In this embodiment, the removal target that causes the pollution is removed by removing high-pressure water on the purification object 2 such as rocks and gravel scattered on the river bed and removing the removal object. It shows what was collected and collected at a certain location.
[0009]
Reference numeral 3 denotes a work vehicle (a work machine body that can be moved by itself). In this embodiment, the work vehicle is a truck crane equipped with a telescopic boom 4 that can be raised and lowered.
[0010]
The vehicle 3 includes a swivel base 5, and in addition to the engine, the swivel base 5 includes a suction pump 6, an air compressor 7, and a recovery pump 8, which are high-pressure water generation sources, as shown in FIG. 2. It is equipped and can be linked to the engine. A terminal pipe 10 is connected to the recovery pump 8 so that the recovered product is drained into a recovery container 13 with a porous drainage 12 mounted on a chassis 11.

Reference numeral 15 denotes a high-pressure water (and pressure air) induction hose. The hose 15 is flexible and is provided along the boom 4 so that it can be expanded and contracted. The hose 15 is suspended through a guide sheave 16 provided at the tip of the boom 4 and has an injection pipe 17 at the lower end thereof. The induction hose 15 or the injection pipe 17 may be provided with a balancer for maintaining a vertical state and stabilizing high-pressure water injection. This balancer may be a tripod-like one arranged on the outer periphery of the injection pipe 17. The injection pipe 17 itself may be heavy and a balancer.
Although the high pressure water (and air) injection method is used in the above-described embodiment, a method in which only pressurized air is injected may be used.
[0012]
As shown in FIG. 1, a stay 19 projects from the tip of the boom 4. One end of the stay 19 is connected to the collection pump 8 and is provided along the boom 4 so as to be stretchable and flexible. A hose 20 is attached, and the hose 20 is suspended from the stay 19 and includes a recovery pipe 21 with a nozzle 18 at the lower end thereof.
[0013]
A recovery bucket 22 is attached to the lower end of the recovery pipe 21 in a continuous manner. One end opening 22a of the bucket 22 is on the downstream side of the injection pipe 17 and is directed toward the opening 22a. In addition, as shown in FIG. 2, the recovery pipe 21 and the injection pipe 17 may be integrated with a connecting member 23.
[0014]
The work vehicle 3 is parked in a stable posture with an oblique outrigger in a gravel land of the river 1 or an appropriate place outside the river 1. Then, the boom 4 that has been reduced so far is extended, the high-pressure water induction hose 15 and the recovery hose 20 that have been entrained are extended, and the injection pipe 17 and the recovery bucket 22 are submerged in the river 1. Both hoses 15 and 20 are suspended.
[0015]
In the state shown in FIG. 2, the suction pump 6 and the recovery pump 8 may be driven by the engine operation, and the air compressor 7 may be driven simultaneously.
Thereby, high pressure water is jetted from the nozzle 18 and sprayed onto the purification object 2... And the removal object adhering thereto is sucked into the bucket 22 through the opening 22 a on the downstream side, and passes through the recovery hose 20. It is collected in the collection container 13. Since the collection container 13 is provided with the porous drainage section 12, only the removal target that has been drained and dehydrated is accumulated.
[0016]
The positions and heights of the nozzle 18 and the bucket 22 on the plane are determined by turning the boom 4, raising / lowering, extending / contracting, and hoist hoisting / feeding means (not shown).
Instead of the bucket-type recovery means, as indicated by a phantom line in FIG. 2, recovery may be performed by a donut-shaped recovery means 24 provided on the outer periphery of the nozzle 18.
[0017]
In addition, although it is another system, the purification target object may also be collected and stirred at the collection destination to remove the removal target object and return only the purification target object.
In this case, only a part of the purification object may be returned to the original, and the remaining part may be mixed as a purification promoting material such as new barley stone.
Further, as indicated by the phantom line 22 in FIG. 2, after the purification object is sucked in and rotationally stirred to remove the removal object, only the removal object may be diffused and discharged to the floor as it is.
[0018]

On the other hand, the stern side b is also equipped with a rear guide roller 46 via a rear parallel link mechanism 45, and a recovery bucket 49 connected to a recovery pipe 48 including an expansion / contraction part 47 is attached to the link mechanism 45. Note that, as indicated by a virtual line in FIG. 6, the high-pressure water pipe 43 may be brought close to the recovery bucket 49. Conversely, the bucket 49 may be moved closer to the high-pressure water pipe 43 side. Moreover, you may arrange | position both the high pressure water piping 43 and the bucket 49 corresponding to a ship's bottom. In such a case, the number of link mechanisms is reduced to one, and the entire apparatus is simplified.
[0021]
The discharge ports of the high-pressure water pipe 43 and the bucket 49 are always controlled at a certain close height from the object to be purified 2 by the guide rollers 42 and 46 as gauge means. Then, by driving the high-pressure water pump 37 and the recovery pump 50, high-pressure water is jetted from the high-pressure water pipe 37 toward the purification target object 2 to remove the removal object, and the removal object is downstream. It is sucked into the bucket 49 and collected in the collection tank 38 via the collection pipe 48. Only the object to be removed is removed in the tank 38 and the water is led into the return tank 40 and used as high-pressure water.
[0022]
7 and 8, the driving means 53 that can be vertically moved on both sides of the hull (self-movable work machine body) 52 , can be rotated in the forward and reverse directions, and can control the rotational speed of the left and right is a chain.

The high-pressure water from the high-pressure water pump 61 is supplied from the high-pressure water pipe 57 through the pipe c in FIG. . . The high pressure water is jetted from the tip of the claw 55 and the like. Then, the removal object and water by the injection are guided into the bucket 63 provided on the downstream side of the claw 55 via the recovery pipe 62 and are recovered in the recovery tank 58 through the pipe d. The claw 55 also needs a gauge ring, and the claw 55 is forced upward and downward by the lifting means 64 so as to be naturally moved up and down. It should be noted that the drive object 53 may be agitated and the removal object and water may be recovered through a duct on the outer periphery thereof. This can be configured by itself.
[0023]
In the embodiment of FIG. 9, not only the removal target object is recovered by jetting high-pressure water, but also a part of the purification object 2... ... is dropped and mixed with the existing one.
That is, reference numeral 66 denotes a hull. The hull 66 is provided with a collecting tank 67, a return tank 68, a recovery pump 69, and a high-pressure water pump 70. A parallel link mechanism 71 is provided on the bow side of the hull 66, and the mechanism 71 is equipped with a collection body 73 having a gauge wheel 72. The recovery body 73 is a top-closed container with a hole 74 in the bottom surface, and a donut-shaped recovery inner ring 75 is formed on the outer periphery thereof.
