Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for supporting and constructing trees, more specifically, a park,
The present invention relates to a tree supporting construction method for constructing a tree while artificially planting it on a pavement or other outdoor venue.

(Prior Art) Conventionally, as a prior art related to the present invention, Japanese Patent Laid-Open No. 62-
There is a method described in Japanese Patent No. 195225.

As shown in FIG. 8, the cord material 13 is provided between the support 8 externally fitted to the root portion 4 of the tree 1 and the fixing member 12 that is previously driven into the hole 2. This is a method in which the root portion 4 of the artificially planted tree 1 is supported in the ground by stretching the material 13 along the root pot 3.

(Problems to be Solved by the Invention) However, the above method has the following problems.

That is, in the above method, the string material 13 often bites into the root pot 3, the root pot 3 is collapsed, the string material 13 is loosened, and as a result, the tree supporting operation itself becomes unstable.

Further, when the root pot 3 is collapsed, not only the root system that bears its growth on the soil constituting the root pot 3 but also the growth of the whole tree is inhibited.

In addition, in the above-mentioned conventional method, as shown in FIG. 8, a member 14 for preventing the cord material 13 from biting into the root pot 3.
Is attached to the shoulder of the root pot 3 to prevent the cord 13 from biting into the shoulder of the root pot 3 to some extent, but the cord 13 also bites into the part of the root pot 3 other than the shoulder, and as a result, The whole root bowl 3 will be collapsed. Therefore, although the member 14 has some effect, it is very unsatisfactory to prevent the cord 13 from biting into the root pot 3 as a whole.

The present invention has been made in order to solve all of the above problems, and artificially planting without causing instability of support construction due to the collapse of the root pot 3 and inhibition of the root system and thus the growth of trees. The purpose is to support the construction of the trees.

(Means for Solving the Problem) The present invention has been made to solve the above problems in order to achieve such an object, and the means for solving the problems are formed in advance on the ground. For supporting and constructing the tree 1 to be planted by accommodating the root portion 4 of the tree 1 in the planting hole 2, closing the planting hole 2 with soil or the like, and burying the root portion 4 in the ground. In support construction method of tree,
At least the upper surface and the shoulder of the root pot 3 of the tree 1, a net-like shape made of a flexible material in which a hole 9 is formed substantially in the center and an opening crevice 10 communicating with the hole 9 is formed in at least one place. Of the cover body 5, and then the peripheral edge 6 of the hole 9 of the cover body is fastened to the peripheral edge of the root portion 4, and then the lower end portions 7, 7 ... The purpose is to support and construct the tree 1 to be planted by being stretched on the inner wall surface via the fixing members 12, 12 ...

(Operation) That is, since the present invention has the above-described configuration, first, the opposite edges of the opening crevice 10 of the cover body 5 are separated, and the hole portion 9 communicating with the opening crevice 10 is further expanded. Next, by fitting the expanded hole 9 into the root 4 of the tree 1 and closing the opening crevice 10, the peripheral edge of the hole 9 of the cover body 5 is fastened to the peripheral edge of the root 4. The Rukoto. Next, the lower end portions 7, 7, ... Of the cover body 5 are stretched on the inner wall surface of the planting hole 2 via the fixing members 12, 12 ,. As a result,
The whole root pot 3 is planarly covered with the net-shaped cover body 5. Also, several points of the lower end of the net-shaped cover body 5 are pulled downward and stretched on the inner wall surface of the planting hole 2, and linear tension is applied to the cover body 5, so that the root bowl 3 is also linearly maintained. Of course, in this case, since the cover body is a net made of a flexible material, the cover body does not cut into the root bowl 3. Therefore, the root bowl 3 will not be collapsed due to the biting of the cord material as in the conventional case.

As a result, the root pot 3 and the soil constituting the root pot 3 are covered with the cover body 5 and are always stably fixed to the inner wall surface of the planting hole 2.

(Example) Hereinafter, one example of the present invention will be described with reference to the drawings.

The cover body 5 used in the present embodiment is made of synthetic resin, and as shown in FIGS. 1 (a) and 1 (b), the whole is net-like and has a substantially circular hole at its substantially central portion. 9, over the entire circumference 6 of the neck portion 9 and at both ends 17a, 1 thereof
A bag-shaped portion 17 having an opening 7b, a string 18 inserted into the bag-shaped portion 17 and having both ends 18a and 18b protruding from both ends 17a and 17b of the bag-shaped portion 17, respectively, and the peripheral edge 6 It consists of a tear 10 extending from one point to one side of the cover body 5.

In this embodiment, first, as shown in FIG. 2, the opposite edges 10a and 10b of the crevice 10 of the cover body 5 are separated and the neck portion 9 is further expanded.

Subsequently, as shown in FIG. 3 (a), the neck portion 9 that is expanded is fitted into the root portion 4 of the tree 1, and the crevice 10 is closed.

After that, as shown in FIG. 3 (b), the peripheral edge 6 of the neck portion 9 is set to the root portion 4, and both ends 18a and 18b of the string 18 inserted in the bag-shaped portion 17 of the peripheral edge 6 are set to the winch 15. Tighten by adjusting and tightening.

As a result, as shown in FIG. 4, the root pot 3 of the tree 1 is covered with the root portion 4 protruding from the neck portion 9 at the substantially center of the cover body 5, and the peripheral edge 6 of the cover body 5 is the root portion. It will be in a state of being fastened to 4.

This state, that is, the peripheral edge 6 of the neck portion 9 of the cover body 5
The cover body 5, the root pot 3, and the root portion 4 and thus the tree 1 which are originally separate when the root portion 4 is fastened to the root portion 4.
Are integrated. Therefore, if a downward tension is applied to the cover body 5, the tension acts so as to integrally pull the root pot 3, the root portion 4 and the tree 1 downward.

Next, as described above, the peripheral edge 6 of the neck portion 9 of the cover body 5 is
Is fastened to the root portion 4 and substantially the entire cover body 5 is in close contact with the root pot 3, the root portion 4 and the root pot 3 of the tree 1.
Are housed in the planting hole 2 as shown in FIG.

Next, the lower end portion 7 of the cover body 5 in which the root pot 3 housed in the planting hole 2 as described above is tightly wrapped and the peripheral edge 6 of the neck portion 9 thereof is fastened to the root portion 4 , 7, ...
As shown in FIGS. 6 (a) and 6 (b), the wires 13, 13, ...
, 13 are stretched over anchors 12, 12, ..., which have been previously driven into the bottom wall surface of the planting hole 2, via winches 15, 15 ,.

Here, the root pot 3, the root portion 4 and thus the tree 1 and the cover body 5, which are integral as described above, are integrated with respect to the downward external force hanging on them, that is, the tension between them and the anchor. It is possible to disperse stress in a plane and respond. Therefore, unlike the conventional case, the root bowl 3 is never collapsed by the cord material.

Finally, the planting hole 2 is filled with soil as shown in FIG. 7, and the supporting construction of the tree 1 artificially planted is completed.

As described above, in this embodiment, the root pot 3 is wrapped with the net-shaped cover body 5, and the net-shaped cover body 5 is provided.
The neck portion 9 is fastened to the root portion 4, and the net-like cover body 5 that is further stiffened is stretched around the anchor in the implantation hole 2. Therefore, the tension between the anchor and the net-shaped cover body 5 acts on the whole root pot 3, and the root pot 4, the root pot 3, the root portion 4 and the tree 1 are entirely supported and constructed.
Supporting construction of Tree 1 will be much more stable than before.

Further, in this embodiment, the root pot 3 is wrapped in a net-like cover body 5 on the upper surface and the side face thereof in a state of being in close contact with each other, so that the root pot 3 of the cord material, which has been a serious problem in the conventional technique. There is nothing to bite into. Therefore, there is no inhibition of growth of the root system due to the collapse of the root pot 3, and further the collapse of the soil mass that constitutes the root pot 3, and rather, the soil that constitutes the root pot 3 is surely retained by being covered with the cover body 5. Therefore, the growth of the root system and thus of trees is promoted.

In the above embodiment, the root pot 3 is covered with the cover body 5 before being housed in the hole 2, and the peripheral edge 6 of the cover body 5 is fastened to the root portion 4. The procedure is not limited to the procedure of the above-described embodiment as long as the covering and fastening can be performed, and the procedure of performing the covering and fastening after housing the root pot 3 in the planting hole 2 may be used.

Further, in the above-mentioned embodiment, the cover body is stretched on the anchors that have been driven into the inner wall surface of the implant hole 2 in advance. However, this procedure is not limited to the above-described embodiment, and the size of the implant hole and the anchor implants can be set. It can be designed according to the workability, etc.

In addition, in the above-mentioned embodiment, the root pot 3 is planarly covered with the net-shaped cover body on the upper surface and the side surface.
The coating of is not limited to this. The point is that the cover body covering the root pot 3 covers at least the upper surface and shoulders of the root pot 3 and is stretched on the lower anchor without collapsing the root pot 3.

Further, in the above-mentioned embodiment, since the net-shaped cover body 5 covers the root pot 3 in a plane, stress is not concentrated on the neck portion 9 of the net body, and the root portion 4 has the peripheral edge 6 of the neck portion 9.
Since it is not damaged by the above, the peripheral edge 6 is intentionally fastened directly to the root portion 4, but it is of course possible to interpose a protective member on the root portion 4.

Further, in the above embodiment, the synthetic resin cover body 5 is used.
However, it is not limited to synthetic wood as long as it has strength and workability that can withstand coating of root pot 3, tensioning to anchors, attachment of wires, and the like. In short, the cover body 5 is arranged along the root portion 4 of the tree 1 and the shoulder of the root pot 3,
It just needs to be made of a flexible material.

Further, in the above-mentioned embodiment, the root pot 3 does not collapse and there is no hindrance to the growth of the root system and thus the tree. However, when the growth is particularly required to be promoted, the cover body 5 has a net shape. In the mesh of the cover body 5, for example, a fertilizer bag is stored inside and a fertilizer bag for hanging the fertilizer out into the soil forming the root pot 3 with the passage of time and permeation of rainwater etc. Needless to say, it is easily possible to promote the growth of one layer of the tree.

(Effects of the Invention) As described above, in the present invention, the root pot is planarly covered with the net-shaped cover body, and the periphery of the hole of the cover body is fastened to the root portion of the tree to further increase the hardness. Several places at the lower end of the cover body are stretched on the inner wall surface of the planting hole.

Therefore, the present invention provides (1) a root pot and a root portion, and thus a tree, which is a net-shaped cover body made of a flexible material, is face-covered without causing collapse of the root pot, and is integrally planted. It is fixed to the cover body, and it is stretched downward so that several points of the lower end portion of the cover body are narrowed down, and the stress related to the tension acts linearly as well as linearly, so it is planted. The stability of supporting construction of trees becomes extremely high.

(2) Not only does the root system, and thus the growth of trees, be completely uninhibited due to the collapse of the root pot, but the net-like cover body keeps the root pot, in other words, the soil surrounding the root system, extremely stable. The root system and thus the growth of the tree are promoted. (3) Moreover, since a hole is formed at approximately the center of the cover body and an opening crevice is formed at least at one place in communication with the hole, a tree is formed. To attach to the root part of the cover, open the opposing edges of the opening crevice of the cover body, expand the hole, and fit the expanded hole into the root of the tree and open the crevice for opening. It can be easily done by closing.

Further, since the cover body is made of a flexible material and has a net shape, the peripheral edge of the hole can be easily aligned with the root portion and the cover body can be easily aligned with the shoulder of the root bowl. be able to.

Therefore, even when carrying out support construction of large plants such as trees, it is possible to easily attach it to the root and shoulder of the root pot,
The construction can be done easily, and the construction work is not hindered.

(4) Further, unlike the prior art, a large number of parts such as a ring body attached to a root portion, a block attached to a shoulder, a wire wound around a root pot, a fixing member such as an anchor are not required, and In addition to the fixing member, the net-shaped cover body as described above can be mainly used for construction, so that the number of parts required for construction can be significantly reduced compared to the conventional case.

This has led to an epoch-making effect not seen in the past.
