Description

System of installing a liner in a pipe system
The invention relates to a system for installing a liner in a branch position of a pipe system, in particular in a sewer or a drain pipe system of an apartment. More particularly the invention relates to the system according to the preamble of the independent system claim.
For repairing and renovating sewer or drain pipe systems of apartments one generally used method is to install a liner in the pipe. From prior are many different methods and systems are known to install the liner. Typically in these methods are used and the systems comprise a device to be pulled or pushed through the pipes and to located the liner to its installation position in the pipe. Usually the liner is normally heat curable but soft and flexible before and during installation. When the liner is in the installation position in the the device is used to press the liner against the inner walls of the pipe, e.g. by means of an inflatable bladder, and then cure the liner by heat. Simultaneously when the bladder is inflated and it presses the liner against the walls of the pipe, the liner is cured for example by steam or hot air or the liner is cured by the reaction of epoxy and resin i.e. in so called ambient cure. After the curing the device is removed from the pipe and a hard and resistant liner is provided inside the pipe and thus the pipe is repaired or renovated.
Many of from the prior art known systems are large, complicated and suitable to be used in installing a liner in communal sewer pipes or drains or in pipes or drains otherwise having large diameters.
In EP patent publication 2499414 is disclosed an apparatus for installing a liner in a pipe including pipe bends, which apparatus comprises proximal collar fitting and a distal collar fitting interconnected by a small cross-sectional area flexible tube or rod, an inflatable bladder one end of the inflatable bladder being secured to the proximal collar fitting and the other end of the inflatable bladder being secured to the distal collar fitting with the small diameter flexible tube or rod disposed inside the interior of the inflatable bladder, a push-pull-turn hose with a proximal end and a distal end, which distal end of said a push-pull-turn hose is connected in a releasable way to the proximal collar fitting and said push-pull-turn hose is in fluid communication with the interior of the inflatable bladder. As an advantageous feature this publication discloses that there are no other components than the flexible tube or rod in the interior of the inflatable bladder. In this EP publication is also disclosed a toolkit for installing a liner in a pipe that includes pipe bends, which toolkit comprises: a push-pull-turn hose with a coupling half at its distal end, a proximal collar fitting with coupling halves at each of two opposite ends, which distal end of the push-pull turn hose is to be connected in a releasably to the proximal collar filling, a distal collar fitting with a coupling half at one end, and a small cross-sectional area flexible tube or rod with a coupling half at both opposite ends that matches the coupling halves on the collar fittings, and inflatable bladder, which is configured for having one end secured to the proximal collar fitting ant the other end secured to the distal collar filling with the small diameter flexible tube or rod disposed inside the interior of the inflatable bladder and upon assembly of the toolkit, the pus-pull-turn hose is configure for fluid communication with the interior of the inflatable bladder. In this publication also a method for installing a liner is disclosed, which method comprises providing a proximal collar fitting and a distal collar fitting interconnected by a flexible and small cross-sectional area tube or rod to create a flexible tube or rod assembly, providing an inflatable bladder with two open ends inserting said flexible tube or rod assembly into said inflatable bladder .securing one open end of said inflatable bladder to said proximal collar fitting, securing the other open end of the inflatable bladder (to said distal collar fitting to form a bladder arrangement, providing a push-pull-turn hose and connecting one end of said push-pull-turn hose to said proximal collar fitting, placing a curable liner over said bladder arrangement , inserting said bladder arrangement with said curable liner into said pipe , moving said bladder arrangement with said curable liner into a desired position and orientation into said pipe by pushing, pulling and/or turning said bladder arrangement with said push-pull-turn hose.
In known methods of installing a liner in an apartment building to repair or renovated branches of the pipe system the device is pulled or pushed through the main line to the location of the branch to be repaired or renovated. This often means cumbersome work as the distances may be long and the pipes may have many bends and turns. Thus these known methods are relatively difficult and slow and difficult to use.
An object of the present invention is to provide an improved system installing a liner in a pipe, in which the problems and disadvantages of methods and systems known from prior art are eliminated or at least minimized.

The attachment opening 32 is provided with threads 42 that extends on at least on part of length of the opening 32 on the inner surface of the opening 32 on each end of the opening 32 for connecting the push-pull-turn rod 25 (figure 1) and the connecting rod (figure 1). The outer surface of the connecting part is provided with a recess 43.
In figure 5 is shown schematically a simplified example of the system 10 according to the invention in a drain pipe system of an apartment having more than one story i.e. having at least two floors 51 at a distance from each other. The main drain pipe 52 passes in vertical direction through the floors and in the floors 51 are located the side drain pipes 53 leading from a floor drain 54 or corresponding opening for waste water to the main drain pipe 52, which then guides the waste waters to the sewer pipe system. Branch positions are formed, when the side drain pipes 53 meet the main drain pipe 52. Angle a between the main drain pipe 52 and the side drain pipe 53 is 45 0 - 135 °. Diameter D52 of the main drain pipe 52 can vary between 70 - 300 mm and diameter D53 of the side drain pipe 53 can vary between 70 - 300 mm.
In the example of the figure the system 10 of installing a liner in a pipe is located in the side drain pipe 53 of the upper floor 51 for installing the liner in the branch position of the side drain pipe 53 and the (vertical) main drain pipe 52. The bladder 11 is located such that the foot part 12 of the T-shaped bladder 11 is located in the side drain pipe 53 the foot part 12 extending longitudinally in the longitudinal direction of the side drain pipe 53 and the shoulder parts 13 of the T-shaped bladder 11 extend vertically each in one direction from the side drain pipe 53 in the main drain pipe 52.
According to the method in accordance with the invention the system 10 is located into the pipe system via the floor drain 54 and into the side drain pipe 53 for installing a liner in a branch position of a pipe system.
