Abstract

PROBLEM TO BE SOLVED: To carry out laying execution economically and easily by installing frame bodies on the adjacent two sides of a square-shaped block formed of porous permeable concrete and forming the frame bodies so that the frame bodies on the two sides are bitten to the other two sides of the adjacent blocks one another when the blocks are arranged. SOLUTION: The square-shaped block 2 is formed of porous permeable concrete. L-shaped sectional frame bodies 5 in proper width and height are mounted on adjacent two sides, and the frame bodies 5 are laid so as to be mutually bitten to the other two sides 6 of the adjacent blocks 2 when a plurality of the blocks 2 are disposed. Accordingly, the usage of cement can be economized rather than concrete and the blocks are economical because the blocks are structurally simple and are manufactured easily and the porous permeable concrete is used, and the execution process of the blocks is simplified because the blocks are laid by the simply laying method only of laying on a slope face of each block, the lining of the slope face and vegetation, thus obtaining an economical working method.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an economical slope protection block for earth covering and a method of laying the slope, which can maintain a required strength on a slope and can maintain vegetation for protecting the slope. .

[0002]

2. Description of the Related Art Conventionally, a dirt sucking prevention sheet is laid on a slope, and a grid-shaped slope protection frame is installed thereon, and a chestnut stone is spread between the grid frames, and an appropriate thickness is placed thereon. There is a slope protection method in which soil is applied and vegetation is laid thereon, or a lattice frame is filled with coarse bagged soil and vegetation is vegetated on the surface of the bag.

[0003] In addition, soil covering is applied to the covering protection block 1 used for protection of the slope, for example, as shown in the plan view of FIG. 7, the front view of FIG. 8, and the side view of FIG. It has also been done.

[0004] However, in the case of installing the grid-shaped slope protection frame as described above or in the case of the slope protection coating block 1 in Fig. 7, the slope is protected by a concrete block and the soil is further covered thereon. Because the soil is vegetated on the ground surface, it looks strong and has a natural slope. Rainwater cannot penetrate into the soil layer under the block.

[0005] In the dry season, since the cover layer on the block has a small cover layer thickness, the cover layer may be dried and vegetation may be lost. On the other hand, buried type slope protection articulated concrete blocks that cover the slopes and plant vegetation are not visible to the public, so the purpose is to protect the slopes and the required strength is sufficient, so it is as economical as possible. Things are desired.

[0006]

DISCLOSURE OF THE INVENTION The present invention can provide a slope with a required strength and a drainage effect capable of maintaining vegetation on the slope. Provided are a slope protection block for earth covering and a method for laying the blocks, which can lay the blocks economically and easily.

[0007]

The slope protection block for earth covering according to the present invention comprises a frame having a cross section of an appropriate width and height on two adjacent sides of a quadrangular block formed of porous permeable concrete. And a soil covering slope protection block formed so that the frame on the two sides meshes with the other two sides of the adjacent block when a plurality of the blocks are arranged, and the soil covering method according to the present invention. When laying the surface protection block, a plurality of quadrangular blocks formed of porous permeable concrete are arranged side by side on the slope, and when laying, the appropriate width and height provided on the two adjacent sides of the block quadrilateral Laying the frame of the cross section of the above so as to mesh with the other two adjacent sides of the quadrilateral of another adjacent block, and covering the blocks with an appropriate thickness of soil. Vegetation on cover soil It consists of.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a slope protection block for covering soil in the embodiment, and FIG. FIG. 2 is a side cross-sectional view in the −C direction. As shown in FIGS. 1 and 2, the block 2 is formed of porous permeable concrete and has four sides such as a square or a rectangle having an appropriate size and thickness. As shown in the plan view of FIG. 3 and the sectional side view in the DD direction of FIG. 4, a plurality of blocks 2 are laid side by side on a slope 4 such as a riverbed.

Therefore, as shown in FIGS. 1 and 2, an L-shaped frame body 5 having a cross section of an appropriate width and height is provided on two adjacent sides of the quadrangular block 2, as shown in FIGS. As shown in FIG. 4, when the plurality of blocks 2 are arranged, the L-shaped frame 5 is laid so as to mesh with the other two sides 6 of the other adjacent blocks 2. In FIG. 2,
When the L-shaped frame 5 engages with the other two sides 6, the frame 5
May be provided at the lower part of the block 2 so that one of the adjacent blocks 2 meshes with the other block 2 so as to ride on the other through the cut 7.

Also, depending on the size of the block 2,
When reinforcement is required, a reinforcing portion 8 as shown in the figure can be provided. As described above, by manufacturing the block 2 from porous permeable concrete, it is possible to secure the vertical movement of water between the upper and lower soil layers of the block 2 and to form the water permeable layer by the blocks 2 connected side by side. Face 4
Allows for drainage.

Further, on two sides 6 of the adjacent block 2,
When a plurality of blocks 2 are laid on the slope 4 while being engaged and connected so that the frame 5 of the other block 2 rides thereon, not only does the natural slope cover the slope 4 with a concrete plate, Thus, a grid-like frame structure is formed by the grid-like frame bodies 5 of the adjacent blocks 2 to provide a strong protection body for the slope 4 as a whole with a simple structure.

Further, by forming each block 2 of porous permeable concrete, the coefficient of friction of the bottom surface of the block 2 to be laid increases, and the sliding resistance against the slope of the slope 4 increases. Next, in FIG. 4, an example is shown in which a plurality of blocks 2 are laid on the inclined slope 4 while being connected to each other, a cover soil 9 of an appropriate thickness is applied thereon, and vegetation is indicated on the top by 10. The frame 5 of the block 2 laid flat on the sloped slope 4 can sufficiently prevent the upper cover soil 9 from sliding.

In FIG. 5, when the slope protection block for covering soil of the present invention is laid to protect the slope 4 having a steep slope,
An example is shown in which an appropriate hole 11 is made in the block 2 and a reinforcing log 12 is cast in order to connect the block 2 with the lower layer laying surface.

FIG. 6 shows a multi-natural type by applying a cover 9 and vegetation 10 on each of the blocks 2 of the cover slope protection block of the present invention inside the slope of the soil blade. The example applied to river making is shown, and the bottom of block 2 is fixed with foundation concrete 13.

[0015]

The slope protection block for covering soil according to the present invention described above is structurally simple and easy to manufacture.
Moreover, because it uses porous permeable concrete,
It is economical because it saves the amount of cement used compared to concrete.Since the blocks are laid by a simple laying method of laying the above blocks on the slope, covering the soil and vegetation, the construction process is simplified. Therefore, it becomes an economical work method.

Further, the slope protection block of the present invention has a frame structure in which the L-shaped frames provided on two sides of each block are combined as a whole in a lattice shape, and a strong framework can be constructed on the slope. it can. Furthermore, since each block is made of porous permeable concrete, a water-permeable layer is formed at the bottom of the slope to improve the drainage effect of the slope, while in the dry season, the water in the soil layer under the block becomes capillary phenomenon. As it rises to the surface, it will help maintain vegetation.
