TIMBERING WORK AND OVERFLOW PREVENTING WALL IN SUPERSTRUCTURE CONSTRUCTION OF CAISSON AND THE LIKE

摘要

PURPOSE:To permit dry-construction work as well as secure operating space by a method in which the first and second cut-off walls of a given structure are attached in combination according to the shape of the upper edge of caisson, etc., to form the timbering work for the superstructure by using the over-hanging parts of the walls. CONSTITUTION:A timbering work and overflow preventing wall 10 is made up of the first cut-off structures J, L, N, O, Q, R, and T which are divided into blocks according to the shape of the upper edge of caisson 1 and the second cut-off structures K, M, P, and S. The first cut-off structures have frames detachably attached by extending outwards to the upper edge of the caisson 1, having a height enough to prevent overflowing of waves. The second structures cover detachably the apertures of the first cut-off structures.
