The wire 14 is connected to the wire and the tree is supported by the tightening force of the wire 14.

[0004]

However, in the above-mentioned conventional method, since the root mortar is supported and fixed only by the vertical tightening force of the wire 14, the wire 14 may be loosened due to land subsidence or the like. However, there is a problem in that the tightening force for the root mortar may be impaired.

In addition, since an expandable anchor 13 as shown in FIG. 1 is used as a member for driving the ground, a special tool and a skill are required for handling such an anchor. And such anchors are not inexpensive.

In addition, since the upper surface of the root mortar 2a is fixed by the holding member 12, there is a disadvantage that the whole apparatus becomes large and the cost becomes large.

The present invention has been made in order to solve the above-mentioned problems. Therefore, even if the situation around the root pot is changed due to land subsidence or the like, the tightening force on the root pot is not impaired, and the driving operation of the driving member is made easy. Another object of the present invention is to reduce the cost of members used for supporting construction of trees.

Embodiments of the present invention will be described below with reference to the drawings.

First, as shown in FIG. 1, a root pot 2 of a tree is stored in a planting hole 1 formed in advance, and the root pot 2 is placed on a bottom wall 3 thereof.

Next, as shown in FIG.
Is wound around the belt-shaped winding device 5. However, the winding device 5 is loosely wound so as not to directly contact the root portion 4 of the tree 3.

The winding device 5 is made of a material that decomposes over time, such as hemp, cotton, jute, straw, paper, wool,
Materials such as silk, leather, wood, and palm can be used.

Next, as shown in FIG. 3, a shoulder pad 6 is set on the shoulder of the root mortar 2 and the substantially L-shaped angle 7 is brought into contact with the peripheral side surface of the root mortar 2 while the bottom wall 3 is kept. Type in.

The angle 7 has an elongated substantially L-shaped mounting portion 8 formed outside the upper portion thereof.
When the is driven into the ground with a vibrator or the like (not shown), a mounting portion 9 having a substantially circular plane is formed as a mounting portion of an attachment (not shown).

Next, as shown in FIG. 4, a bridging material 10 made of a belt-like synthetic fiber is bound to one of the winding devices 5 and the other is hung on the mounting portion 8 of the angle 7. Stop and attach.

Further, a winch 11 is attached to a predetermined position of the bridging member 10.

As shown in FIGS. 5 and 6, the installation of the shoulder pad 6, the driving of the angle 7, and the bridging of the bridging material 10 to the winding device 5 and the angle 7 are performed as shown in FIGS. Do it in place.

That is, the four bridging members 10,...
On the above, it is wound over the winding device 5 and the angle 7 at substantially equal intervals.

Then, by tightening with the winch 11, a tightening force is generated in each of the bridging members 10,..., Thereby fixing the root mortar 2.

In this case, since the bridging material 10 is hung on the mounting portion 8 located outside the upper portion of the angle 7, when the bridging material 10 is tightened by the winch 11, the bridging material 10 becomes as shown in FIGS. As shown in FIG.

On the other hand, the angle is driven into the bottom wall 3 of the planting hole 1 while being in contact with the peripheral side surface of the root pot 2.

Accordingly, when a tightening force is generated in the bridging member 10 by the tightening of the winch 11 as described above, the tightening force is generated in an oblique direction, and as a result, the tightening force is generated when the driven angle 7 is pulled out. Not only acts vertically but also acts laterally as a pressing force that presses the angle 7 inward against the root mortar 2, and the tightening force acts in both directions. The stability of the fixing of the root mortar and the supporting construction of the tree can be much better than before.

Thereafter, soil is put into the planting hole 1 and closed, thereby completing the tree supporting work.

In the above embodiment, since the winding device 5 is made of a decomposable material, a favorable effect that the winding device 5 can be disassembled after a predetermined number of years has been obtained is obtained.
It is not an essential condition of the present invention that the winding device 5 is made of a decomposable material.

In this embodiment, since the winding device 5 is formed in a plate belt shape, the operation of binding the ends of the winding device can be easily performed. It took a considerable time for the water to soak up, and a favorable effect of increasing the time required for decomposition due to rot caused by water was obtained, but the shape of the winding device 5 is not limited to this. .

Further, in this embodiment, the angle 7 is driven into the ground in a state where the angle 7 is in contact with the peripheral side surface of the root pot 2.
It is not always necessary to drive the angle 7 into contact with the peripheral side surface of the root mortar 2, for example, after driving the angle 7 into the ground away from the peripheral side surface of the root mortar 2, It is also possible to put soil between the sides and fix it.

Even in this case, the pull-out resistance acting on the angle 7 by the tightening force generated in the bridging material 10 is transmitted through the soil between the angle 7 and the peripheral side surface of the root mortar 2 after the angle 7 is driven. The angle 7 is in contact with the peripheral side surface of the root mortar 2 as in the above embodiment, in that the angle 7 acts as a pressing force on the side of the root mortar 2, and thus the tightening force is converted into a force acting in both directions of the angle 7. It is common to the case.

Therefore, the angle 7 only needs to be driven into the ground along the peripheral side surface of the root mortar 2. Here, "along the peripheral side surface of the root mortar 2" means that the root mortar 2
In addition to the case where the angle 7 is driven into the ground while being in contact with the peripheral side surface, the angle 7 is driven into the ground while being separated from the peripheral side surface of the root mortar 2, and then the angle 7 and the root mortar 2
This includes the case where soil is inserted between the peripheral side surfaces and fixed.

Further, in this embodiment, the angle 7 is formed to have a substantially L-shaped cross section. However, the shape of the angle 7 is not limited to this. It is sufficient if it is formed in

Further, in the present embodiment, the elongated approximately L-shaped mounting portion 8 is formed outside the upper portion of the angle 7, and the bridging material 10 is hung on the mounting portion 8. Lumber 10
The structure for attaching to the angle 7 is not limited to this.

In this embodiment, since the attachment portion 9 for the attachment for the vibrator is formed above the angle 7, the attachment is attached to the attachment portion 9.
Further, by attaching a vibrator to the attachment, a favorable effect that the angle 7 can be easily driven into the ground using the vibration of the vibrator was obtained, but it is also possible to form such a mounting portion 9. It is not a necessary condition for the invention.

Therefore, the angle 7 can be driven by a hammer or the like without using such a vibrator.

Further, in the above embodiment, the bridging material 10 bridging between the winding device 5 and the angle 7 is formed in a belt shape.
The shape of the bridging material 10 is not limited to this, and may be, for example, a string-like shape. In other words, if the bridging material 10 can be bridging between the winding device 5 and the angle 7, its shape is Don't ask.

Further, the material of the bridging member 10 is not limited to the synthetic fiber of this embodiment, but may be a metal member, for example.

Further, in the above embodiment, the shoulder pad 6 is provided on the shoulder of the root mortar 2, so that a favorable effect that damage to the shoulder of the root mortar 2 can be suitably prevented is obtained. The installation of the pad 6 is not an essential condition for the present invention.

Further, in the above-described embodiment, the bridging material 10 is laid over the winding device 5 and the angle 7, but is not limited to this.
For example, as shown in FIG.
The root mortar 2 may be fixed such that a string-like bridging material 10 is laid.

Further, as shown in FIG. 8, it is also possible to fix the root mortar 2 by bridging the bridging material 10 between the adjacent angles 7,7.

In any case, in the embodiment shown in FIGS. 7 and 8, since the bridging member 10 is bridged between the angles 7, 7, the winding device 5 around the tree is unnecessary. Therefore, the winding device 5 is not an essential condition for the present invention.

Further, the procedure for installing the winding device 5, the shoulder pad 6, the angle 7, and the bridging member 10 is not limited to the above embodiment, and can be arbitrarily changed.

Further, in the above embodiment, the case where the root pot 2 is housed in the planting hole 1 formed in advance on the general ground and the tree is supported and constructed has been described. It is also possible to apply the present invention to support construction of trees on artificial ground. In the case of using such an artificial ground, it is not necessary to form the planting hole 1, and it is possible to support the tree by stacking the artificial soil so that the root pot 2 is buried.

[0047]

As described above, the present invention removes the bridging material.
The implantation member having an attachment portion for attaching, implanted on the ground surface along the peripheral surface of the root pots trees, and the該根pots hung a KaWataru material, the rack passes material into the mounting portion of the hammering member Install,
When a tightening force is applied to the bridging material, the bridging material takes up the driving member.
Is stretched obliquely toward the biasing portion side, since they are constructed as pull-out resistance force may occur against the pressing force and the ground to the root ball-side in the driving member, the tightening force by the rack passes material obliquely One
As a result, the tightening force acts not only in a vertical direction as a resistance force against pulling out of the driven driving member, but also a pressing force for pressing the driving member inward against the root mortar. As it acts in the lateral direction as well, the tightening force is converted into such a force acting in both directions, and the fixing of the root mortar, and thus the stability of the tree supporting construction is much better than before. It has become.

Further, since a driving member such as an angle having high versatility can be used as a driving member for driving along the peripheral side surface of the root mortar, there is no cost as in a conventional expanding anchor. In addition, there is an effect that the operation can be performed by a simple operation of merely driving without requiring a special tool for driving.
