摘　　要：结合某高速公路增设北互通工程210 m小半径曲线桥25 m长预制T梁架设实践,对双导梁在小半径桥梁中采用拨轨道、搭设临时支2种方法完成前移转向的比较,分析双导梁架桥机在大跨径小半径曲线桥架设的可行性。重点介绍架桥机拼装、架桥机前移、喂梁、T梁安装和架桥机过孔转向等施工工艺。Based on the practice of erecting 25-meter-long precast T-beams of a 210-meter small radius curved bridge in an expressway,this paper compares the two methods of track shifting and temporary pier erection of double-guide beams in smallradius bridges,and analyzes the feasibility of erecting double-guide beam bridge erection machines in long-span and small-radius curved bridges.This paper mainly introduces the construction technology of bridge erecting machine,such as assembling,forward moving,beam feeding,T beam installation,through-hole steering of bridge erecting machine,etc.
