Shipwreck salvage is a risky, time-consuming, and expensive process. Although there are many sunken ships along coastlines and in the open seas, the salvage process of a sunken ship has rarely been reported. The integrated salvage of the “Yangtze R

Abstract With the continuous construction of urban traffic roads, more and more new roads are cut off by existing roads to form “dead end roads”. There is an urgent need for a trenchless method suitable for urban ultra-shallow overburden to build

As an important part of the integral salvage “Yangtze River Estuary II”, several curved beam sections had to be jacked through the soil around the wreck to form a bottom bracket to wrap the wreck. The curved beam sections are different in structu
