As a result, rainwater or the like smoothly flows downward from above in the soil in the stacked vegetation blocks, and rainwater or the like does not stay in the soil.

At this time, the soil contains air, but such air also flows downward following the flow of the rainwater or the like, and the air staying in the soil is discharged to the outside. As it is discharged, fresh air is taken in and the soil is activated.

Therefore, sufficient moisture, nutrients and fresh air can be given to the soil of each of the stacked vegetation blocks to improve the growth environment of the plants vegetated on the soil. it can.

In addition, when the lumps are stored in the water collection / water supply chamber, the small animals can function not only as the water collection / water supply function described above but also as a habitat for small animals. It is possible to freely move between the room and the water collection / water supply room, providing a comfortable living / habiting space for small animals.

The above-mentioned vegetation blocks are stacked in an upward direction, and rainwater flowing down through the guest soil chamber of the vegetation blocks arranged in the upper stage flows into the water collection / water supply chamber of the vegetation blocks arranged in the lower stage. It is arranged to.

In this way, rainwater flowing down in the soil filled in the soil of the vegetation block can be collected in the water collection / water supply chamber of the vegetation block arranged in the lower stage. Rainwater flowing on the upper surface of the soil can be collected in the water collection / water supply room located behind the soil.
It is possible to continuously supply water to the soil filled in the soil of each block from the water collection and water supply room.

Therefore, rainwater or the like that has fallen on the soil of each block can be effectively utilized as a supply of water and nutrients to small animals such as plants and bacteria planted on each soil. .

[0126] Here, the soil receiving wall 42 is formed in the front of the soil receiving chamber 22 and the backfill material U formed behind the soil receiving wall 42.
Since it is partitioned from the space that is filled with, etc., it is possible to secure a large soil space 22 for the soil, and even if the soil G in the soil chamber 22 is scoured, it will be backfilled. The material U and the like can be prevented from flowing into the guest soil chamber 22 and the guest soil chamber 22 can be satisfactorily secured.

Further, the disposition position of the soil receiving wall 42 is not limited to the position just below the front end of the water collecting / water supplying body 2, but may be appropriately displaced to the natural ground D side to dispose the soil receiving chamber 42. 22 can be set to a large value.

FIG. 24 and FIG. 25 show a slope protection block A as a fourth embodiment. In the slope protection block A, the water collecting / water supply body 2 is placed in the upper half of the block body 1. The front-rear partition wall 50 for partitioning the part in the front-rear direction and the up-down partition wall 51 for partitioning the middle part of the block body 1 in the up-down direction
In the lower part of the front-rear partition wall 50, a rainwater outflow passage 14 is formed in the lower part of the partition wall 50 for letting out rainwater and the like flowing into the water collecting / supplying body 2 into the front soil chamber 22. .

The upper surface 51a of the vertical partition wall 51
Is designed to have a front low front high slope, so that rainwater or the like can be smoothly guided to the rainwater outflow passage 14 side.

In this manner, the left and right side portions of the water collecting / watering body 2 are fitted / placed in the fitting / mounting recesses 52, 52 of the left and right side wall bodies 4b, 5b, and are mounted in a horizontal shape. be able to.

24 and 26 show a modification of the slope protection block A as the fourth embodiment, in which the front-rear partition wall 50 and the up-down partition wall 51 are formed as separate bodies. A slit-shaped rainwater outflow passage 14 is formed between the lower end surface of the direction partition wall 50 and the upper surface of the vertical partition wall 51. 53 is a fixed bracket.

27 to 32 show a slope protection block A for land, which has the same basic structure as the above-mentioned slope protection block A for rivers, but for connection / fitting. The front ends of the concave / convex ridges 8 and 7 are arranged so as to coincide with the upper ends of the front wall 3, and the upper portions of the rear side of the concave / convex ridges 8 and 7 for connection / fitting are partially cut away to form the block body 1 An opening 54 is formed on the upper front side of the above so as to open largely to the left and right.

Therefore, in the slope protection block A, the connection / fitting concave / convex ridges 8 and 7 are located in front of the slope protection block A for rivers, and these are inclined forward. Although the front wall 3 is in a state of being bulged forward from the left and right sides of the front wall 3, it is not necessary to consider the resistance of the flow of the river K, etc., so that the connection / fitting position is arranged on the front end side as much as possible. Then, the slope protection block A can be easily rotated around the axis in the substantially vertical direction.
I am able to adjust it.

33 to 40 show a slope protection block A as a fifth embodiment. The slope protection block A has a basic structure for slope protection as the first embodiment. Same as the block A, but the entrance / exit passage forming plate 43 is integrally formed in a horizontal shape between the front portions of the left and right side walls 4 and 5 of the block body 1, and the entrance / exit passage forming plate 43 is used to collect water in the lower stage.・ Water supply 2
By arranging it on the rainwater etc. inflow path 13 formed above, the area immediately above the rainwater etc. inflow path 13 is covered and the rainwater etc. inflow path 13 is covered.
Is prevented from being blocked by the backfill material U and the like, so that small animals can always reliably go in and out of the water collection / water supply body 2 through the rainwater inflow passage 13.

Moreover, the capillarity-generating material M is inserted into each rainwater outflow passage 14, and the rainwater and the like in the water collection / water supply chamber 49 is passed through the capillarity-generating material M by means of the capillarity to obtain a soil chamber 22 which will be described later. It is possible to supply to.

Here, as the capillarity causing material M, a fiber string which can be inserted into the rainwater outflow passage 14 can be used.

Further, in the water collecting / water supplying body 2, the front end edge portion of the bottom portion 17 is extended forward of the front wall 12 so that the rainwater guide portion 17a is provided.
Is formed.

In this way, the rainwater or the like flowing into the soil chamber 22 from the water collecting / water supply body 2 through the rainwater outflow passage 13 is
The rainwater guide portion 17a is guided to the side closer to the center of the guest soil chamber 22 as much as possible.

At the upper part of the rear half of the left and right side walls 20, 20 of the water collecting / watering body 2, overflow recesses 44, 44 are formed in a stepped recess, and the rear ends of the overflow recesses 44, 44 are rearward. The same position as the upper surface of the wall 18 is set, and the upper surface of the rear wall 18 serves as a recess 45 for inflowing groundwater or the like.

As described above, the slope protection block A is
Between the right and left side wall bodies 4b and 5b of the block body 1, the soil receiving wall 42 is laid horizontally via the wall mounting grooves 4d and 5d.
The water collecting / water supplying body 2 is laid horizontally on the b and 5b, and subsequently, a lateral partition wall 9 is fitted between the front wall 3 of the block body 1 and the front wall 12 of the water collecting / water supplying body 2. It can be assembled by crossing over via 15,16.

At this time, since the front wall 3 is inclined forward, the vegetation area on the upper surface of the soil S can be formed as large as possible. The front wall 3 of the slope protection block A arranged at can be covered.

In particular, even if the slope to be protected has a steep slope, a wide vegetation area can be secured.

When the retaining wall is constructed along the slope of the river K, since the front wall 3 is in the forward leaning posture,
The front wall 3 of the slope protection block A arranged in the upper stage covers the upper part of the soil S of the slope protection block A disposed therebelow, and the soil G is scoured by the flow of the river. Can be reduced.

The rainwater and the like that have flowed into the water collection / water supply chamber 49 can be made to flow out into the guest soil chamber 22.
It is possible to supply water and nutrients to small animals such as plants and bacteria vegetated on the soil G in 22.

Moreover, in the rectangular frame-shaped block body 1,
By filling the backfill material U between the block body 1 and the ground D, the soil G and the ground D filled in the soil chamber 22 can be brought into a continuous state. The effect of the outside temperature of G can be reduced, and small animals such as plants and bacteria vegetated in the soil G can be replenished with water and nutrients from the ground D.

Further, the air flow between the soil G and the ground D can be made more active to activate the soil G and the ground D. From this point as well, the environment for growing living things can be improved. It can be secured well.

Therefore, despite the provision of the slope protection block A, it is possible to grow the organism in its natural state without disturbing the natural ecosystem, and to protect the organism. The labor and cost for management can be eliminated.

Further, since the water collecting / water supplying body 2 functions not only as a water collecting function but also as a living space for living things, small animals can freely move between the guest soil room 22 and the water supply room 11. It is possible to provide living spaces and living spaces that are comfortable for living things.

Therefore, the growth of small animals can be protected and the growth environment of the vegetated plant F can be improved.

In addition, the groundwater containing nutrients discharged from the natural ground D can be guided to the water collection / water supply chamber 49 → the soil soil chamber 22 and the soil soil G filled in the soil soil chamber 22 can be guided. Can be fed to.

Further, when rainwater or the like pouring on the surface of the soil G filled in the soil chamber 22 flows into the water supply chamber 11, the rainwater or the like is passed through the rainwater inflow passage 13 to the soil chamber. It is possible to guide to the soil G within the area 22, and it is possible to secure good humidity in the soil G.

The air between the soil G and the ground D filled in the soil chamber 22 vigorously flows to activate both the ground G and the ground D.

In addition, small animals move over the soil G filled in the soil chamber 22, and by excrement or leaving dead bodies on the soil G, it becomes a nutrient of the soil G. As a result, it is possible to improve the growth environment of the vegetated plant F.

Therefore, from these points as well, it is possible to ensure a favorable growth environment for the vegetated plant F.

Further, by arranging and partitioning the inside of the soil chamber 22 by the left-right partition wall 9 in a direction substantially orthogonal to the flow direction of the river K, even when the water level of the river K rises during a flood or the like. The amount by which the soil G filled in the soil chamber 22 is scoured by the running water of the river K can be suppressed by the left-right partition wall 9 so that the soil G is washed away as much as possible. The vegetation function of the block body 1 and the function of protecting / managing organisms can be well secured.

FIG. 41 is a schematic diagram of the flow of rainwater and the like on the seawall retaining wall Y shown in FIG. 33. The rainwater and the like that have flowed into the water supply chamber 11 of the uppermost slope protection block A cause capillary action. By the capillary phenomenon through the material M, it is supplied into the guest soil chamber 22 and flows into the water collection / water supply chamber 49 of the separate slope protection block A immediately below the guest soil chamber 22 and similarly. Soil chamber 22 → water collection / water supply chamber 49 → guest soil chamber 22 → …… While repeating, it flows down sequentially, but rainwater etc. always flows into the soil chamber 22
Water and nutrients can be supplied to the small plants such as the plant F and the bacteria that are planted in

Here, into the water collection / water supply chamber 49, rainwater, groundwater, etc. also flow in from the rainwater, etc. inflow passage 13 and the groundwater, etc. inflow recesses 19, and these are also always in the guest soil chamber. It is continuously supplied to 22 through the capillary action-generating material M in small amounts.

42 and 43 show a modification of the slope protection block A as the fifth embodiment described above, in which a bottom portion 60 is formed in the block body 1 and the front portion of the bottom portion 60 extends in the left-right direction.
