国道 205 深圳段改建工程给排水系统设计与施工国道 205 深圳段改建工程给排水系统设计与施工 【摘要】 国道 205 北起河北省秦皇岛市山海关地区，南至广东省深圳市，全长 3160 公里。该国道主要经过沿海地区，并且地势地貌复杂多样，沿海地区雨水较充足，夏季雨水尤其充沛，山体滑坡等自然灾害常常发生。较多的水源要充分利用，否则就造成浪费。但水体太多若排水不畅将会对国道 205 的运输功能造成影响。此次主要探讨深圳地区的国道 205 的给排水设计方案，国道 205 深圳段起点为龙岗布吉，终点为深圳和惠州交界处，全长 36 公里。该路段交通繁忙，周边建筑密集，地下管线种类繁多，并要在设计时考虑与地铁 3 号线管线的接驳，这都给国道 205 的给排水设计带来较大的难度，本文对设计与施工过程中所遇到的一些问题进行总结。给各位同行以参考。 【关键词】国道 205，给排水设计，合理规划 【 abstract 】 national highway 205 from the hebei province qinhuangdao shanhaiguan area, south to guangdong province shenzhen, 3160 kilometers. The national highway main after coastal areas, topography and landforms complicated coastal areas, the rain is enough, the summer rain especially energetic, landslides and other natural disasters happen very often. More water should make full use of, or otherwise it will cause waste. But if too much water will be poor drainage of the 205 national highway transportation function the influence. The mainly discusses the national highway 205 in shenzhen area of the water supply and drainage design scheme, the national road 205 shenzhen section starting point for longgang buji, end point in shenzhen and huizhou junction, the 36 kilometers. The road traffic is busy, the buildings around dense, underground pipelines varieties, and to the design consideration and metro line 3 of the pipeline connecting the, the national highway 205 of the water supply and drainage design to bring greater difficulty, in this paper, the design...
