Abstract
A drainage grating includes a grating disposed on a drain, a moving panel disposed at an upper portion of the grating and configured to discharge water to the drain based on moving up and down according to a hydraulic pressure of water. The moving panel is configured to block introduction of foreign substances into the drain and facilitate cleaning or management of the drainage grating. The drainage grating is configured to be at least partially removed from a support installed at the drain to provide a sufficient drainage space in a rainy season or in heavy rain.
