Trelleborg LCR-B System
by bad smells, moist walls, mold and, in worst case scenarios, structural damage.
●In the past, repairs to such damaged downpipes and sewers were limited to either patch repairs or to the installation of full-length liners. To repair a lateral connection, one would need to hack into a wall or excavate the ground – causing inconvenience to residents in the form of noise pollution, dirt and service disruptions. In fact, most current conventional repair methods still require the need for hacking or excavation.
●Trelleborg solves this problem with the innovative Trelleborg LCR-B system for the rehabilitation
of underground house sewers and downpipes in buildings with lateral connections.
●This revolutionary pipe repair system allows lateral connections to be repaired in the same step as
the main pipe without the need to hack into walls or excavate the grounds – thus reducing major inconvenience to the residents.
●In this system, the LCR-B Packer can be introduced into the main pipe via existing access holes, inspection chambers or cleaning eyes, and pushed to the point of repair by means of compressed-air push rods.
●As the LCR-B Packer is exceptionally compact and flexible, it is able to smoothly negotiate 45° bends in a main pipe of DN 100 [4"] and 90° bends in a main pipe of DN 125 [approx. 5"] or bigger.
●A remote-controlled inspection camera which has been inserted into the lateral pipe and pushed up to the lateral connection helps with this packer positioning process. The packer, once it has reached the main/lateral connection to be repaired, needs to be rotated using the air push rods until the LCR-B Hat Profile or LCR Liner (which is mounted onto the packer) is aligned with the connection.
●When this final position has been achieved, the LCR-B Packer can be inflated. This is a cylindrical inflatable pro-formed hose that is equipped at midpoint with another cylindrical hose (bladder), at an angle of either 45° or 90°, for the lateral pipe. As the packer reaches maximum inflation, the lateral bladder inflates, inverting the hat profile or liner into the lateral connection pipe.
●The system operator uses the camera to monitor the process and determine when the inversion is
complete.
●The curing process can then begin.
●After curing, the system operator can use the LCR-B Control Box to apply a vacuum to deflate the LCR-B Packer. The deflated packer can then be removed with the help of the air push rods.
●Benefits at a glance
■FLEXIBLE AND COMPACT
◆This ultra flexible and compact system is able to negotiate 45° or 90° bends in downpipes and sewers as well as can be bent to fit into access holes and inspection chambers – allowing for great accessibility!
■STREAMLINED SETUP & COST EFFECTIVE
◆With a streamlined list of equipment that goes with this system, you’ll be able to cut your investment costs. For example, you simply need to purchase the packers that you actually require. What’s more, the job can be completed by just using air push rods – no remote controlled crawler is needed.
■EASILY TRANSPORTABLE
◆The compact and lightweight mobile unit can even be transported in a small car.
■THERMAL RESISTANT
◆The cured epoxy resin systems used with the LCR-B Hat Profile and LCR Liner boast high thermal resistant properties. Of these, the silicate resins are also fire resistant as they are self-extinguishing.
