Description

[Detailed description of the invention] The present invention relates to the invention of a vegetation substrate for a lawn waterway, and more specifically, it can be used as a complete drainage channel until plants grow, and after the plants grow. This invention relates to a vegetation substrate for grass channels that is aesthetically pleasing and can be used as an increasingly strong drainage channel.

Traditionally, grass canals have been frequently used as waterways in mountain conservation, but the common method for making grass canals is to use wild grass that grows locally and attach it to the bottom and sides of the waterway. Ta.

However, these days, there are few places where wild grass grows locally, and so-called live grass, such as grown wild grass, has to be transported to the site, which is very expensive, and the cut grass has to be pasted into waterways one by one. However, it has the disadvantage of poor workability.

Attempts have been made to attach artificially created vegetation substrates called turf belts to waterways, but if it rains soon after the turf has been affixed, that is, before the vegetation has grown, the grass Normally, water does not flow through the canals, but once it rains, enough water will suddenly start to flow, filling the canals, causing the phenomenon of turf being washed away. Ta.

The present inventors were conducting research to create a vegetation base for grass channels that could function as a water channel even if it rained while no vegetation was growing. We focused on room-temperature paving material because it is hardened into a plate-like material that allows vegetation to grow on it, and arrived at the present invention, believing that using this material would create an ideal substrate for vegetation in grass channels.

The configuration of the present invention will be explained in detail below based on the drawings.

The bag constituting the vegetation substrate of the present invention is not limited to either vegetable or chemical materials as long as it has a texture that allows the germination of plants.

This bag body is usually a single body, but one bag body 1
As shown in FIG. 1, it is better to separate the three-layer structure by sutures 2, so that both sewn ends are located at the sides and the middle is located at the water channel section 3 at the bottom.

There are two types of bag slots: one that closes with a chuck and one that closes with a string.

This bag is filled with seeds, room-temperature paving material, and vegetation base material.

Room-temperature paving material is a material in which aggregate and asphalt are mixed using a heated mixing method or a room-temperature mixing method, and then a light component oil is sprinkled or sprayed on the surface of the aggregate covered with asphalt. It is then coated again with a light component oil.
The light component oil referred to here is petroleum distillate, with a specific gravity of
0.85-0.90 flash point 135° or more, aromatic ingredients 10
% or more of oil content.

When this room-temperature paving material is subjected to compaction, the asphalt and light component oil melt into one another and become the same, fixing them together, but it also leaves voids in which plants can grow.

If the room-temperature paving material is simply mixed with seeds, the growth will be poor, so a vegetation base material is mixed.

This vegetation substrate refers to organic materials (bark compost,
peat moss, etc.) Fertilizer, water retention material, soil improvement material, among which organic materials are always mixed, and one or more of the above are mixed into this.

A bag filled with a mixture of the above-mentioned seeds, room-temperature paving material, and vegetation base material is placed in the waterway area, and the construction is carried out by compacting it.

Then, the room-temperature paving material solidifies and becomes plate-like with some voids, creating a complete waterway.

As described above, the present invention is a vegetation substrate for a lawn waterway that contains plant seeds, room-temperature paving material, and vegetation substrate in a bag with a size that allows plants to germinate and grow. Once solidified, the vegetation base for grass channels becomes plate-shaped and can function as a canal by itself, and even if it rains before the vegetation grows, the vegetation base will not be washed away. There is a marked difference compared to Harizhi belt.

In addition, it is easy to construct, stable, and has the strength of a concrete board that has been laid down and compacted.
Moreover, since it allows plants to grow, it is ideal as a lawn waterway, and can be applied not only to mountain conservation but also to general slope drainage.

[Brief explanation of the drawing]

FIG. 1 is a perspective view of a three-layer vegetation substrate for a lawn waterway according to the present invention. FIG. 2 is a perspective view showing the vegetation substrate for turf waterways laid in a waterway. In the figure, 1 is a vegetation base for a lawn waterway, 2 is a sutured portion, and 3 is a waterway.
