Description

[0001]
[Industrial application fields]
The present invention relates to a planting seedling planting method such as a cut slope, a hard rock slope, a mortar spray layer, a greening slope planting the planted seedling, and a soil bag for planting seedlings. In the construction of planting with bags, the roots of planted plants are steadily cultivated and grown by changing the structure or members and materials on the front side exposed to the atmosphere and the back side in contact with natural ground. The purpose is to promote.
[0002]
[Prior art]
In recent years, there has been an increase in the desire to use the slope as a place to restore the natural environment and the human environment, and the forestation of the slope is being promoted. In this case, the method of forestation by sowing has been adopted, but there are still many problems, and the current method is to rely on the method of planting shrubs.
[0003]
[Problems to be solved by the invention]
However, the existing existing methods include the so-called green pocket method (for example, Japanese Patent No. 222569, “Japanese Patent Publication No. 2-52050”, Utility Model Registration No. 1947806, “Japanese Utility Model No. 4-15797” provided by the applicant of the present invention). No.)), etc., and the results of greening have increased. Because of the hermetic construction in which the opening of the customer's bag by mortar spraying is drawn into a purse-like shape, it retains moisture well and is quite strong against drying. However, it will also require considerable labor and machinery costs, such as installation of a sandbag and spraying.
In addition, there are many methods of planting seedlings grown in pots by installing a clay soil bag such as a sandbag, but the reality is that they have not taken much measures against drying.

【Example】
Embodiments of the present invention will be described below with reference to the drawings. In the figure, 1 is a slope in which a vegetation base layer is formed on a natural ground, 2 is a bag for customer land for installation on slope 1, and has a purse-like opening 3 at the top, and the bag The surface 4 exposed to the atmosphere and sunlight of the body is a corrosion resistant sheet of the inner and outer double structures 41 and 42, and the heat insulating material 5 is stored between the sheets of the inner and outer double structures 41 and 42. .
The customer land bag 2 is formed by folding the surplus sheet 44 on the lower end side inward, or attaching the surplus sheet with another impermeable material and folding it.
Further, as the heat insulating material 5, granular lightweight aggregate (ALC), expanded polystyrene (EPS), expanded polystyrene volume reducing material, crushed stone, gravel, or the like is used. It is also possible to use recycled materials.
Further, there is a mixture obtained by adding a hardening material such as cement to the granular heat insulating material. The thickness t when the granular heat insulating member 5 is accommodated between the inner and outer double sheets is set to about 2 to 10 cm. Moreover, the back surface 43 which contacts the slope 1 is made of a material through which the roots of the grown plants can pass and can be replenished with water from natural ground. 6 is a water retaining hole opened in the horizontal direction of the slope surface from the part facing the bag 2 for customer land installed on the slope 1, and 7 is a water retaining member accommodated in the water retaining hole. It is possible to use a water-holding rope or string that has been crushed with a material such as cocoon or paper. 8 is the customer soil packed in the soil bag 2, 9 is a shrub planted from the opening 3, 10 is a sag prevention belt for preventing the customer soil bag 2 installed on the slope from hanging down, 11 Is an anchor pin for fixing the bag 1 for customer land.
[0012]
[Specific construction examples]
A specific construction example based on the above embodiment will be described. First, a single or a plurality of water retaining holes 6 are formed in the horizontal direction of the slope 1 where the customer land bag 2 is to be installed, and a rope-shaped or string-shaped water retaining member 7 is inserted into the water retaining hole. The tip portion 71 is exposed outside the slope 1. Next, the soil bag 2 filled with the soil 8 is placed with the anchor pin 11 with the front surface 4 containing the heat insulating material 5 facing the side exposed to the atmosphere and the back surface 43 on the slope 1. Fix it. Further, the sag-stopping belt 10 is held on the slope 1 by the anchor pin 11 while holding the bag 2 for customer land. And the shrub plant 9 is planted from the opening part 3 of a bag upper part, and the opening part 3 is obstruct | occluded by restrict | squeezing in the purse-like shape after the planting.
[0013]
In FIG.4 and FIG.5, while arrange | positioning the water absorption and water-permeable mat 61 between the slope 1 and the back surface 43 above the back surface 43 which contacts the slope 1 of the bag 2 for customer land. Fix with the anchor pin 11. The water-absorbing and water-permeable mat 61 is a dense net-like body such as a sponge mat set to a size of about 20 mm in thickness, 50 mm in length and 150 to 200 mm in width as shown in FIG. The water-absorbing and water-permeable mat 61 absorbs flowing water on the surface of the slope 1 during rain, and supplies rain water into the customer soil bag 2 for the land. The surplus water is drained downward from the drainage port portion 25.
In addition, if the heat insulating material 5 is a granular lightweight aggregate or foamed polystyrene or foamed polystyrene volume reducing material or crushed stone or gravel, and further mixed with a hardener such as cement to the heat insulating material 5, When rainwater or the like is exposed to the surface exposed to the atmosphere and moisture is absorbed, the hardener such as cement hardens and the portion of the heat insulating material 5 is retained.
[0014]
In FIG. 6, since the storage part 45 is formed in a state where the surplus sheet 44 on the lower end side of the pouch body 2 is folded inward, the rainwater that has permeated the inside of the plow is drained. When it is done, a part of the water is stored.
[0015]
【The invention's effect】
Since the present invention has the above-described structure, the surface of the bag for home soil is extremely dry because it is exposed to the atmosphere and sunlight, but it is easy to dry. Since the loss is prevented and condensation occurs, the function of the land is fully demonstrated.
In addition, on the back side to be installed on the slope of the bag body, the roots pass through the sheet on the back side by the growth of the planted plant and enter the slope side, so that the roots are more reliably established.
Next, the water content of the natural ground is stably replenished into the bag by the water retention member inserted in the water retention hole opened on the slope side, and the planted plant can be reliably grown.
In addition, since the opening part of the bag for customer land is squeezed into a purse-like shape and tied after planting, invasion of weed seeds can be prevented from the opening part.
Furthermore, the rainwater can be supplied into the bag for the home soil by flowing down the running water on the surface of the slope during the rain by the water-absorbing / permeable mat. And surplus water can flow down from a drain outlet, and can drain. At this time, a part of the water is accumulated in the lower storage portion in the bag for the home soil, and an appropriate amount of water necessary for water retention can be held in the bag.
And the mortar spraying work to protect the bag for customer land installed on the conventional slope by using granular lightweight aggregate or foam polystyrene or foam polystyrene volume reducing material or crushed stone or gravel etc. This is unnecessary, and the cost can be reduced.
Moreover, in the case of the above-mentioned granular lightweight aggregate, foamed polystyrene, foamed polystyrene reducing material, or a mixture of crushed stone or gravel added with a hardening material such as cement, the surface exposed to the atmosphere is wet with rainwater or the like. When the material is absorbed, the hardened material such as cement is cured and the heat insulating material portion is retained, so that the surface side of the installed soil bag can be protected by a mortar sprayer. it can.
