Description

Oil mass block for front side vegetation and Retaining wall using the same}

The present invention relates to a reinforcement soil block for constructing a retaining wall by being built on a slope such as a cut slope, and more particularly, the installation is simple and improves the rigidity of the retaining wall effectively by securing the stability of the slope such as the cut slope. The present invention relates to a full vegetation reinforcement soil block and a retaining wall structure using the same, which have a wide range of applications and have improved beautification and commerciality.

In general, slopes such as cut slopes exist mostly in riversides, lakes, or hills (flats, apartment complexes, etc.) or roads where roads are constructed.

Since such cut slopes are formed by artificial cutting work, slopes such as slopes lose their balance and are dangerous. Also, due to the low cohesiveness of the soils, the slopes are easily broken down and cause a situation. To prevent the loss of earth and sand or other situations.

As a plan for reinforcing slopes such as cut slopes, reinforced concrete retaining walls have been widely used in Korea, which not only consumes enormous cost and time for forming and curing the reinforced concrete structure, but also enormous cost for excavation and fill work. In addition, since there are many limitations for large-scale cutting work, about 15 years ago, the technique of constructing retaining wall by embedding soil in the anchor bolt site while constructing the structure in which the anchor bolt is integrated was introduced in Japan. It is implemented. However, this reinforcement method also has a disadvantage in that a large amount of cost is consumed in gulting and filling work, and the structure as a whole becomes large.

In order to improve this problem, structures of retaining walls are formed by stacking retaining wall blocks coupled with steel reinforcement materials and reinforcing cut slopes through such retaining wall structures.

That is, as disclosed in Korean Patent Publication No. 0372821, the reinforcing structure of a cut slope using a conventional retaining wall block is provided with a foundation concrete thereafter after digging along a bottom contour at a predetermined distance from the cut slope. While stacking the retaining wall block for reinforcement on the foundation concrete, the work is to squeeze the backfill between the cut slope and the retaining wall block, and at every regular interval, the retaining wall block to which the lock, such as a steel rod reinforcement, is fastened, is laid, and the retaining wall block The cut slope was reinforced by filling the soil in the empty space between the cut slopes or pouring concrete to form the retaining wall.

However, the retaining wall block configured as described above has a vertical shape on the rear side, so that when the steel bar reinforcement is installed in the vertical direction on the cut slope having a constant inclination angle, the retaining wall block is installed in the vertical direction on the cut slope. The connection requires a coupler that can change the direction of the tensile force of the steel reinforcement. Therefore, as the coupler installation work is added, there is a problem that the workability is lowered and the construction cost is increased. In addition, there is a problem that it is difficult to effectively ensure the stability of the cut slope because the transfer of force from the rod reinforcement to the retaining wall block is not effective because the direction of the tensile force of the steel reinforcement is changed.

In addition, since the retaining wall block has a vertical shape in the conventional retaining wall block, the retaining wall block is to be stacked, and then the soil is filled in the empty space between the retaining wall block and the cut slope, or the concrete is poured. There was a problem improving.

In addition, in the retaining wall structure configured as described above, the vegetation of the retaining wall is difficult and the fastening portion of the steel reinforcement is exposed on the front surface of the retaining wall block, which is vulnerable to corrosion and harms the appearance.

Meanwhile, as a conventional technique, vegetation blocks for greening and vegetation of retaining walls are disclosed (Korean Patent Publication Nos. 2007-0101940 and 2007-0053922), but these vegetation blocks are upper vegetation using a stepped retaining wall structure. As is available for (growing up in part of the retaining wall), the front vegetation that causes the grass to grow throughout the front of the retaining wall is an impossible problem.

Therefore, the present invention was devised to solve the problems posed by the conventional reinforcement earth block, the object of the present invention is to simplify the installation, but to secure the stability of the slope such as cut slope effectively improve the rigidity of the retaining wall The present invention provides a vegetation reinforcement block and a retaining wall structure using the same.
