Abstract

The invention provides a bonding structure of a wind turbine foundation steel ring and concrete and a construction method and belongs to the technical field of wind turbine foundation construction. The bonding structure comprises the wind turbine foundation steel ring and concrete foundations. The lower end of the wind turbine foundation steel ring is arranged in the concrete foundations. The spaces between the inner wall of the wind turbine foundation steel ring and the concrete foundations, between the outer wall of the wind turbine foundation steel ring and the concrete foundations and between an end plate and the concrete foundations are filled with modified epoxy layers respectively. The construction method comprises the step of pouring of modified epoxy. According to the bonding structure of the wind turbine foundation steel ring and the concrete and the construction method, the spaces between the inner wall of the wind turbine foundation steel ring and the concrete foundations, between the outer wall of the wind turbine foundation steel ring and the concrete foundations and between the end plate and the concrete foundations are filled with the modified epoxy layers respectively, so that the wind turbine foundation steel ring and the concrete foundations are bonded into a whole through the modified epoxy, and good toughness and impact resistance are achieved. Therefore, the good effect of stress transfer of the wind turbine foundation steel ring is achieved, and safe operation of a wind turbine generator system is ensured.

Description

technical field

[0001] The invention relates to the technical field of fan foundation construction, in particular to a bonding structure and construction method of a fan foundation steel ring and concrete. Background technique

[0002] The wind turbine foundation, also known as the wind turbine foundation, is an important part of ensuring the normal operation of the wind turbine unit. It must bear various loads transmitted from the wind turbine tower to the foundation through the foundation steel ring.

[0003] The traditional wind turbine foundation steel ring has smooth inner and outer walls, shallow embedding depth, few openings, poor bonding between the foundation reinforced concrete and the wind turbine foundation steel ring, and poor bonding stress transfer effect, so anchoring accidents of the wind turbine foundation steel ring often occur. The main manifestations are that after the concrete is poured, a certain amount of shrinkage and fine cracks occur between the co...
