Description

  The present invention relates to a slope protection method for preventing soil erosion and weed growth and improving safety and design, and is a slope protection method useful on a playground slope.

  As a conventional banking slope protection method, for example, a soil drainage prevention method due to rainfall, a protection method using concrete, a protection method using a prototype waste tire, or the like is known.

  However, when concrete is used for protection of embankment slopes, there is a problem that it gives a cold appearance, and when an adult or a child walks down on the slope, the impact is great and leads to a fracture accident or the like.

  On the other hand, when the prototype waste tire is used to protect the embankment slope, it is necessary to fill the cavity of the tire with a filler such as soil without any gaps in order to achieve a stable protective structure. It was. Also, large tires such as truck and bus tires have drawbacks in handling and weight, and in some cases, are extremely difficult to handle. In addition, it is good to protect the slope by stacking the original waste tires while shifting little by little horizontally, but when the original waste tires are placed upright and installed, the filler on the upper part of the tire falls etc. There was a problem of lack of workability.

  Furthermore, as a slope protection method using waste tires, Patent Document 1 provides a recycled tire slope frame structure that is flexible, robust, and highly stable without using special tools or heavy machinery. It is reported. Further, Patent Document 2 proposes a frame work that can be constructed at a low cost and has durability as a method for protecting a slope using a waste tire, and a construction method thereof.

The recycled tire slope frame structure disclosed in Patent Document 1 connects a plurality of half-recycled tires to each other and to each other, and the inner peripheral edge of the wheel portion is fixed to the slope with an anchor reinforcing bar. And it fixes to the direction as a whole as a whole. In addition, the frame work and the construction method disclosed in Patent Document 2 are sequentially spread and arranged on the slope, and a frame made of a plurality of waste tires connected to each other, and the frame of the frame It is a frame work in which the slope is covered with adjacent filling tires and filling materials filled in the inside of the tire.

  However, the construction method that has been known as a slope protection method using waste tires can sufficiently prevent soil erosion and weed growth, and can also satisfy workability, safety, and design. Not necessarily a thing.

  For example, the construction method disclosed in Patent Document 1 requires a fastener for connecting a plurality of half-recycled tires, an anchor reinforcing bar for fixing the inner peripheral edge of the wheel portion to the slope, and the construction work increases. At the same time, there is a problem that the cost is increased due to the fixing member. Moreover, in the construction method described in Patent Document 2, when filling a hollow portion of a waste tire laid horizontally with a filler such as soil without a gap, a lot of filling material is required, and it takes time and effort. There was a problem in work efficiency.

  Therefore, the object of the present invention is to solve the above-mentioned problems, facilitate construction on slopes and connection between waste tires, prevent soil erosion and weed growth, and also provide safety and design. It is to provide an excellent slope protection method.

  In order to solve the above-mentioned problem, the slope protection method of the present invention is characterized in that a cut piece of a waste tire divided in a radial direction is applied to an inclined slope such as embankment so that the cavity is inside. It is what.

  In the direction protection method of this invention, it is preferable that the said cut piece is formed by dividing a waste tire into 2 parts, 3 parts, 4 parts, or 5 parts in the radial direction. Further, it is preferable to fill a ground material inside the cavity of the cut piece, and further, the cut piece is applied from the lowest stage to the upper stage sequentially, and the cut pieces adjacent to each other in the vertical direction are applied to each other. preferable. Furthermore, the cut piece can be suitably fixed to the inclined slope with an anchor bolt, and two cut pieces may be connected and fixed with one anchor bolt. Furthermore, a sealing material may be placed between the cut pieces.

  According to the slope protection method of the present invention, the construction on the slope and the connection of waste tires can be facilitated, soil erosion and weed growth can be prevented, and the method is excellent in safety and design. A surface protection method can be provided. It is also excellent in terms of environmental conservation due to the effective use of waste tires.

Embodiments of the present invention will be described below with reference to the drawings.
In the slope protection method shown in FIG. 1, the cut piece 1 of the waste tire divided | segmented into radial direction is put on the slope slope 10 such as embankment so that a cavity may become inside. In carrying out this slope protection method, first, a cut piece 1 having a sector shape is obtained by dividing a waste tire in a radial direction. Next, the surface of the inclined slope 10 that needs to be protected is adjusted to an uneven state so that the tire piece can be easily constructed. After that, the cut piece 1 is placed on an inclined slope 10 such as embankment so that the cavity is on the inside, thereby obtaining the protection slope shown in the figure.

  As shown in FIG. 4, this cut piece 1 is formed by dividing the waste tire A into two parts (a), three parts (b), four parts (c) or five parts (d) in the radial direction. Is preferred. For such division, the number of divisions may be appropriately selected depending on the inclination angle of the slope, and for example, when the inclination angle is about 45 degrees, the waste tire A is particularly preferably divided into four divisions.

  The slope protection method is preferably constructed by filling the ground material 2 in the cut piece 1 and covering the sloped slope surface 10 with regularity so that the cavity is inside, as shown in FIG. Thus, it is preferable to construct the cut pieces 1 sequentially from the lowermost stage toward the upper stage, and abut the cut pieces adjacent to each other vertically. At this time, by using waste tires having a uniform size, it is possible to obtain a sloped protective appearance that is excellent not only in safety but also in design.

  In order to enhance the safety of slope protection, it is preferable to fix the cut piece 1 to the slope slope 10 with the anchor bolt 3. The anchor bolt 3 is driven from the surface portion of the cut piece 1 and is integrally fixed to the inclined slope 10. At this time, as shown in FIG. 2, the anchoring angle of the anchor bolt 3 is preferably about 45 degrees with respect to the horizontal.

  Further, two cut pieces 1 may be connected and fixed by one anchor bolt 3. In this case, as shown in FIG. 3, the bottom of the upper cut piece 1 is placed on the uppermost end of the lower cut piece 1, and the anchor bolt 3 is driven in the overlapping portion. Two cut pieces 1 can be fixed integrally. As shown in the drawing, by connecting the two cut pieces 1 of the lower stage and the upper stage with anchor bolts 3, the strength to the inclined slope 10 can be increased. In addition, the butt | matching and connection method of cut pieces are not specifically limited.

  Furthermore, although not shown, the sealing material 4 may be placed between the adjacent cut pieces 1. By placing the sealing material 4 on the portion where the cut surfaces of the cut pieces 1 are in contact with each other, the internal penetration of moisture can be reduced and the overall strength can be further increased.

  According to the present invention, it is possible to protect sloped soil such as embankment and prevent outflow due to heavy rain or soil erosion, so that the present invention can be suitably applied to hill-shaped playgrounds. In this case, even if the child falls on the slope, it is safer than concrete. Moreover, weed growth prevention, excellent weather resistance, and the like on such a slope can be obtained. Furthermore, the cut piece of the waste tire that has finished its role has room for utilization such as reuse for civil engineering purposes or heat utilization.
