Description

[Detailed description of the invention] Industrial application field This invention relates to a gravel laying pine used when laying gravel such as Nachi Kuroishi in a garden.

BACKGROUND ART Conventionally, in order to enhance the beauty of home gardens, various places, gardens of historical sites, etc., a method of spreading gravel on top of the soil has been adopted. However, in order to prevent the phenomenon that when gravel is spread on top of the soil, it gets buried in the soil over time even if it is never stepped on, we have no choice but to add gravel periodically. This means that it will have to be installed. In addition, while exposed to the wind and rain for many years, soil and moss adhere to the gravel, and if gravel is laid directly on top of the soil, weeds often grow between the gravel, creating an aesthetically pleasing garden. In order to preserve the soil, it became necessary to wash the gravel and remove weeds, which required a great deal of labor.
In order to solve these problems, it has traditionally been done to put concrete on top of the ground, but in this case the properties of the soil change, fertilizer cannot be applied, and moisture is lost. The drawback was that it was not possible to plant trees because the soil was not sufficiently distributed. Furthermore, it is extremely difficult for amateurs to lay concrete in ordinary homes, taking into account the slope for water drainage.

Problems that the invention aims to solve This invention eliminates the above-mentioned disadvantages that occur when gravel is laid directly on soil, and also has a simple structure of gravel that does not have the disadvantages that would occur when it is covered with concrete. The purpose is to provide mats for laying.

Means for Solving the Problem This invention is based on a gravel laying pine, which is characterized by having a large number of short cylindrical pillars erected on the bottom surface of a mesh plate in which many holes smaller than the diameter of the gravel stones are formed. It depends.

Embodiments Hereinafter, embodiments of this invention will be described in detail with reference to the drawings. FIG. 1 shows a cross-sectional view of a gravel laying pine according to an embodiment, in which 1 is a net plate, on which a large number of holes 4 having a diameter smaller than the diameter 3 of gravel stones 2 to be laid are formed, Reference numeral 5 denotes a short cylindrical column, which is erected between the lower surface 6 of the net plate 1 and the ground 7. In this embodiment, the mesh plate 1 is shown in a second perspective view.
As shown in the figure, it is made up of plates in which grains 8 are combined in a lattice shape, and the inside of each lattice frame is configured as a hole 4 having a diameter smaller than the diameter 3 of the gravel stone 2 to be laid. Therefore, the interval between each grid is made smaller than the diameter 3 of the gravel stones 2. Of course, the present invention is not limited to the mesh plate 1 made of the grid-like grids 8, but may be a so-called punching board in which a large number of round holes are formed in the plate. In this case as well, the diameter of the hole is 2
Needless to say, the diameter must be smaller than 3. On the other hand, the cylindrical short pillar 5 is a hollow cylinder or a hollow prismatic pillar cut short, as shown in the perspective view of FIG. 3 or 4. It is also possible to form saw blade-like unevenness on the lower surface that comes into contact. When laying the mat, first cylindrical short posts 5 are set up at appropriate intervals as shown in the perspective view of FIG. Furthermore, gravel stones 2 are laid on top of the mesh plate 1.
If the area where the gravel stones 2 are to be laid is wide, short cylindrical pillars 5 are erected across the entire surface, and the mesh plate 1 is
Prepare a large number of sheets, connect them horizontally, and spread them over the entire surface. As a specific example, a polypropylene net with each grid mesh of 3 mm, thickness of 3 mm, and area of 1 square meter is used as a unit as a net plate, and a short cylindrical column with a diameter of 70 mm, an inner diameter of 64 mm, and a length of 50 mm is used.
It is conceivable to use a vinyl chloride pipe of mm in length as a unit, and to place short cylindrical pillars erected at intervals of 50 mm on which the above-mentioned net plate is placed. The mats laid in this way keep the gravel stones 2 floating above the ground 7, so they do not bury themselves in the soil over time, unlike when gravel stones are laid directly on the ground. Moreover, even when exposed to rain and wind, dirt does not stick to the gravel stones, rather the dust and soil adhering to the gravel stones are washed each time, which is convenient. Also, mesh plate 1
When the gravel stones 2 are laid on top, sunlight is blocked and does not reach the ground 7, which prevents weeds from growing.On the other hand, when you want to plant trees, you can remove the net 1 for the necessary sections. Just plant it. In addition, the following are listed as embodiments. First of all, as mentioned in the above example, the mesh plate 1 and the short pillars 5 are made of synthetic resin. It is convenient to use synthetic resin as the material because it does not corrode and the color can be appropriately selected to correspond to the gravel stone. In particular, vinyl chloride pipes have various standards, are easily available, and are easy to process, so they are most suitable for use as the material for the short columns 5. In a second embodiment, the net plate 1 and the short columns 5 are not made independent of each other, but are formed integrally from synthetic resin.
In this case, it is sufficient to simply lay down the mesh board 1 and the short posts 5, which are integrated, as they are, which simplifies the effort required to lay the mats. Since there is no possibility of slipping on the gravel stones 2, it is safe for people to walk on the gravel stones 2. As a third embodiment, the sixth embodiment is a cross-sectional view.
As shown in the figure, it is conceivable that a large number of recesses 9 having a radius of curvature substantially the same as the average radius of curvature of each gravel stone 2 are formed on the upper surface of the mesh plate 1. By forming the recessed portion 9 in this way, each gravel stone 2 can be accommodated in the recessed portion 9, making it easier to flatten a large number of gravel stones 2 evenly on the mesh plate 1. This is also effective in preventing the gravel stones 2 from being moved by strong winds after they have been laid.

Effects of the invention This invention uses a gravel laying pine with a simple structure to prevent gravel stones from being buried in the soil over time, and eliminates the waste of having to replenish gravel stones. It has the basic effect of ensuring that gravel stones always remain beautiful,
In addition, it has the advantage of preventing weeds from growing, allowing plants to be planted as appropriate during or after laying in the garden, and being convenient for growing those plants. It is a great way to maintain your beauty. Furthermore, it also has the advantage of being detachable and easy to clean even after installation.
