摘要
对于一些较复杂的地层,存在钻进中护壁难的问题,文中的潜孔锤跟管钻进技术可以较好地解决此类问题,它针对松散、漏失、破碎等复杂的地层中钻进是有效的方法。文章中对一实际工程案例在桩基施工阶段的施工工艺进行了研究,全套筒潜孔锤跟管灌注桩基施工技术对于本项目的复杂地层是适用的,对于桩基的成孔的作用是显著的。对此类复杂地层的桩基成孔工艺可作为一个借鉴。
DTH hammer drilling technology,which is an effective method for drilling holes into pieces,leakage,loose and water sensitivity in complex stratum,can better solve the complex formation drilling wall in the difficult problem. The construction technology of a practical engineering case in the construction stage of pile foundation was studied.The construction technology of full sleeve DTH hammer and pipe grouting pile foundation was applicable to the complex formation of the project,and the effect on the pore forming of pile foundation was remarkable.The pore forming technology of pile foundation in this complex stratum can be used as a reference.
