Embodiment Construction

[0045] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0046] When transmission lines pass through river networks, swamps, ponds and other areas, the single pile foundation with embedded parts in the columnar pile body is usually used to connect with the tower.

[0047] 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 during high-strain testing. Therefore, the high-strain testing is performed on the single pile foundation without embedded parts first, and then the high-strain testing will be carried out. A predetermined section of the columnar pile on the top of the detected single pile foundation is chiseled off, and then the embedded parts are set at the predetermined position, and the single...

Abstract

The application discloses a single-pile foundation and a method for manufacturing the single-pile foundation, which belong to the field of single-pile foundation manufacturing. The single pile foundation includes: a columnar pile body with a strip-shaped embedded part and multiple connecting longitudinal reinforcements, a plurality of connecting longitudinal reinforcements surround the strip-shaped embedded part, and the length direction of the strip-shaped embedded part is parallel to the length direction of the tower foot , multiple connecting longitudinal reinforcements have a binding structure; the target end face of the columnar pile body has an isolation layer, and the strip-shaped embedded part and multiple connecting longitudinal reinforcements pass through the isolation layer; the strip-shaped embedded part is located outside the target end surface and has A protective cover; a plurality of connecting longitudinal reinforcements are provided with metal mesh sheets; a concrete protective 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 single pile foundation and a method for manufacturing the single pile 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 during high-strain testin...
