Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to reclamation equipment used for reclamation of marine areas and the like.

BACKGROUND OF THE INVENTION In the past, earth lifting vessels used for reclaiming land on the sea, etc., were of the gutsu lifting type and the monotori claimer type.

Problems to be Solved by the Invention However, although the grab-and-lift method can effectively unload soil with small and uniform particle sizes, such as those on mountains,
When the grain size of rocks becomes large, a grab that lacks the ability to crush rocks at the stage of gripping the rocks cannot completely close the system, and dirt falls from the entrance of the grab.

Therefore, there was a problem that it was not suitable for transporting earth and sand containing rocks.

On the other hand, the reclaimer type is a method in which a metal packet is attached to the circumference of the rotating body, and as the packet rotates, it moves horizontally by a certain distance to scrape dirt into the packet. If a small number of large rocks are present, the rocks may get caught in the teeth of the packet, making it difficult for them to enter the packet, which reduces efficiency, making it unsuitable for transporting large rocks. Ta.

By the way, it is conceivable to crush the rocks contained in the earth and sand to a size of about 150" that can be easily transported, but crushing the rocks takes time and effort, and significantly increases the price of the earth and sand. This will cause a separate problem.

An object of the present invention is to provide a landfill facility that can solve such problems.

Means for Solving the Problems In order to solve the above-mentioned problems, the reclamation equipment of the present invention includes a lifting barge equipped with a belt conveyor for lifting soil extending from the bottom of the ship upwards outside the ship, and a barge that rotates on a vertical axis. The structure includes a revolving boom, and an earth lifting terminal in which the revolving boom is provided with a dropping belt conveyor for transporting earth and sand supplied from the belt conveyor of the earth lifting barge.

In other words, with this configuration, the earth lifting barge loaded with earth and sand is directed to the earth lifting terminal installed at a predetermined location, berthed, and moored. Then, the earth and sand is supplied onto the earth lifting terminal by the earth lifting belt conveyor, and the earth and sand is dropped onto the required location on the water by the dropping belt conveyor provided on the revolving boom of the earth lifting terminal. Since the transport of the earth and sand is carried out by belt conveyors in both the earth lifting barge and the earth lifting terminal, there is no problem even if the earth and sand contains large rocks.

Example Hereinafter, one embodiment of the present invention will be described based on the drawings.

In Figures 1 to 4, (1) is the landfill equipment according to the present invention, which is mainly comprised of a lifting barge (2) and a lifting terminal (3).
). The soil lifting barge (2) is equipped with a belt conveyor (4) for lifting soil extending from the bottom of the ship to the upper part of the bow along the bow and stern direction, and a gate is installed at the lower end on the belt conveyor (4) for lifting soil at the bottom of the ship. (5) is provided with a hopper (6) for loading earth and sand. A plurality of gates (5) of the earth and sand loading hopper (6) are installed at predetermined intervals along the bow and aft direction. Therefore, any gate (
5) is automatically opened and closed to dump the earth and sand in the hopper (6) onto the soil lifting belt conveyor (4), and this earth and sand will be carried to the upper part of the bow by the soil lifting belt conveyor (4). By selecting the gate (5) and the gate (5), the parast adjustment of the earth-lifting barge (2) will be performed. (7) is installed at the stern end of the earth-lifting barge (2) and is the next entry part, and a pusher (8) is installed in this recessed part (7).
The bow of the ship is fitted.

The soil unloading terminal (3) Fi is constructed in a crescent shape in plan view with a rock wall for docking the soil unloading barge (2), and a swing boom (9) that rotates around a vertical axis is located on the bottom deck of the soil lifting terminal (3). It is provided. As is clear from FIG. 1, this swing boom (9) is retractable along the long side of the earth lifting terminal (3). αQ is a dropping belt conveyor installed along the swing boom (9), αυ is a pedestal that supports the swiveling boom (9), and (2) is an earth and sand receiver installed to pass under this mount αυ. It is a conveyor belt conveyor, one end is below the first hopper ■ installed corresponding to the belt conveyor (4) for lifting soil of the soil lifting barge (2), and the other end is above the base end of the belt conveyor α0 for dropping soil. They are respectively positioned above the installed wc2 hopper 04. Therefore, the soil dropped from the soil lifting belt conveyor (4) is transferred from the first hopper Q3 to the receiving belt conveyor (6). It is guided to the second hopper α, and from the second hopper α, it is guided to the dropping heald conveyor OG.
9αQ is the control room and generator room that perform these controls,
Each is provided on the short side of the soil lifting terminal (3). αηQS is the living area and edge deck installed at the end of the long side of the earth lifting terminal (3), and Q SAMURAI is the large and small winch installed at each corner of the earth lifting terminal (3), and the anchor wire is mooring lines (goods), or mooring ropes (goods) let out from the unloading barge (2).
It functions as the volume JIX, etc.

With such a configuration, the procedure for carrying out offshore reclamation work using the present reclamation equipment (1) will be explained based on FIGS. 5 and 6.

First, the unloading barge (2) loaded with earth and sand (including rocks) at the loading base □□□ is pushed by the pusher (8) to the unloading terminal (3).

At the earth-lifting terminal (3), the earth-lifting barge (2) which has previously lifted the soil is berthed by a tugboat (1), and the earth-lifting barge (2) loaded with the earth and sand is berthed.

After berthing, the pusher (8) is released from the unloading barge (2) and the empty unloading barge (2) held by the tugboat (E) is released.
) and direct it to the loading base (7).

At the soil lifting terminal (3), after mooring the soil lifting barge (2) and connecting the power supply, the belt conveyor for soil lifting (4) - 1st hot) <-03-'f2ffffL belt conveyor (2)
- Second hopper (b) - Unloading soil in the order of belt conveyor QQ. In this case, the swing boom (9) is swung to a predetermined position. In Figure 5, (Foundation) indicates existing reclaimed land, (E) indicates new reclaimed land, 翰 indicates Nameshi stable land, and (7) indicates planned landfill site.

Then, the earth lifting terminal (3) is gradually moved between these f'F and Qinzhong, and this is done by operating the winch a9. The anchor (1) itself is relocated by an anchor barge.

By the way, if the earth-lifting barge (2) is of the hopper gate type as in this embodiment, it is possible to unload cargo with a large capacity of 10,000 t/h, which is higher than the current maximum capacity of 2,000 t/h (normally used). 1,500t/h), which is significantly higher (approximately 5 times).

Therefore, if the reclamation work is carried out in the same work period as in the conventional plan, only 115 soil lifting barges (2) will be used, which can alleviate the traffic rush in the narrow reclamation area.

In addition to the effects of the invention, according to the present invention, even if large grain size rocks are included in the earth and sand used for reclamation, it can be transported without any problems,
Moreover, it is possible to obtain more landfill capacity than before.
