The present invention relates to a reinforced soil retaining wall block having a reinforced support structure with excellent seismic performance to stably support the retaining wall even in the event of an earthquake and a collapse prevention effect, and a construction method thereof.

In general, a retaining wall is a structure that prevents its collapse by supporting the soil on the rear surface by being installed on various slopes or vertical surfaces of an incision formed by civil works, such as roadside slopes, embankments, river banks, and landscape walls. It is constructed in consideration of the factors applied to the retaining wall.

Such a retaining wall cuts the soil and sand of the construction area, and after constructing a form with reinforced bars and panels, pouring concrete into the form and curing it, and reinforcing soil including soil, crushed stone or rubble on the back of the reinforced concrete. It is common to be built by filling.

In the case of such a reinforced concrete retaining wall, the resistance moment generated by its own weight against the soil at the bottom of the retaining wall is increased rather than the overturning moment that attempts to overturn the vertical wall of the retaining wall. By having a supporting structure, there is an advantage that a separate anchor means for supporting the retaining wall is not required.

However, since these reinforced concrete retaining walls are not desirable due to the enormous cost and time required for construction in molding, curing, excavation, and embankment, as well as aesthetic problems, most retaining walls are constructed in a beautiful appearance by retaining wall blocks. Retaining walls are being widely constructed.

Retaining walls constructed by the retaining wall blocks are generally prefabricated, stacking several tiers in the transverse direction, and then filled with reinforcement soil on the back surface, and the retaining wall constructed by these retaining wall blocks is conducted by horizontal earth pressure. Various support methods are employed to prevent the point from collapsing due to the moment, and among these support methods, the resistor anchor method is mostly constructed.

That is, the resistor anchoring method fixes the front end of a bar material such as reinforcing bar, steel bar, or FRP bar to the retaining wall block, and fixes the rear end of the bar to a concrete resistor embedded in the reinforced soil. It is a method of supporting the retaining wall by the frictional force of the bar.

Looking at the technology for building a retaining wall block using the conventional resistor anchor method, each tip is connected to the retaining wall block to support the retaining wall block in Korean Patent Registration 10-0467244 (registration date January 11, 2005) and arranged side by side on the left and right sides.

It is formed in a shape, and the ring portions corresponding to each other overlap each other so as to communicate up and down, and each vertical bent portion of the digut-shaped connecting member is inserted into the overlapped ring portions, and is embedded in the reinforcing soil filled in the back of the retaining wall in a vertical anchor structure.
