installation

The first step in an HDD installation is to drill a pilot hole, a small diameter borehole that will guide the rest of the project.

The final reaming is combined with the installation of the pipeline.

The problem with hammered piles is that the dynamic loading they undergo during installation is different from the static loading they see once in service.

Next, a protective layer of wire called skid wire is spiralled around each one to protect the paper from damage and allow for easy sliding along the pipe during installation.
