Description

  The present invention is a method for supporting and supporting trees, and more specifically, artificially planted in various places in urban areas such as parks, sidewalks, exhibition halls, parking lots, plazas, plazas, public open spaces, etc. It is related with the support construction method of the tree for constructing while supporting the tree to be supported, and the support construction tool.

  In recent years, the demand for urban greening has increased, and in response to this, artificially planted in various places in urban areas, such as parks, sidewalks, exhibition halls, parking lots, plazas, plazas, public open spaces, etc. Construction methods for constructing trees while supporting them are being implemented. And in such a support construction method, it is necessary to fix the root pot of a tree in an underground part, and various methods and tools are conventionally employ | adopted as such a support construction method and a support construction tool.

  For example, a string-like body such as a wire is hung around the root pot, the string-like body is locked to a driving member such as an anchor, and the root pot is fixed by driving the driving member into the ground. In place of the anchor, a root pot is mounted on the mounting material, and a method of fixing the root pot by hanging a string-like body around the mounting material, or driving a pile-shaped member along the side surface of the root pot Although the method etc. are used, many of the support construction tools used for these methods are metal.

  However, since these support construction tools are installed around the root pot for the purpose of fixing the root pot, they are generally buried in the soil and left as they are. However, it is originally not preferable from the viewpoint of destruction of the natural environment that these metal support construction tools are left as they are embedded in the soil.

  Therefore, in view of such a point, for example, a method of driving a wooden pile along the side surface of the root pot is also performed, and as such a method, for example, a patent application such as the following Patent Document 1 is made. ing.

  That is, the method described in Patent Document 1 is a method in which a wooden support pile is driven along the peripheral surface of the root pot and a wooden root rod member is attached to the support pile in a lateral direction.

  However, in the method described in Patent Literature 1, two root members are obtained by inserting a pile into one of the root anchors having two rings and inserting a root member into the other ring. Since it is attached so as to straddle the other pile, there has been a problem that the work itself in which the pile and the root member are inserted into such a ring is complicated.

And fastening means for fastening the outer wrapping material.

  It is also possible to drive a plurality of piles into the ground after the outer wrapping material is tightened by the tightening means.

  For example, a winch or the like is used as the fastening means. By attaching the winch to the outer wrapping material, the tightening force can be suitably applied.

  In the present invention, as described above, a plurality of piles are driven into the ground along the root pot of the tree, a hook is attached to the upper part of the pile, and the outer hook is hung on the upper surface of the root pot. It can be constructed by hooking the turning material and hooking the inner hanging material at a position away from the outer hanging material latch and tightening the outer hanging material by the tightening means, Since it can be constructed using only a plurality of such tightening means such as piles, latches, two types of wrapping materials, and winches, such as the root member of the conventional technique is used. There is an effect that the work for supporting and supporting trees can be easily performed without complication.

  In addition, since the support construction tool is composed of only multiple stakes, latches, two types of wrapping materials, and winches, etc., the cost of the members used for support construction is also reduced compared to conventional tools. There is an effect that can be done.

  And the above-mentioned inner hanging material functions suitably so as to support the trunk portion of the tree as a trunk winding when a tree such as a thickened trunk grows after a certain number of years has passed since construction, and further the outer hanging material. Is hung around the upper surface of the root pot and functions suitably for fixing the root pot. Further, the root pot is fixed by a plurality of piles in which the outer hanging material is hooked through the hooks. Therefore, the whole root pot including the tree can be favorably supported as a tree support construction tool while having the simple configuration as described above.

It is wound and fixed so as to have a substantially S-shaped cross section.

  Next, a method for performing tree support construction using the tree support construction tool having the above-described configuration will be described. First, as shown in FIG. 12, a root pot 27 of a tree 26 is accommodated in a previously formed planting hole 25, and the root pot 27 is placed on the bottom wall surface 28 thereof.

  Next, the pile 1 is driven into the bottom wall surface 28 of the planting hole 25 along the side surface of the root pot 27. Prior to that, a hook 2 is attached to the pile 1. That is, as shown in FIGS. 13 to 15, the attachment piece 8 of the latch 2 is bent along the outer peripheral surface of the pile 1 having a circular cross section and is brought into contact with the outer peripheral surface of the pile 1. In this case, the attachment piece 8 of the latching tool 2 is provided with five elongated holes 11 on both the left and right sides as described above, so that the attachment piece 8 is made of metal. Nevertheless, the mounting piece 8 can be easily curved along the outer peripheral surface of the pile 1 having a circular cross section.

  Then, as shown in FIGS. 13 to 15, the nail 29 is driven into the pile 1 while being inserted into the holes 10 and 12 that are in communication with the hook piece 9 and the attachment piece 8. In this way, the latch 2 is attached to the pile 1. In addition, the latching tool 2 is attached so that it may be located in the lower side rather than the upper end 1b of the pile 1 as shown in FIG.13 and FIG.14.

  After attaching the latch 2 in advance to the pile 1 as described above, the pile 1 is driven into the bottom wall surface 28 along the side surface of the root pot 27 as shown in FIGS. In this case, the pile 1 is driven so as to be inclined slightly inward as shown in FIG. In the present embodiment, as shown in FIG. 17, a total of three piles 1 are driven along the side surface of the root pot 27 at substantially equal intervals. In addition, the height of the pile 1 after driving is set to a position where the upper end of the pile 1 is slightly higher than the upper surface of the root pot 27 as shown in FIG. 16, and as shown in FIG. The direction in which the pile 1 should be driven is set so that the hook piece 9 of the tool 2 faces outward. As shown in FIG. 16, it is desirable to preliminarily deposit the spare customer land 30 on the bottom wall surface 28.

  Next, as shown in FIGS. 18 and 19, the outer hanging belt 3 is hung on the upper surface of the root pot 27, and the outer hanging belt 3 is hooked on the hook 2. More specifically, as shown in FIGS. 13 to 15, the outer hanging belt 3 is hooked at the position of the hook piece 9 of the hooking tool 2, particularly the tip-side tip hooking portion 9 d. In this case, since the three piles 1 to which the latching tool 2 is attached are driven at substantially equal intervals along the periphery of the root pot, the outer hanging belt 3 is as shown in FIG. Then, they are hung so as to form a substantially equilateral triangle in plan view.

  Further, in this case, the hook piece 9 of the hook 2 includes a rising portion 9b that is formed on the upper portion of the attachment portion 9a that is an attachment portion to the attachment piece 8, and an upper bent portion 9c of the rising portion 9b. Since the whole is formed in a hook shape, the belt 3 is inadvertently detached from the hook piece 9. There is no such thing.

  Moreover, both sides of the hook piece 9 are tapered so that the rising portion 9b is gradually widened upward, and the tip hooking portion 9d is gradually narrowed downward from the upper bent portion 9c. Is formed in a tapered shape, and as a result, the vicinity of the upper bent portion 9c is configured to be the widest, so that the outer hanging belt 3 is suitably hooked on the hook piece 9. It is.

  In a state where the outer hanging belt 3 is hung on the upper surface of the root pot in this way, both ends of the outer hanging belt 3 are attached to the winch 5 and the mounting bracket 6 as shown in FIG. It has become. More specifically, as shown in FIG. 20, one end 3 a side of the outer hanging belt 3 is inserted into the long hole 18 of the mounting bracket 6, and the other end 3 b side of the outer hanging belt 3 is inserted into the long hole 17 of the winch 5. Thus, both end portions of the outer hanging belt 3 are attached to the winch 5 and the mounting bracket 6.

  In addition, in the state where the outer hanging belt 3 is hung on the upper surface of the root pot and is hooked on the hook 2 in this way, the tightening by the winch 5 is not yet performed. 3 is in a slightly loosened state as shown in FIG.

  Next, as shown in FIGS. 21 and 22, the inner hanging belt 4 is hung on the upper surface of the root pot at a position relatively close to the trunk of the tree 26, and is hooked on the outer hanging belt 3. Let In this case, the inner hanging belt 4 is hooked on three sides of the outer hanging belt 3 that is hung on the upper surface of the root pot so as to form a substantially equilateral triangle, and as a result, the inner hanging belt 4 itself. Is also formed on a top surface of the root pot so as to form a substantially equilateral triangle in a plan view and to be surrounded by the outside hanging belt 3.

In this case, both ends 4a and 4b of the inner hanging belt 4 are fixed by the fixing bracket 7 as shown in FIG.

  Then, the inner hanging belt 3 is hooked on the outer hanging belt 3 in this way, and each of them is hung on the upper surface of the root pot, and then the outer hanging belt 3 is fastened with the winch 5. As shown in FIG. 22, immediately after the inner hanging belt 4 is hooked on the outer hanging belt 3, the outer hanging belt 3 seems to be slightly narrowed by the inner hanging belt 4 as shown in FIG. In this state, by tightening the outer hanging belt 3 with the winch 5, the outer hanging belt 3 is stretched straight as shown in FIG. As the outer hanging belt 3 is stretched in this way, the root pot 27 is fixed, and the tension force of the outer hanging belt 3 acts on the plurality of piles 1 via the hooks 2. The effect | action which fixes the root basin 27 with the pressing force to the root basin 27 side by the some pile 1 will increase further.

  Next, as shown in the direction of the arrow in FIG. 24, the pile 1 is further driven into the ground from the driven state. In this case, the driving position of the pile 1 is set so that the upper end portion of the pile 1 is located slightly below the upper surface of the root pot.

  Thereafter, soil is put into the planting hole 25 to close the planting hole 25, thereby completing the tree support construction.

In the above embodiment, a total of three piles 1 are driven into the ground along the side surface of the root pot 27, but the number of piles 1 to be driven is not limited to the above embodiment. For example, four piles 1 It is also possible to type in. The point is that a plurality of piles 1 need only be driven along the side surface of the root pot 17.
Moreover, in the said embodiment, after attaching the latching tool 2 to the some pile 1 previously, the some pile 1 was driven in the ground along the root pot 27, but on the contrary, the some pile 1 It is also possible to attach the latching tool 2 to the pile 1 after being driven into the ground, before and after the procedure. However, from the viewpoint of workability, it is desirable to drive the pile 1 into the ground after attaching the latch 2 to the pile 1 in advance as in the above embodiment.
Furthermore, in the above embodiment, the outer hanging belt 3 is hung on the upper surface of the root pot 27 and then the inner hanging belt 3 is hung on the outer hanging belt 3. It is also possible to hang around the wrapping belt 3 and hang the outer wrapping belt 3 around which the inner wrapping belt 4 is wound around the upper surface of the root pot 27. However, from the viewpoint of workability, it is desirable that the outer hanging belt 3 is hung on the upper surface of the root pot 27 and then the inner hanging belt 3 is hung on the outer hanging belt 3.

Moreover, in the said embodiment, although the latching tool 2 comprised the above attachment piece 8 and the hook piece 9, the structure of the latching tool 2 is not limited to the said embodiment. . Further, the configurations of the winch 5 and the mounting bracket 6 are not limited to the above-described embodiment, and can be arbitrarily changed within the scope intended by the present invention.
Further, in the above embodiment, the outer hanging belt 3 and the inner hanging belt 4 formed in a flat plate shape are used as the outer hanging member and the inner hanging member, but the outer hanging member and the inner hanging member are used. The shape of the member is not limited to the flat shape of the embodiment, and for example, a member formed in a rope shape having a circular cross section may be used. Further, instead of the winch 5, other fastening means can be used as the fastening means.
Furthermore, in the above embodiment, since the pile 1 is driven in a state inclined slightly inward,
Although there is a possibility that a part of the pile 1 does not contact the root pot 27 and a part of the pile 1 is slightly separated from the root pot 27, it is not a condition for the substantially whole pile 1 to contact the root pot 27. . That is, in the present invention, “driving the pile 1 along the root pot 17 into the ground” means that the pile 1 is placed along the root pot 17 regardless of whether the pile 1 is brought into contact with the root pot. .

  In the present invention, as described above, from the viewpoint of destruction of the natural environment, the main purpose is to use the wooden pile 1, but the scope of the present invention is not limited to the wooden one but also when using a metal pile. include. In addition, the present invention is mainly applied to the construction of a so-called underground strut in which a root pot 17 is housed in a planting hole 15 formed in advance on a general ground and a tree is supported and constructed. In addition to general ground, the present invention can also be applied to support construction of trees on artificial ground. When used for such an artificial ground, it is not necessary to form the planting hole 15, and it is possible to support the tree by stacking artificial soil so that the root pot 17 is embedded.
