Abstract: An adjustable strand threading and lubricating device for prefabricated box girders includes an underframe. Multiple first spline shafts are rotatably installed between left and right side walls of the strand threading boxes. The first openings are respectively located above the first spline shafts, first sliding blocks are respectively provided and configured to slide up and down in the first openings, multiple second spline shafts is rotatably installed between two first sliding blocks, and axes of the second spline shafts are parallel to the first spline shafts. The first spline shafts and the second spline shafts are slidably provided with multiple strand threading units for threading steel strands, a lubricating unit is arranged on a front side of the strand threading units, and a bundling unit is arranged on a rear side of the strand threading units.

Abstract: A removal-facilitated anchor sealing device for box girder construction is provided and includes a base; wheels are mounted below the base; a forward direction of the wheels is designated as a front side; a main box body is arranged on a top surface of the base in a manner of sliding back and forth; an interior of the main box body is divided into anchor sealing chambers from bottom to top through separation plates; a front side of each anchor sealing chamber is opened; anchor sealing units are arranged in the anchor sealing chamber in sequence in a left-right direction; a spraying unit is arranged below the anchor sealing units; working ends of the anchor sealing units and working end of the spraying unit extend out of the anchor sealing chamber from the front side; a storage unit is arranged on a top surface of the main box body.
