Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a tree support construction method, more specifically, to a park,
This invention relates to a tree support construction method for constructing while supporting trees artificially planted on pavements and other exposition sites.

(Prior Art) Conventionally, as shown in FIG. 7, a conventional method for supporting this type of tree is to attach a support 18 to the trunk 17 of a tree l, and to drive the support 18 into the ground to support the tree. As shown in Fig. 8, the wire 19
A method of supporting the tree 1 with the tension of the wire 19 by wrapping one end 19a side around the trunk 17 of the tree 1, attaching an anchor 20 to the other end 19b side, and driving the anchor 20 into the ground. There is.

(Problems to be Solved by the Invention) However, the above-mentioned support construction methods are all methods of supporting the trunk 17 of the tree l using the pillars 18 and wires 19, so the pillars 18, which are supporting members,
There was a problem in that the wires 19 were inevitably exposed underground and exposed to the outside, resulting in a significant deterioration of the appearance.

The present invention was made to solve these problems, and it eliminates the need for any members to support trees on the ground, such as the above-mentioned pillars, and allows trees to be planted without exposing the support structure to the outside. The purpose is to maintain the appearance of trees.

(Means for Solving the Problems) In order to achieve the above-mentioned purpose, the present invention solves the following problems: In view of the above-mentioned problems, this project aims to solve the above-mentioned problems by supporting the roots of trees buried underground. , a support is fitted around the base of the tree, and then the support is connected to a fixing member previously driven into the inner wall of the planting hole while pulling a string material, or the support and the fixing member are connected together. At the same time, the fixing member is driven into the inner wall surface of the planting hole while pulling the string material, and the root part of the tree is supported underground by the tension of the string material between the support body and the fixing member. The point is to do this.

(Function) In other words, in order to use this support construction method, tension is applied to the string material connected to the support body fitted around the root of the tree and the fixing member driven into the inner wall surface of the planting hole. As a result, the root part of the tree is supported by the tension of the string material, and the support body tightens the root part of the tree by the tension, so that the support body is securely attached to the root part.

After the root part is supported by these supports, strings, and anchors, the planting hole is filled with soil, etc., and the supports, strings, and anchors are all buried underground. The construction status is not exposed above ground.

(Example) Hereinafter, embodiments of the present invention will be described according to an example shown in the drawings.

First, as shown in Figure 1, the root part 3 and root ball 4 of the tree 1 are stored in the planting hole 2 previously formed in the ground, and then, as shown in Figure 2, the root part 3 of the tree 1 is filled with hemp. A net-like band 5 made of 100% is wrapped, and a support 8 in which a rubber hose 7 is fitted around a ring-shaped wire 6 is fitted on the outside of the band 5. still,
One end 6a of the wire 6 of this support 8 forming a ring is clipped to a predetermined position of the wire 6, and the other end 6b extending from the ring is bent and clipped. A pulley 10 is rotatably attached to the 6b side via a connector 9.

The support body 8 is attached to the root portion 3 of the tree 1 so that the pulleys 10 are positioned at four equal intervals as shown in FIG.
A total of four pieces are sequentially fitted on the top and bottom.

Next, while pulling one wire 11 along the outer circumferential surface of the root ball 4 with half-split logs 14 interposed between the wire 11 and four predetermined positions of the root ball 4, The wire 11 is sequentially hooked onto the pulley 1o attached to the support 8 and the pulley 13 rotatably attached to one side of the anchor 12 previously driven into the planting hole 2 as shown in FIG. Attach both ends 11a and llb with clips.

In this way, by pulling the wire 11 and turning the pulleys 10.13 of the support 8 and the anchor 12, the tension of the wire 11 is maintained constant, and the tension securely holds the root 3 of the tree 1. It will be supported by.

In addition, this fastening, as shown in Figure 3 (c) and (d),
A substantially U-shaped support 21 having a threaded portion 20, and two nuts 22, 22 that can be screwed into the threaded portion 20 of the support 21.
25. This is done using a stopper 24 consisting of a presser 23 that presses the wire 11 while being tightened by the wire 11. . . . indicates a total of four guide pieces, two on the front and rear sides of the presser 23, which are vertically installed downward to guide the wire 11.

After supporting the root portion 3 of the tree 1 in this manner, the construction for supporting the tree 1 is completed by filling the planting hole 2 with earth and sand as shown in FIG. In this case, the support 8, wire 6, and anchor 12 for supporting the root portion 3 of the tree 1 were all supported within the planting hole 2;
By filling the planting hole 2, these supports 8, wires 6, and anchors 12 are all finally buried underground. Therefore, the state of the tree support construction is not exposed on the ground, resulting in a significantly better external appearance.

Incidentally, when the roots of the tree l grow, the wire 11
It is necessary to loosen the tension of the wire 11, but this wire 11 consists of only one piece, and both ends 11a and llb of the wire 11 are connected to the above-mentioned stop 2.
4, the tension of the wire 11 can be arbitrarily adjusted according to the growth of the roots by attaching and detaching only the fixed ends 11a and llb, and the tension can be adjusted as desired. This work can be done very easily. Note that both ends 11a of the wire 11,
To attach and detach the llb, tighten the nut 22 of the stopper 24,
Or it can be done by loosening it.

To explain more specifically, both ends 11 of this wire 11
Adjustment of the tension by attaching and detaching a, llb is performed approximately every year, and after approximately 3 to 5 years, the roots have grown significantly and the tree 1 is supported only by the grown roots. Therefore, since the wire 11 does not need to be supported by tension, the wire 11 has both ends 11a, l
lb has been removed and will be extracted as is. Even in this case, since the wire 11 is composed of only one piece and is fixed at only one place by the fastener 24, the work of extracting it can be performed very easily.

Furthermore, due to changes over time, not only the roots of the tree l but also the trunk simultaneously grow and become thicker, and the wire 6 in the support 8 that is fitted around the root 3 at the lowest end of the trunk also grows at both ends 6a, 6.
b is fixed with a clip, the tightening force of the support body 8 can be freely adjusted according to the increase in thickness due to the growth of the root part 3 by attaching and detaching both ends 6a and 6b as shown in FIG. It is.

Incidentally, in the above embodiment, since the wire 11 consisting of only one wire fixed by clips at both ends 11a and llb was used, the above-mentioned preferable effect was obtained.
The number of wires 11 is by no means limited to one; for example, four wires may be used as shown in FIG. 6. That is, in the embodiment shown in FIG. 6, one support 8 has four pulleys 10.
... is attached, and four wires 11 are wound around each of the pulleys 1O1....

Further, in this embodiment, the pulley 10. . . . The hanging is made by using a wire 11 as a string material to be turned, but the type of string material is by no means limited to this wire 11, and the material of the string material is also not limited.

Furthermore, as is clear from the embodiment shown in FIG. 6 above, the number of supports 8 is not critical, and the structure thereof is similar to the above embodiments in which a rubber hose 7 is fitted onto the wire 6. Not limited. In short, it is sufficient that it is configured so that it can be fitted externally to the root portion 3 of the tree 1.

Furthermore, in this embodiment, the bottom wall surface 15 of the planting hole 2 is attached to the anchor 12.
That is, the anchor 12 is driven downward, but the driving direction of the anchor 12 is by no means limited to this, and it may be driven into the side wall surface of the planting hole 2, that is, in the lateral direction.

Furthermore, in this embodiment, a hemp net-like belt 5 is wrapped between the support 8 and the root portion 3 of the tree l, so that the root portion 3
Although the favorable effect of preventing damage to the
Wrapping band 5 is never a condition.

Furthermore, in the embodiment described above, the wire 11 is connected to the support 8 by attaching a pulley 13 to the tip of the support 8 and hooking and turning the wire 11 to the pulley 13. Although a favorable advantage has been obtained in that hanging on the wire 11 can be carried out very easily by removing the pulley 13 while transferring it, the means for connecting the wire 11 and the support body 8 is by no means limited to this.

Furthermore, in this embodiment, since the log 14 is interposed between the wire 11 and the root ball 4, the wire 11 is prevented from digging into the root ball 4 excessively, thereby preventing cracks and damage to the root ball 4. Although a favorable effect was obtained, the interposition of logs 14 is also not a condition.

In addition, it is also possible to replace this log 14 with an inclusion made of another material between the wire 11 and the root ball 4.

Furthermore, the type of fixing member driven into the inner wall surface of the planting hole 2 is not limited to the anchor 12 as in the embodiment, but may also be a wooden stake, etc., and the material, shape, etc. of the fixing member, Dimensions etc. do not matter.

In short, any material that can be driven into the ground is sufficient.

Furthermore, there is no question about the procedure for driving the fixing member, and it may be done either before or after the support body 8 is fitted around the root of the tree l. Later, the fixing member may be driven in while pulling the string material.

(Effects of the Invention) As described above, the present invention utilizes the tension of the string material connected to the support body fitted around the root of the tree and the fixing member driven into the inner wall surface of the planting hole. Since this is a method in which the root of the tree is supported underground, there is no need for pillars, etc., which are required in the conventional method of supporting the trunk of the tree. All of these components will be buried underground, and their supporting construction will not be exposed on the ground as in the past, so this has the particularly remarkable effect of significantly improving the appearance of the tree. I came to have it.

In particular, such artificially planted trees are generally planted in parks and other places where aesthetic appearance is required, so as mentioned above, supporting construction materials are buried underground, and the construction state Because the trees are not exposed on the ground, they do not spoil the beauty of the surrounding area where the trees are planted, and they do not give the impression that they have been planted artificially.
For example, it has practical benefits that can be widely used at exhibitions, amusement parks, tourist spots, etc.

In addition, when using a string material consisting of only one piece with both ends clipped, the tension of the string material can be freely adjusted according to the growth of the tree roots by attaching and detaching only the one clipped part. This has the effect that the tension can be adjusted very easily.
