豎井濟南電纜橋架的設計特點是什么
電纜橋架就位后,即可敷設電纜。按原計劃進行。橋上敷設的纜索應有序布置。盡量避免過馬路。敷設應固定在適當?shù)木嚯x,標識應及時安裝。電纜端頭和軸的兩端應安裝標記板。標線板上應注明行號,如無,應注明電纜類型、規(guī)格及起止地址:字跡應清楚,不易跌落,規(guī)格應通用,防腐、懸掛應牢固。
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.
電纜穿過豎井后,用防火枕將電纜密封。規(guī)劃施工時預埋在樓層底部的預埋件用于防火隔斷的固定,防火隔斷為4mm厚鋼板?;鹫眍^有三種規(guī)格,在此期間我輸入32 o x 120 x 25日Ⅱ類型是160 * 120 * 25,Ⅲ類型是160 * 75 * 25,根據(jù)預留孔和橋梁標準,選擇火枕頭類型。將火枕放置在防火隔墻上時,應整齊地放置在電纜旁邊,使火枕與電纜之間的間隙不應超過1cm,火枕厚度不應小于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.
在電纜橋的兩端和連接處應留出一段備用長度。電纜進入豎井、線圈、管道時,應關閉出入口,管道密封。如果電纜橋架敷設在有麻鞘的軸上,應將麻鞘剝離,保留護甲。施工前,電纜橋架應清洗、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. If the cable tray is laid on the shaft with hemp sheath, the hemp sheath shall be stripped and the armor shall be kept. Before construction, the cable tray shall be cleaned and sealed.
