摘要
以栾川至卢氏高速公路LLTJ-1标两河口互通立交D匝道桥为例,对小半径曲线桥预制梁不同的架梁方法优缺点进行了分析,从架桥机的参数设置、过孔、旋转以及预制梁的运输、架设等方面介绍了双导梁架桥机架梁施工方法,达到了缩短施工周期、降低施工成本、提高作业安全性等效果。
Taking the D ramp bridge of Lianghekou Interchange in LLTJ-1 of Luanchuan-Lushi Expressway as an example,this paper analyzes the advantages and disadvantages of different beam erection methods for precast beams of small radius curved bridges,and introduces the beam erection construction method of double guide beam bridge erecting machine from the parameter setting,perforation,rotation of the bridge erecting machine,as well as the transportation and installation of prefabricated beams.Which has achieved the effects of shortening construction period,reducing construction cost and improving operation safety.
