针对洛阳市雨水口泄水能力不足,造成道路积水、城市内涝、交通瘫痪等问题,成立专项QC小组。经过QC小组的调查分析,发现雨水口泄水能力不足的主要原因有道路坡度大、雨水口选材不当、雨水口数量不足、最低点未设置雨水口及杂物堵塞等。根据实际情况制定了实施对策,并按此对策进行积水点改造。结果表明,改造后的雨水口泄水能力显著提高,道路积水点数量明显减少,取得了较好的经济效益和社会效益。
For the lack of drainage capacity of the storm outlet in Luoyang, resulting in road water, urban waterlogging, traffic paralysis and other issues, set up a special QC team. After the QC group’s investigation and analysis, it was found that the main reasons for the lack of drainage capacity of the storm water outlet were large road gradient, improper rainwater outlet selection, inadequate number of rainwater outlets, and no rainwater outlets and debris clogging at the lowest point. According to the actual situation of the development of the implementation of countermeasures, and in accordance with this strategy for water point transformation. The results show that the drainage capacity of the improved rainwater outlet is significantly increased, the number of road water points is obviously reduced, and good economic and social benefits have been achieved.
