Automatic simple dynamic cone penetration testing machine

摘要

The present invention ensure the accuracy of the free fall height, counted difference of penetration times, prevention of human negligence, such as clerical error, avoidance of risk, such as sandwich the finger between the hammer and knocking head, because of arm fatigue recovery a substantial break time of labor saving, automatic simple dynamic cone testing machine that can ensure a reduction in personnel by automation. The invention relates to make a simple dynamic cone testing machine to the provisions of Geotechnical Engineering Society by mounting the site of the next big five. Mounting site is one control and display sites, 2 drive site, 3 operation sites, 4a and 4b measurement sites, 5a and 5b support site, consisting of 6 data output terminal site. .BACKGROUND
