Land wind turbine foundation drainage system
The invention belongs to the technical field of wind turbines and particularly relates to a land wind turbine foundation drainage system. The land wind turbine foundation drainage system is technically characterized in that a ring of rain shields is arranged at the position, higher than the surface of concrete by a certain distance, of the outer wall of a steel cylinder along a cylinder body of the steel cylinder, an annular open trench surrounding the steel cylinder is formed in the ground away from the outer wall of the steel cylinder by a certain distance, the annular open trench is communicated with two direct discharging open trenches, and the ends of the two direct discharging open trenches are each provided with a water collecting well or the two direct discharging open trenches discharge rainwater directly according to terrain; an apron is formed in the ground between the annular open trench and the steel cylinder by making a slope through mortar building materials; factice dampproof coatings are arranged on the inner wall and the outer wall of the cylinder body of the steel cylinder and located in a certain up-down area of the contact surface of the outer wall of the steel cylinder and the surface of the concrete. The complete drainage system is designed for preventing rainwater from eroding and damaging concrete on the steel cylinder and concrete contact interface in a wind turbine foundation, preventing a crack from further expanding, and effectively guaranteeing the reliability of the wind turbine foundation.
