Abstract:
A structure for determining a central position of a pier (11) and a central position determination method, comprising: a ground support frame (1), the ground support frame (1) being positioned on the ground (9) to the right side of the pier (11), and a guide track (2) being arranged on the ground support frame (1) at an incline, a distance measuring device being arranged on the guide track (2); and a bridge support frame (5), the bridge support frame (5) being fixedly connected on top of a bridge deck above the ground support frame (1), and a reflecting piece (6) being fixedly connected to an upper end surface of the bridge support frame (5). The distance measuring device cooperates with the reflecting piece (6) to measure the central position of the pier (11). The distance measurement device comprises: a support end (7), the support end (7) being an inverted T-shaped structure, the guide track (2) being a groove structure matched with the the support end (7) having an inverted T-shaped structure, a fixing bolt (701) being connected to and penetrating an upper end surface of the support end (7), a bolt stem portion of the fixing bolt (701) being in contact with an end surface of the groove of the guide track (2), and the support end (7) sliding relatively on the guide track (2); a clamping end (8), the clamping end (8) being hinged on the support end (7) by means of a locking bolt (3); and a laser rangefinder (4), the laser rangefinder (4) being clamped on the clamping end (8). The central position of the pier (11) can thus be conveniently and quickly determined with precise positioning and easy operation.
