Abstract
A trench-less plug assembly having a fluid release element, further including: a top retaining ring, a bottom retaining ring, a plurality of rods vertically connecting the top retaining ring to the bottom retaining ring. A retaining plug is adapted to traverse vertically along the plurality of rods, and a main fitting adapted for receiving the bottom retaining ring. A gasket is disposed between the main fitting and the retaining plug. The plurality of rods engage the retaining plug with threads, whereby the retaining plug is positioned vertically between the top retaining ring and the bottom retaining ring by rotational movement of the retaining plug. The main fitting is adapted to attach to a main pipeline, and the main fitting is adapted to receive a riser enclosing the fluid release element. In one example, the main fitting attaches to a main pipeline using a saddle.
