Mainline Installation Begins...

Before beginning work on mainline installation, Landscapes Unlimited distributes HDPE pipe to various areas of the golf course allowing them to be ready to go with pipe as they progress throughout the course.

Mainline Pipe being delivered between #4 and #5 Fairways.

After distributing enough pipe to get started, Landscapes Unlimited began working on mainline yesterday.  They are beginning between #4 and #5 Fairway, because work will cause minimal disturbance to regular play. Trenches are dug using an Astec 960 trencher and are roughly 12" wide and 28-30" deep in this section.  They are dug at this depth to ensure that there is a minimum of 24" of cover on the 4" mainline.  Depth will be adjusted for different size pipe.

After the trench is dug, Landscapes Unlimited begins laying pipe and communication wire inside the trench.  Warning tape is also laid above the pipe.  Once this is complete, they begin back filling. Back filling is done is increments of 6 inches, followed by tamping.  This process is repeated until they get back to grade.

After laying a good section of 4" mainline, Landscapes Unlimited came to the first tee in the mainline. This tee is a 4x4x6 tee, with the 6" main line heading across #5 fairway towards #13 and #14.  This tee is built using a 6x6x6 butt fusion tee and 2 6x4 butt fusion reducers.  A small piece of 6" pipe and a flange adapter are also fused to the 6" tee to allow a flanged connection to a 6" gate valve.

Each weld is dated, time stamped, and signed by the person who completed the weld.
