Problems solved by technology

[0005] In the use of the foundation ring foundation, the connection effect between the foundation ring and the foundation is poor. When the load is large, the foundation ring will be pulled out from the foundation ring foundation, and the steel bars connected to the foundation ring will be pulled out at the same time.

Abstract

The invention relates to a foundation ring rock anchor rod foundation.The foundation ring rock anchor rod foundation comprises a foundation ring foundation made of concrete and a concrete cushion layer arranged outside the foundation ring foundation in a sleeving mode, the foundation ring foundation and the concrete cushion layer are of a cylindrical solid structure, a foundation ring is arranged on the foundation ring foundation, reinforcement cages are fixed inside and outside the foundation ring, a middle steel formwork is arranged between the reinforcement cages and the concrete cushion layer, an inner steel formwork is embedded into the inner sides of the reinforcement cages, and an outer steel formwork is arranged at the outer side of the concrete cushion layer in a sleeving mode.The reinforcement cages are welded inside and outside the foundation ring, connectivity between the foundation ring and the foundation concrete is improved, and stability of the foundation ring is improved; by means of the technology of additionally arranging corrugated cylinders around the foundation ring, burial depth of the foundation ring is ensured on the condition that the foundation ring is wrapped by the inner and outer cylinders, the pull-out capacity of the foundation ring is improved, and the anti-side-pressure capacity of concrete around the foundation ring is improved.

Description

technical field [0001] The invention relates to the technical field of wind power tower foundation reinforcement, in particular to a foundation ring rock bolt foundation. Background technique [0002] As one of the most mature, large-scale development and commercial development methods in the field of renewable energy, wind power has gradually become an important direction for the development of renewable energy, especially in Inner Mongolia, Gansu, Xinjiang, Hebei and Jiangsu. The planning of six 10 million KW wind power bases in resource-rich areas also fully demonstrates the broad prospects of the wind power industry. However, with the large-scale development of wind farms, the difficulties and problems in the construction process of wind turbines have gradually been exposed, one of which is the stability of the foundation of the wind turbine and the degree of pull-out resistance. [0003] The fan foundation is a steel-concrete composite structure composed of steel rings...
