Leakageproof flow-concentrating trough

The utility model discloses a leakage-proof flow-concentrating trough used for the road, comprising a trough body and trough edges. The trough edges are arranged on the two long side walls of trough body; the trough edges and the trough body can have an integral structure; the cross-section of the trough body can be arc-shaped or trapezia; the bottom surface of the trough body and the side walls of the trough body are connected together in the curve transition way; the structure of the flow-concentrating trough concretely is saurer material and water-proof agent-glass fabric-saurer material-glass fabric. The utility model has the advantages that the leakage-proof flow-concentrating trough used for the road which has beautiful appearance, convenient maintenance and high intensity is free from crack, leakage, the invasion of heterogyna and rats.
