内河流域水下钻爆设备改装与钻爆工艺探讨

Discussion on equipment modification and technology of underwater drilling blasting in inland river basin

为解决水下钻孔爆破施工的困难,根据重庆辖区内河流域水下工况特点,将普通驳船改装成专用钻爆船。阐述了钻爆船的设备改装方式和钻爆施工工艺,并在重庆港主城港区佛耳岩作业区二期港池疏浚等工程中进行了应用,取得了良好的爆破效果。为类似港口建设和航道整治工程提供了借鉴经验。

In order to solve the difficulties of underwater drilling and blasting construction,according to the characteristics of underwater working conditions in river basin under the jurisdiction of Chongqing,convert ordinary barges into dedicated drilling and blasting vessels.Explain the equipment modification method and drilling and blasting construction technology of the drilling and blasting ship,and it was applied in the project of the second phase of the harbor basin dredging in the Foeryan operation area of the main port area of Chongqing port.A good blasting effect was achieved,it provides reference experience for similar port construction and waterway improvement projects.
