However, the means described in Patent Document 1 has a problem that construction is troublesome because of its large structure, and plants are easily withered due to drying or the like, and greening is not performed smoothly.
Moreover, since the means described in Patent Document 2 uses a sheet that is a soft material, the plant does not grow smoothly and the greening is not sufficiently promoted because the plant line hurts or the drainage is poor. There is a problem.

  Accordingly, an object of the present invention is to provide a greening structure and a greening structure composite that prevent outflow of earth and sand, have a simple configuration, are easy to construct, and can be effectively planted. There is.

In order to achieve the above-mentioned object, the greening structure (1) according to claim 1 of the present invention is installed on the ground (E) such as a slope or a road separation zone to prevent outflow of earth and sand. However, for greening,
At the time of installation, the cylinder wall part (13) is erected from the upper end opening part (12) which is formed at the upper end part of the cylinder main body part (11) having a substantially truncated cone cylinder shape or a substantially truncated pyramid cylinder shape. An inner cylinder (10) made of resin that fills the inside with culture soil (S) and buryes the lower end in the soil;
An intermediate made of a water-permeable material that is fitted so as to cover the outside of the inner cylinder (10) and has an insertion hole (21) through which the cylinder wall (13) of the inner cylinder (10) is inserted at the upper end. Body (20);
The inner body is fitted so as to cover the outer side of the intermediate body (20) and is inserted into the upper end portion through the insertion hole (21) of the intermediate body (20). The cylindrical wall portion (13) of the cylindrical body (10) further has a hole (31) through which it is inserted, and the lower end portion is made of resin and has a mesh shape with a flange portion (32) grounded to the ground (E). The outer cylinder (30). In addition, it means that the natural soil of the ground (E) is also contained in culture soil (S).

  Further, the greening structure (1) according to claim 2 attaches and detaches the cylindrical wall portion (13) of the inner cylindrical body (10) and the upper end portion of the outer cylindrical body (30) by an engagement mechanism. Characterized by free assembly

  The greening structure (1) according to claim 3 is characterized in that the intermediate (20) is formed by compressing a wood chip.

  Furthermore, the structure for greening (1) according to claim 4 is characterized in that the intermediate body (20) is made of water-permeable lightweight concrete.

The structure composite for greening (2) according to claim 5 is installed on the ground (E) such as a slope or a road separation zone, and is used for greening while preventing the outflow of earth and sand. And
A plurality of greening structures (1) according to any one of claims 1 to 4 are integrally assembled in a planar shape.

  Symbols in parentheses indicate corresponding elements or corresponding matters described in the drawings and the best mode for carrying out the invention described later.

According to the structure for greening according to claim 1 of the present invention, a resin-made inner cylinder having a substantially truncated cone cylinder shape or a substantially truncated pyramid cylinder shape, an intermediate body made of a water-permeable material, and a substantially pyramid cylinder shape Or since it is provided with the resin outer cylinder body in the shape of a substantially truncated cone, the configuration is simple and lightweight.
Therefore, handling is easy and construction becomes very easy.

  Moreover, since the lower end part of the inner cylinder is buried in the soil, the buried lower end part functions as a weir, and the outflow of earth and sand can be prevented.

Furthermore, since the plant extended from an upper-end opening part is promoted for the following reasons, it can promote greening effectively.
(1) Since the plant line is reliably protected by the three members of the inner cylinder, the intermediate body, and the outer cylinder, there is no pain.
(2) Since only the lower end portion of the inner cylinder is buried in the soil, its upper portion protrudes from the ground. Therefore, it is well drained and prevents plant root rot. Further, when a plurality of greening structures are installed side by side, a groove is formed between them, and drainage is improved by the groove, so that root rot can also be prevented.
(3) Drying of the ground is effectively prevented by the three members of the inner cylinder, the intermediate body, and the outer cylinder. In particular, since the intermediate body is made of a water-permeable material, the water that has passed through the mesh-like outer cylinder body is allowed to flow appropriately while retaining water, thereby preventing plant line and root drying.
(4) The plant is effectively kept warm in winter by the three members of the inner cylinder, the intermediate body, and the outer cylinder.
(5) The three members on the inner cylindrical body, the intermediate body, and the outer cylindrical body reliably block sunlight and effectively prevent weeds from growing on the ground.
(6) Prevents rebound of earth and sand due to rain, so the lower leaves of plants do not hurt.

Furthermore, since the inner cylinder has a substantially truncated cone cylinder shape or a substantially truncated pyramid cylinder shape and its peripheral wall is inclined in a mountain shape, the posture after the arrangement can be stably maintained over a long period of time. Moreover, since the culture soil with which it is filled also has a mountain shape, it is difficult to collapse and a stable posture can be maintained.
Moreover, since the outer cylinder is also made into the substantially pyramid cylinder shape or the substantially truncated cone cylinder shape, the attitude | position after installation can be stabilized.

Further, according to the greening structure of the second aspect, in addition to the function and effect of the invention of the first aspect, the cylindrical wall portion of the inner cylindrical body and the upper end portion of the outer cylindrical body are connected to the engagement mechanism. Therefore, the outer cylinder and the intermediate body sandwiched between the outer cylinder and the inner cylinder are not detached from the inner cylinder after being installed on the ground.
In addition, before installation on the ground, since each can be transported in a disassembled state, handling thereof is easy.

  Moreover, according to the structure for greening of Claim 3, in addition to the effect of the invention of Claim 1 and 2, since the intermediate body was formed by compressing the wood chip, the wood chip is excellent. The water retention effect can prevent the plant from drying more effectively. Moreover, the plant can be warmed more effectively in winter due to the high warming effect of the wood chip.

  Furthermore, according to the greening structure of claim 4, in addition to the effects of the inventions of claims 1 and 2, the intermediate is formed of water-permeable lightweight concrete. The hairline can be more effectively protected and weeds can be more effectively prevented from growing on the ground.

According to the greening structure composite according to claim 5, a plurality of the greening structures according to any one of claims 1 to 4 are integrally assembled in a planar shape. While exhibiting the effect similar to the invention of Claims 1 thru | or 4, a groove | channel can be formed between each structure for greening. Since the drainage is good due to this groove, it is possible to prevent the plant from being steamed. Therefore, it is possible to promote the growth of the plant and to perform the greening more effectively.
Moreover, since the structure which is for greening can be given flexibility by the groove which is the thin portion, even if there is an unevenness on the ground, it is deformed corresponding to it. Therefore, the entire surface of the composite can be reliably installed along the ground, and as a result, outflow of earth and sand can be prevented and greening can be favorably promoted on any ground.

  With reference to FIG. 1 thru | or FIG. 4, the structure 1 for greening which concerns on embodiment of this invention is demonstrated. FIG. 1 is a perspective view showing a greening structure. FIG. 2 is a sectional view taken along the line AA, and FIG. 3 is an exploded perspective view thereof. FIG. 4 is a side view showing a state in which a plurality of greening structures shown in FIG. 1 are installed.

  The greening structure 1 is installed on a slope and is used for greening while preventing the outflow of earth and sand. The greening structure 1 includes an inner cylindrical body 10, an intermediate body 20, and an outer cylindrical body 30. In this embodiment, in order to cover a wide range of slopes, a large number are arranged side by side without any gaps, and the flange portions 32 of the adjacent outer cylinders 30 are overlapped, and the four sides are fixed to the ground E with the pegs 34. Yes.

  The inner cylindrical body 10 is made of synthetic resin and has a cylindrical wall portion 13 erected from an upper end opening portion 12 formed at an upper end portion of a cylindrical main body portion 11 having a substantially truncated cone shape. This upper end opening 12 is a planting part. In addition, the inner cylinder 10 is filled with the culture soil S and the lower end portion is buried in the soil when installed. In addition, this inner cylinder 10 can also be made into a substantially truncated pyramid cylinder shape.

  The intermediate body 20 is fitted so as to cover the outer side of the inner cylindrical body 10, and has an insertion hole 21 through which the cylindrical wall portion 13 of the inner cylindrical body 10 is inserted at the upper end portion. Formed. The intermediate body 20 is fitted to the outside of the inner cylinder 10 and the outer cylinder 30 is fitted so as to cover the outside of the intermediate body 20. In addition, it is good to coat the surface of the outer cylinder 30 in order to improve durability.

The outer cylindrical body 30 is made of a mesh-like synthetic resin, is fitted so as to cover the outer side of the intermediate body 20, and has a substantially regular quadrangular pyramid cylindrical shape whose lower end portion is in contact with the ground E. Moreover, it has the hole part 31 which the cylinder wall part 13 of the inner cylinder body 10 which penetrates the insertion hole 21 of the intermediate body 20 penetrates further in the upper end part, and the flange part 32 faces outward at a lower end part. Around. The length of one side of the outer cylinder 30 is about 30 cm. The outer cylinder 30 may be substantially conical.
As the outer cylinder 30, for example, polypropylene having a function strong against ultraviolet rays is used.

  In addition, the cylinder wall part 13 of the inner cylinder body 10 and the upper end part of the outer cylinder body 30 are detachably assembled by an engagement mechanism. The configuration of the engagement mechanism is not limited. For example, as shown in FIG. 5, a substantially L-shaped assembly groove 14 is formed in the cylindrical wall portion 13, and the upper end portion of the outer cylinder 30 is formed in the assembly groove 14. It is conceivable to insert the protrusions 33 provided on the two or to form screws on the two and to screw the two screws together.

The greening structure 1 according to the present embodiment includes an inner cylindrical body 10 made of resin having a substantially truncated cone shape, an intermediate body 20 formed by compressing a wood chip, and an outer shape made of resin made of a substantially truncated pyramid shape. Since it comprises the cylindrical body 30, the structure is simple and lightweight. Therefore, handling is easy and construction can be performed very easily.
Moreover, since the lower end part of the inner cylinder 10 is buried in the soil, the lower end part serves as a weir, and the outflow of earth and sand can be prevented.

In addition, the greening structure 1 protects the hairline of the plant P extending from the upper end opening 12 by the three members of the inner cylinder 10, the intermediate body 20, and the outer cylinder 30.
In addition, since the plurality of greening structures 1 are installed side by side, a groove G is formed between them to improve drainage, thereby preventing root rot.

  Further, the three members 10, 20, and 30 prevent the ground E from being dried. In particular, since the intermediate body 20 is made of wood chips, the water that has passed through the mesh-like outer cylinder 30 is appropriately allowed to flow while retaining water, thereby preventing the plant P from growing and the roots from drying. Moreover, since the wood chip is also excellent in heat retaining properties, the plant P is effectively warmed in winter and promotes greening more effectively.

  Further, the greening structure 1 keeps the plant P warm in the winter by the three members 10, 20, and 30 and prevents weeds from growing on the ground E. Further, the soil rebounds due to rain. To prevent the lower leaves of the plant P from hurting. By these, the growth of the plant P can be promoted and greening can be effectively promoted.

In addition, since the structure 1 for greening is detachably assembled by the engagement mechanism, the cylindrical wall portion 13 of the inner cylindrical body 10 and the upper end portion of the outer cylindrical body 30 are installed on the ground E. The outer cylinder 30 and the intermediate body 20 are not detached from the inner cylinder 10. Therefore, the outflow of earth and sand can be reliably prevented and greening can be promoted well.
In addition, before installation on the ground E, the inner cylinder 10, the intermediate body 20, and the outer cylinder 30 can be transported in a disassembled state, so that handling thereof is easy.

Moreover, since the inner cylinder 10 is made into a substantially truncated-conical cylinder shape, and the surrounding wall is inclined in the mountain shape, the attitude | position after arrangement | positioning can be maintained stably over a long term. In addition, since the culture soil S filled in the inside has a mountain shape, it is difficult to collapse, and thus a stable posture can be maintained for a long time.
Further, since the outer cylinder 30 has a substantially truncated pyramid shape and the peripheral wall is inclined in a mountain shape, the posture after installation can be stabilized. Furthermore, since both the inner peripheral surface and the outer peripheral surface of the intermediate body 20 are mountain-shaped inclined surfaces, the post-arrangement posture can be stabilized.

  In addition, the intermediate body 20 can also be formed with water-permeable lightweight concrete instead of a wood chip. Thereby, high rigidity can be given to the intermediate body 20, the hairline of the plant P can be protected more effectively, and weeds can be more effectively prevented from growing on the ground E.

  Moreover, the structure 1 for greening which concerns on this embodiment is not limited to the use of a slope, It can also be used for the separation zone (flat ground) of a road. Also in this case, the above-described action can prevent the earth and sand in the separation zone from flowing out to the road, and can effectively promote greening.
