灌浆记录仪校验方法研究

灌浆记录仪是实时测量和记录水泥灌浆施工进程参数的仪器，是实现灌浆施工过程控制、保证工程质量的重要手段，已在我国水利水电及相关工程的基础灌浆处理中获得广泛应用。该仪器目前尚未纳入法定计量监督管理，产品质量和计量特性评定缺乏统一标准，因而影响了仪器应用效果和产品市场健康发展。结合灌浆工程实际，在参照相关标准规范的基础上，初步提出灌浆记录仪的校验内容、原则和方法，为灌浆记录仪校验标准制定提供了基本思路。

Methods of Grouting Recorder Calibration

Grouting recorder is an instrument to measure and record the real-time parameters of cement grouting process. It's an important means to control grouting process and to ensure  project quality. It has been widely used in the foundation grouting in China's water conservancy and hydropower engineering. However, the instrument is not yet included in the supervision and management of China's legal metrology, hence the product quality and the metrological characteristics are in lack of single standard, which affects the application effect and the sound development of the product market. On the basis of related standards and regulations, we proposed the contents, principles, and methods of grouting recorder calibration in line with engineering practices. The research provided basic idea for  formulating  calibration standard for grouting recorder.
