自航耙吸挖泥船浅水施工加装艏冲装置施工技术与应用

Construction technology and application of dredging in shallow areas with high-pressure water jet and suction system mounted on self-propelled trailing suction hopper dredger

浅区疏浚一直是内河航道维护疏浚的难题。当内河航道水深不能满足自航耙吸船空载施工吃水要求时,耙吸船将无法进行上线下耙疏浚施工。为了解决该问题,将最新研制的艏冲装置系统安装于耙吸船船艏,并利用艏冲装舱施工方法成功解决了浅区疏浚的难题,取得了良好的经济效益和社会效益。

Dredging in shallow area has always been a knot in the maintenance dredging of inland river waterways. It is impossible for a trailing suction hopper dredge to sail to the dredge cut and execute dredging operation when the channel depth of inland rivers can＇ t meet the requirements of unloaded draft of a self-propelled trailing suction hopper dredger. A newly developed high-pressure water jet and suction system installed in the stem of trailer has successfully solved this problem and achieved good economic and social benefits.
