Description

Technical Field

[0001] The utility model relates to the technical field of soil vacuum degree monitoring under a vacuum preloading sealing membrane, in particular to a soil vacuum degree monitoring device under a vacuum preloading sealing membrane. Background Art

[0002] Vacuum preloading is a commonly used foundation treatment technology. By laying a sealing membrane above the soil and extracting the air, negative pressure is formed, which prompts the water in the soil to be discharged, thereby accelerating the consolidation and strength improvement of the soil. The soil vacuum degree monitoring device under the vacuum preloading sealing membrane is an indispensable component of vacuum preloading technology. It provides important data support for the project by accurately monitoring the vacuum degree, ensuring the quality and safety of the foundation treatment. It is more common in foundation treatment.

[0003] Existing technologies include a utility model with announcement number CN216865093U, which discloses a vacuum monitoring device for vacuum preloading foundation treatment under a vacuum membrane. The patent includes a vacuum pressure tube, a vacuum probe, and a data cable connected to the vacuum probe. The vacuum probe is placed in the vacuum pressure tube, and the vacuum pressure tube is inserted into the vacuum soil. The end of the vacuum pressure tube is closed, and there are at least two vacuum probes. Holes are opened at the position where the vacuum probes extend into the vacuum pressure tube. The hole section of the vacuum pressure tube is filled with a gravel layer, and the unopened section of the vacuum pressure tube is filled with a sealing layer. In the utility model, holes are set at different heights in the vacuum pressure tube, and the vacuum probes are respectively inserted into the hole sections at the corresponding positions. This allows the changes in the soil vacuum degree at different depths as the preloading treatment progresses, facilitating real-time control of the quality of vacuum preloading construction.
