Description

Retaining wall block capable of stacking transverse waves}

The present invention relates to a retaining wall block capable of building transverse waves.

In general, a retaining wall block is a member used to construct a retaining wall structure constructed to prevent collapse due to soil outflow of a built-up land such as a road, a river, or an embankment, or to protect the built-up land.

When constructing the retaining wall structure, a plurality of retaining wall blocks are installed in a transverse row on the bottom side of the castle ground, and then a plurality of retaining wall blocks of the same shape are stacked on the upper surface of the retaining wall block installed in a transverse row to construct the retaining wall structure.

At this time, a reinforcing material such as a geogrid is installed to prevent the constructed retaining wall structure from overturning. It prevents the constructed retaining wall structure from overturning.

Here, retaining wall blocks having various structures have been developed to prevent the collapse of the constructed retaining wall structure by easily and firmly coupling the retaining wall blocks.

As a retaining wall block for constructing a conventional retaining wall structure, there is Korean Patent Registration No. 10-0430530 (retaining wall block/2004.04.26), which has side protrusions and side grooves on the same line on both sides of the retaining wall block, respectively. A technology is disclosed in which blocks for retaining walls are interlocked and connected to each other through this, and a plurality of blocks for retaining walls are stacked so as to be firmly coupled to each other alternately from side to side thereon.

According to the prior art, the safety of the retaining wall structure, such as preventing collapse of the retaining wall structure by preventing the retaining wall block from moving forward or side-front by the pressure from the rear to the front of the retaining wall structure constructed by the retaining wall block, In addition, there is an advantage in that blocks for retaining walls can be easily installed even in a straight or arc-shaped embankment or a cut part by easily installing blocks for retaining walls interlocking in a row in a straight or linear form.

However, in the prior art, as the side protrusions and the side grooves are formed on the same (horizontal) line, it was difficult to build the retaining wall blocks in a wavy shape even if they were built in a straight line up and down or retreated. Research on retaining wall blocks and construction methods has been actively conducted up to now.

Referring to FIG. 6C, when the retaining wall blocks are repeatedly constructed along the transverse direction as described above, the surface of the front wall 12 of the second retaining wall block 1' is higher than the surface of the front wall 12 of the first retaining wall block 1. As it is located at the rear, the surface of the rear wall 13 of the second retaining wall block 1' is more protruded to the rear than the surface of the rear wall 13 of the first retaining wall block 1, thereby protruding in the transverse direction. The wavy shape is completed naturally.

Referring to FIG. 6D, on the other hand, when the lateral construction of the first and second retaining wall blocks (1,1') is completed, a new first retaining wall block ( 1) and the second retaining wall block 1' are stacked alternately.

* Next, the front wall of the first retaining wall block 1 ( As the surface of the front wall 12 of the second retaining wall block 1' is located rearward than the surface of 12), the surface of the second retaining wall block 1' is rearward than the surface of the rear wall 13 of the first retaining wall block 1 The first retaining wall block (1) and the second retaining wall block (1') are repeatedly constructed horizontally so as to protrude further.

Referring to FIG. 6E, a pin 50 is then inserted through the rubble filling space 11 of the first and second retaining wall blocks 1 and 1' located at the top, and the first and second retaining wall blocks located below are located below.

The rubble filling space 11 of the first and second retaining wall blocks 1 and 1' is filled with rubble.

When the retaining wall blocks are constructed in the above manner, wave patterns are naturally completed along the transverse and longitudinal directions, as shown in FIG. 6f.

On the other hand, if necessary, one end of the geogrid may be inserted between the lower retaining wall block and the upper retaining wall block, and the other end of the geogrid may be buried in the embankment or cut portion CA to prevent the retaining wall block from overturning.

On the other hand, when the front projection 20 of the second retaining wall block 1' disposed adjacent to the coupling groove 30 of the first retaining wall block 1 is coupled, the rear wall 13 of the first retaining wall block 1 ), the surface of the second retaining wall block 1' protrudes more rearward than the surface, and accordingly, there is an inconvenience in digging the embankment or cut portion CA by the protruding length of the second retaining wall block 1'. .

Referring to FIG. 7, the second retaining wall block 100 in which the length (L': see FIG. 4) of the block body 10 is formed as short as the thickness of the front projection 20 is replaced with the second retaining wall block 1'. When applied to construction instead, when the first retaining wall block 1 and the second retaining wall block 100 are combined, the rear wall 13 of the first retaining wall block 1 and the rear wall of the second retaining wall block 100 ( In 13), since the planes are located on the same (vertical) line, it is possible to solve the construction inconvenience of having to dig the embankment or cutting section (CA) during the construction process.

Although the present invention has been described in detail only for the specific embodiments described, it is natural for those skilled in the art that various modifications and variations can be made within the scope of the technical idea of the present invention, and it is natural that such variations and modifications fall within the scope of the utility model claims. will be.
