Description

Description: TECHNICAL FIELD The present invention relates to a waste treatment structure having an outer shell made of a floating structure having a box-shaped barge structure, which is used as an intermediate treatment facility for wastes called separation waste. .

[Problems to be Solved by the Invention]

Conventionally, the waste called separated trash is not disposed of by incineration but reduced by intermediate treatment and then disposed of at the final treatment plant. However, the amount of general waste generated in cities and the like has increased rapidly in recent years, and the problem of rubber processing has become more serious.

Given the land and environmental problems that cities currently have, it is extremely difficult to incinerate waste and construct a new intermediate treatment facility for crushing and reducing the volume inland. For this reason, at present, a method of landfilling waste as it is at a final disposal site located near the coast is used, but this method is not a preferable method and a drastic solution has been required.

The present invention has been made in view of the above problems. The purpose is to propose a structure for the treatment of separated waste waste that does not require inland land, does not affect neighboring residents, can be moved and converted, and can reduce damage even against earthquakes. There is.

[Means for Solving the Problem] This waste treatment structure is a ballast water control means for moving the shell by forming a floating structure with a concrete outer shell, operating by landing on the bottom of the water, and re-floating. And a waste crushing device, and a sliding seismic isolation mechanism is configured between the bottom surface of the outer shell and the foundation bottom slab provided below the outer shell.

〔Example〕

Hereinafter, description will be made with reference to the illustrated embodiment. The drawing shows the waste treatment structure 3 fixed and installed on the seabed 2 of the shallow sea area 1 of the inland sea. The outer shell 4 of this structure has a box-shaped barge structure. The bottom and sides of the outer shell 4 are occupied by a ballast water tank 5 partitioned into a number of spaces, and a base bottom slab 6 is attached to the bottom surface of the bottom.

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

There is a crane 11 in the upper part of the garbage pit 8 and a garbage crushing section 9
The hopper 12 that communicates with is opened. The dust crushing unit 9 is provided with a dust crushing device including a dust crushing machine 13, a dust sorting machine 14, and a dust volume reducing device 15.

The outer shell 4 of this structure is made of concrete such as precast concrete or reinforced concrete, the inside has a height of four floors, and the roof 16 has a reinforced structure.
Further, although not shown, a water pump is provided so that the ballast water can be adjusted to be submerged and re-floated freely. By finely adjusting the ballast water, the balance of the outer shell 4 and the ground pressure can be adjusted to allow soft landing. .

The base bottom slab 6 is towed and sunk together with the outer shell 4, but it works as a structure having a sliding seismic isolation mechanism with the bottom surface of the outer shell 4 after it touches the seabed ground such as soft ground.

[Work]

This waste treatment structure has the above structure. The outer shell of this structure has a floating structure and has means for adjusting the amount of ballast water, so after construction, towing to the desired sea area,
Ballast water can be injected to operate as a facility for bottom treatment, installation, and intermediate treatment of waste with a crushing function. In addition, the ballast water can be discharged, re-floated, moved to the installation position, or disassembled and removed at the destination. The position of the center of gravity can be freely controlled by adjusting the ballast water as necessary, such as during towing, subsidence, or tide level fluctuation during operation.

To dispose of waste with this structure, as shown in the drawing, the trash or trash container 18 transported by sea from a small ship or trash container ship 18 is unloaded onto the terminal with the gantry crane 10 and then the trash pit 8 or the trash container. Brought to pit 7. The separated trash carried in is sent from the homper 12 to the crushing section 9, where it is crushed, sorted and reduced in volume, and then transported to the final disposal site for disposal.

Normally, trash or trash containers are transported by land to the final disposal site by truck, and then over piers, etc., to a processing structure installed in the nearby sea area, where crushed and volume-reduced trash is collected on the course. In reverse, carry it to the final disposal site for disposal.

〔The invention's effect〕

 This waste treatment structure has the following effects.

An intermediate treatment facility can be easily constructed without being bound by land and environmental problems.

It can be repeatedly towed, sunk, and operated to operate in any sea area. When it is no longer needed, it can be dismantled and removed at the site or at a location other than the site.

 Since it can be built in the dock, the construction period can be shortened.

Since it can be installed on a soft bottom, it does not sway compared to a floating structure and can be operated even in windstorms, and since the ground contact pressure is small, the structure will slide during a large earthquake and large inertial force can be avoided.

Furthermore, the foundation slab is provided under the bottom of the outer shell to form a double-structure sliding seismic isolation mechanism, so that in the event of a large earthquake, the inertial force can be suppressed below a certain value and large damage can be prevented.

Since it can be installed in the sea area near the final disposal site, it mainly contributes to sea transportation, reduces land transportation, and contributes to alleviation of road traffic congestion. At the same time, transportation of the residue after intermediate treatment to the final disposal site becomes very easy.

Since the balance and ground pressure of the structure can be adjusted with ballast water for soft bottoming, there is no need for large-scale foundation work for the bottoming ground.

Since the outer shell is made of concrete such as precast concrete or reinforced concrete, it does not rust even in the sea and can be used for a long time.

In addition to the garbage disposal function for the structure, as an incidental facility,
Public facilities such as fish farms, aquariums, tennis courts, saltwater pools, parking lots, etc. can also be provided, which can be highly utilized as leisure facilities on the waterfront.
