深海急流域薄盘礁的炸礁施工技术

Reef Blasting Construction Technology of Thin Plate Reef in Deep Sea Rapids

在涡流、深急流复杂海域条件下,采用漂浮式炸礁船对薄盘礁进行炸礁施工非常困难。根据深急流深海域薄盘礁的特点,分析了现阶段炸礁通用技术及薄盘礁施工技术难点,采用漂浮式炸礁船候潮作业,增大船舶锚机吨位和六锚系统进行船舶定位方法的优势及爆破技术措施等内容,提出了在类似环境下采用漂浮式炸礁船的一种炸礁施工技术,实践证明所设计的方案及相应施工技术合理有效,对类似工程的设计与施工具有借鉴意义。

Under the condition of complex sea area of eddy current and deep jet,it is very difficult to use floating reef exploding ship to blow up thin reef.According to the characteristics of thin reef in deep jet sea area,the general technology of reef blasting and the technical difficulties of thin reef construction at the present stage are analyzed,and the floating reef exploding ship is adopted to wait for tide.In this paper,the advantages of ship positioning method by increasing the tonnage of ship anchor and six anchor system and blasting technical measures are put forward,which is a kind of reef blasting construction technology of floating reef blasting ship in similar environment.The practice shows that the designed scheme and the corresponding construction technology are reasonable and effective,which can be used for reference to the design and construction of similar projects.
