Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a fall protection fence.

[0002]

2. Description of the Related Art Conventionally, when a steep slope is generated on a hillside due to road construction or land development, there is a possibility that falling objects such as topsoil, stones and rocks may be caused by the collapse of the steep slope. In addition, there is a risk of avalanches due to collapsed snow in winter in hillsides having steep slopes. For this reason,
Conventionally, as a part of ground construction on steep slopes, residential areas and roads, steel fallen object fences generally called rock fall fences are installed in appropriate places on steep slopes such as hillsides,
By installing a fall protection fence, generally called a stone guard, between a steep slope and a flat surface, a roughly contoured receiving wall was formed.

Also, waste tires as interference materials are arranged side by side on the receiving wall so that the impact of a falling object such as a heavy rock or an avalanche is not directly applied to the receiving wall, and the receiving wall is not damaged. Things have also been done. That is, an attempt has been made to absorb the impact of a falling object by effectively utilizing the elasticity of a waste tire that is currently difficult to dispose.

[0004]

However, since there are many tire size standards, there is a problem that the size of waste tires varies and it is difficult to obtain uniform materials. If the size of the waste tires is not uniform, there is a problem that the strength as a cushioning material cannot be sufficiently secured even if the waste tires are arranged side by side. That is, since the falling object first hits a larger waste tire than the others, the impact may be concentrated in one place. Furthermore, since the connection between the waste tires is small, most of the impact of the falling object colliding with one waste tire is absorbed by the waste tire alone, so that sufficient strength as a cushioning material cannot be secured.

In addition, since the waste tire is directly attached to the receiving wall, if the falling object passes through a through hole formed in the center of the tire, the falling object may directly contact the receiving wall. In some cases, it was not possible to completely respond to falling rocks. In addition, the accumulation of water in the waste tire may cause the occurrence of insects such as mosquitoes.

In other words, as an example of an effective method of using waste tires that are difficult to dispose of, use of the tire as a cushioning material for a fence for protecting falling objects has been attempted. However, the performance of waste tires can still be sufficiently exhibited. And it was not a perfect technology in this regard.

[0007] The present invention has been made in consideration of the above-mentioned matters, and an object of the present invention is to use more waste tires effectively and to suppress the impact due to a falling object on a sloped ground by using the characteristics of the waste tires. An object of the present invention is to provide a fallen object protection fence capable of protecting a fallen object more firmly by avoiding damage to a receiving wall surface by the fallen object.

[0008]

In order to achieve the above object, a fallen object protection fence according to the present invention is provided at a slope on a slope or a position adjacent to a slope of a slope to prevent fall of a fallen object. The fence is characterized by having a protection fence main body and a tire cushioning material formed by processing a plurality of waste tires into a plate shape and disposed on a mountain side of the protection fence main body.

According to the above invention, the impact of a falling object on an inclined ground can be absorbed by effectively using the characteristics of the waste tire, and the fall of the protective fence body by the falling object can be avoided, so that a stronger falling object can be obtained. Protection can be provided. Also, since the tire cushioning material is made by processing waste tires into a plate shape, the size of the tire cushioning material can be made uniform, and the cushioning material does not receive partial pressure due to the difference in thickness of the tire cushioning material. Sufficient strength can be secured.

In addition, through holes and puddles do not occur due to the unique shape of the tire cushioning material,
Its functionality can be improved. That is, the performance of the waste tire can be maximized and the waste tire can be effectively used.

Further, since the tire cushioning material can not only absorb the impact due to the collision of stones or rocks, but also obtain the effect of absorbing noise, the soundproofing effect can be added to the fallen object protection fence. In addition, it is possible to prevent the noise generated from roads from threatening ecosystems such as animals living in mountains. And since it can be formed at extremely low cost, a falling object protection fence having a sufficient height can be formed, whereby the protection from falling objects can be more reliably performed, and the soundproofing effect can be further improved.

When the tire cushioning material is a compressed structure of a tire formed by compressing a plurality of waste tires and binding the compressed waste tires, it is possible to reduce the energy cost as much as possible and to increase the number of waste tires. There are advantages that can be used effectively.

[0013]

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment using a fallen object protection fence of the present invention. In FIG. 1, reference numeral 1 denotes a fall protection fence installed between a slope of a slope formed on a hillside and a flat surface such as a road W, which is generally called a stone guard. The stone guard 1 receives falling objects such as topsoil, stones S and rocks R which may be caused by the collapse of the sloped land so as not to enter the road W or the residential area.

Reference numeral 2 denotes a fallen object protection fence disposed on the slope of the slope, which is generally called a rockfall protection fence.
In addition, this rock fall protection fence is designed to catch falling objects such as topsoil, stones S and rocks R in addition to avalanches caused by snow that has collapsed in winter at an early stage to minimize the damage and to minimize damage. Take it.

Each of these fallen object protection fences 1 and 2 has a plurality of wires 3a and 4a attached to pillar piles 3b and 4b having sufficient strength, such as steel, for example.
4 and receiving wall surfaces 1a and 2a formed by tire cushioning members 5 closely arranged on the mountain side (sloped ground side) of the protective fence bodies 3 and 4. The tire cushioning member 5 is, for example, a tire compression structure formed by binding a compressed waste tire obtained by compressing a waste tire. The receiving wall surfaces 1a and 2a may have a rigid net material such as expanded metal.

2 and 3 are enlarged views of the configuration of the stone guard 1. FIG. 2 is a longitudinal sectional view, and FIG. 3 is a horizontal sectional view.

As shown in FIGS. 2 and 3, the pillar pile 3b is buried in a retaining wall 6 made of, for example, concrete formed between the slope of the sloping ground and a flat surface, and is erected almost vertically. It is made of H-shaped steel and has a height of, for example, about 1.5 to 2.5 m. And, in the center of each pillar pile 3b, a pillar pile 3
The protective fence main body 3 is formed between the pillars 3b by penetrating a plurality of wires 3a connecting the b to each other. The pillar 3b and the wire 3a are preferably made of steel in order to secure the strength as the protective fence main body 3, but the present invention does not limit the material and size. Needless to say, the shape can be any shape known as a general stone guard.

The tire cushioning material 5 constituting the receiving wall 1a is, for example, a tire compression structure formed by binding a compressed waste tire obtained by compressing a discarded waste tire. Regarding the manufacturing method and its processing apparatus, the applicant of the present invention proposed in Japanese Patent Application No. 11-285675 "a method for processing waste tires, a method for forming waste tire compression structures, fishing reefs, a method for forming embankment bases, Waste tire processing apparatus "can be used.

FIG. 4 is a view showing an example of a method of forming the tire cushioning material 5. In FIG. 4, reference numeral 10 denotes a vertical compressor, which includes a compression plate 11 for compressing the waste tire t, a hydraulic cylinder 12 for vertically moving the compression plate 11, and a waste tire t.
, A loading port 14 for the waste tire t provided on the horizontal plate 13, and a stopper claw 15 for preventing the compressed waste tire t from floating.

As shown in FIG. 4 (A), a waste tire t is loaded from the loading port 14 with the horizontal plate 13 closed.
By compressing the waste tire t with the hydraulic cylinder 12, the compressed waste tire T compressed to a volume of about 20%
Can be formed. Then, as shown in FIG. 4 (B), in a state where the compressed waste tire T is compressed by the compression plate 11, the wire 16 is bound so as to surround the compressed waste tire T, and the compression by the compression plate 11 is released. As shown in FIG. 4 (C), a substantially plate-shaped tire compression structure 5 (tire cushioning material) tied up by the wire 16 can be formed.

By forming the substantially plate-shaped tire cushioning material 5 as described above, a large amount of waste tires can be effectively used without increasing the energy cost as much as possible. The work is very easy and the processing work can be done quickly.

FIG. 5 is a perspective view showing an example of a method of attaching the tire cushioning material 5. As shown in FIG. In this embodiment, mounting members 5a made of substantially metal sheet are arranged on both front and back sides of the tire cushioning material 5. 5B, the bolt 5b is inserted into the tire cushioning material 5 while passing through a mounting hole H formed at an appropriate position of a mounting member 5a disposed on one surface side of the tire cushioning material 5. The mounting member 5a is pierced, passed through the corresponding mounting hole H 'of the mounting member 5a arranged on the other surface side, and tightened by the nut 5c, thereby fixing the mounting member 5a to the tire cushioning material 5.

As described above, the tire cushioning material 5 to which the mounting member 5a is fixed is connected to the tire cushioning material 5 via the mounting member 5a.
It can be easily attached to the wire 3a. That is, as shown in FIG. 5 (A), by fixing the washer 5d to the mounting member 5a using screws 5e or the like with the washer 5d sandwiching the wire 3a, the tire cushioning material 5 is attached to the wire 3a. On the other hand, the protective fence body 3 can be securely attached, thereby protecting the protective fence body 3 from the impact due to the collision of the falling object.

By forming the stone guard 1 of the present embodiment on the upper portion of the retaining wall 6 as shown in a vertical sectional view in FIG. 2, even if an unexpected falling object is generated, it can be dealt with. be able to. That is, a space A as shown in FIG. 2 is usually formed between the inclined surface and the retaining wall 6, and small falling objects such as stones S and sand are accumulated in the space A. However, a falling object (a large amount of stone S
Or a large rock R), it is possible to prevent falling objects from entering the road W within the range of the height of the receiving wall surface 1a.

Even if the object is a large falling object such as a rock R, the impact of the collision can be absorbed by the tire cushioning material 5, so that the protective fence body 3 can be protected from being damaged by the falling object. Also, since the tire cushioning material 5 is made from waste tires that are in trouble for disposal,
The production cost is extremely low, and the construction cost can be reduced accordingly.

In addition, since the tire cushioning material 5 formed by processing a waste tire into a substantially plate shape can be uniform in thickness and the like, the construction is easy, and the substantially flat pressure receiving plane is provided. 5f can be formed. In other words, the force applied to a part of the tire cushioning material 5 is dispersed not only in one waste tire but also in the entire tire cushioning material 5, so that no local force is applied, and the cushioning performance is raised by that much, thereby improving safety. Performance can be further improved. In addition, since no puddles are formed when waste tires that are not processed are arranged, they do not cause breeding of pests such as mosquitoes.

FIG. 6 is a side view showing the structure of the fallen object protection fence 2. In FIG. 6, the column pile 4b is driven at an appropriate angle (an angle from a direction substantially perpendicular to a direction substantially perpendicular to the slope) with respect to the slope of the hillside so as to protect falling objects, for example, steel. And a plurality of piles are provided at predetermined intervals in a direction in which contour lines of the slope are drawn. Reference numeral 7 denotes a support pile driven into the slope on the valley side so as to support the column pile 4b, and 7a denotes an auxiliary pile for preventing displacement of the support pile 7, and the column pile 4b and the support pile 7 The auxiliary pile 7a and the support pile 7 are fixed by a connecting metal 7b, and are fixed by a connecting metal 7c.

Further, a plurality of wires 4a are penetrated in appropriate places of the pillar pile 4b to increase the strength of the protective fence body 4, and the tire cushioning material 5 is provided on the mountain side (slope side) of the wire 4a. Is fixed.

The tire cushioning member 5 is formed by binding a plurality of waste tires t obtained by compressing a plurality of waste tires t described in detail with reference to FIG. 4, for example. The method detailed in the description of 5 can be used. Since the fallen object protection fence 2 has the tire cushioning material 5 attached to the mountain side of the protection fence main body 4, the impact received when a fallen object collides can be effectively reduced, and the safety can be improved accordingly.

Further, by embedding the pillar pile 4b constituting the protective fence body 4 on the slope as in the present embodiment, the strength of the receiving wall surface 2a can be secured, and falling objects such as avalanches and rocks R can be quickly removed. It can be hard to stop. However, the present invention does not limit the configuration of the protective fence body 4 to the above-described shape.

FIG. 7 shows another example of the fallen object protection fence 2 '. In FIG. 7, reference numeral 8 denotes a protective fence main body made of, for example, a pipe made of steel and fixedly connected to a slope. A falling object protection fence 2 'having a receiving wall 2a is formed. In the following description, an example in which the protective fence main body 8 is formed using a pipe material is disclosed as an example, but it goes without saying that the protective fence main body 8 may be formed using a bar material or the like.

The protective fence body 8 is composed of a first pipe 8a made of a steel pipe bent in a Japanese style, and the first pipe 8a.
a, a plurality of second pipes 8b forming a receiving wall 2a for falling objects by attaching the tire cushioning material 5, and diagonally connected from both left and right upper ends of the first pipe 8a. A third pipe 8c for defining the angle of the receiving wall 2a, a fourth pipe 8d for increasing the strength by connecting the third pipe 8c to a substantially middle position in the longitudinal direction of the first pipe 8a, and the first pipe 8a. And a steel plate 8e provided with a hole Ah for inserting the anchor A and connected to the ground portion of the third pipe 8c.

It is preferable that these members 8a to 8e are welded in order to maintain their strength sufficiently, and it is desirable that the material is made of a metal such as steel having sufficient strength. By forming the size according to the size of the tire cushioning material 5, each fallen object protection fence 2 'can be grounded independently, thereby facilitating construction. As shown in the figure, it is also possible to arrange the falling object protection fences 2 'side by side to form a continuous receiving wall surface 2a so as to draw a contour line of a slope.

Since the fallen object protection fence 2 'of this embodiment has the protection fence main body 8 formed in advance, the labor required for construction can be reduced as much as possible. In addition, as shown by reference numeral 8f in the drawing, it is also possible to form a buried portion on the slope at the lower end of the first pipe 8a. With this configuration, the ground strength of the protective fence main body 8 is increased. be able to. In this case, the plate body 8 connected to the first pipe 8a
e may be omitted. That is, the angle of the receiving wall 2a can be adjusted by the length of the buried first pipe 8a. Further, the third pipe 8c and the fourth pipe 8
A hinge may be formed at the connecting portion J between d and the first pipe so that the protective fence body 8 can be folded during transportation.

In each of the examples described above, the tire cushioning material 5 is described as being formed by binding a compressed tire. However, the present invention is not limited to this, and the waste tire is processed into a substantially plate shape. Any form may be used. Next, a modified example of the tire cushioning material will be described.

FIG. 8 discloses another tire cushioning material 5 'as an example of a modification. The tire cushioning material 5 'of this example is a tire piece t' obtained by appropriately cutting waste tires in a bag body 9 formed by sewing a net made of synthetic resin fiber having durability and rigidity into a bag shape. The thickness limiting portions 9a are formed on both the front and back sides of the bag body 9 so that the overall shape is substantially plate-like. The size of the tire piece t 'may be larger than the mesh of the mesh forming the bag body 9;
It is sufficient if it is about m to several tens cm.

The size of the cushioning material 5 'having the above structure can be freely set according to the size of the bag 9, and the thickness of the cushioning material 5' can be adjusted according to the required cushioning performance. It can be formed freely. Further, the width and length can be set freely according to the size of the protective fence body 8 of the fallen object protective fences 1 and 2. In addition, since it does not become unnecessarily large, transportation becomes easy.

Further, the tire cushioning material 5 ′ is
When placed on the protective fence bodies 3 and 4 described above, the falling object first collides with the bag body 9, and the impact can be dispersed and received by the bag body 9 throughout the tire cushioning material 5 ′. Can be improved. Note that the bag 9 in the configuration of the tire cushioning material 5 'is not limited to being formed of a net made of synthetic resin fibers, and is formed by, for example, bending an expanded metal into a plate shape as a whole. The rigidity may be further improved as a box-shaped bag formed by the above method.

In each of the above-described examples, the present invention has been described as a method for attaching the tire cushioning material 5 to the protective fence bodies 3, 4, and 8 with reference to FIG. It goes without saying that the mounting method of the cushioning member 5 is not limited to the above-described example. That is, for example, a rod-shaped mounting member is tightly fixed to the tire cushioning members 5, 5 ', and the wires 3a, 4 are connected via the rod-shaped mounting member.
a. Further, the tire cushioning material 5 is directly connected to the wires 3a, 4a by a separate wire without using the above-mentioned attachment member.
a.

In any of the above-described examples, the provision of the tire cushioning members 5 and 5 'on the fallen object protection fences 1 and 2 not only absorbs the impact caused by the collision of the fallen object. , Can also absorb sound waves. Therefore, it is also possible to provide a soundproof wall at a low cost so that noise generated from the road W is prevented from entering a slope such as a forest as much as possible. Further, the present invention can be used as a soundproof wall regardless of the presence of a slope.

[0042]

As described in detail above, according to the fallen object protection fence of the present invention, the impact of a fallen object on an inclined ground can be absorbed by effectively utilizing the characteristics of the waste tire, and the body of the protection fence by the fallen object can be absorbed. By avoiding damage to the object, it is possible to provide stronger protection against falling objects. Also, since the tire cushioning material is made by processing waste tires, the size can be made uniform, and there is no partial pressure due to the difference in the thickness of the tire cushioning material, and the strength as a cushioning material Can be secured sufficiently.

Furthermore, through holes and puddles do not occur due to the unique shape of the tire cushioning material,
Its functionality can be improved. That is, the performance of the waste tire can be maximized and the waste tire can be effectively used. In addition, the tire cushioning material can absorb the impact due to the collision of stones and rocks, and can also obtain a noise absorbing effect, and can add a soundproofing effect to the fallen object protection fence.
And since it can be formed at very low cost, a fall protection fence of a sufficient height can be formed, whereby the protection from fallen objects can be performed more reliably.
