Steel box girder closure construction method for pier tower girder consolidation system
The invention discloses a closure construction method for steel box girders of a pier tower girder consolidation system. The closure construction method is characterized in that a construction process comprises the steps of girder section installation, crane movement, stay cable tensioning, closure gap observation, closure section matching and cutting, transportation positioning and hoisting, single-side welding, elevation adjustment of a loose hoisting point, proper temperature opposite pulling, closure gap welding and temporary component and crane removal. The construction process comprises the steps of girder section installation, crane movement, stay cable tensioning, closure gap observation, closure section matching and cutting, transportation positioning and hoisting, single-side welding, elevation adjustment of a loose hoisting point, proper temperature opposite pulling, closure gap welding and temporary component and crane removal. According to the method, on the premise that the closure quality and safety of the steel box girder are guaranteed, the problem that the closure temperature is lower than the designed closure temperature is well solved, the construction efficiency is high, and economic benefits and social benefits are obvious; and after implementation, each index meets the design and specification requirements.
本发明公开了一种墩塔梁固结体系钢箱梁合龙施工方法，其特征在于：施工工艺包括梁段安装、吊机移动、斜拉索张拉、合龙口观测、合龙段配切、运输定位吊装、单侧焊接、松吊点调整高程、适合温度对拉、合龙口焊接、拆除临时构件及吊机；本方法在保障钢箱梁合龙质量、安全的前提下，很好地解决了合龙温度低于设计合龙温度的问题，施工效率快，经济效益和社会效益明显；实施后各项指标均满足设计及规范要求。
