Abstract

The invention discloses an assembly type metal support foundation for 330kV power transmission line engineering and a construction method of the assembly type metal support foundation. The foundation comprises a tower foot plate, a metal support, a support inclined strut, a cross beam and a foundation bottom plate. The whole support is of a rectangular pyramid structure, the metal supports are located on the ridge lines of the rectangular pyramid, the tower foot plate is arranged at the top ends of the metal supports, and the two ends of the support inclined strut are connected with the two adjacent metal supports. The metal bracket is arranged on the cross beam; the cross beam is arranged on the connecting bottom plate; the whole assembly type metal support foundation is in a rectangular pyramid form, all-metal components are adopted, the foundation structure form is simple, and force transmission is clear; the foundation type can be processed in factories and assembled on site, and is convenient to disassemble and transport; concrete pouring and foundation maintenance are not needed, the fabricated foundation can be machined in a factory and transported to a construction site in the form of parts, foundation pit backfilling can be carried out only by assembling on site, meanwhile, foundation pit excavation can be synchronously carried out while components are machined, and the construction period can be greatly shortened.

Description

Technical field [0001] The present invention relates to the field of transmission line tower technology, and more particularly to the assembly metal bracket foundation and construction method thereof for 330KV transmission line engineering. Background technique [0002] In recent years, due to changes in climate or geological conditions, it has emerged, such as the construction of the construction period, such as repairing the 330KV line. The basic form of conventional 330KV transmission line is mainly two types of board bases and artificial excavation, these basic forms are in the form of reinforced concrete structures, and they need to latenate steel bars, pouring concrete, and then carrying concrete maintenance. There are more work hours, but the reinforcing concrete foundation will give a subsequent group tower and the disposal of the tower and the disposal is caused. [0003] The prefabricated assembled foundation is increasingly widely used in transmission lines. It saves o...
