Concrete panel for Cutting retaining wall that is Cutting retaining wall by the Concrete panel}

The present invention relates to a concrete panel for a retaining wall of a cut-out part and a cut-out retaining wall constructed thereby, in particular, forming a three-dimensional pattern on the front surface of a concrete panel for a cut-off retaining wall, and forming an inclined portion on the side surface, as well as straight, convex, concave round By making the retaining wall construction smooth and robust, it not only improves the aesthetics of the retaining wall, but also connects the H-shaped connecting pins through a plurality of coupling grooves formed on the upper and lower surfaces of the cut retaining wall retaining wall. Construction is achieved by combining drainage concrete panels for cut retaining walls and triple drainage inducing members on the back of concrete panels for cut retaining walls to easily induce drainage into perforated pipes or water collecting wells formed under the concrete panels for cut retaining walls. , It relates to a concrete panel for a retaining wall of cut-off part that improves economic efficiency and safety, and a cut-off retaining wall constructed thereby.

In general, a concrete panel is used to form a front wall among various materials for constructing a cut retaining wall.

However, since the conventional concrete panels for retaining walls are simply square and both corners are formed at right angles, when constructing the retaining walls forming concave or convex curves, the gaps are widened according to the installation angle of the adjacent concrete panels to the left and right. As well as deteriorating stability, it causes demolding of concrete panels and damage during transportation, which has a problem of reduced economic efficiency and reduced aesthetics.

In addition, conventionally, since the side surfaces of the concrete panel for retaining walls of the cut-out portion have a simple planar structure, when the retaining wall is built up, down, left, and right, the bonding force decreases when the retaining wall is built up, and there is a high risk of collapse, which may lead to safety accidents. There was an issue.

In addition, the concrete panels for retaining walls of heavy cuts must stand as a freestanding body before nailing or anchoring during construction, but because the thickness is thin, it is easily overturned even by weak wind pressure. As temporary materials are temporarily constructed and used, there is a problem that not only causes economic loss due to the extension of construction period, but also personal accidents.

In addition, since the conventional concrete panel for cut retaining wall attaches a simple non-woven fabric to the back surface, rainwater, etc. flows in when the compaction of the backfill material is insufficient. In addition to not only being erased, but also harming the aesthetics and causing a collapse accident due to the discharge of soil, there was a problem that not only caused economic loss, but also a personal accident.

In addition, the inclined portion 120 is preferably convex and concave in the form of an obtuse angle to prevent the gap from opening during construction.

Accordingly, when constructing a panel-shaped cut-out retaining wall in which the front surface of the cut-out retaining wall convexly forms, a gap is generated by the inclined portions 120 formed on the sides of each cut-out retaining wall concrete panel 100 in close contact with each other. It can be easily demolded without damage to the edge when demolding after production of the cut-off retaining wall concrete panel 100. Also, since the four sides of the cut-off retaining wall concrete panel 100 are obtuse angles, they can be damaged during transportation and transportation. Structural stability that can be prevented or minimized can be achieved while improving aesthetics.

That is, the concrete panel 100 is concrete by adding a drainage inducing member 160 in which a non-woven fabric layer, a grid layer, and a non-woven fabric layer form a triple structure on the rear surface. It is preferable to easily induce drainage with a perforated pipe (P) formed in the lower portion of the panel (100) or a water collecting well.

Accordingly, the drainage inducing member 160 reinforces the rear side of the concrete panel 100 for the retaining wall when cutting the retaining wall of the cut-out portion so that the inverted particles of the back-filling material 230 constructed are not leaked forward and at the same time the back-filling material Block the water leaking to the front of the concrete panel 100 for the retaining wall of the cut-off portion caused by insufficient compaction of the 230 and flow downward in the direction of gravity (flow: the fluid at the top flows down by the action of gravity. ), and then induce drainage to both ends of the cut wall retaining wall (city, end point) through a separate perforated pipe (P) or S-shaped bundle pipe, or by connecting it to a water collecting well in the middle or middle to induce water to not collect. By blocking the loss of (230), it is possible to improve the safety and durability by preventing the rise of the back pressure of the back surface due to water inflow.

In addition, the concrete panel 100 for the retaining wall of the cut-out portion of the front surface generated by the waste water discharged between the drainage hole formed on the front surface and the concrete panel 100 for the retaining-wall cut-off portion and the concrete panel 100 for the cut-off part retaining wall It can prevent aesthetic deterioration caused by stains and the like.
