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

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 stru
