Abstract

The invention discloses a longitudinal push-close construction device for steel box girder including steel box girders, the front end of the steel box girder is detachably connected with the front guide girder, the rear end of the steel box girder is detachably connected with the rear guide girder, and further comprises a guide rail fixed on the upper end surface of the left bridge, wherein the guide rail is slidably connected with one end of a pushing device, the other end of the pushing device is detachably hinged with the lower ends of the steel box girder and the rear guide girder in turn,and the front guide girder is slidably matched with a sliding support of the front guide girder fixed on the right bridge. A longitudinal push-in closure construction method for steel box gird comprises that follow steps of: 1) pushing the front guide beam to abut on the sliding support of the front guide beam for the first time; 2) that lead guide beam is slidably matched with the slide supportof the leading guide beam until the steel box beam reaches a longitudinal predetermined position; 3) adjusting the transverse position of the steel box girder; 4) installing the hoisting equipment andlowering the steel box girder to the closed position for fixing. The invention utilizes the pushing device to push the steel box girder support to realize the rapid longitudinal forward movement. Thesliding support of the leading beam can transversely adjust the transverse position of the steel box girder to realize the precise positioning of the steel box girder.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a steel box girder longitudinal pushing and closing construction device and a construction method thereof. Background technique [0002] The construction of the closing section of the steel box girder is usually carried out on the water by transport ships to transport the closing section below the design position, and then the closing section is hoisted by the bridge deck crane to realize it. However, the transport ship is greatly affected by the sea environment, and it takes a long time to move and position. Moreover, the size of the transport ship is limited, and the closing section should not be too long, resulting in a slow construction speed. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a steel box girder longitudinal pushing and closing construction device ...
