Method for erecting parallel box girders in tunnel
The invention discloses a method for erecting parallel box girders in a tunnel. The method comprises the steps of making a bridge girder erection machine pass through the tunnel, wherein the bridge girder erection machine is conveyed to the position of the entrance of the tunnel by a girder transporting vehicle through two supports; placing the bridge girder erection machine in position, adjusting the height of the bridge girder erection machine to be matched with the height of the tunnel, making the height of a rear supporting leg, the height of a middle supporting leg and the height of a front supporting leg increase gradually, and making the surface of the bridge girder erection machine incline upwards horizontally; conducting girder feeding through the girder transporting vehicle; lifting the first box girder through the bridge girder erection machine; finishing girder feeding through the bridge girder erection machine; lowering and horizontally moving the first box girder through a front girder carrier and a rear girder carrier; taking the second box girder through the bridge girder erection machine in the same way and conducting lowering and horizontal movement of the girder; finishing girder erection. According to the method, due to the fact that the bridge girder erection machine is adopted to erect the parallel box girders in the tunnel, time is saved a lot, cost is reduced, erection of the first hole box girders with cast-in-place required in the prior art is achieved safely and smoothly, the difficulty of erecting the first hole parallel box girders in the specific tunnel-bridge connection environment is reduced, and construction safety and construction quality are guaranteed.
