At present, China's energy pile technology is still underdeveloped, with such of its problems as small project scales, complicated construction conditions, restricted core technology, and high development costs. Combining the actual conditions of pile foundations in Ningbo and the research in Ground Source Heat Pump (GSHP) technology, a new energy-pile technology based on static drill rooted nodular piles is proposed. The advantage of this technology is that in the course of planting, a pile sinks by its own weight and pulls the ground source heat pump on its hook down to the depths where the pile bottom is, thus saving the trouble of manual planting of the pumps and cutting the construction cost. Moreover, the pump does not need to be divided into sections and therefore cuts down the interference with the planting of the piles. The research and development of the technology and its application are introduced in the paper.
