Lateral Interface Device Extended Bladder
The invention subject of this disclosure is for an in situ pipe repair lateral interface device comprising a housing component comprising fluid inflation components and a bladder mounting flange and a housing extension fluid sealably attachable to the housing and containing a heatable and inflatable bladder that may be attached to the bladder mounting flange.
1 . An in situ pipe repair lateral interface device comprising:
a) a housing component comprising fluid inflation components and a bladder mounting flange; and
b) a housing extension fluid sealably attachable to the housing and containing a heatable and inflatable bladder that may be attached to the bladder mounting flange.
2 . The device of claim 1 further comprising a flexible fluid sealable connection between the housing and the housing extension.
3 . The device of claim 1 further comprising a motor structure having a hinged relationship to the housing and that positions and stabilizes the housing and housing extension within the pipe.
4 . The device of claim 1 further comprising a connecting component between the housing component and the housing extension.
5 . The device of claim 4 further comprising a hinged connecting component.
6 . The device of claim 1 further comprising a tether attached to the end of the bladder for retracting the tether from a lateral pipe and further comprising the tether extending through the housing extension.
7 . An in situ pipe repair lateral interface repair device comprising:
a) a housing component comprising fluid inflation components and electrical conductivity components and a bladder mounting flange; and
b) an inflatable and heatable bladder fluid sealably attached to the bladder mounting flange; and
c) a housing extension fluid sealably attachable to the housing and containing a portion of the inflatable and heatable bladder during storage and transportation of the bladder to a lateral interface.
8 . A method of in situ repair of the interface between a main pipe and a lateral pipe comprising:
a. placing a repair material comprising a thermally responsive material onto a bladder;
b. inverting the bladder with the repair material into a housing and housing extension further comprising the housing and housing extension dimensioned to hold the bladder and repair material;
c. positioning the bladder within the housing utilizing a motor structure;
d. everting the bladder and repair material into a lateral pipe by adding fluid to the housing;
e. pressing the repair material to the lateral pipe;
f. resistively heating the bladder; and
g. retracting the bladder from the lateral pipe using a tether.
9 . The method of claim 8 further comprising evacuating the fluid.
10 . A device for the in situ repair of the interface between lateral pipe and main pipes comprising an inflatable and heatable bladder greater than 2 ft and less than 6 ft in length.
11 . The device of claim 8 further comprising an inflatable and heatable bladder greater than 3 ft and less than 10 ft in length.
