Abstract
PURPOSE:To easily perform temporary coffering work for dam by a method in which a number of ropes are stretched over the whole width of a dam at given intervals vertical and attached with vertical support beams, and a water- stop sheet is attached to the upstream side front face of the support beams. CONSTITUTION:In closing a water channel in the main gate 3A, winches 6 on both sides are operated and ropes 7 are vertically stretched over the whole width of dam 5. Support beams 8 are attached to the whole face of each rope 7 vertically at given intervals on the position between the piers 2 on both sides of the main gate 3A. A water-stop sheet 9 is set on the whole face of the beams 8 to interrupt the piers 2. The main gate 3A is raised to close it by the sheet 9.
