中文The Binjiang surface operation platform of the East China Sea faces the sea area of the operation area. A huge piling ship comes into view, and the H450MF double-acting hydraulic piling hammer stands in the air, which is particularly dazzling. As a high-performance double-acting hydraulic piling hammer independently developed and manufactured by SEMW, H450MF is good at pile foundation construction such as deep-water port terminals, building bridges and cross-sea bridge projects. It can be said to be a "hexagonal warrior".
The sea is sparkling and the blue waves are rippling
This is the Binjiang surface operation platform of the East China Sea
SEMW H450MF double-acting hydraulic piling hammer is heroic
Accompanied by the sound of hammering on the scene
Raise the hammer, drop the hammer, penetrate
Tamp the foundation for the 150,000-ton special berth for national-level projects!
Facing the sea area of the operation area, a huge piling ship came into view, and the H450MF double-acting hydraulic piling hammer stood in the air, which was particularly dazzling. As a high-performance double-acting hydraulic piling hammer independently developed and manufactured by SEMW, H450MF is good at pile foundation construction such as deep-water port terminals, building bridges and cross-sea bridge projects, and can be said to be a true "hexagonal warrior".
Recently, as the Hanggongzhuan 801 ship drove the first steel pipe pile to the design elevation, the wharf project of the Shanghai LNG Front Expansion Project officially started. The wharf construction project will build a new 150,000-ton dedicated berth with a designed throughput of 6 million tons/year. It is expected to be able to accommodate 150,000 to 180,000 cubic meters of LNG transport ships. The construction of the project is of great significance. The wharf project adopts a butterfly layout, consisting of a working platform, a main approach bridge, a torch platform, 6 berthing piers and 6 mooring piers, etc. The total construction period of the project is 596 days.
According to the staff of Yangshan Port Maritime Safety Administration, the construction site of the project is located in the shallow waters between the existing LNG terminal and oil storage and transportation terminal on both sides. The construction waters are narrow and close to the main navigation channel of Yangshan Deepwater Port with a complex navigation environment. The construction project also involves pile-driving ships, crane ships and material transport ships with different routes and long voyages. The construction is difficult and the safety risks are high.
Faced with the difficulties of complex and dense pile foundations, poor hydrological conditions in the construction area, and tight construction schedule, the construction project team selected the country's only fully revolving multifunctional piling vessel, Hanggong Pile 801, and cooperated with Shanggong Machinery's H450MF double-force hydraulic pile hammer for simultaneous construction, helping the project's pile foundation work to proceed smoothly.
The strata in the seabed area of the SEMW H450MF double-acting hydraulic pile hammer reached a strongly weathered surface. The project required a large hammering energy. There were 9 rock-embedded piles in the project, with a pile depth of 46 meters, and the difficulty of driving was high. This put forward higher requirements for the construction of the SEMW H450MF double-acting hydraulic pile hammer.
During the construction, the total number of piles sunk in the project was more than 300 steel pipe piles, with a pile diameter of 1~1.5m and a pile depth of 46~67m. The H450MF double-acting hydraulic pile hammer had an average of about 800-900 hammering times per set, ensuring 7-8 piles sunk every day.
At the construction site, the SEMW H450MF double-acting hydraulic pile hammer has a large hammering force, high striking energy density, and large pile penetration during construction; the hammering energy is steplessly adjustable, and the striking energy and working frequency are stable; the hammer body structure is strong and reliable, the system reliability is good, and the impact on the surrounding environment is small; compared with traditional diesel hammers, it is pollution-free, more environmentally friendly, and more energy-saving; the equipment configuration is flexible, the application range is wide, and the adjustment and control capabilities are strong. These construction advantages have made the owners give thumbs up frequently.
The project has been included in the "14th Five-Year Plan" for energy development in Shanghai and the "14th Five-Year Plan" for energy development in Zhejiang Province. After completion, it will further enhance the safety and reliability of natural gas supply in Shanghai, ensure the daily life of residents, and support the daily operation of the industrial system. In the future, this "sea-stabilizing artifact" will continue to gallop across the world and contribute to the construction of lake and sea pile foundations.
HMF series double-acting hydraulic pile hammer product introduction
HMF series double-acting hydraulic pile hammer uses hydraulic energy to lift the hammer core, and then relies on gravity potential energy to hammer the pile end to drive into the pile. It is a hydraulic hammer with a simple structure. It has a compact structure and a wide range of applications. It is suitable for the construction of various pile types and is widely used in pile foundation construction such as buildings, bridges, and docks.
Technical advantages:
● Double-acting hydraulic hammer, especially suitable for inclined pile construction;
● High striking energy density;
● High hammering force and large pile penetration during construction;
● Adopting hammer core elevation measurement and control scheme, hammering energy is steplessly adjustable, striking energy and working frequency are stable;
● Convenient operation, high-end version can display construction data in real time and store it in the database;
● The hydraulic power station works efficiently and reliably, has high volumetric efficiency and low heat generation, and can work continuously for a long time;
● The hydraulic hammer adopts modular design, with a strong and reliable structure and easy maintenance;
● The hydraulic hammer interface is standard, which is convenient for quick replacement of pile caps, replacement, and quick switching of construction of piles of different specifications;
