It is additionally provided with the slide plate 3 sliding up and down along slide bar 4 between gripper shoe 1；Described slide plate 3 is arranged on the outfan of hydraulic cylinder 2, fixture
9 upper ends being arranged on slide plate 3, increase the stationarity of test.
During test：First reinforced earth test specimen 7 is placed on upper backup pad 5, and it is upper so that the muscle body 8 in reinforced earth test specimen 7 is passed through
Through hole in gripper shoe 5, then passes through two clamping cylinders 6 fixing；Driving hydraulic cylinder 2 drives slide plate 3 to move upwardly through again
Fixture 9 connects the muscle body 8 in reinforced earth test specimen 7, and last driving hydraulic cylinder 2 drives fixture 9 to move down measurement muscle body 8 and the soil body
Between frictional force.
Due to the utilization of technique scheme, this utility model compared with prior art has following advantages：
Pull-out test function described in the utility model quickly measures the frictional behavior between the soil body and muscle body, and structure letter
List, easily fabricated and use.
The above is only concrete application example of the present utility model, any limit is not constituted to protection domain of the present utility model
System.All employing equivalents or equivalence replacement and the technical scheme that formed, all fall within this utility model rights protection scope it
Interior.
