Which two methods are mentioned for installing long, continuous links of flexible polyethylene conduit underground?

• A. Plowing and trenching
• B. Plowing or pulling into the ground with a cable clown
• C. Direct burial without conduit
• D. Boring and backfilling

Answer: (B)

Installing long, continuous runs of flexible polyethylene conduit underground is typically done in two ways: plowing the conduit into the ground, or pulling it in with a pulling device such as a cable clown. Plowing uses a specialized plow to create a shallow trench and lay the conduit as it moves, making a continuous installation with minimal surface disturbance. When plowing isn’t feasible or the route requires negotiating obstacles, the conduit can be pulled into the ground through the prepared path using a pulling line and a device like the cable clown to feed the conduit in smoothly. Direct burial without conduit would skip the protective pathway entirely, so it doesn’t describe installing conduit. Boring and backfilling can route cables but isn’t the standard way to install long continuous runs of flexible conduit in one pass, and trenching alone doesn’t capture the same continuous-install approach described here.
