Where no ifting devices are provided, the CONTRACTOR shall follow the manufacturer's recommendations for lifting procedures to provide proper support during lifting. B. The manhole base shall be poured in place against a minimum of 6-inches of 3/4" crushed rock base situated on undisturbed soil. The manhole stubs and sewer main shall be set before the concrete is placed and shall be rechecked for alignment and grade before the concrete has set. The various sized inlets and outlets to Vie manhole shall be located as indicated on the Approved Plans. The manhole base shall extend 9- inches below the bottom of the lowest pipe. Invert elevations of connecting sewers may vary depending upon sizes. When intercepting flows from smaller pipelines in manholes, set invert of the smaller mains at % of the depth of the larger main. The invert of the manhole base shall be hard worked so as to provide channels conforming in size and shape to the lower portions of the inlets and outlets. The channel shall vary uniformly in size and shape from inlet to outlet and be constructed higher than pipe as indicated on the Approved Plans. The manhole invert channels shall be smooth and accurately shaped. Channels may be formed directly in the concrete base. All transitions shall be smooth and of the proper radius to give an uninterrupted transition of flow. The concrete base shall be shaped with a wood float and shall receive a hard-steel trowel finish prior to the concrete setting. SECTION 03460 JUNE 2008 4 of 7 Precast Concrete Sewer Manholes In the event additional mortar is required after initial set has taken place, the surface to receive the mortar shad be primed and the mortar mixed with "Willhold Concrete Adhesive* in the amounts and proportions recommended. The bases shall set a minimum of 24 hours before the manhole construction is continued. C. Straight through channels in manholes with no tributaries may have SDR 35 PVC pipe instated though the manhole. The top section of pipe shall be removed flush with top of shelf. All cuts shall be neat and dressed minimizing burrs and rough edges. D. Each manhole section shall be seated with butyl rubber sealant rope (See Detail on Std Dwg S-1A) to make a watertight joint, shall be neatly banded on the inside and outside and shall be set plumb. AH manholes shall be vacuum tested in accordance with the procedures specified herein in paragraph 3.3 and shown on Carlsbad Standard Drawing S-1A. Sections of various height grade rings shall be used in order to bring the top of the manhole ring and cover to the elevation on the Approved Plans, but limited to a maximum of 18 inches of grade ring. The precast concrete manhole rings shall be jointed with a minimum thickness of H inch of Portland cement mortar along with butyl rubber sealant rope. Mortar shall be composed of one part Portland cement to two parts dean well-graded sand of such size that all pass a No. 8 sieve. Preformed, cold applied ready-to-use plastic joint sealing compound may be substituted for mortar between units and shall be used when ground water is encountered. The finished elevations at which the manhole frames and covers are to be set shall conform to the requirements set forth in the Approved Plans. Where the frame and cover are in existing pavement or in the traveled way of the existing road shoulder, it is to be placed flush with the existing surface. When the structure is outside the limits of the traveled shoulder but not in the roadside ditch, it should be placed 1/10-foot above the existing ground surface. Where the manhole cover falls in the existing roadside ditch or easement right-of-way "offsite", it is to be placed approximately 6-inches above the existing ground surface. Manhole frames shall be set at the required grade and shall be securely attached to the top precast manhole shaft unit with a cement-mortar bed and fillet. After the frames are securely set in place, covers shall be installed and all necessary cleaning and scraping of foreign materials from the frames and covers shall be accomplished to ensure a satisfactory fit. E. Damp-proof material shall be applied, when ground water is present or anticipated and at the discretion of the City Engineer, to the exterior surfaces of mart-holes in accordance with the manufactures recommendations. The material shall be applied to all exterior surfaces below a point one foot above the water table or indications of seepage or moisture as directed by the Engineer. Use water-proofing material for exterior surface when below ground water, per Std Dwg S-1A or as required by Engineer. F. Selected clean backfill material shall be used around all man-holes. It shall be compacted by pneumatic tampers as shown on Standard Drawing No. S-5, unless shown otherwise on the approved plans. G. A concrete ring shall be cast around manhole frames to within 3" of finished grade and capped with asphalt, as shown on the Approved Plans. The ring shall be placed after the final grading or paving together with the final cleanup. SECTION 03460 JUNE 2008 5of7 Precast Concrete Sewer Manhotes 3.2 WATER-TIGHTNESS OF MANHOLES A. It is the intent that all man-holes and appurtenances be water tight and free from infiltration. All man-hole joints shall use butyl rubber sealant material to provide a water tight seal and shall comply with the vacuum test requirements specified herein in paragraph 3.3 of this Section. Where manholes are to be given a protective lining or coating, they shall be free of any seeping or surface moisture. Sections of manholes below ground water levels or anticipated ground water levels shall have sealant material installed on the external surface per Std Dwg S-1A. 3.3 VACUUM TESTING OF MANHOLES A. All sewer manholes shall be vacuum tested in accordance with the requirements specified herein. B. Vacuum testing equipment shall be as manufactured by P.A. Glazier, inc. or approved equal. C. Manholes shall be tested after assembly and prior to mortaring the joints or backfilling. In case of manholes incorporating a PVC liner, the testing is to take place prior to mortaring the joints, welding the liner seams between sections, and backfilling. D. All lift holes shall be plugged with an approved grout prior to testing. All pipes entering the manhole shall be plugged and bracing installed to prevent the plug from being drawn into the manhole. The test head shall be placed inside the top of the cone section and the seal inflated in accordance with the manufacture's recommendations. A vacuum of 10 inches of mercury shall be drawn. The time shall be measured for the vacuum to drop 9-inches. The manhole shall pass the test if the time taken for the drop is greater than 60 seconds. If the manhole fails the test, necessary repairs shall be made and the test repeated until acceptable results are obtained. The leak(s) shall be located and repaired, according to the type of leak, with material-in-kind. 3.4 PULL-TESTING OF PVC-LINED MANHOLES At the Engineers request, PVC-tined manholes shall have field-welded joints pull tested. Field welds shall withstand a pull test of at least 100 pounds per linear inch applied perpendicularly to the concrete surface for a period of one-minute without evidence of cracks or separation. This test shall be conducted at a temperature of 70°F to 80°F, inclusive. 3.5 HOLIDAY TESTING OF PVC-LINED MANHOLES PVC-lined surfaces shall be holiday tested with an electrical holiday detector as manufactured by Tinker and Rasor (model No. AP-W with power pack) with the instrument set at 20,000 volts and used as directed by the Engineer. All imperfections identified on the PVC lining shall be repaired and the test shall be repeated until no holidays are evident. SECTION 03460 JUNE 2008 6 of 7 Precast Concrete Sewer Manholes 3.6 MANHOLE ABANDONMENT Sewer manholes shall have the cover and frame, concrete ring, grade rings and cone section removed. Inlet and outlet piping shaft be plugged with concrete, manhole void shall be filled with sand, and a 12" thick, reinforced concrete slab shall be poured over the top of remaining manhole. The Contractor shall backfill the hole to ground surface with compacted select fill.
