摘要
土壤渗透性测试需要对水位进行时间序列测量,以确定系统损失,包括渗透和蒸发。实验室流量测量由 ASTM International、ISO 或 UNE 等国际法规进行标准化,但现场测量的描述并不完善,在某些情况下可能需要对测试条件进行定义和说明。土工合成粘土衬垫(GCL)产品就属于这种情况,其渗透性是通过使用标准测试方法 D 5887-04 中定义的柔性壁渗透仪进行实验室测量来评估的。这种方法无法评估此类产品在现场的性能,因此无法保证它们能够用于垃圾填埋场衬垫覆盖层的修复。为此,我们确定了在密闭钢圈中进行现场测试的方法,并开发了一种实时超声波物联网设备,用于评估一段时间内的水流失情况。我们在马略卡岛(西班牙)应用了该测试方法,结果对垃圾填埋场覆盖层修复方案的质量进行了评估,开展了相应的土木工程,并为今后在不同材料和条件下进行土壤渗透性测试的实地测量奠定了基础。
Real-time ultrasonic water level IoT sensor for in-situ soil permeability testing
Soil permeability tests require a time series of water level measurements to determine system losses, including both infiltration and evaporation. Laboratory measurements of flow are standardised by international regulations such as ASTM International, ISO or UNE, but field measurements are not as well described and in some cases may require definition and specification of test conditions. This is the case for geosynthetic clay liner (GCL) products, where permeability is assessed by a laboratory measurement using a flexible wall permeameter as defined in standard test method D 5887-04. This method is not able to evaluate the performance of such products in the field and therefore cannot guarantee their ability to be used for the repair of landfill liner overlays. For this reason, we have defined a field test in a confined steel ring and developed a real-time ultrasonic IoT device to evaluate water losses over a period of time. The test method was applied in Mallorca (Spain) and as a result the quality of a landfill cover repair solution was evaluated, the corresponding civil works were carried out and the basis for future field measurements of soil permeability tests on different materials and conditions was established.

期刊介绍:
HardwareX is an open access journal established to promote free and open source designing, building and customizing of scientific infrastructure (hardware). HardwareX aims to recognize researchers for the time and effort in developing scientific infrastructure while providing end-users with sufficient information to replicate and validate the advances presented. HardwareX is open to input from all scientific, technological and medical disciplines. Scientific infrastructure will be interpreted in the broadest sense. Including hardware modifications to existing infrastructure, sensors and tools that perform measurements and other functions outside of the traditional lab setting (such as wearables, air/water quality sensors, and low cost alternatives to existing tools), and the creation of wholly new tools for either standard or novel laboratory tasks. Authors are encouraged to submit hardware developments that address all aspects of science, not only the final measurement, for example, enhancements in sample preparation and handling, user safety, and quality control. The use of distributed digital manufacturing strategies (e.g. 3-D printing) is encouraged. All designs must be submitted under an open hardware license.
