| 摘要 | PURPOSE:To make easier the construction of underwater concrete structure by a method in which formworks are assembled using metal nets as sheathing boards, and underwater concrete is placed into the formworks to bury the metal nets. CONSTITUTION:Wheel-in-anchors are buried in an existing revetment B, spacers 2 are projected horizontally, and metal nets 1 are erectly set at a fixed interval from the revetment B. Vertical batters 3 are erected along the metal nets 1 on the opposite side of the revetment B, the ends of spacers 2 are pierced through the long holes of the batters 3, and cross batters 4 are held by holders 5 to assemble a formwork C. Underwater concrete is placed between the metal net 1 and the revetment B to bury the metal net 1, and after the concrete hardens, the vertical and cross batters 3 and 4 are removed out to obtain an underwater concrete structure A. | ||||||
