With the continuous expansion of the power grid, the voltage level gradually increases, and the needs and requirements for the power distribution network framework also gradually increase.

[0003] The power distribution network framework is used to support high-voltage transmission lines, substation equipment and other power infrastructure. Generally, high-strength and corrosion-resistant truss steel structures are adopted as the main structure, which has good integrity, strong seismic resistance and high structural safety. The existing power distribution network frameworks have high requirements for the foundation during installation. Generally, concrete foundations are used to provide stable support for the framework. The actual construction includes preparation, design measurement, formwork support, pouring and then removing and curing the foundation, etc., with high costs, long time consumption and low installation efficiency of the power distribution network framework. Content of the Utility Model
