Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a landfill device for spraying earth and sand transported from land or water on the surface of the water, and embanking the land for continuous landfill.

[0002]

2. Description of the Related Art A conventional landfill method is disclosed in Japanese Patent Laid-Open No. 48-10 / 1988.
As disclosed in Japanese Patent No. 1729, a series of devices including a floating belt conveyor is used, and landfilling is continuously performed from above the water, and as shown in Japanese Patent Publication No. 57-17811, it is placed on land. Some landfills are continuously landfilled from land, using a series of equipment such as self-propelled belt conveyors.

[0003]

The former landfill can be carried out continuously from the water because it is a floating type.

However, the work cannot be performed depending on the meteorological conditions of the landfill water area, and it is -3.
5 When landfilling from the surface of spraying rice to above the water surface, there was a problem that the carried-out earth and sand and crushed stones flowed at an angle of repose and covered the float of the floating sprayer, obstructing the movement of the float.

Further, the latter landfill can be continuously performed from the land, and the landfill work can be continued without being affected by the weather conditions of the landfill water area.

However, since the embankment point of earth and sand moves along with land reclamation from land, the sludge is contained evenly under the surface of the water as if land reclamation from above the water, and then the embankment is filled. The system could not be adopted, and there were problems such as pollution problems due to the movement of sludge and extremely soft ground (due to the uneven thickness of the sludge layer that moved) depending on the location.

For this reason, both landfill methods are used properly,
Alternatively, there are inconveniences that must be used together and economical inconveniences.

Therefore, an object of the present invention is to make it possible to perform landfill from above water and from land by means of a series of devices.

[0009]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a cargo receiving conveyor for receiving earth and sand or crushed stone carried by an appropriate method, and a plurality of intermediate transfer conveyors extending forward from the cargo receiving conveyor. , The tail and head of the tripper conveyor extending forward from this leading edge relay conveyor are connected horizontally so as to freely follow the position of the water surface and rolling, and at least the relay The floats that can be slid on land are used for the conveyor and tripper conveyor.

[0010]

Operation: The cargo receiving conveyor is supplied with earth and sand or crushed stone which is carried on land by a belt conveyor or the like, or carried on water by an earth carrier.

The earth and sand and crushed stones on the load receiving conveyor are transferred to the tripper conveyor through the intermediate transfer conveyor, and are sprayed from the tripper conveyor to the water surface to fill the earth.

The relay conveyor floating on the water via the float changes the spraying point of earth and sand and the embankment point while being moved by a tripper conveyor, a wire puller connected to each relay conveyor or a push boat.

From the water to the embankment, a tripper conveyor,
The tripper conveyor and the intermediate transfer conveyor are pulled up while sliding the float by pulling a wire connected to each intermediate transfer conveyor.

At this time, only some of the relay conveyors may be pulled up.

For land spraying, a cargo receiving conveyor, each relay conveyor, only a tripper conveyor, or a combination of a self-propelled tripper conveyor and a self-propelled spreader instead of the tripper conveyor, is used. The type tripper conveyor and the self-propelled spreader are self-propelled, and other than pushing the wire, they may be pushed by a bulldozer or the like.

[0016]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 4, in front of the cargo receiving conveyor A for receiving the carried earth and sand or crushed stone,
A plurality of relay conveyors B extending forward are arranged, and a tripper conveyor C is provided in front of the most advanced relay conveyor B.
And the head and tail of the receiving conveyor A and the relay conveyor B, the head and tail of each relay conveyor B, the head and tail of the most advanced relay conveyor B and the tripper conveyor C rotate in the horizontal direction, and It is connected via a connecting device 1 which can freely follow changes in the water surface and rolling.

Further, at least the relay conveyor B and the tripper conveyor C can be slid on land (on land, both ends in the front-back direction and the left side surface are arcuate surfaces so as to be sled). It is installed on the naval float 2.

When the head side of the cargo receiving conveyor A projects above the water surface, the float 2 is provided not only on the head side of the cargo receiving conveyor A but also on the tail side as well as on the land side. When moving or changing the direction of the cargo receiving conveyor A, for example, a bulldozer may be connected to the land via a wire, and the float 2 may be slid by towing.

The connecting device 1 described above is shown in FIGS.
As shown in FIG. 4, a circular base 4 is provided on a float 2 arranged at the transfer portion of earth and sand or crushed stones so as to be pivotable by a plurality of rollers 3 supporting the lower surface and the periphery, and the base 4
The hinge frame 5 is arranged on both sides of the upper side and is constituted by a hinge piece 5 protruding upward and a horizontal pin 8 rotatably connecting a hinge piece 7 protruding downward from the conveyor frame 6, and a divided frame 9 of the intermediate conveyor B. As shown in FIGS. 8 and 9, arrange the float 2 under the opposite end, and
The leg material 10 that stands up from the float 2 and the leg material 1
0 and the horizontal pin 12 that rotatably connects the left and right hinge pieces 11 that overlap the conveyor frame 9, but a connecting method that achieves the same purpose by the above structure may be adopted.

With the above-mentioned structure, the cargo receiving conveyor A is supplied with earth and sand or crushed stones which are carried on land by a belt conveyor or the like or on the water by an earth carrier.

The earth and sand and crushed stones on the receiving conveyor A are transferred to the tripper conveyor C through the intermediate transfer conveyor B,
The water is continuously sprayed from the tripper C ′ (shown in FIGS. 10 and 11) to the water surface.

The above spraying is changed by the movement of the tripper C'and the movement of the relay conveyor B and the tripper conveyor C by the pulling of the wire (not shown) connected to each float 2 or the like or the pushing ship (not shown). .

If the above-mentioned spraying is carried out substantially uniformly up to several rice on the surface of the water, the sludge can be stopped and sealed.
Eliminate the inconvenience that the soft ground is partially generated due to pollution problems and sludge movement.

After that, embankment is performed up to a height of several rice on the water surface.

Note that the land is continuously filled while being evenly dispersed so that arc slip does not occur concentratedly on the embankment.

When landfilling cannot be done from the water due to deterioration of weather conditions during landfilling, or when earth and sand or crushed stones are further dispersed on the ground after embankment, the intermediate conveyor B is drawn on the embankment by pulling the connected wire. And tripper conveyor C
While sliding the float 2, pull it up to the land as shown in FIG.

Then, spraying is carried out in the same manner as described above. At this time, the relay conveyor B and the tripper conveyor C are moved while sliding the float 2 by towing and pushers.

The self-propelled tripper conveyor C "may be used for soiling from the tripper conveyor C.

Further, since the spraying point can be changed by sliding the float 2, it can be used for landfill from land as shown in FIG.

[0031]

[Effect] Since the landfill device of the present invention is constructed as described above, it is possible to perform landfill from above water or from land.

For this reason, two types of landfilling from the water and landfill are not required, and if landfilling from the water is not possible due to weather conditions, it is possible to landfill, delay the construction period, or The uneconomical inconvenience can be eliminated.
