Description

Technical Field

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

[0002] When the transmission line foundation project faces blizzards, earthquakes and other natural disasters, the poles and foundations are severely damaged and the original tower position can no longer be used. It is necessary to re-select the location to build the foundation and assemble the poles. The original poles and foundations will be dismantled after the emergency repairs are completed. The prefabricated foundations of power equipment mainly include two forms: plate foundations cast in reinforced concrete with concrete as the main component and conical steel prefabricated foundations used in high-voltage transmission line projects. There are few studies on the commonly used all-metal prefabricated foundations for emergency rescue and low-voltage lines.

[0003] When the line foundation is damaged, due to the strength limitation of the foundation concrete curing period, it usually takes 7 days for the foundation to reach the tower assembly strength, and about 21 days to reach the line strength. The emergency repair time is more than 25 days. It can be seen that the construction of traditional foundations usually requires a long construction period, requiring land preparation, excavation, concrete pouring and maintenance. Therefore, the recovery time of the damaged tower foundation is relatively long, but the power supply of the people in the power supply area of ​​the line is urgent. The traditional cast-in-place foundation cannot meet the tower assembly requirements in a short time, and the concrete prefabricated foundation is difficult to transport for mountainous lines with inconvenient transportation. In addition, the construction of traditional foundations usually needs to be carried out on site, which cannot achieve rapid construction and modular mobility, which is not conducive to responding to emergencies or scenarios that require frequent migration.

[0004] In this regard, the comparative document (CN216108594U) proposed an assembled metal support foundation for 330kV transmission line projects, and the comparative document (CN214832857U) proposed an adjustable metal assembled foundation. However, these two metal assembled foundations are mainly suitable for pole tower foundation projects of high-voltage transmission lines. Specific technologies and materials are designed for this level of voltage to ensure stability and durability. The foundation is mainly adapted to a specific tower type, which has limitations for different tower types for emergency repairs. In addition, the comparative document (CN214832857U) requires that there is no groundwater above the bottom of the foundation. When the above technical solutions are applied to low-voltage line projects, there are defects such as complex processing and low cost-effectiveness, and they are not suitable for repair projects with low voltage levels or multiple different tower types.
