Further, the outer wall of the vertical sieve tube is wrapped with a permeable filter membrane.
Further, the driving member is a motor.
Furthermore, the water outlet pipe is communicated with a water suction pump.
Further, the vertical sieve tube is a stainless steel tube.
The utility model has the advantages that: after the vertical sieve tube is buried in the soft soil layer to be treated, the vacuum pump extracts air inside the vertical sieve tube, so that the soft soil layer to be treated is subjected to drainage consolidation under vacuum load prepressing, the produced water enters the inside of the vertical sieve tube through sieve pores of the vertical sieve tube, when the entering water level rises, the vacuum pump stops working when the negative pressure transmission is reduced, then the driving piece drives the helical blade to rotate, so that the water flow is axially pushed by the helical blade, the water flow is discharged from the top end of the vertical sieve tube through the water outlet pipe, so that the water level in the vertical sieve tube is reduced, then the vacuum pump continues to operate, the effect of negative pressure transmission is ensured, the drainage consolidation speed of the soft soil foundation is improved, and further the effective consolidation depth of.
