大直径顶管在水利输水工程中的运用

Application of large diameter pipe jacking in water transmission project

丰县大沙河水源地水质提升工程中引水地涵的输水管道部分通过采用大直径、长距离顶管方式穿越大沙河水源地,既保护了大沙河水源地,也满足了设计输水要求。文章以该项目为例,系统地分析和探讨了输水管道的设计思路,并对管道的水力计算及结构计算的相关原理进行了简单的介绍,通过本工程的成功经验,为大直径顶管在水利工程中的应用提供借鉴。

In the water quality improvement project of Dasha River water source area in Fengxian county, the water conveyance pipeline of the diversion culvert passes through the Dasha River water source area through large-diameter and long-distance pipe jacking, which not only protects the Dasha River water source area, but also meets the requirements of design water conveyance. Taking this project for example, the paper systematically analyzes and discusses the design idea of water transmission pipeline, and simply introduces the relevant principles of hydraulic calculation and structural calculation of the pipeline. Through the successful experience of this project, it provides a reference for the application of large-diameter pipe jacking in water conservancy projects.
