Description

  The present invention relates to a vegetation tool and a mortar slope greening method using the vegetation tool, and more particularly, to a technique for permanently reinforcing and greening a mortar slope that has deteriorated over time with a vine such as a lath net and ivy.

  Conventionally, on the side of a road or a private house, a mountain is opened and the slope is blown with mortar to strengthen the slope. On the other hand, in recent years, environmental awareness has advanced, and mortar exposure is not preferred, and harmony with nature is preferred. Therefore, greening has been attempted, such as putting plants on existing mortar slopes.

However, the conventional technique has the following problems.
First, because the surface was covered with mortar, there was a problem that plants were difficult to grow.
In addition, when the slope is about 60 ° or more, there is a problem that even if it is a ivy or the like, the stand alone does not fully grow and the plant is difficult to settle.

  The existing mortar surface is prone to cracking and peeling of the mortar due to changes over time, and the plant may be peeled off together with the soil mass before it roots, so that the vegetation as designed cannot be realized. was there.

Japanese Patent No. 3935191 JP 2009-228211 A JP 2009-24440 A JP 2005-611144 A Patent No. 3935191

  ADVANTAGE OF THE INVENTION According to this invention, the vegetation tool and construction method which reinforce or maintain the existing mortar slope and green well can be provided.

It is explanatory drawing which showed the structural example of the vegetation tool of this invention. Among these, FIG. 1A is a partial cross-sectional view, and FIG. 1B is an explanatory view showing a state in which the core material enveloping body is wound around the core material. It is an enforcement conceptual diagram of the mortar slope greening method of this invention. Among these, Fig.2 (a) shows the existing mortar slope cross section, FIG.2 (b) has shown the same front view.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a conceptual diagram of a vegetation tool according to the present invention. FIG. 2 is a diagram showing a construction example of greening of an existing mortar slope using a vegetation tool. In the drawing, the scale and the like are omitted as appropriate for convenience of explanation. As shown in the figure, the vegetation tool 1 includes a core material 11, a core material encapsulating body 12, a water retention material layer 13, a nonwoven fabric layer 14, an outermost layer 15, and a pot 16 as main components, and soil. It is a vegetation tool that is inserted into a cylindrical hole drilled to grow a vine. The core material encapsulation body 12 to the outermost layer 15 are wound around the core material 11 with the same width.

  The core material 11 has a shape in which a stainless steel wire 1.2 m having a diameter of 2 mm is folded in two and a tip 4 cm is folded back to form a hook.

  The core enveloping body 12 is made of soft polyethylene having a thickness of about 1 mm and a width of 5 mm, and is a spiral tube that naturally winds with an inner diameter of about 5 mm, and is wound around the outside of the core material 11. The core material envelope 12 can secure an air layer that communicates with the hook side. Although some water may enter, since the material itself has a predetermined water repellency and a gap is secured even between the core materials 11, the inside of the core material encapsulation body 12 is generally good. Breathability is ensured.

  The water retaining material layer 13 is filled with a water absorbing polymer, and absorbs and retains water. During water absorption, the water retaining material layer 13 expands to tightly fill the cylindrical hole, and increases the strength of the vegetation tool 1 together with the outermost layer 15 so as not to be crushed by the soil. The water-absorbing polymer may be filled alone, but may be supported on cloth or paper. Further, the water retention material layer 13 contains a nutrient (fertilizer) in advance.

  The nonwoven fabric layer 14 is a layer formed by wrapping a nonwoven fabric around the outside of the water retention material layer 13, and appropriately retains the moisture content of the water retention material and soil and retains fine air bubbles. In addition, dissolved oxygen propagating from the central air layer is also supplied. The nonwoven fabric can promote root stretching from its shape or properties, and can stretch the root to the deep part along the nonwoven fabric. The nonwoven fabric layer 14 contains nutrients (fertilizer) in advance.

  The outermost layer 15 is a layer that wraps the nonwoven fabric layer 14, and ensures a predetermined strength by the mesh base material and assists the extension of the root to the soil. The material is not particularly limited as long as it does not hinder plant growth, and examples thereof include polyethylene, polypropylene, and polyvinyl chloride. An example in which the size of the eyes is 3 mm × 3 mm and the thickness between the eyes is 1 mm can be given.

  The pot 16 is inserted into the middle of the soil so as to surround the upper surface of the cylindrical hole, and a seedling of a vine plant is placed therein. The pot 16 has no bottom, and the roots extend along the nonwoven fabric or mesh. The material is a weather resistant resin. The shape is a tapered cone.

  The vegetation tool 1 is configured as described above, and is inserted into a cylindrical hole opened in the soil, leaving the hook portion, and the lower edge of the pot 16 is inserted into the soil. The pot 16 is fixed and used by being locked to a later described. Put the seedlings of soil and vines in the pot 16 to make sure that the rooting is thorough, vines and leaves are attached to the lath net, and the mortar slope described below is greened and reinforced.

Next, the mortar slope greening method using the vegetation tool 1 will be described.
Here, the slope to be greened is an existing slope covered with 5 cm thick mortar, and the slope angle is 65 °. Moreover, the example which grows the ivy which is an evergreen vine as a vine plant is given.

  First, a 50 cm deep hole is dug on the mortar slope using a bit having an outer diameter of 5 cm (vegetation hole drilling step). Actually, the diameter of the hole expands when drilling, and becomes a hole having a diameter of about 7 cm. Holes are drilled at intervals of 1 m in the climb direction (vertical direction) of the slope and at intervals of 2 m in the lateral direction.

  For drilling, an anchor method (Japanese Patent No. 3935191) by the present inventor can be used. In the actual site, various factors such as the size of the slope area, inclination, curvature, etc. overlap, and it may be difficult to assemble the scaffold, but using the anchor method, it is possible to drill holes easily and inexpensively with no scaffold, Suitable for slope planting.

  Next, as shown in FIG. 2, a water guide made of cement having a thickness of 1 cm and a length of 20 cm is provided so that rainwater flows into the hole (installation step).

  After cement curing, cover the slope with a lath net (coating process). Use fixtures, etc. as appropriate so that they do not slip. Note that a lath net having a rust-proofing treatment is used. Here, a diamond-shaped eye having a diagonal line of 8 cm × 6 cm is used. By covering with a lath net, peeling of the existing mortar due to aging or the like is prevented.

  Next, the vegetation tool 1 is inserted into the hole (insertion step). Regarding the pot 16, the bottom edge is inserted into the hole so as to be oriented vertically upward, and the hook is hung on a lath net and fixed. At this time, the hook 16 and the upper part of the core material 11 are appropriately bent to fully fix the pot 16 (fixing step).

  Finally, soil and ivy cuttings are placed in the pot 16 to complete the process (greening process). The upper part of the core encapsulant 12, the upper part of the water retaining material layer 13, the upper part of the nonwoven fabric layer 14, and the uppermost part of the outermost layer 15 are exposed from the soil put in the pot 16 so that the air layer communicating to the lower part of the core material 11 is exposed to the outside air. To.

  After installation, it rains, water enters the hole through the water guide, and the water retaining material of the water retaining material layer 13 absorbs water and expands. The pot 16 becomes a moist environment, the roots extend from the ivy, and the nutrients are supplied from the water replenishing material layer 13 and the nonwoven fabric layer 14 as appropriate to grow.

  As the plants grow, the roots further extend through the nonwoven fabric layer 14 and the outermost layer 15. At this time, since oxygen is supplied by the air layer of the core material 11, the roots expand wider and deeper than usual. In addition, the ivy leaves and vines spread along the lath net, and suitable greening is achieved. Moreover, since the mesh of the lath net is effectively blocked by leaves and vines, mortar peeling and soil runoff are further suppressed.

  As described above, according to the present invention, it is possible to provide a vegetation tool and a construction method that can reinforce or maintain an existing mortar slope and can be well greened.

  The present invention is not limited to the above embodiment. Examples of vines include fern plants such as urajiro, cynomolgus, and japonica, gymnosperm, scorpion, akane, akebi, calla, canamgra, staghorn, hydrangea, pebbles, quince, vine Tsurugikyo, Teikakazura, Ginseng, Boran Kuzuru, Hansou Kuzuru, Kazaguruma, Snail, Bear Willow, Pepper Kuzura, Tsurugakudami, Aotsuki Rafuji, Passiflora, Tsurumukidoki, Tsurumasaki, Kuzura, Yasura Dicotyledonous species such as kusa-fuji, yellow-bellied bean, arabidobikazura, matatabi, kiwifruit, fusenka-zura, tsururin-do, etc. Kazura, Smilax china L., Tsuruadan, Toutsurumodoki, etc. may be mentioned. Monocots such as tow, when used in reinforcing and afforestation of mortar slope may be selected as preferred from a suitable them.

  Further, the target slope is not limited to the mortar spray surface, and may be a concrete surface. If the angle of the slope is large, the pot shape may be L-shaped so that it can be inserted into a drilled hole (mortar hole).

  According to the present invention, it is possible to provide a method for efficiently greening an existing mortar slope. In addition, by using a scaffolding hole, a vegetation hole can be easily drilled, and inexpensive repairs can be made.
