Construction method of ultra-high performance concrete
The invention belongs to the technical field of building construction, and particularly relates to a construction method of ultra-high performance concrete. The invention provides a construction method of ultra-high performance concrete, which comprises the following steps of: binding reinforcing steel bars on a clean working surface to be constructed to obtain a surface to be constructed; the ultra-high-performance spraying anti-corrosion mortar and water are mixed, ultra-high-performance concrete mortar is obtained, and the slump of the ultra-high-performance concrete mortar is 180-220 mm; and spraying the ultra-high performance concrete mortar to a to-be-constructed surface through a spraying trolley provided with a matched stirrer, a spraying extrusion pump and a spraying manipulator, and maintaining. The embodiment shows that according to the construction method of the ultra-high-performance concrete, a spraying construction method is adopted, spraying construction is adopted for projects with high strength requirements for repairing and reinforcing the internal top faces of bridges, tunnels and buildings, the construction method has the advantages of being convenient and fast to construct, and the technical bottleneck that spraying construction of the ultra-high-performance concrete cannot be achieved is solved.
本发明属于建筑施工技术领域，特别涉及一种超高性能混凝土的施工方法。本发明提供了一种超高性能混凝土的施工方法，包括以下步骤：在清洁的待施工工作面上绑扎钢筋，得到待施工面；将超高性能喷涂防腐砂浆和水混合，得到超高性能混凝土砂浆，所述超高性能混凝土砂浆的坍落度为180～220mm；经设置有配套搅拌机、喷射挤压泵和喷射机械手的喷射台车，将所述超高性能混凝土砂浆喷射至待施工面，养护。实施例表明，本发明提供的超高性能混凝土的施工方法，采用喷射施工方法，对桥梁、隧道和建筑内部顶面的修补、加固要求强度高的项目采用喷射施工，具有施工方便、快捷的特点，解决了超高性能混凝土不能喷射施工的技术瓶颈。
