公铁两用架桥机移运架T形梁施工工效及资源消耗研究

预制T梁架设有跨墩龙门吊机、扒杆、铁路架桥机、公铁两用架桥机等多种方式。结合施工现场地形和现有施工设备、桥型等条件,选择最适宜工程项目特点的运架梁方式,对安全、优质、高效建设桥梁至关重要。此文通过分析轮胎式运梁车配合公铁两用架桥机移运架铁路T梁现场测定和实际施工统计资料,对32 m单线T梁移梁、运梁、架梁作业程序和工效及资源消耗进行研究,编制出公铁两用架桥机安拆、调试及移、运、架预制T梁参考定额,对铁路定额的修订和补充以及工程造价人员编制概预算具有一定参考价值。

Construction Efficiency and Resource Consumption Research of Moving and Erecting T Beams by Dual Purpose Bridge Girder Erection Machine

Prefabricated T beams erection has a variety of ways. Combined with the construction site terrain and existing construction equipment, bridge pattern and other conditions, it is very important to choose the most suitable gantry crane beam mode according to project characteristic for safely, high - quality and efficiently erecting bridge. Through the analysis of field measurement and statistical data, the operation procedures and resource consumption of moving, transporting and erecting 32 m single T beam are studied. The reference quota of moving, transporting and erecting T beams by dual purpose bridge girder erection machine is compiled. It has certain reference for engineering budget for cost personnel. revising and supplement of railway quota and compiling
