随着虹吸作用在桥面排水中取得突破,虹吸排水已在屋面排水和桥面排水中得以应用,解决了城市排水的重大难题。雨水斗是虹吸排水的重要部件,本文通过对雨水斗在屋面桥面虹吸式排水中作用原理分析,将其引入到路面虹吸式排水中,设计路面排水结构模型,模拟出路面虹吸排水压力变化曲线。 With the siphon effect in the bridge deck drainage breakthrough, siphon drainage has been applied in the roof drainage and bridge deck drainage, to solve the major problems of urban drainage. Rain bucket is an important component of siphon drainage. In this paper, through the principle analysis of rain bucket in siphon drainage of roof deck, this paper introduces it into the siphon drainage of pavement, designs the drainage structure model of pavement, simulates the change curve of siphon drainage pressure .
