A method for pressure pipe drilling a pipe comprising an exterior layer and an interior layer, the method comprising internally lining the pipe with a fluid-tight sheath; drilling a first cavity through the exterior layer until exposing the interior layer; injecting a sealant into the first cavity; and drilling a second cavity within the first cavity through the interior layer and the fluid-tight sheath.

Method and system for pressure pipe drilling cement-mortar lined and coated steel cylinders

A structural liner for reinforcing existing underground water conduits to resist earthquakes and landslides adapted for insertion into underground water conduits without having to excavate are disclosed. The reinforcement structural device consists of a seamless woven tubular sheath impregnated with a hardening resin which is adapted for insertion into a network of underground water conduits without the need to excavate. The seamless woven tubular sheath consists of continuous longitudinal fiber warp yarn providing tensile strength along the longitudinal axis of the woven tubular sheath and circumferential fiber filling yarn providing tensile strength around the wall of the woven tubular sheath.

Seismic reinforced underground water conduit

A plug for a tubular service entrance of a conduit, wherein the plug includes a core body having a central hollow channel extending from a first end to second end of the core body; at least one flexible fin extending radially outwardly from the core body and having an outer diameter greater than the inner diameter of the tubular service entrance so that the plug is adapted to fit tightly into the tubular service entrance, and wherein the at least one flexible fin is deformable to adapt to the shape of the service entrance and apply a lateral force against the inner diameter of the service entrance. A plug dispensing magazine for storing and dispensing service entrance plugs to be service entrances of a conduit prior to installation of a liner in the conduit and a method of sealing the service entrances.
