Ultra-high performance concrete gate-type pier structure and construction method

The embodiment of the invention discloses an ultra-high performance concrete gate-type pier structure and a construction method, relates to the technical field of bridges, solves the problem that a conventional gate-type pier structure cannot be applied to spanning an existing line in operation, reduces the construction cost, and saves the construction period. The ultra-high performance concrete gate-type pier structure comprises a plurality of pier columns and a plurality of cover beams, and the pier columns are erected on a foundation; the capping beam is arranged at the upper ends of the pier columns and connected with the pier columns, the capping beam is used for bearing a bridge floor, the capping beam is made of ultra-high performance concrete, and a cavity is formed in the capping beam. The ultrahigh-performance concrete gate-type pier structure is used for supporting a bridge floor. 本申请实施例公开了一种超高性能混凝土的门式墩结构及施工方法，涉及桥梁技术领域，解决了常规门式墩结构无法运用在跨越正运营的既有线问题的同时降低了工程造价，节省施工周期。该超高性能混凝土的门式墩结构包括墩柱和盖梁，其中，墩柱竖立在地基上，数量
