PURPOSE: A grating for a drainage canal is provided to easily connect and arrange on a path for a drainage canal and enable easy handling, carrying and installation due to light weight and excellent strength. CONSTITUTION: A grating(10) for a drainage canal comprises a body(11), a connecting/ length adjusting unit(12), a connecting/ support unit(13), and a cover unit(14). The body comprises a lattice-type reinforcing rib and a protrusion(11b). The body is formed as a synthetic resin injection unit. The connecting/ length adjusting unit is protruded from the middle part of one external surface of the long-axis direction of the body in a state that a reinforcing member(12a) is installed. The reinforcing member provides cutting preventing and reinforcing functions. The connecting/ length adjusting unit maintains a connected state and adjusts connected length through a slide. |
