At 8 o 'clock on January 5, the Yangtze River estuary in Jiangsu Province was misty, and the "Second Hang Changqing" piling ship invested and built by the second Aviation Bureau of Central enterprises in Hubei was delivered and put into use. As the piling ship with the highest pile frame, the largest pile lifting capacity, the longest pile driving length and the strongest wind and wave resistance in the world, its delivery marks a new milestone for China in the field of ocean engineering equipment manufacturing.

    In Qidong City, Jiangsu Province Zhenhua Qidong sea industrial base, the reporter saw that this is a red and blue cuboid giant ship. At the stern, red and white pilings rose into the sky. Liu Xiucheng, chief engineer of the project, said the ship is 130.5 meters in length and 40.8 meters in width, with an area equivalent to 12 standard basketball courts and a pile frame up to 150 meters.

    How does a pile driver drive a giant pile into the deep sea? He pointed to the equivalent of 50 layers of pile frame, said that the three hooks and the pile holder cooperate with each other, can "hold" the maximum diameter of 7 meters of steel pipe pile. Then, the top of the frame is equipped with a hydraulic pile hammer weighing 200 tons, which transmits power through the oil pipe. Like a hammer hitting a nail, the maximum pile weight of 700 tons and more than 125 meters long steel pipe piles can be deeply embedded in the sea bed, which is a veritable "strong man".

    "In the construction of large Bridges and offshore wind power in China, it is necessary to drive many steel pipe piles into the water bottom to form pile foundations, and the pile driver is to undertake this task." Liu Xiucheng said that the piling ship is composed of three parts of the hull, pile frame and cylinder, the hull is the platform, the pile frame is the support, the cylinder is the power of the pile frame pitching, with the help of the large cylinder, the piling ship can not only play vertical pile, but also can play the inclined pile, through the bridge, but also reduce the height "lying flat".

    The operation of the cylinder can drive the Angle change of the pile frame, which plays a key role in the pile driving ship, just like the "heart" of the pile driving ship. This key component is led by the second Aviation Bureau of China Communications. It is reported that the ship's cylinder weighs 385 tons, diameter of nearly 2 meters, total length of 28 meters, weight, diameter, length are the world's first, standing up ten stories high, is the world's largest pile ship cylinder, breaking the world record.

    "We have successively developed key core technologies such as domestic sealing rings, domestic bearing lubrication pads and laser cladding corrosion resistant materials, and finally realized the localization of super large and ultra-long oil cylinders." China Transportation second aviation bureau deputy chief engineer Yang Xiuli said.

    It is understood that for a long time, the sealing ring, bearing lubrication pad, and corrosion resistant material manufacturing of large cylinders have been restricted by foreign countries, and raw material procurement is difficult and expensive. In order to break the monopoly, the second Aviation Bureau of China Communications united six domestic industry chain leading enterprises and four universities such as Tsinghua University and Tongji University to carry out technical research on cylinder machine and key components from research theory, simulation analysis and experiment.

    This is a green and low-carbon ship. Compared to traditional piling boats, this boat is more environmentally friendly and intelligent in design and use. It uses DC bus super energy storage system, through the super capacitor, energy storage battery to cut the peak and fill the valley, smooth the power grid fluctuations, with efficient permanent magnet motor as a lifting motor, more fuel efficient than ordinary fuel tanker, carbon emissions are also greatly reduced.

    The Hercules also have great wisdom. It is reported that before the piling ship is driven, the computer will automatically calculate the positioning accuracy of the pile, which can not only monitor the safety in real time, but also automatically detect the work process and generate construction reports. The pile driving operation management system attached to it can measure and control the plane and verticality of the pile, and establish a large database of related information such as geological data, pile parameters and pile driving records by automatically recording data. Not only that, the remote starfish station differential function piling positioning system installed in it can achieve centimeter-level positioning accuracy in the far-reaching sea, which is called "Dinghai treasure".

    Super large piling ship is an important support for the construction of major projects such as cross-sea passage, far-reaching sea wind power and offshore oil resources development. In the future, "Second Hang Changqing" will participate in the construction of the world's longest cross-sea high-speed railway bridge - Hangzhou Bay cross-sea railway Bridge between Nantong and Ningbo high-speed railway.

    The diamond is good for China work. With the bridge construction to the deep sea, long span march, as China's bridge construction "dream team", in addition to the "second Hang Changqing", the world's largest tower crane invested by the second aviation Bureau of China Transportation, the largest domestic lifting capacity of the double-arm variable amplitude crane has been put into production, helping China's bridge assembly, intelligent construction.
