Automatic collection device for hammering number in standard penetration test
The invention provides an automatic collection device for the hammering number in a standard penetration test, and belongs to the technical field of measurement of standard penetration tests. The automatic collection device comprises a standard penetration test system, an automatic recording system and an automatic detection device. The standard penetration test system comprises a piercing hammer, a pedestal, a drill rod and a tripod; the automatic recording system comprises a distance measuring alarm and a hammer count counter; and the automatic detection device comprises a photoelectric sensor detection device, a fixing system of the photoelectric sensor detection device, an ultrasonic detection device and a fixing system of the ultrasonic detection device. The automatic collection of the SPT hammering number N is used for replacing field manual visual inspection, so that the probability of missing recording and misrecording of manual recording is reduced, the in-situ test digital collection level is improved, and meanwhile, the field test efficiency and precision are further improved.
本发明提供一种标准贯入试验锤击数的自动采集装置，属于标准贯入试验的测量技术领域，其包括了标准贯入试验系统、自动记录系统与自动检测装置，其中标准贯入试验系统包括：穿心锤、垫座、钻杆、三角架；自动记录系统包括：测距报警器、锤击数计数仪；自动检测装置包括：光电传感器检测装置及其固定系统、超声波检测装置及其固定系统。利用SPT锤击数N的自动采集替代现场人工目测，降低了人为记录的漏记、误记机率，提高了原位测试数字化采集水平，同时也提升了现场测试的效率和精度。
