Concrete arch bridge vertical pile construction technology
The invention discloses a concrete arch bridge vertical pile construction technology, and relates to the technical field of building construction. Comprising the steps that construction is prepared, and the positions of vertical piles are determined; a first section of the pile hole is excavated, and a lock opening is built after the first section of the pile hole is excavated; formwork erecting and pouring are conducted on the protection arm of the first section of the pile hole, and the first section of the pile hole is formed; erecting a vertical transportation bracket at an upper opening of the pile hole; removing the formwork when the strength of the first section of retaining wall meets the design strength requirement; excavating a pile hole below the first section of pile hole; after the pile hole overall excavation operation is completed, the pile hole is checked and accepted; reinforcing steel bars are installed in the pile holes, and reinforcing steel bar net racks are formed in the pile holes; and concrete is poured into the pile hole. According to the construction method, the first section of pile hole is excavated in the position of the vertical pile firstly, the lock opening is built after the first section of pile hole is excavated, the lock opening can be firmer, construction of the lock opening is more convenient, the vertical transportation support is erected after the first section of pile hole is completed, and the structure of the vertical transportation support can be more reasonable.
本发明公开了一种混凝土拱桥竖桩施工工艺，涉及建筑施工技术领域。包括：施工准备，并对竖桩位置进行确定；开挖桩孔第一节，并在开挖桩孔第一节后砌筑锁口；对桩孔第一节的护臂进行支模和浇筑，第一节桩孔成孔；在桩孔上口架设垂直运输支架；第一节护壁强度达到设计强度的要求时拆模；开挖第一节桩孔下方的桩孔；完成桩孔整体开挖作业后，对桩孔检查验收；在桩孔内安装钢筋，并在桩孔内形成钢筋网架；在桩孔内浇筑混凝土。本发明通过先在竖桩位置开挖第一节桩孔，并在开挖第一节桩孔后砌筑锁口，可以使锁口更加牢固，更加便于对锁口进行施工，通过在完成第一节桩孔后搭设垂直运输支架，能够使得垂直运输支架的结构更加合理。
