BACKGROUND OF THE INVENTION
The present invention relates to a construction method using a retaining stopper for preventing the outflow and collapse of these flowers and trees due to rain and the like when planting and planting flowers and trees on steep slopes of bedrock and mortar. It is related to the revegetation method such as a slope, which prevents the vegetation bag containing seedlings that have not taken root soon after construction.
[0002]
BACKGROUND OF THE INVENTION
In recent years, in order to fold road construction and riverbank construction and maintain the landscape, instead of simply covering the steep slopes of the roadside and riverbank with this construction with mortar or laying concrete blocks, it is a whole surface or a section of it. Attempts have been made to plant plants such as grass, flowers and trees.
[0003]
When planting plants on such steep slopes, in order to ensure the establishment of the plant, blow the soil as thick as possible, dig holes and plant seedlings, or plant pot seedlings on this steep slope slope Although there is a construction method, seedlings do not match the soil, causing poor growth, and even the seedlings that have deeply rooted may be washed away due to heavy rain, etc., making it difficult to establish seedlings.
[0004]
From this background, the present applicant has devised a new support member for plants (seedlings), and has already been registered as a utility model (Registration No. 2541425) as a “stopper for soil retaining”. As a design registration (registration No. 933005). In addition, a patent (Patent No. 2660315) also uses this earth retaining stopper to support a vegetation bag containing soil suitable for seedlings and seedlings. The problem concerning the establishment of the seedling slope has already been solved.
[0005]
However, as shown in FIG. 8, when the slope 2 'as the construction site is concrete or rock, a hole for driving a pin 5a' for fixing the vegetation bag 4 'is drilled in the slope 2'. In addition, after placing the vegetation bag 4 'on the earth retaining stopper 1', the vegetation bag recoil prevention plate 5 'can be used, or the pin 5a' can be driven alone. There was room for. In other words, since the hole is hidden by the vegetation bag 4 ', it is difficult to position the pin 5a' due to unstable working conditions on the slope, and the pin 5a 'may fall, resulting in construction. It can lead to increased time and danger.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the “revegetation method for slopes” of the present invention will be specifically described based on the drawings. What is indicated by reference numeral 1 in the figure is a stopper for earth retaining. This is an example of the construction surface. When the soil 3 is sprayed on the slope 2 with steep slopes of bedrock and mortar, the soil 3 is sprayed for slope planting. It is used for the purpose, and finally supports a plant 6 for greening such as a flowering tree in a state where it is housed in a vegetation bag 4.
[0010]
And the stopper 1 for earth retaining used for such a purpose is composed of a stopper plate 10 and a stopper pin 14, and the stopper plate 10 includes a reinforcing member 11 having a U-shaped plane as a frame member. A mesh body 12 is stretched on the reinforcing reinforcing bar 11, and two sleeves 13 are provided on one surface of the mesh body 12. As the size of the stopper plate 10, a 45 cm × 8 cm size is used as an example, but the size can be variously changed according to the application.
[0011]
In the embodiment shown in FIGS. 1 to 3, the net body 12 forms a structure through which the root 7 of the plant 6 passes. In addition, a plurality of holes provided on a flat plate and a plurality of long hole-like slits are provided. The provided one can be used.
Further, by using the reinforcing reinforcing bars 11 in the embodiment shown in FIGS. 1 to 3, a through-hole structure of the root 7 of the plant 6 is formed by providing small round bars in a saw-like shape with a certain interval. You can also
In addition, the flat plate shown in FIG. 3 (a) is the most versatile and easy to use as the shape of the stopper plate 10. However, in the case where the use of a plant having a special shape is limited, As shown in 3 (b) and 3 (c), it is possible to employ a configuration in which both ends are vertically or obliquely raised.

Next, the holding strap 15 will be described. As shown in FIG. 4 (a), for example, the rubber band 15a having a length of about 30 cm, which is an elastic body, is provided with hooks 15b at both ends. The hook 15b is formed by appropriately bending a metal plate. The rubber band 15a is sandwiched and its tip is bent into a bowl shape. The rubber band 15a is preferably made of biodegradable synthetic rubber in consideration of the environment.
Incidentally, when synthetic rubber is used as the rubber band 15a, the durability in a state where it is left in the soil is maintained for about two years. During this period, the plant 6 is in the soil 3, the stopper plate 10, the lath net 9 and Since it takes root in the slope 2, strength at that time is not required.
[0013]
Further, as shown in FIG. 4 (b), the holding strap 15 can be configured to be hooked by bending both ends of a spring, which is an elastic body, into a hook shape. Furthermore, as the holding strap 15, a member other than an elastic body can be used, and FIG. 4C shows an embodiment using a synthetic resin fiber belt 15 c as an example. This type of holding strap 15 connects two belts 15c each having a hook 15b at one end by a buckle 15d, and this buckle 15d can be of a proper fastening mechanism such as a cam type or a ratchet type. .
[0014]
Next, the vegetation bag 4 will be described. As shown in FIG. 7, the vegetation bag 4 uses a resin fiber fine mesh body 4A so that ventilation, water flow and passage of the roots 7 of the plant 6 can be performed, and a plant is contained therein. 6 contains mixed soil 4B suitable for 6 seedlings. In the present embodiment, resin fibers are used as the material of the fiber net 4A, but it is also possible to use biodegradable resins or plant fibers such as hemp and cotton.
[0015]
The members used in the “greening method for slopes” of the present invention are configured as described above, and the “greening method for slopes” of the present invention will be described below.
First, as shown in FIGS. 1 and 2, a lath net 9 is stretched over the slope 2 via a spacer 8. Next, the stopper 1 for earth retaining is fixed to the slope 2 after the stopper pin 14 is inserted into the sleeve 13 and the tip of the stopper pin 10 is driven into the slope 2 to adjust the position of the stopper plate 10 to an appropriate position. . At this time, it is preferable to drill the slope 2 in advance with a drill or the like.
[0016]
As shown in FIG. 5 (a), the plurality of earth retaining stoppers 1 are staggered at regular intervals (in this embodiment, the vertical interval is 50 cm and the horizontal interval is 60 cm) with respect to the slope 2. To provide shelves. The earth retaining stopper 1 is provided in a staggered manner as described above. When the earth retaining stoppers 1 are arranged vertically and horizontally, a water passage is formed between adjacent earth retaining stoppers 1. This is to prevent the collapse of the customer land 3 and prevent this. In this embodiment, a relatively small earth retaining stopper 1 having a width of 45 cm and a depth of 8 cm is used as an example, but this can be easily adjusted according to the unevenness of the surface of the slope 2. It is to do.
