| 摘 要： | 杭州湾跨海大桥大口径超长钢管桩(Φ1.6 m,长8.9 m)长期处在泥下区、海水区、浪溅区和大气区的腐蚀环境中,其腐蚀环境和防护要求不同。较为系统地介绍了应用于这3个不同区域的3种不同特点和性能的高性能改性熔融结合环氧粉末涂料性能和特点,并在预制现场通过特殊的涂装工艺,一次性将这3种高性能粉末涂料涂敷在钢桩的不同防腐部位,预制出了高性能的防护钢桩。

| Abstract: | Sea-crossing bridge piles works in various marine environments,such as splash zone,subsea water and muddy seabed.Corrosion is often a principal determiner of the designed expectancy of the piles.The triple layer construction of coating has been recently developed for the sea-crossing Hangzhou Bay bridge piles.All three layers are simultaneously fusion bonded together to form unique construction of coating on steel pipe.The newly developed method is advantageous in many respects over the existing usual practices in corrosion protection of the bridge. |

| Keywords: | steel piles anti-corrosion fusion bonded epoxy multi-layer coatings |
