摘要
Abstract
Currently,the XY series spindle drills are used for engineering geological survey as the main drilling machine,which is often difficult to relocate and time-consuming when operating in remote,inconvenient transportation and complex surface en-vironments.In comparison with spindle drills,portable drills not only considers the portability but also ensures sufficient feed-ing stroke.In the past decade,they have attracted much attention and have become the preferred model for many geological survey units.Portable drills can achieve high economic benefits when applied to hard and complete formations.However,in near surface Quaternary overburden,portable drills often have problems such as insufficient torque and ability to deal with acci-dents due to frequent formation shrinkage and sticking.This paper focuses on the adaptability of portable drills in overburden drilling,and adopts a modular design to modify the design of portable drills.By improving the structure of power head and adding a casing oscillator at borehole opening,new portable drill has the functions of vibration drilling and drilling with simul-taneous casing,greatly improving its coring drilling ability in complex formations such as Quaternary loose overburden.关键词
