[Detailed description of the device]

[0001]

[Field of industrial use] The present invention relates to a ground construction material used when constructing a soil structure or an anti-earth pressure structure such as an embankment, a slope or a ground, and used as a so-called sandbag substitute. Is.

[0002]

2. Description of the Related Art New roads or slopes associated with them,
When constructing a reclaimed land or an embankment, it is necessary to carry out work such as embankment and backfilling, but these works are carried out by using a large amount of soil from which mountains have been shaved off. In addition, these earth structures must avoid large settlements, and must also prevent the embankment from being washed away by rain, etc. It was carried out by putting soil and crushed stone in a sandbag and arranging them in places where they were needed.

However, it is very troublesome to form a sandbag containing soil or crushed stone at a construction site, and the sandbags are heavy when carrying and arranging them. Therefore, it is very difficult. A particular problem is that when the sandbags containing soil and crushed stones as described above are used on so-called soft ground, these sandbags gradually sink,
It is the deformation of the ground and earth structures.

On the other hand, in recent years, various products have been produced in large quantities using synthetic resin materials such as polyethylene, polypropylene, polystyrene and vinyl chloride, and as a result, a large amount of waste materials called "waste plastic" have also appeared. There is. Of course, the synthetic resin products themselves are destined to become "waste plastic" as a result of being used. Although these waste plastics are burned and processed,
This treatment has already reached its limit, and developing another treatment method for waste plastic has become an urgent task.

When considering the above situation, the present inventor has found that the above waste plastics can be reused for earth structures. Therefore, the present inventor has completed various aspects of the present invention as a result of various studies to make it concrete.

[0006]

[Problems to be Solved by the Invention] The present invention has been made on the basis of the above-described background. The problems to be solved are the difficulty of working when constructing an earth structure and the treatment of waste plastic. It is an increase.

The object of the present invention is to use waste plastic as a constituent material and to perform its treatment at the same time, and to construct a lightweight and highly rigid earth structure material. It is to provide a very excellent ground construction material with a simple structure.

[0008]

Means for Solving the Problems In order to solve the above problems, the means adopted by the present invention will be described with reference to the reference numerals used in the embodiments. The ground building material 10 is configured by accommodating a large number of the above-mentioned aggregates 13. The ground building bag 11 is formed of a material having excellent corrosion resistance such as synthetic resin, and
Is formed into a predetermined spherical or oval shape and is hollow, and a large number of convex portions 14 or concave portions are formed on the surface thereof.

[0009]

The operation of the ground building material 10 according to the present invention constructed as above will be described below together with the mode of use thereof.

First, in the ground building material 10, since the ground building bag 11 and each aggregate 13 are formed of a synthetic resin material that does not corrode even when buried in the soil, it has excellent corrosion resistance. It has become a thing. In particular, since the ground building material 10 is actually constructed in a state as shown in FIG. 2, it is not exposed directly to ultraviolet rays for a long time, and in that sense, it is durable. It is excellent.

Since the ground building material 10 contains a large number of aggregates 13 in the ground building bag 11,
It is natural that the aggregates 13 are not disassembled during transportation and construction, and the aggregates 13 are wrapped in the soil-construction bag 11 having excellent corrosion resistance. Therefore, the soil-construction material 10 is reused. It is possible to do so, and it is easy to dig up for that.

In addition, in the ground building material 10, the ground building bag 11 and the aggregate 13 are made of a material that is sufficiently lighter than crushed stone, and the inside of each aggregate 13 as well as between each aggregate 13 is Since it is hollow, the total weight is very small, at least 1/10 or less, as compared with the sandbag containing soil or crushed stone. Therefore, the transportation and arrangement work of the ground construction material 10 can be performed very easily.

Further, since each aggregate 13 has an outer shape based on a spherical shape or an oval shape, when no force is applied from above, as immediately after the arrangement at the construction site, Even if each aggregate 13 has the convex portion 14, it can move to some extent in the ground building bag 11. In other words, immediately after the ground building material 10 is placed, even if unevenness that is inconvenient for covering with the next ground building material 10 or soil is generated on the upper surface thereof, for example, a ground building immediately after being placed by a flat plate or the like. Material 10
If you hit the top surface of the, the unevenness can be easily eliminated. Of course, even if there is unevenness in the place where the ground building material 10 should be arranged, by doing as described above, the upper surface of the ground building material 10 is flattened regardless of the shape of the lower side thereof. Since it is obtained, the ground building material 10 not only facilitates the stacking work as shown in FIG. 2 but also has a so-called "installation".

After the ground building material 10 has been constructed, for example, the state shown in FIG. 2 is obtained. In this case, a so-called earth pressure is applied to each aggregate 13.
However, as described above, each aggregate 13 has a spherical shape or an oval shape that is extremely strong against the applied force, so that each aggregate 13 is not destroyed by earth pressure.
In particular, after completion of the construction as shown in FIG. 2, since each aggregate 13 has a spherical or oval shape, a force is applied to it not only from above but also from the lateral direction. Each aggregate 13 can withstand this well due to its own shape.

It is important to note that each aggregate 13 has a large number of convex portions 14 or concave portions on the surface thereof, and the surface is uneven, so that the force applied after the construction is applied. Therefore, it does not easily move in the ground construction bag 11. That is, in the ground building bag 11 of the ground building material 10 after the construction, the aggregates 13 are in a state of being engaged with each other by the convex portions 14 or the concave portions thereof, and do not easily move to each other. It has become. This engagement state is the ground construction material 10
Immediately after the disposition, the upper surface of the aggregate 13 can be easily formed by tapping or the like, and the convex portion 14 or the concave portion formed on the surface of each aggregate 13 makes this possible.

Further, in the ground building material 10, if the ground building bag 11 has a large number of small holes 12, as shown in FIG. 3, each aggregate 13 has a spherical or oval shape. Even from the above, the space 15 communicating with the outside through the large number of small holes 12 and sufficient for water to flow between the aggregates 13 is formed in a three-dimensional mesh shape.

The presence of such a space 15 in the earth structure as shown in FIG. 2 means that water is allowed to move through the earth structure, which is natural. It has important meaning in preventing environmental damage. In other words, if the soil structure shown in Fig. 2 is a road that has never existed before and the left side of the figure is a swamp or wetland that moistens the fields or becomes a source of groundwater, it is sufficient before this soil structure is formed. Although groundwater etc. was supplied to the right side in the figure, if this earth structure was constructed using conventional soil or crushed stone, the supply of water would be blocked by this. However, when this earth structure is constructed using the ground building material 10 of the present invention, there is a space 15 for allowing the flow of water in each ground building material 10 as shown in FIG. As mentioned above, the water supply is not interrupted and the nature is protected.

Furthermore, as the ground building material 10,
If a large number of aggregates 13 are housed in a ground building bag 11 that is sealed using a synthetic resin sheet material having no small holes 12, the ground building material 10 can be soft ground, that is, When constructed on a large amount of ground, marshes, wetlands, etc., it is obvious that the amount of sediment in 10 minutes of each construction material can be reduced or reduced, and the soil construction weighs 1/10 or less of the weight of sediment. Even if many materials 10 are piled up,
Since the earth building material 10 in the lower layer and the ground therebelow are not applied with such a large earth pressure / pressure, they do not largely sink. Therefore, if this ground building material 10 is adopted, the earth structure can be built without destroying the groundwater veins due to earth pressure settlement.

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the ground building material 10 according to the present invention will be described with reference to the embodiment shown in the drawings. FIG. 1 is a partially cutaway perspective view of the ground building material 10. Reference numeral 10 is configured by accommodating a large number of aggregates 13 in a ground building bag 11.

The ground-construction bag 11 may be formed as a sheet-like member that is sealed with a material that does not corrode when buried in the soil, for example, a synthetic resin material such as polyethylene, polypropylene, polystyrene, or vinyl chloride. As shown in FIG. 1, it may be formed as having a large number of small holes 12. In order to have these small holes 12, each small hole 12 may be formed by partially punching out a sheet-shaped synthetic resin material, but the ground construction bag 11 is made of a synthetic resin material. It may be formed by forming a net shape. That is, the ground building bag 11 may be a completely closed sheet-like closed bag, or may be a sheet-like or net-like sandbag having a large number of small holes 12. Is.

It is advantageous to form the ground-construction bag 11 from a synthetic resin material. The reason for this is to prevent corrosion even when it is buried in soil as described above, and waste plastic is used as a material. This is because it is possible to process the waste plastic by forming it as. In addition, the ground-construction bag 11 is formed into a literal bag shape in order to prevent scattering of the aggregates 13 housed therein and to secure a certain volume to construct an earth structure. This is so that the required amount of can be easily counted. Furthermore, if the ground building bag 11 is made of a synthetic resin, it is easy to store a large number of aggregates 13 in the ground building bag 11 and then weld the charging port. Material 1
This is advantageous because the production of 0 itself can be facilitated.

The size of the ground building bag 11 is larger than that of the conventional sandbag. Because the completed ground building material 10 can be light in weight as described above, even if the shape of the ground building bag 11 is increased, it does not hinder the transportation or construction. It will not happen. In that sense, the size of the ground building bag 11 is 3 in the vertical direction.
It is possible to have a length of m, a width, that is, a length of about 10 m, or a size of more than that.

Aggregate 13 housed in the ground building bag 11
Is made of a synthetic resin such as polyethylene, polypropylene, polystyrene, vinyl chloride, etc. as a hollow material, and its shape is spherical or oval and the convex portion 14 or the concave portion is formed on the surface. Under the principle of having the above, various modes are conceivable as shown in FIG. 4 or FIG. These Figure 4
Alternatively, the aggregate 13 shown in FIG. 5 has a convex portion 14 formed on the surface thereof. However, by forming a concave portion on the surface of the aggregate, the convex portion 14 is consequently formed, and It may be carried out so as to form irregularities on the surface of.

Various forms of the convex portion 14 formed on the surface of the aggregate 13 are conceivable, and the protrusion 14 may be a simple protrusion as shown in FIG. 4 or shown in FIG. As described above, the protrusion 14 may be formed by forming a recess on the surface of the aggregate 13 as a result. This convex portion 14 restricts the movement of each aggregate 13 when a large amount of aggregate 13 is accommodated in the ground building bag 11 and a certain amount of force is applied, and at the same time, the aggregate 13 It also has a role of reinforcing ribs that enhances the rigidity of itself.

The aggregate 13 as described above has a diameter or maximum length of 2 cm to 2 from the viewpoint of ensuring its rigidity and manufacturing.
It is reasonable in terms of molding work that the length is about 0 cm. Ground construction material 1 using these aggregates 13
To make it 0, the aggregate 13 having the same shape is used as the ground building bag 11
Alternatively, the aggregates 13 of different types may be mixed and stored in the ground construction bag 11 for implementation.

[0026]

As described above, according to the ground building material 10 of the present invention, a large number of spherical or oval bones which are hollow and have a convex portion 14 or a concave portion on the surface are provided in the ground building bag 11. Since the material 13 is housed and configured, waste plastic can be applied as a constituent material, the treatment can be performed at the same time, and the material is lightweight and highly rigid, which is extremely useful as a material for constructing an earth structure. It is possible to provide an excellent ground construction material with a simple configuration.
