Recently, the "Changjiangkou No. 2" ancient ship's overall salvage and migration project main operating ship "Hercules" departed from the Pockest Terminal, set sail to the scene of the ancient ship site of the "Changjiangkou No. 2". Open sea construction.

The ancient ship of "Yangtze River Estuary 2" is a wooden sailing boat during the Tongzhi period of the Qing Dynasty. It is the largest, most complete, and huge number of cultural relics found in underwater archeology in my country. On July 6, after completing the overall salvage and migration project of the ancient ship, the "Yangtze River Hits 2" ancient ship's overall salvage and relocation project team composed of Shanghai Cultural and Tourism Bureau and Transportation Department of Shanghai Preliminary preparations for salvage at sea. This time the ancient ship salvage and migration project uses the world's first "arc beam non -contact cultural relics overall migration technology". When operating at sea at sea, the "Hercules" will delay 22 giant arc beams around the ancient ships, forming a huge huge The semi -cylindrical box wraps the ancient ships and its attached thick sediment and seawater. Therefore, the overall assembly of the end plate -longitudinal beam framework is the focus of the preparation of the early stage. The end plate -the longitudinal beam frame is connected by 22 arc beams to form a semicircular base of 48 meters long and 19 meters wide. Its assembly accuracy will directly affect the sea -shaped beams of the sea. For the smooth progress of the construction of the maritime scene, the project team carried out the overall land assembly of the end plate -longitudinal beam framework. After more than 50 days of fighting, the final two end boards and 4 long beams were assembled. At the same time, the preparation work such as the debugging of the end plate sinking auxiliary device, the assembly of the transmitting frame, the pipeline connection debugging, the control room sensor regulation, the pile tube welding, and the installation of the beam.

This time the "Hill No." went to sea again, marking the core link of the "Yangtze River Hits 2" ancient ship archeology and cultural relics protection projects -the overall salvage and migration project of ancient ships was officially launched. It is getting closer and closer to the "life life" of the ancient ship.

The entire operation time of the "Higher" is expected to cost 2 to 3 months, and then the "struggle" wheel of a dedicated salvage engineering ship will simultaneously increase the water outlet with a total weight of more than 10,000 tons. In the middle of the "Fighting" wheel.

In order to ensure that the ancient ships could salvage water and safely to reach the "new home", the project team of the Shanghai Salvation Bureau innovatively designed and built a "struggle" wheel of special project vessels opened in the middle of the middle. The ship is equipped with a 46 set of hydraulic pressure improvement systems. By simultaneously enhance technology, the box that wraps the ancient ship is entered into the central opening, and then transported directly through the sea. Essence At present, the former site of Yangpu Shanghai Shipyard has been selected as the "new home" after the ancient ships of the "Yangtze River Estuary No. 2".

During the early underwater survey and overall migration pre -processing stage, some ancient ship -related water relics have been extracted and cleaned up. In the recent pre -processing stage, the rudder and iron anchor were found in the north of the ancient ship. Among them, the iron anchor is a four -claw anchor, with a length of 3.3 meters (excluding iron ring). It is currently a larger ancient four -claw iron anchor found in China. In addition, most of the 600 pieces of water out of the water that have been cleaned are mostly produced from Jingdezhen. Among them, 60 cm of bean -green ground pile of white blue and white Panasonic Gaosu double -ear bottle hidden in 50 pieces of well -made blue and white dumplings.

After the ancient ship is salvaged, the archeological staff of the cultural relics will be carried out in a full range of research on the formation of the ancient ship site, construction technology, and routes according to the archeological and cultural relics protection schemes of the ancient ships. A lot of puzzles.
