電纜橋架線路的敷設一般有四種方式:直埋電纜敷設、排管電纜敷設、電纜溝或隧道內電纜敷設、橋架電纜敷設。下面
濟南橋架廠家為您解說。
There are generally four ways to lay cable bridge lines: directly buried cable laying, pipe laying, cable laying in cable trench or tunnel, and bridge cable laying. Next, Jinan Bridge manufacturer will explain for you.
水平敷設施工要點:
Key points of horizontal laying construction:
(1)敷設方法可用人力或機械牽引,機械敷設電纜的速度不宜超過15m/min。
(1) The laying method can be manual or mechanical traction, and the speed of mechanical cable laying should not exceed 15m / min.
(2)電纜沿橋架或托盤敷設時,應單層敷設,排列整齊。不宜交叉,拐彎處應以大截面電纜允許彎曲半徑為準。
(2) When cables are laid along the bridge or tray, they shall be laid in single layer and arranged in order. It is not allowed to cross, and the allowable bending radius of large section cable shall prevail at the turning.
(3)不同等級電壓的電纜應分層敷設,橋架下方應噴涂電纜走向標示。
(3) Cables with different voltage levels shall be laid in layers, and the cable direction signs shall be painted under the bridge.
電纜垂直敷設施工要點:
Construction points for vertical cable laying:
(1)垂直敷設,有條件的好自上而下敷設。土建未拆吊車前,將電纜吊至樓層頂部。敷設時,同截面電纜應先敷設低層,后敷設高層,要特別注意,在電纜盤附近和部分樓層應采取防滑措施。
(1) It shall be laid vertically and from top to bottom if conditions permit. Before the crane is removed for civil works, the cable shall be hoisted to the top of the floor. During laying, cables with the same cross-section shall be laid on the low floor first and then on the high floor. Special attention shall be paid to taking anti-skid measures near the cable tray and on some floors.
(2)電纜自下而上敷設時,小截面電纜人力可敷設時可用滑輪大繩人力牽引敷設。高層、大截面電纜宜用機械牽引敷設。
(2) When the cable is laid from bottom to top, the cable with small cross-section can be laid manually. When the cable can be laid manually, it can be pulled and laid manually by pulley and rope. High rise and large section cables should be laid by mechanical traction.

(3)沿橋架或托盤敷設時,每層少加裝兩道卡固支架。敷設時,應放一根立即卡固一根。
(3) When laying along the bridge or tray, each layer shall be equipped with at least two clamping supports. When laying, one should be placed and one should be clamped immediately.
(4)電纜穿過樓板時,應裝套管,敷設完后應掛標識牌并用防火材料封堵嚴密。
(4) When the cable passes through the floor, it shall be installed with sleeves. After laying, it shall be hung with signboards and sealed tightly with fireproof materials.
直線段敷設施工要點:
Key points of laying in straight section:
(1)宜把電纜盤放在工井底面較高一側的工井口外邊,通過牽引鋼絲繩,將電纜牽引拖過排管引到另一個井底面較低的工井。
(1) The cable reel should be placed outside the wellhead on the higher side of the working well bottom, and the cable should be pulled through the pipe row to another working well with a lower bottom by pulling the steel wire rope.
(2)排管內電纜敷設順序原則上從下到上、從兩邊到中間逐層敷設,便于后期電纜施工。
(2) In principle, the cable laying sequence in the pipe row is from bottom to top, from both sides to the middle, layer by layer, so as to facilitate the later cable construction.
(3)余纜盤井應選擇轉角井或有中間接頭前后井盤纜,且每個井盤纜不宜超過2根。
(3) The angle well or the front and rear well with intermediate joint shall be selected for the remaining cable reeling well, and no more than 2 cables shall be reeled for each well.
In addition, it can be known that in order to facilitate the laying of the cable and reduce the friction between the cable and the pipe wall, the cable can be coated with a lubricant that does not have a chemical effect with its sheath before entering the pipe.
