Abstract

PURPOSE: To save manual work in charging of water by arranging an adjusting pipe communicated with a siphon pipe so as to open its tip end on the upstream side of an undulation weir and intermitting the siphon action by the changes in the water level across the opening portion.
CONSTITUTION: A flexible film covering (baglike member) 1 is fixed to the river bed. The baglike member 1 is communicated with a pump 6 and a siphon pipe 7 through a water charge/discharge pipe 4. The opening end 11 of an adjusting pipe 10 communicated with the top portion of the siphon pipe 7 is opened on the upstream side of the member 1. With water charged by the function of the pump 6 when the water level on the upstream side is lower than the position of the opening end 11, air flows in from the opening end 11 to prevent the siphon action, so that the baglike member 1 expands. With water charged by the function of the pump 6 when the water level on the upstream side is higher than the position of the opening end 11, the siphon action discharges the water in the baglike member 1, so that the member 1 contracts.
