Description

[Detailed Description of the Invention] [Industrial Application Field] This invention involves constructing a caisson-type floating structure equipped with a waste crushing facility in a dock, injecting ballast, etc. after being towed, and sinking the structure. This relates to a marine structure that is installed with a relatively low ground pressure and used as an intermediate treatment facility for general waste.

[Prior Art and Problems to be Solved by the Invention] In recent years, the amount of general waste generated in cities has been rapidly increasing, and the problem of garbage disposal has become increasingly serious. Conventionally, intermediate processing facilities for crushing and processing this waste have been built on land, and intermediate processing of bulky waste generated in each prefecture, town, and village is performed at land-based facilities.

However, with the current rapid increase in general waste, it has become extremely difficult to construct new intermediate treatment facilities in inland areas of cities due to land and environmental problems that cities face. Therefore, the current method is to dispose of garbage in a final disposal site located in the sea, but constructing a new final disposal site is not a preferable method.

For these reasons, it is desired to come up with a drastic solution as soon as possible when constructing intermediate treatment facilities.

In order to solve these problems, it is conceivable to construct an intermediate treatment facility on the sea using a caisson-type floating structure or the like. However, conventional caissons are mostly used as the foundations of structures; they are manufactured in docks, towed to the destination, then sunk and fixed to the seabed, and used as the foundations of structures on top. It is.

Furthermore, since this conventional caisson is symmetrical in shape, it can be manufactured not only in docks but also offshore, and is easy to fabricate during towing and submersion. However, when an intermediate treatment facility is mounted on this caisson-type floating structure, the center of gravity of the structure does not necessarily coincide with the center of the caisson due to the asymmetric structure of the intermediate treatment facility. When the caisson is towed and sunk, it becomes unbalanced. Therefore, the above-mentioned advantages conventionally possessed by caissons are eliminated.

This invention was devised in view of the above-mentioned circumstances, and its purpose is to make it possible to efficiently crush and dispose of garbage at sea, and to use it to dispose of general waste at sea without causing land problems or environmental problems. The purpose is to provide a structure.

[Means to solve the problem]

In order to solve the above-mentioned issues, land issues, and environmental problems, a soft-bottom, offshore-based general waste crushing facility will be built in the ocean area of the final disposal site.

It can be considered as an effective means to make it operational.

Therefore, the marine structure for general waste disposal according to the present invention consists of a caisson body having a plurality of ballast parts, and a general waste crushing facility provided integrally with the caisson body.

The general waste crushing facility is also equipped with a trash pit, a crushing device, a sorter, and an iron recovery device.

In the marine structure for general waste disposal of this invention, the inclination of the caisson body can be freely changed by appropriately adjusting the plurality of ballast parts provided inside the caisson body, and the caisson body can be horizontally adjusted. In addition to maintaining
At the same time, it is possible to easily maintain the ground pressure of the caisson body to the seabed ground at a predetermined level.

In addition, a soft-bottom, marine-based general waste crushing facility can save on land costs because it does not occupy land, and because it operates at sea, it is less expensive than conventional crushing facilities. This allows for less consideration for such land and environmental issues.

〔Example〕

The present invention will be explained below with reference to illustrated embodiments.

The drawing shows a state in which a marine structure 1 for general waste treatment, which is a soft-bottom type and is located offshore, is sunk and installed in the sea area near a final landfill site.

The marine structure 1 for general waste treatment includes a plurality of ballast parts 2.
It consists of a caisson body 3 having a caisson body 3 and a general waste crushing facility 4 provided integrally with the caisson body 3. The general waste crushing facility 4 also includes a garbage pit 5, a crushing device 6, a sorter 7, and an iron recovery device 8.

The caisson body 3 in this embodiment is made of concrete I/(P
C', RC structure) or steel shell, and the balance of the draft box and ground pressure can be freely controlled by adjusting the ballast water in the ballast section 2.

The reference numeral 9 in the drawings indicates the foundation bottom slab, which is towed and sunk together with the caisson body 3.

After touching the ground such as soft ground, the caisson body 3 functions as a structure having a sliding vibration isolation mechanism with the bottom plate 3a of the caisson body 3.

In addition, the general waste crushing facility 4, which is integrated into the caisson body 3, is composed of a garbage pit 5, a crushing device 6, a sorter 7, an iron recovery device 8, etc., and is compared to conventional crushing facilities. , the space required is as small as possible.

The general waste crushing facility 4 consists of an atrium extending from the ceiling to the floor at a height of about 3 to 4 stories, and the roof 10 has a steel frame structure.

Marine structure 1 for general waste treatment consisting of such a configuration
Garbage disposal work is carried out as described below.

First, garbage or a garbage container 12 transported by sea by a small boat or a garbage container ship 11 is unloaded by a gantry crane 13 from a ship docked alongside the terminal of the caisson body 3.

and garbage pit 5 or garbage container pit) 5a
carried to.

Next, the crushing device 6, the sorting machine 7, and the iron recovery device 8,
The crushed and sorted bulky waste is then disposed of by being divided into direct landfill disposal, incineration, and recovered iron content.

When processing such garbage, the general waste crushing facility 4 installed on a soft-bottom offshore structure 1 does not occupy land, thereby saving land costs. In addition, because it operates at sea, there is less need to consider land and environmental issues.

In addition, since the ballast water can be freely adjusted and changed by each ballast part 2 in the caisson body 3,
At any installation position, it is possible to maintain the balance of the caisson body 3 while ensuring ground pressure to a predetermined seabed ground according to the tide level. Thereby, the influence of the buoyancy of the caisson body 3 and waves can be completely eliminated, and the general waste crushing treatment facility 4 can be kept in a movable state at all times.

Additionally, if it is no longer needed after installation, it can be resurfaced, towed, and moved to the next destination, making it possible to repurpose it and saving the trouble of disassembling and removing it on site.

Furthermore, marine transportation of garbage can be considered as a means of improving road traffic conditions by reducing land transportation and easing traffic volume. Sea transportation by garbage container ships, etc. becomes possible.

〔Effect of the invention〕

The present invention has the above configuration and has the following effects.

■ Since the marine structure for treating general waste of the present invention is installed on the sea, it becomes possible to prepare intermediate treatment facilities that are in short supply more easily than when it is installed on land. In addition, by repeating towing, sinking, operation, and resurfacing, it is possible to operate a general waste crushing treatment facility at any location on the sea, making it easy to relocate when commercializing urban development plans. It is.

■ The marine structure for general waste treatment of this invention can be constructed and dismantled within the dog, which is advantageous in terms of construction time, and since it is on the bottom when garbage treatment is in operation,
No reduction in operating rate due to waves.

■ Since this marine structure for general waste treatment will be installed in the sea near the final disposal site, the garbage will be mainly transported by sea, which will help reduce the number of land transport vehicles and ease road traffic as much as possible. I can do it.

Furthermore, transporting the intermediately treated waste to the final disposal site can be carried out by sea, making it much easier than conventional land transport.

■ The marine structure for general waste disposal of the present invention can freely control the balance and predetermined ground pressure of the caisson body by adjusting the ballast water in the ballast section. Therefore, it is possible to reduce the ground pressure on the ground where this marine structure for general waste treatment bottoms out, so there is no need for large-scale base construction for landing on the bottom.
