Combined pier suitable for alpine region and construction method
The combined pier suitable for the alpine region comprises a pier inner core and a pier outer ring, the pier inner core is wrapped by the pier outer ring, the pier outer ring is made of ultrahigh-strength concrete, the pier inner core is formed by common concrete in a cast-in-place mode, and the pier outer ring is prefabricated in a processing plant; according to the combined bridge pier, only the outer ring of the bridge pier is made of ultrahigh-strength concrete with higher price, so that the freeze-thaw resistance requirement of the bridge pier can be met, the use amount of the ultrahigh-strength concrete can be reduced, and the engineering cost is considered; meanwhile, the bridge pier outer ring is prefabricated in a processing plant, the prefabricated and formed bridge pier outer ring is directly used as a bridge pier formwork on a construction site, and the material cost of the bridge pier formwork and the mounting and dismounting construction cost of the bridge pier formwork in traditional construction are saved.
本发明公开了一种适用于高寒地区的组合桥墩，包括桥墩内芯和桥墩外环，桥墩外环包裹桥墩内芯，桥墩外环由超高强度混凝土制成，桥墩内芯由普通混凝土现场浇注而成，桥墩外环在加工厂预制；这种组合桥墩仅在桥墩外环使用价格更高的超高强度混凝土，既能满足桥墩抗冻融的需求，也能减少超高强度混凝土的用量，兼顾工程成本；同时，桥墩外环在加工厂预制，预制成型的桥墩外环在施工现场直接用作桥墩模板，省去了传统施工中桥墩模板的材料费和桥墩模板的安装拆卸施工费。
