Abstract
The present invention discloses a large tonnage entire hole box beam for transporting and a method for construction, and comprises the transportation of the box beam and the erecting of the box beam. The transportation construction of the box beam mainly comprises the steps of beam transportation preparation, beam loading, beam transportation etc., and the erecting of the box beam comprises the erection of the bridge vertical over hole, beam feeding and beam hoisting for vertical shift. The method effectively solves a plurality of construction problems that the auxiliary operation time of the prior transportation construction and the prior erecting construction is long, the auxiliary equipment is more, the variable cross-beam erection and the parallel operation are not available, etc., and thus the present invention proposes a scientific construction method with short auxiliary operation time, less auxiliary equipment, and capability of parallel operation; meanwhile, the method can meet the variable cross-beam erection of a front hole beam and a tail hole beam. The method has high construction efficiency, convenient shift among the bridges and strong adaptability, and the present invention is not only suitable for the construction of the outsize bridge having a plurality of consecutive holes, but also can be well adapted to the bridge group construction with middle size and small size bridges dispersed in a bridge which only has a few box beams.
