为提高水电站覆盖层地质勘查的质量和效率,研究基于声波钻机的成孔取样施工技术.通过分析声波钻机的工作原理及其在水电站覆盖层中的应用,结合具体的工程案例详细阐述了该技术的实施过程与效果.声波钻机利用高频振动与旋转钻进相结合的方式,有效降低了地层扰动,加快了钻进速度,并确保了样品的高质量.通过分析施工准备、成孔施工以及数据整理等环节,展示了声波钻机在复杂地质条件下的优越性能.研究表明,采用声波钻机进行覆盖层成孔取样可以显著提高取样质量和工作效率,为水电站设计提供了更可靠的地质依据.
Abstract
In order to improve the quality and efficiency of geological exploration of overburden of hydropower station,the drilling and sampling construction technology based on acoustic drilling rig is studied.By analyzing the working principle of acoustic drilling rig and its application in the overburden of hydropower station,the implementation process and effect of this technology are expounded in detail with specific engineering cases.Sonic drilling rig combines high-frequency vibration with rotary drilling,which effectively reduces formation disturbance,accelerates drilling speed and ensures high quality of samples.Through the analysis of construction preparation,hole-forming construction and data processing,the superior performance of acoustic drilling rig under complex geological conditions is demonstrated.The research shows that the sampling quality and working efficiency can be significantly improved by using acoustic drilling rig to sample overburden holes,which provides a more reliable geological basis for hydropower station design.
