再生骨料透水砖在海绵城市建设中的应用

Application of recycled aggregate permeable brick in the construction of sponge city

随着我国城市化进程加快,城市内涝、水资源短缺、建筑垃圾露天堆放等问题严重影响我国的可持续发展。在国家大力倡导海绵城市建设及资源循环利用的契机下,选取通州区某地拆迁建筑垃圾进行成分分析及性能研究,加工成再生骨料,研究制备出透水性能好、符合国家标准的再生骨料透水砖。将再生骨料透水砖应用于某小区海绵化改造项目,与雨水花园、植草沟等其他低影响开发设施完美结合,达到了削减雨水径流、促进资源循环利用等一系列目标,实现了海绵城市设计、建设目标及区域内部的资源循环利用,具有良好的经济效益、社会效益和生态效益。

With the acceleration of urbanization in China,urban water logging,shortage of water resources,open stacking of construction waste and other problems seriously affect the sustainable development of China.Under the opportunity of state's strongly advocating of the sponge city construction and the recycling of resources,the construction waste of demolition in Tongzhou was selected to conduct the composition analysis and performance research,and the recycled aggregate was brick with good permeability with the national standards.The reclaimed aggregate permeable brick is applied to the sponge transformation project of a community in Tongzhou,It is perfectly combined with other low-impact development facilities such as rainwater garden and bioretention to cut the rainwater runoff,promote the resources recycling and a series of goals,achieve the goal sponge urban design,construction and regional internal recycling of resources,which brings a good economic benefit,social benefit and ecological benefit.
