Description of the Related Art In a construction using a box-shaped block or an H-type or I-type product block (hereinafter abbreviated as a block), a hole is conventionally drilled in the back surface of the block in order to provide a drainage function to the back surface. There have been taken measures such as using a structure, opening the back of the block and applying a porous net to that portion, or interposing crushed stone between the block and the slope. For sucking out the earth and sand from the opening, a suction preventing material having a mesh structure has been used. Furthermore, in the case of a box-shaped block intended for planting, the back of the block had to be opened or a perforated structure had to be used in order for roots to reach the back slope. .

In addition, when a hole is drilled for the purpose of plant rooting, there is a runoff of earth and sand from that part, and the need for runoff prevention materials arises,
It is a difficult point during construction. Therefore, a multifunctional block that does not require the use of another material such as a suction-preventing material on the back and a greening method using the same were studied.

Opening on back side of precast concrete block
We have developed a porous block on the back side that has a porous part outside and a function to prevent water penetration, roots, and suction of earth and sand. The porous material as used herein refers to a material that can be integrated with the cement of the block skeleton during the production or use of a precast concrete product, and can maintain that state semipermanently. Any inorganic or organic material can be used as long as continuous pores can be maintained inside and outside to allow water passage and rooting. The back side includes not only the normal back but also all sides facing the slope except the front side of the block.

マット等を用いることができる。The most preferable porous material is an inorganic porous concrete, and it is preferable that the porous material is integrally formed on the back side of the box-shaped block at the time of forming. In addition to the rectangular shape, the box shape includes a shape in which the back side is narrowed according to required specifications, and a shape having a constricted portion in an intermediate portion. Since these box-shaped blocks have a porous material between the inner space and the back portion, they have multi-functions such as water passage, passage, and prevention of suction. As the organic porous material, a synthetic resin having continuous ventilation holes, natural fibers such as coconut fibers, or a synthetic resin fiber mat can be used.

Since these stacked blocks also have a porous material between the stuffing space and the back, they have multiple functions of water passage, rooting, and suction prevention.

The retaining wall may be formed to be slightly inclined, curved, or uneven in the vertical direction other than the vertical one. The water supply means referred to herein includes at least a pipe for supplying water into individual blocks such as a retaining wall formed by stacking back porous blocks and a means for connecting to a water storage facility or a water supply. It also includes providing a timer, a sensor, a pump, and the like so as to supply water periodically or automatically at the time of drying as needed.

In the example shown in FIG. 1, an opening 5 is provided on a back plate 4 of a box-shaped block without a bottom plate by a front plate 2, both side plates 3, 3 and a back plate 4, and a porous concrete layer is formed as a porous material 6. It is provided integrally. Water and plant roots can enter and exit through the opening 5. The opening 5 is not limited to a rectangular hole, and may be circular, or may be cut out from above or below for convenience of molding. The molding may be performed simultaneously or integrally, or the rectangular frame and the porous concrete plate may be formed separately, and then bonded and integrated to form a product. The example of FIG. 2 is an example in which the back plate 4 is formed by the porous material 6. In the block forming, the inside of the mold has the front plate 2 and the both side plates 3, 3, and a normal block composition mixture. Four parts were filled with a known porous concrete composition and molded. In the previous examples, the side plates 3, 3 were longer box-shaped blocks than the front plate 2, back plate 4, but as shown in FIGS. Blocks can be implemented similarly. Figures 3 and 4
In the above example, when concrete is poured into the inside, the conventional block front plate can be used as a discarded mold block in which the retaining wall exposed surface is formed.

It is an Example sectional view of a greening method. When constructing a retaining wall using any of the above-mentioned back porous blocks 1, a water supply means 10 is provided to the outer surface side (FIG. 6) or the inner surface side (FIG. 7) of the back porous material . I have. A perforated water supply pipe 11 is piped downward from the top slope of the back of the retaining wall, and the water storage tank at the top
Supply water from 12. Figure 6 provided on the outer surface of the block
Is preferable to FIG. 7 on the inner surface side. That is, the water supplied from the porous water supply pipe 11 passes through the porous material 6 of the rear porous block of the present invention constituting the retaining wall in the example provided on the outer surface side in FIG. Supply water to On the other hand, excess water in the block escapes downward through the porous material 6 and is always maintained in the best condition for the growth of the plant, and root rot does not occur. As the roots elongate, they pass through the porous material 6 and become rooted in the direction of the slope 13 to promote the growth of the plant and to obtain the reinforcing effect of the retaining wall. The water supply by the water supply pipe is preferably a siphon type natural fall,
Forcible supply by a pump or the like is also possible.
