Possible Constructions for connections for Bacel 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
