城市广场、人行步道采用透水地面的探讨

Approach to Permeable Surface used on Urban Square and Pedestrian Walk

针对目前城市市区地面普遍采用硬化铺砌,以致雨水径流入管道,无法向地下渗透,从而造成地下水位下降、管网和泵站压力增大以及管道出口河道水位升高引发倒灌等问题,研讨解决问题的对策,并提出一系列具体措施。使城市的天然降水顺利渗透到地下,补充地下水,逐步达到生态城市的标准。

ITo counter the following problems: hardening paving is generally used now on the surface of urban district so that the rainfall runoff flows into piping without seeping into underground to cause the back flow due to drop of the underground level, increase of the pressure of piping network and pumping station as well as the raise of the river course level at piping outlet. It studies on the countermeasure for solving the problems and puts forward a series of concrete measures so that the urban natural drop could smoothly seep to the underground for supplying the underground water to reach gradually the standard of eco city.
