水下爆破施工技术

Underwater Blasting Technology

新建杭长铁路客运专线牌头浦阳江特大桥186-188号墩桩基承台施工采用在深水条件下进行水下爆破作业施工技术,深水基础是桥梁建设经常遇到的工程结构,地质环境条件不同也是决定开挖方法的主要参数,采用不同的施工方法决定深水基础施工质量的关键,在深水条件下,合理的开挖方式将直接影响工程的进度、质量和成本,牌头浦阳江特大桥深水基础开挖,采用水下爆破施工技术在实施过程中取得良好效果。

Underwater blasting technique is adopted for pile cap construction of Paitoupuyangjiang Super Bridge pier No.186 to 188 of newly-constructed Hang-Chang PDL.Deep water pile foundation is a frequently encountered engineering structure.Geological environmental condition is the main factor that decides excavation method which is vital to deep water foundation construction.Reasonable excavation method has a direct impact on project progress,quality and cost.Good result has been achieved by using underwater blasting technique for deep water foundation excavation of Paitoupuyangjiang Super Bridge.
