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渗透仪的新型膜入口。圆锥渗透仪现在被用来了解修复地点的现场地质情况。配备化学传感器的圆锥渗透仪将使目前所需的地球物理研究与化学调查相结合，从而降低现场补救成本。这将最大限度地减少所需的昂贵油井数量。此外，化学分析现在通常在实验室进行，花费巨大，将在现场进行。现场工程师将能够以最低成本实时做出补救决定。最近对圆锥体渗透仪的测量工作使用了大型复杂的激光系统，这些系统通过光缆将光传输到地下，并将信号返回地面进行分析。这些系统的价格可能高达25万美元。这项研究将开发一种用于圆锥渗透仪的薄膜入口，这将使使用廉价的现场化学气体传感器测量圆锥穿透仪成为可能，预计系统成本不到10,000美元。第一阶段的目标是在实验室中用在修复地点发现的典型化学物质来演示膜入口。整个计划的目标是在两个补救地点建立并演示一个完全运行的锥形贯入仪系统。

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.
