随着社会经济发展,城市规模在不断的扩大,与城市配套的各种地下、地上的管线和建筑规模也随之不断增加。管线在穿越河流地段通常采用顶管施工技术,因此穿越河流地段顶管工程的勘察设计工作也越来越多。本文结合南水北调配套工程漯河市三水厂支线管道穿沙河顶管工程为例,探讨了穿越河流顶管工程勘察设计工作的重点。
With the development of society and economy, the scale of cities is constantly expanding, and the underground pipelines and buildings on the ground supporting cities are also increasing in size. Pipelines often use pipe jacking technology when crossing the river. Therefore, there are more and more survey and design work for pipe jacking projects across the river. In this paper, taking the case of Shahe pipe jacking project of branch pipelines of Luohe Sanshui Plant in South-North Water Diversion Project as an example, the emphases of investigation and design of pipe jacking through rivers are discussed.
