The invention relates to a single auxiliary pile emergency construction method for a double-steel-pile cutter suction dredger. According to the method, two auxiliary lines are symmetrically arranged in a digging groove, the distance between the two auxiliary lines can be calculated according to the conditions such as reamer footage, the ends of mooring cables on mooring winches on the two sides of the tail of a ship body are each additionally provided with a swing anchor, the mooring winches are retracted and released to achieve swing of a stern, and auxiliary piles are located on the two auxiliary lines in turn for transverse excavation. And continuous footage of the cutter suction dredger is realized. Continuous footage dredging of the cutter suction dredger can be achieved only through one auxiliary pile and the mooring winch, the cutter suction dredger is high in positioning precision and accurate in footage, ship transformation is not needed, it is guaranteed that the cutter suction dredger can conduct emergency continuous construction when the main pile and the trolley are damaged or break down, and the adaptive capacity of the cutter suction dredger to deal with special working conditions is improved. According to the method, the cutter suction dredger can still continue to construct under the emergency condition that the main pile and/or the trolley of the cutter suction dredger cannot work normally, and the problems that the interest rate is reduced during construction and the construction period is affected due to long-time shutdown of the construction ship are solved.

    本发明涉及一种双钢桩绞吸船单辅桩应急施工方法。该方法在挖槽内对称设置两条辅助线,可根据绞刀进尺等条件计算两条辅助线的间距,在船体尾部两侧系泊绞车上的系泊缆绳端部各加装一口摆动锚,借用系泊绞车收放实现船艉摆动,使辅桩轮流坐落于两条辅助线上进行横移挖掘,实现绞吸船连续进尺。本发明可仅依靠一根辅桩和系泊绞车实现绞吸船连续进尺挖泥,绞吸船定位精度高、进尺精准,无需船舶改造,保证绞吸船在主桩、台车受损或故障时可应急连续施工,提升了绞吸船应对特殊工况的适应能力。本方法在绞吸船的主桩和/或台车无法正常工作的应急情况下令绞吸挖泥船仍然能够继续施工,避免施工船舶长时间停工导致的施工时利率下降、影响工期问题。
