文章以南水北调配套工程隆华线供水工程中一个穿越公路顶管设计为例,详细介绍了顶管设计过程。顶管施工使输水管道在不中断公路交通情况下顺利穿越公路,满足输水要求。顶管设计在该类工程穿越中起到了很好的效果。该设计可以为其他配套输水管道穿越等级公路设计提供参考和依据。 The article takes the design of a pipe jacking through the highway in Longhua water supply project of South-North Water Diversion Project as an example, and introduces the design process of pipe jacking in detail. The pipe jacking construction enables the water pipe to cross the highway smoothly without interrupting the traffic of the highway to meet the water conveyance requirements. Pipe jacking design in this type of engineering has played a very good effect. The design can provide reference and basis for other supporting water pipeline crossing grade highway design.
