The present invention relates to a retaining wall block, and more specifically, to a retaining wall block that prevents the sediment of the inclined surface during the filling work, such as the construction of rivers, banks, roads, housing site complexes.

In general, the soil particles themselves are solid, but are easily separated as discontinuities rather than crystals such as steel or concrete, and are easily changed by external forces.

Therefore, when the land works such as the construction of rivers, banks, roads, housing complexes, etc., the sediment of the earth and sand is suppressed by building retaining walls made of steel or synthetic fibers such as blocks, flagstones and panels.

A conventional retaining wall block having a shape used in constructing such a retaining wall is shown in FIG. 1, and the structure and operation of the conventional retaining wall block will be described as follows.

As shown, the conventional retaining wall block is provided with a body portion 21 including side surfaces 22 and 23 extending rearward from the ends of the front face 11, the top face 31, and the bottom face 41. .

The body portion 21 is formed with first and second holes 32 and 33 spaced apart from each other by a predetermined distance on the upper surface 31 of the inner side from both side surfaces 22 and 23, and the first and second holes ( The first and second pin holes 34 and 35 are formed to accommodate the pins (not shown) that connect the blocks up and down adjacent to the 32 and 33 to form a unit for the retaining wall block.

Here, the first and second holes 32 and 33 are formed in the upper surface 31 of the trunk portion 21 in the shape of an approximately bow-shaped groove, and the first and second pin holes 34 and By supporting the lower end of the pin inserted in 35, a plurality of blocks can be built.

In the drawings, reference numerals 51 and 52 denote central portions and rear portions extending from the trunk portion of the retaining wall block.

Retaining wall construction work using such a conventional retaining wall block usually positions the retaining wall block horizontally, and then places a separate other retaining wall block on the upper surface thereof while staggering from the block. At this time, the position of the first and second pin holes formed in the lower retaining wall block is positioned on one lower surface of the first and second holes formed in the retaining wall block of the upper layer. That is, the first pin hole formed in the lower retaining wall block has a lower surface of the second hole formed in the retaining wall block, and the second pin hole formed in the lower retaining wall block has an upper retaining wall block. By being located on the lower surface of the formed first hole, two retaining wall blocks are positioned adjacent to the upper surface of the retaining wall block of the lower layer.

In addition, when the retaining wall blocks are constructed with a predetermined inclined surface, the retaining wall block in the upper part is retracted slightly back than the lower retaining wall block in order to be constructed. In this case, the first and second pin holes of the lower layer The position of the first layer and the second hole of the upper layer is parallel to the upper and lower positions, and the first and second pin holes of the lower layer to be located on either side of the first and second holes of the upper layer.

That is, the first and second pins inserted into the first and second pin holes of the lower layer are positioned at the rear end of the first and second holes of the upper layer, so that the retaining wall having a predetermined inclination angle is formed by retreating the upper layer slightly backward. Is built.

On the other hand, the retaining wall blocks may be further firmly supported by the grid by inserting one end of the grid (not shown) in the first and second pins which connect and support the block to the block. have.

However, the conventional retaining wall block has a very small diameter or outer diameter of the first and second fins, which is the most important means for supporting the upper and lower layers by connecting the upper and lower layers, and the lower end of the first and second fins. Since the width of the first and second pin holes to be fixed is small, the force supporting the lower ends of the first and second pins is also weak. Therefore, when the external force due to earth and sand acts largely, the first and second pins may be broken or cracks may occur, and the retaining wall block may move uniaxially while the lower ends of the first and second pins are separated from the first and second holes. May be broken or collapsed.

In addition, while the retaining wall block weighs approximately 40 to 55 kg, the diameters or widths of the first and second pin holes and the first and second holes formed in the retaining wall block are very narrowly formed, so that an operator can construct the block. In the meantime, it is very difficult to accurately match the positions of the first and second pin holes formed in the lower layer and the first and second holes formed in the upper layer.

In addition, when constructing the inclined retaining wall, the retaining wall block of the upper layer should retreat back slightly, and the first and second pin holes and the first and second holes of the lower layer and the upper layer should be properly aligned. Since it is not easy to align the positions of the holes and the first and second holes in the upper layer, the retaining wall construction work is very difficult.

Therefore, the present invention is designed to solve the conventional problems as described above, so that the retaining wall block that can increase the coupling force or support force between the retaining wall blocks to be built, so as to increase the resistance to the force to flow down the soil. To provide.

And another object of the present invention to provide a retaining wall block that can be naturally curved in the axis of the connecting bar in the form of a curved block.

In addition, another object of the present invention is to provide a retaining wall block capable of selectively constructing vertical and inclined (retreating) retaining walls by simply operating the same connecting rod.

Another object of the present invention is to connect and support the lower retaining wall block and the retaining wall blocks up and down so that the up and down construction of the retaining wall block can be easily performed and the working time can be shortened. It is to provide a retaining wall block that can easily check the position of the connecting means (connection rod).
