Reinforced concrete single-tower cable-stayed bridge pier tower beam consolidation construction method
The invention provides a reinforced concrete single-tower cable-stayed bridge pier tower beam consolidation construction method. The reinforced concrete single-tower cable-stayed bridge pier tower beam consolidation construction method comprises the following steps that S1, a tower column is divided into a plurality of construction areas; s2, tower column bottom foundation reinforcement and bearing platform construction are conducted; s3, four stiff skeletons are installed in the separated double-limb part, S4, the two stiff skeletons located on the same side in the bridge extending direction are connected through an arch frame, and inner cavities in the two sides of the double-limb intersection part are intersected in an inner cavity of a single tower limb; and S5, the creeping formwork conducts construction on the single tower limb in an automatic climbing mode till tower column construction is completed. The stiff skeleton is arranged, the structural strength of the bridge body is met through the stiff skeleton, the reinforcing steel bars can be supported in the construction process, the stiff skeleton is used as a reference to provide construction precision, construction can be completed in a short time, the construction period of bridge construction is shortened, and delay of the construction period is avoided.
本发明提供一种钢混独塔斜拉桥墩塔梁固结施工方法，包括以下步骤：步骤S1，将塔柱划分为多个施工区域；步骤S2，进行塔柱底部基础加固和承台施工；步骤S3，在分离双肢部内安装四个进行劲性骨架，步骤S4，位于桥梁延伸方向同侧的两个劲性骨架之间通过拱形架连接，双肢交汇部两侧的内腔交汇于单塔肢内腔；步骤S5，爬模通过自动爬升的形式对单塔肢进行施工，直至完成塔柱施工。设置劲性骨架，通过劲性骨架从而满足桥体的结构强度，在施工过程中可以对钢筋进行支撑，并利用劲性骨架作为参考提供施工精度，以此可以在较短时间内完成施工，减少了桥梁施工的施工工期，避免了工期延误。
