Curve variable cross-section concrete tower column of extradosed cable-stayed bridge and construction method thereof
The invention relates to an extradosed cable-stayed bridge curve variable cross-section concrete tower column and a construction method thereof. The extradosed cable-stayed bridge curve variable cross-section concrete tower column is characterized in that a tower column support system is provided Arranging an adjustable temporary diagonal bracing frame; the tower column closure section adopts an adjustable assembly type unloading device; and the stiff skeleton sections of the tower column adopt a quick connection technology. The construction method comprises the main construction steps of (1) tower column support arrangement, (2) stiff framework construction, (3) tower column steel bar binding, (4) tower column formwork engineering, (5) tower column concrete construction, (6) tower column temporary horizontal inner support construction and (7) tower column closure section construction. The extradosed cable-stayed bridge variable cross-section arched tower column is high in construction speed and high in construction quality, can effectively reduce the cost when being applied to practice, and can obtain better technical and economic benefits.
本发明涉及矮塔斜拉桥曲线变截面混凝土塔柱及其施工方法，其特征在于塔柱支架体系设置组合式连接横杆；设置可调临时对撑架；塔柱合龙段采用可调组拼式卸落装置；塔柱劲性骨架节段采用快速连接技术。其主要施工步骤包括：(1)塔柱支架布置，(2)劲性骨架施工，(3)塔柱钢筋绑扎，(4)塔柱模板工程，(5)塔柱混凝土施工，(6)塔柱临时水平内撑施工，(7)塔柱合龙段施工。本发明矮塔斜拉桥变截面拱形塔柱施工速度快、施工质量高，应用于实际可有效降低成本，可取得较好的技术经济效益。
