To overcome common challenges in conventional drilling operations—such as poor adaptability to benching methods, difficulty in invert excavation, low blasting efficiency, poor contour control, and inadequate overbreak/underbreak management—UNIROC provides a range of drill jumbo solutions suitable for full-face excavation, micro-bench, bench method, invert excavation, dowel hole drilling, and forepoling tube installation.

To address the issues of high labor intensity, low efficiency, significant safety risks, poor adaptability to benching in weak rock masses, and difficulties in manual stemming, UNIROC provides a mechanized solution integrating arch erection, face stemming, dowel hole drilling, quality inspection, and high-altitude auxiliary operations.

To tackle issues in conventional bolting operations—including restricted working space, high labor intensity in manual drilling, low efficiency in dowel hole and systematic bolt hole drilling, and difficulties in invert and medium-deep hole construction—UNIROC offers articulated-boom bolting equipment for mechanized installation of systematic bolts, dowels, forepoling tubes, pipe roofing, and medium-deep anchor holes.

To overcome challenges in conventional shotcreting—such as high manual labor demand, difficult rebound control, inconsistent shotcrete quality, troublesome equipment maintenance, and harsh working environments—UNIROC provides wet-mix shotcreting solutions suitable for both large-span and small-cross-section tunnels, enhancing spraying productivity, shotcrete quality, and worksite safety.

UNIROC provides a concrete process mechanization solution that covers waterproof board reinforcement operations, fully computerized lining, and digital curing to address issues such as arch voids, concrete segregation, honeycomb and rough surfaces, uncontrollable processes, difficult data traceability, and inadequate curing in traditional secondary lining construction. UNIROC has independently developed and produced waterproof board trolleys, fully computerized lining trolleys, digital maintenance trolleys, hydraulic arch piers, hydraulic ditch cable trays, etc. to provide a small-scale assembly line for arch construction and meet the needs of one-time molding and rapid construction of tunnel arch concrete.
