Railway culvert extension structure construction method
The invention discloses a construction method of a railway culvert lengthening structure, and belongs to the technical field of bridge and culvert construction. According to the construction method of the railway culvert lengthening structure, the railway culvert lengthening structure comprises an existing box culvert, an existing splayed wing wall and a box culvert lengthening section, a cutting part formed through cutting is arranged on the inner side of the end, connected with the existing box culvert, of the existing splayed wing wall, and the end, connected with the existing box culvert, of the box culvert lengthening section is located in the cutting part; the box culvert extension section, the existing box culvert and the existing splayed wing wall are poured into a whole by adopting a cast-in-place concrete construction method; the construction method comprises the following steps: cutting the inner side of one end, connected with the existing box culvert, of the existing splayed wing wall by adopting a wire saw method; and the box culvert body of the box culvert lengthening section is constructed in a segmented mode through a cast-in-place method. The method is simple in construction, high in construction efficiency, safe in construction and low in construction cost, the existing splayed wing walls can be used for protecting the roadbeds on the two sides of the culvert during box culvert extension construction, and instability of the roadbeds on the two sides of the culvert in the culvert extension construction can be prevented.
本发明公开了一种铁路涵洞接长结构施工方法，属于桥涵施工技术领域。一种铁路涵洞接长结构施工方法，铁路涵洞接长结构包括既有箱涵、既有八字形翼墙、箱涵接长段，既有八字形翼墙与既有箱涵连接的一端的内侧具有通过切割形成的切割部，箱涵接长段与既有箱涵连接的一端位于所述切割部内，箱涵接长段采用现浇混凝土施工方法与既有箱涵及既有八字形翼墙浇筑为一体；施工步骤包括：采用绳锯法对既有八字形翼墙与既有箱涵连接的一端的内侧进行切割；采用现浇法分段施工箱涵接长段的箱涵涵身。本发明施工简单，施工效率高，施工安全，施工成本低，箱涵接长施工时可利用既有八字形翼墙对涵洞两侧的路基进行防护，可防止涵洞接长施工中涵洞两侧路基失稳。
