Description

【考案の詳細な説明】河川敷、提防等の護岸被覆については種々の形
状のコンクリートブロツクが使用されて護岸の目
的が達成されているが、コンクリートブロツクに
より被覆された区域はその緑地化が困難である。[Detailed explanation of the invention] Concrete blocks of various shapes are used to cover riverbeds, embankments, etc. to achieve the purpose of revetment, but it is difficult to green the areas covered by concrete blocks. be.

ある。 The purpose of this proposal is to achieve both the purpose of revetment or similar purposes and the purpose of greening by using concrete blocks (hereinafter simply referred to as blocks) that are easy to manufacture and handle. The following is an explanation of the covering device for greening the slope of the slope with reference to the diagram.

するため、２個のブロツク２ａ，２ｂが交叉斜線
を入れて示される。 In FIG. 1, 1 is an area to be greened, and grass is planted in this area 1. Below area 1, a block assembly structure 3 is formed by connecting blocks 2 with reinforcing bars as shown by dotted lines. FIG. 2 is a drawing showing the assembled structure 3 excluding the embankment. In this drawing, the connecting reinforcing bars 4 are shown, and in order to clarify the outline of the block 2 in plan view, two blocks 2a, 2 are shown. 2b is shown cross-hatched.

部８，９上の孔１０を貫通させられる。 The shape of block 2 is shown in FIGS. 3-5. In these figures, Figure 3 is a plan view and Figure 4 is a plan view.
Figure 5 shows the - line in Figure 3, respectively.
- It is a sectional view seen from the line direction. The block 2 is rod-shaped and has a narrow top ridge 5 and slopes 6 and 7 extending downward from both sides of the top ridge 5 over the entire longitudinal length of the block. It has enlarged cross-sectional parts 8 and 9 at a plurality of locations, the width and cross-sectional area of which are larger in the direction perpendicular to the direction of the part 5 than the remaining parts. The reinforcing bars 4 shown in FIG. 2 are passed through holes 10 on the enlarged sections 8, 9.

ブロツク２は、第２図に示す如く長手方向の位
相をずらせて配置される。 The blocks 2 are arranged out of phase in the longitudinal direction as shown in FIG.

が盛り土１１内に残らないようにする。 The enlarged cross-sectional parts 8 and 9 are parts for connecting the blocks, and also form a space 12 through which excess moisture contained in the mound 11 escapes underground, as shown in FIG. The slope portions 6 and 7 provided along the entire length of the block 2 in the longitudinal direction allow excess moisture to quickly flow out through the space 12 and prevent excess moisture from remaining in the embankment 11.

盛り土１１の厚さは、土の運搬の手間を可及的
に少くするため、比較的薄くされ、頂稜部５の直
上において例えば５−６cm程度とされる。 The thickness of the mound 11 is made relatively thin, for example, about 5 to 6 cm directly above the top ridge 5, in order to minimize the labor involved in transporting the soil.

以上において説明した本案による緑地化用被覆
装置の利点は、盛り土を施されたブロツク群の組
立構造体が、盛り土に植えられた芝に生育に適し

が容易であると共にブロツク群が安定状態をなが
く保つ点にある。 The advantage of the covering device for greening according to the present invention explained above is that the assembled structure of blocks covered with earth provides an environment suitable for growth of grass planted in the earth, and the work required to assemble blocks It is easy to do this, and the block group maintains a stable state for a long time.

なお、本案は宅地に対しても適用することがで
きる。 This proposal can also be applied to residential land.
