摘要
本文介绍了大直径风动潜孔锤首次应用于含漂石砾砂层的预制桩沉桩施工,成功解决了复杂地层管桩沉桩难题的实例,对工程地质条件进行了分析,并对大直径预应力管桩引孔工艺及参数进行了论述。最后,讨论了潜孔锤沉桩过程中遇到的问题,并提出了相应的处理措施。
This text introduces the example the large diameter air operated down hole hammer was used in guidinghole for the first time, solving the difficult problem that the prestressed concrete pipe piling sank in the layer of gravel and boulders mixed together. Analyzed the engineering geological conditions and discussed the guide-hole technology and parameter. Finally, the text raised the corresponding measures which meet with the problem in the process of pile sinking.
