Embodiment Construction

[0057] The present invention will be further described below in conjunction with accompanying drawing.

[0058] see figure 1 Referring to Fig. 5, the large-diameter steel pipe pile for offshore wind power of the present invention includes a steel pipe pile body 11 and lifting lugs 12; wherein, the steel pipe pile body 11 is formed by butt welding of several steel pipe pile joints 110;

[0059] The lifting lug 12 is fixed on the outer wall surface of the upper half of the steel pipe pile body 11;

[0060] Below the pile top of the steel pipe pile body 11, the middle part of the second steel pipe pile joint 110 is provided with several air holes 13 evenly distributed along the wall surface of the pile, and several air holes 13 are all connected with the steel pipe pile body 11. The attached components on the top are staggered; the number of vent holes 13 can be set according to actual needs, and the number of vent holes 13 in this embodiment is two.

[0061] Each ventilation hol...

Abstract

The invention discloses an offshore wind power large-diameter steel pipe pile which comprises a steel pipe pile body and lifting lugs; the steel pipe pile body is formed by welding a plurality of steel pipe pile pipe sections in a butt joint manner; the lifting lugs are fixed on the outer wall surface of the upper half part of the steel pipe pile body; and a plurality of vent holes are uniformly distributed in the middle of the second steel pipe pile section below the pile top of the steel pipe pile body along the peripheral wall surface of the pile, and the vent holes are staggered from auxiliary components on the steel pipe pile body. According to the offshore wind power large-diameter steel pipe pile, the vent holes are formed, gas in the pile can be exhausted in time, the jacking forceof compressed gas in the pile on a hydraulic hammer can be effectively reduced, the situation that the hydraulic hammer is separated from the steel pipe pile during pile sliding is eliminated, and damage to a large construction ship and the large hydraulic hammer is avoided.

Description

technical field [0001] The invention relates to a large-diameter steel pipe pile for offshore wind power. Background technique [0002] In recent years, offshore wind power has developed rapidly, and single pile foundation is currently the most widely used foundation form. With the increase of offshore wind turbines, the diameter and weight of single pile foundations are getting larger and larger, and the construction of single pile foundations is becoming more and more difficult. The underwater geological conditions of offshore wind power construction are complex, there are soft soil interlayers in some sea areas, the foundation soil is liquefied seriously, and the risk of "pile slipping" of large-diameter steel pipe piles is high. According to the statistics of pile sinking construction in offshore wind farms in recent years, the phenomenon of "sliding piles" of large-diameter steel pipe piles in the coastal waters of Jiangsu is relatively frequent, and there are long dis...
