In view of the technical problems of softening of foundation soil and reduction of bearing capacity of the breakwater under the action of repeated wave loads during the execution of the second phase of the deepwater waterway regulation project in the Changjiang Estuary,Tianjin Port Construction Corporation has successfully developed safer,higher quality and highly efficient technology and special-purpose marine craft and machinery for laying deepwater sand blankets and offshore installation of prefabricated drains,which were more suitable for the working conditions in the Changjiang Estuary,and has also explored the construction technology for prefabrication of caissons with rubber anti-sliding plates,to ensure the efficient implementation of the engineering measures against softening of foundation soils.
