  The present invention relates to a vegetation conservation block for protecting soil and greening. In particular, the present invention relates to a plant capable of preventing plant lodging. Moreover, it is related with the construction method of the vegetation maintenance block which spreads a vegetation maintenance block in a waterfront part.

  Reed, which has been used for a long time as a roofing material for thatched roofs, is not only used as a raw material for firewood, but also for the environment of rivers and marshes because of its water purification. It attracts attention as a plant to be preserved or improved. On the other hand, however, the reed field, where wild reeds are vegetated, has shrunk year by year due to the effects of river construction that has been actively carried out in recent years and the traveling waves that occur when ships pass through. It has become a thing. For this reason, constructing a vegetation conservation block having a structure suitable for the growth of reeds at the watersides of rivers, marshes, and the like to create reed fields.

  For example, in Japanese Patent Laid-Open No. 10-280417 (Patent Document 1), a suction prevention mat made of a durable fiber material that can be laid on a slope of a waterside and a suction prevention mat are laid. It consists of a bottomed concrete frame, a vegetation mat with a pocket hole stored in the concrete frame, and a pot seedling planted in the pocket hole of the vegetation mat. A waterside block vegetation structure is described in which a small hole for drainage is established. As a result, it is said that it becomes possible to prevent scouring of slopes and to plant waterside plants such as reeds in places with water currents. At this time, it is also described that a lid having an opening corresponding to the pocket hole of the vegetation mat stored in the concrete frame is placed on the concrete frame so as to cover the vegetation mat. As a result, it is said that the growth base material and pot seedling can be prevented more effectively.

  When a plurality of vegetation conservation blocks of the present invention are laid, the plant support of one vegetation conservation block is connected to the plant support of another vegetation conservation block laid around the one vegetation conservation block. Thus, a vegetation space surrounded by the plant support is formed between the plant supports. Thereby, it becomes possible to effectively use the space outside the plant support as a vegetation space without waste.

  As a suitable embodiment of such a vegetation maintenance block, as shown in FIGS. 1-3, the planar view shape of a plant support body is the character of a "well" shape (well character type), and FIGS. As shown in FIG. 9, the plant support has a “10” -shaped shape (cross-shaped type) in plan view. In the following, the explanation will be focused on the well-shaped vegetation conservation block, but the configuration mentioned therein cannot be adopted in the cross-shaped vegetation conservation block. Unless it is obvious from the gist of the present invention, it can also be adopted in a vegetation conservation block of a cross-shaped type.

  As shown in FIGS. 1 to 3, the well-shaped vegetation maintenance block 10 is formed by arranging a plant support 20 having a shape of “well” in a plan view on the upper side of the base 40. The plant support 20 and the base 40 may be formed separately, but in the present embodiment, each is formed integrally. Normally, the vegetation maintenance block 10 is formed by pouring a material into a mold and solidifying it. As the material to be solidified, it is preferable to use concrete in consideration of strength and durability. When it is desired to further improve the strength of the vegetation maintenance block 10, a reinforcing material such as a reinforcing bar may be provided inside the material.

  The plant support 20 has a function as a partition for forming a vegetation space suitable for growing tall plants such as reeds, and is input to the stem part of the plant growing in the vegetation space or the vegetation space. It is intended to support stones that have been made. The plant support 20 may form a vegetation space by a plurality of vertical walls. However, the plant support 20 according to the present embodiment has four pillars 21 and four integrally formed. A vegetation space is formed by the beam portion 22 and the eight convex portions 23. Among these, the beam part 22 and the convex part 23 mainly support the stem part of a plant. The plant support 20 can function most of the space above the base 40 as a vegetation space.

  Inside the plant support 20, as shown in FIG. 2, a hollow portion 60 having an open top is formed. Since the hollow portion 60 is surrounded by the beam portion 22, the hollow portion 60 is suitable as a vegetation space in which tall plants such as reeds grow. A plurality of hollow portions 60 may be provided inside the plant support 20. Although the shape of the hollow part 60 is not specifically limited, It is preferable that it is a shape where the horizontal cross section becomes wider, so that it becomes an upper side. This is because the hollow portion 60 is usually formed by pulling the mold upward, but by using such a shape, the mold can be easily removed.

  Further, outside the plant support 20, a space 61 in which three sides (actually surfaces) are formed by one beam portion 22 and two convex portions 23, and two sides (actually) by the two convex portions 23. And a space 62 in which a surface) is formed. As shown in FIGS. 4 and 5, these spaces are surrounded by a plant support by combining with other spaces arranged around when a plurality of vegetation conservation blocks 10 are laid. Vegetation space. In FIG. 5, the vegetation space completely surrounded by the plant support is indicated by hatched portions.

  As shown in FIG. 3, an opening 24 penetrating in the horizontal direction is formed between the four pillar portions 21 of the plant support 20. Thereby, the plant growing in the vegetation space can not only extend the root in the horizontal direction but also entangle the root in the pillar portion 21. In addition, it is possible to secure soil connection and water permeability in the horizontal direction and make each vegetation space more suitable for growing plants. Although the shape of the opening part 24 is not specifically limited, It is preferable that it is a shape where the vertical cross section becomes wide, so that it becomes an outer side. The opening 24 is usually formed by pulling the mold outward in the horizontal direction, but by using such a shape, the mold can be easily cut. Between the convex part 23 and the base | substrate 40, when the several vegetation maintenance block 10 is spread | laid, the space 25 which has an effect similar to the opening part 24 can be formed.

  The base 40 can prevent the soil on the construction surface from flowing out and can stably install the vegetation conservation block 10. In this embodiment, the planar view shape of the base 40 is a square as shown in FIGS. The base having a square shape in plan view is preferably combined with a plant support having a shape of “well” or “ten” in the shape of plan view. Further, as shown in FIG. 2, a vertical through hole 41 is provided at the center of the base 40. Thereby, the plant growing in the vegetation space can extend its root deeply into the soil below the base 40. The shape of the through hole 41 is not particularly limited, but it is preferable that the horizontal cross section becomes wider as it goes upward. This is because the through-hole 41 is usually formed by pulling the mold upward, but by using such a shape, the mold can be easily removed. In this embodiment, the through-hole 41 has a circular taper shape with an opening on the upper surface side of the base 40 having a diameter of 140 mm and an opening on the bottom surface side of the base 30 having a diameter of 80 mm.

  As shown in FIGS. 1 to 3, vertical grooves 42 and 43 are provided at the edge of the base 40. The through groove 42 is provided in a side portion of the base 40, and the through groove 43 is provided in a corner portion of the base 40. As shown in FIGS. 4 and 5, these through grooves are combined with other through grooves when a plurality of vegetation maintenance blocks 10 are laid, thereby forming new through holes at the boundary portions of the bases. Thereby, it is possible to form a vertical through hole having the same function as the through hole 41 also under the vegetation space newly formed outside the plant support 20. The dimensions and shape of the through grooves 42 and 43 are not particularly limited, but in this embodiment, the horizontal cross section of the through grooves 42 is a semicircular shape with a diameter of 100 mm, and the horizontal cross section of the through grooves 43 has a diameter of 200 mm. And it has a fan shape with a central angle of 90 degrees.

  As shown in FIGS. 1 to 3, a connection ring 50 is provided at the peripheral edge of the vegetation maintenance block 10. Thereby, it becomes possible to mutually connect and fix a plurality of vegetation maintenance blocks 10. The connection ring 50 may be provided at the peripheral edge of the plant support 20, but in the present embodiment, the connection ring 50 is provided at corners (four corners) of the base 40. The reason why the four vegetation maintenance blocks 10 are connected at one place is not the side of the base 40 but the corner. In the present embodiment, the connecting ring 50 is used, but the present invention is not limited to this, and various connecting members can be used. The vegetation maintenance block 10 is preferably connected by connecting a wire rope (not shown) through the annular portions of the plurality of annular fittings. Thereby, it becomes possible to connect several vegetation maintenance blocks 10 easily.

Referring to FIG. 5, the well-shaped vegetation conservation block 10 of this embodiment is It can be seen that four vegetation spaces can be formed per block. That is, the well-shaped vegetation conservation block 10 has four, four, four spaces 61 that form one vegetation space by combining one or two hollow portions 60 that form one vegetation space. It has four spaces 62 which form one vegetation space by combining them (FIG. 2). Moreover, the plant support 20 which forms each vegetation space does not overlap twice at the boundary part of each vegetation space, but is single at every boundary part. It can also be seen that it is excellent in terms of securing and strength.

The size of the vegetation space formed by the plant support 20 varies depending on the type of plant grown there, and is appropriately adjusted. The height of the plant support 20 is usually set to 100 to 500 mm. In particular, when growing plants such as reeds, it is preferably 200 to 400 mm. In this embodiment, the height of the vegetation space is 300 mm. Moreover, when the planar view shape of the vegetation space is assumed to be a square, the length of one side is usually 200 to 1000 mm. In particular, when growing plants such as reed, it is often 700 mm or less. In this embodiment, the length of _{L 3} shown in _L length of ₂ is a 540 mm, also 5 shown in FIG. 5 has a 300 mm.

The dimensions of each part of the plant support 20 such as the height of the column part 21, the length of the beam part 22, or the length from the proximal end to the distal end of the convex part 23 are matched to the dimensions of the desired vegetation space Adjusted. Moreover, although the dimension of the base | substrate 40 is also adjusted so that it may correspond with the dimension of the plant support body 20, in this embodiment, the planar view shape is a square whose one side is 1000 mm. Other length of L ₁ shown in FIG. 5 (the width of the beam portion and the convex portion) varies depending on the and the length of the beam portion 22, in this embodiment, is about 80 mm.

  10 and 11 show a state in which the cross-shaped vegetation maintenance blocks 11 shown in FIGS. 7 to 9 are spread. In FIG. 11, the vegetation space completely surrounded by the plant support 30 is indicated by the hatched portion. When FIG. 11 is seen, it turns out that the vegetation maintenance block 11 of the cross-shaped type of this embodiment can form two vegetation spaces per block. That is, the cross-shaped vegetation conservation block 11 has four spaces 63 that form one vegetation space by combining two. In addition, the plant support 25 that forms each vegetation space is not doubled at the boundary part of each vegetation space, but is single at all the boundary parts. This vegetation conservation block 11 is also well-shaped. Similar to the type of vegetation conservation block, it can be seen that it is excellent in terms of securing vegetation space and strength. The cross-shaped vegetation conservation block 11 usually has a smaller number of vegetation spaces than the well-shaped vegetation conservation block 10, but the size is reduced accordingly.
