Prefabricated-type high-rise pile cap foundation and construction method thereof

Abstract

The invention provides a prefabricated-type high-rise pile cap foundation and a construction method thereof. The prefabricated-type high-rise pile cap foundation comprises a prefabricated cap main body and a plurality of piles used for supporting the prefabricated cap main body. A plurality of pile-embedding compartments with upward openings are formed on the prefabricated cap main body, all the pile-embedding compartments and all the piles are in one-to-one correspondence, pile-penetrating holes are formed in the bottoms of the pile-embedding compartments and downwards penetrate to the bottomface of the prefabricated cap main body, and supported parts extending transversely are arranged on the side walls of the pile-embedding compartments. The upper ends of the piles pass through the pile-penetrating holes to extend into the pile-embedding compartments, and the upper ends of the piles are connected with the supported parts through height adjusters. The pile-embedding compartments arefilled with building structure materials, and the building structure materials enable the prefabricated cap main body and all the piles to be fixedly connected into a whole. The offshore operation time of the high-rise pile cap foundation is reduced, the overall construction period of the high-rise pile cap foundation is shortened, and the offshore application range of the high-rise pile cap foundation is expanded.

Description

technical field [0001] The invention relates to a fan foundation of an offshore wind farm, in particular to a prefabricated high pile cap foundation and a construction method thereof. Background technique [0002] In recent years, the greenhouse effect and global warming have become global environmental crises. Therefore, clean and green energy must become a future trend, and wind energy is one of them. my country has a vast territory, long coastline, and abundant offshore wind energy resources. Offshore wind farms have the advantages of high wind speed, long effective power generation time, do not occupy land, and are close to the load center, etc., and have good prospects for development. The wind turbine high pile cap foundation is the first wind turbine foundation form in my country. The high pile cap foundation has low requirements for construction machinery and tools, and there are many operating teams that can be constructed, and the technology is mature. It has be...

AI Technical Summary

Problems solved by technology

[0003] However, the high-pile cap foundation requires offshore formwork, offshore tying of steel bars, and pouring of concrete. The offshore operation takes a long time and the construction period is long, and it cannot adapt to the conditions of few offshore operation windows, which greatly limits its application.
