Abstract

The invention discloses a crushing device for excavating stonework in fragmented rock formations and installation and use methods thereof. The fragmentation device includes a fragmentation drilling device, a hydraulic energy supply device and a walking system. The fragmentation drilling device includes Vertical drilling head, expander, positioning oil cylinder, fragmentation vibrator, vertical adjustment cylinder, fragmentation oil pump; hydraulic energy supply device, including fragmentation telescopic arm positioning, fragmentation telescopic arm support frame, fragmentation power supply Oil system, oil supply pipe; walking system, including generator set, operating room, walking crawler, walking system support frame, power line and control line. purpose of production efficiency. At present, the technical comparison and analysis of the stonework excavation in the fractured rock formation and the analysis of the shortcomings have found that the traditional drilling and blasting excavation process must use a large amount of pyrotechnic materials, and the safety factor is low.

Description

technical field [0001] The invention relates to the technical field of highway engineering construction, in particular to a device for excavating and fragmenting rock formations and a method for using the same. Background technique [0002] As domestic and international communities pay more and more attention to safety issues, the field of rock blasting has always been a major source of danger. How to reduce the safety risk caused by stone excavation is a focus in the construction field. The current development trend of stonework excavation in broken rock formations is roughly as follows: ①Due to the development of large-scale mechanization in the construction field of highway engineering, the mechanical operation methods for stonework excavation in broken rock formations are more and more widely used, which makes the fragmentation Large-scale mechanized production of rock excavation has become a trend; ②The current construction period of highway engineering is getting shor...
