The carrier is responsible f or delivering t he pipe. Make cert ain all mat erial list ed on t he bill-of-lading has arrived. The receiver must make cert ain t here has been no loss or damage. Should t here be any errors or damage, make proper not e on t he delivery receipt . Make claim in accordance with the carrier s inst ruct ion. Do not dispose of any damaged mat erial. Carrier w ill advise you of t he procedure t o f ollow f or f reight damage. Unloading Pipe should be low ered, not dropped, f rom t rucks t o t he ground or int o a t rench.

4 DO NOT ATTEMPT TO HANDLE PIPE BUNDLES BY PULLING ON STRAPPING OR PACKAGING MATERIAL. The f orklif t t ruck, boom and sling, or ot her mat erial handling equipment should be equipped t o avoid excessive sw inging. DO NOT USE CHAINS AS A SLING. Avoid all impact blow s, gouging, or abrasions caused by met al surf aces, rocks, mat erial handling equipment, or any ot her source. Cold Weather Handling: Ext ra care should be used in handling during cold w eat her. Phot o #1 - 3 - WARNING: Carelessly unloading pipe can be hazardous. Use appropriate equipment and stay clear when removing tie-dow ns, banding, and dunnage material. TABLE 1 Trench Preparation- Proper inst allat ion procedures and t rench preparat ion are essent ial t o successf ul PVC pipe perf ormance. Trench preparat ion procedures f or PVC pipe do not vary subst ant ially f rom procedures used w it h ot her piping product s.

5 There should be no more t rench prepared t han t he f oot age of pipe w hich can be laid in a day. A t ypical t rench cross sect ion and t erminology are given in f igure 1.

The coupling should be point ed in t he direct ion of w ork progress. Trench width: Working space is t he primary considerat ion in det ermining t he t rench w idt h t o be used.

6 Trench w idt h at t he ground surf ace may vary w it h and depend upon dept h, t ype of soils, and posit ion of surf ace st ruct ures. The minimum clear w idt h of t he t rench, sheet ed or unsheet ed, measured at t he springline of t he pipe is generally specif ied at least one f oot (300 mm) great er t han t he out side diamet er of t he pipe t o enable backf ill mat erial t o be inst alled in t he haunching area. Ref er t o Figure 1 f or t he locat ion of t he haunch area. Where embedment compact ion is required, t he t rench shall be w ide enough t o accommodat e t he compact ion equipment . If minimum t rench w idt h is exceeded, and embedment compact ion is required, pipe zone haunching should be compact ed at least one pipe diamet er f rom t he pipe on bot h sides of t he pipe. Dewatering: Where condit ions are such t hat running or st anding w at er occurs in t he trench bottom or the soil in the trench bottom displays a quick tendency, the water should be removed by pumps and suit able means such as w ell point s or pervious underdrain bedding unt il t he pipe has been inst alled and t he backf ill has been placed t o a suf f icient height t o prevent pipe f lot at ion.

7 Foundation: An adequat e or st able f oundat ion should be present (or provided) t o unif ormly support t he f ull lengt h of t he pipe. Bell holes should be provided at each joint t o permit proper assembly and support of t he pipe. Unst able t rench bot t oms shall be st abilized by met hods and w it h mat erials required, by t he specif ying engineer, t o provide adequat e and permanent support f or t he condit ions encount ered. Phot o 2 Phot o 3 - 5 - Bedding: When rock, hard pan, boulders, or ot her mat erial (w hich might damage t he pipe) are encount ered in t he t rench, t he t rench bot t om should be over excavat ed 1/4t h of t he pipe diamet er, or a minimum of f our inches t o permit bedding. The bedding should consist of an evenly graded, f ree f low ing, granular mat erial w hich is f ree of large st ones or f rozen mat erial and w it h part icle size of up t o approximat ely 10% of t he pipe size and no larger t han 1 in size.

8 Bell holes should be ut ilized t o reduce axial def lect ion and support t he barrel of t he pipe. -Lubricant- Clean any dirt or f oreign mat t er f rom t he gasket and spigot . An even, unif orm applicat ion of gasket lubricant must be applied t o t he bevel and spigot t o t he f irst insert ref erence mark as w ell as t he cont act surf ace of t he gasket . Gasket lubricant may be applied w it h a sw ab, brush, or roller. Gasket lube is f urnished w it h each t ruckload of pipe. Addit ional lubricant may be purchased f rom your dist ribut or. Phot o 4 Phot o 5 (in open st orage) Phot o 6 (remove debris) Phot o 7 (clean annular space) Phot o 8 (lubricat e gasket ) Phot o 9 (lubricat e spigot ) - 6 - -Assembly- Assembly is made by sliding t he lubricat ed spigot end int o t he gasket ed bell end.

9 The gasket seals t he joint against leaks, int o or out of t he pipeline. Insert t he spigot end int o t he socket so t hat it is near cont act w it h t he gasket . Keep t he pipe lengt hs in proper alignment . Brace t he bell w hile t he spigot end is pushed t hrough t he gasket so t hat previously complet ed joint s in t he line will not be stacked, over belled, or insert ed past t he second ref erence mark. (ref er t o Encasement s.) Push t he spigot end in unt il t he lip of t he bell is bet w een t he ref erence marks on t he spigot end. If t he spigot is insert ed beyond t he f irst insert ref erence mark, laying lengt h w ill be lost . Loss of laying lengt h can be signif icant on long f oot age project s. Also, joint f lexibilit y is reduced w hen t he spigot is insert ed beyond t he second insert ref erence mark.

10 Some joint s may require barring t o seat t he joint . If so, use a w ood block t o prot ect t he end of t he pipe. A come-a-long may be pref erred t o t he bar and block, but a sw inging st ab is not recommended. Where t he physical w eight or t rench condit ions make t he recommended met hods unsaf e, joint s may be assembled using mechanical equipment provided t hat t he pipe is properly lubed and aligned. The end must be prot ect ed f rom damage, and t he joint must not be over belled or inserted beyond the second insert ref erence mark. If t he second insert ion mark is not visible af t er assembly, t he pipe w as over-insert ed. The joint needs t o be disassembled and done correct ly. Likew ise, if t he f irst mark f alls w ell short of t he lip of t he bell, t he pipe needs t o be pushed a lit t le f urt her unt il t he lip is bet w een t he t w o ref erence marks.
