DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete retaining wall formed by stacking a number of building blocks for revetment or the like.

[0002]

2. Description of the Related Art Conventionally, in order to prevent the seashore or riverbank from being eroded and deformed by waves or water currents and causing unexpected accidents due to the deformation, the seashore or riverbank must be eroded in advance. It has been practiced to lay a large number of building blocks. Efforts have been made to make the space inside the stacking block close to the natural state by filling it with earth and sand or the like and making it a habitat for living things such as plants and small animals without being left as it is.

[0003] However, since the soil and the like loaded in the internal space of the conventional stacking block are not appropriately supplied with water such as rainwater due to precipitation, the area of the soil and the like in the space inhabits living things such as plants and small animals. It was not the right environment to do. For this reason, a pile block in which organisms such as plants and small animals can hardly inhabit is released from the surrounding natural world and gives an artificial feeling, and it is difficult to achieve harmony with nature.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks and has an excellent function for revetment or for preventing falling of earth and sand from a mountain, and also has a space inside a stacking block. It is an object of the present invention to provide a concrete retaining wall that can achieve harmony with nature by setting the area as an optimal habitat for living things such as plants and small animals.

[0005]

SUMMARY OF THE INVENTION The present invention achieves the above object and has a connecting wall between a front wall and a rear wall having cutouts in the back surface of the upper end and the surface of the lower end. A concrete retaining wall formed by arranging a stack of blocks forming a space communicating vertically and horizontally so as to form a water hole in the vertical direction by the cutouts and filling the space with vegetation soil.

Two side spaces 50, 50 and a center space 60 are formed.

FIG. 3 is a side view of the stacking block 10 shown in FIG. 1, showing a front wall 2 having oblique cutouts 25 and 26.
The connecting walls 40, 40 bridged between the rear wall 30 and the front wall 30
Between the rear walls 20, 30, part of the front and rear walls 20, 30 protrude from the lower ends thereof, and reach the middle of the front and rear walls 20, 30.
The upper space 70 formed above the second and the second 42 communicates with each space (see reference numerals 50 and 60 in FIG. 2).

Here, a method of constructing the concrete retaining wall W shown in FIG. 4 which is a longitudinal sectional view using the concrete building block 10 shown in FIGS. 1 to 3 will be described in detail.

A desired area on the shore or riverbank is defined as a slope A in advance, and foundation concrete C (if necessary, a reinforcing bar may be planted and placed) near a bottom A1 through a foundation material B.
And a backfill material D is laid along the slope A.

Next, the first-stage block row 10A is to be constructed on the foundation concrete C.
While paying attention to the front, many stacking blocks 1
0 is placed on the foundation concrete C in the horizontal direction, and then each space portion of each of the building blocks 10 and 10 (reference numeral 5 in FIGS. 2 and 3)
See 0,60,70. The solidified concrete C1 is added to the solidified concrete (1). After the first-stage block row 10A is constructed on the foundation concrete C in this manner, new pile blocks 10 and 10 are sequentially placed on the pile blocks 10 and 10 which are the forming elements of the first-stage block row 10A. However, the lower end projections 41, 41 of the connecting walls 40, 40 are fitted into the upper ends of the stacking blocks 10, 10, so that the stacked blocks 10, 10 to be mounted are securely positioned. You. And each stacking block 10,
Gravel E as filling material is buried in the side space portion 10 (see reference numerals 50 and 50 in FIG. 2) and the central space portion (see reference numeral 60 in FIG. 2). Stacking block 1
By embedding soil F, which is diversion soil, in the upper space portions of 0 and 10 (see reference numeral 70 in FIG. 3) and leveling,
The second-stage block row 10B is constructed. After the construction of the second-stage block row 10B, the third and subsequent block rows 10B are constructed while adopting the construction procedure of the second-stage block row 10B.
C, 10D, and 10E are constructed, and after the uppermost block row 10E is constructed, a slab (for example, a slab for a vegetation block) is formed so as to cover an upper portion of each of the stacked blocks 10 and 10 in the block row 10E. G is connected, and furthermore, H such as top concrete, earth and sand is laid, and the construction of the retaining wall is completed.

Such a concrete retaining wall has a large number of diagonal water holes 27, formed by diagonal cutouts 25, 26 provided in the front walls 20, 20 of the respective building blocks 10, 10.
27, and plants are planted through the oblique water holes 27, 27. For example, at the time of rainfall, the rainwater
Water flow hole 2 flowing down or directly down the surface of 0, 10
The water is guided to 7, 27, and taken into the soil or the like in the space of each of the building blocks 10, 10 to secure the water necessary for the inhabitation of living things such as plants and small animals. In addition, since the upper end portions 42, 42 of the connecting walls 40, 40 are located in the middle of the front and rear walls 20, 30, it is easy to compact the vegetation soil into the inside thereof, so that the inside of the front and rear walls 20, 30 is easy. Since the walls are laid so that the rear walls are in contact with each other, the function as a concrete retaining wall can be sufficiently exhibited, and the vegetation soil can be held for a long period of time. The vegetation soil may be of any type as long as plants and small animals are bred.
Vegetable soil, palm fiber, etc. can also be used in appropriate combination. In particular, crushed stones, vegetation soil, palm fiber, and the like are suitable for the water colliding section, and soil and the like are preferable for the non-water colliding section. Furthermore, since the water holes 27 are formed in the vertical direction, it is possible to prevent the outflow of vegetation soil, to allow the invasion of plant species and small animals, and to take in rainwater. It is possible to maintain the water content of the vegetation soil to a degree suitable for growing such as. For this reason, the plants grow along the water holes 27, and the plants thrive on the front surface of the concrete retaining wall, so that a landscape close to nature can be maintained, and food for living things such as fish and birds is supplied. And achieve greater harmony with nature.

Although the embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments.
Various changes in design may be made without departing from the spirit of the invention as set forth in the appended claims. For example, although the cross-sectional shape of the notch of the stacking block adopted in the present invention is described as an oblique notch, the water holes formed by the notches can positively introduce rainwater or the like. Therefore, the cross-sectional shape of the notch may be rectangular, curved, or the like. In addition, the target to be input to the pile block is described as gravel, soil, etc., but from the bottom up, the underwater retaining wall, the vegetation retaining wall, and the roadside retaining wall are constructed in the order of the concrete retaining wall on the coast or riverbank. It is good to put crushed stones etc. into the underwater retaining wall part, and to put earth and sand etc. into the roadside retaining wall part, and furthermore, it is stated that there are two connecting walls,
It is not limited to this.

[0016]

As is apparent from the above description, the concrete retaining wall of the present invention not only has an excellent function for revetment or for preventing the fall of mountain soil, but also actively introduces rainwater and the like. By adopting a stacking block with water holes that can be used as an optimal space for living things such as plants and small animals, the interior space of the stacking block makes plants flourish on the outer surface and is close to nature The landscape can be maintained, and food for organisms such as fish and birds can be supplied, thereby enabling further harmony with nature.
