井点降水管成活率测试仪的研制与应用

摘要

用于检测井点降水管是否成活，采用压电式加速度传感器，以振动测量作为基本设计原理，克服环境干扰等因素，研制和开发了高灵敏度，低噪声的井点降水管成活率测试仪器。实用效果很好。%The mesuring instrument is applied for detecting the pipes for falling-off well's water level. Takingvibration measurement as basic design theory, using acceleration sensor, the instrument has high sensitivityand low noise and can be used for mesuring the surviving possibility of the pipes to fall well's water. It has agood practical effect.
