Zusammenfassung:Disclosed are a construction method and a construction system for eliminating sand liquefaction. The construction system includes a first drilling rod, a pneumatic down-the-hole (DTH) hammer installed on the first drilling rod, an air compressor drivingly connected with the pneumatic DTH hammer, a driving motor drivingly connected with the first drilling rod and a high-pressure pump connected with the first drilling rod; and the construction method includes following steps: measuring the ground to be constructed to determine the pile position to be constructed; controlling the air compressor to drive the pneumatic DTH hammer to drill holes in the pile position to be constructed, controlling the driving motor to drive the first drilling rod to rotate around an axis in an up-down direction, and controlling the high-pressure pump to spray the cement slurry toward a circumferential side of the first drilling rod.
