综合管廊近距离密集顶涵上穿地铁既有线工程关键技术

KEY TECHNOLOGY FOR PIPELINE COLLIGATE ALURE PASSING THROUGH ABOVE EXISTING SUBWAY LINE CLOSELY AND INTENSELY BY METHOD OF JACKING CULVERT

北京市通州区某新区有3条综合管廊近距离密集顶涵上穿地铁既有线。经前期充分技术论证,与其他穿越地铁工程进行统筹协调配合,顶涵过程实施精细化控制,3条综合管廊顺利实现安全上穿地铁既有线。

There are three pipeline colligate alures passing through above existing subway line closely and intensely by the method of jacking culvert in a new area of Tongzhou in Beijing. It implements smoothly that three pipeline colligate alures passing through above existing subway line, by sufficient technical argumentation in the early stage, coordination and co-ordination with other crossing subway projects and fine control of jacking culvert implementation process.
