Means for Solving the Problems The slope greening method of the present invention is a method of arranging a supporting member made of wood as a shelf or a staggered pattern on the ground, and continuously connecting the ground and the supporting member. It is characterized in that a lump of foamed glass having bubbles is laid and a soil layer covering the support member and the lump is formed. Here, arranging in a shelf shape means arranging the supporting members so as to form a continuous shelf in the lateral direction on the ground, and arranging in a staggered manner means that a plurality of supporting members are arranged vertically and horizontally on the ground. In a row of vertically adjacent support members, the support members and the spaces therebetween are alternately arranged in the upper and lower rows.

In the support member made of wood, the wood fibers have appropriate water absorption and water retention properties, and the lumps of foam glass have a large number of open cells, so that ground water, rainwater, etc. Is appropriately absorbed, since it has a function of permeating excess water, the support member is arranged in a shelf shape or a staggered shape on the ground, and a lump is laid between the ground and the support member. By forming the soil layer covering these, the soil layer is firmly fixed by the support member placed on the ground, so that the soil layer is prevented from flowing out and collapsed, and excellent water retention is exhibited. The water content necessary for plant growth and the nutrients contained in the water can be retained for a long period of time, and a green slope with good plant growth can be constructed.

Here, the support member can be manufactured by using general wood, but it is preferable that it is manufactured by using thinned wood, which allows thinning that has been left on the sloped surface of the mountain area. It is possible to effectively use the timber, and it is possible to prevent the harmful effects of the thinned timber from driftwood. In addition, the lumps can be manufactured from new glass materials, but can also be manufactured from discarded empty bottles and glass waste materials as raw materials, so effective use of glass resources is aimed and illegal glass waste materials can be produced. The dumping can be reduced and it can contribute to the protection of the natural environment.

Here, the soil layer may be formed by spraying a base material containing foamed glass granules having open cells, compost, plant seeds, and an adhesive material onto the ground to cure the base material. it can. By spraying and hardening such a base material, the surface of the soil layer has an appropriate hardness that allows plants to grow, and the hardness is not only maintained for a long time after the completion of construction, but In the layer, due to the action of the adhesive material contained in the base material, foamed glass granules, compost, plant seeds, and the like are solidified together to form an aggregated structure. It is possible to construct a greening slope with excellent durability without erosion of the ground and scattering of the base material due to wind. Further, since this soil layer can maintain an appropriate water retention property even in the dry season, the plant does not die and a stable growth state can be secured.

In addition, since the base material forming the soil layer contains the foamed glass granules, gaps necessary for growing plant roots and shoots are secured inside the soil layer. After the construction is completed, the germinated plant seeds can grow from the surface of the soil layer to the outside while absorbing nutrients contained in compost, etc. . This granular material is made of foam glass having a large number of minute open cells, is relatively lightweight, has a function of appropriately absorbing groundwater, rainwater, etc., and has a function of allowing excess water to permeate. Even after a long period of time, the initial lightweightness is not lost, and the outflow or collapse of the soil layer can be prevented.

Further, since the foamed glass granules have continuous air bubbles from the outer periphery to the inner portion thereof, they serve as a beneficial habitat for soil microorganisms in the soil layer, and the activity of these plants also activates the growth state of the plant. To be done. Since these granules are glassy, they are chemically stable, and elution and corrosion of harmful substances do not occur, so there is no risk of environmental pollution and they have excellent durability. Since the foam glass granules can be manufactured not only from new glass materials, but also from discarded empty bottles and glass waste materials as raw materials,
It is possible to make effective use of resources and contribute to the protection of the resource environment.

As compost, fallen leaves, straw, dust,
A mixture of organic substances made by stacking and decaying wild grass is suitable, and it is a nutrient source when the plant seed contained in the soil layer grows, and also enhances fertilizing ability, water retention and air permeability. Since it has the effects of improving plant growth and promoting the activity of soil microorganisms, a good plant growth base can be formed. In this case, plant growth can be further promoted by adding various chemical fertilizers to the base material.
