顶管进出洞及穿越重要构建筑物关键技术研究

Research on key construction technology of pipe jacking breaking-in,breaking-out and crossing important structures

顶管作为非开挖工程中重要的一项工程技术,在城市中的应用愈加广泛。城市中复杂的工程环境使得人们对顶管的施工提出更加严格的要求,更加安全、更加高效、对周边环境的影响更加小。故依托杭州市取水口上移工程(二期)项目中的顶管施工工程,对顶管进出洞和穿越构建筑物等关键施工技术进行研究,为以后类似工程提供经验和借鉴。

As an important engineering technology in trenchless engineering,pipe jacking is more and more widely used in cities.The complex engineering environment in the city makes people put forward stricter requirements for pipe jacking construction,which is safer,more efficient and has less impact on the surrounding environment.Therefore,relying on the pipe jacking construction project of Hangzhou Water Intake Upward Moving Project(PhaseⅡ),the key construction technologies such as pipe jacking breaking-in,breaking-out and crossing structures are studied to provide experience and reference for similar projects in the future.
