    Abstract: The invention relates to an apparatus and method of freezing a section of fluid-filled pipeline. The apparatus disclosed herein consists of a cylindrical body which is pumped down the pipeline to the section to be frozen. The body so positioned reduces the volume of fluid required to be frozen while shaped discs attached to each end of the body prevents fluid circulation. Also disclosed is a tank positioned around the exterior of the pipe line which contains refrigerants to freeze the fluid within the pipeline.

    Abstract: Apparatus for injecting grouting materials under pressure into a wall structure through a hole. A grouting nozzle is attached by a hose to a pump. A tube of elastic material is inserted in the cylindrical drilled hole in the wall. The nozzle has a tapered shank portion with screw threads that have a long axial face and a short radial face. After the tube is placed in the hole, the nozzle is inserted in the tube and rotated until the nozzle is secured in the hole. The pump can then be operated to inject fluid under pressure through the nozzle to the interior of the wall structure. The nozzle can be easily removed from the hole unscrewing the nozzle relative to the tube.
