Vacuum preloading soft soil foundation treatment method
The invention discloses a vacuum preloading soft soil foundation treatment method. The vacuum preloading soft soil foundation treatment method includes the steps that at least three different-processing-depth layers in a to-be-treated soft soil foundation is each provided with at least three vertical vacuum pressure observation holes, pressure measurement pipes are arranged in the vacuum pressure observation holes, vacuum manometers are connected to the upper ends of the pressure measurement pipes, and ground surface settlement observation points are arranged at the positions, close to hole openings of the vacuum pressure observation holes, of the surface of the to-be-treated soft soil foundation, an information construction method is achieved, and construction decision making is more scientific and reasonable; as an intermittent type vacuum preloading control state is started after the stratum vacuum pressure field formation stage and the ground surface rapid sedimentation stage are finished and the stable sedimentation stage is started, and the intermittent pump stopping and pump starting circulation operation is repeatedly carried out, the vacuum drainage consolidation efficiency can be improved, the construction period is shortened, power consumption can be reduced in the same construction period, and meanwhile foundation softening after vacuum preloading treatment is reduced.
