Urban underpass drainage system optimization method
The invention relates to an urban underpass drainage system optimization method. The optimization method comprises the following steps of constructing a solid terrain digital model of an area where an underpass is located by matching an existing topographic map with field survey, dividing the solid terrain digital model into three types of drainage areas according to a catchment area and the height of a horizontal plane where the solid terrain digital model is located, dividing the solid terrain digital model into a high drainage area group, a middle drainage area group and a low drainage area group, optimizing and independently arranging the existing drainage main pipeline, arranging three groups of independent high-area independent main pipeline groups, middle-area independent main pipeline groups and high-area independent main pipeline groups on the basis of the existing main pipeline, counting the existing water collecting wells and water pump stations, optimizing the existing water collecting wells and water pump stations, and improving the pump-to-machine ratio of the existing water pumping stations. The optimization method has the advantages that independent drainage is performed after optimization, backflow of accumulated water due to accumulated water heights of different areas is avoided, flushing of each pipeline is facilitated, continuous smoothness of the pipelines is guaranteed, a good adjusting effect is achieved under the condition of large rainfall, and accumulation and water seepage of low-area water levels are reduced.
本发明涉及城市下穿地道排水系统优化方法，从现有地形图配合实地勘测构建下穿地道所处区域的实体地形数字模型，将所述实体地形数字模型根据汇水面积和所处水平面高度划分三类排水区域，将其分为高排水区组、中排水区组、低排水区组，优化独立现有排水主管道，在现有主管道基础上设立三组独立的高区域独立主管道组、中区域独立主管道组、高区域独立主管道组，统计现有集水井和水泵站，对现有集水井和水泵站进行优化，改善现有水泵站的泵机配比。有益效果在于：优化后进行独立排水，避免不同区位的积水高度而实现倒灌积水，有利于各个管道的冲洗，保障了管道的持续畅通，对于雨量较大的情况有较好的调节作用，减少低区水位的积存、渗水现象。
