Supporting construction method of trees and supporting construction equipment

The present invention relates to a supporting construction method for trees and a supporting construction tool, and in particular to a supporting construction method and supporting construction tools relating to trees to be constructed as street trees.

In recent years, demands for urban greening and so on have risen, corresponding to various places in the urban area, such as parks, pedestrian walkways, exhibition halls, parking lots, shopping malls, plazas, and open space, etc. Construction method of trees. Moreover, in such a supporting processing method, it is necessary to fix the root basin of the tree in the underground portion, and various conventional methods and tools have been used for the supporting construction method and the supporting construction tool.

For example, a rope such as a copper wire is wrapped around the root basin, the rope is locked to a nailing member such as a fixture, and the method of nailing the component into the ground to fix the root basin is The 12th diagram of the prior art document 1 and the like) and the method of replacing the root body on the carrier, replacing the root basin around the carrier (the following reference documents 2, 3), or along The method of nailing the side of the root pot into the pile-shaped element (the following authorized documents 4, 5) and the like is used.

This method is mainly used in a place such as an exhibition hall, a shopping mall, a plaza, a public open space, etc., to support a high tree having a height of 3 m (meter) or more, and the construction method and the supporting tool for the construction method. Huge, and some degree of construction costs are required.

On the other hand, for example, trees that are planted as street trees, and the support of relatively small trees with a tree height of 3 m or less, the conventional method of using two-legged pillars made of round wood is still being used. However, when such a method of using a two-legged struts made of round wood is employed, the strength of supporting trees may not be sufficient.

The present invention is to solve the above problems, and provides a supporting construction method for trees and supporting construction tools, mainly because the construction method and the supporting construction tools are not as large as those used to support the construction trees with a height of more than 3 m, and These construction methods and supporting construction tools are cheaper, especially when used as support for construction of street trees, etc., and the support strength is more stable than the use of the conventional two-legged method made of round wood. And the cost is the same or cheaper than the method of using such a two-legged support.

In order to solve the above problems, the present invention provides a supporting construction method for a tree, characterized in that a laying sheet 1 is placed on a floor, and a susceptor 2 as a root basin 17 on which the tree 16 is placed is attached to the laying sheet 1 The root pot 17 is placed on the base 2, and the root pot pressing sheet 7 is placed on the upper surface of the root pot 17, and the base pot pressing sheet is fixed by the root pot pressing sheet fixing means. This support construction method is mainly applied to a so-called underground pillar that accommodates and supports the construction root pot 17 in the planting hole 15 previously formed in the ground. At this time, the laying sheet 1 is laid on the bottom wall surface 20 of the planting hole 15.

Moreover, the present invention provides a supporting tool for a tree, comprising: a laying sheet 1 laid on the floor, and a base for mounting the root basin 17 on the laying sheet 1 and mounting the tree 16. 2. The base pot pressing sheet 7 placed on the upper surface of the root pot 17 and the sheet pot pressing sheet fixing means for fixing the root pot pressing sheet.

The susceptor 2 attached to the laying sheet 1 is preferably fixed by a susceptor fixing means. For the susceptor fixing means, for example, one side is pressed from the upper side to the holding base 2 while being nailed to the ground. The base holder 4 and an article such as the base fixture 3 formed from the nailing body 5 that is locked to the base holder 4 and is deeper than the base holder 4 to the ground. Further, in the sheet body fixing means for root canal pressing, an article such as a binding string 18 which is bound by the sheet 7 for pressing the root basin and the base 2 to fix the root pot pressing sheet 7 is used.

In the present invention, as described above, the laying sheet is laid on the floor, and the base which is the root pot on which the tree is placed is attached to the base for laying the sheet, because the base pot is fixed by the sheet fixing means by the base pot pressing The construction of the sheet for pressing is stronger than the method of using the conventional two-legged struts made of round wood, and the cost is the same as that of the method of using such a two-legged struts. Support construction methods and supporting construction tools for cheaper trees.

For other purposes and functions of the present invention, please refer to the drawings and the embodiments, which are described in detail below.

As described above, in the supporting construction method of the tree of the present invention, the laying sheet is laid on the floor, and the base for mounting the tree is attached to the laying sheet, and the root basin is placed on the base. In the upper pot, the sheet for pressing the base pot is placed on the top of the root pot, and the sheet for pressing the pot is fixed by a sheet fixing means for root pot pressing.

As described above, the supporting method for supporting trees according to the present invention is a sheet for laying on the floor, and a pedestal as a root pot on which the trees are placed is attached to the sheet for laying, and the root pot is placed on the base. A method of placing the root pot pressing sheet on the top of the root pot and attaching and fixing the pot pressing sheet by the root pot pressing sheet fixing means.

The supporting construction method of the tree of the present invention is mainly applied to a supporting construction method of a tree mainly called an underground pillar. Therefore, the laying sheet is previously laid on the bottom wall surface of the planting hole formed on the ground. When the laying sheet is laid on the bottom wall surface of the planting hole, the pedestal can be attached to the laying sheet at the construction site, but the pedestal is preferably pre-installed from the viewpoint of easy construction and shortening of the construction time. On the laying sheet. The attachment to the susceptor on the sheet for laying may be carried out, for example, by adhesion of an adhesive or the like, but may be attached by other means.

Moreover, the supporting tool for a tree according to the present invention includes a laying sheet laid on the floor, a base which is attached to the laying sheet and has a root basin on which the tree is placed, and is placed on the base basin. The upper base pot pressing sheet and the sheet pot pressing sheet fixing means for fixing the root pot pressing sheet are configured.

The sheet for laying is laid on the ground, in particular, the bottom wall of the planting hole. Therefore, by burying the weight of the soil in the peripheral portion of the laid sheet to be laid, the initial stage contributes to the stability of the tree, and because For the sake of the sheet, the growth of the roots is not hindered by the long-term roots and the strength is maintained. The material of the sheet for laying is not particularly limited, but from the viewpoint of prevention of damage to the natural environment, it is preferable to use a decomposable material which can be decomposed by being buried in the soil. In terms of the decomposable material, for example, natural fibers such as coconut fiber, hemp, cotton, and jute, and rice straw, paper, and the like can be used, and among these, from the viewpoint of ease of handling and cost, it is preferred. It is made using coconut fiber and hemp.

Further, since the pedestal makes the static stability of the initial root basin good, it is used to prevent the root basin from being inadvertently displaced from the susceptor by rotation or the like as will be described later. The material of the pedestal is also not particularly limited, and it is preferred to use a wooden article. The use of a wooden base is the same as the laying of a sheet, because it can be decomposed after being buried in the soil for a certain number of years, thereby contributing to the prevention of damage to the natural environment. Moreover, making a wooden product can reduce the cost of the pedestal.

Although the shape of the susceptor is not particularly limited, it is preferably formed into a shape suitable for placing a root pot. For example, a frame-like object having a substantially square shape is formed on the four sides by using a frame member having a rectangular columnar shape. In order to use such a flat, square-shaped frame-shaped object, generally, the root basin with a circular shape is locked to the frame-shaped base and placed on the base, preventing the root basin from being constructed during construction. The position on the pedestal is inadvertently offset.

Moreover, the base can be fixed by means of a base fixing means. Although the susceptor fixing means is not particularly limited, for example, when a frame member in which a wooden substrate is placed on the four sides as described above is formed into a frame-like object having a substantially square shape, a straddle can be used. An element that is nailed into the ground by a frame element. More specifically, a pedestal holder that is held by the susceptor from the upper side and that is nailed to the ground, and a nail that is locked to the pedestal holder and that is deeper than the pedestal holder to the ground can be used. The base formed by the two elements of the body is fixed with a general object.

As described above, the susceptor 2 is attached to the laying sheet 1 by, for example, adhesive adhesion. However, the susceptor 2 is fixed by the above-described susceptor attachment means, and the susceptor 2 can be satisfactorily prevented. The susceptor 2 is inadvertently detached from the laying sheet 1 and floats. Further, the susceptor 2 may be attached to the laying sheet 1 by only the susceptor fixing means such as the susceptor fixing means 3, without using the attachment means such as the adhesive adhering. At this time, the susceptor fixing means itself becomes a means for attaching the susceptor 2 to the sheet 1 for laying.

The base bowl pressing sheet is used to fix the base pot from the upper side, but since it is a sheet, the whole root basin is pressed, and the biting into the root pot is small. In particular, since the base of a small tree is weak, it is effective to press the root-plate type with a sheet-like sheet member. The material of the sheet for pressing the base pot is also not particularly limited, and synthetic fibers and natural fibers can be used. From the viewpoint of preventing damage to the natural environment, it is preferable to use natural fibers such as hemp, cotton, coconut fiber, and jute, as in the above-mentioned laying sheet, but the base pressing sheet is pressed by the root basin. In the case where an external force such as a fastening force from the base plate pressing sheet fixing means occurs, it is preferable from the viewpoint of inadvertently tearing the sheet for preventing the base bowl pressing. Use strong synthetic fibers. In the case of synthetic fibers, articles such as polypropylene can be used in terms of versatility and cost.

In addition, for example, a sheet-like article such as a band for pressing a base of a root basin is bundled and fixed by a sheet for pressing the root basin and a base. When the strap is placed across the base pot pressing sheet and the base, for example, a hole for inserting the strap is inserted into the base pot pressing sheet, and a locking device for locking the strap is attached to the base. When the one end portion of the binding tape is locked to the locking device, the other end portion of the binding tape is inserted into the hole of the root basin pressing sheet, and the other end side of the binding tape inserted into the hole is wound back to be mounted. On the card holder side of the base, the other end of the strap is locked to the clip, and the strap is formed across the base pressing sheet and the base.

Such a strap is formed, for example, from the head and the abdomen, and has a hole in the head, and a distal end portion on the distal end side of the head is inserted into the hole in the head, and a strap that prevents movement in the opposite direction can be used. A strap with a backstop function. Such a strap is generally a strap called Insulok (registered trademark: manufactured by Hellermanntyton Co., Ltd.). Although the material of the binding tape is not particularly limited, for example, an article made of a synthetic resin such as polyamide (aliphatic polyamide) and polypropylene can be used. By using such a functional bundling belt having a reverse function, inadvertent detachment of the strap from the locking device can be satisfactorily prevented. Moreover, such a strap has the advantage that the work for bundling is simple, and the work can be performed in a short time without being slow or detached. However, instead of such a strap having a function of backstopping, a general rope-like body can be used.

In the case of the locking device that locks the strap, it is possible to use a locking body that is formed in a slightly S-shaped side from the above-described strap, and that can be inserted into the base while locking the locking body. An object formed by fixing two elements of the fixing body of the locking body.

Hereinafter, a more specific embodiment of the present invention will be described with reference to the drawings.

Therefore, the hole 6 of the slightly annular head portion 5a is formed in an inner diameter such that the upper pressing portion 4a of the susceptor holder 4 is insertable. Both the nailing body 5 and the susceptor holding body 4 are made of a metal such as iron.

As shown in Fig. 4, since the base pot pressing sheet 7 is formed in a flat square shape, the whole is composed of synthetic fibers formed of polypropylene. A circular tree insertion hole 8 through which a tree is inserted is inserted in the center of the root pot pressing sheet 7, and is connected to the tree insertion hole 8 to form a corner portion of the corner of the root basin pressing sheet 7 A slot 9 is provided. Further, in each of the three corner portions of the four corner portions of the base bowl pressing sheet 7, one insertion hole 10 for inserting a binding tape to be described later is inserted, and one of the insertion holes 10 facing the slit 9 is formed. At the corner portion, two insertion holes 10 are bored across the slits 9. The two insertion holes 10, 10 are pierced in an asymmetrical position with respect to the slit 9.

As shown in Fig. 5, the strap 18 has a head portion 18a wider than the abdomen 18b in the upper portion of the elongated abdomen 18b, and the lower end portion 18c of the lower portion of the abdomen 18b is formed into a sharp shape. In the head portion 18a of the binding belt 18, the lower end portion 18c is returned to the head portion 18a side to bend the abdomen 18b, and the hole into which the distal end portion 18c is inserted is inserted. Although the hole is allowed to be inserted into the distal end portion 18c in the insertion direction, the distal end portion 18c is preferably prevented from being pulled out in the opposite direction to the insertion direction, and has a function of backstopping. The strap 18 is entirely composed of polyamide.

As shown in Fig. 6, the locking device 11 is fixed by the locking body 12 in which the binding band 18 is locked, and the side surface is formed with a substantially S-shaped locking body 12 and the locking body 12 is locked while being inserted into the base 2. The fixed body 13 is formed. As shown in Fig. 6, the fixed body 13 is formed by a slightly annular head portion 13a and an abdomen 13b formed at a lower portion of the head portion 13a, and the front end portion 13c of the abdomen 13b is formed into a sharp shape. Therefore, the hole portion 14 of the slightly annular head portion 13a is formed into an inner diameter into which the above-described side S-shaped locking body 12 can be inserted. Both the locking body 12 and the fixed body 13 are made of a metal such as iron.

As shown in Fig. 7, the laying sheet 1 and the susceptor 2 are integrally molded in advance on the laying sheet 1 by adhering the susceptor 2 to an adhesive sheet or the like. Further, as shown in Fig. 8, the locking tool 11 is fixed to the four corner portions of the base 2 in advance and attached. More specifically, as shown in Fig. 9, the fixing body 13 formed with the locking tool 11 is driven into the base 2, and the locking body 12 is inserted into the hole portion 14 of the head portion 13a of the fixed body 13 The locking body 12 is locked to the fixed body 13, and the locking tool 11 is attached to the base 2.

As shown in FIG. 9, at this time, the fixed body 13 is attached by the operation of being nailed into the susceptor 2 in a state where only the head portion 13a is exposed and the abdomen 13b is completely embedded in the susceptor 2. Further, in the ninth diagram, in the drawings, the locking body 12 having a slightly S-shaped side is in a state of standing, but the locking body 12 is slidably locked with respect to the fixed body 13. Therefore, actually, the locking body 12 is mounted in a state of being laid flat with respect to the fixed body 13.

Next, a description will be given of a method of supporting the construction tool using the trees formed as described above and supporting the construction of the trees.

As shown in FIGS. 10 to 12, first, in the planting hole 15 formed in advance, the susceptor 2 houses the sheet 1 for laying, and the sheet for laying 1 is placed on the bottom wall surface 20 of the planting hole 15. As shown in Figs. 11 and 12, at this time, when the outer diameter of the laying sheet 1 is formed larger than the inner diameter of the planting hole 15, the end portion 1a of the laying sheet 1 is bent to the hole. 15 side wall surface 21 side. As described above, the locking tool 11 is previously mounted to the base 2.

Next, as shown in Figs. 13 to 15, four pedestal fixtures 3 are respectively attached to the corner posts 2a, 2b, 2c, 2d constituting the four sides of the susceptor 2. More specifically, as shown in Fig. 15, the upper pressing portion 4a of the susceptor holding body 4 is placed on the upper surface of the susceptor 2, and one of the pair of hanging portions 4b and 4b of the susceptor holding body 4 is suspended. The portion 4b is slightly separated from the side surface 7 of the base 2 from the side of the base 2 by the other hanging portion 4b, and the front end portions 4c, 4c of the two hanging portions 4b, 4b are nailed as shown in Figs. 16 and 17. The bottom wall surface 20 of the planting hole 15 is inserted. As shown in the same figure, the front end portions 4c and 4c of the susceptor holding members are passed through the laying sheet 1 and are driven into the bottom wall surface 2.

Therefore, the pedestal holder 4 is inserted into the hole portion 6 of the head portion 5a of the nailing body 5 from the side of the lower hanging portion 4b of the bottom wall surface 20 from the side surface of the susceptor 2, and the In the state shown in Fig. 16 and Fig. 17, the upper portion pressing portion 4a of the susceptor holding body 4 is inserted into the hole portion 6 of the head portion 5a of the nailing body 5, and the abdomen 5b of the driving body 5 is placed along the susceptor 2. On the side surface, the abdomen 5b and the front end portion 5c of the nailing body 5 are nailed into the bottom wall surface 20 of the planting hole 15. The distal portion of the driving body 5 _c 5 also holding the front end portion of the base member with the same 4c, through the laying of the sheet 1 is driven into the bottom wall surface 20.

At this time, the upper surface of the susceptor 2 is in contact with the upper pressing portion 4a of the susceptor holding body 4, and the front end portions 4c and 4c of the susceptor holding body 4 are nailed into the bottom wall surface 20 of the planting hole 15, and this is made further. The upper pressing portion 4a of the susceptor holding body 4 is inserted into the hole portion 6 of the head portion 5a of the nailing body 5, and the front end portion 5c of the nailing body 5 is nailed into the bottom wall surface 20 of the planting hole 15, so that the three front ends are When the portions 4c, 4c, and 5c are driven, the pressing force from the upper pressing portion 4a of the susceptor holding body 4 acts on the susceptor 2, and as a result, the susceptor 2 does not cause a positional shift, and is reliably fixed for laying. On sheet 1.

Next, as shown in Figs. 18 to 20, the root basin 17 of the tree 16 is placed on the susceptor 2. At this time, since the susceptor 2 is firmly and firmly fixed by the susceptor 3 formed by the susceptor holding body 4 and the nailing body 5 as described above, the pedestal is mounted on the base pot 17 2 It is not inadvertently peeled off from the laying sheet 1 and does not shift in position.

Next, as shown in Fig. 21 and Fig. 22, the root pot pressing sheet 7 is placed on the upper surface of the root pot 17. More specifically, the portion of the root-pellet pressing sheet 7 that is cut in 9 is used as a starting point, the tree 16 is inserted into the tree insertion hole 8 that communicates with the cutting portion 9, and the root basin pressing sheet 7 is placed thereon. The top of the root basin 17. At this time, since the cut-in 9 is formed from the tree insertion hole 8 so as to be formed toward the corner portion of one of the four corner portions, when the tree 16 is inserted into the tree insertion hole 8 of the base pot pressing sheet 7, the cut-in 9 is cut. It is well cracked, whereby the work of inserting the tree 16 into the tree insertion hole 8 can be easily performed.

Next, as shown in Figs. 23 and 24, the above-described base pot pressing sheet 7 and the locking tool 11 straddle the four binding bands 18. More specifically, as shown in the figure, one end portion of the binding tape 18 is locked to the locking body 12 of the locking tool 11, and in this state, the other end portion of the binding tape 18 is sequentially inserted into the base pot pressing sheet. The insertion hole 10 of the material 7 is returned to the other end side of the binding tape 18 on the side of the locking tool 11 , and the other end portion of the binding tape 18 is also locked to the locking body 12 of the locking tool 11 .

At this time, among the four straps 18, the three straps 18 are inserted into the insertion holes 10 of the three corner portions as shown in Fig. 25, and are returned to the side of the card holder 11, and one strap 18 is as shown in Fig. 25. The two insertion holes 10 which are cut into one corner portion formed by the cutting 9 are inserted and returned to the side of the locking tool 11 to be locked to the locking tool 11 respectively. In this manner, the four straps 18 are inserted into the insertion holes 10 that are inserted through the four corner portions of the root basin pressing sheet 7, and the both ends of the strap 18 are locked to be attached to the base. The locking members 11 of the four corners of the seat 2.

In this case, both end portions of the binding tape 18 are locked to one end portion of the locking body 12 of the locking tool 11, because the fixing body 13 that is locked to the other end side of the locking body 12 is nailed to The susceptor 2 generates a tension on the strap 18 by the tilting force or the like acting on the tree 16, and the strap 18 is not inadvertently detached, and the tension is appropriately generated across the latch body 12 and the base pot pressing sheet. The binding band 18 of the material forms the root basin 17 and is fixed. Further, since the binding tape 18 has a function of backstop as described above, the sheet for pressing across the locking body 12 and the root basin is not inadvertently loosened.

Thereafter, as shown in Fig. 26, by accommodating the soil 19 in the planting hole 15, the root basin 17 is buried in the soil 19, and the support processing of the trees is completed.

As described above, the support tool for trees of the present embodiment comprises a sheet for laying a coconut fiber, a sheet for pressing the base of the base made of polypropylene fibers 7, a wooden base 2, and a polyamide. The binding strap 18 is formed as a main component for holding the root basin, and for other auxiliary constituent elements, an iron base fixture 3 for fixing the base 2 and an iron lock for locking the strap 18 are used. In the construction of the construction tool, the supporting construction tool is formed in a simple structure, and a supporting construction tool capable of providing support processing suitable for a relatively small tree such as a street tree height of 3 m or less is achieved.

Moreover, the tying tape 18 is straddle the susceptor 2 and the base pot pressing sheet 7 on the laying sheet 1, and the susceptor 2 is fixed by the pedestal fixture 3, so that it is used as a street tree. The support of the tree supports the two-legged struts made of the conventional round used, and the support of the root pot of the present invention is relatively good.

Further, the sheet 1 for laying is covered with soil, and the weight of the soil acts on the sheet 1 for laying, and also acts on the straddle of the susceptor 2 and the tying belt 18 which are attached to the sheet for laying 1 The whole of the base pot pressing sheet 7 formed on the susceptor 2, therefore, the base pot 17 can be suitably supported in the underground portion, so that the method of supporting the trees on the ground portion is better than the method of using the above-described two-legged strut, the present invention The root pot support strength is better.

Further, since the base 2 is connected to the four wooden corner posts 2a, 2b, 2c, and 2d, the whole is formed into a substantially square frame shape, and when the root pot 17 is placed on the frame-shaped base 2 having a substantially square shape in this plane, The jamming occurs at the bottom of the root basin 17, and is inadvertently prevented by the inadvertent movement of the root basin 17.

Further, the natural fiber and the wood product constitute the so-called sheet for laying 1 and the main constituent elements of the susceptor 2 for holding the root pot. Therefore, when the supporting construction tool is buried in the soil for a certain number of years, these constituent elements are break down. Further, the base pot pressing sheet 7 made of synthetic fibers and the synthetic resin binder belt 18 are not decomposable materials in the soil, but may deteriorate to some extent after a certain number of years. Further, the metal base fixture 3 and the locking tool 11 which are hard to be disassembled are small in terms of component components, and therefore, even if they remain in the ground, the natural environment is less damaged. In short, in the present embodiment, it is possible to prevent the destruction of the natural environment without using a large-sized metal constituent element.

Further, in the fixing means for fixing the sheet 7 for pressing the root pot, it is not necessary to use a mechanical tool such as a winch, which is conventionally used for supporting construction of trees of Takagi, and can be used like a strap 18 The very simple components make construction easier and the cost is reduced.

Moreover, any constituent elements are also inexpensive, and the cost of supporting the entire construction tool is also cheap.

Further, in the above-described embodiment, as described above, the root pot 17 is placed in the planting hole 15 formed in the ground in advance, and the root pot 17 is supported by the underground portion, that is, the underground pillar is used, but the present invention is described. It is not limited to the case where it is applied to underground pillars.

Moreover, the shape and material of the sheet for laying 1, the susceptor 2, the susceptor fixture 3, the base pot pressing sheet 7, and the binding belt 18 are not limited to the above-described embodiments, and are within the intended scope of the present invention. Feel free to change.

The above description is only for the embodiments of the present invention, and any modifications and variations made by those skilled in the art using the present invention are the scope of the invention claimed, and are not limited to the embodiments disclosed.
