Abstract
In response to the requirements of intelligent construction in high-speed railway engineering,an intelligent cantilever bridge building machine for continuous beam construction has been developed to improve the automation,intelligence,rapidity and safety level of suspended continuous beams(rigid structures)in high-speed railways,and overcome the shortcomings of traditional hanging basket structures such as poor stability,low intelligence level,high installation and dismantling risks,and difficult construction accuracy control.This paper provides a detailed introduction to the six major system fixtures,including the load-bearing system,formwork system,hydraulic system,intelligent system,protection system,and walking(backward)system of the cantilever bridge building machine,as well as the six major process technologies of assembly,preloading,walking,pouring,backward,and dismantling.Compared with the traditional hanging basket tooling,this paper analyzes the progressiveness and superiority of the cantilever bridge building machine in technology,in order to provide technical reference for the better promotion of the new bridge tooling equipment.
