Floating towing erection method of bridge
The invention discloses a floating towing erection method for a bridge, and belongs to the technical field of bridge construction. The method comprises the steps: arranging pushing equipment and a slideway at the abutment position of a lakeshore, and arranging a sliding block on the slideway; assembling an integral beam with a plurality of internodes above the slideway; installing a lifting supporting frame capable of lifting in a vertical direction on a tugboat, moving the tugboat to a first preset position in the lake, and fixing the tugboat; enabling the integral beam to fall on the slidingblock, and pushing the integral beam to the opposite bank by using pushing equipment; when the integral beam crosses the tugboat, lifting the lifting support frame, and fixedly connecting the liftingsupport frame with the integral beam; and removing the limitation on the tugboat, and controlling the tugboat to drive the integral beam to advance towards the lakeshore on the slideway until the integral beam reaches the target position. Before floating dragging is conducted, the sliding block on the slideway and the lifting supporting frame on the tugboat are used for conducting one-time systemconversion on the suspended integral beam to be erected, the construction safety and reliability are improved, and the bridge line shape is easy to control.
本申请公开一种桥梁的浮拖架设方法，桥梁施工技术领域，包括：在湖岸的桥台位置设置顶推设备、滑道，并在滑道上设置滑块；在滑道的上方拼装具有多个节间的整体梁；在拖船上安装可沿竖直方向升降的升降支撑架，移动拖船至湖内的第一预设位置，并固定拖船；将整体梁下落在滑块上，并使用顶推设备将整体梁向对岸顶推；当整体梁越过拖船时，上升升降支撑架，并将升降支撑架和整体梁固接；解除对拖船的限制，并控制拖船带动整体梁在滑道上向湖岸前进，直至整体梁达到目标位置。本申请在进行浮拖之前，使用滑道上的滑块和拖船上的升降支撑架对悬设的待架设的整体梁进行一次体系转换，提高施工安全可靠性，且易于控制桥梁线形。
