Abstract

The invention discloses a prefabricated anchoring base for a frozen soil foundation and an installation method. The prefabricated anchoring base is characterized by comprising a pile body, a spiral pull rod, a base top anchoring cushion block and a base bottom anchoring cushion block. The prefabricated anchoring base adopts reinforced concrete prefabricated piles, the pile body of each pile is divided into three parts, one is a conical column segment, the second one is a straight column segment, and the third one is a base pedestal, wherein the pile side face of the conical column pile segment is an oblique face, and therefore partial tangential frost heaving force can be subducted through gravity; and wrapping glass cloth on the side face of the conical column segment of the prefabricated anchoring base can be completed in a factory, and the construction quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of transmission line iron tower foundations, and in particular relates to a prefabricated anchor foundation and an installation method for permafrost foundations. Background technique [0002] Permafrost refers to various rocks and soils below zero degrees Celsius and containing ice. Permafrost is roughly divided into: short-term frozen soil, seasonal frozen soil and permafrost (also known as permafrost). The area of ​​permafrost / seasonal frozen soil and short-term frozen soil on the earth accounts for about 50% of the land area, of which the permafrost area accounts for 25% of the land area. The areas of permafrost and seasonal permafrost in China account for 21.5% and 53.5% of the country's land area respectively, and are mainly distributed in the Qinghai-Tibet Plateau, high mountains in the northwest, and the Greater and Lesser Khingan Mountains and the Songnen Plain in the northeastern part of China. ...
