The overall migration project of the ancient ship No. 2 of the Yangtze River Estuary entered the "fast track"!In the future, TA will settle in Yangpu!

In 2015, a relatively well -preserved iron shipbuilding was found in the waters of Chongming, archaeological number "Yangtze River Pass One". Then he found another larger and complete wooden ancient shipbuilding in the north of the shipwreck. The archeological number was "Yangtze River Entou No. 2". After salvaging the water, the ancient ship No. 2 of the Yangtze River Estuary will be relocated to the former site of Yangpu Binjiang Shanghai Shipyard to carry out archeology and protection.

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 work of the overall migration of ancient ships is successfully completed during the pre -processing stage

In March of this year, shortly after the archeology and cultural relics protection of the No. 2 ancient ships in Yangtze River, it was affected by the epidemic. The Municipal Cultural Tourism Bureau, together with the Shanghai Salvation Bureau and other departments and units of the Ministry of Transport, through the resource integration and optimization plan, under the premise of ensuring the quality and construction safety, the project is strictly and orderly to promote the resumption of projects.

On May 9, the special arc beam was restored to process. On June 1st, the main operating ship "Dali" one -click "sailing" of the main operating ship who assumed the overall migration of the Yangtze River Estuary No. 2 to leave the site of the ancient ship site and carried out the pre -processing stage.

Under the guidance of the State Administration of Cultural Relics, the Municipal Cultural and Tourism Bureau, together with the Shanghai Salvation Bureau, organizes archeological, diving, objective exploration, salvage engineering and other fields, and accurately positions Gu Gu with a combination of marine material exploration and scanning testing and diving exploration. The border and depth of the boat, reviewed 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, and design archeological relics in the sinking area of ​​the beam of the curved beam. Clean up, extract scattered cultural relics such as the rudder (rudder pole and rudder handle), iron anchor, cable, architectural materials, purple sand pots, etc. to maximize the loss of dispersing cultural relics during the overall salvage stage of the ancient ship to ensure the integrity of the information of the ancient ship.

The scattered cultural relics extracted this time (upper left: rudder (rudder pole and rudder handle); upper right: rudder (rudder pole and rudder handle), ship board, building material overlook; bottom left: "Youlan Secret" purple sand pot ; Right: Four -claw iron anchor water map)

In late June, the project completed the multi -wave bouquet of the ancient ships, which clarified the sinking position of the curved beam end plate and pre -tapped the end plate sinking ditch with 20 meters long, 1.3 to 3 meters wide, and depth of more than 3 meters. The potential obstacle was excluded for the subsequent salvage end plate.

On July 5th, at the site of the ancient ship site, the "Hercules" completed the sinking piles of the four positioning piles with high quality. After survey by the positioning personnel, the verticality of the positioning pile was less than 0.5%and the absolute position error was less than 31 cm. The degree meets the design requirements. This marks the successful completion of the overall migration and pre -processing phase of the Yangtzekou No. 2 of Changjiangkou.

The world ’s first ancient ships are fully salvaged for special engineering vessels.

The Municipal Cultural Tourism Bureau, together with the Shanghai Salvation Bureau of the Ministry of Transport, designed a new special salvage engineering ship and named the "Effective" wheel to ensure that the ancient ship No. 2 of the Yangtze River Estuary completed the overall salvage and migration.

"Effective" wheel side view

The main scale of the "struggle" wheels is 130 meters long, 34 meters wide, and a depth of 9 meters. The biggest feature is that there is a synchronous upgrade device at both ends of the ship. Moon pool of rice. 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 it to the Shanghai Shipyard No. 1 dock. Only one boat has completed the improvement of 3 ships to be completed. The three tasks of transportation and docks have greatly improved operational efficiency and ensured the safety of cultural relics during construction.

It is reported that the hull is designed for the overall salvage and migration project of the "Yangtze River Entou No. 2" ancient ship, providing new ideas for the study of the overall migration project in the future, opening new methods, and establishing a new model of overall migration technology.

The "struggle" wheel of improvement, transportation, docking, and uninstallation in one. In addition to the function of protecting the ancient ships and carrier cultural relics, there are many advantages such as high safety, strong operability, and high technology content. Discovery and cultural relics display and utilization work has a basic and critical effect.

It is understood that after the "High" is a brief rest, it will go to the end plate frame of the beam -shaped beam on the pier of Hengsha base. It is planned to be sailed to the site of the ancient ships again in mid -to -late August, and the overall salvage construction operation of the ancient ship will be officially carried out, and the ancient ships will be produced as soon as possible to solve the many puzzles contained in the ancient ships.
