Sandbeach-staying-waiting construction method of cutter suction dredger

The invention relates to a sandbeach-staying-waiting construction method of a cutter suction dredger. The sandbeach-staying-waiting construction method is characterized by including the steps that a dredger pit area without hard foreign matter is selected, and the cutter suction dredger is sailed to a soil taking area to excavate a dredger pit when the sea level meets the drafting condition; when the water depth can not meet the drafting condition, the cutter suction dredger stays on a sandbeach and is stranded to wait till the sea level rises again; after the water depth meets the requirement and the cutter suction dredger floats, excavation of the dredger pit is conducted again till the dredger pit with the depth and the area meeting requirements is excavated. Compared with the prior art, the sandbeach-staying-waiting construction method has the advantages that the time spent on entering and exiting of the dredger and pipe disassembling is saved, excavation of the dredger pit can be completed only through t
