Single-pile foundation for electric transmission line and method for manufacturing single-pile foundation

Abstract

The invention discloses a single-pile foundation for an electric transmission line and a method for manufacturing the single-pile foundation, and belongs to the field of single-pile foundation manufacturing. The single-pile foundation comprises multiple connecting longitudinal ribs and a columnar pile body with at least four columnar embedded parts. The multiple connecting longitudinal ribs are located around the portions, outside a target end face, of the at least four columnar embedded parts. The multiple connecting longitudinal ribs are provided with binding structures. The target end faceof the columnar pile body is provided with an isolating layer, and the at least four columnar embedded parts penetrate through the isolating layer. Protection sleeves are arranged at the ends, on thetarget end face, of the at least four columnar embedded parts. The multiple connecting longitudinal ribs are provided with first metal net sheets. A concrete protection cap is poured to the side, awayfrom the columnar pile body, of the isolating layer. The problems that in the correlation technique, when the single-pile foundation is subjected to secondary pouring, the construction period is long, and the quality of the single-pile foundation during secondary pouring is hard to guarantee are solved, and the effects of shortening the construction period and guaranteeing the quality of the single-pile foundation are 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...
