Manholes

Aveng Infraset manhole products bear the SABS mark and are designed, manufactured and tested in accordance with SANS 1294.

Options for Manhole Configurations -

  • Option 2 does away with the adaptor and shaft section/s and instead of a reducer slab, a cover slab is used.
  • Option 3 does away with the frame, spacer, adaptor and access shaft used in Option 2, with the lid fitting directly into the Ekgangala slab.

OPTION 1

NB – Cast iron frames 2 & 2A require square adaptors and spacers while cast iron frames 4 & 4A require round adaptors and spacers.

Heavy duty lids tests to 120kN.

Medium duty lids tests to 60kN.

Both heavy and medium duty lids fit in the frame which is 130mm high.

A round spacer can be used. This is 75mm high. A square spacer is 100mm high.

Access shaft sections are 750mm in diameter and available in heights of 250, 500 and 1 000mm.

The reducer slab reduces chamber sections to 750mm shaft sections and is available in four sizes (1 000, 1 250, 1 500 and 1 750) and heights respectively (150, 185, 220 and 220mm) and has a 750mm diameter hole. Option 2 allows for a cover slab instead on which a frame and lid can be fitted.

Throughout all options three types of bases can be used. Precast complete with benching, a cast-in-situ foundation using a 250mm chamber section or a 500mm section conversion.

 

OPTION 2

Option 2 does away with the adaptor and shaft section/s and instead of a reducer slab, a cover slab is used.

NB – Cast iron frames 2 & 2A require square spacers.

NB – Cast iron frames 4 & 4A require round spacers.

Heavy duty lid tests to 120kN. Medium duty lid tests to 60kN.

Both heavy and medium duty lid fit in the frame which is 130mm high.

A round spacer can be used. This is 75mm high. A square spacer is 100mm high.

The cover slab is available in four sizes (1 000, 1 250, 1 500 and 1 750) and heights (150, 185, 220 and 220mm) respectively and has a 560mm hole.

Throughout all options, three types of bases can be used. Precast complete with benching, a cast-in-situ foundation using a 250mm chamber section or a 500mm sec-tion conversion as shown here.

Please note that the drilled holes should not be closer than 150mm from either the top or bottom of the section.Example dimensions are shown.

 

OPTION 3

Option 3 does away with the frame, spacer, adaptor and access shaft used in Option 2, with the lid fitting directly into the Ekgangala slab.

Heavy duty lid tests to 120kN.

Medium duty lid tests to 60kN.

The Ekgangala slab accommodates the lid directly. It is available in five sizes (750, 1 000, 1 250, 1 500 and 1 750mm) and heights (100, 150, 185, 220 and 220mm) respectively.

A 250mm chamber section is used to construct a cast-in-situ foundation.

Throughout all options, three types of bases can be used.

Precast complete with benching, a cast-in-situ foundation using a 250mm chamber section or a 500mm section conversion.
