The SOIMON project will develop an in-situ soil sensing system that is deployed in a sonic drill machine. Thecomplete system/ bore pipes are going to be equipped with condition monitoring sensors in order to increase life time, enhance drilling time, cost and reliability of the soil monitoring process. The overall aim of the SOIMON project is to develop an advanced and reliable in-situ investigation method for identifying and characterising pollution in a wider type of terrains. The concept integrates:
- A solid probe using advanced sensor technologies for organic compound analysis combined with the anti-vibration control system in one of the bore pipes.
- Condition Monitoring sensors based on acoustic emission (AE) and vibration analysis and techniques.
The generated signals are transmitted to the central computer unit by means of wireless nodes communication. The results are then accessed remotely via a software application. The monitoring system can also be connected to the internet if there is internet hub available at the inspected site. The SOIMON system will be using sophisticated state of the art computational analysis to enable location and sizing of cracks and corrosion with sufficient accuracy using conventional methods.
The bore-pipes integrity will be fully checked using vibration based techniques and sensors and the data will be fed to the AVC tool in order to attenuate their impact at the first bore-pipe where the analytical/ radiometric sensors case is located. Furthermore, the need to be at the site for sampling presents the inspector with a potentially hazardous environment however, the vibration damping and analysis techniques developed in this project are either permanently or semi-permanently installed and can be remotely operated therefore there is no need for the operator to be on site. In addition, the downtime and costs associated will be reduced by analysing samples on site and in live time, which will provide a fast set of data for rapid decision making of soil treatment.
In parallel to this development, novel soil sensing techniques with improved sensitivity for organic compound analysis will be integrated with the objective of increasing sensitivity and reducing the volume occupied by peripheral equipment. The sensors will be tested and assessed throughout the detection of the different chemical compounds and their concentration.
