A tool assembly is provided for working on underground pipes, through a small hole at the pipe surface, by means of an elongate handle member that reaches into the hole, and has a coupling at the lower end thereof, whereby various ones of selected tools may be quickly connected to and disconnected from the lower end of the handle member, by means of a universal coupling, and whereby the tools can be pneumatically driven from above ground.

Tool assembly with universal coupling for various tools, for work on underground pipes

A tool assembly and a process for using it is provided, wherein a single elongate handle member may be used, through a small hole at the ground surface, to reach underground pipes for installing different sized strap 'T' couplings on different sized pipes, and for driving sleeve members associated with said strap 'T' couplings, pneumatically, from above ground, to engage pipes at various locations below ground.

Apparatus and process for installing 'T' couplings on underground pipe

A self-locking, high-pressure stopper is disclosed. Also disclosed is a method of using the stopper. The stopper allows a branch pipe to be plugged from above ground using an elongated insertion tool. The self-locking stopper of the present invention includes a body having O-ring seals that is inserted into the branch pipe that is to be plugged. The self-locking stopper has outwardly biased locking tabs that are provided to engage a shoulder or step in the branching pipe in order to prevent the stopper from being pulled out, or pushed out by fluid pressure, once it is in place. The stopper system also includes a flanged insertion pipe used for inserting the stopper into the branch pipe. The stopper also has an adapter for engagement by an insertion tool that allows a user to insert the stopper from above ground.

Self-locking, high pressure service stopper

The method and two devices provide for the underground connection of pipe with minimal disruption of the surrounding landscape. A main pipe is cleaned by a surface preparation tool designed to access the main pipe through a small hole. An adaptor is attached to a second pipe, and then placed in a clamping device designed to access the main pipe and clamp the adaptor thereto through the small hole. Electricity is passed through the adaptor, thereby softening the plastic so that this softening and the pressure of the clamp secures the adaptor to the main pipe. The main pipe is then pierced by the adaptor's tapping tee.

Method and apparatus for underground connection of pipe

The present invention is a lance for removing dirt or other substances from an underground hole, by the use of air and water under high pressure. The water is used as an abrading material or lance to loosen dirt in a hole or to pick or chip off substances which are attached to a pipe. A limited amount of water is used during the operation of the apparatus, to prevent the formation of wet mud.
