Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete panel for a retaining wall of a cut-off portion, and a cut-away portion retaining wall constructed by the same.

More particularly, the present invention relates to a concrete panel for a cut-away portion retaining wall and a cut-off portion retaining wall formed by the same. More particularly, the present invention relates to a concrete panel for a retaining wall for a cut- So that the H-shaped connection pins are connected through the plurality of coupling grooves formed on the upper and lower surfaces of the concrete panel for the retaining wall for the retaining walls, so that the cut- The concrete panel for the cut-off part retaining wall and the drainage guide member for the triple drainage are joined to the back surface of the concrete panel for the retaining part for the retaining wall, so that the drainage can be easily guided by the pipe- , Economical efficiency and safety, and a concrete panel for a retaining wall It relates to a cut portion retaining wall.

Generally, a concrete panel is used to form the front wall among various materials for constructing the cut-off retaining wall.

However, since the conventional concrete panel for a cut-off part retaining wall is simply a square shape and both corners are formed at a right angle, when the cut-off part retaining wall is formed as a concave or convex curve, a gap is formed depending on the installation angle of the adjacent concrete panel, The stability is deteriorated, and the concrete panel is damaged during the deformation and transportation of the concrete panel.

Conventionally, since the side surface of the concrete panel for the retaining wall of the cut-off portion has a simple plan structure, when the retaining wall is constructed on the upper, lower, left, and right cut-out portions, the bonding force is lowered and the risk of collapse is large. There was a problem.

In addition, the heavy concrete panel for retaining retaining walls must stand as a self-retaining body before joining with nailing or anchors at the time of construction, but because of its thin thickness, overturning is easily caused by weak wind pressure. There is a problem that not only the economic loss due to the extension of the construction period but also the accident of human life occurs because the temporary construction is temporarily used.

In addition, since the conventional concrete panel for a cut-off part retaining wall adheres a simple nonwoven fabric to the backside, rainwater or the like flows into the concrete panel when the backfill material is insufficiently compaction, and rainwater leaks along with the soil- In addition to not being erased, it also caused a collapse of the aesthetic appearance and the collapse of the earth by the leakage of the earth, resulting in economic loss as well as human injury.
