Construction method and coating process of urban rail dual-purpose double-layer large-span steel truss
The invention discloses an urban rail dual-purpose double-layer large-span steel truss construction method and a coating process, and belongs to the field of municipal bridge engineering, and the urban rail dual-purpose double-layer large-span steel truss construction method comprises the following steps that S1, underground pipelines in a construction area are changed and moved, ground roads are broken and removed, and surveying personnel conduct surveying and setting out on a foundation pit part; the foundation pit is constructed by combining two modes of slope excavation and cast-in-place pile support excavation; s2, a required steel structure is produced and manufactured while the foundation pit is constructed, and the steel structure is subjected to coating protection and segmented transportation and storage; the walking track of the gantry crane is transversely and slidably spliced, compared with a spliced steel armature, the weight is lighter, thrust of a hydraulic cylinder needing to be used is small, the walking track is simple in structure, the probability of errors generated during splicing is small, due to the fact that the walking track is simple in structure, after splicing errors occur, the walking track is convenient to adjust, and the splicing efficiency is improved. The steel armature can be prevented from being adjusted, and the steel armature is prevented from being damaged.
本发明公开了一种城轨两用双层大跨度钢桁架施工方法及涂装工艺，属于市政桥梁工程领域，包括以下步骤：S1：对施工区域地下管线进行改迁、地面道路破除，测量人员对基坑部位进行测量放线，并采用放坡开挖加灌注桩支护开挖两种方式组合进行基坑施工；S2：在基坑施工的同时生产制造所需的钢结构，并对钢结构进行涂装防护和分段运输存放；将龙门吊的行走轨道横向滑移拼接，相较于拼接后的钢衔架其重量更轻，需要使用的液压缸的推力较小，且行走轨道的结构简单，拼装时发生误差的概率较小，且由于行走轨道结构简单，在发生拼接误差后，便于对行走轨道进行调整，能够避免对钢衔架进行调节，避免钢衔架受损。
