DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for supporting construction of a tree and a mounting body for a root pot used in the method for supporting and constructing the tree. The present invention relates to a method for supporting a tree to be constructed while supporting a tree to be planted, and a mounting body for a root pot used for mounting a root pot in the method for supporting and supporting a tree.

[0002]

2. Description of the Related Art Conventionally, as a prior art similar to the present invention, there is a method of supporting and supporting a tree described in Japanese Patent Application Laid-Open No. 63-87919 by the present applicant.

[0003] That is, in this supporting construction method, as shown in FIG. 8, first, a root pot 14 is housed in a planting hole 3 formed in advance on the ground, and a root wire 22 is attached to the root of a tree 15.
And the extension wire 16 hung on the root wire 22 is wrapped around the root bowl 14, and is hung on the anchor 23 driven into the bottom wall surface 4 of the planting hole 3. By the winch 24 interposed in the wire 16,
In this method, tension is applied to the wire 16 to support and fix the tree as a whole.

[0004]

However, the above-described conventional method has the following problems.
That is, the anchor 2 driven into the bottom wall 4 of the planting hole 3
3 has two anchor resistance plates 25 that can be opened outwardly, and although the driving is stably ensured, its resistance to external force, especially external force in the longitudinal direction of the anchor is low. Therefore, in a construction site where the supporting ground is soft, such as a new landfill or a site where garbage is accumulated, there is a problem in particular in resistance.

[0005] On the other hand, as another prior art similar to the present invention, there is a tree supporting method described in Japanese Patent Application Laid-Open No. Hei 3-236727.

[0006] That is, in this supporting construction method, the root pot mounting body 6c for mounting the root pot is installed on the bottom wall surface 4 of the planting hole 3, and the central space of the root pot mounting body 6c is provided. A pile 27 is cast on the bottom wall surface 4 via the portion 26, and the root mortar 14 is placed on the root mortar mounting body 6c, and a string 16c is wrapped around the root mortar 14 to remove trees. It is to be supported.

However, in such a supporting construction method, the root mortar 14 is mounted on the mounting body 6c for the root mortar. It will depend on the size of the mounting body 6c, and therefore, the size of the root mortar 14 used for construction will also be limited,
If the size of the root mortar 14 changes, it is required to change the root mortar mounting body 6c.

[0008] Further, since the dimensions of the root mortar mounting body 6c are determined, when mounting the root mortar 14 according to this dimension, an improving agent is placed on the back side of the root mortar mounting body 14. In other words, there is a problem that the sheet resistance cannot be obtained and the tree may fall.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a method for supporting a tree and a method for supporting a tree in the supporting construction. feature of the method is the solid Teikarada 7 to the moving body movably mounted and the resistor 12 is set kicked by the movable body
The root mortar 14 is placed on the root mortar mounting body 6 configured by
Next, the string material is wrapped around the root pot 14 and the end of the string material is attached to the mounting body 6 for the root pot, so that the root of the tree 15 is supported and constructed.

A feature of the mortar mount 6 for supporting the tree is that the mortar 14 is used by mounting the mortar 14 at the time of supporting the tree. 7, a movable body is movably attached to the movable body and a resistor 12
Is provided .

[0011]

In other words, when the string material is stretched for such a tree supporting construction method, the string material is inserted between the root wall 3 and the bottom wall surface of the planting hole 4. Since it is hung around the mounting body 6 for the root, the mounting body 6 for the root pot and the root
It is connected and fixed in tension by the tension generated in the cord material.

Further, since the moving body is movably mounted on the fixed body 7, the moving body is fixed to the fixed body 7.
, The size of the mounting body for root mortar 6 can be freely adjusted according to the size of the root mortar.

In addition, the size of the mounting body 6 for the root
If it is adjusted to be slightly larger than the size of 4, the moment increases, and the resistance to the force of the tree to fall over increases accordingly.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. First, a description will be given of a configuration of the mounting body 6 for a root pot in a tree supporting operation as one embodiment. As shown in FIG. 2 and FIG. With respect to the fixed body 7 composed of the frame rod 8 and the crossing rod 9 that crosses the corner of the frame rod 8 diagonally,
A slide rod 10 as a moving body is movably mounted. More specifically, a total of four slide rods 10 are slidably inserted into the ends of the intersecting rods 9 of the fixed body 7, and the slide rods 10 are movable with respect to the mounting body 7. ing.

[0015] Then, the upper surface side of the distal end portion 10a of the slide rod 10 is Dakomi杆11 is fixed, planar pentagonal resistor 12 is fixed to the lower surface side.

Next, a description will be given of an embodiment of a supporting construction method for supporting and constructing a tree by using the above-described root pot mounting body 6.

First, as shown in FIG. 1, the ground, in particular, the upper layer 1 is relatively stable and firm, but the lower layer 2 is formed in advance on a construction site that is soft due to accumulation of dust and the like. As shown in FIG. 2, a soil conditioner 5 is sprayed on the bottom wall surface 4 of the planting hole 3, and a root pot mounting body 6 is mounted on the soil improving agent 5.

Next, the four slide rods 10,... Of the above-mentioned root pot mounting body 6 are respectively peeled off and slid, so that the entire mounting body 6 is expanded. The four driving rods 11,... Fixed to the upper surface of the distal end portion 10a are driven into the inner wall surface 13 of the planting hole 3, respectively.

After the driving rods 11,... Have been driven in as described above and the mounting body 6 for root mortar has been fixed, as shown in FIG. Is placed.

Next, as shown in FIG. 6, a tension wire 16 is hung on the base of the tree 15 and the mounting body 7 (more specifically, the base of the slide rod 10) substantially immediately below the root pot 14. turn.

At this time, as shown in FIG. 6, a protection pad 17 is attached to the shoulder of the root mortar 14 in order to protect the root mortar 14 from biting of the stretching wire 16 into the root mortar 14.

The root of the tree 15 and the wire for tensioning 1
The connection with No. 6 will be described in more detail below.

That is, as shown in FIG.
A ring body 19 is wound around a root portion of the ring member through a net-like body 18, and the wire for extension 16 is hung on stoppers 20,... Attached to the ring body.

Thereafter, tension is applied to the tensioning wire 16 by the winch 21.

Then, the root 14 is supported by the tension, and the tension of the tensioning wire 16 also acts on the ring 19, and the ring 19 is pressed against the root of the tree 1. It will be done.

After supporting the root of the tree 1 in this way, soil or the like is buried in the planting hole 3. In this way, the park,
Even in a pavement, an exposition hall, or the like, especially in a construction site where the upper layer 1 is relatively stable and firm, but the lower layer 2 is soft due to accumulation of garbage, etc., the tree support construction can be performed stably and reliably. It is.

In the above-described embodiment, the procedure from the mounting of the mounting body 6 for root mortar, the sliding of the slide rod 10 and the driving of the driving rod 11 to the tensioning of the tensioning wire 16 is not necessarily the same. However, the present invention is not limited to this. That is, it is of course possible to appropriately change this procedure in consideration of workability and the like.

Further, in the above-described embodiment, the fixed body 7 is constituted by the frame rod 8 and the crossed rod 9 as the mounting body 6 for the root pot, but the structure of the fixed body 7 is such a rod (pipe). However, the present invention is not limited to the configuration described above, and may be, for example, a plate. In short, it is sufficient that the root pot 14 can be placed between the root pot 14 and the bottom wall surface 4 of the planting hole 3.

In the above embodiment, the slide rod 11 is slidably inserted into the end of the cross rod 9 so that the slide rod 11 as a movable body is movably attached to the fixed body 7. However, the means for enabling the moving body to move with respect to the fixed body 7 is not limited to the means by which the slide rod 11 slides. In short, it is only necessary that the movable body be movable with respect to the fixed body 7. Further, in this embodiment, the slide rod 11 as the moving body is fixed to the fixed body 7.
Although the moving body is formed separately from the moving body, the moving body is not necessarily required to be formed separately, and the moving body may be formed integrally with the fixed body 7.

In this embodiment, since the driving rod 11 is fixed to the upper surface of the distal end portion 10a of the sliding rod 10, the driving rod 11 is driven into the inner wall 13 of the planting hole 3 to mount the root pot. Although the preferable advantage that the installation body 6 can be reliably installed on the bottom wall surface 4 of the planting hole 3 without displacing the position is obtained, it is not possible to drive such a driving rod 11 into the inner wall surface 13 of the planting hole 3. It is not a necessary condition for the invention.

When the above-described fixing means using the driving rod is employed, the side wall surface (the inner wall surface 1) of the planting hole 3 as described above is used.
3) In addition to the fixing, the driving rod (anchor) for driving the bottom wall of the planting hole 3 is attached to the tip of the mounting body for the root pot, and fixed on both the side wall surface and the bottom wall surface of the planting hole 3. In this case, the root can be supported and fixed more reliably.

Furthermore, in the embodiment, although fixed planar pentagonal resistor 12 on the lower surface of the slide rod 10, the resistance
The shape of the body 12 is not limited to this. Also, slide rod
It may be formed integrally with a moving body such as 10.
No.

Further, in this embodiment, a wire is used as a cord material for tensioning, rooting, etc., but it is not limited to this if it is flexible and firm and has a predetermined corrosion resistance and workability. Not something. The material is not limited to metal, synthetic resin, and the like. The point is that any material that can be wrapped around the root mortar 14 and whose end can be attached to the root mortar mounting body 6 may be used.

Further, in this embodiment, a tension wire 16 serving as a string material is attached to the root of the tree 15 and the fixed body 7 (more specifically, the root of the slide rod 10) substantially directly below the root pot 14.
However, the position at which the end of the cord is attached is not limited to this, but the point is that the end of the cord is attached to the fixed body 7.

Further, in the above-described embodiment, the case where the root pot 14 is housed in the planting hole 3 formed in advance on the general ground to support the tree is described. It is also possible to apply the present invention to support construction of trees on artificial ground. When used for such artificial ground, the formation of the planting hole 3 is not necessary, and the tree 15 can be supported and supported by stacking artificial soil so that the root pot 14 is buried.

Furthermore, in this embodiment, the case where the ground is constructed on a construction site where the ground is soft, such as the site of garbage accumulation, is particularly described. It goes without saying that it is also effective on the ground.

[0037]

As described above, according to the present invention, the movable body is movably attached to the fixed body, and the resistor 12 is attached to the movable body.
Provided by placing the root ball on a mounting body mounting for root pot that is configured,
Next, a string material is wrapped around the root mortar, and the end portion of the string material is attached to the mounting body for the root mortar, so that the root portion of the tree is supported and constructed. By moving the moving object with respect to the size of the root mortar mounting body can be set according to the size of the root mortar to be laid, therefore, trees having different root mortar sizes can be set. On the other hand, there is no need to prepare root mortar mounts of different dimensions, and there is an effect that one root mortar mount can be used for root mortars of different sizes.

Further, if the size of the mounting body is adjusted to be slightly larger than the size of the root mortar, the moment is increased, and accordingly, the resistance to the force of the tree to fall is increased. There is.

As a result, there is a real advantage that it can withstand a strong wind at a wind speed of about 60 m.

In addition, since the root pot is not placed directly on the bottom wall of the planting hole, but the root pot mounting body is interposed between the bottom wall and the root pot, construction is performed. There is an advantage that the construction can be performed irrespective of the strength, so that the invention can be applied to a construction site that is soft due to accumulation of dust and the like.

Further, when a driving rod is provided on the fixed body and the driving rod is driven into the wall surface of the planted hole, the fixed body is securely mounted on the bottom wall surface of the planted hole without displacement. As a result, it is possible to drive into the local board, and the supporting force is further improved, and even if an improving agent is interposed on the lower surface side of the mounting body, the surface resistance does not decrease and the sinking There is an effect that no intrusion occurs.

Further, since the resistor is provided on the movable body, there is an effect that the mounting body for the root pot can be stably mounted on the bottom wall surface of the planting hole.
