The following example illustrates the process given aninstallation using the machine at an 18% pitch on levelground:• You insert the first 3 m (10 ft) of drill bit/pipe into theground with no steering. The end of the drill bit will be53 cm (21 inches) deep (Figure 29).1 23 4g02176965Figure 291. 18% pitch 3. 96 cm (38 inches) 5. 119 cm (47 inches)2. 53 cm (21 inches) 4. 114 cm (45 inches) 6. 10.6 m (35 ft)• You begin steering up for the next 3 m (10 ft), pushing thepipes in at the maximum pitch change of 8%. This resultsin a change of pitch from 18% at the beginning of the 3 m(10 ft) to 10% at the end of the 3 m (10 ft) for an averagepitch of 14%. Given that, the drill head lowers another 43cm (17 inches) and is now 96 cm (38 inches) deep.• Continuing steering up for the next 3 m (10 ft) at an 8%pitch change, your pitch will change from 10% to 2% foran average pitch of 6%. Given that, the drill head lowersanother 18 cm (7 inches) and is now 114 cm (45 inches)deep.• Leveling the drill head from 2% to 0% takes less than 1.5m (5 ft) more for a final depth of 119 cm (47 inches).Reaching this final point took three and a half, 3 m (10ft) pipes. So for this example your entry point should be10.6 m (35 ft) back from the beginning-at-depth point ofyour installation.Important: You can use the information contained inthis section to determine both the space needed to steerup to the exit point if needed and also to steer aroundobstacles.Mapping the BoreWith the information you gathered previously, map out theroute of the bore, identifying the following so that you canmark the site later:• Entry point• Location of the machine and supporting equipment• Beginning of bore at depth• Any obstacles that you need to steer around and thelocations where you need to start steering to get aroundor under them• Any utility lines you will need to cross• Slope and soil changes along the path that will affect thebore• End of the bore at depth• Exit location if different than the end of the bore38
