Method of locating liner within sewer pipe
View Patent ↗A method of inserting a cured in-place pipe from a cleanout includes positioning a lining along a portion of a length of a bladder, wherein the lining is frangibly connected to the bladder, inserting the bladder through the cleanout, to a position wherein the lining is within the pipe and does not block the pipe.
1. A method of making a cured-in-place pipe repair to a pipe in fluid communication with an access pipe and having an area in need of repair, the method comprising:
providing an elongated bladder tube having a first bladder tube end and a second bladder tube end;
providing an elongated liner tube having a first liner tube end and a second liner tube end;
positioning the first liner end tube end within the bladder tube such that the liner tube is spaced apart from the first end of the bladder tube by a predetermined distance;
securing the first liner tube end of the liner tube within the bladder tube using an adhesive or solvent;
impregnating the liner tube with a material capable of curing and hardening;
inverting the bladder tube through at least a portion of the access pipe to an inverted position with the liner tube pressed against the pipe adjacent the area in need of repair in the pipe;
wherein the predetermined distance enables the liner tube to line the area in need of repair in the pipe without the liner tube blocking flow through the pipe or the access pipe;
permitting the uncured resin to cure and harden; and
removing the bladder tube to leave the liner tube cured in place at the area in need of repair within the pipe.
2. The method of claim 1 wherein the bladder tube is closed about the second end.
3. The method of claim 1 wherein the pipe is a lateral sewer pipe and the access pipe is a cleanout pipe in communication with the atmosphere.
4. The method of claim 1 wherein the step of securing the liner tube within the bladder tube is performed in at a jobsite.
5. The method of claim 1 wherein the liner tube is secured within the bladder tube by removably attaching the liner tube directly to the bladder tube.
6. The method of claim 1 wherein the liner tube is positioned completely within the bladder tube in the positioning step.
7. A method of making a cured-in-place pipe repair to a pipe in fluid communication with an access pipe and having an area in need of repair, the method comprising:
providing an elongated bladder tube having a first bladder tube end and a second bladder tube end;
providing an elongated liner tube having a first liner tube end and a second liner tube end;
positioning the first liner end tube end within the bladder tube such that the liner tube is spaced apart from the first end of the bladder tube by a predetermined distance;
securing the first liner tube end of the liner tube within the bladder tube using an adhesive or solvent;
impregnating the liner tube with a material capable of curing and hardening;
attaching the first end of the bladder tube to a launching device;
positioning the launching device in an operative position remote from the lateral pipe;
inverting the bladder through at least a portion of the access pipe to an inverted position with the liner tube pressed against the pipe adjacent the area in need of repair in the pipe;
wherein the predetermined distance enables the liner tube to line the area in need of repair in the pipe without the liner tube blocking flow through the pipe or the access pipe;
permitting the uncured resin to cure and harden; and
removing the bladder tube to leave the liner tube cured in place at the area in need of repair within the pipe.
8. A method of making a cured-in-place pipe repair to a pipe comprising:
providing an elongated bladder tube having a first bladder tube end and a second bladder tube end;
providing an elongated liner tube having a first liner tube end and a second liner tube end;
positioning the first liner end tube end within the bladder tube such that the liner tube is spaced apart from the first end of the bladder tube by a predetermined distance;
securing the first liner tube end of the liner tube within the bladder tube using an adhesive or solvent;
impregnating the liner tube with a material capable of curing and hardening;
inverting the bladder tube through the pipe to an inverted position with the liner tube pressed against the pipe adjacent the area in need of repair in the pipe;
wherein the predetermined distance enables the liner tube to line the area in need of repair in the pipe without lining the pipe between the area in need of repair and the first end of liner tube as positioned during the inverting step;
permitting the uncured resin to cure and harden; and
removing the bladder tube to leave the liner tube cured in place at the area in need of repair within the pipe.
