DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments (hereinafter referred to as embodiments) of the invention will be described with reference to the drawings.
[0023]
Drawing 1 is a perspective view of planting block 10 of an embodiment. The planting block 10 includes a plurality of planting blocks stacked or placed horizontally to form a planting block wall. This planting block wall is used for road retaining walls and revetment walls.
[0024]
As shown in FIG. 1, the planting block 10 is roughly divided into a block body 12 and a planting stage group 14 as a planting unit. The block main body 12 includes a front wall 16, a rear wall 18, a pair of vertically standing partition walls 20 and 22 that connect both of them, and a bottom wall 24. Here, in FIG. 1, the thickness of each wall is, for example, 50 mm, the lateral width W is, for example, 1500 mm, the depth width D is, for example, 390 mm, and the height H is, for example, 650 mm. The planting block 10 is made of concrete, for example. The front wall 16 and the rear wall 18 are slightly inclined with respect to the bottom wall 24, and the inclination angle is, for example, 63 degrees. That is, when the side of the planting block 10 is viewed, the planting block 10 has a parallelogram shape. Of course, the form shown in FIG. 1 is an example, and as will be described later, various forms can be adopted as long as rainwater stored therein can be supplied to the plant plant.
[0025]
In the present embodiment, a space surrounded by the front wall 16, the rear wall 18, and the pair of partition walls 20 and 22 is configured as the water storage cavity 100. That is, rainwater or groundwater is taken into the water storage cavity 100 from the outside, and water is stored in the water storage cavity 100.
[0026]
On the other hand, an end space 102 is formed on the side of the partition wall 20 of the block body 12, and an end space 104 is formed on the side of the partition wall 22. In this embodiment, as will be described later, a water channel is formed in the end spaces 102 and 104 for communicating between the water storage cavities 100 of the planting blocks 10.
[0027]
A pair of supply parts 26 for supplying water from the water storage cavity 100 to the planting stage is formed at the lower part of the front wall 16. The water in the water storage cavity 100 can gradually ooze out to the front side through the supply unit 26. Here, the supply part 26 is comprised, for example with ceramics, such as a brick, ie, a porous member, and can adjust supply_amount | feed_rate by adjusting the porosity appropriately. Further, the entire front wall 16 may function as the supply unit 26 made of a porous member such as ceramic. Other members can also be used as long as water can be gradually oozed out. In manufacturing the planting block 10, the water sampling action of the supply unit 26 may be adjusted as appropriate according to the environment in which it is installed, the planting plant, and the like.
[0028]

The water intake 28 is an opening for taking ground water into the water storage cavity 100 from the back side of the planting block 10. A slit 30 is formed on the opening surface as necessary. This is to prevent earth and sand from entering the water storage cavity 100. The slit 30 is preferably composed of a metal flat plate or the like.
[0029]
The planting stage group 14 formed on the front side of the block main body is composed of a plurality of planting stages 32 to 38 as shown in FIG. Although each planting stage 32-38 has the mutually same form, of course, you may make each form different. Moreover, although it is the stage extended in the left-right direction in FIG. 1, of course, a planting part can also be comprised in what is called a pot shape.
[0030]
In the embodiment shown in FIG. 1, stage drainage sections 40 are provided at both ends of each planting stage 32 to 38. Specifically, a stage drainage section 40 made of a porous member is provided at both ends of the stage bottom wall 38A, and the stage drainage section 40 has an action of water oozing out in the same manner as the supply section 26 described above. This allows water to flow sequentially from the upper stage to the lower stage. Incidentally, in each stage, the stage drainage part 40 may be formed only at a predetermined place or one end without providing the stage drainage part 40 at both ends thereof. Further, the stage drainage section 40 is not formed of a porous member, but may be simply an opening as will be described later. In this case, it is desirable to provide a member such as a partition so that soil or the like put in the planting stage does not fall to the lower stage.
[0031]
Each planting stage includes a bottom plate 38A, end plates 38B and 38C, and a front plate 38D. These are integrally formed with the block body 12, but may of course be configured separately from the block body 12.
[0032]
In the planting block 10 configured in this manner, groundwater or the like is taken from the water intake 28 and water is stored in the water storage cavity 100. The water stored in the water storage cavity 100 is oozed out from the supply unit 26 to the front side where the planting stage 38 is provided, and water is supplied to the planting stage, and the upper stage via the stage drainage unit 40 of the planting stage. Water can be supplied from the planting stage to the lower planting stage.
[0033]

As the horizontal pipe 42 and the vertical pipe 44, for example, pipes having a diameter of 50 mm can be used. In addition, the pipe used for the horizontal pipe 42 and the vertical pipe 44 may be comprised by one member, and may be used by connecting two or more members.
[0037]
FIG. 2 is a cross-sectional view of the planting block wall 11 as viewed from the front.
[0038]
As shown in FIG. 2, in this embodiment, openings 46 to 52 are formed at desired positions of the partition walls 20 and 22 and the bottom wall 24, and the end portions of the horizontal pipe 42 and the vertical pipe 44 are respectively inserted. As a result, a horizontal water channel and a vertical water channel are formed. The openings 46 to 52 can be left open, for example, when the planting block 10 is manufactured, or the wall thickness at a desired position is made thinner than other portions, and then the thin portions are punched out. An opening can also be formed. Moreover, at the time of construction in the field of the planting block wall 11, it can also pierce | pierce in a desired position.
[0039]
One end 42A of the horizontal pipe 42 is fitted into an opening 46 formed in the lower part of the partition wall 20, and the other end 42B is an opening 48 of the partition wall 22 of the planting block 10 adjacent in the left-right direction. Is inserted into. The horizontal pipe 42 is disposed in a horizontal state. Thereby, the water storage cavity 100 can be communicated between the planting blocks 10 adjacent in the left-right direction, and the flow of water in the water storage cavity 100 between the adjacent planting blocks 10 can be mutually allowed. As a result, the water stored in the water storage cavity 100 of the planting block 10 can be distributed to the water storage cavities 100 of the planting blocks 10 adjacent in the horizontal direction.
[0040]
As shown in FIG. 1, the vertical pipe 44 has an inverted L-shape. One end 44 </ b> A of the vertical pipe 44 is inserted into an opening 50 formed in the upper part of the partition wall 20, and the other end 44 </ b> B is inserted into an opening 52 formed in the bottom wall 24. . As shown in FIG. 2, the bottom wall 24 forms a top plate of the lower planting block 10. Therefore, by forming the openings 50 and 52 in the partition wall 20 and the bottom wall 24 and connecting them with the vertical pipes 44, the upper and lower planting blocks 10 of the upper storage block 100 of the upper planting block 10 are connected. The water storage cavity 100 can be communicated with each other. Thereby, the water storage of the water storage cavity 100 of the upper planting block 10 can be distributed to the water storage cavity 100 of the lower planting block 10. As a result, water can be replenished from the ten water storage cavities 100 of the upper planting block to the water storage cavities 100 of the lower planting block 10.
[0041]
The opening 50 at the top of the partition wall 20 of the vertical pipe 44 can be provided at a desired position. By adjusting the position where the opening 50 is formed, the water level of the water storage cavity 100 can be adjusted. As shown in FIG. 2, in this embodiment, the opening part 50 is formed so that the height h between the bottom face 28a of the water intake port 28 and the bottom face 44c of the vertical pipe may be 2 to 3 mm. As described above, by forming the opening 50 at a relatively high position from the bottom surface of the water storage cavity 100, sufficient water storage can be performed in the water storage cavity 100.
[0042]
As shown in FIG. 2, the planting block wall 11 connects the end spaces 102 and 104 of the adjacent planting blocks 10, thereby forming a connection space, and the horizontal pipe 42 is formed in this connection space. The vertical pipe 44 is formed in one of the end spaces 102 and 104. The upper and lower planting blocks 10 can be connected to each other by, for example, connecting the bottom wall 24 of the upper planting block and the upper parts of the partition walls 20 and 22 with bolts and fastening them firmly.
[0043]
The connecting space in which the end spaces 102 and 104 of the planting block 10 are connected is filled with a trunking material 106 made of, for example, a concrete material. The body member 106 is inserted, for example, to increase the weight of the planting block wall 11, but when the water paths of the horizontal pipe 42 and the vertical pipe 44 are formed in the end spaces 102 and 104, the opening material 106 is opened. The advantage of sealing the gap between the portions 46 to 52 and the ends of the horizontal pipe 42 and the vertical pipe 44 can be obtained. Therefore, it is not necessary to construct a special sealing structure for forming a water channel.
[0044]
Furthermore, in this embodiment, the horizontal pipe 42 connects all the water storage cavities 100 of the planting blocks 10 adjacent in the left-right direction, and the vertical pipe 44 is horizontal as shown in the middle and lower stages of FIG. At least one or more are provided for each stage of the planting blocks 10 connected in the direction. As a result, in this embodiment, the water storage of the water storage cavity 100 of the planting block 10 which comprises the planting block wall 11 can be equalized. For example, the vertical pipe 44 may be provided with two or more vertical pipes as shown in the lower part of FIG. 2 in consideration of a case where a certain vertical pipe stops functioning for some reason.
[0045]
Moreover, in this embodiment, since the water storage of the water storage cavity 100 is equalized by the whole planting block wall 11, the water intake 28 for taking in water to the water storage cavity 100 of the planting block 10 is a part of planting. It may be provided only on the tree block 10.
[0046]
In addition, as shown in FIG. 2, even if it does not form the horizontal pipe 42 and the vertical pipe 44 so that the water storage of the water storage cavity 100 of the planting block 10 which comprises the planting block wall 11 may equalize, for example, planting Only the planting block 10 having poor water storage efficiency in the block wall 11 may be communicated with the water storage cavity 100 of another adjacent planting block 10.
