摘　　要：为适应海绵城市的建设,改善路面硬化和缓解热岛效应,通过提高透水砖的透水速率,对传统透水砖进行结构改进,在渗漏孔基础上增加渗蓄水空腔以及连通管,缓解城市洪涝与水资源缺乏问题.通过与传统砖对比,此砖具有较完备的功能,集渗水蓄水以及回收雨水于一体.经实验室研究,砖体上水位积存100 mm时为液位采集系统报警水位,将该值作为城市洪涝时该结构砖体的最大透水速率,实验得最大透水速率23.9[mL/(min·cm^2)],远超出国家标准1.5[mL/(min·cm^2)].同时砖体强度也满足广场﹑步行街等露天承雨场所的应用,值得城市建设应用.In order to adapt to the construction of sponge city,improve the pavement hardening and alleviate the heat island effect,by improving the water permeable rate of permeable brick and the structure of the traditional permeable brick,increasing the seepage storage cavity and the connecting pipe on the seepage hole,it can alleviate the problem of the shortage of the city’s flood.Compared with the traditional brick,this brick has a complete function,including water seepage,water storage and recovery of rainwater.According to the laboratory study,the brick body water level accumulation which reaches to 100 mm is the alarming water level of liquid level collection system.Taking this value as the structure brick body’s maximum permeability rate when the city floods occur,the experimental maximum permeable rate reaches to 23.9[mL/(min·cm^2)],which far exceeds the national standard 1.5[mL/(min·cm^2)].At the same time,the strength of brick can also meet the application of open rain places such as square and pedestrian street.
