cable-stayed bridge steel girder long segment integral hoisting closure method and system
The invention discloses a cable-stayed bridge steel girder long segment integral hoisting closure method and system, and relates to the technical field of bridge closure construction. The method comprises the following steps of: hoisting a to-be-mounted beam segment to a to-be-mounted area between a main tower and an auxiliary pier through a hoisting device; placing one end, close to the auxiliarypier, of the to-be-mounted beam segment at an auxiliary pier side closure port through a jacking type bracket system, and placing one end, close to the main tower, of the to-be-mounted beam segment on a pier side support system at a main tower side closure port; a corner, close to the main tower side, of the to-be-mounted beam segment to be matched with the main tower side closure port for connection; adjusting the elevation of the to-be-mounted beam segment close to the auxiliary pier side to be consistent with the elevation of the auxiliary pier side closure port; and adjusting a corner, close to the auxiliary pier side closure port, of a side span beam segment to be matched with the corner of the to-be-mounted beam segment for connection. On the premise of reducing the construction cost, the included angle of the closure port is adjusted, so that the stress condition of a girder in the finished bridge stage meets the design requirement.
本发明公开了一种斜拉桥钢主梁长节段整体吊装合龙方法及系统，涉及桥梁合龙施工技术领域，该方法包括以下步骤：利用起吊装置将待安装梁段吊装至主塔与辅助墩之间的待安装区域；利用顶升式托架系统将待安装梁段靠近辅助墩的一端放置在辅助墩侧合龙口处，将待安装梁段的靠近主塔的一端放置在主塔侧合龙口处的墩旁支架系统上；调整待安装梁段靠近主塔侧的转角与主塔侧合龙口匹配后进行连接；调整待安装梁段靠近辅助墩侧的高程与辅助墩侧合龙口的高程一致；调整边跨梁段靠近辅助墩侧合龙口的转角与待安装梁段的转角匹配后进行连接。本发明在降低施工成本的前提下，调整合龙口的夹角，使得成桥阶段主梁的受力情况符合设计要求。
