Moreover, there are many types of fan foundation forms, and the applicable geological conditions vary greatly, being comprehensively affected by factors such as geology, climate, waves, water flow, and tides.

[0003] For the fan foundation form where the overburden layer is relatively shallow and the pile foundation needs to be embedded into the rock layer below moderately weathered rock, it is necessary to process an auxiliary drilling platform to meet the construction requirements of this type of geology. The processing efficiency of the drilling platform is crucial for the construction of offshore wind farms. Therefore, it should be selected preferably following the principles of safety, economy, practicality, and durability.

[0004] The drilling platform is a super-large component for processing. During the processing, it is difficult to adjust the level of the drilling platform. Due to the large lifting accuracy of large cranes, it is necessary for the measurement team to repeatedly measure and the crane to repeatedly adjust its position to achieve the design position accuracy. This not only wastes manpower but also increases the equipment usage cost. To ensure the level adjustment during the manufacturing process, simplify the difficulty of leveling components during processing, speed up the overall construction progress of components, and at the same time ensure the safety and controllability during the construction process and save costs, there is an urgent need to invent a construction method for leveling large scaffolds.

The leveling device consists of a first wedge block at the lower part, two second wedge blocks on the left and right respectively, and a third wedge block at the upper part. The first wedge block and the third wedge block are exactly the same. The sum of the bottom angles of the first wedge block and the second wedge block is 90 degrees. The first wedge block, the two second wedge blocks, and the third wedge block are combined together according to their positions; the locking device consists of precision rolled threaded steel and nuts. The middle symmetrical parts of the two second wedge blocks on the left and right are connected by precision rolled threaded steel and nuts to form an integral body; B. Before assembling the large scaffold group, place a leveling device on the top of each pier. Multiple leveling devices are on the same straight line.

Adjust the distance between the two second wedge blocks by adjusting the position of the nut of a leveling device that needs to be adjusted, thereby jacking up or lowering the height of the combination of the third wedge block and the saddle, so as to achieve the required adjusted height; G. Repeat step F until all leveling devices are adjusted to ensure that the structure is on the same horizontal plane.

[0007] Furthermore, the first wedge block, the second wedge block, and the third wedge block in step A are all made of steel plates.
