Automatic counting device and method for standard penetration test
The invention provides an automatic counting device and method for a standard penetration test, and the device comprises a penetration rod which has a preset length, and comprises a penetration end which is driven into a soil body by a piercing hammer, and a free end which is far away from the soil body; the frame body is fixed at the free end of the sounding rod by taking the first side surface as a mounting surface; the free end, close to the sounding rod, of the vibration sensor is fixed in the first side face of the frame body, and the vibration sensor is used for detecting the vibration strength of the sounding rod when the sounding rod vibrates; the signal processing module is close to the vibration sensor and is fixed in the second side face of the frame body, a preset vibration threshold value is set in the signal processing module, and the signal processing module is used for comparing the vibration intensity detected in the vibration sensor with the preset vibration threshold value, automatically recording the vibration intensity and the number of times of vibration which are larger than the preset vibration threshold value and outputting the vibration intensity and the number of times of vibration. And recording the vibration times when the sounding rod is hit into the soil body by the preset depth as the standard penetration number N. According to the invention, the accuracy of standard penetration test results is effectively improved.
本申请提供一种标准贯入试验自动计数装置及方法,包括:触探杆,具有预设长度,包括被穿心锤击入土体的触探端和远离土体的自由端;框体,以第一侧面为安装面固定在所述触探杆的自由端;震动传感器,靠近所述触探杆的自由端固定在所述框体的第一侧面内,所述震动传感器用于检测所述触探杆在发生震荡时的震动强度;信号处理模块,靠近所述震动传感器固定在所述框体的第二侧面内,所述信号处理模块内设预设震动阈值,用于将震动传感器内检测到的震动强度与预设震动阈值对比,自动记录下大于预设震动阈值的震动强度和震动次数,并将触探杆被击入土体预设深度时的震动次数记录为标准贯入击数N。本申请有效提高标准贯入试验结果的准确性。
