IMPACT OF PERMEABLE BRICK PAVEMENT ON STORMWATER RUNOFF THERMAL POLLUTION
-
摘要: 随着海绵城市的快速发展,透水砖铺装在实际工程中得到了广泛应用,但其对雨水径流热污染控制效果尚缺乏系统研究。采用人工模拟降雨方法,以不透水沥青路面为参考,研究了透水砖铺装系统对雨水径流温度的削减效果,具体包括透水砖铺装表面外排雨水径流温度、渗透出水温度以及各结构层的温度变化。实验结果表明:当重现期为5年一遇,透水砖铺装面层初始温度为35,42,47 ℃时,与不透水沥青相比,透水砖铺装面层外排径流温度可削减1.4~1.8 ℃,且面层初始温度越高,外排雨水径流温度越高,渗透出水温度也越高;透水砖铺装各结构层可削减渗透部分雨水径流的温度,渗透出水温度相对于径流温度降低3.5~5.2 ℃;降雨强度对透水砖面层外排雨水径流温度有显著影响,而对渗透出水温度影响较小。因此,透水砖铺装可有效削减雨水径流对城市水体的热污染。Abstract: With the rapid development of sponge city, permeable brick pavement has been widely used in practical engineering, but its impact on stormwater runoff thermal pollution is in shortage of systematic research. The artificial simulated rainfall method was used to study the stormwater runoff temperature reduction effect of the permeable brick paving system by using the impervious asphalt pavement as comparison. The research content include the runoff temperature of the permeable brick paving surface, the temperature of the permeate water, and the thermal transfer characteristics of each structural layer. The experimental results show that when P=5 a and the initial temperature of the permeable brick paving surface is 35, 42, 47 ℃, compared with impervious asphalt, the runoff temperature of the permeable brick paving surface can be reduced by 1.4~1.8 ℃, and the higher the initial temperature of the paving surface, the higher the temperature of the stormwater runoff, and the higher the temperature of the permeate water. The permeable brick paving structure layer can reduce the temperature of the permeable part of the stormwater runoff. The permeate water temperature is reduced by 3.5~4.9 ℃ compare to the runoff temperature. The rainfall return period has a significant effect on the runoff temperature, but its effect on the temperature of the permeate water is slight. Therefore, permeable brick paving can reduce urban stormwater runoff thermal pollution effectively.
