Installation Instructions

SCOPE:'

This'is'an'outline'of'procedures'for'the'installation'of'Prinsco'corrugated'HDPE'pipe'for'Storm'Sewer'and'Culvert'

applications'in'accordance'with'ASTM'and'AASHTO'specifications.'

PRINCIPAL'INSTALLATION'REFERENCES:

ASTM'D'2321:'Standard'Practice'for'Underground'Installation'of'Flexible'Thermoplastic'Sewer'Pipe

AASHTO'SECTION'30,'DIVISION'II:'Standard'Specifications'for'Highway'Bridges

GENERAL:'

Corrugated'HDPE'pipe,'as'with'all'buried'pipe,'functions'as'a'buried'structure'where'the'performance'of'the'structure'

is'dependent'on'the'quality'of'installation.''This'installation'related'information'serves'as'a'general'guide'for'many'

common'field'conditions'and'stormwater'management'applications.'''Some'projects,'however,'may'have'specific'

conditions'or'performance'criteria'beyond'the'scope'of'this'installation'guideline'and'shall'be'addressed'by'the'design'

Engineer.

TRENCH'INSTALLATION:'

For'maximum'performance,'the'width'of'the'trench'should'be'restricted'to'what'is'essential'to'safely'position'and'

compact'the'backfill'material'on'both'sides'of'the'pipe.''The'trench'width'should'be'no'wider'than'what'is'represented'

in'Table'2,'except'as'necessary'to'construct'the'trench'or'install'the'pipe.'AASHTO'Section'30'recommends'a'

minimum'trench'width'of'1.5'times'the'pipe'O.D.'plus'12".''ASTM'D2321'recommends'the'greater'of'either'the'pipe'

O.D.'plus'16"'or'1.25'times'the'pipe'O.D.'plus'12".

BACKFILL'MATERIALS:'

Installed'pipe'performance'is'dependent'upon'the'envelope'material’s'installed'density'and'its'resistance'to'migration'

or'disintegration'under'service'conditions.'Table'3'provides'a'listing'and'classification'of'common'backfill'materials'

along'with'detailed'descriptions'of'each'material.'Table'4'provides'guidance'for'the'proper'use'and'placement'of'

acceptable'backfill'materials'within'each'specific'zone'of'the'pipe-soil'envelope.''The'information'provided'in'tables'3'

and'4'are'based'on'ASTM'D2321'and'the'backfill'materials'listed'are'typically'used'for'all'pipe'materials'(i.e.'reinforced'

concrete'pipe,'corrugated'metal'pipe,'etc.')'operating'under'similar'performance'criteria.'

Each'type'of'backfill'has'associated'advantages'and'disadvantages'related'to'cost,'permeability,'strength,'and'ease'

of'use'these'traits'along'with'the'project'specific'criteria'should'be'used'for'the''selection'of'an'appropriate'backfill'

material.'

INSTALLATION'AND'JOINT'CONNECTIONS:'

GOLDFLO'and'ECOFLO'Dual-Wall'Pipe'is'available'with'standard'or'gasketed'fittings.'Pipe'lengths'may'need'to'

be'altered'in'the'field'to'comply'with'site'requirements.'GOLDFLO'can'be'easily'cut'to'length'with'a'hand'saw,'

reciprocating'saw,'or'an'equivalent'tool.'Always'make'the'cut'in'the'valley'of'the'corrugation.'

Bends'of'22-1/2º,'45º'and'90º'are'made'using'standard'or'gasketed'Prinsco'elbows.''Prinsco'recommends'that'all'

curvatures'be'limited'to'the'joint'for'GOLDFLO'and'ECOFLO'pipe'(dual'wall'pipe),'however'GOLDLINE'pipe'may'be'

installed'in'a'curved'trench'with'a'bend'radius'not'to'exceed'3'times'the'diameter.''For'example,'this'would'result'to'a'

bend'radius'of'30"'for'10"'GOLDLINE'pipe.'
