The trailing suction hopper dredger（TSHD）that has different characteristics of the ship type is affected by wind，current and swells. Its wiring and the rake head will be changed from time to time to directly reduce the excavation quality and dredging the shallow point. Taking the phase I project of the deep-water channel in the southern area of Shijiu Port，Rizhao Port，we improve the equipments，carry out the effect analysis of different construction methods adopted for different shallow points，and summarize a set of dredging shallow point construction technology for TSHD. The results show that improving rake teeth，vertical plate，and making plough can effectively solve the problem of low dredge shallow point efficiency of TSHD，and be popularized and used in the similar projects.
