摘要:

声频振动取样技术是近年发展速度较快的适用于土壤环境地质取样的新型取样技术，是利用声频振动头（激振器）内对称分布于钻机输出轴两侧的两个激振锤同步旋转产生的高频振动力（50~200 Hz）振动钻杆或外套管钻进。主要介绍了TGSD-50型声频振动取样钻机的结构设计、主要技术参数和特点。

Abstract:

Sonic drilling coring is a relatively new exploration technique for drilling and sampling application in the fields of soil environmental and geo-technical exploration. It uses high frequency vibrations (50~200 Hz) generated by 2 symmetrical rollers in the sonic head (oscillator) to vibrate drill pipe or outer casing for drilling. The rollers’ vibration is synchronized to ensure that the vibration is transmitted vertically down the drill string to the bit. The paper introduced TGSD-50 sonic drilling coring rig about the structure design, main technical parameters and the features.
