Possibilities for fillingpoints - Sewage

Possibilities for ventilation - Sewage

Possible Constructions for connections for Benefil Hardfoam

1. Possibilities for fillingpoints

• 1.1 Manhole that will be taken away
  1.2 Manhole that will be taken away with more connections
  1.3 Manhole that should be kept in good order ( intact)
  1.4 No Manhole
  1.5 Steel Tube/Pipe
  1.6 Sewage only accessible from one side

2. Possibilities for ventilation

• 2.1 Manhole that will be taken away
  2.2 Manhole that should be kept in good order ( intact)
  2.3 No Manhole
  2.4 Steel Tube/Pipe
  2.5 Sewage only accessible from one side

Fillingpoints are made out of:

• HDPE hoses Ø63 mm ( outside measurements)
• 2 inch or 1,5 inch screw-thread ( only for steel tubes) outside

WARNING NEVER USE PVC CONNECTIONS ( ONLY PVC VENTILATIONS !!)

• • When connections are made make sure that these jobs are done properly, while during foaming some
  additional pressure can/will be built up
  
  • Connections to houses/buildings must be properly been blocked/closed
  
  • A sewage line/tube/pipe should not be longer then 50 meters. If the length is longer please contact us
  
  • You can only foam from Manhole to Manhole
  
  • Narrowing of the pipe/tubes/lines etc should not be present. If so contact us
  
  • Their should not be any closed manholes into a sewage line/tube/pipe

1. Possibilities for fillingpoints

1.1 Manhole that will be taken away
• Connect a HDPE hose Ø50mm or Ø63 mm ( outside measurements) of 3 meter into a sewage pipe.
• Make sure that the filling point is above ground level.
• Fill the Manhole with concrete till approx 40 cm above the edge of the sewage pipe.
• Leave this construction for a minimum of 2 days to harden out

1.2 Manhole that will be taken away with more connections
• Connect a HDPE hose Ø50mm or Ø63 mm ( outside measurements) of 3 meter into a sewage pipe.
• Make sure that the filling point is above ground level.
• Fill the Manhole with concrete till approx 40 cm above the edge of the sewage pipe.
• Leave this construction for a minimum of 2 days to harden out

1.3 Manhole that should be kept in good order ( intact)
• Connect a HDPE hose Ø50mm or Ø63 mm ( outside measurements) of 3 meter into a sewage pipe.
• Make sure that the filling point is above ground level.
• Make a hose connection to fix the HDPE hose at the place where the wall will be made.
• Make a brick wall with waterresistant cement to secure a waterproof construction
• Leave this construction for a minimum of 2 days to harden out

1.4 No Manhole
• Connect a HDPE hose Ø50mm or Ø63 mm ( outside measurements) of 3 meter into a sewage pipe.
• Make sure that the filling point is above ground level.
• Make a hose connection to fix the HDPE Hose at the place where the wall will be made.
• Make a brick wall with waterresistant cement to secure a waterproof construction
• Leave this construction for a minimum of 2 days to harden out

OR

• Make a hole in the sewage pipe
• Connect a HDPE hose Ø50mm or Ø63 mm ( outside measurements) of 3 meter into a sewage pipe.
• Make sure that the filling point is above ground level.
• Fill the hole with concrete
• Leave this construction for a minimum of 2 days to harden out

1.5 Steel Tube/Pipe
• Weld a 1,5 inch or 2 inch pipe with outside thread onto the steel tube at the end where the pressure is placed ( filling point)

1.6 Sewage only accessible from one side
• Build a brick wall with an opening at the bottom for the removal of water, this can also be used as a ventilationpoint
• Bring a HDPE hose through the opening at the bottom till the end of the sewage pipe
• Make sure that the filling point is above ground level.
• Leave this construction for a minimum of 2 days to harden out

2. Possibilities for ventilation

2.1 Manhole that will be taken away
• Nothing need to be done the manhole will operate as a vent pipe.
• This construction has less back-pressure then all other constructions
• Water needs to be pumped out in all cases

2.2 Manhole that should be kept in good order ( intact)
• Connect a pipe at the bottom as a vent pipe, through which the sewage can be pumped empty. This will operate as a vent pipe.
• Make sure that the vent point is above ground level.
• Fill the hole with concrete till approx 40 cm above the edge of the sewage pipe.
• Leave this construction for a minimum of 2 days to harden out


2.3 No Manhole
• Connect a pipe at the bottom as a vent pipe, through which the sewage can be pumped empty. This will operate as a vent pipe
• Make sure every vent pipe is above the ground level
• Make a brick wall with waterresistant cement to secure a waterproof construction
• Leave this construction for a minimum of 2 days to harden out

2.4 Steel Tube/Pipe
• Connect a pipe at the bottom as a vent pipe, through which the sewage can be pumped empty. This will operate as a vent pipe
• Make sure every vent pipe is above the ground level
• Make a brick wall with waterresistant cement to secure a waterproof construction
• Leave this construction for a minimum of 2 days to harden out

OR

• Make a hole in the sewage pipe
• Connect a HDPE/Tyleen hoses to the bottom of the sewage pipe as a vent
• Make sure that the filling point is above ground level.
• Fill the hole with concrete
• Leave this construction for a minimum of 2 days to harden out


2.5 Sewage only accessible from one side
