Abstract
An apparatus and method for inspecting sewerage pipes, comprising in combination with a first mobile pipe vehicle, a gas sensor vehicle for detecting pipe ambient gas. The combination includes an interface cable conveying power and operably connecting the combination to a control station positioned outside the pipe, a second vehicle having a support frame connected to the first mobile pipe vehicle, a gas sensor positioned on the second vehicle support frame and connected to the interface cable for sensing pipe ambient gas level, and a transceiver communicating with the gas sensor and connected to the interface cable for therethrough communicating with the control station. The second vehicle is preferably connected to the first mobile pipe vehicle by the interface cable and is thereby towed in the pipe.
