Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention introduces plants into artificially constructed bare land, hillside slopes collapsed by a disaster, and slopes such as rocks of inorganic recessive soil. In order to form a vegetation base that is constructed prior to the so-called slope greening work, which protects and protects greenery, the incinerator ash that remains after incineration of industrial waste and household waste that can be burned by an incinerator is recycled. It is intended to be used as a base material for vegetation in slope greening work.

[Conventional technology]

The applicant has already proposed a method of blending konjak flying powder as an adhesive material in addition to fertilizer to the base material for forming the vegetation base, and adding water to this to spray a slurry on the slope. Yes (Japanese Patent Publication No. 54-1364, Japanese Patent Publication No. 60-46923)
No. 6, JP-B-62-1050, JP-B-62-21937, JP-A-61-18
2316 publication).

As the above-mentioned greening base material, black soil or mountain sand is used, and a fertilizer, an adhesive material and the like are mixed therein. As the fertilizer, lime, chemical fertilizer or coated fertilizer is used. Konjac flying powder mixed as an adhesive material is also useful as a delayed-release fertilizer.

In actual construction, in addition to the above materials, peat moss may be mixed as a soil improving material.

[Problems to be Solved by the Invention]

However, since the above-mentioned peat moss is an imported product, the cost is high. Therefore, a substitute material for this has been sought, but there is no suitable one at present. The black soil used as a vegetation base material is stable in quality, but is expensive and difficult to mine and procure due to its short supply.

Further, the mountain sand of the vegetation base material has the advantage that it is easier to mine and procure than the above-mentioned black soil, but has the drawback that uniform construction effects cannot be obtained due to variations in quality and lack of stability. .

In addition, it is necessary to prepare a large amount depending on the spraying area and spraying thickness in a vast construction site, and the construction cost required for procuring that much is required, and the collection of black soil and mountain sand requires cutting of herbs and root moats. As a result, it also causes the destruction of the natural environment such as the mining site and the surrounding landscape.

On the other hand, a large amount of industrial waste and household waste is generated every day, and in order to process this, burning waste is incinerated in an incinerator device, but since the incinerated ash left after incineration is useless, At present, it is transported to a remote place where there is not much obstacle to environmental destruction, digging holes, filling it up, or dumping it into the ocean, which requires a lot of manpower and time, and it costs a lot of money. There was a problem.

[Means for solving the problem]

Therefore, the present invention was generated by eliminating the use of black soil and mountain sand at the time of forming the vegetation base in the conventional slope greening work, and instead incinerating combustible industrial waste and household waste in an incinerator. It is an object of the present invention to solve the above-mentioned problems by utilizing the incinerated ash as it is without being subjected to secondary processing such as granulation and mixing and stirring it with other spraying materials.

In order to achieve the above object, the present invention is a method of forming a greening foundation by recycling, in the coating fertilizer or compost and konjak flying powder, a large amount of combustible food processing residue and industrial waste such as fish meat ara Alternatively, incinerator ash obtained by incineration of domestic waste such as raw urine and purified sludge is added as it is, stirred and mixed, and water is added at the time of nozzle injection using a mortar sprayer so that the ground has a predetermined thickness. The vegetation base layer was formed by spraying on.

〔Example〕

FIG. 1 is a vertical sectional side view in which the present invention is applied to a slope, and FIG.
The figure is a systematic diagram of a process for converting combustible waste, which is a component of the present invention, into incineration ash.

In FIG. 1, the material for forming the base layer 2 by spraying on the natural ground 1 is the incinerated ash generated by incineration of combustible industrial waste or domestic waste, coated fertilizer or compost as it is. And konjak flying powder are mixed with stirring, and water is added to this when spraying.

The fertilizer, which is one of the materials forming the base layer, contains fine granular solid advanced chemical fertilizer and lime fertilizer. In addition, as the compost, for example, sand sewage particles that are relatively free-flowing by using public sewage sludge in a fermenter equipped with a fermenter (for example, manufactured by Kyowa Kako Co., Ltd.) to be completely aged are used. And the compost is
It is organic, contains fertilizer components, and also has the function of neutralizing acidic soil.

Further, konjak flying powder has the function of an adhesive and the function of a fertilizer to prevent soil erosion, and is called PEMZAI (registered trademark), which is the most suitable powder fertilizer produced during the purification of konjak powder. As long as it is a pure plant having the above-mentioned function, a similar substance may be powdery or granular. The general component (%) of the flying powder is as follows.

・ Moisture 13.64 ・ Crude protein 14.30 ・ Crude fat 0.48 ・ Ash content 8.26 ・ Fiber 5.13 ・ Soluble nitrogen-free 58.19 Burnable waste incineration ash, which is the main component forming the base layer 2, contains a large amount of food processing residue. There are industrial wastes such as ara of fish and meat and domestic wastes such as live urine and purified sludge, which are dried by a dryer and then incinerated by a known incinerator device.

As the above-mentioned incinerated ash, it is also possible to use one that has been previously subjected to a combustion treatment at another place, for example, a combustion slag obtained by incinerating a pulp slag such as lignin, hemicellulose, or pectin produced in the pulp manufacturing process.

Although the particles of the incinerated ash differ depending on the material of the waste, it is suitable that the particles are processed into fine particles that are literally sand-like, like mountain sand.

In other words, the mountain sand conventionally used for forming a greening base has a large number of small particles, and a large number of small particles causes less scattering when sprayed by a mortar spraying machine. It is possible to sort it into 5.0 mm. Then, it was confirmed that the ash remaining after incineration of the various wastes described above falls within the range of the particles obtained by sieving the sand.

Of the above-mentioned wastes, for example, a process example of processing live urine will be described with reference to FIG.

That is, the raw urine in the receiving tank 11 is sent to the storage tank 13 through the pretreatment device 12 by the pump P ₁ .

Next, it is pumped by the pump P ₂ into the precipitation tank 15 through the aeration tank 14 and further sent to the coagulation precipitation tank 17 through the catalytic oxidation tank 16. Then, after being sent to the sludge storage tank 18 by the pump P ₃ , the dehydrator 19 is dehydrated by the pump P ₄ and further dried.
It is sent to 20 for drying and then sent to the incinerator device 21.

The incinerator device 21 burns urine by drying it with heavy oil and burning it. In this case, the flue gas generated by incineration is sent to the deodorizing furnace 22 after passing through the dryer, and then discharged from the chimney 23 to the outside.

Then, the incineration ash left by the incineration in the incinerator device 21 is taken out and used as it is without any modification.

"Execution example of vegetation base" Explaining the execution example of the vegetation base according to the present invention, the mixing ratio for forming the base layer per spraying thickness of 10 cm and spraying area of 100 m ² is as follows.

Coating fertilizer (slow-acting fertilizer = Product Name: high control 180,700, etc.) or flying powder of compost 15kg · konjac (Biemuzai = registered trademark) of 255kg · burning waste incineration ash 20m ³ · water 2,000~2,500l of the above For construction work with the mixing ratio, fluff and wood chips on the slope should be removed.

Then, the above material is charged into an existing mortar spraying machine by a belt conveyor or a shovel, and compressed air from a compressor is sent to start spraying by an injection nozzle. At this time, the water sent from the power sprayer is added at the nozzle portion and mixed and sprayed substantially uniformly on the natural ground 1 to form the vegetation base layer 2 having a predetermined thickness.
