Removable and replaceable anchored tunnel gasket

A cast-in-place gasket for an associated concrete structure, the gasket comprising:

• a gasket body formed from a resilient material, the body including in cross-section a base wall, a first side wall, a second side wall and a top wall;
• a first anchor member protruding from the first side wall of the gasket body and located adjacent the base wall;
• a second anchor member protruding from the second side wall of the gasket body and located adjacent the base wall;
• wherein a face of the first and the second anchor members is at least one of planar and rounded;
• and
• wherein the first and second anchor members are sized such that the gasket body is selectively detachable from a groove defined in the associated concrete structure by the gasket.

A cast-in-place gasket for an associated concrete structure, the gasket comprising:

• a gasket body formed of a resilient material, the gasket body having a longitudinal axis and including in cross-section a base wall, a first side wall, a second side wall, and a top wall;
• a first anchor member protruding radially from the first side wall of the gasket body and located adjacent the base wall and running along the longitudinal axis of the gasket body;
• a second anchor member protruding radially from the second side wall of the gasket body and located adjacent the base wall and running along the longitudinal axis of the gasket body;
• wherein the first and second anchor members include a face which is at least one of planar and rounded;
• and
• wherein the first and second anchor members are sized such that the gasket body is selectively detachable from side channels defined in the associated concrete structure during the casting in place of the gasket.

A method for replacing a defective gasket in a concrete structure comprising:

• providing a gasket body including first and second anchor members extending, respectively, from the gasket body on opposed side walls of the gasket body adjacent a base wall thereof;
• casting the concrete structure around the gasket body;
• forming a groove in the concrete structure with the gasket body;
• forming side channels in the groove with the first and second anchor members;
• removing the gasket body from the groove and the anchor members from the side channels, wherein the gasket body comprises a resilient material and the first and second anchor members are so sized that the gasket body is detachable from the concrete structure in an intact manner;
• and
• providing a replacement gasket body including first and second anchor members;
• and
• inserting the gasket body into the groove and the anchor members into the side channels of the concrete structure.
