管道在山区地形的选线要从施工难度,工程量大小、安全系数及经济方面上综合考虑。选择合理的管道敷设路线对日后的施工图设计及施工有重大作用,线路在保证管道埋深不小于最小埋深的同时,尽量采取浅挖的方式,如需削方则应加大埋深。水工保护措施在山区地段有着举足轻重的作用,其选择应由当地地质条件、坡度大小和气候等实际情况来决定。
Pipeline in the mountainous terrain of the route selection from the construction difficulty, project size, safety factor and economic aspects of comprehensive consideration. Choosing a reasonable pipeline laying route has a significant effect on the construction design and construction in the future. While ensuring that the pipeline depth is not less than the minimum buried depth, the shallow digging method should be adopted as far as possible. Hydraulic protection measures play an decisive role in the mountainous areas. The choice should be based on the actual conditions of the local geological conditions, slope size and climate.
