PRECASTED RETAINING-WALL SEGMENT STRUCTURE AND PRECASTED RETAINING-WALL STRUCTURE}

The present invention relates to a prefabricated retaining wall segment structure and a prefabricated retaining wall structure. Specifically, the present invention relates to a prefabricated retaining wall segment structure and a prefabricated retaining wall structure supported by a support pile when the retaining wall is constructed.

Retaining walls are much constructed for slope reinforcement in civil engineering and construction.

Conventional retaining wall construction has proceeded by digging the slope and placing the bottom concrete, and then installed the "L" shaped reinforced concrete retaining wall structure thereon and backfilling the soil in the rear space.

In this way, the retaining wall is inevitably high when the slope is steeply inclined, and in this case, the length of the supporting portion of the "L" shaped structure in order to support the retaining wall is increased in proportion to the height so as to have sufficient supporting force.

However, it is difficult to secure the length of the supporting portion of the retaining wall structure of the "L" structure according to the site conditions, and the construction cost also increases rapidly as the retaining wall structure increases.

Meanwhile, the conventional prefabricated retaining wall forms a retaining wall structure by simply assembling the segment structure to connect the protrusion and the groove, but such a prefabricated retaining wall has difficulty in having sufficient supporting force.

In order to solve the problem of the prefabricated retaining wall, a plurality of earth anchors have been added in the horizontal direction, but the construction cost is increased because the construction must be performed over the entire wall surface of the prefabricated retaining wall.

The present invention is to solve the above problems, to provide a prefabricated retaining wall segment structure and a prefabricated retaining wall structure using the same by having a sufficient support force and easy construction by supporting vertically through the support pile to the lower ground of the retaining wall structure when building the retaining wall do.

In order to solve the above-mentioned problem, according to the first embodiment of the present invention, in the segment structure that is assembled in the vertical direction to form the retaining wall, forming a vertical wall of the retaining wall during assembly, but for supporting the vertical wall A wall portion having a first pile through hole formed at a center portion of the support pile so as to penetrate in the same direction as the vertical wall, and a coupling portion formed at both sides to engage with a wall structure of a neighboring retaining wall during assembly; And a wall support having a second pile through-hole formed so as to protrude in a horizontal direction in a bar shape at a lower center of the wall and inserted into the backfill during construction of the retaining wall, wherein the second pile is formed to vertically penetrate the second support pile. A prefabricated retaining wall segment structure comprising a is proposed.
At this time, one side of the coupling portion may be formed to engage with the other side of the coupling portion of the neighboring prefabricated retaining wall segment structure during assembly, or the coupling portion may be formed to engage with the intermediate connecting segment coupled between the other adjacent coupling portions. have.

Also, in one example, the wall support may be integrally formed with the wall portion.
