Methods and systems are disclosed for laying trenchless pipes under ground. In these methods strips of fabrics saturated with resin are helically or non-helically wrapped around desired shape mandrels that are located near an entrance to an underground tunnel or an old pipe, and the partially cured pipes are lowered into the tunnel or the old pipe and is pulled by chain or cable from the other side of the tunnel or the old pipe to line the tunnel and the old pipe. One or more kinds of sensors or gauges may also be attached to or embedded in the fabrics to monitor various aspects of the pipe or the content of the pipe.
