顶管施工是继盾构施工之后而发展起来的一种地下管道施工方法,它不需要开挖面层,并且能够穿越公路、铁道、河川、地面建筑物、地下构筑物以及各种地下管线等。顶管施工已随城市建设越来越普及,已发展成为一门非开挖施工技术,应用领域也越来越宽;目前,机械式顶管施工已在沿海城市得到普及,但在特定的土质条件下,手掘式顶管施工仍是现今管道施工中普遍采用的施工方式。 Pipe jacking construction is an underground pipeline construction method developed after the shield construction. It does not need to excavate the surface layer, and can cross roads, railways, rivers, ground buildings, underground structures and various underground pipelines. Pipe jacking construction has become more and more popular with the construction of the city and has developed into a trenchless construction technology with more and more applications. At present, the construction of mechanical pipe jacking has been popularized in the coastal cities. However, Under the conditions, hand-jacking pipe jacking construction is still commonly used in the construction of the pipeline construction methods.
