[0016] The utility model belongs to the field of environmentally friendly construction of power tower and communication tower foundation. In deserts, wetlands, forests, grasslands and other places, due to ecological protection, environmental emissions, transportation difficulties, and difficulties in large-scale machinery entering, many factors have caused the on-site iron tower construction to adopt the original digging, drilling, large excavation and other forms of traditional construction methods that do not meet environmental protection requirements and ecological protection requirements, especially in the case of ultra-high voltage, long-distance lines, etc., when the force calculation meets the requirements, spiral ground piles are used. The spiral ground piles adopt a central steel pipe plus a spiral wing plate structure and a bottom pointed head. The diameter and thickness of the steel pipe, the thickness and width of the wing plate are related to the force parameter bearing capacity and the depth. The ground piles can be extended in sections according to the depth requirements. The bottom section is generally 3-8 meters for the spiral section, and the middle is extended as needed. Connecting holes are set around the steel pipe at the extension point for plug-in bolt connection. The upper section adopts the method of welding nails and the top welding threaded steel mesh. The mesh can be connected to the upper section by bolts at multiple points to facilitate the casting of the concrete base into a whole. The number of spiral piles can be arranged at multiple points according to the force requirements, site conditions, and geological conditions. Deepening the arrangement reduces the number and area occupied. The cap is a combination of the integrity of the spiral pile and the foundation anchor bolts. There are welded nails and meshes on the top of the spiral steel pipe pile. There is a threaded steel skeleton between the foundation anchor bolts and the concrete of the cap and foundation pier, and they are welded firmly to each other to form a complete whole. All parts of the spiral piles are thickened and hot-dip galvanized, and the welds reach level one. Special spiral piling equipment is used. This method and the utility model mainly reduce earth excavation, mud discharge, construction sewage discharge, occupy less space, use very little concrete, and use less large construction machinery. It saves about 40% of costs, about 70% of sites, saves more than 60% of on-site construction period, reduces emissions by more than 70%, etc. It is particularly suitable for areas with difficult access to transportation, roads and construction equipment, as well as for areas where industrial manufacturing and construction industries are underdeveloped, labor costs are high, and environmental protection requirements are particularly strict.
