METHOD OF INSTALLING ROLL-LIKE WATER STOP TO UPPER PART OF CONCRETE PLACING SCHEDULED PART IN CONCRETE DAM CONSTRUCTION, AND ROLL-LIKE WATER STOP SUPPORT MEMBER USED IN THE METHOD
PROBLEM TO BE SOLVED: To easily perform installation work of a roll-like water stop to an upper part of a concrete placing scheduled part without assembling a derrick.;SOLUTION: When constructing a concrete dam, the method is for installing a roll-like water stop for which a belt-like water stop is wound in a roll shape to the upper part of the concrete placing scheduled part when installing a mold form movable upwards at a position to be a wall surface of the concrete dam and installing a water stop along a mold form surface of the mold form so as to be over blocks adjacent to each other. By attaching a roll-like water stop support member for supporting the roll-like water stop by inserting a shaft to the center of the roll of the roll-like water stop and supporting the shaft at the upper part of the mold form movable upwards, the roll-like water stop is installed at the upper part of the concrete placing scheduled part.;COPYRIGHT: (C)2013,JPO&INPIT
