On the basis of the following measures, the external protection of severely corroded parts and special parts is carried out with high structural durability.

　　1. 環氧涂層鋼筋

　　1. Epoxy coated reinforcement

　　在銹蝕更嚴重的現澆墩中，采用環級配筋。

　　In the most seriously corroded cast-in-place pier, ring graded reinforcement is used.

　　涂層在施工中容易變形是一個缺點。環氧樹脂鋼筋的保護機制是建立在完全隔離胸腔和腐爛的基礎上的在腐蝕介質基體上，環氧涂層的缺陷和接觸層的鑄態損傷容易導致彈性桿件的點狀腐蝕。相應的行動。建設中維護薄膜的完整性是環氧涂層鋼筋有效性的關鍵。

　　The coating is easy to deform in construction. The protection mechanism of epoxy reinforcement is based on the complete isolation of the chest and the rotten, and the defects of the epoxy coating and the as cast damage of the contact layer are easy to lead to the pitting corrosion of the elastic members. Corresponding actions. Maintaining the integrity of the membrane is the key to the effectiveness of epoxy coated steel bars.

　　根據橋梁規范，每米涂敷鋼筋的涂敷量不得超過25mm。

　　In accordance with the bridge specification, the amount of reinforcement to be coated per meter shall not exceed 25 mm.

　　2.總面積不得超過鋼筋表面積的0.1%。

　　2. The total area shall not exceed 0.1% of the reinforcement surface area.

　　制定環氧涂層鋼筋的儲存、運輸、加工、安裝等方面的詳細規定和規章制度，采取必要的措施，盡量減少對環氧涂層的損壞。破環試涂應盡快修復。修復用環試涂應使用鋼筋制造商提供的材料應在相對濕度小于85%的環境中進行。修復涂層的厚度不得小于180um。據美國媒體報道。混凝土澆筑、振動過程中可能會對膠環軟涂層的鋼材產生影響(共80%的損傷率發生在這里)

　　Formulate detailed regulations and rules and regulations on storage, transportation, processing and installation of epoxy coated reinforcement, and take necessary measures to minimize damage to epoxy coating. The damaged ring test coating shall be repaired as soon as possible. The ring test coating for repair shall be carried out in the environment with the relative humidity less than 85% using the materials provided by the reinforcement manufacturer. The thickness of repair coating shall not be less than 180um. According to American media. During the process of concrete pouring and vibration, it may affect the steel with soft coating of rubber ring (80% of the damage rate occurs here)

　　因此，在施工過程中，應在金屬振搗器上涂上塑料或橡膠，并使島群與鋼筋直接接觸，以減少準直損傷涂層。

　　Therefore, in the construction process, the metal vibrator should be coated with plastic or rubber, and the island group should be in direct contact with the reinforcement to reduce the collimation damage coating.
