全液压车载钻机在缺水地区化探取样中的应用研究

Application of Full-hydraulic Truck Driller with Automobile Chassis in Drought

摘要:

针对干旱、半干旱地区缺水的特点，结合化探取样的要求，采用全液压车载钻机空气潜孔锤钻进工艺。结合车载钻机在西北部地区化探取样工作中遇到的问题，由此采取的有效措施、总结取得的经验成果，为该地区工作的进一步开展提供一些参考；同时使空气正反循环工艺在浅层取样的应用上更加完善，更加成熟，给本行业的工程技术人员提供一些思路。

Abstract:

This paper discusses the application of full-hydraulic track driller with automobile chassis in the arid and semiarid areas. According to the geochemical sampling requirement， full-hydraulic air-driven hammer drilling technology was adopted. The paper summarizes the experience， which made the drilling technology with air positive circulation and reverse circulation more perfect.
