Method and Apparatus for Repairing a Pipe Junction
An assembly and method of sealing a junction of a pipe and a second structure are provided. The assembly includes a pipe liner having a tubular portion and a brim portion, and a mechanical anchor adapted to secure the brim portion of the pipe liner to the second structure. The assembly may further include a compression gasket for placement between the pipe liner and the pipe or second structure. The compression gasket may comprise a hydrophilic material, a hydrophobic material, or a compressible material. The methods of using the assembly include, but are not limited to, the use of a cured-in-place pipe liner.
1 . A method of sealing a junction of a pipe and a second structure comprising:
providing a pipe liner having a tubular portion and a brim portion;
placing the tubular portion of the pipe liner against an interior wall of the pipe;
placing the brim portion against the second structure; and
securing the brim portion to the second structure using a mechanical anchor.
2 . The method of claim 1 , further comprising securing the mechanical anchor to a compression gasket.
3 . The method of claim 2 , further comprising placing a compression gasket between the brim portion of the pipe liner and the second structure.
4 . The method of claim 2 , wherein the compression gasket comprises a hydrophilic material, a hydrophobic material, or a compressible material.
5 . The method of claim 1 , wherein the pipe is a lateral sewer pipe and the second structure is a main sewer pipe.
6 . The method of claim 5 , wherein the securing step comprises using a sewer robot to drive the mechanical anchor at least partially through the brim portion and the main sewer pipe.
7 . The method of claim 11 , wherein the pipe liner is a cured-in-place pipe liner.
8 . The method of claim 7 , wherein the securing step comprises driving the mechanical fastener through the brim portion and at least a portion of the second structure after a resin impregnated within the cured-in-place pipe liner has hardened.
9 . The method of claim 8 , further comprising inserting the mechanical anchor through a compression gasket placed between the brim portion of the pipe liner and the second structure.
10 . The method of claim 9 , wherein the pipe is a lateral sewer pipe and the second structure is a main sewer pipe.
11 . A junction of a pipe and second structure sealed by a process comprising the steps of:
providing a pipe liner having a tubular portion and a brim portion;
placing the pipe liner against an interior wall of the pipe;
placing the brim portion against the second structure; and
securing the brim portion to the second structure by inserting a mechanical anchor through the brim portion and at least partially through the second structure.
12 . The junction of claim 11 , wherein the pipe liner is a cured-in-place pipe liner.
13 . The junction of claim 12 , the process further comprising driving the mechanical fastener through the brim portion and at least a portion of the second structure after a resin impregnated within the cured-in-place pipe liner has hardened.
14 . The junction of claim 13 , the process further comprising inserting the mechanical anchor through a compression gasket placed between the brim portion of the pipe liner and the second structure.
15 . The junction of claim 14 , wherein the pipe is a lateral sewer pipe and the second structure is a main sewer pipe.
16 . A method of sealing a junction of a pipe and a second structure comprising:
providing a resin impregnable pipe junction liner having a tubular portion and a brim portion;
placing the tubular portion of the pipe liner against an interior wall of the pipe;
placing the brim portion against the second structure; and
securing the brim portion to the second structure by inserting a mechanical anchor through the brim portion and at least partially through the second structure.
17 . The method of claim 16 , further comprising securing the mechanical anchor to a compression gasket.
18 . The method of claim 17 , further comprising placing a compression gasket between the brim portion of the pipe liner and the second structure.
19 . The method of claim 17 , wherein the compression gasket comprises a hydrophilic material, a hydrophobic material, or a compressible material.
20 . The method of claim 16 , wherein the pipe is a lateral sewer pipe and the second structure is a main sewer pipe.
