Drainage blind ditch and cover plate for reducing surface accumulated water

Technical Field

The utility model relates to a field of road surface drainage specifically is a reduce drainage french drain and apron of surface gathered water.

Background

The water supply and drainage system is an essential infrastructure for ensuring the drainage of urban ground water, preventing and treating urban water pollution and making the protection of urban water resources in virtuous circle. Due to the functions and characteristics of the urban water supply and drainage system facilities, the urban water supply and drainage system facilities have large engineering scale, large investment amount, large construction difficulty, long construction period and large energy and resources consumption in operation. Before the social economy is fully developed, the city is not easy to have perfect drainage facilities and good water environment. Most of the water pollution is caused by excessive utilization of natural purification capacity. The project researches an outdoor ecological construction water supply and drainage system technology to solve the related problems.

The rainfall runoff refers to rainwater and ice and snow melting water which run on the ground, and is also called the rainfall runoff. The quality of precipitation runoff is related to the surface condition of the runoff. Generally cleaner, but the initial rainwater runoff is dirty.
