The invention belongs to the technical field of full-section
rock tunnel boring machines, and particularly provides a steel-concrete combined
pipe piece supporting
open type rock tunnel boring
machine which comprises a shield, an excavation
system, a steel-concrete combined steel
pipe piece, a supporting and propelling
system, a
belt conveyor slag removal
system and a
pipe piece assembling mechanism, and the excavation system, the steel-concrete combined steel pipe piece, the supporting and propelling system, the
belt conveyor slag removal system and the pipe piece assembling mechanism are installed in the shield. The excavation system is used for tunneling and excavating the tunnel; the excavation system and the shield are mutually connected to form heading
machine main equipment; the steel-concrete combined steel pipe sheets are used for stably excavating a channel and supporting a
tunnel wall; the supporting and propelling system is used for supporting the heading
machine main equipment and adjusting the heading posture of the heading machine main equipment; the
belt conveyor slag removal system is used for conveying broken rocks generated in the tunneling process of the excavation system to the outside of the tunnel; the pipe piece assembling mechanism is used for grabbing and conveying steel-concrete combined steel pipe pieces or steel arches. The steel-concrete combined steel pipe pieces are arranged, the structure is reinforced only through concrete, a thin shell is used for replacing a thick steel plate, and the overall light weight effect is achieved.
