| description | 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 ca |
