摘要
综合管廊是国家今后重点建设的市政项目,实际工程中部分管线由于本身特性或其它原因,比如雨污水管由于自身重力流特性,许多综合管廊不将其纳入。通过对苏州新区建有综合管廊的道路中综合管线的分析,总结了一些管线综合设计要点:管线不直接敷设在综合管廊上;管线必须穿越管廊时尽可能穿越综合管廊主沟和下凹处等覆土较深区域,同时不穿越综合管廊下部;管线须穿越综合管廊引出口时,引出口调整一定坡度获得一定地下空间;上下游标高限制时,雨污水管可设置倒虹或交叉井,这些要点供以后工程建设设计和参考。
The utility tunnel is a municipal project of the national key construction in the future. The partial pipelines will be not included into many utility tunnels in the practical projects because of the characters or the other reasons, such as the gravity flow characters of rainwater and sewage pipes. According to the analysis of the integrated pipelines in the road with the utility tunnel built in Suzhou New District, this paper summarizes the integrated design essentials of some pipelines. The pipelines cannot be directly laid on the utility tunnel. The pipelines cross the main ditch and the lower concave covered with deep soil of the utility tunnel as far as possible when the pipelines have to cross the utility tunnel. At the same time, the pipelines cannot cross the bottom of utility tunnel. When the pipelines have to cross the outlet of utility tunnel, the outlet is adjusted to a certain slope in order to obtain a certain underground space. When the upstream and downstream elevations are limited, the rainwater and sewage pipelines can be installed with the inverted siphon well or crossover well. These essentials can be referred for the design and construction of the similar projects.
