The invention discloses a method for combining a cable-stayed
bridge deck cable unreeling manner and an air cable unreeling manner under the condition of a limited space. The method comprises the following steps: arranging a cable releasing tray under a cable
tower, enabling a stay cable to be hoisted and placed on the cable releasing tray, and ensuring a beam-end anchor cup of the stay cable to be placed in a manner that one surface of the beam-end anchor cup faces upwards; pulling out the beam-end anchor cup and placing the pulled-out beam-end anchor cup on an anchor head
cart, pulling the anchor head
cart towards the front end of a main beam away from the direction of the cable
tower for cable unreeling, and stopping pulling when the anchor head
cart is pulled to the front end of the main beam; hoisting the reeled stay cable on the cable releasing tray, turning over the hoisted stay cable in the air, and then placing the turned-over stay cable back to the cable releasing tray, so that the
tower-end anchor cup of the stay cable is placed in a manner that one surface of the tower-end anchor cup faces upwards; and performing air cable unreeling construction, wherein during the air cable unreeling, the tower-end anchor cup of the stay cable is pulled to slowly move upwards in conjunction with the rotation of the cable releasing tray simultaneously until the remaining stay cables on the cable releasing tray are completely hoisted, and a stay cable unreeling process is completed. According to the cable unreeling method disclosed by the invention, a
bridge deck cable unreeling manner and an air cable unreeling manner are combined, so that the problem that the
deck cable unreeling space is not enough is solved, the situation that the cable body is scratched is avoided, and construction safety is guaranteed.
