The packer seen here is for 36`` mainlines. The assembly can be rolled in the pipe and is composed of a jacking post, curved stainless steel plate with closed cell rubber foam, two grout ports, one liquid filled sensor line, and a threaded orifice to install lateral groutingplugs. Pillow bearings allow the jacking post to be rotated cw & ccw, in order for the lateralplug to be physically inserted into the lateral and inflated. A hydraulic ram can be used to press the plate against the inside surface of the mainline pipe. The tap is then isolated fromthe pipe and the lateral connection can be injected.
