PRECAST MANHOLE NOTES:

1. MANHOLE STRUCTURE, MANHOLE COVER AND FRAME ARE TO BE H-20 TRAFFIC RATED. ALL MANHOLE

STRUCTURES AND MANHOLE COVERS AND FRAMES LOCATED IN AIRFIELD PAVEMENT ARE TO BE AIRCRAFT

RATED. SEE UTILITY STRUCTURES TABLE ON CU600.

2. THICKNESS AND REINFORCING FOR PRECAST CONCRETE MANHOLE WALLS AND REINFORCING FOR PRECAST CONCRETE FLAT TOPS ARE NOT SHOWN BUT SHALL CONFORM TO THE LOADING REQUIREMENTS INDICATED IN

NOTE 1.

3. MANHOLE BASE SLABS MAY BE PRECAST OR CAST-IN-PLACE CONCRETE. THICKNESS AND REINFORCING OF CAST-IN-PLACE BASE SHALL BE AS INDICATED. THICKNESS AND REINFORCING OF PRECAST BASES SHALL BE AS

REQUIRED BY MANUFACTURER. CONTRACTOR SHALL SUBMIT STRUCTURAL DRAWINGS AND DESIGN

CALCULATIONS, SIGNED AND SEALED BY A PROFESSIONAL ENGINEER REGISTERED IN THE STATE OF OKLAHOMA, FOR APPROVAL ON ALL PRECAST STRUCTURES. BUOYANCY CALCULATIONS SHALL ASSUME WATER LEVEL IS AT

GRADE.

4. ALL PIPE ENTRIES INTO THE BASE OF MANHOLES SHALL BE CONNECTED BY OPEN CHANNELS FORMED USING CAST-IN-PLACE CONCRETE BENCHES. CHANNELS SHALL BE ADJUSTED FOR PIPE SIZE, SHAPE, SLOPE, AND DIRECTION OF FLOW. THE INVERT CHANNELS SHALL BE SMOOTH AND SEMICIRULAR IN SHAPE CONFORMING TO THE INSIDE OF THE ADJACENT PIPE SECTION. CHANGES IN DIRECTION OF FLOW SHALL BE MADE WITH A SMOOTH CURVE OF AS LARGE A RADIUS AS THE SIZE OF THE MANHOLE WILL PERMIT. CHANGES IN SIZE AND GRADE OF

THE CHANNELS SHALL BE MADE GRADUALLY AND EVENLY.

5. DIAMETER OF MANHOLE SHALL DEPEND ON NUMBER AND SIZE OF PIPES CONNECTING TO THE STRUCTURE. FOR LOCATION AND ORIENTATION, SEE UTILITY PLANS SHEETS. FOR DIAMETER OF MANHOLE, SEE STRUCTURES

TABLES ON CU600, CU601 AND NOTE 15.

6. MINIMUM CONCRETE STRENGTH = 4000 PSI AT 28 DAYS UNLESS NOTED OTHERWISE. MINIMUM REINFORCING STEEL YIELD STRENGTH = 4x106 PSI.

7. USE FULL CONTACT LAP SPLICES OF REINFORCING STEEL, SEE TABLE BELOW.

8. SEE PROJECT SPECIFICATIONS SECTION 31 00 00 FOR EXCAVATION, BACKFILL AND COMPACTION REQUIREMENTS.

9. ALLOWABLE SOIL BEARING PRESSURE UNDER MANHOLES AND INLETS EQUAL TO 2500 LBS\FT².

10. LOCATE AND INSTALL 3" DIAMETER WEEP HOLES TO DRAIN SUBBASE MATERIAL PRIOR TO PAVEMENT INSTALLATION. WEEP HOLE WITH 12" X 12" PLASTIC GEOTEXTILE CLOTH WITH 1/4" MESH OR GALVANIZED STEEL WIRE DIAMETER 0.03" NUMBER 4 MESH HARDWARE CLOTH ANCHORED FIRMLY TO OUTSIDE OF STRUCTURE.

11. IF A MANHOLE IS LOCATED IN PAVEMENT AREAS. RIM ELEVATION SHALL BE FLUSH WITH FINAL GRADE. IF A MANHOLE IS LOCATED OUTSIDE OF PAVEMENT AREAS, RIM ELEVATION SHALL BE 6" ABOVE ADJACENT FINISH

GRADE AND SITE SOILS MOUNDED UP TO THE RIM OVER A DISTANCE OF 5 FT.

12. COVERS AND CASTINGS OF MANHOLES AND STRUCTURES SHALL BE STAMPED PER THE APPROPRIATE UTILITY TYPE OR PER THE LOCAL STANDARDS AND SHALL BE STAMPED PER THE ORIGIN OF MANUFACTURE. SEE DETAIL

D4 AND D5 ON CU504 FOR STANDARD FRAME AND COVER REQUIREMENT.

13. ALL JOINTS SHALL BE SEALED WITH JOINT COMPOUND OR GROUTED WITH MORTAR.

14. ANY LIFT LOOPS FOR UTILITY STRUCTURES SHALL BE GROUTED FLUSH AFTER INSTALLATION.

15. MANHOLE DIAMETERS:

USE 48" MANHOLE FOR 8"-14" OUTLET PIPE.

USE 60" MANHOLE FOR 15"-30" OUTLET PIPE.

USE 72" MANHOLE FOR 36"-42" OUTLET PIPE.

USE 84" MANHOLE FOR 48"-54" OUTLET PIPE.

USE 96" MANHOLE FOR 60"-66" OUTLET PIPE.
