The document is a training log that summarizes two pipe replacement pulls performed by TRIC Tools. It describes the preparation, setup, and steps taken for each pull. Safety precautions and best practices are highlighted, such as having wood on hand for cribbing, finding a clear area to fuse pipes, and keeping pulling equipment clean and protected. The log documents both pulls being successful with the new pipe replacing the old vitrified clay pipe.
TRIC Training Log: Two spur replacement pulls under patio
1. TRIC Training Log: 08-04-04 Client: ARS Rescue Rooter, Dallas, TX Job: Residence, to rear property line, replacing 4” VCP Pull: two spurs, downstream / 10’ & 25’ / 4” / SDR17
2. We at TRIC Tools have specific requirements for the use and maintenance of our equipment with regard to safety and efficiency on the job. Our written and verbal recommendations coincide with safety regulations set by local, state, and national government agencies. Our clients may have standards over and above industry regulations. However, the safety equipment, apparel, and operating procedures demonstrated by our clients in this presentation may or may not comply with above mentioned government regulations.
3. Preparation: Have plenty of wood on hand for every pull. 2” x 4”, 4” x 4”, and 4” x 6” sizes are best, in 2’ to 3’ lengths for resistance cribbing, and 1’ lengths for pulley support.
4. Two pulls: Two lateral spurs join at pit where worker is digging. Rear property line is to right; main runs down service alley. This pull is less than 10 lineal feet, but still saves a lot of manual digging in hard Texas “white rock” soil.
5. First pull: Roughly 25’ under concrete patio from west lateral spur exit (dirt mound) to intersection with east spur (worker with shovel).
7. Spur junction: West spur (upper left) meets east spur (top) just inside edge of concrete patio slab. First pull set up against west spur wall of pit.
9. Fusion jig: Remove trimmings after each facing.
10. Staging area: Find an area as flat and unobstructed as possible to fuse pipe.
11. Cooling time: After fusing, allow joints to cool for 10 minutes (SDR17 4” & 6”) before removing from jig. See pipe manufacturer’s specs for more detail. Also, protect trimmer blades (above) by setting trimmer wheel down on edge rather than flat as shown.
13. First pull: Watching for the cable clevis sheath (terminator) to appear at pulley plate.
14. Arrival: Clevis sheath (in shadow under resistance plate bolt) just visible between pulley plate and pulley wheel. Keep this area free from debris to allow clear view of cable at all times, so as not to pull cable sheath under pulley wheel. Note east spur above pulley.
23. Resistance plate: Some users find it handy to cut out a copy of the resistance plate using 1” plywood. A wood template can be used to size up pulling pits as they are being dug (rather than lifting the metal plate in and out of the pit).
24. Extender cage: With a straight and clean pulling wall, often there is no need for cribbing between cage and earth. In this instance, ground is dry and solid.
25. Ram assembly: A pit roughly 4’ in length allows ample space for using the extender cage. When the pits must be shorter, extra wood cribbing is used instead of the cage.
27. Ram care: Find a clean place to set ram during job (such as a small piece of plywood). Keep jaws clean and protect chrome rods from nicks and deep scratches by keeping ram in contracted position when not in use. (Damaged rods can cause leaks in hydraulic seals.)
28. Pull complete: Cage alone (without extra cribbing) provides enough extension to free bursting head and expose pipe to trim minimum length behind PE cap.
29. Release: Cable disconnected from head assembly.
30. Spur junction: West spur (right) and VCP east spur (bottom, barely visible) ready to join new lower lateral.
