DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planting method for planting trees on slopes of cut and embankment.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 6, when a tree 70 is planted on a slope of a cut, a planting hole 72 large enough to receive a root pot 74 of the tree 70 is formed on the slope. Trees 70 were planted in the planting holes 72.

[0003] However, if the slope of the cut slope is steep, it is not easy to dig the planting hole 72 and it is difficult to install a column supporting the tree 70, so that the tree 70 may fall down due to wind and rain.

On the other hand, when the trees 70 are planted on the slope of the embankment, the planting holes 72 can be easily dug, but the embankment collapses due to the weather and the surface layer slides along with the trees 70, and the trees 70.
May not survive.

[0005]

SUMMARY OF THE INVENTION In view of the above facts, the present invention facilitates creation of an optimum planting base for planting trees, prevents erosion of slopes due to wind and rain, and improves tree planting. The task is to promote survival.

[0006]

According to the first aspect of the present invention, a box for forming a planting hole for planting is installed on a slope, and a continuous void hardened body is cast on the slope. Install the formwork. Next, a continuous void-cured body is poured into the mold, and after the continuous void-cured body is cured, the box is removed from the mold and the planting base is integrally formed with a porous planting hole. To build.

As described above, by constructing the planting base having the planting holes in-situ, it is not necessary to excavate the slope to form the planting holes. Moreover, even if the slope of the slope is steep, a planting hole can be easily constructed, and erosion of the slope is prevented by the planting base composed of the continuous void hardened body.

[0008] This planting hole is filled with good quality soil, and root pots of trees are planted. Also, by planting a herbaceous plant on the surface of the planting base with a thin layer of soil, the entire slope can be greened immediately after construction.

[0009] Furthermore, the roots of the trees can extend from the planting holes to the spaces of the planting base composed of the continuous space hardened material, so that the trees grow greatly. Moreover, by planting in the planting hole integrated with the planting base in this way, it is possible to prevent the tree from falling due to the wind and rain.

According to the second aspect of the present invention, the hook is embedded in the continuous gap cured body before the continuous gap cured body is cured. A rope or a support is fixed to the hook to support the planted tree.

1 to 4 show a planting base forming method according to a first embodiment.

In this embodiment, the present invention is applied to a concrete slope 12 for preventing collapse of a slope by spraying concrete on a ground 10 on the slope.

First, the bottom surface 12A of the concrete method frame 12
Then, the cylindrical void 14 is fixed with a not-shown streak. At this time, the mouth of the void 14 is cut obliquely in accordance with the slope of the slope, so that the root pot 18 of the tree 16 can be planted vertically as shown in FIG.

As shown in FIG. 1, the void 14
The weir plate 2 is arranged in a zigzag pattern at an interval where one planting hole 20 can be formed per 1 m ^{2 of the} slope,
2 is framed and fixed.

Next, as shown in FIG. 2, the continuous void hardened body manufactured in the plant is transported to a construction site by a dump truck, and is placed between the weir plates 22 by a backhoe or a hopper. Then, before the continuous void cured body is cured, the ring 2
Four hooks 26 with 4 are embedded around the void 14 and cured for about one week until a predetermined strength is developed.

In this embodiment, the hardened continuous void body is made of porous concrete having continuous voids, but may be one in which aggregates such as glasslets and slag are kneaded into concrete.

Next, the continuous void hardened material is hardened and the planting substrate 2
After the construction of 8, the void 14 is removed from the mold to obtain a hole 20 having a porous inner peripheral wall.

Here, as shown in FIGS. 3 and 4, soil, fertilizer, and a water retention material which has been made into a slurry by adding water to a neutralizing material are injected into the voids of the planting base 28, and thereafter, The soil 30 mixed with the native seeds and the grass seeds is sprayed thinly (about 50 mm) on the surface of the planting base 28. As a result, the roots of the germinated turf and the like extend into the voids of the planting base 28 to make the roots.

Also, high quality soil 32 is put in the planting hole 20 and the root pot 18 of the tree 16 is planted. After planting, the rope 34 is hung on the circular ring 24 of the hook 26, and this rope 3
At step 4, the tree 16 is fixed. In addition, when environmental conditions are severe, the irrigation hose 36 is arrange | positioned at the side of the planting hole 20, and the tree 1
6 may be replenished with water. Moreover, you may arrange | position so that the opening part of the irrigation hose 36 may be located directly in the hole bottom of the planting hole 20.

As described above, in the present embodiment, by constructing the planting base 28 having the planting holes 20 on the slope with the continuous void hardened body, the planting holes can be easily formed even if the slope of the slope is steep. 20 can be constructed and the planting base 28 prevents erosion of the slope.

Further, by planting a herbaceous material on the surface of the planting base 28 with a thin layer of soil, the entire slope can be greened immediately after construction. In addition, the root of the tree 16 is
From above to the planting base 28, so that the tree grows significantly. In addition, by hanging the rope 34 on the ring 24 of the hook 26 and fixing the tree 16 with the rope 34, it is possible to prevent the tree 16 from falling down due to wind and rain.

In this embodiment, the weir plates 22 are arranged in a lattice to form the planting base 28, but only the voids 14 are fixed to the bottom surface 12A of the concrete frame 12, and A planting base using 12B as a mold may be formed.

Naturally, the planting base can be formed not only on the concrete frame 12 but also on the slope to which the concrete is simply sprayed by the planting base forming method of the present embodiment.

Next, a method for creating a planting base according to the second embodiment will be described. As shown in FIG. 5, in the second embodiment, a planting base 40 is directly constructed on the slope 38 of the ground. For this reason, a mat 42 for correcting unevenness of the slope 38 is stuck to the slope 38 with pins 44. The mat 42 also functions as a buffer material for retaining water. In addition, the construction procedure of the planting base 40 and the tree planting method are the same as those in the first embodiment, and will not be described.

[0036]

According to the present invention having the above-described structure, an optimum planting base for planting trees can be easily formed, and erosion of a slope by wind and rain can be prevented. In addition, the entire slope can be greened immediately after the construction is completed.
