The invention discloses a deep
soil mass load deformation test standard
penetrometer successively including from top to bottom a guide rod, a hammer
cushion, a sounding rod and a hydraulic penetrationsystem, a displacement sensor is arranged in the hydraulic penetration
system, the guide rod is sheathed with a pilereing hammer, the telescopic end of the hydraulic penetration
system is connected with a standard
penetrometer body, and the invention also discloses an operation method of the deep
soil mass load deformation test standard
penetrometer. The deep
soil mass load deformation test standard penetrometer and the operation method thereof solve the shortcomings that domestic
standard penetration test systems cannot evaluate underground soil
mass load deformation rules and static parameters, has the advantages of simple structure, good
quality control, convenient operation, fast detection speed, high measurement efficiency, detection result accuracy and reliability, and good
repeatability, and provides a powerful testing tool for
civil engineering exploration and practice.
