Since the cups are not connected to the plate, the weight is reduced and the material cost is reduced. The present invention relates to a drainage plate and a drainage plate forming method capable of increasing the value of the product since the color of the sheet can be adopted in various ways.

In general, the drainage plate is placed between the foundation concrete layer and the floor layer of the construction site, and serves as a drain passage for collecting water into the drain so that water penetrated into the foundation concrete layer does not flow into the floor layer.

In the conventional drainage plate, a plurality of cups are arranged vertically and horizontally, and the upper portions of these cups are integrally injection molded in a mold such that the cups are connected to a plate made of the same material. The conventional drainage plate connected to a plate is laid horizontally and horizontally on the foundation concrete layer, and when the concrete for bottom layer formation is poured thereon, concrete enters into the cup and is cured, and then a drain passage is formed between the cup and the cup at the bottom of the drainage plate.

However, the conventional drainage plate has a disadvantage in that it costs a lot of material costs because it connects the cup to the plate shape when ejected from the mold. In addition, since the product is produced only in black because recycled plastic is used, there is a disadvantage that the aesthetics are reduced. In addition, the drainage plate used in the construction site has a disadvantage that can not be used as a landscape drainage plate because its use is limited.
