Description

technical field

[0001] The invention relates to the field of construction engineering, in particular to a spiral cartridge type composite spiral anchor and a spiral cartridge. Background technique

[0002] Spiral anchor foundations are used in construction engineering (such as steel structures, etc.), power engineering (substations, transmission lines, etc.), communication towers and other fields.

[0003] In the engineering construction of high-voltage transmission lines, it is inevitable to pass through weak geological areas such as silt. In the past, the tower foundations in such areas mostly used large slab foundations, pile foundations, cast foundations or gravity foundations. It is safe, but the material consumption is large, the foundation pit is difficult to excavate, the investment is large, and the construction period is long. The advantages of simple manufacture, convenient installation and construction, short construction period, low cost, and little damage to t...
