Construction method for clay bow blowing of trailing suction dredger
The invention belongs to the field of water conservancy projects, and particularly relates to a construction method for clay bow blowing of a trailing suction dredger. Calculating process parameters such as critical flow velocity, pipeline friction loss and optimal concentration by using a bow blowing effect calculation model, bow blowing calculation analysis software, key flow velocity calculation software and the like of the large drag suction dredger, measuring and calculating conveying efficiency, and determining a sludge pump rotating speed combination scheme; 2, loading the sand, the clay, the sand, the clay and the sand into a cabin according to a sequence of'sand-clay-sand '; thirdly, according to bow blowing construction efficiency of different blowing distances measured and calculated in the construction preparation stage, a proper dredge pump rotating speed combination is selected; 4, controlling the flow velocity and the concentration in a recommended process parameter range for measurement and calculation in the bow blowing process; fifthly, flushing in the cabin is conducted through cooperation of the deck part and the dredging platform, and the dredging platform uses a flushing system to flush the cabin according to system data and the situation reported by the deck part; and 6, the small-particle clay and silty-fine sand mixture is blown out through a mud pump.
本发明属于水利工程领域，具体的说是一种耙吸船黏土艏吹的施工方法，第一步：根据工程根据管线布置方案、耙吸船泥泵特性，使用大型耙吸船艏吹功效计算模型、艏吹计算分析软件、关键流速计算软件等计算临界流速、管线摩阻损失、最佳浓度等工艺参数，测算输送效率，确定泥泵转速组合方案；第二步：按“砂→黏土→砂→黏土→砂”的顺序装舱；第三步：根据施工准备阶段测算不同吹距的艏吹施工效率，选择合适的泥泵转速组合；第四步：艏吹过程中控制流速、浓度在测算推荐的工艺参数范围内；第五步：舱内冲水由甲板部配合挖泥台进行，挖泥台根据系统数据及甲板部所汇报情况，使用冲水系统进行冲舱；第六步：小颗粒的黏土以及粉细砂混合物由泥泵吹出。
