【摘要】 城市化带来的诸多变化当中,地面硬化使承接雨水的下垫面发生显著改变是其中之一。随之而来的问题就是雨水不能及时下渗、地面积水、城市排水和防洪体系的负担加重。同时地面硬化也是城市热岛效应产生的重要原因之一本文试图从城市地面硬化后的排水设计着手,把各类建筑物都作为集水面,通过建筑物的屋面、透水性铺装的地面和透水性路面等工程的设计环节,把雨水纳入集水、储水、利用的资源节约型、环境友好型的运行体系和有序管理中,使雨水作为一种资源得到合理的利用。为此,提出以下设计思路和方案：1、雨水储存可分为资源型储水和生态型储水,各有针对性的设计方案。雨水收集后应按照先储后排的原则进行处理。2、城市道路横断面设计中应采用绿化带下沉的凹形设计,雨水通过绿化带过滤后以溢流的方式进入雨水利用系统。3、新建城市区域和某些特定开发区域应实行雨水自平衡的设计机制,并通过雨水截流、利用等设施和立体绿化等措施消纳雨水。4、改进雨水的收集、排放方式的设计方案,使雨水管网既可以作为过渡性的雨水存储设施,又可以作为雨水利用的调运设施,实现排水、储水一体化设计5、应当建立雨水收集、存储和利用的政府、社会、市民三位体的分级实施的责任体系。6、对雨水收集、利用的公共政策和相关技术法规提出可以改进的建议。更多还原

【Abstract】 Significant variation of under layer surface caused by hardened ground is one of great changes brought by urbanization.The coming problems include rainwater infiltration, ground seeper and increasing burden of flood control system. Hardened ground is also an important reason of heat island effectIn this article, the roof of buildings, surface of pavement and ground are regarded as rainwater-collecting area, and the rainwater considered as a resource is put into resource-saving and environment-friendly operation system of rainwater collection, storage for utilization in urban. For the purpose, the following design idea and scheme are obtained in this study.1. Rainwater storage is divided into resource-based storage and ecotype storage with pertinent scheme. After collected, water should be stored first and then drained.2. Concave design aiming at greenbelt subsidence should be applied in design for cross-section of urban road. After greenbelt filtration, rainwater overflows into rainwater utilization system. 3. Design mechanism of rainwater self-balance should be carried out in new-built districts and some specific development zones, and water should be consumed by facilities and design mechanismres of closure, utilization and three-dimensional afforestation.4. The scheme for rainwater collection is designed. Especially to realize integrated design of water drainage and storage, urban rainwater pipe network can be not only present drainage facilities, but also transitional storage facilities and transportation facilities.5. Responsibility system responsible and implemented by government, society and citizen is proposed for water collection, storage and utilization.6. Suggestion for public policy and relative technical regulations of water collection and utilization is carried out.更多还原
