Description

[0001]
[Industrial applications]
The present invention relates to a tree curing structure and a tree curing method for supporting and erecting a tree such as a street tree.
[0002]
[Prior art]
There have conventionally been various structures for supporting and erecting a tree. The structure is shown below.
[0003]
The tree curing structure shown in FIG. 5 is such that a belt 53 is wound around a trunk 52 of a tree 51, one end of a wire 54 is connected to the belt 53, and the other end of the wire 54 is fixed to an anchor 56 fixed to the ground 55. It is configured to be connected to support the tree 51. The wires 54 are provided so as to extend radially in at least three directions at an equal angle around the tree 51.
[0004]
The tree curing structure shown in FIG. 6 is such that a cast iron plate 58 or the like is placed above the root soil 57 of the tree 51, and the tread pressure applied to the root pot is dispersed by the size of the plate surface. The cast iron plate 58 is divided into a plurality of parts, and is fixed to each other by a connection plate 59 and bolts 60.
[0005]
However, in the tree curing structure shown in FIG. 5 described above, since the wire 54 is provided so as to extend around the tree 51, there are problems that the wire 54 hinders walking and the appearance is not good. In addition, the tree 51 may rotate and fall due to a continuous wind having a different direction such as a typhoon, so that the support structure is not always perfect. Further, there is a problem that the belt 53 cuts into the trunk 52 as the tree 51 grows.
[0006]
On the other hand, in the tree curing structure shown in FIG. 6, when the cast iron plate 58 is formed to be large near the trunk 52 of the tree 51, the cast iron plate 58 bites into the trunk 52 as the tree 51 grows.
[0007]
In order to solve the problems of the wire support in FIG. 5 and the tree circle in FIG. 6, a tree curing structure as shown in FIG. 7 has been devised. In this tree curing structure, a root pot 62 is formed by covering a root soil portion of a tree 51 with a bag member 61 made of a plate material such as bamboo or hemp and a rope (not shown). An endless belt 63 is provided around the trunk 52 of the tree 51. An anchor 64 is fixed to the ground below the root bowl 62, and a tension belt 65 is stretched between the anchor 64 and the belt 63.
[0008]
The tension belt 65 is provided with a winch device 67, and a plurality of the winches are arranged so as to radially pull the belt 63. The tension belt 65 supports the tree 51 by urging the plurality of positions of the shoulder portion 68 at the peripheral edge of the upper surface of the root pot 62 downward. In the figure, reference numeral 69 denotes a protection pad for preventing the root pot 62 from collapsing.
[0009]
[Problems to be solved by the invention]
However, in the above-described tree curing structure (package-type underground strut) of FIG. 7, the shoulder portion 68 of the root basin 62 is urged downward by the tension belt 65 to support the tree 51, so that the tree 51 is supported. It was necessary to compact the soil. In particular, in the case of a large tree, it is necessary to strongly solidify the root soil, and as the root grows, the root bites into each member in the root pot 62, causing damage to the root, and harmful bacteria from the wound. Invasion caused problems such as root rot.
[0010]
Therefore, the present invention has been devised in order to solve the above-mentioned problems, and an object of the present invention is to prevent underground injury such as root rot and the like without damaging the rhizome even in a large tree.

[0026]
The fixed anchor 7 has a resistance plate (not shown) at the underground end, and the resistance plate expands in the ground at the time of driving, thereby obtaining a resistance against pulling.
[0027]
An angle member (see FIG. 4) for fixing the fixing plate 6 is provided along the longitudinal direction on the inner edge of the fixing frame 4. The angle member 14 has an L-shaped cross section, and is arranged such that one side thereof extends inward from the lower end of the fixed frame 4. The angle member 14 is divided at a connecting portion between the corner member 11 and the connecting member 12, and is attached to the corner member 11 and the connecting member 12 by welding.
[0028]
Bolts 15 extending upward are attached to the upper surfaces of both ends of each angle member 14. When the fixing plate 6 is attached, the fixing plate 6 is placed on the upper portion of the angle member 14, and a plate 16 having a hole through which the bolt 15 penetrates is placed on the fixing plate 6. Then, by screwing a nut 17 to the tip of a bolt 15 penetrating the plate 16, the fixing plate 6 is sandwiched between the angle member 14 and the plate 16, and the fixing plate 6 is fixed to the fixing frame 4. I have.
[0029]
The fixed plate 6 is formed of a rectangular grating, and is provided with four fixed plates 6. Specifically, the fixed plate 6 has a length obtained by adding the long side length and the short side length thereof to a length equal to one side of the fixed frame 4, and one side of the fixed frame 4 is provided with one fixed plate The long side of the fixing plate 6 and the short side of the other fixing plate 6 are arranged to be in contact with each other. That is, the four fixed plates 6 are arranged such that the short sides of the one fixed plate 6 adjacent to each other abut on the long sides of the other fixed plate 6. The outer shape of 6 is a square having a length equal to the sum of the long side length and the short side length of the fixed plate 6 (the length of one side of the fixed frame 4). In addition, a square opening 21 having a side length equal to the length obtained by subtracting the short side length from the long side length of the fixing plate 6 is formed inside the short side length of the fixed plate 6 from the outer periphery. . The tree 1 is located in the opening 21.
[0030]
A plate (not shown) to which an upwardly extending bolt (not shown) is fixed is provided below the four corners of the opening 21, and a plate 22 having a hole through which the bolt penetrates is placed on the plate, and a nut is mounted.

[0031]
A pipe 24 that opens to the ground is provided below the root mortar 3. The pipe 24 has flexibility and is provided such that one end is opened at a corner of the fixed frame 4 and the other end is opened at a diagonal corner of the fixed frame 4. A plurality of holes 25 are formed in the pipe 24 over the entire length thereof, and have a role of ensuring liquid permeability of the side part and the lower part of the root mortar 3 and supplying liquid fertilizer from an opening part of the end part. ing.
[0032]
The pipe 24 is made of a material (for example, paper or resin-based material) that is decomposed and returned to the soil when the root of the tree 1 grows and jumps out of the bag member 9 (two to three years after relocation). ). By this means, it is possible to secure the air permeability and supply the fertilizer under the ground until the tree 1 can grow sufficiently by the normal air permeability of the soil and the supply of fertilizer from above, thereby promoting the growth. Can be achieved. On the other hand, after the tree 1 has grown, the pipe 24 returns to the soil, so that the growth of the root is not hindered.
[0033]
Next, a description will be given of a tree curing method, which is an operation process for forming the tree curing structure having the above-described configuration, and an operation thereof.
[0034]
First, as shown in FIG. 2, a hole 26 slightly larger than the root pot 3 is excavated at a position where a tree is to be transplanted. Then, in the hole 26, two pipes 24 each having a plurality of holes 25 formed over the entire length are arranged in a cross shape so that both ends extend to the ground.
[0035]
Next, as shown in FIG. 3, the tree 1 integrated with the root pot 3 is moved into the hole 26. At this time, each end of the pipe 24 is formed longer so as to extend above the outer peripheral portion of the upper surface of the root mortar 3.
[0036]
Thereafter, as shown in FIG. 4, the fixed frame 4 is placed on the root mortar 3 such that its four corners protrude from the upper surface of the substantially circular root mortar 3. The fixed frame 4 can be set to an optimal size by setting the length of the connecting member 12 according to the size of the root mortar 3. The fixed frame 4 is divided at the time of installation, and is integrally formed by inserting a fitting portion (not shown) of the corner member 11 into the connection member 12 and fitting so as to surround the tree 1. I do.
[0037]
Simultaneously with the formation of the fixed frame 4, each pipe 24 is bent to the outer peripheral portion of the root mortar 3, and each end thereof is positioned inside the corner portion of the fixed frame 4.
[0038]
After that, the four fixing plates 6 are arranged in the fixing frame 4 as shown in FIG. 1, the plate 16 is placed on the angle member 14, and the nut 17 is screwed to the bolt 15, so that the angle member It is fixed to the fixed frame 4 with the fixing plate 6 interposed between the plate 14 and the plate 16. A plate (not shown) to which upwardly extending bolts are fixed is provided below the four corners of the opening 21 formed by the fixing plate 6, and the plate 22 is mounted on the plate, and the nut 23 is screwed to the bolt. As a result, the fixing plate 6 is sandwiched and fixed between the plate (not shown) and the plate 22.
[0039]
Next, the fixed anchors 7 are driven into the lower ground in the vicinity of the four corners of the fixed frame 4 and fixed, and one ends of the wires 18 are respectively hooked to the fixed anchors 7 and the other ends of the wires 18 are connected to the fixed frame 4. Respectively.
[0040]
Then, the end of the pipe 24 is cut in accordance with the upper end surface of the fixing plate 6. After that, artificial soil (granular) or soil is laid on the fixed plate 6, and turf and grass are planted. Note that the artificial soil is laid so as to avoid the opening of the pipe 24.
[0041]
As described above, by fixing the fixed frame 4 to the ground via the fixed anchor 7 and the wire 18, the fixed frame 4 and the fixed plate 6 urge the root pot 3 downward. As described above, since the root frame 3 is fixed by the entirety of the fixing frame 4 and the fixing plate 6, the root frame 3 can be pressed over a wide area. Accordingly, it is possible to reduce the treading pressure applied to the root mortar 3 and to reduce the load per unit area. Therefore, even if the tree 1 is a large tree, it is not necessary to compact the root mortar 3 as in the related art. The drainage in the pot 3 is improved, and even if the roots grow, they do not bite into the components, and do not damage the tree 1 unlike the package-type underground strut of FIG. 7, so that harmful bacteria can enter. Absent. Therefore, underground damage such as root rot can be prevented.
[0042]
Furthermore, since the pipe 24 provided with the hole 25 is provided from the side part of the root mortar 3 to the lower part so as to open to the ground, the lower part of the root mortar 3 has good air permeability and drainage is further improved. In addition, if water or fertilizer is supplied through the pipe 24, water or fertilizer can be supplied also from the lower part of the root, so that well-balanced supply of water or fertilizer can be performed. In this manner, water, fertilizer, and oxygen can be supplied from the lower part of the root mortar 3, so that the roots do not grow to the ground side but grow soundly deeper into the basement, and the stability of the tree 1 increases. In addition, the state of the underground part can be continuously checked through the pipe 24, and appropriate treatment can be performed in a timely manner.
[0043]
Further, since the fixing plate 6 is fixed to the fixing frame 4 via the angle members 14, the bolts 15, the plates 16, 22 and the nuts 17, 23, the fixing plate 6 can be easily replaced.
[0044]
Thus, the fixing plate 6 can be replaced with a smaller one in accordance with the growth of the tree 1, and the opening 21 can be made larger. Specifically, the fixing plate 6 is replaced with a fixing member whose long side is longer by a predetermined length and whose shorter side is shorter by a predetermined length. As a result, the opening 21 becomes large, so that even if the trunk 5 of the tree 1 becomes thick, the fixing plate 6 does not cut into the trunk 5.
[0045]
The replacement of the fixing plate 6 only needs to satisfy a condition that a length obtained by adding the long side length and the short side length is equal to one side of the fixed frame 4.
[0046]
In addition, since the fixing plate 6 is made of grating, the flow of water and the air permeability are good, and the effect of preventing root rot is improved. When the plant is planted, the growth of the turf and grass roots becomes good.
[0047]
Since the fixed frame 4 and the fixed plate 6 are hidden by planting grass, grass, and the like, the appearance is very good.
[0048]
【The invention's effect】
In short, according to the present invention, even if it is a large tree, the rhizome is not damaged, and the constituent members do not bite into the tree, so that an excellent effect of preventing underground damage such as root rot can be exhibited.
[0049]
Further, the appearance can be improved.
