    Patent number: 10981202
    Abstract: An apparatus for hydrodemolishing the inside surfaces of an inclined pipe, particularly suited to contiguous pipe sections with access ports between the sections. The fluid supply hose is fed to the hydrodemolition rig inside the pipe from the same side as the winch that controls the movement of the rig. The rig is moved upstream in a scarifying pass, then downstream in a cleaning pass for each section and re-staged at each access port.
