The invention relates to a tube-fin type hard rock tunneling
machine, belongs to the field of
engineering machinery, and is used for solving the problems that according to an existing tunneling technology, the hard
rock cutting amount is large, the resources are wasted, the tunneling speed is slow, the tunneling cost is high, concrete
pipe sheets are purchased, and the service life of a building is only 100 years. A tunneling technology of the tube-fin type hard rock tunneling
machine provided by the invention comprises: a plurality of arc-shaped cutters at the front end of a cutter disc circumferentially
cut hard rock in a tunneling space into rock barrels; rock cores are taken out through water milling drills and a splitter in the center of the cutter disk; the rock barrels are
cut and sawn into
pipe sheets along the longitudinal direction; the
pipe sheets and rock bodies are horizontally separated through
cut saws in front of the center of the cutter disc; and a feeding and discharging channel at the rear end of the cutter disk is used for feeding cooling
cement pastes and discharging the pipe sheets and crushed rocks. Compared with the prior art, according to the tube-fin typehard rock tunneling
machine provided by the invention, the tunneling space hard rocks are manufactured into reinforced composite pipe sheets for lining tunneling rock walls, remained pipe sheets are directly sold or increase export revenue to offset the investment, the hard
rock cutting amount is small, the
resource utilization rate is high, the tunneling speed is fast, the tunneling cost is low,the project investment is low, and the service life of the building can reach to 1000 years.
