Penetration testing has been used to measure material properties for over fifty years. Currently, it is under-utilised as a contemporary scientific and engineering tool for investigating the condition of pipes whose inner surface has been exposed to chemical attack. We describe the design, development and calibration of a portable probe which uses a penetrative strain gauge load cell to measure where the semi-solid surface starts and stops within a pipe. We also describe the results of field tests of the probe in concrete sewers, affected by internal corrosion, where the probe proved to be a fast and reliable method for collecting pipe profile information. The results indicate significant benefit in the use of penetrometers to perform concrete sewer condition assessment.
渗透测试已经被用于测量材料特性五十多年了。目前，它作为一种用于研究内部表面受到化学侵蚀的管道状况的当代科学和工程工具还未得到充分利用。我们描述了一种便携式探头的设计、开发和校准，该探头使用穿透应变计称重传感器来测量管道内半固态表面开始和停止的位置。我们还描述了探头在受内部腐蚀影响的混凝土污水管道中的现场测试结果，结果表明探头是一种快速可靠的收集管道轮廓信息的方法。结果表明，渗透计在进行混凝土污水管道状况评估方面具有显著的优势。
