SEWERAGE TUNNEL AND CONSTRUCTION METHOD FOR THE SAME
To form a water stream even with a small amount of sewage in an upper space or a lower space.SOLUTION: A sewerage tunnel 1 comprises an egg-shaped segment ring 1a, and an inner lid partition part 10 partitioning the egg-shaped segment ring 1a into two stages of an upper space 12 and a lower space 13. The inner lid partition part 10 is formed into a roughly concave face convexed to the lower space 13 side. A large diameter circular arc part 3 formed of a large diameter segment 2 and the inner lid partition part 10 form the roughly circular upper space 12. A roughly circular arc shape of the inner lid partition part 10 can collect even a small amount of rainwater at the bottom thereof and accelerate the flow speed. The inner lid partition part 10, a small diameter circular arc part 5 and a connected circular arc part 7 connecting both ends of the large diameter circular arc part 3 and the small diameter circular arc part 5 form the lower space 13. The diameter of the small diameter circular arc part 5 is smaller than that of the inner lid partition part 10, therefore, a water stream can be formed with a small amount of water.SELECTED DRAWING: Figure 1
【課題】上部空間や下部空間の排水等の水量が少なくても水流を形成できる。【解決手段】下水道トンネル１は、卵型セグメントリング１ａと、卵型セグメントリング１ａを上部空間１２と下部空間１３の二段に仕切る中蓋仕切部１０と、を備えた。中蓋仕切部１０は下部空間１３側に凸をなす略凹曲面状に形成されている。大径セグメント２からなる大径円弧部３と中蓋仕切部１０で略円形の上部空間１２を形成する。中蓋仕切部１０は略円弧状に形成されているため、雨水等の水量が少なくてもその底部に水を集めて流速を高めることができる。中蓋仕切部１０と、小径円弧部５と、大径円弧部３及び小径円弧部５の両端部を連結する連結円弧部７で下部空間１３を形成する。小径円弧部５は中蓋仕切部１０より小径であるため、水量が少なくても水流を形成できる。【選択図】図１
