摘要:
In accordance with the invention, there is provided a concrete removing apparatus for removing concrete from an inclined wall of concrete having a frame with a front region. The frame may be supported on either a platform or from the wall with the front region adjacent to the wall. A carriage assembly is coupled to the frame assembly proximate a front region thereof, the carriage assembly extending from one side of the frame to another. A nozzle assembly is mounted on the carriage assembly and operative to move laterally of the frame assembly in response to activation of the carriage assembly. A nozzle on the nozzle assembly is operative to emit a jet of fluid against the wall of sufficient velocity to remove concrete from the wall. A transporting assembly is coupled to and operative to raise and lower the carriage assembly.

A method for, in particular completely or partially, disassembling a tower of a wind power plant, comprising the following steps: selecting suitable disassembly measures as a function of the tower location and the tower characteristics; preparing the disassembly, in particular of the tower and optionally the surroundings; carrying out the disassembly; and transporting the disassembled tower away.

A steeply inclined surface is hydrodemolished by providing a staging platform and a rig that includes a base frame defining a planar footprint within the frame. The rig is suspended from the platform by a cable such that frame is coplanar with the surface and the incline of the surface causes the rig to lean against it. Rails are provided on the surface to restrain spurious lateral movement of the rig. The rig is positioned on the surface and nozzles mounted on a trolley within a travelling carriage on the frame travel in two dimensions to hydrodemolish the surface within the footprint. The rig is moved vertically along the rails and laterally along the platform to reposition the rig to work a new section of the surface in conjunction with other rails that are also mounted on the surface.

A mobile vehicle mounted hydro demolition system comprising ultra-high pressurized water through a rotating nozzle water jet for cutting concrete, including a water supply, a vacuum blower, and a vacuum container that has offset with a dewatering bag so that incoming water can be pumped off as wastewater. A remote control gives an operator immediate adjustments of the rotational speed of the nozzle; the transverse traversing speed of the nozzle; the forward advancement of the vehicle; the number of traverses the head traverses before the vehicle advances its predetermined step; the pressure of the high-pressure pump; the amount of vacuum cfm's the blowers are producing; the steering of the vehicle; and the traversing distance of the rotating nozzle. By manipulating the above parameters the depth of removal is predictable and provides a consistent depth.

A device for the treatment of a surface, such as a flat and/or curved surface, the device including at least one surface treatment tool mounted onto a secondary motorized carriage capable of moving along a rail between two primary carriages that can move along tubes, preferably parallel, straight or curved. The primary carriages are mounted onto the rail, on the one hand, in such a way as to rotate around an axle that is orthogonal to the rail and, on the other hand, in such a way as to slide along the rail.

A boom is made of telescoping boom sections. A movable cutting nozzle is on the boom and sprays water. In one embodiment, the boom is coupled to the climber section of a platform that climbs a tower. A further beam is mounted on the other side of the hydraulic elevating platform and carries a movable power pack/counterweight. In a second embodiment of the present invention, the device is oriented horizontally and the platform moves horizontally on a rail. In this configuration, the elongated boom has a distal end protruding over the top edge of a dam or other structure. Depending vertically from the boom is another vertical boom carrying the cutting nozzle. This boom travels on the outer boom section of the elongated boom and extends downwardly a distance to allow the device to treat the concrete surface downward from the top edge of the structure.

A machine and method are disclosed for deconstructing walls and other substantially vertical surfaces. The machine comprises a static, stand-alone support-frame. A carriage is movably mounted on the support-frame, which carriage is operable to be raised and lowered along the support-frame adjacent to a workface. To the carriage are mounted one or more nozzles, preferably the nozzles are mounted to the carriage by means of a nozzle carrier that is operable to move back and forth along the length of the carriage. The nozzles are connected to a high-pressure supply of an erosive material, preferably water. The erosive material, when forced through the nozzles, form jet streams that are directed against the surface of the workface, thereby eroding the surface.Optionally, the invention comprises means of yawing or means of rotating the nozzles in order to access the sidewalls of the opening in the workface produced by the invention.Optionally, the invention comprises means of adjusting the nozzles towards or away from the workface surface in order to maintain an optimal gap between the nozzle and the workface surface as the opening gets deeper.Optionally, the invention comprises a work platform mounted on the support-frame and operable to be raised and lowered along the support-frame, thereby providing access to the workface for workers cutting rebar and carrying out other ancillary tasks.
