What Does Spacer Mean?
A spacer is a device used to create or maintain space between two objects. It is used to connect a jacking thrust ring to a pipe, for example, or to separate and stabilize multiple pipes in a conduit. Trenchless operators use a wide variety of devices during construction, and spacers are useful tools in pipe installation.
Trenchlesspedia Explains Spacer
Pipe jacking is one area of trenchless construction that may require spacers. The use of spacers is optional with jacking thrust rings. When used, they are installed between the thrust ring and the pipe or casing. Mechanical spacers can extend the thrust of the pipe jack.
Spacers can take many forms. Casing spacers are used to keep space between pipes and pipe casings. These are used to center and stabilize pipes during installation. Pipe spacers separate multiple pipes that run through a conduit. These can be standard or customized to fit. Pipe spacers can be used to support pipes during installation in trenchless construction operations.
