Super-large-diameter prestressed concrete tubular pile for offshore wind power and construction method thereof

Abstract

The invention discloses a super-large-diameter prestressed concrete tubular pile for offshore wind power and a construction method thereof.The concrete tubular pile comprises a reinforcement cage framework, and the reinforcement cage framework adopts a double-layer bidirectional mixed reinforcement mode and comprises an outer ring layer, an inner ring layer and a connecting layer connecting the outer ring layer and the inner ring layer into a whole; the outer ring layer comprises outer ring layer longitudinal bars and outer ring layer stirrups, and the inner ring layer comprises inner ring layer longitudinal bars and inner ring layer stirrups; the outer ring layer longitudinal bars and the inner ring layer longitudinal bars are tied through tie bars, and the tie bars form the connecting layer. Therefore, the corrosion of seawater and salt mist to the fan foundation and the damage of marine organisms to the structural foundation can be effectively reduced, the problem of corrosion resistance of the fan foundation is well solved, and the concrete base material is adopted, so that the engineering cost can be reduced, the construction is convenient, and the operation and maintenance cost is reduced and the operation and maintenance efficiency is improved under the pressure of reducing the cost on average price.

Description

technical field [0001] The field of the invention is the technical field of offshore wind power pile foundation engineering, in particular to a super-large-diameter prestressed concrete tubular pile for offshore wind power and a construction method thereof. Background technique [0002] my country is rich in offshore wind power resources, and has the characteristics of high operating efficiency, short transmission distance, convenient on-site consumption, no land occupation, and suitable for large-scale development. Offshore wind power will become an inevitable choice for my country to vigorously develop renewable energy. Among the variables that ensure the safe and stable operation of offshore wind power, basic engineering is a very important one. Due to the special conditions of offshore construction and operating environment, the stability, durability and economy of the basic engineering of the structure are particularly important. [0003] Offshore wind power foundation...
