在当前城市发展建设的过程中,立体交叉道路出现得愈发频繁,但是道路立交以及铁路立交都属于最下层的道路,因此会形成洼地,纵向深度达到2m或者3m,在纵坡方面很大,一旦遇到暴雨的现象,就会产生积水的现象,相应的地下水位也要高出道路最低点很多,因此要想确保路基结构的良好,就要充分的考虑地下水位降水的问题,将其排放出去,这样才能有效地预防上述现象的发生。本文主要介绍了城市立交排水泵站的设计,满足相关室外排水的要求,设计了比较完善的排水系统,同时确保出水口的可靠性,这样即便是无条件的自流排水,也能得到全面的改善。
In the process of urban development and construction, the three-dimensional road crosses more and more frequently. However, road interchanges and railway interchanges belong to the lowest road. As a result, the depression will be formed with a vertical depth of 2m or 3m and a large vertical slope. Once the phenomenon of heavy rain, there will be a phenomenon of water accumulation, the corresponding groundwater level should be higher than the lowest point of the road a lot, so in order to ensure that the subgrade structure is good, we must fully consider the issue of groundwater level precipitation, its Discharge, so as to effectively prevent the occurrence of these phenomena. This paper introduces the design of urban overpass drainage pump station to meet the requirements of the relevant outdoor drainage, design a relatively complete drainage system, while ensuring the reliability of the outlet, so that even unconventional gravity drainage can be fully improved.
