Abstract

PURPOSE:To permit soil and seeds to be introduced into frames easily by spraying a vegetative base onto a slope in a framed form. CONSTITUTION:A net material 1 is laid on a slope 4, and a mixture of soil A, organics A', soil improving agent C, humectant D, and fertilizer B, together with seeds, is sprayed onto the net material 1 in a framed form. Soil and seeds F in the surrounding area of construction site can penetrate into frames easily by natural dropping, etc., and fix to the slope different from the conventional manner of whole surface spraying. The occurrence of run-off of the soil and seeds F and damage to plants in germ in the frames 3 can thus be avoided.

Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a frame-shaped slope greening method in which a frame-shaped body is formed on a slope and native seeds etc. from around the construction site are naturally introduced. be.

(b) Conventional technology The conventional method for greening slopes of roads, etc. is as shown in FIG.
Mix organic material A', fertilizer B1 soil conditioner C1 water retention agent D) and seeds E, and spray at a constant thickness of 1α to 10 crrL.
Degree) 1r: Secured and constructed on the entire surface of the slope. Currently, the surface construction method is the mainstream.

(c) Problems that the invention attempts to solve The conventional construction method has the following drawbacks.

(a) The current construction method involves spraying vegetation materials and seeds (mixed sowing of wild herbs and grass seeds) over the entire surface of the slope, so grass seeds that germinate and grow well (Kentara Key 31F Ruth Top, Clover), etc.
etc.), sown wildflower seeds do not germinate or grow.

(b) Since it is not possible to secure the required amount in a timely manner depending on the construction period, area, and construction period when collecting local seeds and wild plant water seeds around the construction site, it is necessary to secure and use the annual required amount at a specific site. There is. As a result, due to different climates, it is a short-lived grass, and because it does not germinate and grow, sown seeds cannot be seen growing on slopes during inspections, causing problems.

(c) If the grass seeds are sown over the entire surface of the slope and grow vigorously, if the slope is covered with grass seeds, the local seeds around the site will not be able to settle on the slope and will not germinate.

As mentioned above, this was invented in order to eliminate the drawback that conventionally local species around the site could not be introduced.

2) Means for solving the problem The present invention involves stretching a net-like body such as a wire net on the slope, and then extracting soil, organic materials, soil conditioners, water retention agents, fertilizers, etc., and seeds in necessary amounts from this net-like body. This is a frame-shaped slope greening method characterized by mixing and spraying the mixture onto a frame-shaped body.

To carry out the present invention, it is necessary to apply 4 to 5
Stretch the cTL eye metal mesh over the entire surface, and attach a lath pin (diameter 9 to 10 mm, length 20 to 30
I fix the soil, organic material, soil conditioner, etc. in a grid pattern.
A mark is placed on the area where the water retaining agent, fertilizer, etc. and seeds are to be sprayed, and the above-mentioned vegetation material is sprayed to form a frame-shaped body.This will be explained in more detail with reference to drawings and examples.

(a) If there is levitation, earth excavation, miscellaneous trees, etc. on slope 4, shape it.

(b) A wire mesh 1 with a mesh size of 4 to 5 degrees is stretched over the entire surface of the slope 4, and a lath pin (diameter 9 to 1
0, length 20-30) Fixed at 2.

(e) Mark the part of the frame-shaped body 6 where the vegetation material is to be sprayed.

(dl) Spray a mixture of soil A, organic material, soil conditioner C, water retention agent D, fertilizer B, etc., and seeds E onto the marked area above in a semi-cylindrical shape using the sound of a power spray machine. Slope adhesive part) Approximately 20~30Crn, thickness 5~
15 Frame-like body of sieve 6 Gold center spacing (distance from center to center of marks) fc Although it varies depending on the site conditions, in the case of a square section/division, the entire frame-like body 6 of about 50 to 100 crrt is formed.

This frame-like body 6 can be formed into a square, rectangle, rhombus, triangle, circle, semicircle, or other various shapes depending on the slope length of the slope 4 and various demands.

(e) After forming the frame-like body 6, in the case of the rainy season, spray milk or a rust-based emulsion or the like is applied to prevent the sprayed frame-like body 6 from being washed away by heavy rain or the like. Similar auxiliary work will also be carried out during the winter.

(E) Function As described above, the present invention provides a method for applying soil, organic materials, soil conditioners, water retention agents, fertilizers, etc., and seeds in required amounts from above the net after placing a mesh such as wire mesh on the slope. Because this method involves spraying onto a mixed frame, compared to the conventional spraying method (see Figure 4), local seeds from around the site naturally fall into the frame.
They easily invade the slopes as shown in Figure 3 F by wind, rainwater, and animals, and settle on the slopes. It germinates without being washed away and grows without being pressured by vegetation that has sprouted and grown from the frame. This realizes reliable slope greening from the viewpoint of nature conservation or the natural environment.

Claims (1)

[Claims] A feature of this method is that after a net-like body such as a wire net is stretched over the slope, the required amount of soil, organic material, soil conditioner, water retention agent, fertilizer, etc. and seeds are mixed onto the net-like body and sprayed onto the frame-like body. A frame-shaped slope greening method.
