“四电”接口工程主要指由站前施工单位负责施工的与站后“四电”工程有关的项目,主要包括综合接地、路基电缆槽和电缆井、接触网立柱基础、过轨设施等。结合工程实例,及站后单位接收和静态验收重点,介绍站前单位在“四电”接口工程施工过程中的技术控制重点及处理措施。 “Four Power ” interface project mainly refers to the projects that are responsible for the construction after the station construction unit is responsible for the construction of the “Four Electric ” project, including comprehensive grounding, subgrade cable trough and cable well, catenary column foundation, Rail facilities. Combined with the engineering examples and the reception and static acceptance of the units after the station, this paper introduces the key points and measures of technical control during the construction of the “Four Electric” interface project of the station units.
