Abstract
The invention discloses a method for manufacturing a large-diameter steel pipe pile for offshore wind power equipment. The manufacturing method includes the following steps: Step 1: Prepare a steel plate sheet, the thickness of the steel plate is between 45mm-70mm, and the width It is between 3-4 meters, and its length is determined according to the diameter of the required steel pipe pile; Step 2: Roll the steel sheet into a cylinder by a plate rolling machine; Step 3: Adjust the longitudinal direction of the cylinder The gap is welded; step 4: round the welded cylinder; step 5: hoist the three sections of the cylinder to the paired roller frame by a crane, and connect the adjacent two sections of the cylinder The inner and outer ring welds are carried out at the seams. The manufacturing method of large-diameter steel pipe piles for offshore wind power equipment of the present invention solves the difficult problem of processing and manufacturing super-large-diameter and extra-heavy steel pipe piles, provides strong support for the introduction of single-pipe pile construction technology in the offshore wind power industry, and greatly reduces the project costs.
Description
technical field [0001] The invention relates to a large-diameter steel pipe pile used for offshore wind power equipment, in particular to a manufacturing method for the large-diameter steel pipe pile used for offshore wind power equipment. Background technique [0002] The intertidal zone is the area between the high and low tide levels of the spring tide, which is submerged and exposed as the tide rises and falls. According to preliminary estimates, the annual average wind speed in the intertidal zone can reach 6-7 m / s, so there is available wind energy in the intertidal zone. There are also more and more offshore wind power plants. [0003] The biggest difference between offshore wind power generation and onshore wind power generation lies in the location of the two. Since the foundation of the offshore wind turbine is at sea, many additional loads and uncertain factors are added, so the design is more complicated, and the structural form is also due to different The sea...
