Zusammenfassung:The invention discloses a grout and powder variable automatic control mixing pile construction method and construction equipment, and relates to the field of civil construction. The construction equipment is connected with grout storage equipment and dry powder cement and compressed air storage equipment and comprises drill rods, cement grout channels, dry powder cement and compressed air channels, a grout outlet, a dry powder cement outlet, a grout conveying pipe, a dry powder cement and compressed air conveying pipe and a control main machine. Due to the fact that the cement grout channel and the dry powder cement and compressed air channel are arranged in each drill rod, and are used for conveying wet and dry media, dry and wet medium switching can be achieved, multiple purposes can beachieved, different types of media are adopted in different soil layers, the use amount of the media is controlled, so that the pile forming quality of mixing piles is improved.
