摘要: 旋挖钻机所施工的地层千差万别,一般通过选用不同的旋挖钻斗来实现。通过工程实例研究不同地层中钻斗的合理选配,以及对现有的钻头进行有针对性的改造设计,不但可以提高机械施工效率,而且增加了钻头的使用寿命。

Abstract:  Foundation drilling in various soil and rock strata is achieved by using different drill bit and augers. This paper presents a case history of auger and drill bit selection so that different soil layers cab be effectively drilled. The paper also discusses the improvement of the existing drill bit so that the construction efficiency can be improved and the service life of the drill bit can be increased.
