Construction method for five-shaft cement mixing pile without squeezing soil
The invention relates to a construction method for a five-shaft cement mixing pile without soil compaction; a machine used in the construction method is a non-squeezing five-shaft cement mixing machine (namely, FCW-A construction machine). In the machine, five drill pipes are arranged side by side and comprise ordinary polished drill pipes and small-margin threaded drill pipes. The five drill pipes can be combined freely by the two kinds of drill pipes according to rules and construction requirements. During construction, the small-margin threaded drill pipes rotate forward to lift soil to the ground so as to adjust the imbalance of soil pressure in the pile. The construction method is adopted to construct the cement mixing pile and has the advantages of being rapid in pile formation speed, uniform in mixing, high in strength, strong in anti-permeation capacity, environment-friendly and green and the like.
