1.0. DETAILS AND DIMENSIONS OF LINER SHEETS. LINER SHEETS SHALL BE A
MINIMUM OF 0.065 INCH (1.65 MM) IN THICKNESS. LOCKING EXTENSIONS OF THE
SAME MATERIAL AS THAT OF THE LINER SHALL BE INTEGRALLY EXTRUDED WITH THE
SHEET.
I.E. INSTALLATION OF LINING. INSTALLATION OF THE LINING, INCLUDING PREHEATING
OF SHEETS IN COLD WEATHER AND THE WELDING OF ALL JOINTS, SHALL BE DONE IN
ACCORDANCE WITH THE RECOMMENDATIONS OF THE LINER MANUFACTURER.
COVERAGE OF THE LINING SHALL NOT BE LESS THAN THE MINIMUM SHOWN ON
THE PLANS.
THE LINING SHALL BE INSTALLED WITH THE LOCKING EXTENSIONS RUNNING PARALLEL
WITH THE LONGITUDINAL AXIS OF THE PIPE.
THE LINING SHALL BE HELD SNUGLY IN PLACE AGAINST INNER FORMS.
LOCKING EXTENSION SHALL TERMINATE NOT MORE THAN 1-1/2 INCHES (38 MM)
FROM THE END OF THE INSIDE SURFACE OF THE PIPE SECTION. JOINT FLAPS WHEN
USED SHALL EXTEND APPROXIMATELY 4 INCHES (100 MM) BEYOND THE END OF THE
INSIDE SURFACE.
CONCRETE POURED AGAINST LINING SHALL BE VIBRATED, SPADED OR COMPACTED IN
A CAREFUL MANNER SO AS TO PROTECT THE LINING AND PRODUCE A DENSE,
HOMOGENOUS CONCRETE. SECURELY ANCHORING THE LOCKING EXTENSIONS INTO THE
CONCRETE.
IN REMOVING FORMS, CARE SHOULD BE TAKEN TO PROTECT THE LINING FROM
DAMAGE. SHARP INSTRUMENTS SHALL NOT BE USED TO PRY FORMS FROM LINED
SURFACES. WHEN FORMS ARE REMOVED, ANY NAILS THAT REMAIN IN THE LINING SHALL
BE PULLED, WITHOUT TEARING THE LINING, AND THE RESULTING HOLES CLEARLY MARKED.
ALL NAIL AND TIE HOLES AND ALL CUT, TORN AND SERIOUSLY ABRADED AREAS IN
THE LINING SHALL BE PATCHED. PATCHES MADE ENTIRELY WITH WELDING STRIP SHALL
BE FUSED TO THE LINER OVER THE ENTIRE PATCH AREA. LARGER PATCHES MAY
CONSIST OF SMOOTH LINER SHEET APPLIED OVER THE DAMAGED AREA WITH ADHESIVE.
ALL EDGES MUST BE COVERED WITH WELDING STRIP FUSED TO THE PATCH AND THE
SOUND LINING ADJOINING THE DAMAGED AREA.
HOT JOINT COMPOUNDS, SUCH AS COAL TAR, SHALL NOT BE POURED OR APPLIED
TO THE LINING.
THE CONTRACTOR SHALL TAKE ALL NECESSARY MEASURES TO PREVENT DAMAGE TO
INSTALLED LINING FROM EQUIPMENT AND MATERIALS USED IN OR TAKEN THROUGH THE
WORK.
1.F APPLICATION TO CONCRETE PIPE - SPECIAL REQUIREMENTS. THE LINING
SHALL BE SET FLUSH WITH THE INNER EDGE OF THE BELL OR SPIGOT END OF A PIPE
SECTION AND SHALL EXTEND TO THE OPPOSITE END OR TO APPROXIMATELY 4 INCHES
(100 MM) BEYOND THE OPPOSITE END DEPENDING UPON THE TYPE OF LINING JOINT
TO BE MADE WITH THE ADJOINING CONCRETE PIPE.
WHEREVER CONCRETE PIPE OR CAST -IN-PLACE STRUCTURES PROTECTED WITH LINING,
JOIN STRUCTURES NOT SO LINED (SUCH AS BRICK STRUCTURES, CONCRETE PIPE OR
CAST -IN-PLACE STRUCTURES WITH CLAY LINING OR CLAY PIPE), THE LINING SHALL BE
EXTENDED OVER AND AROUND THE END OF THE PIPE AND BACK INTO THE STRUCTURE
FOR NOT LESS THAN 4 INCHES (100 MM). THIS PROTECTING CAP MAY BE MOLDED
OR FABRICATED FROM THE LINING MATERIAL BUT NEED NOT BE LOCKED INTO THE PIPE.
WHERE A PIPE LATERAL (NOT OF PLASTIC LINED CONCRETE) IS INSTALLED THROUGH
LINED CONCRETE PIPE, THE SEAL BETWEEN THE LINED PORTION AND THE LATERAL SHALL
BE PER THE MANUFACTURER'S RECOMMENDATIONS.
LINED CONCRETE PIPE MAY BE CURED BY STANDARD CURING METHODS.
CARE SHALL BE EXERCISED IN HANDLING, TRANSPORTING AND PLACING LINED PIPE
TO PREVENT DAMAGE TO THE LINING. NO INTERIOR HOOKS OR SLINGS SHALL BE USED
IN LIFTING PIPE. ALL HANDLING OPERATION SHALL BE DONE WITH AN EXTERIOR SLING OR
WITH A SUITABLE FORK UFT.
ON PIPE HAVING A 360' LINER COVERAGE, THE LONGITUDINAL EDGES OF THE
SHEET SHALL BE BUTT WELDED. WHEN PIPE TUBES ARE FURNISHED, THESE ARE
SHOP -WELDED JOINTS.
NO PIPE WITH DAMAGED LINING WILL BE ACCEPTED UNTIL THE DAMAGE HAS BEEN
REPAIRED TO THE SATISFACTION OF THE ENGINEER.
1.G. FIELD JOINTS IN LINING FOR CONCRETE PIPE. THE JOINT BETWEEN
SECTIONS OF LINED PIPE SHALL BE PREPARED IN THE FOLLOWING MANNER:
IF REQUIRED, THE INSIDE JOINT SHALL BE FILLED AND CAREFULLY POINTED WITH
CEMENT MORTAR IN SUCH A MANNER THAT THE MORTAR SHALL NOT, AT ANY POINT,
EXTEND INTO THE PIPE BEYOND THE STRAIGHT UNE CONNECTING THE SURFACES OF THE
ADJACENT PIPE SECTIONS.
PIPE JOINTS MUST BE DRY BEFORE LINING JOINTS ARE MADE.
ALL MORTAR AND OTHER FOREIGN MATERIAL SHALL BE REMOVED FROM LINING
SURFACES ADJACENT TO THE PIPE JOINT, LEAVING THEM CLEAN AND DRY.
FIELD JOINTS IN THE LINING AT PIPE JOINTS MAY BE EITHER OF THE FOLLOWING
DESCRIBED TYPES:
TYPE P-1: THE JOINT SHALL BE MADE WITH A SEPARATE 4 -INCH (100 -MM)
JOINT STRIP AND TWO WELDING STRIPS. THE 4 -INCH (100 -MM) JOINT STRIP SHALL BE
CENTERED OVER THE JOINT, HEAT -SEALED TO THE LINING, THEN WELDED ALONG EACH
EDGE TO ADJACENT LINER SHEETS WITH A 1 -INCH (25 -MM) WELD STRIP. THE 4 -INCH
(100 -MM) JOINT STRIP SHALL LAP OVER EACH SHEET A MINIMUM OF 1/2 INCH (13
MM).
TYPE P-2: THE JOINT SHALL BE MADE WITH A JOINT FLAP WITH LOCKING
EXTENSIONS REMOVED AND EXTENDING APPROXIMATELY 4 INCHES (100 MM) BEYOND
THE PIPE END. THE JOINT FLAP SHALL OVERLAP THE LINING IN THE ADJACENT PIPE
SECTION A MINIMUM OF 1/2 INCH (13 MM) AND BE HEAT -SEALED IN PLACE PRIOR
TO WELDING. THE FIELD JOINT SHALL BE COMPLETED BY WELDING THE FLAP TO THE
LINING OF THE ADJACENT PIPE USING 1 -INCH (25 -MM) WELD STRIP.
CARE SHALL BE TAKEN TO PROTECT THE FLAP FROM DAMAGE. EXCESSIVE TENSION
AND DISTORTION IN BENDING BACK THE FLAP TO EXPOSE THE PIPE JOINT DURING LAYING
AND JOINT MORTARING SHALL BE AVOIDED. AT TEMPERATURES BELOW 50 F(10 C),
HEATING OF THE LINER MAY BE REQUIRED TO AVOID DAMAGE.
THE JOINT FLAP OR STRIP ON BEVELED PIPE SHALL BE TRIMMED TO A WIDTH
(MEASURED FROM THE END OF THE SPIGOT) OF APPROXIMATELY 4 INCHES (100 MM)
FOR THE ENTIRE CIRCUMFERENTIAL LENGTH OF THE LINING.
ALL WELDING OF JOINTS IS TO BE IN STRICT CONFORMANCE WITH THE
SPECIFICATIONS AND INSTRUCTIONS OF THE LINING MANUFACTURER.
WELDING SHALL FUSE BOTH SHEETS AND WIELD STRIP TOGETHER TO PROVIDE A
CONTINUOUS JOINT EQUAL IN CORROSION RESISTANCE AND IMPERMEABILITY TO THE LINER
PLATE.
HOT-AIR WELDING TOOLS SHALL PROVIDE EFFLUENT AIR TO THE SHEETS TO BE
JOINED AT A TEMPERATURE BETWEEN 500 AND 600 F (260 AND 316 C).
WIELDING TOOLS SHALL BE HELD APPROXIMATELY 1/2 INCH (13 MM) FROM AND MOVED
BACK AND FORTH OVER THE JUNCTION OF THE TWO MATERIALS TO BE JOINED. THE
WILDING TOOL SHALL BE MOVED SLOWLY ENOUGH AS THE WIELD PROGRESSES TO CAUSE
A SMALL BEAD OF MOLTEN MATERIAL TO BE VISIBLE ALONG BOTH EDGES AND IN FRONT
OF THE WI=LD STRIP.
THE FOLLOWING SPECIAL REQUIREMENT SHALL APPLY WHEN THE LINER COVERAGE IS
360 DEGREES:
WHEN GROUNDWATER IS ENCOUNTERED THE LINING JOINT SHALL NOT BE MADE UNTIL
PUMPING OF GROUNDWATER HAS BEEN DISCONTINUED FOR AT LEAST THREE DAYS AND
NO VISIBLE LEAKAGE IS EVIDENT AT THE JOINT.
WIEN WIELDING THE DOWNSTREAM SIDE OF A JOINT STRIP OR FLAP, DO NOT WELD
6 TO 8 INCHES (150 TO 200 MM) AT THE PIPE INVERT TO PROVIDE RELIEF OF
POTENTIAL FUTURE GROUNDWATER BUILD-UP.
I.H. APPLICATION TO CAST -IN-PLACE CONCRETE STRUCTURES - SPECIAL
REQUIREMENTS. LINER SHEETS SHALL BE CLOSELY FITTED AND PROPERLY SECURED TO
THE INNER FORMS. SHEETS SHALL BE CUT TO FIT CURVED AND WARPED SURFACES
USING A MINIMUM NUMBER OF SEPARATE PIECES.
UNLESS OTHERWISE SHOWN ON THE PLANS., THE LINING SHALL BE RETURNED AT
LEAST 3 INCHES (75 MM) AT THE SURFACES OF CONTACT BETWEEN THE CONCRETE
STRUCTURE AND ITEMS NOT OF CONCRETE (INCLUDING MANHOLE FRAMES, GATE GUIDES,
CLAY PIPE OR BRICK MANHOLES AND GRAY OR CAST IRON PIPES). THE SAME
PROCEDURE SHALL BE FOLLOWED AT JOINTS WHERE THE TYPE OF PROTECTIVE LINING IS
CHANGED OR THE NEW WORK IS BUILT TO JON EXISTING UNLINED CONCRETE. AT EACH
RETURN, THE RETURNED LINER SHALL BE SEALED TO THE ITEM IN CONTACT WITH THE
PLASTIC -LINED CONCRETE. IF THE LINER CANNOT BE SEALED WITH ADHESIVE BECAUSE
