The present invention relates to a method and device on suction dredgers, through which the dredged material that has deposited in the holds is sucked out of them again and then can be carried in barges to the bank or other places.

According to the invention, the suction of the deposited dredged material is through its liquid ^ - make it possible by adding enough pressure to the bottom of the water before vacuuming ίο Holds is pressed in. The liquid dredged material is then passed through a bottom in arranged in the loading space of the suction dredger, provided with closable openings Suction channel, which is connected to the suction pump of the excavator, off again vacuumed from the holds and transported further at will.

The device used for this purpose is shown in the accompanying drawing illustrates:

Fig. Ι a longitudinal section and

Fig. 2 shows a cross section through the loading space of a suction excavator, while
Fig. 3 is a view of the cargo space from above, but on a larger scale.

As usual, the suction dredger is arranged with a side or in another known manner Suction pipe 2 equipped with suction pump 3, which carries the dredged material either through pipes 4, 5 and 6 into the hold 7 of the Excavator or through the tubes 4 and 8 in barges or to the bank.

The loading space 7 is on both sides of the suction pipe 9 arranged on its floor provided with the usual bottom flaps 10, through which the cargo space can be opened in a known manner. Way can dump into the sea; the bottom flaps are secured by chains 11 and associated Winding devices 12 closed and open as usual.

The suction tube 9 can either be a single tube or, as shown in Fig. 2, be formed by a double channel 13. The double channel 13 is through at the front end the pipe socket 15 (FIG. 1) which can be closed by means of the slide 14 with the outside water in Connected, and the rear end is also closable by means of a slide 16 Pipe 17 connected to the suction pump.

The lower part of the hold 7 is divided into individual spaces by transverse bulkheads 18; each of these spaces is by means of two side openings which can be closed by slides 19 connected to the suction channel 13. All slides 14, 16 and 19 are operated from the deck emotional.

To make the deposited dredged material liquid, as already mentioned, Water at the bottom of the hold in the dredged material through special pipes 21 and 22 pressed in, which by means of a leading to each compartment of the hold and with a tap 23 provided pipe branch 24 open into these spaces. The final cocks 23 are also moved from the deck (Fig. 2).

(2nd edition, issued on January 10th igio.)

The pressurized water for the pipelines 2i and 22 is taken from a special pump 25 (Fig. Ι and 3).

When the excavator self-empties, proceed as follows:

After being opened by the pump 25 by means of the pressurized water lines 21 and 22 Final cocks 23 pressed water into the dredged material and made the dredged material liquid has been, after switching off the suction pipe 2, the closing slide 14 and 16 of the suction channel 13 opened and the suction pump started, whereupon water through the Suction channel 13 flows.

Then the slides 19 are opened as required to the liquid dredged material in admit sufficient quantities into the suction channel 13. The dredged material is then through the Suction channel 13 sucked off and conveyed further through the pipe 8, wherein the water slide 14 can be partially closed.

Of course, pressurized water can also flow through the during the evacuation Tubes 21 and 22 are pressed into the hold.

The division of the cargo space by the transverse bulkheads 18 facilitates its emptying, by closing the slide 19 as soon as the associated compartment has been emptied.

The method and the device can also be used for excavator frames, whose holds are set up in the manner described. Such a pram will placed next to a suction excavator and its pressure lines 21 and 22 and its suction channel 13 connected to the press pump 25 on board the excavator and to the suction pump 3, whereupon the dredged material can be made liquid in the prahm in the manner described and sucked off.

Claims (2)

Godfather NT-An Proverbs: ι. A method of emptying by suction dredgers and dredging barges using water streams, characterized in that the entire charge is before the start of the idle suction by injecting W ^T ater down into the cargo hold liquefied, whereupon this liquid dredged material passes into a bottom channel, from which it is sucked off by generating a water flow in a known manner by means of a sludge suction pump and conveyed further. ■. ■ ■ 2. To carry out the method characterized in claim ι the Arrangement of the pressurized water lines (21 and 22), the bottom in. Each of the through the Transverse bulkheads (18) formed parts of the hold (7) open into which likewise those arranged on both sides of the suction channel (13) by means of a slide (19) open out closable openings, as well as the arrangement of the closable Connection (15) of one end of the suction channel (13) with the Outside water and its other end by means of the pipe (17) with the sludge suction pump (3) such that after opening the slide (19) the liquefied Dredged material completely through the in the suction channel (13) by means of the sludge suction pump (3) generated water flow can be sucked through this channel. 1 sheet of drawings.
