Description

Technical Field

[0001] The utility model provides an adjustable assembled all-metal joint foundation for a power transmission tower, belonging to the field of power transmission line iron towers. Background Art

[0002] The construction of traditional foundations usually requires a long construction period. In order to achieve rapid construction after natural disasters, ensure the continuity of power transmission, and reduce the difficulty of emergency repairs, there are currently assembled metal support foundations for 330kV transmission line projects. However, this assembled metal support foundation is mainly suitable for the tower foundation project of high-voltage transmission lines, and specific technologies and materials are designed for this level of voltage to ensure stability and durability. When applied to low-voltage systems, this technology and method will appear inapplicable or have limitations due to processing complexity and cost-effectiveness. This single applicability limits its wide application in transmission line projects with different designs or requirements. Further adjustments or improvements are needed in low-voltage or diversified demand environments to improve its applicability and flexibility. In addition, the root opening (the distance between tower legs) of low-voltage transmission towers is small. For transmission towers with smaller root openings, traditional assembled independent foundations often have foundation base collision problems. Utility Model Content
