Abstract

PURPOSE:To facilitate collapse prevention and greening of slope by providing a tube-like root leading string to a semi-spherical pot having open holes deformed with the growth of a plant, storing a plant such as a sort of tree therein, and projecting the front end thereof to the surface of slope to bury. CONSTITUTION:A tube-like root leading string is mounted to a semi-spherical pot 1 of synthetic resin, etc., at the same time, a plurality of open holes 4 and surface V cut grooves are provided, and they are so constituted that they can be deformed with the growth of a plant, After that, a plant 3 such as a sort of tree is stored in the pot 1, and it is so buried that the front end thereof is projected to the surface of slope. A water retention member, soil funguses, fertilizer, etc., are kept in the pot 1. According to the constitution, the collapse of slope is prevented and, at the same time, greening by trees can be easily made.

Detailed Description of the Invention

[0001]

[Industrial application] Embankment reinforcement slopes and planting of general steep slopes.

2. Description of the Related Art Conventionally, the greening of the embankment reinforcement slope has been carried out by planting grass and shrubs by means of a netting method, a customer sprouting area, and a vegetation sandbag. Moreover, the vegetation method for tall trees has not been found at present.

[0003]

However, the conventional greening method for embankment reinforcement has surpassed the primary level and does not have a sufficient permanent effect in terms of landscape and environment.

According to the present invention, by planting tall trees on the embankment reinforcement slope, the natural landscape can be regained permanently.
Moreover, it aims at providing the effect of slope protection.

[0005]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the embankment reinforcement slope surface planting method of the present invention uses a rooting cord for storing seedlings in a pot and guiding root growth from inside the pot. Hand it over to the outside and entangle it with the grit material. Then, the tip of the trunk is projected and embedded in the slope surface part and subjected to slope pre-rolling pressure.

[0006] The shape of the pot is a half type in which the upper part is round and the lower part is flat, and a cylinder is attached. Furthermore, when the roots become thicker due to the growth of seedlings, the kerfs formed on the inner surface of the pot act to deform the pot depending on the soil quality.

The root string has a round bar shape in which polypropylene material fibers are heat-adhesive composite fibers and is deformed in response to earth pressure. Then, soil bacteria and nutrients are mixed and retained in the fiber. He promotes the rooting of tree roots and promotes the action of changing the buried soil into a growing soil in the process of elongation.

Around the pot, a short cut of the root cord is mixed with the buried soil. This disperses the roots extending from the inside of the pot along with the root string and promotes rooting. Furthermore, even if the grown trunk falls by the wind, the roots are surely intertwined with the grit material, so the entire tree does not slip off and breaks from the top of the trunk. In addition, roots remain in the ground and the trunk grows again and protects the slope from collapsing.

Since seedlings can be grown in pots, they will not die even if left for a long time at the site, and planting work can be carried out without the need to carry in according to the progress of construction.

By incorporating an air supply pipe into the pot, oxygen is supplied to the soil in the pot to guide rainwater and promote seedling growth.

Trees can be planted even when the slope tip of the embankment reinforcement slope is the vegetation soil pile construction method or the unrolling compaction construction method which is a normal civil engineering construction method.

[0012]

In the case of the present invention, by planting trees on the embankment reinforcement slope, the natural landscape is restored, and since the trees are entangled and rooted in the grit material, the slope slope is protected and permanent. Form a greenery.

EXAMPLES Examples of the present invention will be specified below.

The pot has a size of 30 cm × 30 c.
A V-cut groove with a depth of 1 mm is formed in a circular arc shape from the head center with a m × 20 cm plate thickness of 2 mm made of a synthetic resin material and a semi-circular upper part. Further, the lower part is made into a saucer type so that the upper part and the lower part are engaged with each other and sandwiched. The trunk-covering cylinder has a diameter of 10 cm × 50 cm and is provided with a spiral V-cut groove on its inner surface to be half-divided.

Embankment Reinforcement Method As shown in FIG. 2, the pot is set on the grit material with the tip of the trunk protruding by about 5 to 10 cm. Opening diameter of the introduction hole of the root string 13m
There are 9 m holes and 7 holes with a diameter of 19 mm. Push one end of the root string into these with a gold rod for about 3 to 5 cm, and grit material (trade name: Paragrit EXONCH
EMICAL manufacturing) and hand it over. The root cord is cut to an appropriate length depending on the part to be used.

For the soil around the pot, a root string was cut into a length of about 5 cm, and the soil was 5 m per 0.1 m ^{3 of} soil.
Mixing about 0 bottles, length 50 cm around the pot, height 30
Fill embankment to about cm, cover with other buried soil, and apply front roll pressure.

After 3 weeks, germination of new shoots was observed from the seedlings of the Knu tree planted in the pot.

[0018]

As described above in detail, the embankment reinforcement slope surface planting method of the present invention enables the natural landscape to be depicted by planting tall trees to realize permanent greening and to achieve slopes. Prevent the collapse of the, stable protection.
