Rapid closure method for deck type steel tube arch bridge arch ribs
The invention discloses a deck type steel tube arch bridge arch rib rapid closure method which comprises the steps that S1, a time period with the lowest and relatively constant air temperature in one day is selected, and rib plates, lining tubes and flange plates are welded in multiple arch rib sections respectively; s2, a plurality of arch rib sections are hoisted, and meanwhile, a plurality of abutting devices are arranged to abut against closure devices arranged on the arch rib sections with preset pressure, so that the closure devices enter a first state; s3, a plurality of locking devices are arranged between the flange plates of the opposite arch rib sections, so that the closure device enters a second state; and S4, the abutting device is removed, and a circular hole is formed in the geometric center of the flange plate. The method provided by the invention can realize rapid closure and high precision, and can ensure that the project is completed within 3: 00-6: 00 in the morning.
本公开揭示了一种上承式钢管拱桥拱肋快速合龙方法，该方法包括：S1，选择一天中气温最低且相对恒定的时段，在多个拱肋节段内分别焊接肋板、内衬管和法兰盘；S2，吊装多个拱肋节段，同时设置用多个抵顶装置以预设压力抵顶多个拱肋节段上设置的合龙装置，以使合龙装置进入第一状态；S3，在相对的拱肋节段的法兰盘之间，设置多个锁定装置，以使合龙装置进入第二状态；S4，移除所述抵顶装置，并在所述法兰盘的几何中心开设圆孔。本发明提供的方法，可以合龙迅速，且精确度高，能够确保项目在凌晨3：00～6：00内完成。
