Figure 1 is a cross-sectional view of an automatic weir installed on a river, where is the main body of the automatic weir, is the riverbed surface and the automatic weir foundation, is the flowing water that overflows from the weir raising weir, and is the gap between the flowing water and the weir body. It represents the vacuum space created by
is the blade type (flowing water blocking piece) to provide ventilation to the present invention, and h1 is the height of the water level to be raised by the weir.
h2 is the design overflow height of the automatic weir, and h1+h2=H is the planned height of the weir. The figure below shows the condition where the weir body has fallen and the dotted line appears, and the water flows down along the planned riverbed with the same slope cross section as upstream and downstream where no weir has been installed. FIG. 2 is a plan view of FIG. 1, and FIG. 3 is a front view of a blade type (water blocking piece) attached to the top of the weir.

動・地鳴り・うなり等の発生防止をするために堰
体頂に刃型を取付けて通気性をもたせるの真空
々間発生による駆音防止装置。 In order to prevent the occurrence of vibrations, ground rumbling, rumbling, etc. due to resonance between the automatic weir overflow coating and the water pressure upstream of the weir, a blade type is attached to the top of the weir body to provide air permeability.This is a noise prevention device that generates noise between vacuum spaces.
