Abstract

PURPOSE:To obtain an intermediate disposal place easily without constraint by the site selecting and environmental problems by a method wherein an outer hull is formed of a floating structure and provided with a ballast water adjusting means which can be sunk to the sea bottom and floated on the surface and a waste crushing device and a cycle of towing, sinking and operation is repeated. CONSTITUTION:The outer hull 4 made of concrete or steel is of box-like, floating purge structure and capable of being freely floated on the surface or sink by regulating the amt. of ballast water and, by a fine adjustment of the ballast water, the balance of the outer hull 4 can be retained and a hull-to-ground contact pressure can be adjusted. A foundation bottom plate 6 is towed and sunk integrally with the outer hull 4 and, after contact with the sea ground such as a soft ground, it functions as the structure having a slidable earthquake-proof mechanism between the bottom surface of the outer hull 4 and the sea ground. The dirt or container 18 transported by a boat or container ship 17 is unloaded onto a terminal by a gantry crane 10 and carried into a dirt pit 8 or container pit 17. Such dirt or container is sent from a hopper 12 to a dirt crushing part 9 to be crushed, sorted and reduced in volume, after which it is transferred to a final disposal place for treatment thereof.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a waste treatment structure consisting of a floating structure whose outer shell is a box-shaped barge structure, which is used as an intermediate treatment facility for waste called separated garbage.

[Problem to be solved by the invention]

Conventionally, waste, known as separated garbage, is not incinerated, but is reduced in volume through intermediate treatment and then dumped at a final treatment plant.

However, the amount of general waste generated in cities has increased rapidly in recent years, and the problem of garbage disposal has become more serious.

Given the land and environmental problems that cities are currently facing, it is extremely difficult to construct new intermediate treatment facilities for incinerating waste or crushing and reducing the volume of waste in inland areas of cities. For this reason, the current method is to simply dispose of waste in a final disposal site near the coast, but this method is not the preferred method, and a drastic solution is needed.

This invention has been made in view of the above-mentioned problems. The purpose is to propose a structure for the disposal of separated garbage that does not require inland land, does not affect neighboring residents, and can be moved and repurposed.

[Means to solve the problem]

This waste treatment structure is characterized in that the shell has a floating structure and is equipped with a ballast water regulating means for landing on the bottom of the water and making it float, and a waste crushing device.

〔Example〕

The following will explain the embodiments shown in the drawings. The drawing shows a waste treatment structure 3 that is anchored and installed on the seabed 2 in a shallow area 1 of an inland sea. This structure has a floating body structure in which the outer shell 4 is a box-shaped barge structure.

The bottom and sides of the outer shell 4 are occupied by a ballast water tank 5 divided into many spaces, and a foundation bottom plate 6 is provided on the lower surface of the bottom.
is the installation.

Inside the outer shell 4 are a garbage container pit 7, a garbage pit 8,
It is divided into a trash crushing section 9. A gantry crane 10 is installed on the terminal above the garbage container pit 7.

There is a crane 11 in the upper part of the garbage bit 8, and a hopper 12 communicating with the garbage crushing section 9 is opened. The garbage crushing section 9 includes a garbage crusher 13. Garbage sorter14. A trash crushing device consisting of a trash volume reduction device 15 is provided.

The outer shell 4 of this structure is concrete) (PC.

It is made of RC structure (RC structure) or steel, the interior is four stories high, and the roof 16 is a steel structure.

In addition, although not shown, a water pump is provided to adjust the ballast water to float and sink freely, and the balance of the outer shell 4 and the ground pressure can be adjusted by finely adjusting the ballast water.

The foundation bottom slab 6 is integrated with the outer shell 4 and is towed and submerged, but after touching down on the undersea ground such as soft ground, it functions as a structure with a sliding seismic isolation mechanism between it and the bottom of the outer shell 4.

[For production]

This waste disposal structure has the above structure. The outer shell of this structure has a floating structure and has a means to adjust the amount of ballast water, so after construction, it can be towed to the desired sea area,
It can be operated as an intermediate waste treatment facility with ballast water injection, landing, installation, and garbage crushing functions. In addition, the ballast water can be discharged and resurfaced, and the installation can be relocated or disassembled and removed at the new location. The position of the center of gravity can also be freely controlled by adjusting the ballast water according to special needs such as tidal level fluctuations during towing, submersion, or operation.

To process waste in this structure, as shown in the drawing, garbage or a garbage container 18 transported by sea by a small boat or garbage container ship 17 is unloaded onto the terminal by a gantry crane 10, and a garbage pit 8 or a garbage container is loaded onto the terminal. It is brought to pit 7. The carried separated garbage is sent from the hopper 12 to the garbage crushing section 9, where it is crushed 1
After being sorted and reduced in volume, it is transported to a final disposal site for disposal.

Normally, garbage or garbage containers are transported overland by truck to a final disposal site, and then transported across a pier or the like to a treatment structure installed in the nearby sea area, where the crushed and reduced volume garbage is transported along its route. Follow the steps in the opposite direction and transport to the final disposal site for disposal.

〔Effect of the invention〕

This waste treatment structure has the following effects.

■ Intermediate treatment facilities can be easily constructed without being restricted by land or environmental issues.

■ It can be repeatedly towed, submerged, and operated in any sea area, and when it is no longer needed, it can be dismantled and removed on-site or moved off-site.

■ Construction time can be shortened as construction can be done inside the dock.

■ Because it can be installed with a soft bottom, there is no shaking compared to floating structures, and it can be operated even in strong winds.The ground pressure is low, so the structure can avoid sliding and large inertial forces in the event of a major earthquake.

■ Since it can be installed in the sea near the final disposal site, it can contribute to alleviating road traffic congestion by relying primarily on sea transport and reducing land transport. At the same time, it becomes very easy to transport the residue after intermediate treatment to the final disposal site.

■ The balance and ground pressure of the structure can be adjusted using ballast water, eliminating the need for large-scale foundation work on the ground.

In addition, if the foundation bottom slab is made into a double structure and a sliding seismic isolation mechanism is used as in the embodiment, in the event of a major earthquake, the inertial force can be suppressed to a certain value or less, and major damage can be prevented, which is preferable for the -layer. In addition to the garbage disposal function, the structure also has ancillary facilities such as fish farms, aquariums, tennis courts, seawater pools, etc.
It is also possible to provide public facilities such as a parking lot, making it possible to utilize the waterfront as a leisure facility.
