1. THIS JUNCTION STRUCTURE SHALL BE USED WHEN THE OUTSIDE DIAMETER
OF THE LATERAL IS GREATER THAN 1/2 THE INSIDE DIAMETER D OF THE
MAIN LINE: OR WHEN THE INSIDE DIAMETER B OF THE LATERAL IS GREATER
THAN 600 mm (240). B SHALL NOT EXCEED .75 D OR 975 mm (390).
2. IF THE MAIN LINE IS A REINFORCED MONOLITHIC ARCH STORM DRAIN.
D SHALL REFER TO THE CLEAR SPAN OF THE ARCH. REINFORCING STEEL
SHALL BE CUT AND BENT INTO THE JUNCTION STRUCTURE IN THE SAME
MANNER AS FOR A PIPE. A CONCRETE CRADLE IS NOT REQUIRED FOR A
REINFORCED MONOLITHIC ARCH.
3. STATIONS SHOWN ON THE PROJECT DRAWINGS FOR LATERALS APPLY AT THE
INTERSECTION OF CENTER LINES OF MAIN LINE AND LATERAL. STATIONS
SHOWN ON THE PROJECT DRAWINGS FOR CATCH BASIN CONNECTOR PIPES
APPLY AT THE INTERSECTION OF THE INSIDE WALL OF THE MAIN LINE WITH
THE CONNECTOR PIPE CENTER LINE.
4. VALUES .FOR A. B. C AND D SHALL BE SHOWN ON THE PROJECT DRAWINGS.
ELEVATION R AND ELEVATION S SHALL BE SHOWN ONLY WHEN REQUIRED PER
NOTE 5.
5. a. ELEVATIONS R AND S NEED NOT BE SHOWN ON THE PROJECT DRAWINGS
IF THE INLET PIPE IS TO ENTER THE MAIN LINE RADIALLY.
b. ELEVATION R SHALL BE SHOWN ON THE PROJECT DRAWINGS ONLY IF A
STUB IS TO BE PROVIDED IN THE MAIN LINE FOR FUTURE CONNECTION
OF AN INLET PIPE. '
c. ELEVATION S SHALL BE SHOWN ON THE PROJECT DRAWINGS IF AN INLET
PIPE IS TO ENTER THE MAIN LINE OTHER THAN RADIALLY. INLET PIPE
SHALL BE LAID ON A STRAIGHT GRADE FROM ELEVATION S TO THE
CATCH BASIN OR GRADE BREAK IN LINE.
6. THE INLET PIPE SHALL ENTER THE MAIN LINE RADIALLY UNLESS OTHERWISE
INDICATED. THE INLET PIPE MAY ENTER THE MAIN LINE OTHER THAN
RADIALLY IF ANGLE A IS GREATER THAN 450. 8 IS LESS THAN OR EQUAL TO
600 mm (240) AND THE OUTSIDE DIAMETER OF THE INLET PIPE IS LESS THAN
.5 D: OTHERWISE. STANDARD PLAN 340 SHALL BE USED.
7. NO MORE THAN ONE OPENING SHALL BE MADE IN ANY ONE SECTION OF PIPE.
S. THE OPENING FOR THE BREAKOUT SHALL BE RECTANGULAR AND CUT NORMAL
TO THE PIPE SURFACE WITHOUT DAMAGING THE REINFORCING STEEL. THE
TRANSVERSE REINFORCEMENT OF THE MAIN LINE SHALL BE CUT AT THE
CENTER OF THE OPENING AND BENT INTO THE TOP AND BOTTOM SLABS OF
THE SPUR.
9. THE MAIN LINE SHALL BE REINFORCED WITH A CONCRETE CRADLE AND
ENCASEMENT (AS APPLICABLE). A CONCRETE ENCASEMENT IS REQUIRED IF A
JOINT IN THE MAIN LINE FALLS WITHIN THE LIMITS OF THE CRADLE. THE
CONCRETE ENCASEMENT SHALL EXTEND 300 mm (12') ABOVE THE TOP OF THE
MAIN LINE AND TO THE LIMITS. OF THE CRADLE.
IF CONNECTING TO AN EXISTING STORM DRAIN, PORTION OF CRADLE
OPPOSITE INLET MAY BE OMITTED.
10. REINFORCING STEEL SHALL CONFORM TO ASTM A 615M. GRADE 300. (ASTM A 615.
GRADE 40), AND BE PLACED 40 mm (1 1/2') CLEAR FROM CONCRETE SURFACES.
UNLESS OTHERWISE SHOWN F BARS SHALL BE CARRIED TO A POINT NOT LESS
THAN J DISTANCE FROM CENTER LINE WITH J=70/12 + 150 mm (61).
I1. FLOOR OF THE SPUR SHALL BE STEEL -TROWELED TO THE SPRING LINE OF
THE SPUR.
12. DIMENSIONS SHOWN ON THIS PLAN FOR METRIC AND ENGLISH UNITS ARE NOT
EXACT EQUAL VALUES. IF METRIC VALUES ARE USED. ALL VALUES USED FOR
CONSTRUCTION SHALL BE METRIC VALUES, EXCEPT REINFORCING BAR$ SIZES IN
ENGLISH UNITS MAY BE SUBSTITUTED FOR METRIC BAR SIZES. IF ENGLISH UNITS
ARE USED, ALL VALUES USED FOR CONSTRUCTION SHALL BE ENGLISH UNITS.
