Slide Rail System Keeps Lift Station Project On Time, Budget

August 2009 Vol. 64 No. 8
A slide rail system is installed simultaneously as the trench or pit is excavated by sliding the panels into integrated rails.

“The system is so ingenuous because if installed properly, all the components slide down as the hole is dug, just as the name suggests,” said Shultz. “The panels slide in the post’s rails, then the posts slide past the panels as they are pushed. There is very little binding, and almost no need to aggressively pound on the components.”

Evans rented a four sided configured slide rail system, utilizing a set of 16 by 16-foot long panels, and 24-foot corner posts to install the lift station at a 20-foot grade. To reach 20 feet, Evans’ crews installed an eight-foot panel stacked with a four-foot panel on top at the outside slotted rails of the slide rail posts. Next, they installed another set of eight-foot tall panels into the inside open face rails on the posts to reach 20 feet.

“Everything went exactly as planned, perfect really,” said Shultz. “With slide rail, we could excavate to the exact dimensions of the system without any over-cutting. This was a huge cost and time saver. We probably saved as much as the cost of a new trench box.”

Evans used Caterpillar 330 and 325 excavators to install the system and precast lift station.
