铁路工程T梁不同运架方式施工工艺及造价分析

Engineering Construction Technology and Cost Analysis for Different Transportation and Erection Ways of T Beam in Railway Project

目前,铁路建设的T型梁运输架设,一般采用"边铺边架"的施工组织方案,该方案存在架梁方向单一、工作面少的缺点。为了弥补这种单一运架方式的不足,达到增加工作面,赶工期的目的,出现了汽车吊架梁、公铁两用架桥机架梁方式。此文通过调研,阐述这2种运架梁方式的施工工序及工艺,并针对现行铁路工程定额体系中的缺项部分进行分析与补充,希望能为今后的类似工程设计施工起到借鉴作用。

At present, the transportation and erection of T beam in the railway construction generally use the ＂ paving and erecting ＂construction organization scheme. This scheme has the shortcomings of single frame beam direction and less working face. In order to make up for the inadequacy of the single transportation and erection mode and obtain the purpose of increasing working face and driving time limit, the automobile erecting beam and highway - railway dual - use bridge frame erecting appear. Through the investigation and research, the paper expounds the construction process and technology of the two kinds of transportation and erection beam mode and analyze hoped that it can provide reference for similar and supplement the short terms in the quota system. It is projects to design and construction in the future.
