Abstract

PROBLEM TO BE SOLVED: To reduce the construction period, significantly increase the economical efficiency, and prevent the outflow of topsoil even at the time of considerable rainfall. SOLUTION: After a tire block 2 formed by filling concrete in a waste tire have been laid on the face of slope or the like, a vegetation bag 1 filled with vegetation base materials such as soil, or curing agents such as various fertilizers is housed in the central hole 2a of the tire block 2. Further, the vegetation bag 1 is formed in a circular shape so as to be situated along the inner circumferential surface of the central hole 2a of the tire block 2 in such a state that plantation base materials or a curing agent 3 (not shown) are filled.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for greening a slope or the like using waste tires containing concrete and a vegetation bag used for the method.

[0002]

2. Description of the Related Art Conventional greening methods such as slopes include:
Work to apply vegetation soil to cast-in-place concrete lattice frames, that is, install concrete concrete frames in each rectangular frame of cross-shaped reinforcing bars arranged vertically and horizontally with respect to the slope and put concrete between each formwork The mainstream method was to throw vegetation into a concrete frame provided by spraying to achieve vegetation. However, the work of manufacturing this concrete lattice frame is large, requires a long construction period, and increases costs.

Therefore, a construction has been developed in which a rectangular frame-shaped concrete block is formed in advance, and the concrete block is laid on a slope to apply soil. As one of them, a method of performing greening work using a concrete block using waste tires has been proposed (for example, Japanese Patent Laid-Open No. 6-257).
172). In this method, in a retaining wall or retaining work performed for stabilization of slopes and prevention of collapse by embankment or embankment, a tire block filled with concrete in the cavity of a waste tire is formed into a rectangular frame as described above. In place of the concrete block, laying is done, and the soil is applied to the central hole to plant vegetation. By this method, the production cost of the concrete block can be reduced, and in addition, it can be implemented as a part of a waste disposal measure for waste tires.

[0004]

However, it is still inefficient to put the soil on a slope with a poor scaffolding, etc., and depending on the quality of the soil, when the rainfall is considerable, it may be difficult to install the soil. Water often stays inside and the soil becomes fluid and often flows over the frame.

[0005]

Therefore, in the present invention, a tire block formed by filling concrete into a waste tire is laid on a slope or the like, and a vegetation base such as soil is placed in a central hole of the tire block. A vegetation bag filled with a curing material such as timber or various fertilizers is accommodated.

The vegetation bag used in the greening work of the present invention is filled with a vegetation base such as soil or a curing material such as various fertilizers in a circular shape along the inner peripheral surface of the center hole of the tire block. It is formed so that it can be accommodated in the central hole of the tire block without any gap.

[0007] The seeds of the plant may be included in the vegetation base material mixed with the soil and various fertilizers, water retention agents, and the like to be filled in the vegetation bag. To form a vegetation base layer in advance, and then spray only seeds on the surface layer later,
Ivy and shrubs may be planted.

Embodiments of the present invention will be described below with reference to embodiments shown in the drawings. FIG. 1 is a front view showing a vegetation bag according to the present invention, FIG. 2 is a perspective view showing a vegetation bag and a tire block, FIG. 3 is a cross-sectional view showing a state where a vegetation bag is accommodated in a tire block, and FIG. It is a perspective view of the slope which performed the greening method.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a vegetation bag 1 used in the greening method of the present invention will be described. The material of the vegetation bag 1 is a cloth having a coarse mesh spun with natural fibers such as hemp, nylon, polyester or the like or chemical fibers. As shown in FIG. 1, a part of the uppermost end is opened, and all the edges are sewn to form a circular bag. This vegetation bag 1
After the inside is filled with a vegetation base material or a curing material 3 described later, the upper opening 1a can be closed with a squeezing cord 1b.

In FIG. 2, reference numeral 2 denotes a tire block formed by filling a waste tire with concrete, and concrete is cast except for a central hole 2a. Here, the vegetation bag 1 is formed in a circular shape along the inner peripheral surface of the central hole 2a of the tire block 2 in a state where the vegetation bag 1 is filled with a vegetation base material such as soil or a curing material 3 such as various fertilizers. Accordingly, the center hole 2a can be quickly accommodated without any gap.

Next, a vegetation base material such as soil or a curing material 3 such as various fertilizers to be filled in the vegetation bag 1 will be described.
For example, as the soil, red ash soil (a type of volcanic ash soil),
As a fertilizer, a slow-acting fertilizer, a warm-acting fertilizer or a fast-acting fertilizer is used, and as a water retention material, vermiculite, perlite or an organic fiber material (for example, bark compost) is used. In addition, lime, phosphoric acid, slaked lime, calcium silicate, etc. can be used as clay minerals, soil conditioners and pH adjusters,
One or two or more of these are appropriately combined and filled.

Next, the construction method of the present invention will be described. For example, as shown in FIG. 4, first, a tire block 2 is developed and laid on the entire slope. Then, concrete or mortar flows between the adjacent tire blocks 2 and solidifies to form the retaining wall surface 4.
The vegetation bag 1 previously filled with the above-mentioned vegetation base material or curing material 3 is accommodated in the central hole 2a.

The vegetation bag 1 laid as described above contains sufficient nutrients necessary for the growth of plants, and the moisture necessary for germination, vigor and growth is effectively secured by a water retention agent or the like, and the development of rhizomes is ensured. A sufficient layer thickness can be secured for the essential soil thickness. Also, the vegetation base material 3 and the like that have been filled are protected by the vegetation bag 1 and do not flow away even in a strong wind or rainfall.

[0014]

The present invention is configured as described above.
It has the following excellent effects. (1). Since the vegetation bag is formed in a circular shape along the inner peripheral surface of the center hole of the tire block, it is possible to quickly apply the soil to the tire block without any gap. (2). There is no need to put in the soil on slopes with poor scaffolding, etc., and it is easy to handle when raising and arranging on slopes, not only can prevent the risk of falling etc., but also shorten the construction period. Significantly increase economic efficiency. (3). The vegetation base material and the like are protected by the vegetation bag even during a considerable rainfall, and can be prevented from being washed away.
