Construction method applied to ultra-high performance concrete-common concrete U-beam bridge
The invention discloses a construction method applied to an ultra-high performance concrete-common concrete U-beam bridge. The U-shaped beam bridge comprises an ultra-high performance concrete U-shaped beam and a common concrete panel, and the two parts are guaranteed to work together at the joint through a retarder scabbling method. UHPCU-shaped beams are prefabricated on the U-beam bridge, in the prefabrication process, a rough surface is formed on the upper surface of the U-beam bridge by coating a retarder in cooperation with flushing of a high-pressure water gun, and then the U-beam bridge is assembled on site for pouring of a common concrete bridge floor. According to the construction method, the performance of the concrete material can be fully exerted, and the construction method has the advantages of being rapid and convenient to construct, low in construction cost, good in stress performance and the like.
本发明公开了一种应用于超高性能混凝土‑普通混凝土U梁桥的施工方法。该U梁桥包括超高性能混凝土U形梁、普通混凝土面板两部分，所述两部分在连接处通过缓凝剂凿毛方法保证共同工作。U梁桥先进行UHPCU形梁的预制，预制过程中通过涂刷缓凝剂配合高压水枪冲洗使其上表面形成粗糙面，再到现场拼装进行普通混凝土桥面的浇筑。该施工方法使得混凝土材料性能能得到充分的发挥，且具有施工快速便捷、建造成本少、受力性能好等优点。
