Abstract

PURPOSE: To form a rubber-made beltlike hollow member excellent in airtightness and having desired length and thickness and to utilize the member as a weir of a rubber dam.
CONSTITUTION: A beltlike hollow member 1 is made of a rubber or the like reinforced with canvas 2 or the like, and comprises an expansion portion 1a which becomes tubular when filled with air, water, or the like, and a platelike portion 1b integrally provided on one side of the portion 1a. To compose a rubber dam of the member 1, the member 1 is reinforced by burying a bead wire or steel cord 8 in the portion 1b, and a holder metal 9 extending longitudinally is fastened by an anchor bolt 10 embedded in a river bed 7 and a net 11 in such a manner that the holder metal 9 presses the bead wire 8 in the portion 1b. Thus, a rubber dam of high durability can be constructed efficiently.
