U-shaped concrete ditch bottom
The invention provides a U-shaped concrete ditch bottom. The cross sections of all ditch bottoms except pipelines are flat, so that sediments are difficult to wash. The U-shaped concrete ditch bottomis improved in a way that the ditch bottom is not flat, but the two sides of the ditch bottom are slope-shaped U-shaped or V-shaped, so that sandy soil, dirt and the like are difficult to deposit on the two slope-shaped sides of the ditch bottom, the dirt and sewage are concentrated in the center of a ditch, and the sewage and the dirt can be washed with small water and are easy to wash cleanly; water is saved, and the environment is protected; ditch walls on the two sides are the same as those of a flat-bottom ditch, a ditch cover is the same as an original ditch cover, and only the flat bottom of the ditch bottom is changed into a groove-shaped or U-shaped ditch bottom; and the U-shaped concrete ditch bottom can be washed cleanly with small water in a concentrated way, and the dirt and the sewage are not left in the ditch.
一种U字型混凝土沟底，因为目前除管道外所有沟底横切面都是平底，不易冲洗沉淀物；本发明改进为沟底不是平底，而是两边呈坡状U字形或V字型，不易沉淀沙土、污物等在两边呈坡的沟底边，污物、污水集中在沟中心，能用较小的水冲洗污水、污物，且易冲洗干净；节水、环保；两边沟墙则与平底沟一样，沟盖也与原来的一样，只是沟底改平底为检槽型或U字型沟底；利于小水也能集中冲洗干净，不留污物、污水在沟中。
