The invention aims to provide a pressure-resistant double-layer conveying pipeline. Seawater is directly adopted for filling in the process that the pipeline is installed and sinks into the seabed, the total weight in the transportation and hoisting process is reduced, and meanwhile the working procedure and cost increase caused by direct liquid filling in the production process is reduced. The pressure-resistant double-layer conveying pipeline comprises an inner pipe, an outer pipe and a bending stopping device, wherein the inner pipe is formed by splicing a plurality of inner pipe sections;the outer pipe is formed by splicing a plurality of outer pipe sections; the bending stopping device comprises an outer pipe connecting ring, an inner pipe connecting ring and a supporting body; the outer pipe is further provided with an automatic water filling valve; and the automatic water filling valve controls seawater to be automatically filled into an annular space between the inner pipe andthe outer pipe in the process that the pipeline sinks into the seabed, and therefore the pressure influence of seawater static pressure on the pipeline is relieved.
