the interior of the embedded pile compartment 3 is filled with building structural materials which fixedly connect the prefabricated pile cap main body 1 and all piles 2 into a whole. The building construction materials include concrete, mortar, grouting material, etc., and in a specific embodiment, concrete is preferably used to cast the interior of the buried pile compartment 3.
In the invention, the prefabricated pile cap main body 1 and all piles 2 are prefabricated in the prefabricated field, so that the construction efficiency of constructing the high pile cap foundation at sea is greatly improved; as the prefabricated bearing platform main body 1 and all piles 2 are prefabricated, the construction procedures on the sea are reduced, the construction difficulty on the sea is reduced, and the influence factors on the sea during construction are also greatly reduced. The upper part of each pile 2 is connected with the supported part through the height adjuster, and the prefabricated pile cap body 1 can be leveled through the height adjuster before the prefabricated pile cap body 1 and all piles 2 are fixedly connected into a whole, so that the prefabricated pile cap body 1 meets the design requirement of basic flatness. Therefore, the invention reduces the offshore operation time of the high-pile cap foundation, shortens the overall construction period of the high-pile cap foundation, and expands the offshore application range of the high-pile cap foundation.
In order to prevent the seawater from splashing to the top surface of the prefabricated platform body 1, the upper peripheral edge of the prefabricated platform body 1 extends in a direction away from the center of the prefabricated platform body to form a breakwater 5. In a specific embodiment, the breakwater 5 is a horizontally arranged annular plate, the annular plate can be integrally formed with the prefabricated platform main body 1, and the top surface of the annular plate is in transitional connection with the top surface of the prefabricated platform main body 1. Further, the outer circumference of the annular plate is lower than the inner circumference of the annular plate, so that even if the sea water jumps to the upper circumference of the prefabricated deck body 1, the sea water can flow back into the sea.
The prefabricated pile cap main body 1 comprises a bearing plate 1a, an inner annular wall 1b and an outer annular wall 1c, wherein the inner annular wall 1b and the outer annular wall 1c are coaxially arranged on the bearing plate 1a, an annular groove between the inner annular wall 1b and the outer annular wall 1c is divided into a plurality of pile-embedded compartments 3 by a plurality of partition plates 6, and the pile penetrating holes 4 are formed in the bearing plate 1a forming the bottom of the pile-embedded compartments. The prefabricated bearing platform main body 1 adopts the structure, and has simple and stable structure and short construction period. In order to facilitate the installation of the fan tower on the inner annular wall 1b, the inner annular wall 1b is embedded with a fan tower connection structure, and the fan tower connection structure specifically comprises a foundation ring or a prestress anchor bolt.
In order to avoid water accumulation on the prefabricated bearing platform main body 1, the top surface height of the prefabricated bearing platform main body 1 gradually decreases from the center of the prefabricated bearing platform main body to the outside. In a specific implementation, if the prefabricated pile cap body 1 adopts the structural forms of the bearing plate 1a, the inner annular wall 1b and the outer annular wall 1c, the top surface of the inner annular wall 1b is higher than the top surface of the outer annular wall 1c, the top surface of the building structural material (such as concrete) filled in the embedded pile compartment 3 is in a gentle slope form, and the accumulated water on the prefabricated pile cap body 1 can flow back into the sea in a proper manner.
The supported portion is a supported beam 7, two ends of the supported beam 7 are fixedly connected with the side wall of the embedded pile compartment 3, and in a specific implementation, if the prefabricated pile cap main body 1 adopts the structural form of the bearing plate 1a, the inner annular wall 1b and the outer annular wall 1c, the supported beam 7 extends along the radial direction of the inner annular wall and the radial direction of the outer annular wall, that is, one end of the supported beam 7 is connected with the outer Zhou Bigu of the inner annular wall 1b, and the other end of the supported beam 7 is connected with the inner Zhou Bigu of the outer annular wall 1c, so that the structure between the inner annular wall 1b and the outer annular wall 1c is more stable due to the connecting structure. As a preferred design of the supported beams 7, all supported beams 7 are located on the same horizontal plane, which facilitates the leveling operation.
The height adjuster comprises a supporting base 8 and a jack 9, wherein the supporting base 8 is arranged at the upper end of the pile 2, the jack 9 is arranged on the supporting base, and the supporting end of the jack 9 is propped against the supported part.

After the leveling operation of the prefabricated pile cap main body 1 is completed, the gap between the upper end of the upper pile 2 and the supported part can be sealed first, and when the building structural material is filled into the embedded pile compartment 3, the protection cavity 2a can protect the support base 8 and the jack 9, so that the support base 8 and the jack 9 are prevented from being punched by the building structural material.
In order to hoist the prefabricated bearing platform main body 1, a hoisting assembly is arranged on the prefabricated bearing platform main body 1. In particular embodiments, the lifting assembly includes a plurality of lifting lugs 10, and the lifting lugs 10 may be disposed on the supported portion.
