Advantages of spiral pile

　　The stress of traditional ground pile is not only related to the soil layout load, data strength, layout mode, rigidity of foundation pile and other factors, but also restricted by the ever-changing soil quality of foundation, forming a very complex system. However, there is no need to think about these factors for spiral ground pile. The spiral ground pile is simple in layout, low in cost, fast in construction, no need of cement pouring and pollution prevention In addition, the spiral pile is also widely used in the construction of simple house base, tent and fence.

　　It has been proved by long-time engineering construction that the size of the ultimate bearing capacity of the spiral ground pile is closely related to the pile type parameters. Under the effect of horizontal load or oblique compressive load, the ultimate bearing capacity of the spiral ground pile increases with the addition of the blade pitch width ratio; under the effect of oblique tensile load, the ultimate bearing capacity of the spiral ground pile decreases with the increase of the blade pitch width ratio.
