Description
Technical field
This utility model belongs to soil pressure technical field of measurement and test, more particularly to a kind of telescopic earth pressure gauge.
Background technology
Soil pressure is that the soil body acts on works or the power on structures, is reflection roadbed, ground, basis etc. and top
One important parameter of works or structure working condition, soil pressure variation characteristic not only has theoretical research and practice meaning
Justice, also with instruct engineering research, design, construction, operation maintenance etc. act on.
The test device commonly used in soil pressure test mainly has a type vibration wire piezometer, and type vibration wire piezometer is mainly by carrying on the back
The composition such as plate, tablet, vibratory string and exciting solenoid, signal-transmitting cable, with flatness, microstrain, close contact
The characteristics of property.But in the soil bodys such as flexible roadbed, ground, high roadbed, using vibratory stress gauge test soil pressure change
When, still there is generation shelling, the defects such as soil body moderate finite deformation cannot be adapted to.
Utility model content
