大型冷弯钢板桩“半屏风式”沉桩工艺

Half-screen pile-sinking technology of large size steel-sheet pile

以中海油渤海湾生产支持基地工程为例,介绍了一种采用大型振动锤、"半屏风式"钢板桩沉桩工艺,有效地克服了大型冷弯钢板桩因桩身扭转、带桩等因素造成的各种施工困难,证明了该工艺可行、高效。

Taking the project of the production supporting base at Bohai gulf of CPOE for example, we introduce the pile sinking technology using the large vibratory hammer and the half-screen, which resolve various kinds of difficulties caused by the pile twisting and pile dragging steel-sheet piles. The technology in the construction of the large-size cold bending is proved to be feasible and efficient.
