摘要
本文主要研究目标依据宁波甬江大桥钻孔灌注桩中出现的糊钻问题进行讨论、改进,通过宁波甬江大桥工程桩基施工中对钻头的原理的研究和对外形(钻尖、切削尺、吸渣口等)的改进以及取得的经济效益,对于刮刀钻头在不同地层的有效性比较研究,分析、评价今后在类似地层(主要为沿海淤泥质压粘土比较厚的地区)的钻头设计,为最优化钻头设计提出解决方案以及提供数据支持。
This major research objectives are derived from Ningbo Bridge Yongjiang paste appeared bored pile drilling discuss issues to improve,Yongjiang by Ningbo Bridge Pile Foundation Construction of the principles of drill and shape（drill point,cutting ruler,smoking residue mouth,etc.） to improve and to achieve the economic benefits of,For Drag Bits in the Comparative Study of the effectiveness of different strata,Analysis and evaluation in the future in similar strata（mainly silt pressure for coastal areas of relatively thick clay） and bit design,in order to optimize the design of solutions to drill and to provide data to support
