DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of planting flowers and trees on steep slopes of rocks and mortar, etc., using a retaining stopper for preventing the flowers and trees from flowing out and collapsing due to rainfall or the like. In particular, the present invention relates to a revegetation method such as a slope, in which a holding strap is used to prevent a vegetation bag accommodating a seedling that has not been rooted shortly after construction from falling off.

[0002]

Background of the Invention In recent years, in order to maintain the landscape by folding roads and riverbanks, instead of simply covering the side of the road or the steep slopes of the riverbanks caused by this construction with mortar or laying concrete blocks, Attempts have been made to plant plants, such as grasses, flowers, and trees, on the entire surface or in one section.

[0003] When planting plants on such steep slopes, in order to ensure the establishment of the plants, blow the soil as thick as possible on these steep slopes, dig holes and plant seedlings, or plant seedlings in pots. Although there is a method of planting, the seedlings do not fit the soil and cause poor growth, and even the rooted seedlings are washed away by heavy rain etc. both in the soil and the seedlings, making it difficult to establish the seedlings. Was.

[0004] From such a background, the present applicant has devised a new support member for plants (seedlings) and has already registered a utility model as a "stopper for earth retaining" (Registration No. 2541425).
The design registration (registration No. 938005) has been completed as a "earth retaining frame material". Furthermore, a patent for a "greening method such as a slope using a soil retaining stopper" that supports a vegetation bag containing soil and seedlings suitable for a seedling using the soil retaining stopper (Japanese Patent No. 266031)
No. 5), and the problem of the establishment of the seedlings on the slope has already been solved.

[0005] However, as shown in FIG. 8, when the slope 2 ', which is a construction site, is concrete or rock,
A hole for driving the pin 5a 'for fixing the vegetation bag 4'
After piercing the slope 2 'and placing the vegetation bag 4' on the retaining stopper 1 ', the vegetation bag anti-falling plate 5' is used, or the pin 5a 'is driven alone. However, there is room for improvement in the following points. That is, since the hole is hidden by the vegetation bag 4 ', the unstable working condition on the slope also makes it difficult to position the pin 5a', and the pin 5a 'may fall, resulting in the construction. This may lead to increased time and danger.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The "greening method for slopes and the like" of the present invention will be specifically described below with reference to the drawings. The reference numeral 1 in the drawing is a retaining stopper. This is an example of a construction surface.
When spraying the soil 3 for slope greening, it is used for the purpose of ensuring that the soil 3 is sprayed and preventing the soil 3 from flowing out and collapsing. Is supported in a state where it is accommodated in the vegetation bag 4.

The earth retaining stopper 1 used for such a purpose is constituted by a stopper plate 10 and a stopper pin 14, of which the stopper plate 10 has a
This reinforcing bar 1 is used as a frame member.
1, a net 12 is stretched, and two sleeves 13 are provided on one surface of the net 12. The size of the stopper plate 10 is, for example, 45 cm × 8 cm.
Although the size is used, the size can be variously changed according to the application.

In the embodiment shown in FIGS. 1 to 3, the net 12 constitutes a structure passing through the root 7 of the plant 6, but in addition to this, a number of holes are provided on a flat plate, One having a plurality of slits can be employed. Further, FIGS.
By using the reinforcing steel bar 11 in the embodiment shown in FIG. 1 and providing small round rods at a certain interval in a saw-tooth shape, it is also possible to form a structure through which the root 7 of the plant 6 passes. The shape of the stopper plate 10 is a flat plate as shown in FIG. 3 (a), which is the most versatile and easy to use. As shown in FIGS. 3 (b) and 3 (c), it is possible to adopt a basket-like configuration in which both ends stand vertically or diagonally.

Next, the holding strap 15 will be described. As shown in FIG. 4 (a), this is provided with hooks 15b at both ends of a rubber band 15a having a length of about 30 cm, which is an elastic body.
5b is formed by appropriately bending a metal plate to clamp the rubber band 15a, and bending its tip into a hook shape. The material of the rubber band 15a is preferably made of biodegradable synthetic rubber in consideration of the environment. By the way, when synthetic rubber is used as the rubber band 15a, the durability in a state where the rubber band 15a is left in the soil is maintained for about two years, during which time the plant 6 retains the soil 3, the stopper plate 10, the lath net 9 and Since it takes root in the slope 2, the strength at that time is not required.

As shown in FIG. 4 (b), the holding strap 15 may be configured such that both ends of a spring, which is an elastic body, are bent into a hook shape to form a hook 15b. Further, as the holding strap 15, a member other than an elastic body can be used.
(C) shows an embodiment using a synthetic resin fiber belt 15c as an example. This type of retaining strap 15
Connects two belts 15c each having a hook 15b at one end by a buckle 15d, and the buckle 15d may be of a suitable fastening mechanism such as a cam type or a ratchet type.

Next, the vegetation bag 4 will be described. As shown in FIG. 7, the vegetation bag 4 uses a fiber netting 4A made of resin fibers so as to allow ventilation, water passage, and passage of the roots 7 of the plant 6. The mixed soil 4B adapted to the seedlings of the plant 6 is housed inside. In the present embodiment, resin fibers are used as the material of the fiber netting 4A, but biodegradable resins or plant fibers such as hemp and cotton can also be used.

The various members used in the "greening method for slopes" of the present invention are formed as described above. Hereinafter, the "greening method for slopes" of the present invention will be described. First, FIG.
As shown in FIG. 2, a lath net 9 is provided on the slope 2 with a spacer 8 interposed therebetween. Next, the soil retaining stopper 1 is fixed to the slope 2 by adjusting the position of the stopper plate 10 to an appropriate position by inserting the stopper pin 14 into the sleeve 13 and driving the tip of the stopper 1 into the slope 2. . Incidentally, at this time, it is preferable to pre-perforate the slope 2 with a drill or the like.

Then, a plurality of earth retaining stoppers 1 are shown in FIG.
As shown in FIG. 3A, a fixed interval is provided in a staggered manner (in the present embodiment, a vertical interval is set to 50 cm and a horizontal interval is set to 60 cm). The reason why the earth retaining stoppers 1 are provided in a staggered manner is that, when the earth retaining stoppers 1 are arranged vertically and horizontally, the space between the adjacent earth retaining stoppers 1 and the water passageway. This is to prevent the customer's soil 3 from being easily collapsed. Further, in the present embodiment, as an example, the width is 45c.
A relatively small earth retaining stopper 1 having a depth of 8 cm and a depth of 8 cm is used in order to easily adjust the mounting position according to the unevenness of the surface of the slope 2.

At this time, the hook 15b provided at one end of the holding strap 15 is attached to the reinforcing steel bar 11 or the mesh body 12 in the stopper plate 10 of each earth retaining stopper 1.
Is engaged. This attachment may be performed after the soil retaining stopper 1 is installed on the slope 2, but the tip of the hook 15 b is bent in advance in a factory to be integrated with the stopper plate 10, and does not fall off from the reinforcing steel bar 11 or the net 12. It is preferable to do so.

Then, when all the retaining stoppers 1 are attached, as shown in FIG.
A mixed soil 4B suitable for plants 6, such as flowers and trees, and a vegetation bag 4 containing fertilizer are placed on the retaining stopper 1. At this time, the reinforcing reinforcing bar 11 in the stopper plate 10
Alternatively, the holding strap 15 is stretched between the net 12 and the lath net 9 or between two points of the reinforcing reinforcing bar 11 or the net 12 on the stopper plate 10. Figure 1,
2 and 5 show the reinforcing bar 1 in the stopper plate 10.
FIG. 6 shows a state in which the holding strap 15 is stretched between the mesh member 1 or the mesh body 12 and the lath net 9, and shown in FIG. Is stretched.

As described above, the vegetation bag 4 is held by the retaining strap 15 so as to be pressed against the earth retaining stopper 1 and the lath net 9, but when a part of the slope 2 is an extremely steep slope, this is not possible. Only on the part, the vegetation bag anti-falling plate 5 may be applied to the middle part of the vegetation bag 4 installed as shown in FIG. .

After the above construction method, plants 6 such as flowers and trees are cut open at the top of the vegetation bag 4 as long as the roots 7 of the plants 6 can enter. Also, for simplification of the construction method, the plant 6 such as a flower or a tree may be installed on the retaining stopper 1 in a state of being planted in the vegetation bag 4.

When all the plants 6 have been planted, the soil 3 is sprayed sequentially as shown in FIGS. 1 and 2 to complete a series of slope greening operations. Of course, the spraying of the soil 3 may be performed before or after the installation of the vegetation bag 4.

Since there is a suitable planting time for the seedlings, in the case of out of season, only the vegetation bag 4 containing the mixed soil 4B suitable for the plant 6 is installed and the soil 3 is sprayed. The plant 6 can be safely grown by implanting the.

[0024]

[Other Embodiments] In the above embodiment, two sleeves 13 are provided on one surface of a mesh body 12 as soil retaining stoppers 1, and stopper pins 14 are inserted through the sleeves 13. The type in which the tip is driven into the slope 2 is used, but the stopper pin 14 is previously driven into the slope 2 without providing the sleeve 13, and then the stopper plate 10 is fixed to the stopper pin 14. Can also be used.

In the above embodiment, the construction example of the present invention has been described assuming a steep slope of rock or mortar generated by road construction or river bank construction. It can also be applied to tree planting in the country.

[0026]

The "greening method for slopes and the like" of the present invention has the above-described structure, and thereby has the following effects. First, it is possible to prevent the vegetation bag 4 containing the seedlings that have not been rooted shortly after construction from falling off. The retaining strap 15 is stretched between the reinforcing reinforcing bar 11 or the mesh body 12 of the retaining stopper 1 and the lath net 9 or between two points of the reinforcing reinforcing bar 11 or the mesh body 12 of the retaining stopper 1. Therefore, construction can be performed reliably, quickly, and easily.

Further, between the reinforcing bar 11 or the net 12 in the retaining stopper 1 and the lath net 9, or the reinforcing bar 11 or the net 1 in the retaining stopper 1 is provided.
2 can be easily stretched between two points. In particular, when rubber is used as the elastic body, the holding strap 15 can be manufactured at low cost, and the danger when the holding strap 15 drops can be reduced.

Furthermore, since the holding strap 15 is integrated with the earth retaining stopper 1, it is possible to prevent the holding strap 15 from dropping, so that the construction time is not increased and danger can be eliminated.
