2. Use of Quick-Lock Mini
2.1. Preparation
2.1.1. Inspecting the pipe
Before using the Quick-Lock system, it is necessary to inspect the pipe/ducts due
to be repaired and verify whether repair using Quick-Lock is possible.
There must be at least one access point available via a manhole or an inspection
opening.
It is necessary to verify the possibility of transporting a packer with a sleeve into
the pipe/duct.
2.1.2. Cleaning and preparing the pipe based on the application
• The pipe to be repaired must always be cleaned with a high-pressure jet
before installing Quick-Lock.
• Hardened sedimentation, roots and protruding connecting pieces must be
removed with appropriate milling tools.
• The pipe should have no obstructions that may restrict movement.
• There must be no solids such as sand, gravel, hardened deposits or
waste water solids around the damaged area.
• Part 5 of DWA-M 143 prohibits works from being done in waste water,
which means the pipe section must be closed off. Depending on the amount of
water, bypassing may be necessary.
• In the case of high-pressure cleaning, do not use other cleaning equipment
since it may worsen the damage.
• The area to be repaired should be visually inspected and documented
after cleaning.
