过河供水管道水平定向钻穿越工程的设计与施工

Design and Construction of Water Supply Pipeline Crossing River Project with Horizontal Directional Drilling Technology

开平大桥旁的过河供水管道工程横跨潭江主航道,管材采用DN800的PE管,管道总长为594.8m,为了保证航路畅通并保护两岸长堤的优美风景,确定采用水平导向钻穿越施工法,避免了开挖施工带来的交通封锁和对现有市政设施的破坏,且施工安全、工期短、成本低,可为相关工程施工提供借鉴。

The water supply pipeline beside the Kaiping Bridge passes crossing the main channel of Tanjiang River. The pipeline is DN 800 PE, and the total length is 594.8 m. In order to ensure an unimpeded water way and protect the beautiful landscape along the river, it was determined that horizontal directional drilling technology was used to avoid the traffic control and damage to existing municipal facilities caused by excavation construction. The project has safe construction, short construction period and low cost, providing reference for construction of similar engineering.
