Description

The present invention belongs to a technique related to protection and handling of plants such as lawns.

There are golf courses, playgrounds, parks, gardens, factory roadsides, and various site spaces as open spaces where lawns and other plants are nurtured. The lawn is placed in the breeding ground and cut into squares from the field soil, or cut into long strips, and then rolled and stretched in place.
Grass growth is hindered when shoots are damaged by human pressure. For this reason, various frame bodies composed of a treading portion and a water permeable portion have been proposed in order to protect it from treading pressure (for example, JP-A-2-145137).
Lawn is important to supply air along with fertilizer, watering, and sunshine during its growing process, and conventional lawn has not been devised to supply air.

JP-A-2-145137

The present invention provides a lawn material that can supply air to the lawn with protection from the stepping pressure of a person walking on the lawn and can easily be handled.

The first invention is a flexible sheet, and the sheet surface is provided with a large number of protrusions on the sheet surface, and the sheet surface surrounded by the protrusions is provided with a through-hole as a lawn growing part. The sheet is laid on the field soil, and the area surrounded by the projections is filled with lawn or soil containing lawn seeds, and the lawn grown on the sheet is separated from the field soil together with the sheet. It is the obtained lawn material. Protruding parts were provided to reduce the treading pressure from people, and the treading parts received the treading pressure. At the same time, in order to spread a wide range of lawns in a short period of time, the sheet is made of a flexible material and can be rolled up.
The second invention is a flexible sheet, wherein the sheet surface has a large number of protrusions that are open to the sheet surface and closed at the other end, and the sheet surface surrounded by the protrusions has a lawn. A through hole is provided as a growing part of the grass, the sheet is laid on the field soil, and the area surrounded by the projecting part is filled with lawn or soil containing lawn seeds and grown on the sheet It is lawn material obtained by separating the sheet from the field soil. Protruding parts were provided to reduce the treading pressure from people, and the treading parts received the treading pressure. At the same time, in order to supply air to the lawn, a hollow was formed in the protruding part, and the sheet was made of a flexible material and rolled up to carry a wide range of lawn at once.

The first invention is
1. Since the protruding portion is made of a flexible material, the treading pressure of the lawn can be reduced because the protruding pressure does not decrease to the seat surface even when the treading pressure is received.
2. Since the entire sheet is a flexible material, it can be rolled and transported.
In the second aspect of the invention, since the protruding portion is further hollow, when the person steps on the upper portion, the air in the protruding portion is pushed out and supplied to the lawn.

Hereinafter, the first invention will be described in detail with reference to the drawings.
FIG. 1 is a front view and a cross-sectional view showing the concept of lawn materials constituting the present invention.
As shown in FIG. 1, the lawn material is provided with a large number of protrusions on the sheet surface, and through holes are provided on the sheet surface surrounded by the protrusions. The projecting portion is shown as a solid rod shape, but it may be cylindrical. Any shape that can receive the treading pressure is acceptable.
The area surrounded by the protrusions is filled with soil, and is a growing part such as lawn. Made of flexible resin such as rubber, elastomer or soft vinyl chloride so that the whole is rounded. FIG. 1a is an example in which only the lawn material is used, and FIG. 1b is an example in which a protection sheet for civil engineering made of a nonwoven fabric or a woven fabric is laid under the lawn material.

FIG. 2 shows a state where the lawn material is laid on the field soil and the like, and the growing section is filled with soil, lawn seeds, fertilizer, and the like. It is the same as the above that a and b of a figure have shown the presence or absence of the protection sheet for civil engineering. The same applies to the following.

FIG. 3 shows a state where the grown lawn is trimmed at the upper end and prepared for shipment.
FIG. 4 shows a state where the grass in the state of FIG. 3 is separated from the field soil in order to ship. Cut the roots of the lawn that extends into the field soil and use it as a sheet with lawn. When the civil engineering protection sheet is used, it is preferable to separate the civil engineering protection sheet from the field soil because the grass roots are entangled in the civil engineering protection sheet and the lawn is not damaged.

FIG. 5 is a conceptual diagram in which a lawn-equipped sheet is rolled up to be transportable.
FIG. 6 shows a state where the sheet is carried to a predetermined place such as a park to be greened and spread again. In this lawn material, the projecting portion supports a person's treading pressure in a laid state, and prevents a treading pressure from being directly applied to a lawn shoot or the like.

Hereinafter, the second invention will be described in detail with reference to the drawings.
FIG. 7 is a front view and a sectional view showing the concept of the lawn material constituting the present invention.
As shown in FIG. 7, the lawn material has an opening on the sheet surface, and a plurality of hollow protrusions whose upper ends are closed are provided on the sheet surface, and on the sheet surface surrounded by the hollow protrusions, A through hole is provided. The area surrounded by the hollow protrusions is filled with soil and becomes a growing part such as lawn. Made of flexible resin such as rubber, elastomer or soft vinyl chloride so that the whole is rounded. FIG. 1a is an example in which only the present lawn material is used, and FIG. 1b is an example in which a civil engineering protection sheet is laid on the lower part of the present lawn material.

FIG. 8 shows a state where the lawn material is laid on field soil and the like, and the growing section is filled with soil, lawn seeds, fertilizer, and the like. It is the same as the above that a and b of a figure have shown the presence or absence of a protection sheet. The same applies to the following.

FIG. 9 shows a state where the grown lawn is trimmed at the upper end and prepared for shipment.
FIG. 10 shows a state where the grass in the state of FIG. 9 is separated from the field soil for shipping. Cut the roots of the lawn that extends into the field soil into a sheet with lawn. The handling of the protective sheet is the same as in the first invention.

FIG. 11 is a conceptual diagram in which a lawn-equipped sheet is rolled up and transported.
FIG. 12 shows a state where the sheet is carried to a predetermined place such as a park to be greened and spread again. In this lawn material, the protruding part is hollow in the laid state, but it is not completely crushed. Furthermore, since the protrusion is hollow, every time a person walks on it, the air in the hollow protrusion is pushed out and blown onto the lawn.

In FIG. 13, a water retention sheet, a protection sheet, and a root prevention sheet are laid on the lower side of the sheet so that the lawn roots are not dried at the time of shipment. If necessary, water supply pipes for the growing lawn can be arranged between the protruding portions on the sheet. The arrangement of the water retention sheet, the root prevention sheet, the piping, and the like can be similarly performed in the first invention.

FIG. 14 shows a rod-shaped prevention by providing a gap to the extent that air can flow in and out of the inside of the hollow protruding portion so that the hollow protruding portion is not crushed by the pressing pressure in order to further protect the lawn from human stepping pressure. The state which inserted the tool is shown. The preventive tool has a protrusion at a position where it can be inserted into the hollow protrusion of the lawn material as shown in FIGS. 15 and 16, and has a through hole at a position corresponding to the growing part of the lawn material. Can be used.
