PREFABRICATED HIGH-STRENGTH CONCRETE COMBINED PIER STRUCTURE AND CONSTRUCTION METHOD THEREOF
Abstract The invention discloses a prefabricated high-strength concrete combined pier structure and a construction method thereof. The pier structure comprises a concrete pile, a concrete base and 5 a pier, wherein the concrete pile is arranged below the concrete base, and the pier comprises at least one pier unit. The pier unit comprises an inner pier, an outer pier, an inner pier foot guard and an outer pier foot guard, wherein the inner pier is of an integral full-length hollow structure, and the outer pier is of an integral full-length hollow structure or an assembled hollow structure. The upper part of the concrete base is provided with at least one boss, and a 10 separating ring-belt is arranged between the inner pier and the outer pier. The combined pier structure according to the present invention has the advantages that it is convenient for manufacturing, hoisting and transporting, and has simple, convenient and fast construction process. Apart from that, the construction period can be shortened via an on-site assembling mode, and on-site manpower and construction cost can be reduced; and according to the 15 invention, as the combined pier structure can be poured separately, the strength grades of the separately poured concrete are different such that the construction cost can be reduced under the condition of ensuring the installation quality of the pier. 1--1
