摘　　要：环境取样是地层污染调查及风险评估的重点,取样工艺和配套的取样钻具对取样的质量起着至关重要的作用。全液压直推式低频环保取样钻机及其配套的直推式取样钻具,采用静压和冲击锤冲击钻进,配备相应的直推式取样钻具和钻探工艺,钻进过程中实现不提钻取土样,无水钻进,有效解决了取样量不足、样品扰动和污染的问题。介绍直推式低频液压冲击环保取样钻机钻具结构、钻进工艺和应用等,为后期取样工艺和钻具的研发与创新研究工作提供参考。Environmental sampling is the key point for investigation and risk assessment of formation pollution. To keep the soil samples intact, undisturbed and uncontaminated,the sampling process and the associated sampling drilling tools play a vital role in sampling quality. The fullhydraulic direct-push low-frequency environmental sampling drilling rig and its associated direct-push sampling drilling tools use hydrostatic and percussive hammers for percussive drilling,and with the corresponding direct-push sampling drilling tools and drilling technology,soil sampling without pulling up the rig during drilling and water-free drilling are achieved, effectively solving the problems of insufficient sampling amount, sample disturbance and contamination.The direct-push low-frequency hydraulic percussive environmental sampling drilling rig, drilling tool structure,drilling technology and application are introduce, which can provide reference for the later development and innovation research of sampling technology and drilling tools.
