Description

Technical Field

[0001] The utility model relates to the technical field of power transmission iron towers, in particular to a mounting base for power transmission line iron towers. Background Art

[0002] The transmission tower is the supporting point of the overhead line. If one circuit is erected on the transmission tower, it is a single-circuit transmission tower. If two circuits are erected on the transmission tower, it is a double-circuit transmission tower. A single circuit refers to a circuit with one power supply for one load; a double circuit refers to a circuit with two power supplies for one load.

[0003] A base is required for the installation of an iron tower, and most common bases are formed by direct pouring of concrete. When concrete is under pressure, it usually supports the pressure through its own rigidity and is unable to absorb and buffer the pressure. In addition, concrete takes a long time to solidify, making it inconvenient to use. At the same time, when the support column bears the weight of the tower, the pressure is transferred to the underground in a very small area. The ground will sink under the pressure, which can easily affect the progress of construction. Utility Model Content
