Research on the development and application of large-diameter hard rock drilling tool for mountainous areas
摘要
Abstract
Aiming at the problem of large-diameter hard rock hole formation in the construction of transmission line tower foundations under complex geological conditions in mountainous areas,and the limitation of construction equipment selection due to the lack of transportation roads,a large-diameter hard rock drilling tool suitable for cableway transportation conditions in mountainous areas was developed to solve the difficulty of large-diameter hard rock hole formation,improve construction efficiency and safety.This modularly designed drilling tool has high-efficiency rock-breaking capability and vertical spiral slag discharge function,and can achieve mechanized hole formation in hard rock geological conditions of 40～65 MPa.Through the optimization of drilling tool structure and rock-breaking slag discharge principle,and customized design in combination with the characteristics of cableway transportation.After on-site tests,it is showed that this drilling tool has reliable performance and effectively solves the problem of mechanized hole formation in hard rock geological conditions,and verified the feasibility and effectiveness of the design concept.关键词
