Abstract
PURPOSE: To control the height of a rubber weir within a short time in the drought season by supplying water into the rubber weir with a pump by pumping up water from a reservior provided on a river bed or in a revetment at an upstream position with respect to the rubber weir.
CONSTITUTION: The reservoir 2 is constructed by digging the revetment or the river bed at an upstream position with respect to the rubber weir 1 installed on the river bed across the river and capable of being increased and decreased in height by supplying and discharging a liquid. The water contained in the reservoir 2 is pumped up with a pumping apparatus 8 and supplied into a pipe 10 communicating with the interior of the rubber weir 1. The internal pressure of the rubber weir 1 is regulated to increase or to decrease the height of the rubber weir 1 by setting the head H of the pipe 10 at an optional level.
