  An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

  Since the wood fiber layer 1 is covered with the planting layer 2, the wood fiber layer 1 is protected without being stepped on directly, and further, the wood fiber constituting the wood fiber layer 1 is formed by rooting the plant forming the planting layer 2. They are held firmly, thus preventing the wood fibers from scattering.

  In addition, the wood fiber layer 1 and the planting layer 2 contain no synthetic resin and are all biodegradable and are therefore environmentally friendly. Furthermore, since no synthetic resin binder is used, the water permeability of the wood fiber layer 1 Is not hindered and it is difficult to collect water.

  Furthermore, the planting layer 2 allows the top surface of the wood fiber layer 1 to be covered with a plant, so that it can be finished in a very beautiful appearance, is easy on the eyes, and reduces the burden on the pedestrian's waist and knees. In addition, since the rapid temperature rise on the road surface due to sunshine can be suppressed, it is friendly not only to the environment but also to people.

  Moreover, since the plant which forms the planting layer 2 is rooted in the wood fiber layer 1, it grows well with almost no maintenance such as watering with the nutrients of the binder and the water retained by the wood fiber. Therefore, the formation of the planting layer 2 becomes extremely easy and greening can be easily performed.

  Specific embodiments of the present invention will be described with reference to the drawings.

  In this embodiment, a planting layer 2 formed of a plant rooted in the wood fiber layer 1 is provided on the upper surface of the wood fiber layer 1 formed by solidifying wood fibers with a biodegradable binder. Is.

  As the wood fiber, a small piece of wood fiber (wood chip) or fiber wood fiber (wood fiber) obtained by crushing a wood waste material generated at a construction site or the like with a crusher is used.

  As the biodegradable binder, a vegetable binder, specifically, a plant thickener (containing plant nutrients) is used.

  As the plant that forms the planting layer 2, a ground cover plant that is inexpensive, does not become too tall, and is difficult to break even when stepped on is adopted. Specifically, plants that contribute to greening such as turf and white clover (clover) may be employed.

  Hereafter, the formation method of a present Example is explained in full detail. FIG. 1 shows a flowchart of the forming method of this embodiment.

  Wood waste material is crushed by a crusher to make small pieces of wood fiber or fibrous wood fiber. In the present embodiment, wood-based waste materials (unnecessary portions other than the trunk portion that can be used as a pile, such as roots and fine branches) generated at the construction site where the pavement layer is formed are used as they are.

  In addition, by using wood-based waste materials at the construction site (local site), it is possible to easily dispose of wood-based waste materials generated on-site without the need for incineration or disposal at the disposal site. It is possible to add value to the product by clarifying the origin of the components.

Subsequently, a plant thickener is mixed into the wood fiber. Water (or warm water) is also mixed. At this time, if calcium hydroxide (Ca (OH) ₂ ) is added, the solidification rate of the wood fiber can be increased. In addition, this mixing process can be easily performed at the construction site.

  In the present embodiment, sand (fine sand or the like) is mixed to increase the density of the wood fiber layer 1 and improve the strength. Furthermore, a fertilizer is mixed in order to properly feed the plants forming the planting layer 2.

  Subsequently, the mixture is spread on a pavement excavation part provided on the ground (roadbed), and is pressed and allowed to solidify for a predetermined time to form the wood fiber layer 1 (solidification time is usually 4 to 5). 1 day when calcium hydroxide is added). In this embodiment, the thickness of the wood fiber layer 1 is about 5 cm.

  Subsequently, turf cultivated elsewhere in advance is laid on the upper surface (surface layer) of the wood fiber layer 1 (so-called turf extension).

  In this embodiment, the planting layer 2 is formed by laying (planting) grass previously grown elsewhere on the upper surface of the wood fiber layer 1, for example, as shown in FIG. As described above, the planting layer 2 is formed by a plant (turf) formed by cultivating turf seeds or turf seedlings (so-called loose grass) mixed in the wood fiber layer 1, or on the upper surface of the wood fiber layer 1. You may form the planting layer 2 using other means, such as forming with the plant which grows the sowing seed or seedling. In this case, the grass lawn can be omitted, and the planting layer 2 can be formed more easily.

  In addition, as described above, when seeds or seedlings are grown to form the planting layer 2, if sand and fertilizer are mixed when forming the wood fiber layer 1, the seeds or seedlings can be grown faster. Can do.

  The pavement layer formed by such a process has the following characteristics.

  (1) Unlike the pavement layer formed by the conventional method, because the biodegradable binder is used as the binder to harden the wood fiber, both the wood fiber and the binder are biodegraded and returned to the soil, making it environmentally friendly. Become.

  (2) The plant-based thickener used as a plant binder is particularly excellent in elasticity compared to the conventionally used synthetic resin binders, and there is a planting layer 2 formed of plants. As a result, the cushioning property is further improved and the burden on the legs and feet is reduced, making it suitable for walking paths (places) and the like.

  (3) Since the wood fiber is originally discarded, the raw material cost is extremely low, and the pavement layer can be formed at a very low cost.

  (4) By adopting a vegetable binder instead of a synthetic resin binder, the water permeability of the wood fiber layer 1 is not hindered, and a puddle does not occur.

  (5) Since the planting layer 2 is provided on the upper surface of the wood fiber layer 1, it is excellent in weather resistance.

  (6) Since the wood fiber layer 1 is protected by the planting layer 2, scattering of the wood fiber shaved by walking or the like, which has been a problem in the conventional method, is suppressed. That is, when a plant binder such as the above plant thickener is used, there is a problem that the adhesive strength is weaker than that of a synthetic resin binder, so that it tends to be eroded. The plant which comprises the plant layer 2 is rooted in the wood fiber layer 1, and this wood fiber layer 1 is hard to be eroded by rain water or a stepping foot, and the water permeability of the wood fiber layer 1 is not hindered. Etc. are very unlikely to occur.

  (7) Since the work for forming the pavement layer can be easily performed at the construction site, workability becomes easy.

  (8) Greening on wood chips or wood fibers, which has been impossible in the past, becomes possible. This is presumably because the presence of the plant binder serves to retain the fertilizer and an appropriate amount of moisture, and these can be stored in the wood fiber layer 1.

  (9) The surface layer of the wood fiber layer 1 may be coated with a synthetic resin in order to protect the wood fiber layer 1; however, in consideration of water permeability and greening, the present embodiment is implemented from this synthetic resin coating. It is desirable to protect the wood fiber layer 1 with the planting layer 2 of the example.

  In addition, this embodiment is used for parks and mountain forest trails, golf course paved roads, bicycle roads, school paved roads, and athletic open spaces.

  Since the present embodiment is configured as described above, the wood fiber layer 1 is covered with the planting layer 2, so that it is protected without being stepped on directly, and the plants forming the planting layer 2 are rooted. Thus, the wooden fibers constituting the wooden fiber layer 1 are firmly held, and thus the scattering of the wooden fibers is prevented.

  In addition, the wood fiber layer 1 and the planting layer 2 contain no synthetic resin and are all biodegradable and are therefore environmentally friendly. Furthermore, since no synthetic resin binder is used, the water permeability of the wood fiber layer 1 Is not hindered and it is difficult to collect water.

  Furthermore, the planting layer 2 allows the top surface of the wood fiber layer 1 to be covered with a plant, so that it can be finished in a very beautiful appearance, is easy on the eyes, and reduces the burden on the pedestrian's waist and knees. In addition, since the rapid temperature rise on the road surface due to sunshine can be suppressed, it is friendly not only to the environment but also to people.

  Moreover, since the plant which forms the planting layer 2 is rooted in the wood fiber layer 1, it grows well with almost no maintenance such as watering with the nutrients of the binder and the water retained by the wood fiber. Therefore, the formation of the planting layer 2 becomes extremely easy and greening can be easily performed.

  Furthermore, greening on wood chips / wood fibers, which was impossible in the past, becomes possible, and from this point, greening can be easily performed.

Therefore, in this embodiment, the scattering of the wood fiber layer is suppressed by the planting layer, and the wood fiber, the binder and the planting layer are all biodegraded. can not equal, further greening by planting栽層also possible and, moreover, like performed without the hassle of green-reduction, the method for the formation of very practical breakthrough was soo is in walking for shop Soso Become.

It is a flowchart explaining the formation method of a present Example. It is a flowchart explaining the formation method of another example. It is a use condition figure of a present Example.
