Description

[Detailed description of the invention] [Industrial application field] This invention relates to vegetation bases.

[Conventional technology]

Previous attempts have been made to use three-dimensional lumps with large porosity as vegetation substrates, such as plate-shaped bodies made of wire mesh, plastic nets, etc. with irregularities, and mat-like bodies made of irregularly glued plastic strings and coconut shell fibers. were seen a lot.

[Problem that the invention seeks to solve]

Although the inventor has made many attempts for this purpose, he has not yet achieved something completely satisfactory.

This has a porosity of 30 to 90%, which is the most suitable as a vegetation base.
This is because if an attempt is made to form a lump having a certain degree of compressive strength and tensile strength, the price will inevitably increase.

[Means to solve problems]

In order to solve this problem, in this invention, like the wood wool cement board used as a roof base as a building material,
The main material is wood wool with a length of IO to 30 cyn and several 11 widths, and a three-dimensional lump made by sprinkling cement or other adhesive on its surface, irregularly intertwining it, and compressing it is used as a vegetation base.

[Effect]

With this structure, it is possible to obtain an arbitrary thickness, a porosity of around 50%, no compression even when a person stands on it or mud is sprayed on it, and a sufficient strength to retain the M amount of mud even on a steep slope. ,
Furthermore, the materials and manufacturing costs are extremely low.

[Example 1] Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

As shown in Figure 1, cement milk is sprinkled on wooden wool 1 formed into several crane widths and approximately 20 cm long, mixed and tangled irregularly, and then filled into a matching net bag 2 made of synthetic resin fibers. . At this time, mix in three large slow-release fertilizers.

In order to specify the strength and size, it is compressed to a certain thickness,
After forming into a disc-shaped body A, it is left to dry and harden.

Usually, the mixing ratio (weight ratio) of wood wool and cement is 50 to 6.
0: 50-40, bulk specific gravity 0.2-0.5
It is.

The size of the disk-shaped body is usually 20 to 50 cm on the - side and 5 cm in thickness.
~10aa.

As shown in FIG. 2, such disk-like bodies are laid out on a slope and fixed to the disk-like bodies at appropriate intervals with anchor pins 4.
A slurry of ±5 mixed with fertilizer, water retaining material, and vegetation seeds is sprayed from above. When spraying only wire mesh on a slope, a shelf material such as resin or cement is mixed into the soil to prevent it from being washed away by rain.
In the case of this invention, no glue is mixed so that the disc-shaped body is well filled. Even if it is not mixed in, it is retained by the wood wool, so there is no problem.

In addition, what is shown in FIG. 3 is one in which a plurality of disk-like bodies A are attached to a large net-like object 6. The attachment can be done by passing the wire 7 through. When installing, lay it with the net-like material on top and fix it in place with anchor pins. Since a large area can be covered at once, construction is quick, and using a durable net-like material is effective in stabilizing vegetation on the slope.

As a method of attaching to a net-like object, as shown in FIG. 4, a plurality of disk-like objects A may be sandwiched between two net-like objects 6, and the net-like object may be closed at certain places.

Incidentally, a plurality of disk-like bodies may be connected by a sheet-like object or a lobe-like object.

[Example 2] As in the previous example, wood wool was sprinkled with cement milk to form compressed and bonded wood wool cement (iA'). As shown in Fig. 5, the voids of the wood wool cement board A'' cut into squares with sides of about 30 cm are filled with a vegetation base material 8 containing a mixture of soil, water retaining material, fertilizer, soil conditioner, etc. . Wrap the outside with non-woven fabric 9 to prevent the vegetation base material from falling off during transportation,
Let's call it vegetation board B.

To carry out the construction, as shown in Fig. 6, vegetation plates B are laid out on the slope, a seed sheet 10 with vegetation seeds attached to the back is laid on top of it, and then a diamond-shaped wire mesh 11 is placed over the entire surface. Hang it and secure it with anchor pin 4.

This kind of vegetation board B is filled with vegetation base material in advance, so there is no need to spray soil on site, and it is suitable for sites deep in the mountains where it is difficult to bring in a spraying machine, or where it is not economical to bring in a machine. It is convenient for application to small-area sites.

It should be noted that, of course, resin-based adhesives may be used in addition to cement milk as the adhesive used when bonding the wood wool, but cement-based adhesives are superior in terms of price. When it is desired to increase adhesive strength, it is convenient to use resin-based adhesives together.

Further, in order to increase the strength, in addition to wood wool, pieces of wood, short iron wire, etc. may be mixed.

〔effect〕

Since the present invention is configured as described above, it has the following features.

■ Wood wool cement boards use wood wool as a raw material, which is inexpensive, and because the wood wool is thick, the amount of cement needed as a whole is small.
Moreover, since the manufacturing method is simple, the cost is low.

■ It is convenient because it is possible to enclose large grains of slow-release fertilizer inside the manufacturing process, which involves sprinkling cement milk on the wood wool and then putting it into a mold.

■ The soil is held in place by the wood wool, making it stable even on steep slopes.

■ Wood wool is thicker and has more elasticity than keratin fibers, so when it is intertwined three-dimensionally, the porosity can be increased, making it possible to hold a large amount of soil and other vegetation base materials.

■ Wood wool cement boards have sufficient pressure resistance even though they have many voids, so even if a person stands on them during work or mud is sprayed on them, they will not be crushed like coconut shell mats or plastic mats. It is possible to press soil etc. inside.

■ Due to its high tensile strength, it has a great ability to retain vegetation as a vegetation base.

■ Over a long period of time, wood wool becomes humus and is returned to nature.

■Thick ones can be manufactured easily, so you can get the optimal thickness at a low price. Therefore, it can provide an ideal vegetation base.

■ Because the vegetation base material is well held by the intricately intertwined wood wool, it is possible to omit adhesives and other materials for the soil, resulting in lower costs.
