Vacuum degree monitoring device and method of vacuum-prepressed soil mass

The invention discloses a vacuum degree monitoring device and method of vacuum-prepressed soil mass. A vacuum probe wrapped by geotechnical cloth is placed in the vacuum-prepressed soil mass or undera vacuum-prepressed sealing film; a vacuum pressure gauge is fixed on a concrete fixed plate; the vacuum pressure gauge is connected with the vacuum probe through a pressure pipe, the equivalent observation of the vacuum degree between the soil mass and the vacuum probe is realized through vacuum probes buried in the soil mass with different depths, and the requirement on the vacuum degree real-time monitoring by the vacuum-prepressed foundation treatment is satisfied. The device disclosed by the invention is simple and reliable, convenient for operation, convenient for manufacturing principleand material, safe and reliable; the soil mass vacuum degree monitoring efficiency and the reliability are greatly improved, and the safety monitoring cost is greatly reduced, and the device can be extensively applied to the
