In view of the shortage of sand source in the construction of sand-filled bags,we study the barge loading technology of the trailing suction hopper dredger by bow blowing taking the southeast breakwater project of Jingtang Port as an example,and combining with another dredging project using TSHD,and propose creatively to change the traditional sucking ship to the construction method of the bucking construction using the newly developed offshore loading and unloading platform to carry out the barge loading operation.The technology aims to make full use of the natural resources on site to ensure that the project is completed on time based on the principle of cost saving and environmental protection.At present,there is no mature construction technology for TSHD in our country.The successful implementation of this technology has referential significance for similar projects.
