混凝土井内钢顶管施工技术

Construction technology of steel pipe jacking in concrete well

介绍电厂灰坝降水钢顶管的施工设计与设计过程。采用自行设计的沉井内顶管,开创了沉井内钢顶管的先例,解决了沉井遇险不能下沉这一复杂问题。

This paper describes the design and construction of steel pipe jacking applied to the power plant. Adopting the self-designed pipe jacking inside the open caisson, we solved the problem of open caisson＇s sinking failure, which was the first application of steel pipe jacking in the open caisson.
