Abstract

An auger-suction type metro jet system (MJS) device for aerated and lightweight cement soil includes a multi-pipe device, an outer sleeve, an integrated device, a spiral conveyor, a reamer head, a pressure monitoring system, a mass measuring device, and a control console. The multi-pipe device integrates a backup pipe, a negative-pressure gas pipe, a hydraulic pipe, a negative-pressure water pipe, a pressure sensor wire pipe, a pressure water pipe, a backup gas pipe, a power wire pipe, and at least one grouting tremie unit. The spiral conveyor includes a shaft-type spiral conveying belt and a negative-pressure device. A construction method for foundation reinforcement construction includes: cutting soil by the reamer head; crushing gravel by a gravel crusher; transporting, by the shaft-type spiral conveying belt, a soil-water mixture to a waste liquid tank; monitoring, by the mass measuring device, a mass of the soil-water mixture discharged; and injecting equal-mass cement.
