Construction method for lower tower column of main pier of cable-stayed bridge
The invention discloses a construction method for a lower tower column of a main pier of a cable-stayed bridge in the technical field of cable-stayed bridge construction. The construction method for the lower tower column of the main pier of the cable-stayed bridge comprises the following steps that construction preparation is conducted, specifically, materials such as formworks, frame bodies, small machine tools and steel bars used for pier body construction are vertically transported through a crane; the construction method comprises the steps that a stiff framework is installed, specifically, the stiff framework is installed for 3.2 m for the first time, then one section is installed each time, the concrete pouring height of each section is equal to that of the tower column of the section, and before follow-up framework installation, measurement control points are firstly set out at four corner points of the top face of the framework of the front section. When the cooling pipe is welded in the structure composed of the reinforcing steel bars and concrete is poured, warm water or cold water is injected into the cooling pipe through the water pump and the pipeline to preserve heat of the concrete, the situation that the quality of the concrete is affected by the temperature of the external environment can be effectively avoided, and the pouring quality of the lower tower column is guaranteed.
本发明公开了斜拉桥建造技术领域的一种斜拉桥主墩下塔柱施工方法，该斜拉桥主墩下塔柱施工方法包括如下步骤：施工准备：墩身施工所用模板、架体、小型机具及钢筋等材料通过吊车进行垂直运输；劲性骨架安装：劲性骨架第一次安装3.2m，以后每次安装1节，每节同该节段塔柱混凝土浇筑高度，在后续骨架安装前，先在前节骨架顶面四个角点放出测量控制点，该种斜拉桥主墩下塔柱施工方法，在钢筋绑扎完成后，在由钢筋组成的结构的内部焊接冷却管，浇筑混凝土时，通过水泵和管道向冷却管内注入温水或者凉水，对混凝土进行保温，能够有效的避免因外部环境的温度影响混凝土的质量，保障了下塔柱的浇筑质量。
