YSZ-50型声频振动钻机的研制

Development of YSZ-50 Sonic Drilling Rig

摘要:

声频振动钻进技术是近年来发展较快的新型钻探技术，主要利用声频振动头产生的高频振动力，引起钻柱系统的共振，并带来土体的局部液化，实现快速钻进和高质量地质取样。主要介绍了YSZ-50型声频振动钻机的结构设计、主要技术参数和特点以及取样试验。

Abstract:

Sonic drilling technology is a newly developed drilling technique. High frequency vibration generated by the sonic head is mainly used to produce the resonance of the drilling string system and the liquefaction of soil layers, then fast drilling and geotechnical sampling of high quality are realized. The structure design, main technical parameters, the features and sampling test of the YSZ-50 sonic drilling rig are introduced in this paper.
