Spanning type bailey beam bracket and construction method thereof

Abstract

The invention discloses a spanning type bailey beam bracket and a construction method thereof. The spanning type bailey beam bracket comprises bracket bases positioned on two sides of the bailey beam bracket, cross beams which are in horizontal arrangement are arranged at the tops of the bracket bases in a supporting manner, and the tops of the cross beams on two sides are fixedly connected with two longitudinal ends of a bailey beam. During implementation, after the construction of a box beam on one side is completed, the bracket is wholly put down to a bearing platform on the same side as the box beam, a railway and traversing devices are paved between the bearing platforms on two sides, the bracket is enabled to wholly glide to the bearing platform on the other side, and then on the other side, the bracket is wholly lifted to a proper position, so that the construction period is substantially shortened, the construction efficiency is greatly improved, and the economic benefits are further increased.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a span-type Bailey beam support and a construction method thereof. Background technique [0002] Most of the construction of cast-in-place box girders for approach bridges in the bridge shoal area is widened due to the ramp going underground and the clearance is insufficient. It is difficult to use mobile formwork for construction. Usually, the steel pipe piles are driven into the soil in the water, and the construction platform is laid on the steel pipe piles. , the cast-in-situ construction of the approach bridge box girder was completed on the construction platform, but due to the low clearance at the bottom of the beam, the removal of steel pipe piles after use was not used for construction, and due to the low recovery rate of steel pipe piles, the waste was large and the construction period was long , therefore, the prior art needs to be improved.
