Description

Prefabricated tower foundation

The present invention relates to a prefabricated steel tower foundation, and more particularly, to a prefabricated steel tower foundation to be installed after the steel tower foundation is partially assembled to assemble and integrate each part in the field.

In general, a transmission tower is a truss-type steel structure that is constructed at tens of meters above ground in order to construct a transmission line, etc., and has a weight of several tens to hundreds of tons. Such transmission towers usually have four main materials arranged in the forward direction, and the lower end of each main material is fixed to the ground by a concrete foundation.

In order to install the transmission tower, first, the ground is dug to form a flat concrete surface, and then four basic concrete structures are arranged in a square shape, and angles are sequentially arranged in a truss shape up to a set height of each foundation concrete structure. The method of assembly and completion is applied.

Transmission tower foundations that support transmission towers are usually manufactured on-site, which requires considerable weight, equipment, and a large work space.However, given the areas where the transmission towers are installed, such as mountains, ridges, steep slopes It is difficult to move materials, equipment, etc., and the size of the basic construction is large, causing environmental destruction, and the construction period takes a long time.
