JPS60246925A - Vegetating method for face of slope - Google Patents

Abstract

PURPOSE:To protect a face of slope, by a method wherein, after a net body, which has a lateral-striped pattern formed by alternately repeating large and small meshes at intervals, is spread over a face of slope, bag bodies containing vegetation materials are anchored and firmly adhered to the face of slope. CONSTITUTION:Meshes of a net body 1 are formed such that a small mesh part 2 and a large mesh part 3 are alternately repated to form a lateral-striped pattern. A bag body, having air and water permeability, is filled with seeds, fertilizer, a water retension material, a soil improving material, etc. to form a bag body 5. After the bag bodies 5 are arranged at specified distances on the net body 1, anchors and lock nails 6 are driven through both the bag body and the net body to anchor and firmly adhere the net body 1 and the bag bodies 5 to a face of slope. This, since the lateral-striped patterns are formed in the net body 1 at specified distances, enables simple installation of the bag bodies 5 to the net body 1 without using a measure.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a slope vegetation construction method for preventing coffin materials from being washed away and moved.

(Prior Art) Conventionally, in the slope vegetation construction method, as a method of preventing the collapse of soil on the slope surface, a method of stretching a net on the slope surface has been widely practiced and has been highly effective. In addition, the seed spraying method has been widely adopted as a greening method on slopes, but in terms of preventing the seed-sprayed base material from collapsing, it is difficult to prevent the seed-sprayed base material from collapsing except on embankment slopes with gentle slopes, especially on cut-off slopes. It is very effective to install nets to increase the establishment of seedlings, and seed spraying methods that use nets are used in most of the greening methods for cut slopes.

However, even with the nets that are used in large quantities, especially those woven from chemical or vegetable fibers, they cannot be anchored using anchors, pegs, or other anchoring devices during tensioning. In cases where the anchoring part is torn, the p-net and the anchoring device tend to come off easily, and the anchoring part, which is the only point of contact between the slope and the netting, does not come together, which is considered to be a problem. .

The fact that the slope and the net are not integrated means that the net has a poor effect on preventing the sand on the slope from collapsing, and at the same time, when the yuzu spraying method is applied, the seed spraying base material is likely to be washed away. This improvement was desired.

In view of the shortcomings of the conventional nets, and as a result of various researches, the present inventors have developed a net structure that is made denser and stronger at the part where the net is anchored on the slope using an anchoring tool. Gansho 57
- Proposed in No. 199233. Subsequently, further research revealed that if this net was used in combination with a bag containing vegetation material that directly or indirectly has a beneficial effect on plant growth, it would be possible to grow vegetation more reliably or over a longer period of time. In addition, since this net exhibits a horizontal striped pattern at regular intervals, it is possible to attach bags at regular intervals without having to measure each time. Therefore, we arrived at the present invention because it is extremely convenient.

The present invention will be explained in detail below.

(Structure of the present invention) That is, the present invention involves repeatedly making a mesh thinner and denser at appropriate intervals on a slope, developing a mesh body forming a horizontal striped pattern, and then directly or indirectly exerting a beneficial effect on the growth of plants. Vegetation construction method, characterized in that bags having air permeability and water permeability are placed at appropriate intervals and anchored to the slope surface using anchoring tools so as to be integrated with the net body A. It is.

To explain the present invention in more detail with reference to examples, the material constituting the net body (1) used in the present invention can be any material such as chemical, vegetable, or metallic.
Monofilament made from chemical polyester, etc., or thread called flat yarn is the cheapest and most suitable.

This material is usually knitted using the raschel knitting method so that the stitches are repeated densely and sparsely at appropriate intervals. Arrange the weft threads of
The s minute (3) is a normal eyelet (about 1r to 2Qmm).

Pi-jin is 25~! ; The width of the mesh body (1) is 7.0-2.0 m, the length is about 100 m, and reinforcing lobes are arranged at both ends and the center.

Next, the bag (5) used in the present invention will be explained.

The material of the bag σ) used in the present invention is made of air permeable and water-permeable materials such as paper, cloth, and warped cloth, and the vegetation sides that accommodate the bag σ)K are citrons, fertilizers, water retention materials, and soil improvement materials. Use one type or a combination of two or more types.

For example, when storing seeds etc. in the bag body (5) and using it as a vegetation base when constructing the slope (30)K, the material of the bag body (σ) should be paper or cloth that allows vegetation to pass through. In addition to seeds, vegetation materials include fertilizers, water retention materials, and soil improvement materials.

In addition, when the bag body (5) is mainly used as a fertilizer base, the bag body (5) should be made of non-woven fabric or warped cloth that has some degree of strength, and (11) the raw material should be mainly slow-release fertilizer. do.

The size of the bag body (5) is usually about φ2 to 5 cm, and the length is set to an appropriate length during construction.

To carry out the present invention using the above-mentioned materials, the horizontally striped net (C) described above is temporarily deployed on a slope (30), and then
The bags (5) described above are arranged on the net (1) at regular intervals, and anchors, pegs 2), etc. are used to connect the bags (5) and the net (1) so that they are integrated. The net body (1) and the bag body (J) are driven into the slope so that they are anchored and tightly attached to the slope. When anchoring only the net, use anchoring tools in the denser parts of the net so that it becomes one with the slope.

The anchoring interval of the bag is 23amr%Qcm, etc., depending on the slope (3D
) is selected depending on the situation, and is usually anchored by overlapping the part of the mesh (1) where the eyelets are dense.

After carrying out the construction method of the present invention described above, seeds will normally be produced. Since this is a slope vegetation construction method in which the housed bag and the net are anchored together on the slope, the net may be torn by the anchoring tool, or the anchoring tool may cause the net to break, unlike in conventional net tensioning methods. This prevents the bag from falling off the body, and since the mesh exhibits a horizontal striped pattern at regular intervals, it is possible to attach the bag at regular intervals without having to measure each time. Therefore, it can be constructed extremely quickly.

In addition, the net can be firmly integrated with the slope in the dense part of the net or in the part of the net anchored together with the bag, which prevents landslides and washing away on the slope.Additionally, the seed spraying method can also be used. In this case, the sprayed vegetation material can be prevented from being washed away.

In particular, if the bag body and the net body are anchored by overlapping the dense parts, it is possible to completely block the collapse and movement of earth and sand, and the washing away.

Furthermore, if seeds or other vegetation materials are used in the bag, vegetation will germinate and grow preferentially from this bag part, and this part will serve as a base for vegetation, making it possible to reliably green the bag.

In addition, when the bag mainly contains slow-release fertilizer, it becomes possible to sustain the vegetation introduced by seed spraying or other means for a long period of time, and the protection of the slope by vegetation can be maintained for a long period of time.
