Specific by Jiangxintun cresidential building build site survey of the environmental, engineering, engineering-geological conditions, combined with building materials and engineering experience gathered here proposedCFGpile composite Foundation treatment programme of the Foundation. CFGpile designed from bearing capacity of pile and the pile spacing, and the settlement and the design of cushion, final summary of the design was its own design ideas and requirements.
