Abstract

PURPOSE:To eliminate trouble with acquirement of site for the incinerator plant for wastes as well as to facilitate the constrction of the plant by a method in which a floating structure having an incineration system inside is towed to a site on water and settled on the foundation mound provided on the seabed. CONSTITUTION:An incineration system 7 consisting of an incinerator furnace, a waste heat boiler, etc., is installed in a floating structure 5. The structure 5 is floated on water, settling apparatus, e.g., jack 8, etc., is attached to the bottom of the structure 5, and the structure 5 is towed to a construction site for wastes- incinerating plant. The floating structure 5 is then settled on the foundation mound 10 of the seabed, and cement mortar 12 is poured into the space between the structure 5 and the seabed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for constructing a garbage incineration plan I on the sea close to the coast.

Traditionally, garbage incineration plants have often been built in mountainous areas or near the coast. When constructing in a mountainous area, as shown in Figure 1, the ground (α) is excavated and a foundation (b) is constructed, and a garbage incineration plant (c) is constructed on the foundation (b).
The rice husks produced by the incineration were dumped at another site. In addition, when building near the coast, as shown in Figure 2, fill in land (d) on the coast, then excavate a portion of the reclaimed land (d) and place the foundation on the sea bottom ground (1). Construct (f), build a garbage incineration plant (c) on the foundation (f),
The rice husks were dumped at another site.

In this way, when conventional garbage incineration plants are built in the mountains, it is difficult to obtain plant land and land for dumping rice husks, and when built near the coast, it takes a long time to fill up the waste and it takes a long time to complete the plant. The whole process was long and involved a lot of on-site construction, and it was also necessary to find a separate land for dumping the chimneys.

The purpose of the present invention is to reduce the on-site construction work and shorten the construction period when a landfill site can be secured near the coast, and to eliminate the need to separately seek land for dumping chile husks. A waste incineration plant that forms a structure, installs incineration system equipment therein, floats a floating structure above water, creates a foundation mound on the bottom of the water, and then tows the floating structure onto it and sinks it. This concerns the construction method.

Next, an embodiment of the present invention will be described. As shown in FIG. 6, a steel shell caisson (2) is assembled at a shipbuilding dock (1,) or a slipway on land. At this time, the steel shell caisson (2) is reinforced with a steel frame or the like. While there is a steel shell caisson (2) inside the shipbuilding dock (1),
If necessary, as shown in Fig. 4, a part of the bottom plate or a part of the garbage bit part etc. may be installed inside the steel shell caisson (2).
) (3) and assemble the chimney (4) etc. In this way, the floating structure (
5) is formed.

After launching this floating structure (5), as shown in Figure 5, it is moored to the quay (6) and the floating structure (5) is kept floating. pour concrete,
Incineration synutem equipment (7) such as an incinerator or waste heat boiler is installed inside the floating structure (5).

In some cases, it may not be necessary to place concrete inside the steel shell caisson (2), and after installing part of the Kg cooling system equipment 7) in the floating structure EL (5) on land, the floating structure (5) may be floated on the sea.

After attaching sinking equipment such as a jatsugi (8) to the bottom of the floated structure (5) as shown in Figure 6,
Tow it to the garbage incineration plant construction site 1 using the towing device (9).

On the other hand, on the seabed near the coast where the garbage incineration plant will be constructed, a foundation mound (10) of pile foundation, cell foundation, gravel foundation, etc. will be constructed as shown in Figure 7. Attach the temporary support (11) that has been made. The floating structure (5) that has arrived at this construction site is sunk onto the foundation mound (10) by utilizing the tidal difference in the sea surface. Next, mortar θ2) is injected into the space created between the bottom of the floating structure (5) and the seabed as shown in Figure 8, and after the mortar θ has hardened, the floating structure (5) The support of the entire load of is replaced by the molarity (I2). Horizontal force and buoyancy caused by earthquakes or wave forces can be countered by the loads of water ballast or embankments (13) around the floating structure (5), sheds (14) installed on the floating structure (5), etc. make them resist.

Finally, as shown in FIGS. 9 and 10, a connecting bridge 07) is attached to the loading road (16) on the land (15) for the garbage truck to access. In order to use the husks and solidified dust after incinerating the garbage for reclamation in the surrounding area, conveyance devices such as the Reto conveyor α mark are installed inside and outside the floating structure (5), as shown in Figure 10. The sea side (
In I■, a breakwater (20) will be constructed to reduce the impact of large waves such as those caused by typhoons.

The present invention has the following effects.

■ Garbage incineration plants can be constructed without land shortages on land.

■ Civil engineering construction work at the building site can be reduced.

■ Noise and landscape problems at the construction site can be eliminated.

■ After incinerating garbage, the rice husks can be used for landfill in the surrounding area.
