Three-tower cable-stayed bridge midspan closure-section-free incremental launching closure construction method
The invention belongs to the technical field of bridge construction, and particularly relates to a three-tower cable-stayed bridge midspan closure-free section pushing closure construction method. According to the method, a pushing mechanism is installed, and a side tower middle-span closure gap beam section is hoisted to the closure gap, so that connection between the side tower middle-span closure gap beam section and the front beam section of the side tower middle-span closure gap beam section is completed, connection between the middle tower closure gap beam section and the front beam section of the middle tower closure gap beam section is completed, sequential connection of the side tower middle-span closure gap beam section and the middle tower closure gap beam section is completed, and main bridge closure is completed. The tower cable-stayed bridge mid-span closure-free section pushing closure is carried out, the influence of weather and time is avoided, the closure efficiency is high, and the cost is low.
本发明属于桥梁施工技术领域，具体涉及一种三塔斜拉桥中跨无合龙段顶推合龙施工方法。本发明通过安装顶推机构并将边塔中跨合龙口梁段吊装至合龙口、完成边塔中跨合龙口梁段与边塔中跨合龙口梁段前一梁段之间的连接、完成中塔合龙口梁段与中塔合龙口梁段前一梁段之间的连接、边塔中跨合龙口梁段与中塔合龙口梁段之间顺接及完成主桥合龙等步骤完成施工。本发明进行塔斜拉桥中跨无合龙段顶推合龙，不受天气、时间影响，合且龙效率高、投入成本低。
