Abstract:The bridge prefabrication and culvert and overhead jack-in of railway are key points for construction of railway Overpass Bridge and culvert. The bridge and culvert jack-in is the most important thing for construction quality control of overpass bridge. Construction of bridge and culvert can be conducted by many methods, such as primary jack-in method, across jack-in method, split jack-in method and slot jack-in method. The commonly used one is primary jack-in method. The common failings for jack-in construction are as follows: overlarge deformation of rear back to cause stopping jack-in, settlement and crack of slide plate, crack of bunching tip of bridge and culvert and lateral displacement of track to influence train running. This paper describes the technical points for bridge and culvert jack-in construction in details and puts forward the technical measures for prevention and treatment of construction accident in combination with construction example. Practice shows the measures are feasible with getting good result.
