A driven side ditch for drainage and a construction method thereof are provided to carry out construction easily and improve draining function and obtain safety of a slope by preventing outflow of soil. A driven side ditch for drainage(10) comprises an anchorage, a wing, a perforation, and a filter member. The anchorage(11) is pointedly formed downward at the lower end or a side wall(12) along the longitudinal direction. In the anchorage, a wedge-shaped fixation piece(11a) is formed on the upper end. The wing is horizontally extended from the top of the side wall to the outside. In the wing, a driven projection(15) is pointedly formed downward at the outside. A plurality of perforations(13) is formed along the longitudinal direction from the top of the side wall to drain seepage water in contact side between the ground and the gutter. The filter member thoroughly adheres all over the perforation in order to prevent inflow of soil through the perforation. |
