Description

  The present invention relates to a column technology used in fields such as agriculture, forestry, and landscaping.

  When growing vegetables such as eggplant, tomatoes and peppers in the field, in addition to the supporting force that can withstand wind and rain, the supporting force that can withstand the weight of the crop (harvest) is required. In a typical field, vegetables are planted in the field baskets and struts are also inserted into the fences. Commercially available struts with warts are often used as struts. The vines in the field are fertile and soft, and it is labor intensive to insert the wart props manually and the support effect is not sufficient. If the prop is tilted, the harvest will come into contact with the ground, causing pest and rot damage.

The soil quality of fields and mountain forests varies greatly depending on the composition of clay, sand, pebbles, moisture, etc. For this reason, since the ease of driving when the column is raised or the holding force after the column is greatly changed, an auxiliary tool for assisting the column has been developed.
For example, the fixed pile which dug the hole so that the support | pillar for gardening can be inserted is proposed (patent document 1). If the fixed pile of Patent Document 1 is driven into a fence, and the horticultural support is inserted into the hole of the fixed pile, the soil will loosen like a fence after it has been raining compared to the case where only the horticultural support is inserted into the fence. However, the gardening support is less likely to collapse.

  In addition, there has been proposed a fixing device for preventing a column from falling down, in which a plurality of blades along the axial direction are radially provided on the outer periphery of a cylindrical body that allows the column to pass through (Patent Document 2). By allowing the column to penetrate the column and driving the column into the ground, the cylinder is driven along the column to prevent the column from falling due to the resistance of the blades.

On the other hand, damage to birds and beasts in forests and fields throughout Japan has been increasing in recent years. According to the Forestry Agency documents, the area of forest damage caused by wild birds and beasts such as deer and bears has reached approximately 9000 hectares nationwide in FY2014. In particular, about 80% of the damage caused by deer caused by foliage and debarking is a serious situation.
In the afforested area after logging, wild deer prefers to eat the shoots of young trees and eats the skin of the trunk. FIG. 11 shows an operation of setting up a support column 3 for stretching a protective fence 2 around a young planted tree 1 that deer likes and eats branches and leaves.

As shown in FIG. 11, the worker 5 inserts the support column 3 into the ground by using a special tool called the “Kakeya 4” and applying weight while standing by human power.
In the case of a mountain forest, the deer jumps over a slope of 1.5m without running up, so there is a strut with a total length of 2.1m that has a depth of 0.4m and a ground height of 1.7m. used.

Utility Model Registration No. 3047706 JP-A-7-264937

  In the pile described in Patent Document 1, since the hole into which the column is inserted does not penetrate the fixed pile, the supporting force is only due to the fixed pile. As a result, the field of soft soil is still lacking in support.

  Since the fixing device for preventing the collapse of the column described in Patent Document 2 has a complicated shape in which a plurality of blades along the axial direction are provided radially on the outer periphery of the cylindrical body, the number of parts is large and it takes time and effort to manufacture. In addition, because the fixing device for preventing the collapse of the support column and the support column are combined in advance and driven into the ground, it is difficult to drive the cylinder because the support column becomes an obstacle.

The support for the bird and animal guard fence shown in FIG. 11 is driven by bending and stretching exercises using both body weights and raising the hands up from the necessity of hitting a long support pole of 2.1 m with KAKEYA. there were. In the mountain forest, because the ground was soft and the tip of the support hit the rock, the average support capacity of the support could not be obtained, so the support was tilted and collapsed frequently.
In mountainous areas where birds and beasts are frequently damaged, there are many elderly farmers, and the burden of working such as driving high struts and reworking was enormous.

  In view of this, the present invention provides a socket pile that is a column auxiliary member capable of obtaining a stable column supporting force in a field. In addition, a support structure for a bird and animal guard fence that uses the socket pile and is excellent in workability and supportability is provided. Furthermore, it aims also at providing a driving jig for the socket pile.

The socket pile of the present invention is a socket pile provided with a through hole at the axis center of the pile having a conical or pyramidal lower end, and driven the socket pile from the ground to the ground, penetrating the column through the through hole, Furthermore, the support structure by the support | pillar is comprised by driving a support | pillar in the ground.

And the support | pillar structure of this invention is characterized by the cross section of a socket pile and a support | pillar main body being square or circular.
Furthermore, the column structure of the present invention is characterized in that the material of the socket pile and column body is wood or plastic.

The socket pile driving jig of the present invention has a core rod which is smaller in diameter than the through hole of the socket pile and has the same length as or slightly longer than the socket pile, and an upper end surface of the socket pile formed integrally with the core rod on the upper portion of the core rod. A socket pile with a driving jig that combines the socket pile and the driving jig by inserting the core rod of the driving jig into the through hole of the socket pile from above. The socket pile with a driving jig is driven from the ground into the ground by applying a striking force to the head of the head, and then the driving jig is pulled out from the socket pile.
The core rod and head material of the socket pile driving jig according to the present invention are iron or stainless steel.

  Since the socket pile of the present invention is a pile having one end of a cone or a pyramid and a through hole provided at the center of the shaft, only the socket pile is first driven from the ground into the ground with a hammer or the like when standing upright. Can do. Next, the support pillars are constructed by penetrating the support pillars through the socket holes and then driving the support pillars into the ground, so the support force of the support pillars is added to the support force of the socket piles, providing stronger support than before. You can gain power.

In the column structure of the present invention, when the column structure is erected, only the socket pile can be easily driven from the ground to the ground with a hammer or the like. Since the socket pile is a part of the entire support structure and is short, the driving operation is excellent in workability and can be easily performed even by an elderly person. By using a socket pile driving jig, the driving workability is further improved.
Next, the rebar that is longer than the socket pile is passed through the through hole of the socket pile, and the rebar is driven into the ground with a hammer, etc., so that the support force of the rebar is added to the support force of the socket pile for strong support. You can gain power.
Furthermore, a long column main body can be easily erected by fitting a hole of the column main body into a reinforcing bar erected upward.

Since the cross-section of the socket pile and the column main body of the present invention is square or circular, the cross-sectional shape can be easily formed and the workability is excellent.
In addition, since the material of the socket pile and the column main body of the present invention is wood or plastic, it is excellent in availability and can be manufactured at low cost.

The socket pile driving jig of the present invention is a socket pile with a driving jig in which the socket pile and the driving jig are combined by inserting the core rod of the driving jig into the through hole of the socket pile from above. Since the socket pile with a driving jig is driven from the ground into the ground by applying a striking force to the head of the socket, the upper end surface or the lower end of the socket pile is not damaged by hammering or contact with the earth and sand.
Moreover, since earth and sand do not penetrate | invade into the through-hole of a socket pile when a driving jig is used, the insertion of a support | pillar or a reinforcing bar after driving a socket pile can be performed easily.
Furthermore, when the core rod is longer than the socket pile, it is possible to easily insert the column or the reinforcing bar into the hole made in the soil after the core rod is pulled out.
Since the core material of the driving jig and the material of the head are iron or stainless steel, it is excellent in terms of availability and workability, and has good compatibility with wood or plastic material socket piles at the time of driving. The durability in case is also excellent.

FIG. 1 shows a front view (a) and a bottom view (b) of a socket pile 8 according to the present invention.
As shown in FIG. 1, the socket pile 8 has a square cross section and a relatively short column shape. The lower end of the socket pile 8 shown in FIG. 1 (a) has a quadrangular pyramid shape. A through hole 11 having a circular cross section is provided at the axial center of the socket pile 8.

The material of the socket pile 8 is wood, and is manufactured using thinned wood from a planted mountain forest. By using wood, it can be gradually decayed and returned to the soil while it is being used as a pile. In that respect, it will be carbon neutral and earth-friendly technology.
Moreover, waste plastic can also be used as the material of the socket pile 8. In this case, it is assumed that it is always collected, but this is an effective technique in terms of resource reuse.
Furthermore, even if the diameter of the support combined with the socket pile 8 is larger than the diameter of the through hole 11, if the material is wood or plastic, the hole diameter can be easily adjusted with a woodworking drill or the like.

FIG. 2 is a diagram showing an operation of driving the socket pile 8 according to the present invention into the flange 7.
The upper end 12 of the socket pile 8 is hit with a hammer 13 so that the lower end 10 of the quadrangular pyramid shape of the socket pile 8 bites into the soil.
Since the socket pile 8 is short, the hammer 13 for hitting the upper end 12 of the socket pile 8 may be a general one. In addition, since it is driven in the sitting position, the socket pile 8 can be driven into the rod 7 with little effort.

FIG. 3 shows a support structure by the pillar 14 in which the pillar 14 is penetrated into the socket pile 8 according to the present invention and then the pillar 14 is driven into the soil by 5 to 10 cm. In addition, as the support | pillar 14, the support | pillar with a wart commercially available is used.
The support structure of the column 14 by the socket pile 8 of the present invention shown in FIG. 3 is not a method of inserting or filling the socket pile 8 into the soil after the socket pile 8 is mounted on the column 14, but driving the socket pile 8 alone. After that, it is excellent in terms of workability (working posture and labor reduction) because it is a method of inserting the support 14.

  The eggplant 15 planted in the basket 7 and the column 14 are connected by a string 16. The support structure in which the socket pile 8 and the column 14 shown in FIG. 3 are combined has a contact area with the soil 3 to 5 times that of the column 14 alone, so that the support performance is dramatically improved.

In addition, columns such as vegetables, fruit trees, flowers, etc. are collected every time after harvesting, but the socket pile 8 of the present invention is easy to collect because the upper end 12 is exposed from the soil, and the soil surface is roughened. Nor.
In addition, the socket pile 8 of this invention can be utilized also as a pillar part support material of a greenhouse, and can show a big effect at the point of workability | operativity improvement and the increase in a supporting force.

FIG. 4 is a diagram showing an operation of driving the socket pile 8 having a support structure according to the present invention onto a slope in a mountainous area. The upper end 12 of the socket pile 8 is hit with a hammer 13 so that the lower end 10 of the quadrangular pyramid shape of the socket pile 8 bites into the soil. The socket pile has a length of 30 cm and a cross-sectional dimension of 45 mm × 45 mm.
The socket pile 8 may be driven up to the full slope 20 or, if the soil is hard, it may be driven in a possible range (for example, about 20 cm).
Note that when the soil is rocky and very hard, the socket pile 8 may not be used, and only the reinforcing bars described later may be directly driven.

FIG. 5 is a diagram illustrating an operation of penetrating the reinforcing bar 21 into the socket pile 8 having the support structure according to the present invention and driving the reinforcing bar 21 into the soil.
The reinforcing bar 21 has a nominal diameter D-13 and a length of 60 cm. As shown in FIG. 5, the reinforcing bar 21 is driven so that its upper portion 15 cm remains above the upper end 12 of the socket pile 8.

FIG. 6 is a diagram for completing the column structure 24 by fitting the hole 23 of the column main body 22 to the reinforcing bar 21 erected upward.
The column main body 22 shown in FIG. 6 is a prism having a cross section of 45 mm × 45 mm and a length of 170 cm. As the material of the column main body, the same wood or plastic as the socket pile 8 is used.
A hole 23 into which the reinforcing bar 21 is fitted is provided at the lower end of the column main body 22 at the center of the shaft. As the depth of the hole 23, a dimension (about 20 cm) slightly longer than the protruding length of the reinforcing bar 21 protruding from the upper end 12 of the socket pile 8 is adopted. The inner diameter of the hole 23 is slightly larger than the outer diameter of the reinforcing bar 21 (about 14 mm).

  The strut structure 24 of the present invention shown in FIG. 6 shoots the socket pile 8 and the reinforcing bar 21 with a hammer in a sitting position, so that the labor and workability are reduced as compared with the conventional hammering 4 shown in FIG. Will greatly improve. In addition, since the reinforcing bars 21 are excellent in penetrating force to rocks and the like, it is possible to erect the strut structure on the ground that could not be installed conventionally.

Since the support structure 24 shown in FIG. 6 has a large ground contact area by using the socket pile 8, a large supporting force is ensured even if the ground surface is soft ground. Moreover, since the reinforcing bar 21 is excellent in penetration force into the soil, the reinforcing bar 21 has a sufficient driving depth, and the reinforcing bar 21 and the socket pile 8 exhibit a synergistic effect to obtain a large support force.
In addition, the column main body 22 used as a deer-avoidance protective fence column after being erected is subject to a pulling force and a compressive force from side to side due to wind and snow, but the wood, plastic, reinforcing bar used in the column structure of the present invention. Both of them have flexibility, so they can absorb the load and the support performance does not deteriorate.

FIG. 7 shows a deer avoidance protection fence 25 using the support structure 24 according to the present invention.
In order to protect the planted young tree 1, the column structure 24 according to the present invention is erected every 2 to 3 m. A fiber fence or a wire mesh is hung on the support structure 24 to complete the protective fence 25. The deer 26 cannot access the planted young tree 1 because of the protective fence 25 and cannot eat the planted young tree 1.

Conventionally, the net used as the protective fence 25 is often made of fiber or metal. However, metal nets are heavy and burdensome in the forest, so they are shunned. In large fiber meshes, deer horns get tangled and die, and in recent years, fine mesh fiber nets tend to be used frequently. However, when using a net with fine meshes, the weight of the net and the pressure of wind and snow, rock rolling, etc. frequently cause tilting, falling, and folding of the pillars, requiring regular repairs.
However, since the column structure 24 of the present invention has the configuration shown in FIG. 6, it can be easily repaired by replacing only the column body 22, and is excellent in terms of repair workability.

As shown in FIG. 7, a large number of support structures 24 are required for the protective fence 25 surrounding the planted young tree 1. Further, since the area of the forest to be planted is vast, it is necessary to erect a very large number of support structures 24 as a whole area.
Since the strut structure 24 of the present invention can use locally produced timber for local production and consumption, it can contribute to the activation of local industries. Furthermore, as described above, since it can be safely erected with a small amount of labor, the labor force in an aging mountainous area can be effectively utilized. Moreover, since the socket pile 8 and the reinforcing bar 21 are excellent in supporting force, the repair frequency is reduced and the repair burden can be reduced. From the above, it becomes a very effective technique against the increasing damage to birds and animals in recent years.
