摘要:: 手掘式顶管施工技术以其低廉的成本和优良的施工质量被广泛应用于国内外许多管道工程的建设中。文章结合兰银输气管道工程2C、3A标段的等级公路穿越施工实践,介绍了手掘式顶管技术应用的地质条件以及相关施工技术,包括千斤顶的选择、测量放线及工作坑的开挖、设备的安装、套管顶进及作业测量、偏差和纠正措施及检测等,进一步丰富了在不同地质条件下进行手掘式顶管施工的经验。
Owing to the low cost and excellent construction quality, the manual pipe pushing construction technique is widely used in many pipeline projects at home and abroad. Combined with the construction practice of 2C and 3A bidding sections of Lan-Yin Gas Transmission Pipeline, the applicative geological conditions and relevant construction techniques including jack selection, measuring and route setting out, working pit excavation,equipment installation, casing pushing operation, measurement, deviation and rectification as well as detection are described, which enrich the experience of manual pipe pushing construction technique under different geological conditions.
