DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation net with a vegetation base bag used for greening slopes and the like, and a method for producing the same.

[0002]

2. Description of the Related Art As a vegetation net used for revegetation of a slope or the like, there is one proposed in Japanese Patent Publication No. 57-55852. In this vegetation net, two nets are superposed and integrated, and at a predetermined interval, a storage part (pocket) is formed without integrating the two nets, and vegetation such as fertilizer is formed in the storage part. A bar-shaped bag containing the material is inserted.

[0003]

However, there is a problem that the operation of inserting the bar-shaped bag into the accommodation portion formed between the two nets requires a lot of time and labor.
Specifically, when putting a bar-shaped bag between the nets,
Since the tip of the bar-shaped bag is hooked on the thread of the net, it takes several tens of seconds just to attach one bag to the net. Therefore, as described in the above publication, 30 to 50
If you try to attach bags at centimeter intervals,
It takes a considerable amount of time just to attach the bag. Also,
Generally, the bag itself is made of paper or non-woven fabric,
There is a high risk of breakage during the insertion of the bag, and if the bag is torn, it must be withdrawn and another bag inserted. There is a risk that the vegetation material will flow out during transportation and lose commercial value later. Furthermore, if bags are made of thick paper to avoid damage to the rod-shaped bags, it may take a long time for the vegetation material to exert its soil improvement effect when constructed on site, or in the worst case Is not expected to work at all. Also, if the bag that has been caught in the middle of the insertion is forcibly pushed in, the net will loosen, thereby reducing the strength of the net and preventing the original erosion prevention effect from being obtained, or if the bag is bent in the middle, A situation occurs in which the effect of slowing down flowing water on the slope and the effect of promoting the growth of plants cannot be expected.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a vegetation base bag containing at least one of a fertilizer, a soil conditioner, and a superabsorbent resin. In a vegetation net with a vegetation base bag comprising a net holding the vegetation, the net is knitted by Russell knitting in which an insertion thread is entangled with a warp yarn chain-knitted, and the vegetation base bag is knitted by Russell knitting An object of the present invention is to provide a vegetation net with a vegetation base bag inserted and held between the warp and the insertion yarn.

[0005] For this purpose, the method for producing a vegetation net with a vegetation base bag according to the present invention comprises the steps of: (a) arranging a warp and an insertion yarn from a plurality of warp guides and a plurality of insertion yarn guides arranged above the needles; Supplying, forming knitting nets by connecting adjacent knitting stitches with insertion yarns while forming knitting stitches in parallel in the vertical direction with a plurality of warp yarns; (b) after the above step (a), (C) during the step (b), inserting a vegetation base bag containing at least one of a fertilizer, a soil improvement material, and a superabsorbent resin;
(D) dropping and supplying the insertion yarn extending from the needle toward the insertion yarn guide to hold the vegetation base material bag on the net being knitted; and (d) after the step (c), the step (a). ) Is performed again.

[0006]

According to the vegetation net with the vegetation base bag and the method for manufacturing the vegetation base bag, the vegetation base bag is attached to the net during the production of the vegetation net by Russell knitting. Therefore,
This eliminates the need to insert the vegetation base bag after the net is manufactured, unlike conventional nets with a vegetation base bag, greatly reducing manufacturing costs and preventing damage to the vegetation base bag. We can provide quality products. In addition, since the vegetation base bag is securely held on the warp by the inserted yarn and these yarns do not loosen, both the vegetation base bag and the net exhibit the original erosion prevention effect and plant growth promotion effect. it can.

FIG. 1 is a partial plan view of a vegetation net 1 with a vegetation base bag according to the present invention, and FIG. 2 is a II-I of FIG.
It is an I line sectional view. In these figures, the vegetation net 1
The main body net 2 is formed by Russell knitting. This Russell knitting is a well-known technique and generally includes a plurality of warp yarns 3.
The knitting method of connecting adjacent chain stitches 4 with the insertion yarn 5 while continuously knitting the chain stitches 4 in parallel, has been widely used for products requiring decorative elements such as curtain fabrics. ing. In the present invention, using the Russell knitting, the chain knitting 4 is connected by the insertion yarn 5 while the chain knitting 4 is continued in the knitting direction (the direction of the arrow a) by the warp yarn 3 knitting the main body net 2. . Further, the insertion yarn 5 is released from being entangled with the warp yarn 3 at a predetermined interval (for example, 50 cm), and a bar-shaped vegetation base material bag 6 is held between the warp yarn 3 and the insertion yarn 5. . This vegetation base bag 6
A fertilizer 8, a soil improving material 9, and a superabsorbent resin 10 are sealed in a cylindrical bag 7 having a length substantially equal to the width of the main body net 2 and made of paper or nonwoven fabric. The vegetation base bag 6 contains a fertilizer 8, a soil conditioner 9, and a superabsorbent resin 10.
Does not need to be accommodated, and what accommodates may be selected according to the purpose, or other vegetation material may be accommodated.

An apparatus for manufacturing the vegetation net 1 will be described. 3 to 7, reference numeral 11 denotes the entire single raschel knitting machine. The Russell knitting machine 11 includes a large number of needles 13 arranged at predetermined intervals in the front and back directions of the drawing, and these needles 13 can reciprocate in the longitudinal direction (the direction of arrow b) as a whole. Has become. Above the needles 13, a warp guide 14 for supplying the warp 3 to each needle 13
And an insertion thread guide 15 for supplying the insertion thread 5 are provided so as to reciprocate in the front and back directions in the drawing. The operation of the needle 13 and the guides 14 and 15 has been well known in the Russell knitting industry, and a detailed description thereof will be omitted.
