DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a slope greening bag as a slope vegetation sheet used for greening slopes such as roads, rivers and parks.

[0002]

2. Description of the Related Art Conventionally, stabilization and revegetation of slopes have been achieved by planting plants such as turf on a sloped slope, and the vegetation method is to directly block turf on slopes. Generally, the method of pasting or seeding is mixed with fertilizer or soil and sown. However, in the case of soils whose slopes are liable to collapse, turf blocks and seeds are often washed away due to rainfall, and it is difficult to ensure stable and stable vegetation. On the other hand, on a slope that contains a large amount of rock or rock, it takes a long time for stable vegetation, and it is difficult to plant greenery because the soil material easily collapses. Therefore, studies have been conducted on methods of partially embedding concrete frames, etc., to prevent the slope and the soil material from collapsing, and by using a net-like material on the slope to prevent the soil from sliding down, and materials for that purpose. Is
(For example, Japanese Patent Publication No. 60-35490, Japanese Patent Application Laid-Open No. 62-23336,
-72947).

[0003] Although these construction methods are effective for stable curing of turf, most of them have a problem that the work requires time and labor. Therefore, slope vegetation can be easily constructed regardless of slope slope and soil quality, and has the purpose of providing an effective one for stable vegetation. Greening bags are being considered.

[0004]

In the manufacture of such a slope greening bag, when the bag is large, the ground cloth and the coated net-like material on the front side constituting the bag are formed. In addition, it is difficult to sew accurately when sewing together, it is inefficient, and there is a problem that a large work space is required.

[0005]

SUMMARY OF THE INVENTION The present invention comprises a woven fabric 1 on a slope side, a net-like material 2 on a front side, and a reinforcing belt 9, and the net-like material 2 is partially formed on the woven fabric 1. And the periphery is sewn and integrated with the reinforcing belt 9, and a plurality of joint portions 12 of the parallel woven fabric 1 and the net-like material are formed at a predetermined interval from the edge to form a customer soil material storage portion. in sewed of slope greening bag body made as 13, of the fabric 1 or a net-like material 2 forming
It is characterized in that a mating mark portion 8 serving as a mark in the mating portion 12 is formed by driving (weaving, knitting) of a color thread and sewing.

Here, the members constituting the slope greening bag will be described. The woven fabric 1 is located on the side in contact with the slope when the bag is applied to the slope, and is not particularly limited as a material, such as natural fiber, synthetic fiber, regenerated fiber, and a mixed fiber thereof. In terms of construction efficiency on slopes, the width is usually 1m
In many cases, the length is about 3 m or more, and the length is about 5 m or more and about 20 m. Synthetic fibers, particularly drawn flat yarns, are suitably used because they require high strength and durability, and are suitable for rooting vegetation plants. Woven density is selected.

The net-like material 2 is located on the upper side when the bag body is constructed on the slope, and is preferably made of synthetic fiber as in the case of the above-mentioned woven fabric 1, and is more suitable for germination and growth of vegetation plants. Stretched monofilaments are suitably used in consideration of the yield of the soil material without any hindrance, and are net-like materials such as plain weave, entangled weave, and Russell knit.

[0008] A structural feature of this bag for greening a slope is that the upper net-like material is partially sewn to the lower woven fabric with a slack so that the soil material has an appropriate thickness. The lower woven fabric keeps a substantially flat surface and does not have an uneven surface even when the guest soil material is filled. It is a structure that does not become small and the plant can be quickly settled on the slope.

A characteristic of the manufacturing method of the present invention is that the woven fabric 1 and the net-like material 2 as basic members are joined peripherally and partially to form a bag. For example, a material obtained by heat welding or a natural fiber by an adhesive may be selected, but a method of sewing by strong sewing is most preferable.

As a means for forming a matching mark portion 8 serving as a mark at the joint portion of the woven fabric 1 or the net-like material 2 by driving a color yarn, a color yarn is formed at a predetermined interval by a general multiloom in a loom. The display portion can be formed by changing the pattern of the knitting structure by partial skipping or the like in the knitting machine.

[0011]

The difficulty in the manufacturing process is that it is necessary to put a mark on the sewing portion such as the joint portion at the intermediate portion before overlapping the woven fabric 1 and the net-like material 2 cut to the respective sizes. Since the body is large, it takes time to measure and display the distance from the peripheral edge each time, and it is problematic in that it is difficult to secure a work space. Therefore, when knitting and weaving the woven fabric 1 and the net-like material 2, the colored yarn or the like is partially inserted into the warp and the weft so as to be a mark at the time of sewing as a mark portion 8. Efficiency increases.

[0012]

The present invention will be described below in detail with reference to examples. FIG. 1 is an enlarged plan view showing a part of a woven fabric 1 for a base cloth. This woven fabric was prepared as follows. First, using polypropylene (MI = 1.1, melting point 150 ° C) as a thermoplastic synthetic resin, extruded from a circular die at a melting temperature of 280 ° C, cooled to form a film, a stretching temperature of 145 ° C, and an annealing temperature of 1 ° C.
A flat yarn having a fineness of 1,350 denier was obtained by hot plate contact stretching at 50 ° C. and a stretching ratio of 5.5. Using this flat yarn as warp yarn, when producing a woven fabric with a weaving density of 13 × 13 yarns / inch and a width of 1,090 mm using a multicolor machine, 200 mm from each end edge
The color yarn 3 is inserted into the center three warp yarns and the color yarn 4 is inserted at 160 mm intervals between the weft yarns, cut into a width of 1,090 mm, and a length of 9,780.
The woven fabric 1 was used for a base fabric of mm.

FIG. 2 is an enlarged plan view showing a part of the net 2 used on the front side. This net-like object 2 was created as follows. First, high-density polyethylene (MI = 1.0, melting point 129 ° C) was used as the thermoplastic synthetic resin, and the melting temperature was 2
After being extruded from a nozzle at 70 ° C. and cooled, it was drawn in a hot water bath at a draw ratio of 7.8 to obtain a monofilament having a fineness of 380 denier. Using the monofilament, the pitch of the ground yarn 5 is set to 9 yarns / inch and the density is 5 chains / cm with a Russell knitting machine.
When manufacturing the net-like material 2 of 300mm from each end edge
And a colored yarn 7 for the pattern yarns 6 at the three central positions.
Is a 4/9 inch swing every 260 mm,
And a matching mark when sewing. Cut this, width 1,
The net-like material 2 was 290 mm long and 15,480 mm long.

FIG. 3 is a plan view of a slope greening bag made by the manufacturing method of the present invention. This baggage for slope greening comprises a woven fabric 1 on the slope side, a net-like material 2 on the front side, and a reinforcing belt 9, and the net-like material 2 has a partially folded portion with respect to the woven fabric 1. The periphery is sewn and integrated together with the reinforcing belt 9, and a plurality of joint portions 12 of the parallel woven fabric and the net-like material are formed at a plurality of locations while leaving a predetermined distance from the edge to form a guest soil material accommodation portion 13. In this slope greening bag, the woven fabric 1 and the net-like material 2 are superimposed, and the woven fabric is sewn to a length of 690 mm in the central portion excluding 200 mm from both ends of the woven fabric and 300 mm from both ends of the net-like material 2. The cloth 1 was arranged at intervals of 160 mm in the length direction, and the net-like material 2 was sewn together at matching mark portions 8 indicated by colored threads at intervals of 260 mm in the length direction.

[0015] A belt 9 (50 mm width) for reinforcement is used for the peripheral connection.
However, since the net-like object 2 has an extra length, the net-like object 2 was folded and sewn and joined near the center of the joint. In addition, the reinforcing belt 9 used at the edge in the length direction is projected from both corners by approximately 2,000 mm, and can be used for mounting and fixing.

The bag thus manufactured according to the present embodiment was laid on a slope, and anchors were fixed at several places from above the reinforcing belt. From the inlet 10 opened in the upper corner of the bag body, visitor material 11 in which seeds, fertilizer, soil modifier, etc. are mixed in advance.
Was forced into the bag body from the extruder and was filled up to the lower part, so that the bag body had a shape having many ridges as shown in FIG. About two months after the application, the seeds germinated and became a beautiful green slope.
