    摘要： A method of cutting underwater structures which comprises the following steps:

    a local underwater step including:
    the anchorage of cutting means (T) in the cutting area, exactly positioned to effect the desired cut, to the structure (S) to be cut;
    a remotely-controlled step including:
    the automatic activation and de-activation, from a spot at the surface, of the cutting means (T) and the automatic feed thereof in the cutting direction from a non-interference position through the structure (S), the cutting means (T) being provided with cutting tools (14) for cutting metallic and non-metallic materials such as, for example, cement, concrete, rocks, or the like;
    a local underwater step for recovering the cutting means (T).
    The invention proposes as well a device for carrying out the method.

    摘要： The invention relates to an apparatus for working, especially cutting tubular and round-bar type pieces (1), said apparatus comprising a clamping mechanism (2) adapted to be fastened to said work piece (1) rotatably therearound and said clamping mechanism (2) having attached thereto a tool unit (3), which is provided with adjustment means (4) for displacing said tool unit (3) relative to the clamping mechanism (2) towards or away from the work piece (1), and said clamping mechanism (2) including a frame element (5) and first and second arms (6, 7) extending therefrom, said arms (6, 7) being articulated at one end to the frame element (5) of the clamping mechanism (2) and each arm (6, 7) has its free end fitted with a bearing axle (31, 32), which is provided with at least one bearing wheel (15, 16), the clamping mechanism (2) having its frame element (5) provided in a rotatable and axially immobile fashion with a threaded shaft (20), whose first end has a right-handed thread provided with a first nut (21) and whose second end has a left-handed thread provided with a second nut (22), and said threaded shaft (20) being provided with a member (23) for rotating the threaded shaft (20), and the first arm (6) and the first nut (21) being articulated to each other by means of a first suspension arm (24) and the second arm (7) and the second nut (22) being articulated to each other by means of a second suspension arm (25). The apparatus further comprises two second bearing axles (33, 34), fitted adjustably relative to their mutual distance between the arms (6, 7) and the frame element (5), each of said axles being provided with at least one bearing wheel (35, 36).
