After the dredger is in place, the steel pile positioning cross excavation construction method is used for dredging and hydraulic filling construction. This is a construction method in which the main positioning pile falling on the median line of the groove is used as the rotation center of the hull, and the reamer swings laterally back and forth from left to right within the width of the groove through transverse action, so as to make the reamer cut the soil layer of the excavation section in layers.

Adjust the speed and stop of the left and right traverse winches, retracting and releasing traverse cables to change the moving speed of the reamer and different cutting positions of the reamer on the cross section. Then, the mud water mixture is sucked by the mud pump and transported to the designated hydraulic filling area through the sludge discharge pipeline. According to the requirements of the designed River and lake dredging area, the dredger uses dredging and other mechanical equipment to excavate, and hydraulically transport the dredged spoil to the back water side of the embankment through the sludge discharge pipeline, which is combined with pond filling and pressure leaching; It not only helps to expand the flood discharge section, but also helps to prevent damage to the foundation pipeline. It has been widely used in river and lake dredging projects.
