摘要
气动潜孔锤钻机在微型桩基施工中运用效果很好,特别是在第四系松散地层和卵砾石层等复杂地层中,采用跟管钻进方法很好地解决了进尺难等问题,并有效地预防孔内事故的发生。气动潜孔锤钻机相比普通回转钻机更加方便、快捷、高效。
Pneumatic DTH hammer drill has been used in the construction of micro-pile foundation with good effect. Especially in the complex strata such as Quaternary loose stratum and gravel stratum,pipe-following drilling method has solved the problem of difficult footage and effectively prevented the occurrence of accidents in the hole. Pneumatic DTH hammer drilling machine is more convenient,faster and more efficient than ordinary rotary drilling rig.
