DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope stabilizing block for stabilizing a slope, and more particularly to a slope stabilizing block used for relatively simple slope protection and embankment retaining walls. .

[0002]

2. Description of the Related Art A concrete block frame work has been developed in which concrete blocks are spread over a slope to prevent the slope from collapsing. As the concrete blocks, plate-shaped ones and various-shaped ones are adopted, and these are combined and arranged on the slope to hold the slope.

[0003]

[Problems to be Solved by the Invention] One of the problems to be solved in these concrete block frame works is
It means that the combined blocks tend to fall apart due to the large amount of rainwater that flows due to heavy rain. In a concrete block frame work, only adjacent blocks are aligned with each other and the connection is not strong. In many cases, there is no means for fixing the blocks to the ground, and the ups and downs of the ground greatly affect the connection between the blocks. For example, if a large amount of rain accumulates on the back side of the blocks or if the sand and sand flow due to the rain, the blocks may easily be disconnected and the entire structure may fall apart. Therefore, it was important that the rainwater flow well so that it does not collect on the back of the block or sediment.

Another problem to be solved by the present invention is to reduce the weight of the block. The block needs to manually lift the slope, and lifting a heavy block on a poorly sloped work is an extremely labor-intensive task, and has required many workers.

The present invention has been made to solve the above problems, and is a concrete block capable of improving drainage on slopes, and stable slopes that can be easily transported. The purpose is to provide a block for use.

[0006]

In the slope stabilizing block according to the present invention, a hole is formed at the center of a hexagonal plate-shaped body formed of a hardening material, and a hollow annular ring surrounds the hole. A pipe is arranged and embedded in the plate-shaped body. The holes may be perfectly circular or elliptical.
A steel or synthetic resin pipe can be used as the annular pipe. Since the steel pipe is bent in an annular shape, it is preferable to use a pipe having spiral irregularities formed around it. The spiral unevenness is crushed inside the ring and stretches outside the ring, which facilitates bending. On the upper three sides of the hexagonal plate-shaped main body, recessed engagement portions are recessed, and on the lower three sides, a ridge-shaped protruding portion is formed. Such retaining wall blocks are arranged along the slope, but after the installation, the annular pipe may be filled with a hardening material such as mortar.

[0007]

Since the hole is formed in the center of the plate-shaped body, rainwater does not flow out from the hole and collect on the back side of the block. Also, the water does not shed the soil behind the block. The hollow circular pipe reduces the weight and facilitates transportation. By filling the pipe with hardened material after installation, the weight can be increased and the ground can be pressed down firmly. The blade part meshes with the meshing part, and the blocks do not easily shift from each other.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on an embodiment shown in the drawings. In the figure, reference numeral 1 is a slope stabilizing block according to the present invention, and a plate-shaped main body 2 has a hexagonal plate shape. A circular hole 3 is formed at the center of the plate-shaped body 2. The plate-shaped body 2 is made of concrete, and an annular pipe 4 is embedded inside so as to surround the periphery of the hole 3. The annular pipe 4 uses a steel hollow sheath, and spiral irregularities are continuously formed in the circumferential direction around the sheath. Circular pipe 4
When it is bent, the unevenness located outside the ring extends and the unevenness located inside shrinks, allowing bending.

In FIG. 1, a valley-shaped recessed meshing portion 5 is continuously formed on the upper three sides of the slope stabilizing block 1, and a ridge shape is formed on the lower three sides. The blade portion 6 is formed continuously. On the back side of the slope stabilizing block 1, a plurality of U-shaped steel fasteners 7 partially embedded in the plate-shaped main body 2 are projected.

An example of construction using the slope stabilizing block 1 as described above will be described. The embodiment in FIGS. 3 and 4 is one in which the retaining wall block 1 is continuously laid on the ground of a slope. When installing the slope stabilization block 1,
The slope stabilizing block 1 with the lower blade portion 6 located therebelow
Try to fit in the meshing part 5 of. The slope stabilizing block 1 located at the bottom is a foundation portion 8 formed under the slope 1.
Receive by. The meshing of the blade portion 6 and the fitting portion 5 reduces the possibility that the blocks 1 and 1 adjacent to each other in the upper and lower sides or in the left and right sides are separated. Block 1 In this way, a plurality of slope stabilizing blocks 1 are laid adjacent to each other without a gap. The central hole 3 is vegetated to improve the landscape of the entire slope. Even if it rains, rainwater does not flow out from the hole 3 to prevent water from accumulating on the back side of the block 1 or pushing away sediment.

The embodiment shown in FIG. 5 and FIG. 6 is a case where a retaining wall work is performed on the embankment, and a plurality of slope stabilizing blocks 1 are passed through pipes 9 through fasteners 7 on the back side of the slope stabilizing block 1. To connect. On the back surface of the block 1, a wire net 12, a synthetic resin net, a water-permeable sheet, or the like is arranged in order to prevent water from spilling through the holes 3 and allowing only water to escape. A strip-shaped anchor 10 such as a synthetic resin cloth is folded and hung on the pipe 9 to extend the strip-shaped anchor 10 onto the embankment 11 behind the block 1. Embankment 11 is applied on this to embed the band-shaped anchor 10. Next, the slope stabilizing block 1 is stacked on the slope stabilizing block 1. After that, the steps described above are repeated to complete the construction of the entire retaining wall.

The above construction is for laying on a slope or for retaining walls in embankments. In either case, the annular pipe 4 is buried inside the block 1 and is lightweight and extremely easy to work. Is. However, even if one of the slope stabilizing blocks 1 is provided with a hole communicating with the annular pipe 4 and a hardening material such as mortar is filled into the annular pipe 4 through the hole after installation or installation. Good. As a result, the weight of the block 1 becomes heavier, and the ground can be held down more firmly.

[0013]

The present invention has the above-described configuration, and can obtain the following effects. Since the slope stabilizing block is circular and complete as a structure, it is structurally stable and has a structural strength as a single unit. The slope stabilizing block has a hollow annular pipe embedded therein, the weight of the block is lightened, the work such as transportation is significantly facilitated, and the number of workers can be reduced. Since a circular hole is formed in the center, even if it rains, it is unlikely that rain will flow through the hole and collect on the back side of the block or push away the sediment behind it, and the block will not fall apart. The central hole can be vegetated to improve the landscape of the entire slope. The hole is not a square such as a square or a hexagon, but a circle such as a perfect circle or an ellipse, and has structurally high strength characteristics and does not impair the strength of the block. On the upper three sides of the hexagon, the meshing parts that are recessed in a valley are recessed, and on the lower three sides, the blades that project in a ridge are formed, so when arranging the hexagonal blocks side by side, Not only the top and bottom but also the adjacent blocks are connected by the meshing of the meshing part and the blade part, there is no displacement of the block at the time of installation, and the blocks are unlikely to fall apart even if the ground rises and falls slightly. Since the blade portion meshes with the meshing portion, work can be performed from any position, so construction is easy. After installing the block on the slope, you can fill the inside of the annular pipe with hardening material to increase the weight of the block itself,
As a result, the slope can be pressed more firmly.
