Abstract

The construction method comprises the steps that a pair of main lifting lugs is arranged on the left outer side wall and the right outer side wall of the same horizontal plane of the upper portion of the steel pipe pile, a pair of limiting devices is arranged on the front outer side wall and the rear outer side wall of the steel pipe pile, and when the steel pipe pile is put down, positioning blocks are welded to the outer sides of the main lifting lugs and the limiting devices and used for horizontal positioning of the steel pipe pile; and a steel wire measuring rope is mounted at the pile top for controlling the pile top elevation, so that underwater positioning construction of the steel pipe pile is completed. Underwater positioning construction of the steel pipe pile can be achieved, the structure is simple and ingenious, construction is convenient, materials are saved, and construction procedures are simplified; lifting lugs and limiting devices are arranged on the outer side of the upper portion of the steel pipe pile, positioning blocks are welded during lowering construction, the plane position of the steel pipe pile can be accurately controlled, construction is easy and convenient, and operation is flexible; the steel wire measuring rope is adopted to directly measure the pile top elevation of the underwater steel pipe pile, underwater measurement is converted into overwater control, visual and controllable effects are achieved, and underwater construction and underwater measurement work are avoided.

Description

technical field

[0001] The invention relates to the fields of wind power and bridge construction, in particular to a construction method for underwater positioning of steel pipe piles implanted in rock-socketed foundations. Background technique

[0002] In the construction of offshore wind farms, the high technical requirements and complex procedures of foundation construction are the key factors in the construction process of wind farms. There are many types of wind turbine foundations, and the applicable geological conditions vary greatly. Due to the comprehensive influence of factors such as geology, climate, waves, currents, and tides, the appropriate foundation type is very important for the construction of offshore wind farms. Therefore, safety, economic, and The principle of practicality and durability is preferred.

[0003] The implanted rock-socketed foundation is suitable for the fan foundation form with shallow overburden and the pile foundation needs to be embed...
