Monopile foundation for power transmission line and method for manufacturing the monopile foundation

Abstract

The application discloses a single-pile foundation for power transmission lines and a method for manufacturing the single-pile foundation, belonging to the field of single-pile foundation manufacturing. The single pile foundation includes: a plurality of connecting longitudinal reinforcements and a columnar pile body with at least four columnar embedded parts, the plurality of connecting longitudinal reinforcements are located around the part of the at least four columnar embedded parts outside the target end surface, and the plurality of connecting longitudinal reinforcements The tendon has a binding structure; the target end face of the columnar pile body has an isolation layer, and at least four columnar embedded parts pass through the isolation layer; at least four columnar embedded parts are provided with a protective cover on one end outside the target end face; multiple connecting longitudinal A first metal mesh sheet is provided on the reinforcement; a concrete protection cap is poured on the side of the isolation layer away from the columnar pile body. The invention solves the problems in the related art that when the single pile foundation is poured twice, the construction period is long and it is difficult to guarantee the quality of the single pile foundation during the second pour. The effect of reducing the construction period and ensuring the quality of the single pile foundation is achieved.

Description

technical field [0001] The present application relates to the field of monopile foundation manufacturing, in particular to a monopile foundation for power transmission lines and a method for manufacturing the monopile foundation. Background technique [0002] The monopile foundation is an important part of the transmission line, including a columnar pile body made of concrete and embedded parts, wherein the embedded part exposes the end face of the top of the columnar pile body for connection with the pole tower. After the monopile foundation is manufactured, it is usually necessary to carry out high-strain testing on the single-pile foundation. High-strain testing requires an impact force to be applied to the top of the single-pile foundation to check whether the quality of the single-pile foundation meets the requirements. [0003] In the related technology, since the embedded parts expose the end surface of the top of the columnar pile, there is a risk of being damaged du...
