Hereinafter, preferred embodiments of the planted tree support structure and method according to the present invention will be described with reference to the drawings.
The supporting structure of the planted tree of the first embodiment shown in FIG. 1 includes a recess 2 formed by a planting hole formed in the ground for placing the root pot 1 of the tree T, and a root pot 1 in the recess 2. A plurality of (four in the illustrated example) driven piles 3 are mounted along the peripheral surface of the slab, and the root member 4 which is attached to each of the support piles 3 and serves as an anchor in the recess 2 is attached sideways. It comprises a root anchor 5 and a fastening member 10 provided above the root anchor 5 by the support pile 3 and tightening the support piles 3 along the root pot 1.
[0007]
Here, the support pile 3 is a log whose tip has been cut, but it is inexpensive because it uses thinning, and it is not necessary to perform creosote preservative treatment that can be used with a white tree and is performed on a ground support. It is preferred to use reduced cedar logs.
The support pile 3 is driven along the peripheral surface of the root pot 1 in the recess 2.
When driving, it is preferable to drive the support pile 3 at an angle so that the support pile 3 is vertical after tightening.
[0008]
The support pile 3 may have a configuration in which the root anchor fitting 5 is mounted in advance at a midway position. However, in this embodiment, the root anchor attachment 5 is separated from the support pile 3. After the support pile 3 is driven, the support pile 3 is inserted and attached.
[0009]
That is, in the present embodiment, the root anchor fitting 5 is made of metal such as iron, and the first ring 5a that can be inserted into the support pile 3 and the root member 4 are fixed to the first ring 5a at right angles. It consists of a second ring 5b that can be inserted.
Therefore, in order to attach the root member 4 to the support pile 3, it is only necessary to insert the first ring 5 a into the support pile 3 and insert it to the bottom of the recess 2.
[0010]
Next, on the support pile 3, a fastening member 10 for fastening the support piles 3 to each other using a wire rope or the like above the mounting position of the root member 4 so that its upper end does not protrude above the ground. At the upper end of the recess 2 in the illustrated example, it is mounted at a position that substantially coincides with the ground line.
As the fastening member 10, a member having a known configuration can be used as appropriate, but in the case of the present embodiment, as an example, the first fastening tool 11 and the second fastening tool 12 are used.
[0011]
As shown in FIG. 4, the first fastener 11 has a bracket 11c pivotally supported on one end of a ring 11a and a bolt 11b for tying a wire rope W at the tip thereof, and at a position orthogonal to the bracket 11c. A winch 11f with a reverse rotation preventing claw 11e that pulls and winds the wire rope W through an arm 11d is provided.
Moreover, the 2nd fastener 12 consists of the ring 12a with the sheave 12b used as a fixed pulley.
[0012]
Therefore, as shown in FIG. 3, the ring 11 a of the first fastener 11 is inserted and attached to one support pile 3, and the second fastener is attached to the remaining support pile 3. Twelve rings 12a are inserted and attached.
Then, the wire rope W having one end tied to the bolt 11b of the first fastener 11 is passed through the sheave 12b of the second fastener 12, and the other end is taken up by the winch 11f of the first fastener 11. Then, the support piles 3 are pulled and tightened in the shrinking direction of the wire rope W wound in an annular shape.
[0013]
After the tightening and fixing, the support piles protruding to the upper ends of the rings 11a and 12a of the first and second fasteners 11 and 12 are cut off.
A cut piece 3 ′ of the support pile 3 is used as a root member 5 serving as an anchor.
That is, the root anchor member 5 made of a log is inserted into the second ring 5b of the root anchor fixture 5 to become an anchor (see FIG. 1B).
Next, by refilling the concave portion 2, the root pot 1, the root anchor member 4, and the support pile 3 are embedded, and the support pile 3 functions as an underground strut.
[0014]
In the said Example, although the upper part of the support pile 3 was cut | disconnected and utilized as the root member 4, you may prepare separately the wooden root member 4, such as a log, beforehand.
Moreover, although the support pile 3 showed the example embed | buried in the ground to an upper end, the upper part may be exposed to the ground or may protrude.
[0015]
The support structure of the planted tree T according to the second embodiment shown in FIG. 2 is a fastening member for final fastening that is attached as a fastening member in the middle of the support pile 3 and above the root anchor fitting 5. 10A and a temporary fastening member 10B attached to a position above the final fastening member 10A are used in two stages, and the other configurations are the same as those in the first embodiment.
[0016]
Here, the final fastening member 10 </ b> A has a configuration using the first fastening tool 11 and the second fastening tool 12 in the same manner as the fastening member 10 of the first embodiment.
The temporary fastening member 10B may be exactly the same as the final fastening member 10A. In this embodiment, the first fastening tool 11 and the ring 11a of the second fastening tool 12, 12a has a cap shape that is detachably fitted to the upper end of the support pile 3, and the other configurations are the same, and thus the description thereof is omitted.
[0017]
With the above-described configuration, when tightening the tightening member, the final tightening tightening member 10A and the temporary tightening tightening member 10B are used, and the wire ropes W are alternately tightened to fix the support pile 3 to the root. Fix along the pot 2.
In this embodiment, since the final fastening fastening member 10A and the temporary fastening fastening member 10B are used as the fastening members, all the support piles 3 can be tightened along the root pot 1 more firmly.
[0018]
Then, after this tightening, the upper portion of the support pile 3 protruding upward from the final tightening tightening member 10 </ b> A is cut, and the cut piece 3 ′ is used as the root member 4.
At the time of cutting the cut piece 3 ′, the temporary fastening member 10B may be unfastened and removed from the support pile 3 in advance, or may be removed after cutting.
[0019]
Then, as described above, the root anchor member 4 is inserted into the root anchor fixture 5 to be hooked or fixed to form an anchor, the recess 2 is backfilled, and the remaining support pile 3 is replaced with the root pot 1 or the root anchor. By embedding with the member 4, it can function as an underground strut.
Although the support pile 3 showed the example embed | buried under the ground to an upper end, the upper part may be exposed to the ground or may protrude also in this case.
[0020]
The support structure of the planted tree of the third embodiment shown in FIGS. 5 and 6 shows a different embodiment of the tightening member (the tightening member 10A for final tightening in the illustrated example).
Other configurations are the same as those of the second embodiment.
In this case, the slide link type third fastener 13 and the fourth fastener 14 are used as the fastening members.
[0021]
The third fastening tool 13 and the fourth fastening tool 14 are both used between two adjacent support piles 3 and 3 for use.
That is, as shown in FIG. 8, the third fastener 13 is separated from the right and left by a pair of rings 13a inserted into the support pile 3 and a bracket 13h fixed to the pair of rings 13a. It has a link 13i that can be adjusted in length and spanned between 13a.
[0022]
The link 13i has a double-pipe structure, and can be expanded and contracted. A plurality of length adjustment holes are formed in the inner pipe, and one of the selected length adjustment holes is connected to the outer pipe. A known length adjustment structure is used that can be adjusted to a desired length by bolting in alignment with the reference hole.
[0023]
In addition, a bracket 13c that pivotally supports a bolt 13b for connecting the wire rope W to the tip is fixed to one ring 13a at a position orthogonal to the bracket 13h. An arm 13d is fixed to the other ring 13a at a position orthogonal to the bracket 13h, and a winch 13f with a reverse rotation preventing claw 13e is pivotally attached to the arm 13d.
[0024]
Next, as shown in FIG. 9, the fourth fastener 14 is bridged between the ring 14a via a pair of rings 14a inserted into the support pile 3 and a bracket 14h fixed to the pair of rings 14a. The third fastening tool 13 is the same as the third fastening tool 13 in that it has a length-adjustable link 14i.
A pair of rings 14a is fixed with a sheave 14j serving as a fixed pulley at a position orthogonal to the bracket 14h.
[0025]
In the third embodiment, as shown in FIG. 6, a third fastener 13 in which the two adjacent support piles 3 driven into one set are set as one set and the length of the link 13 i is adjusted to one set. The ring 13a is inserted into the support pile 3 and attached, and the ring 14a of the fourth fastener 14 is inserted and attached to the other opposing pair.
[0026]
Then, the wire rope W tied to one end of the bolt 13b of the bracket 13c of the third fastener 13 passes through the sheaves 14j and 14j at both ends of the fourth fastener 14 and then returns to the winch 13f of the third fastener 13. The support pile 3 can be tightened by tying it with the winch 13f and winding it.
[0027]
In this case as well, the support pile 3 is firmly tightened with the fastening member 10A for final fastening and the fastening member for temporary fastening (not shown), and the upper part is cut from each ring of the fastening member 10A for final fastening, This cut piece 3 'is inserted into the root anchor fixture 5 as a root anchor member 5, and the recess 2 is backfilled and used as an anchor in the same manner as in the above embodiment.
[0028]
Next, the support structure of the planted tree T of the fourth embodiment shown in FIGS. 7 and 10 shows a different embodiment of the fastening member 10A for final fastening when eight support piles 3 are used.
Other configurations are the same as those of the second embodiment.
In this case, the slide link type fifth fastener 15 is used as the fastening member.
[0029]
The fifth fastener 15 is used between two adjacent support piles for use. As shown in FIG. 11, the fifth fastener 15 is a pair of rings that are inserted into the support pile 3 while being separated from each other left and right. 15a and a link 15i having a length adjustable between the rings 15a via a bracket 15h fixed to the pair of rings 15a.
The link 15 i has the same length adjustment structure as the links 13 i and 14 i of the third and fourth fasteners 13 and 14.
[0030]
An arm 15d is fixed to one ring 15a at a position orthogonal to the bracket 15h, and a winch 15f with a reverse rotation preventing claw 15e is pivotally attached to the arm 15d.
Further, a sheave 15j serving as a fixed pulley is fixed to the other ring 15a at a position orthogonal to the bracket 15h.
[0031]
In the fourth embodiment, as shown in FIG. 10, four sets of fifth fasteners 15 in which the lengths of the links 15 i are adjusted with the adjacent two of the eight driven support piles 3 as one set are The support piles 3 are inserted and attached to the rings 15a.
And the winch 15f of each 5th fastening tool 15 is fastened by spanning the wire rope W between the sheave 15j which the other 5th fastening tool 15 opposes.
[0032]
In the support structure of the planted tree T of the fourth embodiment, the second ring 5b of the pair of root anchors 5 and 5 between the adjacent support piles 3 that are not connected by the same fifth fastener 15; 5b are arranged on a coaxial line, and one long root member 4 is inserted between the two and spanned.
In this case, although the support pile 3 is eight, the root anchor member 4 may be four.
[0033]
When this root anchor member 4 cuts the upper part of the support pile 3, it is necessary to make the length which the support pile 3 cuts longer than the case of the said Example (it is longer than the space | interval of the adjacent support piles 3 and 3). However, it is only necessary to obtain the root member 4 from at least four support piles 3, and it is not necessary to obtain the root member 4 from other support piles 3.
Alternatively, instead of using the cut piece 3 ′ of the support pile 3 as the root member 4, a log cut into a predetermined length may be prepared in advance as the root member 4.
[0034]
Next, the support structure of the planted tree T of the fifth embodiment shown in FIGS. 12 and 13 shows still another embodiment of the fastening member 10 </ b> A for final fastening using the eight support piles 3.
In this case, the third fastening tool 13 shown in FIG. 8 and the fourth fastening tool 14 shown in FIG. 9 are used in combination as the fastening member, as in the third embodiment.
That is, two sets of the third fastening tool 13 and the fourth fastening tool 14 are used between the adjacent support piles 3 and 3 so as to face each other.
[0035]
Therefore, the tightening member in the third embodiment is used in combination in a cross shape.
Further, the root anchor member 5 made of the cut piece 3 ′ of the support pile 3 is inserted into each root anchor fixture 5.
In addition, in the example of illustration, as another example of the attachment position of the root anchor fixture 5, the height difference is given a little alternately, but all may be made into the same height position.
Thus, the attachment position of the root anchor 5 is not uniform and may be changed as appropriate.
Since other configurations are the same as those in the above embodiment, the description thereof is omitted.
[0036]
Next, the support structure of the planted tree T of the sixth embodiment shown in FIGS. 14 and 15 shows another embodiment of a fastening member 10A for final fastening using 12 support piles 3.
In this case, only the third fastening tool 13 of FIG. 8 is used for the fastening member 10A.
That is, six sets of the third fasteners 13 are used between the adjacent support piles 3, 3, and between the opposing third fasteners 13, a bracket 13 c that pivotally supports a bolt 13 b,
It arrange | positions so that the winch 13f with the reverse rotation prevention nail | claw 13e may oppose.
[0037]
Then, one end of the wire rope W is tied to the bolt 13b, and the other end is wound and tightened with a winch 13f.
Similarly to the fourth embodiment, the second rings 5b and 5b of the pair of root anchors 5 and 5 between the adjacent support piles 3 that are not connected by the same third fastener 13 are coaxially arranged. Side by side, a single long root member 4 is inserted between the two and spanned.
In this case, the support piles 3 are 12, but the root member 4 may be 6.
Since other configurations are the same as those in the above embodiment, the description thereof is omitted.
[0038]
In addition, although the supporting structure of the planted tree of 3rd Example to 6th Example demonstrated all the cases where the fastening member for temporary fastening and the fastening member for final fastening were used, the fastening member for temporary fastening is used. The same applies to the case where only the fastening member is used without using it, and the description thereof is omitted.
[0039]
In the said Example, although the 1st-5th fastener was illustrated, the structure of a fastener is not restricted to these, It is using the well-known structure which pulls linear materials, such as a wire rope, and clamps a support pile. it can.
Moreover, in the said Example, although a root anchor attachment tool and a fastener are driven after driving a support pile, in this invention, a root anchor attachment and / or a fastener are attached to a support pile beforehand. It may be what is being done.
[0040]
Further, when the fastening member is used for final fastening and temporary fastening, the fastening tools used for both may be the same or different.
Moreover, you may use the fastener of the structure which is easy to remove from support piles, such as a cap type, only for temporary fastening.
Further, the number of support piles driven in along the root pot is not limited to the embodiment, and can be appropriately changed according to the size and support strength of the root pot, and the wire rope is tightened by the tightening member. The method can also be changed as appropriate according to the number and arrangement of support piles.
[0041]
Moreover, the fastening member for temporary fastening and the fastening member for final fastening may be fixed to a support pile, or may be temporarily latched until it is held and tightened by an operator's hand.
For example, the structure which only tightens a support pile along a root pot only with a wire rope may be sufficient.
Similarly, the root anchor fitting is not limited to the structure of the embodiment as long as the root anchor is connected to the support pile in a state where the root anchor is turned sideways.
In addition, it goes without saying that various design changes can be made without departing from the scope of the present invention.
[0042]
【The invention's effect】
In the planted tree support structure according to the present invention, a root anchor is provided on the support pile, and a wooden root anchor member is attached as an anchor and embedded in the ground. Therefore, the tightening member is tightened so as to surround the root pot. Since the support pile thus made can increase the pullout strength and the support strength of the root pot, it can be supported regardless of the size of the root pot.
Moreover, since the root anchor member used as a support pile or an anchor is wooden, since it is returned to soil in the ground after the root pot has rooted, there is no risk of damaging the environment.
Furthermore, when cutting the upper part of a support pile and using it as a root member, it is not necessary to prepare a root member in advance and there is no waste.
And if the supporting pile is buried in the ground, a strong underground strut with a simple structure can be realized at low cost, which is extremely beneficial.
