To provide a bypass drainage groove capable of suppressing overflow of water to a surrounding.SOLUTION: A bypass drainage mechanism 1 comprises a box-shaped box body 2 which is installed at an intersection of a vertical drainage groove 101 formed on a slope S and a horizontal drainage groove, and is installed overlapping above the intersection, and an upstream flow path portion 30 which is connected to one end of the box body 2 and extends linearly to guide water flowing in the vertical drainage groove 101 to the box body 2. The box body 2 comprises a bottom wall 5 and a pair of outer walls erected from the bottom wall 5 and provided on both sides of a line connecting one end of the box body 2 to the other end. The spaced dimension between the pair of outer walls is formed to be larger than the width of the upstream flow path portion 30 at any position from one end to the other end of the box body 2. The upstream flow path portion 30 comprises a guide flow path portion 31 which is provided at a gentler slope than the vertical drainage groove 101, protrudes inside the box body 2, and guides the water flowing in the upstream flow path portion 30 toward the bottom wall 5.SELECTED DRAWING: Figure 1
