortening a repair construction period, eliminating passage disorders such as ships, shortening an underwater work time of a worker, and superior in safety, and provide a repair method for the same.SOLUTION: A concrete form support board 2 disposed in a bottom ground 51 comprises a substrate 3 and a support plate 4 standing up substantially at a right angle. A form 6 is installed with a lower end supported by the form support board 2 while facing an underwater wall surface 52A containing a repair wall surface 52B of a concrete structure 52, and an upper end side supported by the upper end side of the structure 52. A form supporting cord 8 fixes a base end side to the underwater wall surface 52A, the tip side of a cord 8A is inserted to the form 6 and engaged by a clip 8D, and thereby the form 6 is supported at intervals of approximately 500 mm with respect to the underwater wall surface 52A. Underwater insoluble mortar is filled and solidified in a space 7 between the form 6 and the underwater wall surface 52A to cover the underwater wall surface 52A by a concrete layer 10, and the form 6 is disengaged and removed from the form supporting cord 8.SELECTED DRAWING: Figure 1
【課題】補修工期を短縮でき、船舶等の通行障害も無く、作業員の水中作業時間が短い安全性に優れたコンクリート製構造物の水中壁面の補修用構成体及びその補修工法を提供する。【解決手段】水底地盤５１に配置するコンクリート製の型枠支持盤２は、基板３と略直角に起立する支持板４とから成る。コンクリート製構造物５２の補修壁面５２Ｂを含む水中壁面５２Ａに対向して型枠支持盤２に下端を支承させ、上端側は構造物５２の上端側に支持させて型枠６を設置する。型枠支持索８は水中壁面５２Ａに基端側を固着し、型枠６にコード８Ａの先端側を挿通してクリップ８Ｄにより係着し、型枠６を水中壁面５２Ａに対して約５００ｍｍの間隔に支持する。型枠６と水中壁面５２Ａとの空間７に水中不分離性モルタルを充填固化して水中壁面５２Ａをコンクリート層１０で覆い、型枠６は型枠支持索８から離脱させて撤去する。【選択図】図１
