A suction dredger, floating body of which contains tightly interconnected main pontoons, as well as at least one additional pontoon, in the cavity of the main pontoon there is a soil pump, drive motor. The soil pump is connected with a pressure and suction pipes, the suction pipe is mounted with a possibility of vertical movement relatively to the pontoons by means of lifting mechanism located at the forebody of the floating body and comprises two starting and end ports of rigid pipe interconnected by a flexible hose, has a work motion mechanism containing rope winches with a drive, and at least one transversal platform interconnecting pontoons. Floating body is made of at least three rigidly interconnected with spaces main pontoons. The after-pontoon is equipped with soil pump and stuffing box flushing pump and pump of hydraulic washing-out of high pressure with drive motors. At the input there is a protective grating. Forebody pontoons are located along the hull of the floating body symmetrically to diametral plane parallel to longitudinally space relative to each other and interconnected at the forebody by cross beams of connecting platform with athe lifting mechanism of the starting part of the suction pipe. After-end of each forebody pontoon is connected to the forebody pontoonby by means of truss frame structure. At least two additional pontoons are removably fixed along forebody pontoons and truss frame structure on the sides. |
