浅析旧路改造中的排水问题及技术优化措施——以淄博市共青团路改造工程为例

在对共青团路现状管道、附属设施、雨水排河口和周边40余座小区进行了详细调查分析的基础上,在道路改造设计中通过增设雨水管道、优化雨水口布置、预留小区雨污分流接入口、结合海绵城市的设计理念的技术措施,较好的解决了共青团路积水的问题,并对影响市政道路排水设计的因素进行了总结。道路周边老旧小区排水设施不完善、雨水排河口处河道标高较浅、雨水管网及附属构筑物淤积破损严重,后期养管不力、极端天气等原因等都是造成道路积水的重要因素,综合考虑以上因素的影响,通过优化市政排水的设计等技术措施来减少道路积水,提高道路的使用年限,保证道路通畅。

Brief Analysis on Drainage Problems and Technical Optimization Measures in Reconstruction of Old Road

On the basis of detailed investigation and analysis on the present pipelines,ancillary facilities and rainwater discharge outfall of Gongqingtuan Road and its surrounding 40 housing estates,the waterlogging problem of Gongqingtuan Road has been solved by the technical measures of adding the rainwater pipeline,optimizing the rainwater inlet layout,reserving the rainwater and sewage separation inlets in housing estates and combining the design concept of sponge city in design of road reconstruction.And the factors affecting the drainage design of municipal road are summarized.The imperfect drainage facilities in the surrounding old housing estates,the more shallow elevation of river at rainwater outfall,the serious deposition damage of rainwater pipeline network and ancillary structures,the poor maintenance and management in later period,the extreme weather and the other reasons are all important factors causing the waterlogging of roads.According to the above affecting factors,the road waterlogging is decreased by the technical measures of optimizing the municipal drainage in order to improve the service life of road and to guarantee the smoothness of road.
