What's the difference between a rooted pile and a rigid pile?

I haven't heard of rigid pile, but embedded pile is a new patented construction technology, called static drilling and grounding pretensioned prestressed concrete bamboo pile (hereinafter referred to as static drilling and grounding bamboo pile). Compared with the traditional construction method, its novelty lies in the construction method of burying the precast pile in the pile hole by using the self-weight of the pile body after drilling, which has the advantages of both the buried construction method and the factory production of the precast pile, and the grouting method is adopted at the pile end and around the pile to carry out the bottom expansion treatment, which has the advantages of mixing pile and bottom expansion pile. It is a new technology which combines the advantages of various construction methods.
