Waterproofing monitoring system
This is an equipment system for automated monitoring of the waterproofing leak tightness in real time. Its chief elements are:
MPLE cable – laid down into the ground/concrete under the waterproofing into lines purposely combined into channels at a distance of 5 - 8 metres away from each other and covering the entire area. It is intended for controlling the waterproofing leak tightness at all times. Inside the cable there are up to 40 sensors located at a distance of 5 - 8 metres from each other.
Connection and control board – for connection of all the wires, as well connecting to the information collection and processing station.
Information collection and processing station – intended for analogue to digital conversion and transmission to the operator panel via the internet using a LAN/GPRS connection.
Software – integrated into a separate computer for monitoring the waterproofing; converts the incoming digital signal from the information collection and processing station into a graphical format, designating precise coordinates and the location of the damaged area (if there is one) on the user UI.
Fig. 1 displays the general layout of laying the system. Therefore, during construction it is necessary to lay down the MPLE cable and ensure its connection to the control board.
Before laying down, diagnostics are run on the MPLE cable and the sensor functioning is tested.
During the design stage, each cable and sensor within is assigned a personal number, visible on the diagram.
After the cable is tested, it is laid down into the ground/concrete under the waterproofing. A network of sensors is formed under the waterproofing. A pulsing (at designated intervals) electrical current is applied to both terminal electrodes, located on both sides of the waterproofing. If damage occurs, an electrical connection is made and the sensors measure the distance to the damaged area, supplying precise coordinates. The information collection and processing station routes the data to the operator's computer, in which the user interface displays the precise coordinates of the damaged area, as shown on the screen.
The system works autonomously, without direct operator participation. In the case that waterproofing is damaged, the system sends out an SMS and e-mail notifications, allowing for an immediate response.
