Cone Penetrometer Membrane Inlet

这个小型企业创新研究项目将展示一种用于土壤和地下水化学检测的锥形流量计的新型膜入口。 现在使用锥形磁流变仪来了解补救现场的地质情况。配备有化学传感器的锥孔流量计将通过允许将当前所需的地球物理研究与化学调查相结合来降低现场补救成本。这将使所需的昂贵的威尔斯井的数量最小化。此外，化学分析，现在例行在实验室进行，费用很高，将在外地进行。现场工程师将能够以最低的成本在真实的时间内做出补救决策。最近对仪器化的锥形流量计的努力已经使用了大型复杂的激光系统，该激光系统通过光纤电缆将光发送到地下并将信号返回到地面进行分析。这些系统可能需要25万美元。这项研究将开发一种用于锥形流量计的膜入口，这将使人们有可能用廉价的、原位的化学气相传感器对锥形流量计进行仪表化，预计系统成本低于10，000美元。第一阶段的目标是在实验室中展示一种膜入口，并在补救现场发现典型的化学品。总体计划目标是在两个补救现场建立和演示一个全面运行的锥形流量计系统。

This Small Business Innovation Research project will demonstrate a novel membrane inlet for cone penetrometers instrumented for chemical detection in soil and groundwater. Cone penetrometers are now used to understand site geology at remediation sites. Cone penetrometers equipped with chemical sensors will reduce site remediation costs by allowing the currently required geophysical stuty to be combined with a chemical survey. This will minimize the number of expensive wells required. Further, chemical analyses, now routinely done in the laboratory at significant expense, will be done in the field. Field engineers will be able to make remediation decisions in real time at minimum cost. Recent efforts to instrument cone penetrometers have used large sophisticated laser systems which send light underground through fiber optic cable and return the signal to the surface for analysis. These systems can cost $250,000. This research will develop a membrane inlet for cone penetrometers which will make it possible to instrument a cone penetrometer with inexpensive, in-situ, chemical vapor sensors with a projected system cost of under $10,000. The phase I objective is to demonstrate a membrane inlet in the laboratory with typical chemicals found in remediation sites. The overall program objective is to built and demonstrate a fully operational cone penetrometer system at two remediation sites.
