In order to resolve these problems, many measures are raised, and the appearance of the new environment-friendly down tapered foundation is an important breakthrough, it is product of gravel ring wall foundation and environmental protection technology, it’s outstanding feature is that the outer zone of the foundation is higher than the inner zone, so the bottom plate is like an down taper.
