Description

Technical Field

[0001] The utility model relates to the technical field of overhead transmission lines, and more specifically, to a prestressed anchor pile anti-pulling foundation for an overhead transmission line. Background Technique

[0002] Overhead lines mainly refer to overhead open wires, which are erected above the ground. They are transmission lines that use insulators to fix transmission conductors on poles standing upright on the ground to transmit electric energy. When erecting overhead lines in mountainous areas, it is necessary to pour erection foundations on slopes.

[0003] After retrieval, the utility model patent with the publication number of CN210395412U discloses a prestressed anchor pile anti-pulling foundation suitable for mountainous area overhead transmission lines, which includes a main column, a bearing platform, and several prestressed anchor piles; the main column is erected above the bearing platform, the bearing platform is buried underground, and the column and the bearing platform are cast integrally; a tower foot plate is provided on the upper end surface of the column, an embedded steel plate is provided in the bearing platform, and the upper and lower ends of the anchor bolts are respectively fixed on the tower foot plate and the embedded steel plate through nuts; the prestressed anchor pile includes an anchor bar, the lower part of the anchor bar is an anchorage section anchored underground, and the upper part of the anchor bar is a free section locked on the upper surface of the bearing platform after tensioning the prestress; this foundation type has the advantages of low requirements for terrain and geology, being able to carry out mechanized construction, good anti-corrosion performance, and low concrete consumption, and can overcome the limitations of the application of dug foundations and anchor pile foundations.

[0004] However, the above patent still has the following deficiencies: The column is arranged on the slope, and the flowing water during rain will wash the soil outside the column, which will expose the bearing platform buried in the ground and affect the support of the bearing platform for the transmission line tower; moreover, the prestressed anchor piles are vertically inserted into the ground, and the fixing effect of the ground on the prestressed anchor piles is poor, and at the same time, it will affect the firmness of the bearing platform. Therefore, we propose a prestressed anchor pile anti-pulling foundation for an overhead transmission line. Content of the Utility Model
