Abstract
The present invention discloses a soft soil foundation porous-depth air compression drainage device and working method thereof, comprising an air compression pipe and a water drainage pipe. A water drainage cavity body and an air diffusion cavity body are buried respectively in a soft soil foundation; the drainage cavity bodies are disposed around the air diffusion cavity body. Connecting to the air diffusion cavity body, the air compression pipe protrudes out of ground surface along a vertical direction of the soft soil foundation and communicates with an inflation pump; connecting to the water drainage cavity body, one end of the water drainage pipe protrudes to the bottom of the water drainage cavity body, and the other end protrudes out of the ground surface along the vertical direction of the soft soil foundation, thus achieving deep drainage and a drainage consolidation time of the deep soft soil foundation is shortened.
