The present invention discloses a soft soil foundation single-hole 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, and the air diffusion cavity body is located below the water drainage 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, thus achieving deep drainage and a drainage consolidation time of the deep soft soil foundation is shortened.

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.

Soft soil foundation porous-depth air compression drainage device and working method thereof

A groundwater level elevation measurement method is provided. A permeable cylinder is drilled at a measurement site to ensure that groundwater enters the permeable cylinder. A water inlet of an aqueduct extends below the liquid level in the cylinder, and a drainage outlet thereof is led to the ground. A stable drainage flow rate is detected, and a water level elevation at the water inlet is calculated according to the formula. An optimization method is to detect the flow rate after a stable negative pressure is introduced, and then calculate the water level elevation at the water inlet. According to the groundwater storage monitoring and measurement system of the present invention, a matrix of water level monitoring sites is laid out, groundwater level elevations at all sites and related data are measured and collected, and water storage characteristic data of a groundwater measurement space is constructed.
