随着城市化经济的不断发展,城市规模不断扩大,城市道路地下管线的布设也日益复杂,各种管线平面、立面交叉布设,相互影响、相互制约。地下管线是城市建设与发展的基础设施,是城市维护其正常运作的血脉通道,地下管线运行好坏,对城市人民的生活和生产具有非常重要的影响,直接影响着城市生态环境。区域地下排水干管敷设不同于其他管线在工程上可以上下起伏,它依赖高差使污水无压自流运行。同时干管两侧辐射区域内的污水、雨水均通过连接管汇集到干管内排放,建设地下排水管线是城市基础设施建设中的重中之重,所以干管敷设的平面位置、立面高程在基础设施建设中应优先予以考虑,由于建设程序存在一定的局限性,地下管线经常出现排列混乱的局面,各自为政现象使城市道路多次开挖,不仅影响破坏了城市其他地下管线,也给城市居民的生活带来一定的影响。
With the continuous development of urbanized economy, the scale of cities is constantly expanding, and the layout of underground pipelines in urban roads is also increasingly complicated. Various pipelines and facades are laid across each other and influence and restrict each other. Underground pipeline is the infrastructure for urban construction and development. It is the urban artery to maintain its normal operation. The underground pipeline runs very well. It has a very important influence on the life and production of urban people and directly affects the urban ecological environment. Regional underground drainage pipe laying is different from other pipelines in engineering up and down ups and downs, it relies on elevation to make sewage run by gravity. At the same time, the sewage and rainwater in the radiation area on both sides of the main pipe are collected and discharged into the main pipe through the connecting pipe. The construction of the underground drainage pipelines is the most important task in the urban infrastructure construction. Therefore, Infrastructure construction should give priority to consideration. Due to the limitations of the construction procedure, underground pipelines often have disorderly arrangement. Due to their own merits, many excavations of urban roads have not only affected the destruction of other urban underground pipelines, but also to urban residents Have a certain impact on the life.
