Abstract
The present invention provides an apparatus and method for repairing a manhole. The wall of the manhole is lined with a liner to form a new wall. The liner includes a resin that cures to form the new wall that is similar to the repaired wall. Embedded in the liner is a wireless data transfer mechanism that includes a transmitter, such as a radio-frequency identification (RFID). The RFID transmits identification information about the liner or the repaired wall. The transmitter may be capable of data entry in the field or may be otherwise field-programmable and further capable of transmitting at least one physical characteristic. Examples of physical characteristics may include temperature, pressure, chemical reactions, flow within the manhole, and the like. Additional transmitters may be used along the length of the manhole to determine characteristics at multiple locations, with each additional transmitter including the same or different sensors.
