After that, the hydraulic component may be cured, in which case a part of the hydraulic component penetrates into the lower part of the sheet-like nonwoven fabric, and the planting porous concrete and the planting seeding sheet are integrally formed. Become.

As the hydraulic component, for example, portland cement, alumina cement, blast furnace cement and the like can be used. Also, if the mixing amount of the hydraulic component is too small, the binder is insufficient, and the strength of the planting porous concrete is reduced.If the mixing amount of the hydraulic component is too large, the continuous voids of the planting porous concrete are reduced. At the same time is reduced, because continuous void is closed, the mixing amount of hydraulic component is preferably to 7-22% by volume relative to the volume of the coarse aggregate, specifically a range of 150~350kg / m ³ Is preferred.

In the above-described embodiment, the crushed stone 1 is used as the coarse aggregate, but gravel, artificial lightweight aggregate, or the like can be used alone or as a mixture as the coarse aggregate. In addition, the particle size of the coarse aggregate is related to the amount of continuous voids, the size and strength of the porous concrete for planting, and should be selected according to the required strength of the porous concrete for planting, the type of plant to be planted, etc. Can be. And if the particle size of the coarse aggregate is too small, the diameter of the continuous void of the porous concrete for planting becomes small, the roots of the plant cannot pass through the continuous void, and cannot be used for planting, On the other hand, if the particle size of the coarse aggregate is too large, the joint area between the coarse aggregates is small, and the strength of the planting porous concrete is reduced. Therefore, the particle size of the coarse aggregate is preferably 5 to 80 mm, and 10 to 10 mm. 30 mm is more preferred. The amount of coarse aggregate varies depending on the specific gravity of the coarse aggregate to be used.
900 kg / m ³ , 1000-120 for artificial lightweight aggregate
0 kg / m ³ is preferred.

The soil material may be any material that has an appropriate water retention property and can grow plants. For example, peat, zeolite, perlite, bentonite, peat moss, vermiculite, soil from a water purification plant, etc. may be used. it can. Further, the mixing amount of the soil material is suitably such that the volume of the soil material occupied in the planting porous concrete is 10 to 40% by volume, and varies depending on the specific gravity of the soil material. A range of m ³ is preferred. Further, the particle size of the soil material is preferably 0.5 to 10 mm, and when the particle size of the soil material is 0.5 mm or less, the soil material is buried in the cured product of the hydraulic component, or the surface of the soil material is The function of the soil material may be hindered by being covered with the cured product of the hydraulic component.

The type of the particulate superabsorbent resin is not particularly limited, and any commercially available resin can be used. In addition, the particle size of the particulate high-absorbency resin is preferably 0.01 to 2 mm, more preferably 0.02 to 1 mm.

When the amount of the hydrogel is too small,
The hardening of the hydraulic component is slow, and it takes too long to become a self-sustaining cured product, which is not suitable for practical use.On the other hand, if the mixing amount of the hydrogel is too large, the hydraulic component, coarse aggregate, soil material and Since the mixture with the hydrogel cannot keep the dry state and the surface of the soil material is covered with the cured product of the hydraulic component and becomes useless, the mixing amount of the hydrogel is 5 to the weight of the hydraulic component. Preferably, the content is 40% by weight.
More preferably, it is 35% by weight. Also, if the amount of water impregnated in the hydrogel is too small, it takes time for the hydrogel to release water, and the hardening of the hydraulic component is delayed, while if the amount of water impregnated in the hydrogel is too large, Since the water retention of the hydrogel decreases and water is released during the mixing of the mixture, and the mixture does not become a dry mixture, the hydrogel is used by impregnating the water with a weight of 5 to 1000 times the weight of the finely particulate high-absorbency resin. It is more preferable to impregnate and use 50 to 500 times of water.

Further, in the above-described embodiment, vibration is applied to compact the mixture containing the hydraulic component, the crushed stone 1 and the soil material 2 in the hydrogel in the formwork.
There are a method of pressing with a roller and the like, and a method of using vibration and pressure together.
