橋架鋪設好后，會定期進行維修保養橋架，但由于鋪設環境太特殊，橋架腐蝕太嚴重，那么有必要拆除老化的產品。如何進行安全的拆裝工作，需要注意以下幾個方面。

After the bridge is laid, it will be repaired and maintained regularly. However, due to the special laying environment and serious corrosion of the bridge, it is necessary to remove the aged products. How to carry out safe disassembly and assembly work requires attention to the following aspects.

在拆除橋架之前，應在施工前公開施工技術，讓員工了解如何拆除，了解現場的安全隱患，增加安全防護。施工前需要與項目負責人確認設備已準備好進行拆卸，并非常注意設備接地線的斷開。施工前，檢查標志是否齊全。如果不完整，需要補充收費。施工過程中，注意保存圖片和圖片，以備日后項目反饋。所有電纜建議用專用工具拆除，不得直接剪斷。

Before removing the bridge, the construction technology shall be disclosed before construction, so that employees can understand how to remove it, understand the potential safety hazards on site, and increase safety protection. Before construction, confirm with the project leader that the equipment is ready for disassembly, and pay special attention to the disconnection of equipment grounding wire. Before construction, check whether the signs are complete. If it is incomplete, additional charges are required. During construction, pay attention to the preservation of pictures and pictures for future project feedback. All cables must be removed with special tools and shall not be cut directly.

需要熟悉環境，了解電控的操作位置和設備。拆卸設備時，建議清楚斷電狀態，并接好接地線，方可操作。其次，做好拆遷現場的安全防護和防觸電措施。然后，拆橋時要注意安全帶的位置，不能系在橋和橋的支撐上。正確、熟練地使用現場工程機械，了解其性能。在拆解過程中操作過程中，嚴格遵守防火防爆規定。

It is necessary to be familiar with the environment and understand the operation position and equipment of electric control. When disassembling the equipment, the power-off state must be clear and the grounding wire must be connected before operation. Secondly, safety protection and electric shock prevention measures shall be taken at the demolition site. Then, pay attention to the position of the safety belt when removing the bridge, and do not tie it to the bridge and its support. Correctly and skillfully use site construction machinery to understand its performance. During disassembly and operation, strictly observe fire and explosion prevention regulations.

使用明火作業時，建議采取防火措施，并有專人看守。嚴禁在易燃易爆物品周圍使用明火作業。固定的為避免交叉作業，高空作業建議系好安全帶，懸掛式安全帶建議符合安全規程要求，并有專人看管。除了交通維護，晚上在工作時間內，還應提供足夠亮度的照明和安保人員。

When working with open fire, fire prevention measures must be taken and special personnel shall be assigned to guard. It is strictly prohibited to use open fire around inflammables and explosives. Fixed in order to avoid cross operation, the safety belt must be fastened for high-altitude operation, and the hanging safety belt must meet the requirements of safety regulations and be watched by a specially assigned person. In addition to traffic maintenance, sufficient lighting and security personnel shall be provided during working hours at night.

有時還需要根據起重作業設備的重量選擇吊車或起重設備來承受重錨點應設置牢固，并做好起重安全防護工作。之后，現場配備專職安全檢查員，及時檢查和排除不安全因素。

Sometimes it is necessary to select a crane or lifting equipment to bear the heavy load according to the weight of the lifting equipment. The anchor point shall be set firmly and the lifting safety protection shall be done well. After that, the site shall be equipped with full-time safety inspectors to timely check and eliminate unsafe factors.

濟南電纜橋架老化產品拆除過程應由承包商和業主記錄并確認。此外，除銹防腐要求除銹、焊渣、毛刺、污垢和原有的弱漆膜。附著力強的原漆可以保留，但新漆的原則應與原漆在顏色上相同或至少相近。有時涂兩層底漆和兩層涂滿全身。涂漆時，讓薄膜完全干燥，然后再涂下一層。每層膜厚應為30-40um，涂層應均勻無滲漏。

The removal process of Jinan cable tray aging products shall be recorded and confirmed by the contractor and the owner. In addition, derusting and anti-corrosion require derusting, welding slag, burr, dirt and the original weak paint film. The original paint with strong adhesion can be retained, but the new paint shall be the same or at least similar in color to the original paint. Sometimes two coats of primer and two coats are applied to the whole body. When painting, allow the film to dry completely before applying the next layer. The film thickness of each layer shall be 30-40um, and the coating shall be uniform without leakage.

除了拆遷工程要注意的事項外，還要落實文明施工，及時清理和運輸垃圾，使工程竣工后施工現場干凈整潔。所有電氣設備應業主積出色協商溝通。業主與乙方人員共同確認并監督工作，確保拆遷工作順利進行。在橋架老化和拆除過程中注意以上幾點，以確保人身安全，提高工作效率。但是，在使用的時候還是要注意橋架的保養和維護。

In addition to the matters needing attention in the demolition project, civilized construction shall be implemented, and garbage shall be cleaned and transported in time to make the construction site clean and tidy after the completion of the project. All electrical equipment shall be actively negotiated and communicated with the owner. The owner and Party B's personnel shall jointly confirm and supervise the work to ensure the smooth progress of the demolition work. Pay attention to the above points in the process of bridge aging and removal to ensure personal safety and improve work efficiency. However, pay attention to the maintenance of the bridge when using it.
