摘要
陕京二线靖榆输气管道工程沙漠地段,由于土壤层为细粉砂,承载力极低,给挖沟及管道下沟施工带来困难,采用双侧沉管施工方法,解决了这一难题。该施工方法具有工艺简单、工期短、成本低等特点。文章介绍了双侧沉管施工方法及要点,并进行了经济效益分析。
In desert area of Jing-Yu Gas Pipeline of Second Shan-Jing Pipeline Project, soil layers belong tofine silty sand and have very low bearing capacity. It brings difficulties to trenching and pipe lowering construction.The problems are solved by lowering pipes on both sides. This construction method possesses the characteristics ofsimple process, short time period, low cost, and so forth. This paper describes the construction method of loweringpipes on both sides and its related key points, and conducts benefit analysis as well.
