Swedish manufacturer Conjet AB's latest machine to join its range
of high pressure water jetting equipment is the compact Conjet
Robot 302.
The hydrodemolition unit, which selectively removes weakened and damaged steel-reinforced concrete from a broad range of structures, is primarily used to repair small concrete tunnels. Tunnels as small as 1.5m in diameter can be tackled.
The remotely controlled tracked robot, which can adjust its tracks to suit the shape of the tunnel invert, carries a special hydraulically driven rotor complete with two or four high-pressure water jetting nozzles.
The rotor is mounted on a rotating and telescoping boom which allows the cutter head to constantly follow the tunnel wall profile and maintain the nozzles' preset angle of attack on the concrete. Maximum concrete removal depth with the rotor cutter is 50mm.
The computer controlled machine can be armed with a range of software programs to ensure that concrete is selectively removed in a continuous, uniform and safe way.
