Concrete tower drum section and tower

Abstract

The invention discloses a concrete tower drum section and a tower. The concrete tower drum section comprises a bottom end drum section. The inner surface of the bottom end drum section is sunken in the radial direction to form a tensioning operation chamber used for tensioning a prestress cable, the tensioning operation chamber comprises multiple first operation chambers and multiple operation chambers, and bottom end drum section prestress hole channels are formed in the bottom end drum section. The bottom end drum section prestress hole channels include the first hole channels formed by extending downwards from the upper end surface of the bottom end drum section and the second hole channels formed by extending upwards from the lower end surface of the bottom end drum section, wherein inthe circumferential direction of the bottom end drum section, the first hole channels of a first number and the second hole channels of a second number are arranged staggered, a lower end opening ofeach first hole channel is formed in the corresponding second operation chamber, an upper end opening of each second hole channel is formed in the corresponding first operation chamber, the bottom enddrum section can be suitable for a solid tower drum foundation, and the manufacturing cost of the tower drum foundation is reduced.

Description

Technical field[0001]The present invention belongs to the field of wind turbine, and is related to a concrete tower barrel and a tower including the concrete tower barrel.Background technique[0002]At present, the tray of wind turbines usually has steel tower, concrete tower, and steel-concrete tower.[0003]Concrete tower and steel-concrete tower typically include concrete tower barrels, which is tested by a prestressed cable and securely coupled to the tower base. The prestressed tensile end is typically located inside the tower base. In order to facilitate the installed person to perform the pre-vesting of the concrete tower bar, the tower is formed as a hollow foundation formed by the concrete material, which can be It has an operating space suitable for installation personnel, and the tensile terminal is exposed to the operating space. A large number of engineering practice shows that although the hollow foundation has decreased in the amount of concrete engineering, it is much gr...

AI Technical Summary

Problems solved by technology

A large number of engineering practices have shown that compared with ordinary solid foundations, although the amount of concrete works has been reduced, the amount of steel bars used in hollow foundations is much greater than that of solid foundations. Therefore, the manufacturing cost of hollow foundations is higher than that of solid foundations, resulting in Towers with hollow foundations are more expensive to manufacture
