Abstract

The invention discloses a reinforced structure and method of P and H type rock bolt fan foundation. The structure includes a reinforcement cage arranged outside a foundation platform and a bottom tower tube and concrete integrated with the reinforcement cage in a pouring mode, the foundation platform and the poured concrete form a cantilever plate of the reinforcement foundation, and the bottom tower tube and the poured concrete form a column pier of the reinforcement foundation; the method comprises the following steps of one, installation of a planting bar; two, welding of welding nails; three, binding of a reinforcement cage; four, installation of a circumferential prestressed steel strand; and five, pouring of the concrete. According to the reinforced structure and method, the design is reasonable, reinforcement of the P and H type rock bolt fan foundation is realized, stress of the P and H type rock bolt fan foundation is stable, bearing capacity requirements are met, the reinforcement effect is excellent, and the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of fan foundation reinforcement construction, and in particular relates to a P&H rock bolt fan foundation reinforcement structure and method. Background technique [0002] With the increase of population, energy and environment have become the two main problems that people are facing. On the one hand, the continuous consumption of traditional fossil fuels prompts people to seek new energy as an alternative; on the other hand, traditional fossil fuels will lead to increased air pollution and carbon dioxide levels, causing the greenhouse effect. Wind power has the characteristics of clean and pollution-free, large unit capacity, good economic and social benefits, and is currently one of the most promising new energy sources. When the wind turbine is running, the alternating loads such as aerodynamic force, inertial force and elastic force acting on the blades are transmitted to the fan foundation through the ...
