In general, the drainage cover has a structure that is simply adhered to the top of the drainage. If the drain cover is made of metal, it is likely to be stolen because of its high recycling value.

Accordingly, the applicant has filed a patent for the drainage cover of 2007 No. 39650, the structure of which is longer than the transverse width between the rear side both axial support portions 1b of the body 1a as shown in FIGS. 1A and 1B. A horizontal axis 1c having this large cross-sectional area is rolled out, and a bearing 1e having a horizontal axis hole 1d is formed at the front side, and on one side of the bearing 1e, the horizontal axis can be inserted only in the horizontal width direction. It has a structure in which the inlet 1f is formed. The drainage cover having such a structure pushes the horizontal shaft 1c into the inlet 1f in a vertically upright position, inserts it into the shaft hole 1d of the bearing 1e, and then rotates the installation.

Since the drain cover is connected to each other, there is no fear of theft, and the binding work is very easy. However, such a drainage cover can be used only in the straight section because of its structure, there was a problem that can not be installed in the curved section.

Another drainage cover that is used in the prior art as shown in Figure 2 has a basic shape of a square and is installed in close contact with the top of the drainage continuously, forming a hole (2b) on both sides of the body (2a) The assembly is made by fastening the 'U' type bolt 2c and the nut 2d with holes between the bodies.

Such a drainage cover can be installed in a curved section by using a wide 'U' bolt (2c) in a curved section, and the bend radius of the curved section with a plurality of 'U' bolts (2c) for each width dimension According to the value, 'U' type bolt (2c) is selected and installed. Therefore, it can be installed not only in the straight section but also in the curved section.
