车载式抛丸机工艺研究及其在港珠澳大桥钢桥面铺装工程中的应用
|
摘要
喷砂除锈是钢桥面铺装的第一道工序,也是确保钢桥面铺装质量的重要环节。依托港珠澳大桥钢桥面铺装工程,试验研究了不同工况条件对喷砂除锈质量的影响规律,对比了车载式抛丸机和手持式抛丸机的除锈效果。结果表明:丸料规格和配比、抛丸机施工工艺等对钢桥面喷砂除锈质量有显著影响,提出了车载式抛丸机喷砂除锈的最佳工艺组合。
Sand blasting and rust removal is the first process of steel bridge deck pavement,and also an important link to ensure the quality of steel bridge deck pavement. Relying on the steel deck pavement project of Hong Kong-Zhuhai-Macao Bridge,the influence of different working conditions on the quality of sandblasting and rust removal was studied experimentally,and the rust removal effects of vehicle-mounted shot blasting machine and hand-held shot blasting machine were compared. The results show that the specifications and proportions of shot ball materials and the construction technology of shot blasting machine have significant effects on the quality of sand blasting and rust removal of steel bridge deck. The optimum combination of sand blasting and rust removal technology of vehicle-mounted shot blasting machine is put forward.
