LINK-PIPE® PVC Repair Sleeve

Installation procedure:

LINK-PIPE® Repair Sleeves  shall have adequate longitudinal length to span the damaged area and extend at least six (6”) inches into sound pipe on both sides of the damaged section.


 

 

Cleaning

 


All obstructions protruding more than ¼” from the inner surface of the sewer pipe, any loose pipe pieces, and any sharp objects shall be removed. The pipe shall be cleaned and all deposits which may prevent the proper installation of the repair sleeves shall be removed.

Step #1:

Once the repair location has been cleaned from debris, the LINK-PIPE® sleeve is moved into place. In case access is restricted, sleeves are passed through unassembled and put together in the manhole or at the repair location. 


Step #2:

O-rings F are placed into prepared grooves on the sleeve.

Note: Only Manufacturer specified O-ring materials should be used to suit the chemical environment.


Step #3:

For installation, a vertical jack is used to lift the crown segment A until the O-rings are tightly compressed against the host-pipe crown.

 


Step #4:

A horizontal jack is then taken and placed between the side flaps D & C and expanded. The installation process is complete when the flaps snap out and create a smooth circle. Note: Flaps on one side always go out first. The other side follows next with an audible snap. This is the sign of a tight installation.

 

 

 

 

 


Step #5:

Annular space is then pumped full of chemicals or cementitious grout. This completes the repair.

Note:

For sealing infiltration the sealant  used shall be as specified by the Manufacturer. 

For structural repair a resin specified by the Manufacturer shall be used if no infiltrating water is present.  Any infiltration shall be sealed before a sleeve using structural grout is installed.

Step #6:

Verification of installation and sealing shall be produced on a hand-held portable or remote control colour video camera. All pertinent information such as job location, pipe size, and the station of the repair shall be noted on the audio portion of the videotape. Each repair sleeve shall be numbered and identified from manhole to manhole location (section number, joint number, and installation location).
