大渡河安宁水电站深厚覆盖层勘探技术与方法
摘要:介绍了大渡河上游安宁水电站可研阶段河床深厚覆盖层勘探所用的技术与方法:φ130植物胶钻具钻进工艺、φ139厚壁套管跟管钻进工艺、多级跟管钻头钻进工艺;还介绍了覆盖层钻孔孔内旁压试验和原状砂样的采取技术。本阶段深厚覆盖层勘探中应用的技术与方法保证了勘探工作的圆满完成,为计算和设计提供了详实、可靠、全面的参数,同时也完善勘探技术与内容,提高了勘探水平,为今后的勘探工作作了相应的技术储备。
Abstract:This paper indicated that the deep cover exploration techniques and methods used in Dadu River anninghydropower feasibilities: φ130 plant gum drilling technology, φ139 thick-walled tube with the tube drilling technology, multi- level drill with drill pipe into the processes; and also described the cover drill hole next to the pressure tests and the original sand sample taken technology. The exploration in deep cover on the application of technologies and methods had ensured the successful completion of exploration work. For detailed calculations, designs, reliable and comprehensive parameters, It also improved exploration technology to improve the level of exploratinn for future work
