Shift work occurs in a work schedule that utilizes 24 hours a day and occasionally, 7 days a week, to keep an organization operating. Shift work occurs whenever 24-hour coverage is necessary or when a 24 hour day optimizes work output and productivity.
You want to cut at a 45-degree angle so that the PVC ends in a sharp point. The rest is just a matter of cementing the PVC to the adapter and attaching it to your hose. Trench, Then Tunnel. The first step in tunneling under a sidewalk is to dig a trench perpendicular to the sidewalk. You want it to be deep enough to let you tunnel several inches below the bottom of the sidewalk and as long as the PVC pipe you attached to the hose.
Make another trench on the other side of the driveway where the tunnel is to emerge. This one should be about 2 feet long and several inches deeper than the level of the tunnel, so water and mud can drain into it. Lay the pipe in the trench with the open end pointed toward the driveway. Put on your eye protection, because the water may throw back mud and small stones as it digs. Turn on the water full blast. It will immediately begin to tunnel into the soil under the driveway. Push the pipe into the hole as it is created. Stop occasionally and pull the pipe out of the hole allowing it to drain. You may need to clear out some of the mud in the trench with the shovel before putting the water pipe back in the tunnel.
