The selection of gutter products in the design of road drainage system, the selection of products to take into account the urban residential sewage volume, industrial wastewater volume and rainwater volume.

The bearing capacity is designed in the outdoor drainage system, and the load of vehicles on the path groove surface must be considered.

Water, nature of the serious environmental pollution in China, in the rain, sewage tend diversification, high content of corrosive chemical element, industrial sewage, the sewage of traditional cement drainage, cast iron pipes have greatly corrosive, collapse, leakage caused by long-term use, caused serious influence to the urban environment. The resin concrete material has good corrosion resistance to heavily polluted water. In the immersion test of 20% H2SO4 solution (strong acid) and 20% NaOH solution (strong alkali), there is no corrosion phenomenon in resin concrete drainage ditch. The experimental data show that the product has good corrosion resistance.

Road landscape requirements in specific areas of the city, environmental beautification is a necessary condition in the construction of the city, road drainage system should be based on the overall requirements of urban design, the choice of drainage ditch products, and urban construction matching.
