On April 10th, China's first ultra-large 1900 kJ double-acting full-hydraulic offshore piling hammer successfully completed the piling test at the Tianjin Binhai Heavy Equipment Reloading Base. The success of this test marked that Taizhong Group had filled our country’s The gap in the technical field of super-large hydraulic hammers has broken the long-term monopoly of similar foreign products, and has a milestone significance in further improving China's marine industrial equipment capabilities and improving China's marine resources development capabilities.
The hydraulic hammer is a kind of engineering equipment that uses hydraulic energy as the driving force and uses hammer hammering pile principle to perform offshore pile foundation construction. Its role is to push steel piles up to more than 80 meters into the bottom of the continental shelf in the early stage of construction, like The single root bar plays the role of 'Dinghai Pins' to ensure the safe and smooth follow-up operations. With the deepening implementation of the National Ocean Rejuvenating and 'One Belt and One Road' initiative, development of offshore wind power and deep sea minerals, exploitation of oil and gas resources The demand for large-sized hydraulic hammers is one of the main equipments in the world's marine resources development and construction market. Prior to this, China could only adopt imported methods to purchase such equipment.
The 1900 kJ double-acting hydraulic piling hammer independently developed by Taizhong Group has a self-weight of about 430 tons and a total height of 22 meters. It is mainly composed of a hammer body, a hydraulic power station and an electric control part. The piling diameter is 3-6.5 meters. The energy generated by the blow reaches 1900 kJ, which is equivalent to the energy generated by a 200 ton weight free fall 1.5 m to the foundation. It is mainly used for the construction of large-scale offshore pile foundations, and is also applied in the domestic 5MW offshore wind power installation and construction process. The matching hammer type. Compared with foreign products, it has the advantages of easy operation, efficient operation and environmental protection, low cost, etc. After testing and testing the performance parameters are close to the international advanced level.
Taizhong Group adhered to the drive of innovation and succeeded in making China’s first super-large hydraulic hammer to stand proudly at the Taihai Binhai base. This is another major result of independent innovation and it is another major breakthrough in manufacturing in Shanxi Province. At present, Taizhong Group is actively developing 3,000 kJ hydraulic pile hammers, striving to achieve localization of all ultra-large hydraulic pile hammers.
