竖井济南电缆桥架的设计特点是什么
电缆桥架就位后，即可敷设电缆。按原计划进行。桥上敷设的缆索应有序布置。尽量避免过马路。敷设应固定在适当的距离，标识应及时安装。电缆端头和轴的两端应安装标记板。标线板上应注明行号，如无，应注明电缆类型、规格及起止地址:字迹应清楚，不易跌落，规格应通用，防腐、悬挂应牢固。
After the cable tray is in place, the cable can be laid. According to the original plan. Cables laid on the bridge shall be arranged in order. Try to avoid crossing the road. The laying shall be fixed at a proper distance and the signs shall be installed in time. Marking plates shall be installed at both ends of cable ends and shafts. The line number shall be indicated on the marking board. If not, the cable type, specification and starting and ending address shall be indicated: the handwriting shall be clear, not easy to fall, the specification shall be universal, and the anti-corrosion and hanging shall be firm.
电缆穿过竖井后，用防火枕将电缆密封。规划施工时预埋在楼层底部的预埋件用于防火隔断的固定，防火隔断为4mm厚钢板。火枕头有三种规格,在此期间我输入32 o x 120 x 25日Ⅱ类型是160 * 120 * 25,Ⅲ类型是160 * 75 * 25,根据预留孔和桥梁标准,选择火枕头类型。将火枕放置在防火隔墙上时，应整齐地放置在电缆旁边，使火枕与电缆之间的间隙不应超过1cm，火枕厚度不应小于24cm。
After the cable passes through the shaft, the cable shall be sealed with a fireproof pillow. The embedded parts embedded at the bottom of the floor during the planning and construction are used to fix the fire partition, which is 4mm thick steel plate. There are three specifications of fire pillow. During this period, I input 32 o x 120 x 25 days, type II is 160 * 120 * 25, type III is 160 * 75 * 25. According to the standard of reserved holes and bridges, I choose the type of fire pillow. When the fire pillow is placed on the fire partition wall, it shall be placed next to the cable neatly, so that the gap between the fire pillow and the cable shall not exceed 1cm, and the thickness of the fire pillow shall not be less than 24cm.
在电缆桥的两端和连接处应留出一段备用长度。电缆进入竖井、线圈、管道时，应关闭出入口，管道密封。如果电缆桥架敷设在有麻鞘的轴上，应将麻鞘剥离，保留护甲。施工前，电缆桥架应清洗、密封。
A spare length shall be reserved at both ends of the cable bridge and at the connection. When the cable enters the shaft, coil and pipeline, the access shall be closed and the pipeline shall be sealed.
