A water collecting unit of a bridge is provided to facilitate the control of its installation height by using a height-adjusting unit including bolts and flanges. A water collecting unit of a bridge comprises a lower tank(4), an upper tank(2), and a height-adjusting unit. The lower tank is fixed to the predetermined height of a form. The upper tank shapes to a funnel, including an inlet(10) on which a grating(8) is mounted, and an outlet(12) which is fit the top part of the lower tank. The height-adjusting unit assembles the upper tank to the lower tank, including a first flange(16), a lower flange(20), and bolts(22). The first flange is integrated with the lower tank is provided with bolt holes(14) circumferentially. The second flange is attached to the outer surface of the upper tank perpendicularly, and provided with bolt holes(18) circumferentially. The bolts adjust the interval between the upper and lower flanges by driving into the bolt holes of the lower and upper flanges. |
