为了提高动力触探试验中记录锤击数的准确性,避免人工记数出现的差错,我们结合DTZ-8型动力触探钻机的研制,对锤击记数自动化进行了探讨,研制成一种电子计数器装置。实践表明,该计数器操作方便,计数准确,显示清晰,工作稳定可靠。电子计数器安装在钻机的操纵台上,其外形如照片所示。为方便记录,该装置由左、右两组计数
In order to improve the accuracy of the recorded number of hits in the power penetration test and avoid the errors in the manual counting, we developed the automatic hammering count test in combination with the development of the DTZ-8 type dynamic exploration drilling rig and developed an electronic Counter device. Practice shows that the counter is easy to operate, accurate counting, display clear, stable and reliable. The electronic counter is mounted on the rig’s console as shown in the photo. For the convenience of recording, the device counts left and right groups
