Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for greening a hard, hemorrhoid-prone slope.

Recently, it has become necessary to green even hard slopes, which were traditionally sprayed with mortar, and various types of greening work are being carried out in combination with structures, but these are extremely expensive.

Hard slopes are always steep and unsightly, and problems with such slopes are the erosion of the base layer of vegetation, drying, and the outflow of fertilizer nutrients. It is said that about 80% of the fertilizer applied to slopes flows down to the bottom of the slope, and the decline of vegetation due to lack of fertilizer occurs after construction.
It happened in 2 years.

At such sites, it would be possible to recover by managing fertilizers, but isn't it actually done from an economical point of view? This is the current situation.

The present invention provides a method for sustaining greening for a long period of time even on slopes with steep slopes and poor conditions by supplying fertilizer nutrients over a long period of time from the initial stage. After much consideration, we arrived at the present invention.

The configuration of the present invention will be explained below.

The most important thing in the construction method of the present invention is the fertilizer tube.

Although various materials are conceivable for constructing the fertilizer tube of the present invention, as a result of examining the three points of strength, flexibility, and breathability, nonwoven fabric was found to be the most suitable material, and nonwoven fabric was selected.

This non-woven fabric must also have the strength to not tear even when it is made into a bag to contain fertilizer and tied to a net with wire, etc., and has the flexibility to respond quickly to the unevenness of the slope. ,
The most important thing is to select a nonwoven fabric that does not have an excessive amount of fertilizer nutrients that will be washed away, but has enough ventilation to allow the nutrients to be removed and removed over a long period of time.

Considering the above points, among nonwoven fabrics, thickness 0.1 to 3. lol
1 tensile strength vertical 10-25kg/5cIrL1 horizontal 10
~30kg/5cIrL, ventilation volume 10~30
A nonwoven fabric with a velocity of 0 cc/cm/sec was selected.

(In the following description, the nonwoven fabric simply refers to the above-mentioned nonwoven fabric.) This nonwoven fabric is sewn to form a bag body, and fertilizer is stored in the bag body to form the fertilizer cylinder 1.

The fertilizer stored in the cylinder can be a fast-release fertilizer that has a fertilizing effect immediately after construction (e.g. general compound chemical), or a slow-release fertilizer that has a fertilizing effect about 6 months after construction (e.g. IB Chitsuso, CD
U), 1 or 2 years after construction, mix and use effective fertilizer (for example, resin-coated fertilizer).

A slow-release fertilizer is a mixture of polyolefin resin and a soaking agent, and the timing of the fertilizer's effectiveness is usually adjusted by adjusting the amount of the water soaking agent.

In addition to fertilizer, vermiculite is used as a water-retaining material, bentonite or lime is sometimes used as a soil conditioner, and in this case, it is used according to the site conditions surveyed in advance.

The shape of the fertilizer cylinder is usually φ3 (1'771 and length 100cI)
fL, but is not limited to this.

Further, when manufacturing fertilizer cylinders, a hook 3 is often attached as a metal fitting as shown in FIG. 5 to improve workability when attaching the fertilizer cylinder to a net-like body.

Next, to explain the construction method, a wire mesh 2 is stretched over the slope 30, and hooks or hooks are attached to the wire mesh with fertilizer tubes arranged at appropriate intervals in a contour line as shown in FIG. 1 or in a plover shape as shown in FIG. Attach with a ring or wire ○ It is also necessary to secure the attached fertilizer cylinder with anchor pins 4 or nails so that it conforms well to the unevenness of the slope.

(Figure 4 is a partially enlarged view showing the state in which the fertilizer cylinder is attached to the wire mesh.) Also, centering on the anchor driving part of the wire mesh stretched on the slope, or the part where the wire mesh floats in the recessed part of the slope. By spraying mortar in dots 5 using a mortar spraying machine at appropriate locations, the earth and the wire mesh will be integrated, the slope will be in a stable state, and then the fertilizer tube will be attached to the wire mesh as described above.

Once the above work is completed, use a mortar sprayer, minicrete pump, etc. to mix seeds, fertilizer, organic fibers, organic compost, a small amount of cement, and sometimes sand and soil to form a sprayed vegetation base layer. .

In this case, it is desirable to spray the fertilizer at a thickness that does not completely cover the attached fertilizer tube, and by doing so, the protruding fertilizer tube will disperse rainwater during rainfall and prevent erosion.

If an asphalt emulsion or vinyl acetate emulsion is sprayed on top of this, the surface of the sprayed vegetation base layer will be more stable, and seed efficiency will be improved.

As described above, the construction method of the present invention has a tube made of a nonwoven fabric that is strong enough to not break even with a slight physical impact, flexible enough to respond to unevenness on the slope, and has an aeration rate that allows fertilizer nutrients to be gradually eluted. Three types of fertilizers (fast-release, slow-release, and slow-release), soil conditioners, and water retention materials are put into the tube to form a fertilizer tube, and the fertilizer tube is placed on a mesh structure stretched over the slope with mortar placed at appropriate locations. The construction is very simple, as the vegetation base material is sprayed after the cylindrical body is installed. This prevents the loss of lumber.

As mentioned above, fertilizer nutrients can be supplied to plants over a long period of time depending on the type of tube and fertilizer, and the fertilizer tube contains not only fertilizer but also soil improvement materials and water retention materials that match the site conditions. As a result, soil conditions have improved,
Plants can continue to grow vigorously even on steep slopes where fertilizer nutrients have been washed away and plants have declined in a short period of time.
