Railroad bridge replaceable rockfall protection shed tunnel and construction method thereof
The invention relates to a railroad bridge replaceable rockfall protection shed tunnel and a construction method thereof. The railroad bridge replaceable rockfall protection shed tunnel comprises multiple independent shed tunnel sections in the bridge direction, and each section is an independent single shed tunnel; and the single shed tunnel comprises a plurality of arc-shaped hollow pipe piecesat the top, vertical stand columns on the two sides and connecting plates below the stand columns, every two adjacent components are connected with each other, and the inner sides of the connecting plates extend into the lower portions of wing plates of the railway box girder and are connected with the wing plates. Main stress components are made of ultra-high-performance concrete materials, the durability of the main stress components is far higher than that of common concrete and steel, and the service life of the main stress components meets the 100-year requirement of a main structure; andmain components can normally serve after being locally maintained or replaced after being damaged, and the full-life-cycle design technology is achieved.
本发明涉及铁路桥梁可更换式落石防护棚洞及其施工方法，所述铁路桥梁可更换式落石防护棚洞顺桥向包括多榀独立的棚洞节段，每个节段为独立的一个单榀棚洞；所述单榀棚洞包括顶部多片弧形的空心管片、两侧竖直的立柱以及立柱下方的连接板，各相邻构件彼此连接，连接板内侧伸入铁路箱梁翼板下方并与其连接。本发明主要受力构件采用超高性能混凝土材料，其耐久性能远高于普通混凝土和钢材，使用寿命满足主体结构100年的要求；主要构件在损伤后能够通过局部维修或更换后正常服役，实现了全寿命周期设计技术。
