Bridge high pier rollover synchronous construction method
The invention provides a bridge high pier rollover synchronous construction method which is characterized by comprising the following steps that a, during rollover construction of a double-pier-body construction section, a formwork is formed by adopting a front face formwork (3) and a side face formwork (5), b, when the pier body is turned over and constructed to a section (1 ') below the tie beam, a corresponding steel bar hole is reserved in the inner side die, c, section concrete (1') below the tie beam is poured, d, an alloy steel bar is inserted into the reserved corresponding copper bar hole, e, a double-spliced I-shaped steel cross beam (14) and an I-shaped steel longitudinal beam (15) are laid on the alloy steel bar; f, the lower second-layer formwork of the beam bottom formwork is turned over and dismantled; and g, pier body concrete is poured. the construction method has the advantages that the pier rollover tie beam is used for construction, the existing formwork is fully used, the formwork is good in attachment degree, safe and reliable, the pier rollover tie beam is used for construction, iron parts do not need to be embedded in the pier body, material consumption is reduced, damage to the appearance of the pier body is avoided, later repair is avoided, and detaching is easy and assembling and disassembling are simple and convenient.
一种桥梁高墩翻模同步建造方法，其特征在于包括以下步骤：a、在双墩身施工段翻模施工时，采用正面模(3)及侧面模(5)形成模板，b、墩身翻模施工至系梁下的一个节段(1’)时，在内侧模设置预留相应钢棒孔洞，c、浇筑所述梁下的节段砼(1’)，d、在预留相应的铜棒孔洞内插入合金钢棒，e、合金钢棒上铺设双拼工字钢横梁(14)、工字钢纵梁(15)，f、将梁底模下二层翻模拆除，g、浇筑墩身砼。本发明具有利用桥墩翻模系梁施工，充分利用既有模板，模板贴合度好、安全可靠，用桥墩翻模系梁施工，不用对墩身预埋铁件，减少了材料消耗，避免对墩身外观造成破坏和后期修补，卸落简易和安拆简单方便的优点。
