BAR CONNECTING APPARATUS FOR CONSTRUCTION OF REINFORCED SOIL RETAINING WALL}

The present invention relates to a connecting device capable of reliably connecting and fixing the horizontal bars connecting the retaining wall blocks to each other and the connecting bars connecting the horizontal bars to the cutting surface when installing the reinforced soil retaining wall.

In general, a retaining wall refers to a structure that resists earth pressure and prevents the earth from collapsing, and is defined as a wall that suppresses material on one side of the wall to maintain a difference in elevation. Surrounding slopes, roads, railroad slopes, buildings, and stepped walls all represent potential loads on the retaining wall. Retaining walls are mainly classified into three types: gravity type, cantilever type, and reinforced soil retaining wall. "Gravity retaining wall" is a form of retaining wall without reinforced soil that withstands the load of soil confined by the weight of the blocks themselves. In the case of gravity retaining walls, construction costs are higher because each block is composed of concrete or masonry blocks. The gravity retaining wall relies on the weight of the structure to withstand earth pressure.

Excavation of the soil behind the retaining wall does not affect the structural strength of the retaining wall. Cantilevered retaining walls typically have the structure of piles poured into the soil, and gain support from the resistance to rotation of the piles under the supported soil. The cantilever retaining wall has a horizontal base section buried underneath the backfill, and the backfill soil has a stem section that is permanently connected to the base to form a wall and extends vertically. The cantilevered retaining wall relies on the weight of the backfill at the base to prevent the wall from tilting.

The condition that the retaining wall must have is that it must be able to withstand the upper structure and earth pressure sufficiently, and it must have good durability, easy securing of materials, and simple construction.A widely used axle generally meets these requirements, but earth pressure and water pressure Reinforced concrete retaining walls with excellent stability and durability have been replaced when constructing important structures due to their poor resistance to resistance.

In the case of the above concrete retaining wall, it is currently the most commonly used structure, but the lack of professional skilled workers in the construction market and the resulting increase in labor costs, difficulty in quality control of cast-in-place concrete, structural weakness and construction cost when the height of the retaining wall increases. Many problems such as rising were exposed.

The present invention relates to a horizontal bar connecting a plurality of retaining wall blocks horizontally when installing a reinforced soil retaining wall, and a connecting bar connecting and fixing the horizontal bar to the surface layer (cut surface) of the soil to be reinforced, and the connection between the horizontal bar and the connecting bar The reinforced soil retaining wall installation bar connection device is designed to increase the stability of the retaining wall by firmly securing the position and fixing of multiple retaining wall blocks despite the weight of backfilling soil or cut surface filled in the part where the connection bar is installed by being firmly fixed and maintained.
