Description

Description: TECHNICAL FIELD The present invention relates to a tree supporting construction method for constructing a tree while artificially planting it in a park, pavement, or other exhibition site.

(Prior Art) Conventionally, for example, there is a construction means shown in FIG. 10 as a means for supporting a tree. That is, the same means is the root pot provided at the root of the tree 51 in the planting hole 50 formed in the ground 49 in advance.
53 is stored, and after that, the root part of the tree 51 and the planting hole in advance
A plurality of anchors 55 driven into 50 are connected to a single tensioning wire 56 via two winches 52,
The winch 52 is operated to tension the wire 56, and the root of the tree 51 and the root pot are tensioned by the tension of the tensioned wire 56.
53 is fixed, and after that, the planting hole 37 is closed by putting soil or the like into the planting hole 37.

(Problems to be Solved by the Invention) In the above-mentioned conventional construction means, when the tensioning wire is stretched, two winches 52 are arranged on the upper surface of the root bowl 5 and in the radial direction, and these winches are arranged. The wire between the tree 3 and the anchor 55 is used to vertically stand the tree 3 by the 52.
56 length and tension are adjusted.

However, since the above-mentioned conventional means only arranges the two winches 52 in the radial direction of the root pot 5, the winch 52 allows the wire in the direction perpendicular to the direction in which the winches are provided.
The tension adjustment of 56 is impossible. Further, when the wire 56 is tightened by the winch 52, the vicinity of each winch 52 of the wire 56 can be tightened, but the wire 56 between the tree 3 and the anchor 7 where the winch 52 is not provided cannot be sufficiently tightened. there were.

Furthermore, in consideration of workability, each winch 52 is positioned on the upper surface of the root bowl 5, but it is very troublesome to position each winch 52 at a predetermined position in the connecting work of the wires 56, It took skill to support and construct the tree 51.

Further, when the wire 56 that has been strained with the passage of time loosens, the tightening work is performed, but in this case, since the wire 56 is wound with the winch 52, the winch 52 is the root bowl 5.
On the other hand, it may move to that side. As a result, soil and the like on the side portion of the root pot 5 must be dug up, and the tightening work on the side portion of the root pot 5 is complicated and difficult.

In view of the above problems, the present invention makes it possible to evenly tension the wire, and can easily support and construct trees without requiring skill, and moreover, perform retightening work of the wire easily and quickly. The challenge is to be able to do so.

(Means for Solving the Problems) The present invention has been made to solve the above problems,
The means for solving the problem is to store the root part of the tree 3 and the root pot 5 in the planting hole 37 formed in the ground 1 in advance,
Next, a tensioning wire 8 is connected to the root of the tree 3 and a plurality of anchors 7 fixed to the ground 1 in advance, and the wire 8 is tensioned by a winch 12, whereby the root of the tree 3 and After fixing the root pot 5, the planting hole 37 is closed with soil or the like and the root portion of the tree 3 is buried in the ground to support the tree 3. After connecting a plurality of winches 12 so as to be located on the upper surface of the root bowl 5, and further radially connecting separate tensioning wires 8 to each winch 12 and each anchor 7, each winch 12 is connected. Operate each wire 8
Is to fix the root part of the tree 3 by straining.

(Operation) In the present invention configured as described above, the root portion of the tree 3 housed in the planting hole 37 and each anchor 7 are connected by each wire 8 via each winch 12. After connecting the wires 8, each of the radially connected wires 8 is tensioned. However, since the winch 12 is provided in accordance with each wire 8, the tension of each wire 8 is increased through each winch 12. It is possible to easily stand and support the tree 3 vertically while adjusting.

If the wire 8 loosens after the construction of the tree 3, the winches 12 do not move to the side surface of the root pot 5 on the upper surface of the root pot 5 and connected to the tree 3, so The ground 1 can be dug up to the extent of being exposed, and the winch 12 can be appropriately operated on the upper surface of the root bowl 5 to further tighten it, and the operation can be performed easily and quickly.

Furthermore, when the wire 8 is stretched, the connector 13
The pressing body 26 is pressed against the surface of the tree 3 and the upper surface of the root pot 5, and the connector 13 is securely attached to the tree 3 side without rattling.

As shown in FIG. 5, 7 are anchors arranged at four positions on the side of the root pot 5 to support the root portion of the tree 3. Each anchor 7 is radially connected and tensioned by the tensioning wire 8 It is connected to the tree 3 via. Each anchor 7 is first
As shown in the figure, the anchor body 10 consisting of a rectangular flat plate
And a wire connecting portion 11 which is connected to the anchor body 10 at both ends and is formed by bending two wires upward. The length of one side of the anchor body 10 is approximately 35 cm.
Is set to.

A winch 12 for tensioning the wire 8 is provided corresponding to each anchor 7. That is, as shown in FIG. 1, each winch 12 is connected to the tree 3 via a connecting tool 13 and a base portion 14a connected to the connecting tool 13 by a vertical bolt 23 and extending upward from the base portion 14a. A pair of left and right plate-shaped frames 14, a roll 15 that is rotatably supported by the plate-shaped frame 14, and a pawl body 18 that is disengageably engaged with a ratchet 17 provided at one end of the roll 15. Have The ratchet 17 and the pawl 18 constitute a ratchet mechanism.

Then, one end 8a of the wire 8 connected to the connecting portion 11 of the anchor 7 is detachably connected to one plate-shaped frame 14 via a locking bolt 20. Also, the wire 8
The other end 8b is inserted into the insertion hole 21 formed in the roll 15 and is provided so as to be wound by rotating the roll 15.

The connector 13 includes a pair of left and right connector bodies 24 in which a rubber roller 26 is axially supported by a lateral support shaft 27, and a pair of upper and lower support pieces 25 for supporting a bolt 23 inserted into a base portion 14a of the winch 12. And the connector main body 24 and the support piece 25 are formed by bending a single metal plate.

29 is an opening formed in the main body 24 of each of the connecting tools 13, and a fastening belt for connecting each connecting tool 13 to the tree 3 is provided in the opening 29.
31 is inserted. Both ends of the belt 31 are connected to a fastener 35, and when the belt 31 is tightened by the fastener 35, the rollers 26 of each connector 13 are pressed against the upper surfaces of the tree 3 and the root pot 5. There is.

Next, a case where the tree 3 is supported and constructed in the above configuration will be described.

First, the planting hole 37 is formed in the ground 1 in advance. The planting hole 37 is formed slightly deeper so that the root pot 5 and the anchor 7 can be housed by a dedicated civil engineering machine (for example, a backhoe). Keep it. Then, the anchors 7 are arranged in the planting holes 37 so as to be located outside the outer peripheral surface of the root pot 5 (see FIG. 2), and the anchor body 10 of each anchor 7 is completely embedded, and , So that the upper part of the connecting part 11 is exposed.
Fill with dirt and sand. When the anchor main body 10 is embedded, the anchor main body 10 is reliably fixed by the sand and the like on its upper part, and its upward movement is prevented.

Next, the root pot 5 of the tree 3 is placed on the earth and sand or the like to which the anchor 7 is fixed and stored in the planting hole 37.

Further, the belt 31 is inserted into the opening 29 of each connecting tool 13 connected to the winch 12, and the belt 31 is wound around the root of the tree 3,
Both ends thereof are tightened by tightening the fasteners 35. When the belt 31 is tensioned, the roller 26 of the connecting tool 13 is pressed against the upper surfaces of the tree 3 and the root pot 5, so that each connecting tool 13 is connected to the tree 3.
Also, the root pot 5 can be securely fixed without rattling.

The connecting tools 13 and the winches 12 may be attached to the tree 3 side before the tree 3 is housed in the hole 37.

Thus, with the anchor body 10 fixed, the wires 8 are inserted into the connecting portions 11 of the anchors 7, respectively, and one end 8a of the wire 8 is fixed to the frame 14 of the connecting tool 13 via the locking bolt 20. Link.

Further, when the other end 8b side of each wire 8 is inserted into the insertion hole 21 of the roll 15 of the coupling tool 13 and then the roll 15 is rotated,
Since the anchor 7 is fixed, the wire 8 is wound on the other end 8b side and becomes in a tension state (see FIG. 3).
In this way, when the wire 8 is tensioned, the winch 12
Is provided in accordance with each anchor 7, it is possible to easily stand and support the tree 3 vertically while adjusting the tension of each wire 8 via each winch 12. In addition, the wire 8 is provided with a ratchet mechanism so that the pawl 18
As long as you don't release the ratchet 17's bite, it will not accidentally loosen. Reference numeral 41 is a protective pad provided between each wire 8 and the shoulder portion 5a of the root pot 5 to protect the root pot 5.

After tensioning each wire 8, the soil and the like are further put in the planting hole 37, the connector 13 and the winch 12 and the like are buried, and the planting hole 37 is closed to complete the support construction of the tree 3.

In the above embodiment, the wire 8 has a winch at one end.
12 is removable via bolt 20 and the other end is a roll
When the wire 8 becomes defective due to corrosion or the like, the defective wire 8 is removed from the winch 12 and only the wire 8 is replaced.
Etc. can be used as they are and are very economical.

Furthermore, after supporting and constructing the tree 3, the wire 8 changes with time.
Each winch 12 has a root bowl 5
Since it is provided on the upper surface of the winch 12, it is sufficient to dig the ground 1 to the extent that the winch 12 is exposed and operate the winch 12 to tighten it further, and the work can be easily performed.

Further, in the work of forming the planting hole 37, as compared with the construction means for driving the anchor as shown in the conventional example, the anchor body 10
The planting hole 37 has to be formed somewhat deeper by the amount of the burial, but since the planting hole 37 is excavated by the backhoe, there is no labor disadvantage and no increase in the working process.

Further, the method for supporting and constructing trees is not limited to the above embodiment, and may be as shown in FIGS. 8 and 9.

That is, the root portion of the tree 3 and the root pot 5 are housed in the planting hole 37, and each winch 12 is attached to the tree 3 via the belt 31. Next, the anchors 7 are arranged on the sides of the root pot 5 and at the positions where the winches 12 are provided (see FIG. 8), and the anchor body 10 of each anchor 7 is completely embedded and the connecting portion
Sediment or the like is put in the planting hole 37 so that the upper part of 11 is exposed, and then the wire 8 is connected to the connecting portion 11 and the winch 12 and tensioned in the same manner as in the above embodiment (see FIG. 9). .

Furthermore, it goes without saying that, as shown in the conventional example, a construction method of driving an anchor can also be adopted.

The anchor 7 is not limited to the one in the above embodiment, and for example, as shown in FIG. 7, a wire connecting portion 11 is provided from a single wire, and one end of the anchor 7 is located in the center of the anchor body 10. It is also possible to provide a connecting body 39 which is connected to the other part and through which the wire 8 is inserted at the other end, or
The wire connecting portion 11 may be formed of a plate-shaped body.

Further, the shape of the anchor body 10 is not limited to the rectangular shape, but may be formed in a triangular shape, a circular shape, or the like as shown by an imaginary line in FIG. 7, and its shape and size can be arbitrarily changed in design. Is.

In addition, the wire 8 refers to a linear wire such as a rope or a string, and the material thereof is not limited. Also,
The numbers of wires and anchors are not limited to those in the above embodiment.

(Effect of the invention) As described above, according to the present invention, since a plurality of winches connected to a tree are radially connected with separate tensioning wires, each winch is operated to tension each wire. The length and tension of the wire can be adjusted by using the winch at a desired position.

As a result, a tree inclined in any direction can be easily erected vertically by tightening the wire with a winch at a predetermined position.

Furthermore, since each winch is connected to the tree side,
It is not necessary to position the winch when connecting the wires as in the conventional case, and the worker can perform the tree supporting work very easily and quickly without requiring skill.

Further, since each wire is connected to the winch, there is an advantage that all the wires can be stretched with a predetermined tension and each wire can be evenly tensioned.

Moreover, if the wire becomes loose after supporting the tree,
Since each winch does not move on the upper surface of the root pot and on the side of the root pot by being connected to the tree, dig up the ground again to the extent that the winch is exposed, and operate the winch on the upper surface of the root pot to tighten it properly. Therefore, the work can be performed easily and quickly.
