Description

  The present invention relates to a method for supporting and supporting trees, and a fixing tool for root pots used in the method for supporting and supporting, more specifically, while supporting trees artificially planted in parks, rooftop gardens, pavements, etc. TECHNICAL FIELD The present invention relates to a method for supporting a tree to be used and a fixing tool for a root pot used in the method for supporting and supporting the tree.

  Conventionally, there are techniques such as Patent Document 1, Patent Document 2, and Patent Document 3 described below as techniques for supporting and constructing this type of tree. Patent Document 1 relates to an invention of a planting method for planting trees, in which a resistance plate driven into the bottom of a planting hole is placed with a ring-shaped stationary plate, and a wire rope is hung around the resistance plate to support the tree A method is disclosed.

  Patent Document 2 relates to an invention of a tree support construction apparatus, in which a root pot of a tree is placed on a fixed base having a net-like steel plate fixed to an outer frame, and a floor covering is provided at the center of the bottom of the root pot of the tree. And connecting the fixed ends of the fixed wires to point-symmetrical positions on the orthogonal line of the flooring material, and branching wire portions extending from the fixed ends into two strips with free ends, the root portions of the trees Are arranged along the outer peripheral surface of the root basin so as to surround in a substantially square shape and circulate in opposite directions, respectively, and the free end of the branch wire portion is connected to the fixed base via a fastening bracket. The support construction apparatus of the tree connected and fixed to the outer frame is disclosed.

Further, Patent Document 3 relates to a method for supporting a tree and a device for supporting the tree. After a base frame is placed on the bottom surface of the planting hole, a root pot of a tree placed in the center of the top surface of the base frame is tied to the base frame. In the method of supporting a tree in which the planting hole is backfilled, a plurality of support legs each having a pressing plate fixed to the projecting end are provided on the outer periphery of the base frame so as to be movable in and out in the radial direction, thereby filling the planting hole. Prior to returning, a support method is disclosed in which each support leg is protruded so that the pressing plate is in contact with the vertical side surface of the planting hole, and each support leg is fixed to the base frame at this position of contact.

  However, the tree support construction techniques as described above are common in that they support the tree by hanging a string such as a wire rope or belt around the root pot. In the technique of supporting the tree by hanging around the root pot, a gap is inevitably generated between the root pot and the bottom of the planting hole. There was a problem that the balance of force was lost and the root pot might be distorted and collapsed.

  In addition, in the case of a method of supporting a tree by hanging a string-like body around a root pot, there is a possibility that force concentrates on one point of the shoulder of the root pot around which the string-like body is hung. There was a risk of collapse of the concentrated shoulder. In addition, in the techniques of Patent Documents 1 to 3, there is also a technique of pressing the shoulder of the root pot with a rigid member other than the string-like body. It was an inevitable problem.

And when the shoulder part of the root pot collapsed in this way, it became a factor that the whole root pot collapsed.
In addition, once the root pot collapses and the tree is tilted in this way, the root is separated from the root pot even if the root pot and the tree are reestablished. There was a point.

  Furthermore, if the tree is fixed too much, the growth of the trunk becomes distorted and the amount of rooting is reduced. For example, if the trunk is fixed too firmly with a wooden support or the like, there is a property that the portion of the trunk below the fixed portion becomes thin.

  The present invention has been made in order to solve the above-described problems, and it is not necessary to use the above-described conventional wire rope, belt, or other string material. This eliminates problems such as a gap between the bottom of the planting hole and prevents the root pot from collapsing due to the movement of the root pot, and does not concentrate force on one point of the shoulder of the root pot. Another object of the present invention is to prevent the collapse of the shoulder of the root pot.

In order to solve such problems, the present invention was made as a method for supporting and supporting trees, and as a fixing tool for root pots used in the method for supporting and supporting trees. The described invention narrows down the upper part of the enveloping material 1 for encapsulating the root pot 10 of the tree, and places the mounting material 2 from the back side to the front side of the mounting material 2 for mounting the root pot 10. 2 is passed through the hole 5 drilled in the approximate center, and the enveloping material 1 is pulled up and attached to the periphery of the hole 5 on the back surface side of the placing material 2 at the bottom of the encapsulating material 1. By locking the locking member 4, the lower part of the enveloping material 1 is fixed to the mounting material 2, and the root pot 10 is connected to the enveloping material 1 from the opening 3 on the upper surface of the enveloping material 1. housed within, over said while fixing the lower portion of the dressing 1 before described置材2, the root ball 10 in the envelope material 1 from below By enclosing the wrapping material 1 along the periphery of the root pot 10 and tightening the edge of the opening 3 of the wrapping material 1 to fix the root pot 10. It is characterized in that it is constructed in support of trees.

Furthermore, the invention according to claim 2 relating to a tree root pot fixing tool has an opening 3 on the upper surface that can store a tree root pot 10, and when the tree root pot 10 is stored, the root pot 10 Is encased so as to be wrapped from the lower side toward the upper side, and the enveloping material 1 is made of a flexible material capable of tightening the edge of the opening 3 along the periphery of the root pot 10. When the formed a root ball 10 to a size that can be placed, and the comprises a置材2 mounting having means capable of fixing the lower portion of the packaging material 1, and the placing A hole 5 is formed in the approximate center of the material 2, and a locking member 4 that is locked to the peripheral edge of the hole 5 of the mounting material 2 is attached to the bottom of the enveloping material 1. The upper part of the packaging material 1 is squeezed and passed through the hole 5 of the placement material 2 from the back surface side to the front surface side of the placement material 2 described above. The lower part of the enveloping material 1 is fixed to the mounting material 2 by pulling up 1 and engaging the engaging member 4 of the enveloping material 1 with the periphery of the hole 5 on the back surface side of the placing material 2.

Therefore, the root pot can be reliably fixed by the enveloping material for encapsulating such a root pot and the placement material for placing the root pot.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  First, a root pot encapsulating material 1 and a root pot mounting material 2 constituting a root pot fixing tool are prepared.

    An enveloping material 1 for a root pot is composed entirely of a net made of synthetic resin, and has an opening 3 on the upper surface as shown in FIGS. 1 and 2, and the lower surface is closed by narrowing the net. The whole is formed in a substantially cylindrical shape with a bottom. A small ring-shaped locking member 4 made of metal is attached to the bottom of the enveloping material 1. As described later, it is possible to use a material other than the synthetic resin net as the enveloping material 1. Further, as the locking member 4, a member other than the ring shape can be used.

  The mounting material 2 for root pots is formed of a mat made of palm fibers, more specifically, a mat formed by knitting or weaving palm fibers in a finely knitted state, as shown in FIGS. As shown in FIG. 5, the entire surface is formed in a substantially square shape. A small hole 5 is formed in the approximate center of the mounting material 2. The diameter of the hole 5 is formed to be slightly smaller than the inner diameter of the locking member 4 attached to the bottom of the enveloping material 1.

  Next, the encapsulating material 1 and the placing material 2 are combined to form a root pot fixture 7 as shown in FIG.

  More specifically, the upper portion of the enveloping material 1 is narrowed down to pass the hole 5 of the placing material 2 from the back surface side to the front surface side of the placing material 2, and the encapsulating material 1 is pulled up. In this case, the diameter of the circular hole 5 drilled in the mounting material 2 is formed to be slightly smaller than the inner diameter of the locking member 4 attached to the bottom of the enveloping material 1, that is, Since the inner diameter of the locking member 4 of the enveloping material 1 is formed larger than the diameter of the hole 5 of the mounting material 2, the locking member 4 of the enveloping material 1 is the peripheral portion of the hole 5 of the mounting material 2. Accordingly, the removal of the placement material 2 from the hole 5 is preferably prohibited. In this way, the potting material 1 and the placement material 2 constitute the root pot fixing tool 7.

  Next, as shown in FIG. 6, the root pot fixing tool 7 is installed in the planting hole 9 formed in advance on the ground, and the root pot 10 is stored in the enveloping material 1 of the root pot fixing tool 7. . More specifically, the placement material 2 of the root pot fixing tool 7 is placed on the soil 11 spread on the bottom surface of the planting hole 9, and the root pot 10 is removed from the opening 3 of the enveloping material 1. The container 1 is housed and the enveloping material 1 is pulled upward along the side wall surface of the root pot 10.

  In this case, the enveloping material 1 is pulled up while being brought into contact with the side wall surface of the root pot 10 so that the enveloping material 1 is not loosened. 2 is locked to the peripheral edge of the hole 5 and the covering material 1 is prevented from coming out of the hole 5 of the mounting material 2, so that the covering material 1 is in contact with the side wall surface of the root pot 10, The root pot 10 can be encapsulated with the enveloping material 1 along the outer shape of the root pot 10.

  Next, as shown in FIGS. 7 and 8, the cord material 12 is inserted into the peripheral portion of the opening 3 of the enveloping material 1, and the cord material 12 is pulled to tighten the enveloping material 1. As a result, the opening 3 of the enveloping material 1 is not blocked, but the area of the opening 3 is reduced, and as a result, as shown in FIG. 1 will be covered.

  In this way, the locking member 4 of the enveloping material 1 is engaged with the peripheral edge of the hole 5 on the back surface side of the mounting material 2 to prevent the enveloping material 1 from coming out of the hole 5 of the mounting material 2. In this state, the base material 10 is covered with the enveloping material 1 by pulling the string material 12 to tighten the enveloping material 1, so that the entire bottom surface portion, side surface portion, and top surface portion of the root pot 10 are covered with the enveloping material. 1 is fixed so as to be wrapped from the lower side toward the upper side. In particular, since the hole 5 of the mounting material 2 is formed to have a diameter smaller than the diameter of the root pot 10, the effect of encapsulating the root pot 10 with the enveloping material 1 from the lower side to the upper side is preferable. Can be demonstrated.

  Therefore, there is no need to use a string material such as a wire rope or a belt as in the prior art, and there is no gap between the root pot and the bottom of the planting hole as in the case of using such a string material, The root pot can be prevented from collapsing due to the movement of the root pot, and the force does not concentrate on one point of the shoulder of the root pot, and the collapse of the root pot at the shoulder can also be prevented. . Moreover, because trees are not fixed too much, the growth of the trunk will not be poor, and rooting will not be reduced.

After fixing the root pot with the enveloping material 1 and the mounting material 2 as described above, as shown in FIG.
Is buried in the planting hole 9. This completes the tree support construction.

In the above-described embodiment, since the net-like material made of synthetic resin is used as the enveloping material 1, the lifting force when encapsulating the root pot 10 so as to wrap from the lower side to the upper side effectively acts to A preferable effect that the pot 10 can be fixed without being damaged and the air permeability can be maintained is obtained, but the material of the enveloping material 1 is not limited to a net-like material made of synthetic resin.

  In addition to synthetic resins, it is also possible to use nets made of natural materials such as hemp, cotton, natural fibers, synthetic fibers, biodegradable fibers, biodegradable resins, etc., and a network structure generally recognized as a net For example, those in which minute holes are perforated in woven fabric, nonwoven fabric, etc., in which rectangular spaces are opened by slit fabric, flat fibers such as flat yarns are vertically and horizontally It is also possible to use a woven fabric in which gaps are formed between the vertical and horizontal yarns. It is also possible to use an extremely fine metal net.

  However, it needs to be made of a flexible material that can be encapsulated along the root pot, and preferably has air permeability. From this point of view, the one having space and flexibility is mainly used.

  Moreover, in the said embodiment, although the ring-shaped thing was used as the latching member 4, the shape of the latching member 4 is not limited to this embodiment.

  Moreover, in the said embodiment, although the mounting material 2 was comprised by the mat-shaped thing which knit | knitted or woven the palm fiber, the material of the mounting material 2 is not limited to this embodiment. For example, hemp or cotton can be used. It is also possible to use paper. Furthermore, in addition to such natural materials, it is also possible to use non-woven fabrics or synthetic fibers, synthetic resins, biodegradable fibers, biodegradable resins and the like. However, it is preferably made of a material that is likely to cause surface resistance in the mounted state, or formed in a shape that is likely to cause surface resistance.

  Furthermore, in the said embodiment, although the mounting material 2 was formed in planar substantially square shape, the shape of the mounting material 2 is not limited to this embodiment, For example, it forms in a substantially circular shape or a substantially triangular shape. It is possible to do this, and the shape is not limited.

  Furthermore, in the said embodiment, only the root pot 10 was accommodated in the enveloping material 1, but it is not restricted to this, For example, as shown in FIG. It is also possible to store the root pot 10 in a state where it is placed on the base. In this case, there is an advantage that the height of the root pot 10 to be installed can be adjusted according to the depth of the planting hole 9 by adjusting the amount of the soil 14. As the soil in this case, it is possible to use artificial soil as well as natural soil, and further, other than soil, for example, a granular material obtained by foaming clay minerals such as obsidian perlite and nacreous perlite, glass It is also possible to accommodate cullet (glass foam), crushed stone, tricarnet (synthetic resin network having a three-dimensional structure) and the like.

  By storing these items, effects such as improved drainage are produced.

  Furthermore, as shown in FIG. 11, it is possible to drive a pile 15 into the periphery of the mounting material 2. By driving such piles 15, it is possible to suitably prevent the placement material 2 from being unintentionally displaced when being installed in the planting hole 9.

Furthermore, in each said embodiment, the root pot fixing tool 7 which consists of the covering material 1 and the mounting material 2 is installed in the planting hole 9, and the root pot 10 is accommodated in the covering material 1, and the covering material After being encapsulated in 1, the planting hole 9 was closed with soil and the tree was supported and constructed by a so-called underground strut method. However, the present invention is not limited to this, and the present invention is not limited to this. It is also possible to apply.

When applied to such a roof garden, for example, as shown in FIG. 12, the root pot fixing tool 7 can be constituted by a single placement material 2 and a plurality of enveloping materials 1. . In this case, a plurality of holes 5 are formed in one mounting material 2, and the locking member 4 at the bottom of the enveloping material 1 as described in the above embodiment is used as a peripheral portion on the back side of the hole 5. The plurality of enveloping materials 1 are attached to the single placement material 2 by being locked to each other.

  In the example of FIG. 12, since it is applied to the roof garden, as shown in the figure, first, the basic soil 17 is laminated on the concrete portion 16 constituting the roof, and the root pot 10 is stored in each enveloping material 1 and encapsulated. A plurality of root pots 10 are placed on the upper portion of the basic soil 17 by being encapsulated with the material 1, and a plurality of root pots 10 are embedded in the embankment 18 by laminating the embankment 18 in that state, whereby a plurality of root pots 10 are embedded in the roof garden. Trees will be supported and constructed.

  Further, instead of using such a single mounting material 2, a plurality of mounting materials 2 may be combined, and the enveloping material 1 may be attached to each of them, and a tree may be arranged geometrically for support construction. It is possible, and when arranging trees geometrically in this way, the shape of the mounting material 2 and the arrangement mode of the enveloping material 1 on the mounting material 2 do not matter.
