The Study Of Huhehaote To Baotou Highway Drainage Design

In Highway, The major source of water are groundwater, surface water and meteoric. The water is not only have affect to the safety of road traffic, and will shorten the life of the road. The water on the road face cause road slippery, vehicle skid,make the braking distance increases. The water in the road damage to the roadbed, pavement structure, reduce the useful life of the road. How to solve the problem of water damage on the road is the main target of this paper.In this paper, based on the highway from huhehaote to baotou, depth study on the highway area huhehaote to baotou hydrogeology, water forming principle. And make a unified inductive, arrange, analysis about precipitation, groundwater and surface water invasion on the road. Base on the finishing of the existing drainage concept, The highway from huhehaote to baotou four-lane to eight-lane highway design process using specific practical, adaptable programs. It have better representation and practicality.On the basis of research about the present specification and hydrology, hydraulics To investigations, calculations and analysis about the design parameters on catchment area, the design return period of rainfall. Calculate the ditches and drains size, slope, length, curb with centralized drainage opening interval data. Reference to the latest calculation methods evaporation ponds. To determined the interchange circle evaporation pond size. Be studied on the domestic and foreign advanced design concepts, In a more advanced way to systematic analysis of the entire highway environment Hubao highway all major drainage patterns...
