大型绞吸船开挖深水航道艉吹装驳工艺

为避免破坏疏浚区水环境，采用大型绞吸船在不炸礁的情况下开挖深水航道岩石，已成为现实。绞吸船通常需对接排泥管线以便将疏浚土吹填成陆域，而在航道中使用绞吸船挖岩在无适合吹距的吹填区时，可采用直接装驳和艉吹装驳两种施工工艺。重点阐述大型绞吸船开挖航道岩石疏浚土处理的新方法，移动艉吹装驳工艺的产生、实施过程的优化改进，并从中梳理、提炼、总结出绞吸船艉吹装驳的输送原理，供类似工程施工借鉴以至推广。

Stern blow loading barge process for large cutter suction dredger in deepwater channel

The large cutter suction dredger is employed to excavate deepwater channel rock without reef so as to avoid the damage of dredging to the environment. Cutter suction dredgers are usually needed to butt the mud pipeline so as to fill the dredged soil into land. When there is no suitable reclaimed area for blowing distance in deepwater channel, two kinds of construction technologies including the direct loading barge and stern blow loading barge can be used. This paper introduces a new excavated approach to excavate the dredged soil with channel rock by the large cutter suction dredger and discusses the generation and implementation process optimization of mobile stern blow loading barge, from which the conveying principle would be combed, refined and summarized, to serve as reference for and be popularized in similar projects.
