外海码头大直径钢管桩打桩施工技术

近几年,外海深水码头工程在国内沿海也得到大规模建设。而作为深水码头主要承载力的桩基,普遍采用螺旋焊缝大直径钢管桩。结合绿华山海上散货减载平台工程钢管桩打桩施工情况,扼要介绍大直径钢管桩施工主要技术,包括打桩准备、工艺流程和技术措施等,并介绍了钢管桩打桩的几点体会。

The Constructive Technology for Hammering the Steel Pipe Pile with Big Diameter in the Offshore

In recent years,many deep water terminals in the offshore have been constructed along the coast of China,and the spiral steel pipe pile with big diameter have been used widely as the main force-bearing pile foundation. In the light of the engineering of the L huashan load-reduction platform for bulk cargo,this paper introduces the main constructive technology for the steel pipe pile with big diameter,including preparation,technique procedure and technical measures. At last it introduces a few knowledge for hammering the steel pipe pile.
