The floating body 3 is connected to a boat (not shown) via a connecting rod 7 that engages with a U-shaped metal fitting 6 projecting from the bow of the floating body 3 and towed by the boat. It should be noted that the floating body 3 may be made to fly by itself.

The mud tank 5 is divided into a primary tank 5a and a secondary tank 5b by a cylindrical inner wall 8a and an outer wall 8b that are concentrically provided in the center of the floating body 3, and both tanks 5a are separated. , 5b are connected to each other by a through hole 9 penetrating the inner wall 8a.

In the submersible pump 4, an opening 10 a of a suction pipe 10 connected to a suction port of the submersible pump 4 is inserted into a guide groove 1, and a scraper 11 made of hard rubber or the like is fixed to a bottom plate of the opening 10 a. Has its tip abutted against the bottom surface of the guide groove 1, and the opening 12a of the substantially L-shaped discharge pipe 12 connected to the discharge port of the suction pipe 10 communicates with the inside of the primary tank 5a. The precipitate 13 in the guide groove 1 is pumped up into the primary tank 5a via the suction pipe 10 and the discharge pipe 12. Further, the electric power required to drive the submersible pump 4 may be supplied from the boat side via a cable (not shown), or a battery may be provided in the floating body 3 to supply electric power. In the secondary tank 5b, sediment 13 such as earth and sand having a large specific gravity and muddy water 14 having a small specific gravity are vertically separated.

As shown in FIGS. 2 and 3, between the outflow port 15 formed at the upper end of the outer wall 8 b of the mud tank 5 and the discharge port 16 formed below the draft of the port side outer plate 3 a of the floating body 3. A pair of drainage channels 17 are formed obliquely downward in the bottom, and a filter 19 is fitted in a recess 18 formed on the side surface of the drainage channel 17 penetrating the deck 3b of the floating body 3 so that the filter 19 can be pulled out. The muddy water 14 overflowing from 5b to the drainage channel 17 is filtered by the filter 19 and returned to the water surface.

As shown in FIGS. 4 and 5, the guide member 2 includes a guide rod 20 fixed to a bottom plate of the floating body 3, an upper support plate 21 fixed to a lower portion of the guide rod 20, and a lower end of the guide rod 20. Lower support plate 22 bolted to the upper and lower parts, and a rubber tire 27 with a support wheel 26 rotatably fitted between upper and lower support plates 21, 22 via a bearing fitting 23, an oilless bearing 24 and an oilless washer 25.
