设备安装主要指风机、空调机组、风管、风阀、消声器的安装；主变压器及GIS安装、高低压成套配电柜、配电箱、控制箱、电缆电线敷设、灯具开关插座安装及其他设备安装；水管和阀门的安装；接触轨(接触网)铺设；机房标识、吊架、防火封堵等。并完成各设备的单机调试、单系统调试和综合联调。车站装修工程主要施工项目包括：砌体结构工程、抹灰工程；地板、门窗、天花板工程；装饰板(砖)、收尾工程等特殊部位，如卫生间装修工程、赛道区域顶部侧墙黑化等。在地下施工中，由于空间狭小、空间有限、视线受阻、地下空气潮湿、流通不畅，以及专业众多、工期紧、施工期间物料存放不安全、施工人员分布密度大等诸多不利因素的影响，容易发生人身伤害、触电、火灾等安全事故。

Equipment installation mainly refers to the installation of fans, air conditioning units, air ducts, air valves, and silencers; Installation of main transformers and GIS, high and low voltage complete distribution cabinets, distribution boxes, control boxes, cable and wire laying, installation of lighting switch sockets, and other equipment installation; Installation of water pipes and valves; Laying of contact rail (contact network); Machine room identification, hangers, fire blocking, etc. And complete the single machine debugging, single system debugging, and comprehensive joint debugging of each equipment. The main construction items of station decoration works include: masonry structural engineering and plastering works; Floor, door and window, ceiling engineering; Special parts such as decorative panels (bricks) and finishing works, such as bathroom decoration works and blackening of the top side walls of the track area. In underground construction, due to narrow space, limited space, obstructed vision, humid underground air, poor circulation, as well as various unfavorable factors such as numerous specialties, tight construction period, unsafe material storage during construction, and high distribution density of construction personnel, safety accidents such as personal injury, electric shock, and fire are prone to occur.

Equipment installation mainly refers to the installation of fans, air conditioning units, air ducts, air valves and silencers; Main transformer and GIS installation, complete sets of high and low voltage distribution cabinets, distribution boxes, control boxes, cable and wire laying, lamp switch socket installation and other equipment installation; Installation of water pipes and valves; Laying of contact rail (catenary); Computer room identification, hanger, fire prevention and sealing, etc. And complete the single machine debugging, single system debugging and comprehensive joint debugging of each equipment. The main construction projects of the station decoration project include: masonry structure engineering and plastering engineering; Floor, doors and windows, ceiling engineering; Decorative boards (bricks), finishing works and other special parts, such as toilet decoration works, blackening of side walls at the top of the track area, etc. In underground construction, personal injury, electric shock, fire and other safety accidents are easy to occur due to the influence of many unfavorable factors such as narrow space, limited space, blocked sight, humid underground air, poor circulation, numerous specialties, tight construction period, unsafe storage of materials during construction and large distribution density of construction personnel.
