Rainwater permeation weir

Abstract

Abstract PURPOSE:To obtain a small-sized rainwater weir by dividing the inside into the upper and lower parts by a filter and arranging a vertical pipe having a bag-shaped filter and allowing the inflow water to drain (permeate) through the filter. CONSTITUTION:Dividing into the first and second storage chambers A and B is performed by installing a flat plate-shaped filter 7 inside a rainwater weir body 1. A vertical pipe 4 connected with a rainwater pipe 30 is arranged, penetrating through the flat plate-shaped filter 7. and a bag-shaped filter 6 is suspended inside. An number of small holes 30 are drilled on the bottom plate 13 of the rainwater weir 1, and a filter 9 is arranged, and a permeation hole 14 is drilled on the side plate of the second storage chamber B, and surrounded by a filter 8. Further, a drain pipe 5 is connected at a rainwater effluence port in the upper part, and the bypass in the case when the water level rises is permitted. Therefore, a small-sized rainwater permeation weir 1 free from the clogging with fallen leaves can be obtained.
