Novel vacuum preloading system and treatment method for soft soil foundation treatment

The invention discloses a novel vacuum preloading system and a treatment method for soft soil foundation treatment. The novel vacuum preloading system comprises a vacuum-pumping system comprising a vertical vacuum-pumping device and a transverse vacuum-pumping device. The vertical vacuum-pumping device comprises conversion joints, drainage plates and vacuum-pumping pipes. Conversion joints outer connecting pipes extend upward, and the drainage plates penetrate through the conversion joints. The transverse vacuum-pumping device comprises a main pipe, filter pipes, hand-type joints, four-way connectors and steel wire hoses. The upper ends of the drainage plates are connected with the lower ends of the drainage plate hand-type joints. Hand-type joints outer connecting pipes are connected with the filter pipes. The four-pass connectors are connected with the hand-type joints outer connecting pipes and the steel wire hoses correspondingly. The other ends of the steel wire hoses are connected with the lateral vacuu
