Spiral earth anchor fixing in the construction
Dec 02, 2022| Spiral earth anchor is a simple pile used for fixing cable or temporary fixing in the construction process. It is composed of one or more spiral bearing plates attached to the central axis. In use, the rotary anchor drill is used to rotate the ground anchor into the ground, and the tension between the spiral blade of the anchor and the soil layer is used to achieve the fixed effect.
Spiral ground anchor is widely used in the construction of large tower because of its corrosion resistance, large torque, short installation period and stable effect of different soils.
Spiral ground anchor application
Field installation of transmission towers
In long-distance transmission lines, spiral ground anchors can be used to fix the bottom of high-voltage transmission towers under transportation difficulties, high water level, marshland, soft ground and other environments, and can effectively cope with the harsh outdoor environment and sand, gravel and other soil, to ensure the reliability of transmission towers.
Installation of communication towers and power towers
Spiral anchors are suitable for stabilizing the bottom of large communication towers and power towers due to their powerful multi-angle structural torque and ultimate pulling force of 80 thousand pounds. The tower foot/iron column is fixed on the steel support composed of multiple spiral anchors or multiple spiral anchors are combined together on the concrete pouring platform to ensure the stability of the whole tower body.
Screw anchor vs. concrete poured screw anchor
- Features -
