JPH074541U - Soil cover slope block - Google Patents

Abstract

(57) [Summary] (Modified) [Purpose] To protect slopes, achieve both harmony with the environment and reduction of construction costs. [Structure] A cross-shaped earth retaining wall 12 having a cruciform shape is erected on a block base 11 to form a slope block. [Effect] When the blocks are arranged, a small space is formed by the soil-holding walls of the four adjacent blocks, and the space can be covered with soil to grow grass and the like. In addition, this slope block is easier to remove from the die than a cylindrical block for covering with soil, and the manufacturing cost can be suppressed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a slope block that covers the soil and plants grass to cut out a landscape that blends in with nature, and can be used when protecting the slope on a dike or a step in a park.

[0002]

[Prior art]

 Cut-off mountain slopes and large river dikes are often covered with waterproof materials to protect the soil from softening due to rainwater. However, when covered with a waterproof material, there is a problem that plants cannot grow there. In particular, when concrete is used as a waterproof material for slope protection, the gray color of the concrete on the embankment is unbalanced with the surrounding landscape, and it is somewhat inorganic and lacks warmth, creating a sense of alienation. It came to be regarded as a problem as it brought up.

For this reason, recently, it has also been practiced to cover the slope with concrete or the like, cover it with soil, and then vegetate it with vegetation. However, on sloped slopes, the covered soil will be washed away by rain. Therefore, a method was adopted in which a concrete block with a shallow bottomed square tube was prepared, and this was spread over the slope, covered with soil from above, and held by the cylinder wall of the block. However, such a bottomed square tubular concrete block is unusually difficult to form as a concrete product for civil engineering, and since it has a concrete wall all around the bottom, its weight is only several hundreds. It had the drawback of reaching kg and making construction difficult.

[Problems to be solved by the device]

 Therefore, in the present invention, it is a technical subject to realize a block that has a function of holding covered soil, but is not difficult to manufacture or construct.

[0005]

[Means for Solving the Problems]

 Therefore, the means adopted in the present invention to solve the above-mentioned problem is that "the earth-covering retaining wall having a cruciform planar shape is integrally erected on a rectangular block base". If such blocks are spread with their sides aligned, the soil-holding walls of the four blocks, whose corners are in contact with each other, form a substantially rectangular tube-shaped wall to hold the covered soil. Further, since such a block does not have a concave portion that surrounds at least four sides, it is much easier to die-cut and is easier to manufacture than a bottomed tubular shape. Furthermore, the wall for holding the soil covered can be half the shape of a bottomed cylinder per block, and it is also lighter than conventional products.

【Example】

 Hereinafter, the present invention will be described based on embodiments.

The block 1 is obtained by pouring cement paste together with aggregate into a predetermined mold and solidifying. This block 1 includes a block base 11 in the shape of a square thin plate, which is partially chamfered, a soil cover holding wall 12 standing upright on the upper surface of the block base 11, and drainage groove forming projections 13 protruding from the four end surfaces of the block base 11.・ 13 ... Of these, the soil cover holding wall 12 has a cross shape that looks down from above from the center of a square block base with four perpendicular lines, and a large number of blocks 1, 1, ... When constructed, a space is created that is surrounded on all sides by the soil retaining walls 12, 12, ... Of the four blocks. Then, the soil can be retained in this space, and grass and other plants can be planted. Further, the drainage groove forming projections 13, 13 ... Are projections like vertically long columns arranged in pairs, and are adjacent to each other when a large number of blocks having the same shape are constructed side by side. The drainage groove forming projections 13, 13 ... of the block 1.1 abut against each other to form a gap between both blocks. The blocks 1, 1, ... Are fixed by placing cement in a portion of this gap excluding the pair of drainage groove forming projections. The drainage ditch forming projections without cementing are for drainage. Since it is narrow, a large amount of water cannot be drained, and drainage is not performed to the extent that it weakens levees. In such a block 1, the planar length of the soil cover retaining wall 12 is about half of the circumference of the block base, and if the conditions such as block base size, wall height, and concrete thickness are the same, the conventional It is possible to reduce the weight of the block having the same shape as the bottomed rectangular tube. Therefore, construction is easier than conventional products.

Since the soil is not a fluid, it is not necessary that the space for holding the soil be closed at all, and even if there is a gap between the soil retaining walls of the four blocks, the soil can be sufficiently used. Also in the above embodiment, a gap is formed between the soil cover holding walls.

[0009]

[Effect of device]

 As described above, since the block of the present invention employs the cross-shaped soil retaining wall, it can be manufactured and constructed more easily than the conventional products for the same purpose. Therefore, the block of the present invention has industrial utility value.
