Study On Rainwater Use Technology In Highway Service Area

This dissertation aims to the highway service roofing, concrete and asphalt pavement, no-parking area etc impervious to the rain triggered off the surface, making the rain infiltration channel short confluence time, rain flood peak value increases, leading to local poor drainage appear to company take water phenomenon, bring a lot of inconvenience of personnel, based on'rain comprehensive utilization'and sustainable water environmental system construction as the target, combining xinyang highway service area. This paper focuses on analyzing the highway service rainwater utilization technology. The main results of the study are as follows:1. Throughing the soil science, hydrology, engineering theory research, this paper analyzes the key factor to provide theoretical support for the late rainwater using technology.2. Aiming at xinyang highway service, formulated overall scheme formulated the technology of rainwater using. Strengthening infiltration, Green roof, Sunken type green space, Seepage type vegetation shallow groove, Penetration drainage integration is the main technology of rainwater using. And analyzed each technology to the applicable range and influence for rainwater utilization. After the engineering, xinyang highway service service area after rainwater to use after a comprehensive runoff coefficient can be reduced to the 0.57 than 0.67 before.3. Throughing the analysis of theoretical potential and can be realizing rainwater resources, to realize recycling project to provide necessary rainwater resources, the theoretical potential rainwater resources of xinyang highway service is 1100mm, as potential enormous area suitabled for the development and utilization of rainwater resources.4. Using the rainwater, required, system optimization calculation methods researchs rain storage facilities of xinyang highway service. After each stored in the interval of two rain all used is considered as optimization. It is concluded that the storage facilities scale of xinyang highway service recycled three days rainwater, that is 800 m3, corresponding rainfall H is 12.8 mm, rain water storage facilities of the full number N is 38, Average annual gather rainwater is 36178 m3.
