Description

[0001] Block Assembly for retaining wall [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block assembly for a retaining wall structure, more particularly, to a block assembly for a retaining wall structure having improved sound insulation and sound insulation, easy installation, and a good appearance.

The retaining wall structure is constructed to prevent the collapse of the ground such as roads, railways, industrial complexes, residential land areas, and gully lands or cutouts, and is constructed of concrete, brick, natural stone, It is a wall that prevents the earth from falling by resisting the earth pressure. It is a wall to prevent the slope of the slope or soil from falling down by the pressure of the soil.

The retaining wall structure cuts the gravel in the construction area or forms the mold with reinforcing bars and panels to fill the valleys and low areas in mountainous areas. In addition, it is common to construct concrete by pouring concrete into the mold and then filling it with gravel and crushed stone. However, the retaining wall of such reinforced concrete is not preferable in view of cost and air due to molding and curing, May not be easy to secure.

On the other hand, a block-type retaining wall is widely used, which solves the above-mentioned problems in recent years and provides aesthetically pleasing appearance.

However, in the conventional block type retaining wall structure as described above, there is a problem that the retaining walls are unstable due to the absence of a separate structure for increasing the coupling force between the retaining walls.

In the conventional retaining wall structure, the space for storing the gravel-like material has a horizontal structure with respect to the ground. Therefore, there is a problem in that the gravel-like material is likely to be washed down into roads or rivers in a rainy season and the gravel-like material inside the retaining wall structure is lost.

In addition, the retaining wall structure can be installed at an edge of a place where a noise source such as a highway exists, or in an industrial complex or a residential land formed near a public road, such as a residential area, A structure in which a separate sound absorbing material is embedded in order to maintain a comfortable living environment is required.
