顶管施工技术是一种对环境影响很少的施工方法,在实施时不需开挖上面土体,减少了开挖放坡带来的危险性,文章对顶管施工技术及顶管技术的优点、应用范围、工作原理进行了介绍,论述了顶管施工中顶力、方向控制、制止正面塌方等关键技术与措施,以某供水管线工程为例,对顶管工程施工工艺进行了详细介绍,为今后同类顶管施工提供了借鉴。
Pipe jacking construction technology is a kind of construction method that has little impact on the environment. It is unnecessary to excavate the above soil during the implementation and reduce the danger brought by excavation and grading. This paper analyzes the construction technology of pipe jacking and pipe jacking Advantages, application range and working principle are introduced. The key technologies and measures such as jacking force, direction control and frontal collapse prevention are discussed. Taking a water supply pipeline project as an example, the construction technology of the jacking pipe project is introduced in detail , Which provides a reference for similar pipe jacking construction in the future.
