UHPC (Ultra High Performance Concrete)-coated common concrete box girder structure and construction method thereof
The invention relates to a UHPC (Ultra High Performance Concrete)-coated common concrete box girder structure which comprises a common concrete beam, the outer surface of the common concrete beam is coated with a UHPC shell, the UHPC shell is formed by splicing a plurality of UHPC shell sections which are prefabricated in sections, and every two adjacent UHPC shell sections are fixedly connected through a UHPC post-pouring section. The structure is reasonable in stress, high in strength and convenient to construct, corrosion resistance of UHPC is utilized, the problem that common concrete is corroded by the environment can be effectively avoided coastal, the structural strength of the concrete box girder is fully guaranteed, and development and popularization of a prestressed box girder construction method are facilitated.
本发明涉及一种采用UHPC外包普通混凝土箱梁结构，包括普通混凝土梁，所述普通混凝土梁的外表面包裹有UHPC外壳，所述UHPC外壳由若干个分段预制的UHPC外壳节段拼装组成，两相邻的UHPC外壳节段之间均经UHPC后浇段进行固定连接。该结构受力合理、强度高、施工便利，利用UHPC耐侵蚀性能，可有效沿海避免环境对普通混凝土的腐蚀问题，充分保证了混凝土箱梁的结构强度，有利于预应力箱梁施工方法的发展与推广。
