摘　　要： 介绍了中哈原油管道沼泽地区施工的情况,针对该工程在穿越阿亚古兹河沼泽和腾杰克河东西岸沼泽遇到的问题,采取了在管沟两侧50m范围内修筑拦水坝,每隔6m设置压重块,每焊接完3000m钢管就及时下沟等有效施工措施。对今后管道在沼泽地区施工有一定的指导意义。 This paper introduces the swamp pipeline construction course of Sino-Kazakhstan Oil Pipeline. Atasu-Alashankou Oil Pipeline,the first phase project of Sino-Kazakhstan Oil Pipeline,is 9622km in total length, approximately 960km in Kazakhstan, which will cross over the swampland around Ayaguz River and Tentek River. The swamp oil pipeline construction technique is as follows:(1) build up cofferdam on both sides of the pipe ditch (50 m-wide) to block off water; (2) install saddle weight al every 6 m interval and (3) lower down the welded pipe every 3000 m in length. The authors consider that the experience in swampland pipeline construction is valuable for similar pipeline project.
