Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a mat comprising two perforated sheets with a plurality of compartment bags, which is spread and fixed on a slope surface, and furthermore, the mat is This invention relates to a slope protection pine that protects the slope along with the vegetation by filling the compartment bag with soil and seeds.

(Prior Art) Conventional slope protection methods include spraying seeds, covering with netting, or covering with straw.

However, with these methods, the slope is often washed away by heavy rain, or even if vegetation is grown in cold regions, the vegetation is lifted up by frost heave and collapses.

Another method is to build a frame with glue to create a retaining effect and then grow vegetation within it, but even this method has drawbacks such as the frame often collapses when frost heave occurs, and construction costs increase. Other methods are also known, such as stretching a net and spraying granular soil mixed with adhesive and seeds over the net, or forcing slurry into a water-permeable bag using a mixing device or a press-in device. However, this method also has problems such as increased equipment costs and transportation costs.

(Problems to be Solved by the Invention) The present invention was developed in order to solve the conventional problems, and provides an inexpensive pine tree that reliably prevents the topsoil from collapsing on the slope and is capable of greening vegetation. It is intended for this purpose.

(Means for Solving the Problems) The present invention forms a mesh-like porous sheet 1a having a size that allows the roots 6 for vegetation to penetrate into a rectangular shape with a predetermined width. having the same width as the porous sheet 1a on one side of the porous sheet 1a,
A similar mesh-like porous sheet 1b is polymerized so as to cover the entire surface of the sheet 1a, and a rectangular porous sheet 1a is formed by polymerizing both.
1b are stitched together in a biased manner with a plurality of stitched portions 1d, 1d, and other biased stitched portions 1d, 1 intersect with the biased stitched portions 1d.
d... to form a rhombic lattice-like stitched portion 1d, and the diamond-lattice shape sectioned by the stitched portion 1d and the two perforated sheets 1a, 1b... are used to form compartmented bags 7, 7... A plurality of notches 1c, 1c for storing earth and sand are formed on the porous sheet 1b side of each compartment bag 7.
... is formed with a notch, and each notch opening 1c is,
They are placed in a staggered manner on one surface of the porous sheet 1b.

(Function) Filling the notches of pine trees laid on the slope with earth and sand and spraying seeds onto the pine trees will green the entire surface of the pine tree, and prevent the topsoil of the slope surface from collapsing, especially at the seams. Since the section has a rhombic lattice shape, the surface drainage flows in a staggered manner through the seamed sections, which reduces the water force and prevents the risk of washing away the topsoil, effectively protecting the slope.

(Example) An example of the present invention will be described below with reference to the drawings. Fig. 1 is a perspective view of a pine according to the present invention, and 1a in the figure is a net-like perforated sheet made of synthetic resin. This porous sheet 1a is formed into a rectangular shape with a predetermined width, and is formed into a mesh shape that allows the roots 6 of the plants to penetrate.

1b is a porous sheet similar to the porous sheet 1a, and this porous sheet 1b is polymerized so as to cover the entire porous sheet 1a. Reference numeral 1d denotes a seam portion in which the two perforated sheets 1a and 1b are sewn together in a rhombic lattice shape.

In FIG. 1, the rectangular porous sheets 1a, 1b are joined together at a plurality of sewn parts 1d, 1d...
Then, the bias-shaped stitched portions 1d are sewn together using other bias-shaped stitched portions 1d, 1d, .

Reference numeral 7 denotes a plurality of compartment bags formed of the above-mentioned perforated sheets 1a and 1b and having a rhombic lattice shape divided by stitched portions 1d. It is set up in a meandering manner.
1c is a notch formed approximately in the center of the perforated sheet 1b of the compartment bag 7 having a rhombic grid shape;
This notch 1c is formed for each compartment bag 7, and is formed in parallel along the width direction of the perforated sheet 1b, but adjacent notches 1c in the length direction of the perforated sheet 1b are , are staggered from each other.

Furthermore, the stitching means for the stitching portion 1d described above may be used to knit the porous sheets simultaneously at the time of knitting, or to knit both porous sheets together using a means such as a sewing machine.

It will be even more effective if seeds and fertilizers are attached to the pine in this example in advance.

Next, the operation of the above embodiment will be explained.

As shown in Fig. 2, the pine shown in Fig. 1 is
An appropriate number of mats are laid on a pre-prepared slope 3, and then they are fixed with retaining materials such as stakes 2, if necessary, so that the mats do not shift. Thereafter, earth and sand is placed on the mat, and an appropriate amount of earth and sand is filled into the compartment bag 7 through each notch 1c while being evenly leveled with a damp cloth or the like. If the seeds are sprayed from above the pine, the seeds will eventually germinate, and the roots 6 will penetrate not only the inside of the soil of the compartment bag 7 but also the porous sheet 1a, and the roots 6 will spread and take root in the ground. This makes it possible to green the entire surface of the pine tree, while also reliably protecting the slope.

In addition, since the surface drainage of the slope flows in a meandering manner in a staggered manner along the seams 1d provided in a rhombic grid shape, the water force is moderated compared to flowing in a straight line along the slope. There is no risk of topsoil flowing away.

(Effects of the Invention) From the above, the present invention has the following excellent effects.

(1) Since the seam is formed in a rhombic lattice shape, the surface drainage water on the slope flows down in a staggered manner along the perforated sheet, so the water force is extremely moderated. Flows and topsoil do not collapse, the slope is reliably protected, and vegetation functions are also promoted.

(2) Since a large number of compartment bags are provided on the entire surface of the porous sheet, the entire surface of the pine is greened, making it possible to provide a pine that does not exist in the past.

(3) Since the soil on the surface of the pine is confined inside each compartment bag, it will not be washed away by rainwater, and there is no risk of it collapsing due to frost heaving, etc. teeth,
Since it is an assembly of a large number of compartment bags, there is no need for a mixing device or a press-in device for mixing water during construction as in the past, and it is possible to provide a slope protection mat that can be mass-produced at low cost.
