Method for hydraulic ceiling-concrete removal |
摘要 |
An apparatus and method for removing concrete from a ceiling surface by hydrodemolition which includes a mobile truck unit adapted for movement along a floor surface or the like and which supports a pair of upstanding telescoping support arms having an elongated boom mounted at their upper ends in a manner to enable selective orientation of the boom relative to a ceiling surface. A carriage is mounted for reciprocating movement along the boom and carries and upwardly directed lance and discharge nozzle operative to discharge high pressure fluid, such as water, against a ceiling surface such that selective movement of the nozzle and mobile truck during high pressure fluid discharge are operative to remove concrete from the ceiling surface.
