Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a prefabricated retention wall segment structure and a prefabricated retention wall structure,

The present invention relates to a prefabricated retaining wall segment structure and a prefabricated retaining wall structure. More particularly, the present invention relates to a prefabricated retaining wall segment structure and a prefabricated retaining wall structure that are supported by a support pile at the time of constructing a retaining wall.

The retaining wall is being built many times for slope reinforcement in civil engineering and construction field.

Conventional retaining wall construction has been carried out in such a manner that a slope is erected, a floor concrete is laid, an "L" shaped reinforced concrete retaining wall structure is installed thereon, and the gravel is filled in the rear space.

In such a case, the retaining wall has to be raised when the slope becomes a steep slope. At this time, in order to support the retaining wall, the length of the support portion of the "L" structure should be prolonged in proportion to the height.

However, depending on the conditions of the site, it may be difficult to secure the length of the support portion of the retaining wall structure of the "L" structure. Also, as the retaining wall structure is increased, the construction cost is also rapidly increased.

Meanwhile, in the conventional assembled retaining wall, the retaining wall structure is formed by simply assembling the segment structure and connecting the projections and the grooves, but such a conventional retaining wall has difficulty in providing sufficient supporting force.

In order to solve the problem of the prefabricated retaining wall, a plurality of earth anchors have been additionally installed in the horizontal direction. However, the construction cost must be increased over the whole wall surface of the prefabricated retaining wall.
