Extra-large bridge continuous beam closure locking method
The invention relates to a closure locking method for continuous beams of an extra-large bridge, which comprises the following steps of: constructing a side span closure section: preparing for construction: removing construction materials on a box top and in a box, measuring the height difference between a top plate and a bottom plate of a box beam at two adjacent ends of the closure section by a measurer, controlling the elevation of the end part of the closure section, and ensuring that the height difference at the two ends is not greater than 10mm; the balance of the two sides of a T structure must be guaranteed in the side span closure section construction process, closure locking setting is conducted, specifically, the closure cantilever end is temporarily connected with a side span equal-height cast-in-place section, closure section locking is conducted at the lowest temperature at night and the temperature is relatively stable, closure section stiff framework locking related embedded steel plates are embedded when a linear section and the last section are constructed, and the closure section stiff framework locking related embedded steel plates are embedded when the linear section and the last section are constructed. Concrete pouring is conducted, specifically, closure section concrete is poured when the temperature is low in one day, closure section steel bar binding is completed, an inner mold is installed, the inner mold and an outer side mold are reinforced through a pull rod, acceptance inspection is conducted, closure section concrete is poured, layered pouring is adopted, and pouring is completed at a time. The probability of generating cracks can be reduced.
本申请涉及一种特大桥连续梁合龙锁定方法，其包括步骤：边跨合龙段施工：施工准备：清除箱顶、箱内的施工材料，测量人员测量合龙段相邻两端箱梁顶板、底板之间的高差，控制合龙段端部标高，确保两端高差不大于10mm，在边跨合龙段施工过程中必须保证T构两侧平衡，合龙锁定设置：合龙悬臂端与边跨等高度现浇段临时连接，在夜间最低温度且温度相对稳定的时候进行合龙段锁定，合龙段劲性骨架锁定相关预埋钢板在施工直线段和最后一个节段时预埋，混凝土浇筑：合龙段混凝土选择在一天中气温较低时进行浇注，合龙段钢筋绑扎完成，安装内模，与外侧模加拉杆加固，并验收合格，浇注合龙段混凝土，采用分层浇筑，一次完成。本申请能够减少产生裂缝的概率。
