[0001]

[Industrial applications]

 The present invention relates to a vegetation cover suitable for use in vegetating grass or wood on an inclined surface such as a slope.

[0002]

[Prior art]

 Conventionally, plants such as grass and wood (hereinafter referred to as “vegetation”) are vegetated on slopes such as slopes (hereinafter referred to as “slopes”) in order to prevent soil loss and to promote greening. As a means for achieving this, it is widely known that seeds and fertilizers are bonded to the lower surface of the straw with an adhesive. In addition, a vegetation net (Japanese Patent Application Laid-Open No. 55-68927), which is provided with a vegetation material accommodating portion in the net, in order to prevent soil and sand and actively grow vegetation, and slopes. The turf grass for preventing landslides, in which seeds and fertilizer are attached to the net, which has horizontal stripes formed by repeatedly sparsely and densely forming the mesh of the turf so that it is firmly integrated with the turf grass. 7962), a double part is formed by a specific method on a net woven by entanglement weaving using tape-like wefts to prevent slope erosion and is useful for slope protection and greening. The vegetation net (Japanese Patent Application Laid-Open No. 3-113040), the net constituting the covering material is composed of a pulp and a vegetation sheet made from a paper made of a plant organic soil improving material, so that the slope is covered only with the covering material. Vegetation covering material (Jitsuhei 2-26995) Publication) are known.

Further, as devised by the applicant of the present invention, it consists of a net-like vegetation bag 2 in which a vegetation base material bag 3 is housed, and a wire netting 1 attached to the vegetation base material bag 3, which is extremely easy to construct, is inexpensive and shortens the construction period. There is a wire mesh netted vegetation bag that can be made (Jikkou 6-12042).

[0004]

[Problems to be solved by the device]

 Each of the above-mentioned conventional technologies has an effect equivalent to the greening of the slope, but conventional vegetation sheets, vegetation covering materials, vegetation bags, etc. (hereinafter referred to as vegetation sheets, etc.) corrode the entire sheet member. Since it is formed of only a corrosive material or is formed of only a non-corrosive material, there are the following problems. First, vegetation organisms that vegetate on slopes using this type of vegetation sheet etc. differ in the time required for rooting and fixing on slopes depending on the type, and they are divided such as Hermanus and Narcissus. There are also bulbs and strains, and their growth processes are different. For this reason, when using a vegetation sheet, etc., where the entire sheet member is corrosive, the vegetation sheet etc. will begin to corrode before the roots settle on the slope, and the vegetation will only retain the roots. However, there is a problem that vegetation is washed away because it cannot withstand rainwater, freezing, snowmelt water, and falling earth and sand. Further, since the corrosive sheet member deteriorates with time, there is a problem that strength for protecting vegetation against avalanche, frost heaving, freezing, heavy rain, etc. is gradually lost.

On the contrary, in the case of plant organisms in which roots, stems, etc. are divided, if the entire sheet member is non-corrosive, there is a problem that normal division cannot be achieved because these divisions are hindered. .

Further, the conventional technique has the following other problems. That is, since the slope is not a perfect flat surface but is uneven, if the construction to fix it on the slope is not enough or if the frost heave phenomenon occurs on the slope, the vegetation base material is stored. Parts, tapes, nets, etc. may rise off the slope. In such a case, water cannot be replenished because the vegetation base material cannot settle on the slope, seeds will dry, and vegetation will grow unevenly on the slope. As a result, there is a problem that they do not meet the growth standards, and they also have a problem that they look bad and soil and sand cannot be fully established. However, since there was no consideration in the prior art in preventing the occurrence of vegetation unevenness due to the floating of seeds from the slope, seeds were sown or sprayed on the place where the seeds did not settle. The current situation is to spray seeds with a machine. However, since it is a work on an inclined surface and the surrounding areas of poor germination and poor growth are in a germinated state, it is necessary to work so as not to damage the vegetation that is growing smoothly. However, there is a problem that the workability is extremely poor, and the cost for such repair work increases.

The present invention has been made in view of the above-mentioned various drawbacks and problems of the prior art, and can protect plant life from avalanche, frost heavier, heavy rain, etc. and surely establish it on the slope, and further The object of the present invention is to provide a vegetation cover that does not hinder the growth and division of rice. In addition, by forming a pool of soil particles, seeds, water, etc. flowing down from above the slope, the vegetation base material can be firmly fixed on the slope and soil loss can be achieved. The object is to provide a vegetation cover that prevents Furthermore, even if the seed does not grow due to the unevenness of the slope, improper construction or frost heave phenomenon, the vegetation cover can set the seed evenly on the slope and vegetate life. The purpose is to provide.

[0008]

[Means for Solving the Problems]

 The means of the present invention, which is configured to solve the above-mentioned problems, includes an upper net portion formed of a non-corrosive and non-decomposable material and a lower net portion formed of a corrosive or degradable material. A sheet-shaped bag support formed by stacking or knitting into a bag and a vegetation base material filled in a tubular bag formed of a corrosive, degradable or water-soluble material, It is composed of a plurality of vegetation base material bags which are laterally arranged at a predetermined distance from each other.

And, a plurality of vegetation base material-complementing pouches formed from a corrosive, decomposable or water-soluble material into a pouch shape and filled with at least seeds and fertilizers inside the plaques. It may be located between the bags and disposed in the sheet-like support.

Furthermore, the sheet-like support may be covered on the outside with a net made of metal.

[0011]

[Action]

 The sheet-shaped support is configured as a bag by superposing or knitting the upper net part made of non-corrosive and non-degradable material and the lower net part made of corrosive or degradable material. Therefore, as the vegetation grows, the lower net part corrodes or dissolves, so that the growth and division of the vegetation are not hindered. Moreover, the lower net part has a water retaining effect, and can also have a fertilizing effect by corroding or dissolving. On the other hand, the upper net part made of non-corrosive and non-degradable material has strength over a long period of time and can protect vegetation organisms against avalanche, frost heave, freezing, heavy rain, etc. and ensure their establishment. .

[0012] Furthermore, a plurality of vegetation base material bags provided laterally on the sheet-shaped support form contour lines on the slope to collect seeds, soil particles, water, etc., so that the seeds can be firmly fixed. It Even if the vegetation base material bag is separated from the slope due to improper construction, frost heave phenomenon, or unevenness of the slope, seeds and fertilizer are supplied to the slope from the adjacent vegetation base material supplement sachet. In addition, the sheet-shaped support is made of a corrosive or degradable material, and the vegetation base material bag and the vegetation base material supplement sachet are made of a corrosive, degradable or water-soluble material, respectively. These materials corrode or dissolve as the organism grows.

The mesh body securely fixes the sheet-like support on the slope by interposing anchor pins and protects the snow from movement, melting, freezing, rainwater flowing down and the like.

Reference numeral 8 denotes a tubular bag that constitutes each vegetation base material bag 7. The tubular bag body 8 can accommodate the granular and powdery vegetation base material 9 described later without leaking, and after the seed 9A germinates. The buds are formed by using metal fibers, chemical fibers or plant fibers having corrosive, decomposable or water-soluble properties, which allow the shoots to grow to the outside without any trouble. Then, the fibers of such a material are woven into a fine mesh or a non-woven fabric, and the longitudinal ends thereof are closed by suitable closing means such as binding, sewing, adhesion, welding, etc. according to the properties of the fibers. It is possible to use those formed in the above. Further, as the tubular bag body 8, it is possible to use a tubular bag formed of a synthetic resin film which is decomposed by microorganisms, ultraviolet rays and the like.

Reference numeral 9 denotes a vegetation base material filled in the bag body 8. The vegetation base material 9 includes seed 9A, granular or powder fertilizer 9B, soil conditioner 9C, water retention agent 9D, and organic material 9E as appropriate. It consists of mixed quantities. Then, the vegetation base material bag 7 having the above-described configuration is inserted into each of the tubular accommodating portions 6 of the sheet-shaped support 2 so that the sheet-shaped support 2 is arranged in two columns in the longitudinal direction and It is installed at intervals.

Reference numerals 10, 10, ... Show a plurality of vegetation base material supplement sachets. Each vegetation base material supplement pouch 10 is formed by a sheet material made of the same material as that of the vegetation base material bag 7 described above into a bag body having a volume of about 1/10 of that of the tubular bag body 8. The pouch body 11 is composed of the pouch body 11 and the pouch body 11 filled with at least the seed 9A and the fertilizer 9B. Then, each vegetation base material supplement pouch 10 is placed between the vegetation base material bags 7, 7 spaced apart by a predetermined distance and mounted on the sheet-shaped support 2.

Reference numeral 12 denotes a wire net that entirely covers the upper side of the sheet-shaped support 2 having the above-mentioned configuration. As the wire net 12, a wire net woven in an appropriate shape such as a rectangular shape, a hexagonal shape or a rhombic shape as shown in the drawing is used, and the sheet-like support 2 is provided with a binding wire, a thread or the like for binding. It is bound at an appropriate position by using a means. By using the wire net 12 of this embodiment, a sheet-like support is provided in a place where the slope A is a steep slope of about 45 degrees or more, a place where a large amount of snowfall is likely to cause snow sliding, and a place where sediment is likely to fall. The body 2 can be securely fixed by the wire net 12 via anchor pins, etc., and the sheet-shaped support 2, the vegetation base material bag 7, the vegetation base material supplementation by external force such as movement of snow, rainwater, and sediment. It is possible to prevent the pouch 10 from being damaged. In addition, when more strength is required, for example, when the total weight of the vegetation base material bag 7 is large due to the large amount of the vegetation base material bag 9 being filled, the lower side of the sheet-shaped support 2 is It is better to cover with a wire net 12.

Thus, the vegetation cover 1 of the present embodiment is a sheet-like support 2 composed of an upper net portion 3 and a lower net portion 4, and is inserted into the sheet-like support body 2 so as to be separated from each other. The plurality of vegetation base material bags 7, 7, ... Mounted on the plurality of vegetation base material bags 7, 7, ... The vegetation base material-complementing pouches 10, 10, ... And the wire net 12 that entirely covers the upper side of the sheet-like support 2.

In this embodiment, the vegetation cover 1 is laid so that each vegetation base material bag 7 is laterally placed on the slope A, that is, in a contour line with respect to the slope A. The anchor 13 is attached to the periphery of the vegetation cover 1, and the raspin 14 is fixed to the inner side of the metal net 12 to drive the vegetation cover 1 to the ground. As a result, the vegetation cover 1 is fixed in a state in which it is in close contact with the slope A, is well adapted to the soil, and can be settled in a state that is good for seed growth. Further, since many vegetation base material bags 7, 7, ... Are arranged in a contour line with respect to the slope A, the soil, water, and vegetation base material 9 flowing down the slope A are blocked. Since these hangouts B are formed, even if the slope A has a steep slope, it is possible to prevent the vegetative base material 9 and the like from completely flowing down, and thus at least the contour lines. The vegetation can be fixed in a shape.

Since the lower net portion 4 constituting the sheet-shaped support 2 of this embodiment is formed of a corrosive or degradable material, the lower net portion 4 is corroded or dissolved as the plant life grows. As a result, the vegetation can grow and divide without being obstructed by the lower net portion 4. In addition, the lower net portion 4 has a water retaining effect due to the nature of the material, and can also have a fertilizing effect by being corroded or dissolved. On the other hand, the upper net part 3 is made of a non-corrosive and non-decomposable material, so even if the lower net part 4 is corroded or dissolved, vegetation can be reliably secured against avalanche, frost heave, freezing, heavy rain, etc. Can be protected.

Further, as described above, the vegetation base material 9 is a mixture of the fertilizer 9B, the water retention agent 9C, and the organic material 9D in addition to the seed 9A. Therefore, when the vegetation base material bag 7 is separated from the slope A, even if the tubular bag body 8 starts to be corroded, decomposed or dissolved in water by external force such as rain, wind, animals, etc. There is a possibility that the mixture other than 9A becomes lumpy and becomes an obstacle, and the seed 9A cannot be dropped onto the slope A, remains in the sheet-shaped support 2, and is dried. However, in this embodiment, the vegetation base material supplement pouches 10, 10, ... Are disposed between the vegetation base material bags 7, 7 ,. The vegetation base material supplement pouch 10 is supported by the sheet-shaped support 2 in a state of being separated from the slope A. However, since the vegetation base supplement pouch 10 is mainly filled with seeds 9A, the pouch body 11 is subjected to external forces such as rainfall, wind, and animals. When the seeds 7A are corroded, decomposed or dissolved in water in response to this, the seeds 7A are sequentially dropped without being left in the sheet-like support 2 and supplied to the slope A, so that the slope A is free from uneven planting. It is possible to prevent such a situation from occurring.

In this embodiment, the sheet-shaped support 2 is described as the upper net portion 3 and the lower net portion 4 formed as separate members, and these members are superposed on each other. The lower net portion 4 and the lower net portion 4 may be integrally knitted by using a knitting machine.

The interval between the vegetative base material bags 7, 7, ... To be inserted into the sheet-shaped support 2 may be determined according to the soil quality of the slope A, for example, in the case of bad soil or hard soil. It is good to narrow the interval.

In addition, in this embodiment, one vegetative base material bag 7 is attached to the sheet-like support 2 with a predetermined distance from each other, and one vegetation base material bag 7 is provided between the vegetative base material bags 7. The complementary pouch 10 is arranged. However, since it is necessary to change the interval of the vegetative matter depending on the construction site, for example, as shown in FIG. 3, a set of two vegetative base material bags 7, 7 is attached to the sheet-like support 2, You may make it the structure which arrange | positions two or more vegetation base material supplement sachets 10 and 10 between each group.

Further, in this embodiment, the sheet-like support 2 is covered with the wire net 12, but when the slope A of the slope A is a gentle slope of about 45 degrees or less, the wire net 12 is not used. May be.
