Consideration
should be given to the project performance
specified when
selecting manhole connections. When connecting to concrete manholes or
inlets grouting the pipe to the manhole or inlet using non-shrink grout
provides a soil tight installation. A gasket placed in a pipe
corrugation at the approximate center of the manhole or inlet wall will
act as a water-stop. This water-stop should provide a silt tight
installation. Watertight installations may require flexible rubber
connections such as rubber boots, "A-Loks", etc. ADS N-12/SDR- 35
adapters or the smooth exterior ADS manhole adapter pipe should be used
with flexible rubber connections.
Insert the
ADS N-12/SDR-35 or ADS manhole adapter into the flexible connector
using a lubricant as recommended by the manufacturer of the flexible
connector. The flexible connector should be sized to the OD of SDR-35
PVC pipe. When connecting to manholes, ensure backfill is placed under
the pipe adjacent to the manhole to prevent differential settlement.
