Abstract:

This report deals with the selection of a test site, the design of a test installation, equipment selection, the installation and start-up of a pneumatic pipeline system for the transportation of tunnel muck. A review of prior pneumatic applications (Appendix A) provided knowledge on the state-of-the-art and a basic background for the design of the test equipment and development of a tentative test program. A suitable site was found four miles from the campus, and the site was prepared, equipment ordered, installed, and checked-out. The installation comprises a muck preparation unit, blower-feeder assembly, two telescoping pipes in series, 500 ft. of 10-inch diameter pipe with a vertical lift of 160 ft. on a 27 degree slope. The test unit is a full scale 100 ton per hour pneumatic transport system in a configuration suitable for application in a tunnel and capable of being extended under load to simulate service requirements. The test system developed has the capability to transport 100 tons/per hour of rock through a 10 inch pipeline approximately 550 feet long with vertical lift of 160 feet.
