Abstract:

施工车辆车轮带泥是我国道路扬尘污染控制面临的共性和突出问题。为在国内推广使用洗轮机提供技术依据,通过检测工地出口外道路积尘负荷来估算转轮式洗轮机对车轮带泥的冲洗效率,并以该洗轮机作为车轮带泥检测设备,检测和统计北京市车轮带泥量。结果表明,(1)转轮式洗轮机可以将工地出口外100m道路积尘负荷增量由64.4g/m2降至5.9g/m2,转轮式洗轮机对车轮带泥的冲洗效率大于90%;(2)渣土车和混凝土车车轮带泥量的平均值分别为5.1和2.2kg/车;(3)北京市未来车轮带泥量将超过8.8万t/a,施工车辆全部经过转轮式洗轮机冲洗后,车轮带泥量可削减7.9万t/a。建议在相关法律法规中以强制性条款落实施工车辆车轮带泥机械化冲洗要求。
