Abstract
A liner plate structure, system and method is provided for lining of mine shaft bores, tunnels and the like. The liner plate structure includes a primary plate portion and at least one flange disposed at a side edge of the primary plate portion. A polymer seal element extends along a recess within an exterior surface of the flange.
Claims16
A method of forming a plate structure for use in lining shafts and tunnels, comprising:
- utilizing a liner plate structure with a primary plate having first, second, third and fourth flanges respectively disposed at first, second, third and fourth side edges of the primary plate, each flange including a respective recess that is aligned with the recess of adjacent flanges to produce a continuous recess that circumscribes the liner plate structure;
- applying a seal member to the continuous recess utilizing a plural component material processing technique and in a manner such that the seal member at least partially cures within the recess and is bonded to a portion of the recess and includes an upper portion protruding from the recess;
- wherein subsequent to the applying step a planing device is used to cut the seal material in order to define a final height of the seal member.
A method of forming a plate structure for use in lining shafts and tunnels, comprising:
- utilizing a liner plate structure with a primary plate having first, second, third and fourth flanges respectively disposed at first, second, third and fourth side edges of the primary plate, each flange including a respective recess that is aligned with the recess of adjacent flanges to produce a continuous recess that circumscribes the liner plate structure;
- applying a seal member to the continuous recess utilizing a plural component material processing technique and in a manner such that the seal member at least partially cures within the recess and is bonded to a portion of the recess and includes an upper portion protruding from the recess;
- wherein during the applying step one or more seal forms are located alongside and/or within the recess to define lateral limits for the applied seal member, and wherein the seal forms are removed after application of the seal member.

- abrading at least a bottom surface of the continuous recess to prepare the continuous recess to receive a seal material;
- applying a seal material to the continuous recess utilizing a plural component material processing technique such that the seal material at least partially cures within the recess and bonds to the bottom surface of the recess and includes an upper portion protruding from the recess;
- wherein during the applying step one or more seal forms are located alongside and/or within the recess to define lateral limits for the applied seal material, and wherein the seal forms are removed after application of the seal member.
