STATION FOR DYNAMIC SOIL PROBING AND HAMMER THEREFOR

摘要

The claimed invention relates to the devices for geological ground surveys by a method of a dynamic probing test, in particular, for geological ground surveys by way of soil resistivity determination at a different depth. It is suggested a dynamic probing test station, comprising the interconnected probe having push rods and electronic sensing measuring system, as well as an impact device with a movable load - head and a mean of the probe extraction out of the groundThe impact device represents a hammer mounted at a guide support, comprising a hydraulic motor executed as being capable of driving a chain gear mechanism, placed in the jacket and is executed being capable of cut-off kinematical connection with the head, executed as being capable of vertical hammer blow transfer to a foot bearing and further to the probe push rod, mounted in the foot bearing. The measuring system comprises a probe penetration depth measuring transducer, informatively connected with at least one penetration depth sensor, and a hammer head shock pick-up into the electric impulses, informatively connected with the probe penetration depth measuring transducer, mechanically rigidly connected with the guide support and kinematically connected with a hammer lift control lever, the probe penetration depth measuring transducer and the hammer head shock pick-up into the electric impulses being connected through a distribution block with a programmable dynamic probing test register.2
