The overall migration project of the ancient ship No. 2 in Changjiangkou entered the "fast lane"

On July 6, the main operating ship of the main operating ship of the main operating ship of the Yangtze River Hits 2 of the Yangtze River Hits 2 returned to Hong Kong after completing the pre -processing stage of the ancient ship site. On July 15th, the "struggling" wheel of the special salvage engineering ship for the overall migration of ancient ships was completed in Nantong and returned to Shanghai to deliver. The "Higher" and "hard work" rounds have arrived and returned to Hong Kong, marking that China's major underwater archeological projects -the most core ancient vessels of ancient ships and cultural relics protection of the Yangtze River Estuary No. 2 Ancient ship removal and relocation project made significant progress.

On June 1, the "Hercules" left Hong Kong to go to the ancient ship sedimentary waters of the Yangtze River Ekou No. 2 ancient ship to carry out the pre -salvage cleanup work. Under the guidance of the State Administration of Cultural Relics, the Shanghai Municipal Bureau of Cultural Relics and Shanghai Salvation Bureau organized professionals in many fields such as archeology, diving, physical exploration, and salvage engineering to accurately position the ancient ships with the combination of marine material exploration and scanning testing and diving exploration. The border and burial depth, reviewed the ancient captain about 38.1 meters and 9.9 meters wide, and confirmed the first to the south of the ship. Strictly follow the standardized underwater archeological work, design archeological cleanup of cultural relics scattered in the sinking area of ​​the head plate of the arc -shaped beam, and extract the rudder (rudder pole and rudder handle), iron anchor, cable, architectural material, purple sand Person and other scattered cultural relics avoid the loss of cultural relics during the overall salvage stage of the ancient ships to the greatest extent to ensure the integrity of the information of the ancient ships. In late June, the multi -wave bundle of the ancient ship was completed, and the sinking position of the curved beam end plate was clearly excavated in advance, which eliminated the potential obstacles for the subsequent overall salvage end plate. On July 5th, the "Dali" high -quality completion of the sinking piles of the four positioning piles. After survey by the positioning personnel, the absolute location and verticality met the design requirements.

In order to ensure the safe and complete overall salvage and migration of the ancient ships of the Yangtze River Estuary, the Shanghai Culture and Tourism Bureau, together with the Shanghai Salvation Bureau of the Ministry of Transport, designed a new special salvage engineering ship and named it the "Efforts" wheel. On March 10 this year, the "struggle" round started construction in Nantong. The main scale of the "hard work" wheels is 130 meters long, 34 meters wide, and a depth of 9 meters. The design is 6 meters. There is a synchronous improvement device at both ends of the ship. Pond. This design can directly raise the ancient ship from the bottom of the sea to the moon pool in the middle of the "hard work", and transport them to the Shanghai Shipyard No. 1 dock. Only one boat can complete 3 ships that can be completed and transported. Three tasks in the dock. The "struggle" wheel of upgrading, transportation, docking, and uninstallation in one, Yuechi opens like a pocket of "Kangaroo Mom" ​​to take care of the ancient ship's hull, genus tools and ship carrier cultural relics. The use of work has a basic and critical role, providing new ideas for the study of the overall migration project in the same type in the future, and establishing a new model of overall migration technology.

After the "strong number" returns to Hong Kong and the "hard work" round is delivered, the Shanghai Municipal Bureau of Cultural Relics will accelerate the overall salvage and migration project of the Ancient Ship No. 2 of the Yangtze River Estuary 2 under the guidance of the State Administration of Cultural Relics. It is planned to go to the scene of the ancient ship site again in mid -to -late August, and officially carry out the overall salvage construction operation of the ancient ship, let the ancient ships out of water as soon as possible, and solve the many puzzles contained in the ancient ships.
