CONSTITUTION:A caisson 3 is manufactured in a manufacturing place different from where it is to be installed, and is floated, forming a floating structure, to construct a excreta disposal facility. Then, a sewage disposing equipment consisting of a sewage receiving vessel 11, a pump chamber 12, a settling tank 13, a aeration tank 14, a stirring tank 15, an electric dust collector 17, etc. is installed in the floating structure 9, which is towed to a defined place and moored and installed. Thereby, a movable excreta disposal facility can be manufactured in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method of constructing a human waste treatment facility, which makes it possible to solve many problems in the construction site.

[Conventional technology]

Conventionally, when building a human waste treatment facility, as shown in Figure 9, the ground (,) at the site where the construction is to be carried out is excavated and the foundation (b) is built.
], and the human waste treatment facility ('c) was constructed on the foundation (6).

Inside the human waste treatment facility (c), there are a human waste receiving tank (d), a sludge storage tank (1), a pump room (f), an incineration room (g), etc., and the treated water is sent to a discharge culvert (not shown). It was being released through.

[Problem that the invention seeks to solve]

By the way, in the past, when building such human waste treatment facilities, it was difficult to secure land due to opposition from local residents and skyrocketing land prices, so they were often built on the outskirts of cities. As a result, the start of construction was delayed, which lengthened the construction period until the treatment facility was completed and fully operational.Also, the distance for transporting human waste was long, and the area for handling human waste was limited, making it impossible to achieve a wide-area solution. Ta.

The present invention reduces disputes related to pollution on site to avoid opposition from local residents, reduces construction work on site to eliminate problems such as noise, speeds up the construction period, and allows construction to begin while resolving local concerns. It can be used as a movable facility to serve multiple regional purposes, solving the problem of land-based land. A method for constructing a human waste treatment facility is provided.

[Means for solving problems]

The present invention manufactures a caisson at a manufacturing location different from the location where the human waste treatment facility is to be constructed, floats this caisson to form a floating structure, and installs human waste processing equipment within this floating structure. , a method of constructing a human waste treatment facility in which the vessel is towed and moored to the site where the human waste treatment facility is to be constructed.

[For production]

In the present invention, a caisson is manufactured at a manufacturing site different from the site where the human waste treatment facility is to be constructed, and the caisson is floated to form a floating structure and the human waste treatment equipment is installed. It will be towed and moored, and will become a human waste treatment facility when it is completed.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. As shown in Fig. 1, planks (2) are lined up at a shipbuilding dock (1), an onshore dock, a slipway, etc., and a steel shell caisson (3) is assembled. This shipbuilding dock (1) has a human waste treatment facility installed at a shipyard or the like different from the construction site.

The steel shell caisson (3) is reinforced with bulkheads (4) or steel frames,
A buoyancy tank (5) is installed, and if necessary, some concrete such as the bottom plate concrete (6) is poured, and van items such as mooring bollards (7) and mooring winches (8) are installed.

After the floating structure is formed in this way and launched into the water, the floating structure (9) is placed on the quay Q0 as shown in Figure 2.
While the floating structure (9) remains floating, the air receiving tank αη, pump room @, sedimentation tank A3, aeration tank α Kiku, stirring tank (G), etc. necessary for the human waste treatment facility are installed. After making various types of concrete by pouring concrete from a concrete pump truck, we installed pumps, incinerators, electrostatic precipitators αη, etc. as human waste treatment equipment, and then built a shed on the deck. Install the control room DI, chimney (a), etc.

In this way, the floating structure (9) with the human waste treatment equipment installed is towed by the tugboat Qυ as shown in Figure 3 to the construction site of the human waste treatment facility, and the floating structure (9) with the human waste treatment equipment installed is towed to the construction site of the human waste treatment facility as shown in Figure 4. If the floating structure (9) is moored at the site with a chain (a) and a concrete anchor or steel anchor, this floating structure (9) can be used as a human waste treatment facility. Human waste is transported from various locations by transport ships (c), received by pumps into the floating structure (9), and treated, after which the earth, sand, miscellaneous matter, sludge, etc. are incinerated, and the purified water is discharged into the sea.

This floating structure for human waste disposal (9) can be towed by a tugboat Q°C (see Figure 3) as needed and moved to the required human waste processing area to perform the human waste processing function in each region. .

The buoyancy tank (5) is provided on the outer periphery of the floating structure (9), and also on the bottom if necessary, to provide buoyancy to the entire floating structure (9) and at the same time adjust the inclination of the floating structure (9). Therefore, ballast water can be filled appropriately.

The above embodiment is a shipbuilding dock (1) with a steel shell caisson (3)
However, the caisson does not necessarily have to have a steel shell, and as shown in Figure 5, the bottom (a),
The side (-) side is made of reinforced concrete, the side (e) is secured with the required height when levitating, and the minimum necessary concrete beams (b) are placed for strength during levitation. A floating structure (9) that can be used as a human waste treatment facility can also be completed in the order shown in Figures 2 to 4 by fabricating a reinforced concrete caisson.

Also when mooring a floating structure (9) towed to the site,
Instead of using chain shackles and concrete anchors (2) as shown in Fig. 4, mooring can be done with metal fittings (to) installed on the quay as shown in Figs. 6 and 7, or as shown in Fig. 8. As shown, it can also be moored using a rubber suction plate Op installed on the quay.

〔Effect of the invention〕

In the present invention, the caisson is manufactured at a manufacturing location such as a dock that is different from the location where the human waste treatment facility is to be constructed, and the caisson is floated to install the human waste treatment equipment, so there is a noise problem at the location where the human waste treatment facility is to be constructed. This makes it possible to resolve local concerns while at the same time proceeding with construction work at the production site to speed up the construction period, reduce disputes regarding pollution at the construction site, and avoid opposition from local residents. In addition to solving the land shortage, it can be used as a movable human waste treatment facility in multiple areas.
