    Abstract:

    This article mainly introduces the design and verification test of ZHDN-SDR 150A high-frequency sonic drill, and provides theoretical basis and technical guidance for its application in the investigation and remediation of contaminated sites. The overall design scheme and the main performance parameters of the drill is discussed; meanwhile the structural design and technological innovation of the high-frequency sonic power head, the main components of the machine, and the auxiliary drilling tools are systematically analyzed. Verifying test was conducted for the drill in two different soil formations, and all parameters met the design requirements. The comparison of the verification results between the ZHDN-SDR 150A drill and similar ones at home and abroad shows that the drill stands at the domestically advanced level and runs neck and neck with international counterparts in terms of the main performance parameters and key equipment. The drill has prominent advantages with regard to vibration frequency, stratum applicability, and service life of auxiliary drilling tools, but has shortcomings such as decreasing drilling efficiency under the hyperthermal condition, scant intelligent and automation level. Therefore, it is necessary to further develop new materials with high temperature resistance and hardness, and to improve the remote wireless control system.
