The invention discloses a bridge structure accumulated dragging and pushing construction mechanism and a construction method thereof. The mechanism comprises a temporary pier supporting system which is installed in the longitudinal direction of a bridge and spans two sides of a main pier of the bridge; a slideway beam which is arranged on the main pier and the temporary pier supporting system in the longitudinal direction of the bridge; a continuous traction assembly which comprises a dragging jack, a jack reaction frame, an inhaul cable and a sliding block, wherein the dragging jack is fixedly installed at the front end of the slideway beam in the longitudinal direction of the bridge through the jack reaction frame, and the sliding block is arranged on the slideway beam in a sliding modeand connected to the moving end of the dragging jack through the inhaul cable; a vertical pushing assembly which is used for vertically pushing the bridge and is mounted on the slideway beam and the temporary pier supporting system; and a plurality of base plates which are arranged between the main pier and the bridge in a cushioning manner after the bridge is dragged and pushed in place. The problems of long cushion block transferring time, high labor cost, high risk and the like in the incremental launching construction of the bridge with the continuously changed bottom surface gradient aresolved.
Description
technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a bridge structure accumulative dragging and pushing construction mechanism and a construction method thereof. Background technique [0002] Under the environment of rapid development, the application of long-span bridge structures is becoming more and more extensive. Due to the large span, heavy weight and limited construction site in the mid-span position of the structure, especially across rivers and expressways, waterway operation and vehicle traffic Bring great difficulty to the construction. However, it is difficult to control the reaction force of each jack in the common bridge overall jacking construction, the construction progress is slow, the risk is high, and the construction cost is high. And for bridges with varying slopes at the bottom of the bridge, a large number of personnel are required to adjust the lower pads during the jacking construction operati...
