浅谈深埋大直径双排管施工技术

土压式顶管施工是管道施工中较常见的方法。该施工方法对土质的适应性强,不需要采用其它辅助施工手段,因此适用于天津软土地质条件下深埋大直径双排管工程的施工。本文结合工程实际介绍了在具体工程中的土压式顶管施工工艺、系统布置及参数控制。

On the Construction Technology of Deep Buried Large Diameter Double Pipes

The earth pressure balance pipe jacking construction is a more common method of pipeline construction. This construction method adaptable to the soil, without the use of other auxiliary construction means, therefore it is suitable to soft soil deep buried large diameter pipes engineering in Tianjin geological condition. Combined with the engineering practice, this paper introduces the earth pressure balance pipe jacking construction technology, system layout and parameter control in the concrete project.
