Construction Safety Management Strategy for Yaotian Road across the Railway Bridge Section
A series of construction technology and safety management measures are proposed for the complex construction environment and safety management requirements of Yaotian Road Bridge over railway.Based on the structural characteristics and geological condi-tions of the bridge,rotary drilling technology,automated steel box girder lifting and symmetrical balanced pouring of the merging section are adopted to optimize the precision control of pile foundation construction and steel box girder lifting,with the verticality error of the pile foundation being controlled within±1%,and that of the steel box girder lifting being controlled within±2 mm.At the same time,a real-time monitoring system and risk assessment model were established to comprehensively assess the safety risks of overhead work and large-scale equipment operation,forming an effective prevention and control mechanism,reducing the construction risks,and fur-ther improving the technical level and safety of the construction of the cross-line railroad bridge section.
