Description
Technical Field
The utility model relates to a foundation engineering and geotechnical engineering field specifically are a rear-mounted soil pressure cell's installation device.
Background
In the field of geotechnical engineering, not only the soil pressure directly acting on a building structure or a supporting structure needs to be known in geotechnical investigation design, but also the in-situ soil pressure at different positions in the soil body needs to be known in some scientific researches. The in-situ soil pressure and the soil pressure acting on the structure are obtained mainly through indirect theoretical calculation at present. And directly obtaining the actual soil pressure at the determined position, and testing by adopting a soil pressure cell. In the conventional soil pressure test, after construction and excavation, a soil pressure box is buried in the soil facing surface of a building enclosure, or the soil pressure box is installed at a required position by adopting an active driving method and the like. The former is front-mounted, and the problems that the sensor is damaged and the cable is broken and the like are difficult to recover are easily caused in the foundation construction process. This method of installation has been a difficult and painful point for field soil pressure testing.
