epros® DrainLCR-S: Lateral Connection Repair in Main Sewer Pipes
epros® DrainLCR-S is a trenchless repair system that seals main/lateral interfaces by installing a glass-reinforced hat profile or an LCR-S liner from the main pipe into the lateral up to 600 mm. It supports main DN 135–600 and lateral DN 100–200 at 30°–90° connection angles.
What is epros® DrainLCR-S and who is it for?
DrainLCR-S is both a device and a method for repairing house lateral connections from within the main line in municipal and industrial sewer networks. It permanently seals junctions using either a hat profile (seals at the rim in the main) or an LCR-S liner (repairs the main section and a defined length of the lateral).
How does DrainLCR-S work step-by-step?
DrainLCR-S positioning uses an on-packer camera, a rotary drive and telescopic wheel sets to locate the junction precisely while maintaining alignment. A compressed-air pathfinder lifts the packer basket into the junction to lock position.
DrainLCR-S inversion & curing starts with time-delayed inflation of the packer, then controlled inversion of the lateral hose and liner/hat profile. A clear acoustic signal confirms full inversion; after curing, the packer is deflated and removed.
How does the epros® DrainLCR-S work?
Trelleborg Pipe Seals Duisburg is among the leading specialist companies in innovative
technologies for the upkeep of sewer systems.
The brand name epros®DrainSystems stands for 20 years of experience, continuous research and
further development of technical systems for modern trenchless repair of pipelines in sewer
systems, buildings and industries.
The epros® DrainLCR-S system is both a pipe repair device and a method for the lateral connection repair (house lateral connections) of main pipes in public infrastructure networks.
It repairs and permanently seals main/lateral interfaces and lateral connections (DN 100 – DN 200) by installing either a LCR-S hat profile or an LCR-S liner from the main pipe (DN 135 – DN 600) up to a length of 600 mm.
The LCR-S hat profile seals the main/lateral junction in the main line just with its rim. The LCRS liner in the main pipe is designed similar to a short liner and will at the same time repair a defined length of the lateral pipe.
In both cases, the forming element is an inflatable pro-formed hose that serves the same function.
This inflatable hose in the form of a cylinder (packer hose), is additionally equipped with another cylinder located at the mid-point (the lateral hose) at an angle of 45° or 90° to the axis of the packer.
Prior to installation, this lateral hose together with resin-impregnated LCR-S Liner or LCR-S hat profile is re-inverted into the packer hose.
Sucking out the complete air out of the packer hose and the branch hose generates a sort of vacuum, which allows to defend the repair material inside the packer hose (LCR-S Liner or LCR-S hat profile) from possible dislocation during the insertion into the pipe.
This is usually performed by means of a push rod reel system, and in case of short distances and small pipe diameters – with a pneumatic push-rod attached to the packer.
In case of both applications precise determination of damaged area as well as the correct positioning of the packer are imperative. The following devices are used for these purposes:
First, a camera is mounted on the packer. This camera helps to locate the junction of the house connection pipe to the main pipe.
The packer is equipped with a telescopic wheel system and a rotary drive that enables the user to rotate it axially in the damaged area and so to locate the junction whilst the wheel systems braced inside the pipe maintain the axial position.
The packer rod is featured by a lifting mechanism with a compressed air cylinder (pathfinder) pushing
a sort of ring (the packer basket) into the main/lateral junction area. This packer basket is located underneath the packer hose directly at the packer hose/ branch hose link and its lifting
mechanism is controlled via an operator panel from outside the pipe.
It is the function of the pathfinder to achieve the correct positioning inside the sewer pipe at the damaged lateral connection and to lift up the basket directly into the junction.
The LCR-S Packer, prepared in this way, is then pushed into the damaged area.
When the packer has reached its final position, the inflation process is started with the packer hose and after a given time delay continued with both, the lateral hose and liner, now inverting into the connection pipe whilst the lifting basket is driven back. The time-delayed inflation is controlled by means of a stiff cable, inserted and braked using a reeling box.
Partially inflated packer after positioning After the lateral packer hose has been completely inverted, a clear acoustic signal is given to indicate that the inversion process successfully is finalized.
After curing of the liner, the packer is blown off and removed from the repair area.
Benefits at a glance
- Application area
Mainline DN 130 – DN 600
Lateral DN 100 – DN 200
30° – 90° - Portable modular system:
Light mobile unit, can be transported also in a small vehicle - Value for money:
Low investment costs, because only packer sizes that are really needed must be purchased.
Fast installation allows multiple installations per day - User-friendly handling:
LCR packers can be converted into other sizes, according to your needs. This allows as much flexibility in application as possible.
Our appropriate resin systems are designed to have both comfortable pot times and quick cure times as soon as the chemical reaction has been started. This helps to reduce time pressure, increases work security and leads to better product quality. - Safe installation:
1. Starting the inflation process is possible only after the LCR basket is locked in place.
2. Only a complete finalized inflation process triggers the acoustic signal. - Clean Technology:
Trenchless technology. No voc’s, no styrene, no environmental or health issues - Quality and Sustainability:
No shrinkage. Glass reinforced hat profiles and liners ensure excellent mechanical properties and a good rehabilitation result with a long lifetime.
