Detailed Description of the Invention

[0001]

[Industrial field of application] The present invention, when planting a tree whose roots are rather root-wrapped, causes a risk of being easily lodged by strong winds for a while from immediately after planting until rooting. In order to prevent the conventional means that tied the upper part of the tree and the surface part in several directions by splints to prevent it, while eliminating the waste of the surrounding space required for splints,
This is a method for embedding tree planting in which splints are eliminated and the lodging is prevented by strengthening only the roots embedded in the ground.

2. Description of the Related Art The prior art according to the present invention is shown in FIG.
As shown in the side view of FIG. 2 and the plan view of FIG. 13, first, an implantation hole having a diameter larger than the outer circumference of the root winding portion 3 considering the required depth and working space for the root winding portion 3 of the tree 2 with respect to the ground surface portion. 1 is excavated, and at a portion corresponding to the outer peripheral surface of the root winding portion 3 on the bottom of the hole of the implantation hole 1,
Anchors 4 are placed at approximately four equal points of the neck winding part 3,
An upper pulling rod 5 extending above the anchor 4 is exposed on the bottom surface of the hole for a required length, and a root winding portion 3 is inserted thereinto and a wire rope 6 is used to hold the anchor 4 from the upper side of the root winding portion 3 and the respective anchors 4. We are going to combine them and tighten them.

However, the root winding portion 3 is a flexible body to a certain extent because the root and the soil are simply bound together with the soil, etc., so that the wire rope 6 bites into it and cannot be tightened sufficiently. The wire rope 6 is tightened through a pressure resistant material such as a plate, and the implantation hole is backfilled to achieve its purpose.

[0004]

The prior art described above has many drawbacks pointed out. First, the wire ropes 6 are connected to the opposite anchors 4 to cover the root winding. The bottom surface of the root winding part 3 is a circular peripheral surface having a shape like a pan bottom, and the upper pulling rod of the anchor 4 is generally round steel with a diameter of 9 mm. It can withstand enough, but it easily bends against lateral pressure.

Therefore, when tightening the wire rope 6, unless it is tightened evenly and gradually with respect to the anchors 4 on both sides, it will be inclined to one of the two sides.
The upward pulling rod 5 which is ineffective against the lateral pressure cannot hold it down, and a considerable skill is required for the tightening procedure.

In the prior art, as shown in FIG. 14, for example, when the tree 2 tries to fall in the P direction due to strong wind or the like,
The root winding portion 3 in the ground moves in the X direction as indicated by the dotted line, but this is a rotational movement in the N direction with the point M as a fulcrum.

However, for the N direction, the anchor 4A
Since the transfer is stopped by this, the pressing force on the fulcrum M is unavoidably strong, but since the point M, which is the fulcrum, is simply a bundle of hair root and soil mixture, etc. However, the tree 2 is relatively easily deformed in the P direction without the meaning of the original immovable fulcrum, because it is relatively easily deformed and the soil receiving it is also easily deformed. It will end up.

Also, the anchor 4 used for this exerts sufficient proof strength against the upward pulling load force, but since it is completely helpless against the pressing force against the ground, it is against the collapse in the P direction. The anchor 4B has no effect, and the anchor 4A bears most of its mission. In this case, the anchors 4C and 4D on both sides have a very small amount of almost powerlessness, which is extremely unstable as a measure to prevent lodging. I have to say that.

The ideal idea here is that the anchors constructed in four directions are desired to exert their proof strength in all four directions together with the root winding part 3 in any fall direction. Will have to wait.

[0010]

The drawback of the prior art is that the anchors 4 placed from the bottom of the implantation hole 1 can withstand the upward pulling load on the surface of the earth, but with respect to the pressing force against the ground. In other words, it is completely powerless, and no protection work is done on the outer peripheral surface of the raised neck winding portion 3.

In order to solve this conventional deficiency, the present invention has a direction of approximately 4 equal parts from the central portion of the implantation hole 1 excavated to have a diameter slightly larger than the diameter of the root winding portion 3 for planting. In the future, the case where the neckwrap part 3 is placed in the center of the implantation hole 1 in the future is measured, and it is in close contact with any one of the four equal directions and the outer surface of the neckwrap part in the direction adjacent to it. The stationary plate 8 is placed at two locations to form the first stationary plate 8A and the second stationary plate 8B, and the first stationary plate 8A has the first resistance plate 11A and the second stationary plate 8B has the second stationary plate 8B. The second resistance plates 11B are respectively fitted and driven, and the remaining two directions are separated from the outer peripheral surface of the future root winding part 3, and only the stationary plate 8 is stationary, and the stationary plate 8 is fixed to the third stationary plate. 8C and the fourth stationary plate 8D, then the root winding part 3 is implanted in the implantation hole, and the outer peripheral surface is closely contacted with the first stationary plate 8A and the second stationary plate 8B, and then, Closely allowed each to Nemaki unit 3 moved a stationary plate 8C and fourth stationary plate 8D, these third
The third resistance plate 11C and the fourth resistance plate 11D are placed on the stationary plate 8C and the fourth stationary plate 8D, respectively, and thus the outer peripheral surfaces of the root winding portion 3 in the quadrant direction are respectively fixed plates 8A, 8
B8C and 8D are closely surrounded, and the main wire rope 15 is commonly passed through the engaging rings 13 of the respective resistance plates 11A, 11B, 11C and 11D, and the main wire rope 15 is sufficiently tightly coupled. Characterized by the stationary planting of trees.

Further, with the main wire rope 15 sufficiently tightly connected, a circular pressure-resistant material 16 is further placed on the upper side of the root winding portion 3, and the circular pressure-resistant material 16 and the respective resistance plates 11A, 11B, 11C. , 11D between the main wire rope 15 and the main wire rope 15 may be tightly connected by the tightening rope 17 to set the tree planting.

Further, the resistance plates 11A, 11B, 11
The main wire rope 15 is commonly passed through the engaging rings 13 of C and 11D.
The pressure resistant material 7 may be interposed between the root wrap portion 3 and the main wire rope 15 when they are fastened. Further, the resistance plates 11A, 11B, 11C, 11
When the main wire rope 15 is commonly passed through the engaging ring 13 of D and the main wire rope 15 is tightly coupled, the root winding portion 3 and the main wire rope 1
The pressure resistant material 7 may not be interposed between the five.

FUNCTION AND EXAMPLE The present invention will be described below.
First, referring to the side view of FIG. 1 and the plan view of FIG. 2, this is a slender steel plate having a predetermined width and length which is bent to form a rising surface and a flat plate surface 9, and on the flat plate surface 9, a triangular fixed shape as shown in the figure is set. The stationary plate 8 is configured by fixing the ring 10.

Next, as shown in the side view of FIG. 3 and FIG.
The resistance plate 11 is made of an elongated steel plate having a predetermined width and length, the center line on the length is extruded to form the rib 12, and the entire length is a perfect circle having a predetermined curvature on the extrusion side of the rib 12. The rib 12 is curved, and the impact plate 14 is fixed to the inside of the central portion of the rib 12 in the lengthwise direction, and the engaging ring 13 is fixed to the outer arc surface of the rear end of the rib 12. .

As shown in FIG. 5, the stationary plate 8 and the resistance plate 11 have the stationary plate 8 stationary on the bottom of the implantation hole 1, and then the resistance plate 11 is inserted into the stationary ring 10 to form a curved flat plate. In the state where the surface is raised and closely contacted with the rising surface, first, a dedicated tool is fitted into the hitting plate 14 and placed, and as the hitting plate 14 is submerged in the ground, the rear end portion is hit next time. It is carried out so that the casting is finished when the rear end portion is aligned with the upper side of the rising surface.

The following is a description of the method of implementing the present invention. As shown in FIG. 6, a slightly large square-shaped planting hole 1 is excavated corresponding to the root winding portion 3 and a circular shape in which the root winding portion 3 should be placed in the future. For example, the first stationary plate 8A and the second stationary plate 8B are placed at two adjacent four-divided points at the planned positions indicated by the dotted lines, and the first resistance plate 11A and the second resistance plate 11B are struck on each of them. Set up.

Subsequently, the third stationary plate 8C and the fourth stationary plate 8D
Is located so as to be separated from the expected position of the root winding portion 3 and to contact the side wall of the implantation hole 1.

When the root winding portion 3 is implanted in this state,
Since the third stationary plate 8C and the fourth stationary plate 8D are separated from the planned position, the root winding part 3 can be implanted at the planned position without any interference.

Thus, the neck wrap portion 3 is connected to the first stationary plate 8A and the second stationary plate 8A.
If it is placed in close contact with the stationary plate 8B and implanted, here, FIG.
As shown in FIG. 8, the third stationary plate 8C and the fourth stationary plate 8D are pressed so as to be in close contact with the root winding part 3 as shown in FIG.
The third resistance plate 11C is mounted on the base plate, and the fourth resistance plate 11D is mounted on the fourth stationary plate 8D (see FIG. 9). The outer side surfaces of the portion 3 in the four directions are surrounded and closely contacted with each other, and the stationary plate 8 is surely immobilized by the respective resistance plates 11. With more roots than the bottom, this is a stronger, more upright posture than it was completely rooted.

In order to further strengthen the present invention, as shown in the plan view of FIG. 10 and the side view of FIG. 11, a main wire rope 15 is commonly passed through the engaging ring 13 of each resistance plate 11, The pressure resistant material 7 is interposed between the main wire rope 15 and the root winding portion in contact with the main wire rope 15, and both ends of the pressure resistant material 7 are tightened at any one position.
Since 1 is a strong support placed in the ground, there is no fear that it will move to either side by tightening the main wire rope 15, and it is sufficient to simply tighten it, so there is no particular need for learning. Further, if necessary, a circular pressure-resistant material 16 is attached to the upper side of the neckwrap portion, and the circular pressure-resistant material 16 and each anchor 11 and the main wire rope 15 between the anchors 11 are securely tightened by a tightening rope 17. Then, the lodging strength is further enhanced.

[0022]

According to the present invention, by closely contacting the four side surfaces of the root winding portion 3 with the stationary plate 8 and the resistance plate 11, it is possible to form a state in which Taiki is rooted. Is not the one who fulfills the proof stress mission by itself, but tightens the four resistance plates and the root winding part 3 integrally with the main wire rope 15 and further strengthens this with circular pressure resistant material and tightening rope. Since it is fixed, the yield strength is even stronger. Furthermore, no proficiency is required for its implementation, and the operation is extremely quick and easy.
