A seal, system and method for sealing a connection between adjacent barrier members each having a channel along one edge and flange along an opposed edge sized to be received within a corresponding channel of an adjacent barrier member. The seal comprises an elongate core having an opening extending longitudinally therealong and a plurality of fins extending therefrom. The system includes the seal and a wiper sized to surround the flange. The method comprises locating the wiper about the flange and the seal within the channel, engaging the flange within the channel and moving the second barrier member in a downward direction with the wiper below the channel of the second barrier member so as to remove and prevent debris from entering the connection between the channel and the flange.
1. A seal for sealing an elongate member within an elongate channel, the seal comprising:
an elongate core having an opening extending longitudinally therealong, said elongate core having a substantially rectangular cross-section having four corners; and
a plurality of fins extending longitudinally from said elongate core, wherein said plurality of fins comprises a pair of fins proximate to each corner of said rectangular cross-section of said elongate core, each of said pair of fins comprising at least one long fin and at least one short fin extending from said elongate core separated by a slot, wherein said long fin and said short fin are operable to be independently flexible of each other.
2. The seal of claim 1 wherein said opening comprises a central cavity extending along a central axis of said elongate core connected to an exterior of said elongate core by a slot.
3. The seal of claim 1 wherein said plurality of fins extend substantially radially from said elongate core.
4. The seal of claim 1 wherein said elongate core is substantially defined by first and second long sides having first and second short sides extending therebetween.
5. The seal of claim 1 wherein said long fins extend from said short sides proximate to said short fins.
6. The seal of claim 5 wherein said long and short fins extend angularly from said elongate core.
7. The seal of claim 5 wherein each long fin has a corresponding short fin.
8. The seal of claim 7 wherein each long fin extends from said central core substantially parallel to its corresponding short fin.
9. The seal of claim 1 wherein said seal is formed of a substantially flexible material.
10. A system for sealing a connection between adjacent barrier members, each barrier member having a first edge defining a channel and an opposed second edge defining a flange, the flange being sized and shaped to be slidably engaged within a corresponding channel of an adjacent barrier member, the system comprising:
a seal for sealing said flange within said channel, said seal comprising:
an elongate core having an opening extending longitudinally therealong; and
a plurality of fins extending longitudinally from said elongate core; and
a wiper sized to slidably and sealably surround said flange proximate to a bottom edge of said channel having a top edge abuttable against said channel for removing debris from adjacent to said flange.
11. The system of claim 10 further including an edge protector comprising a body having a shape corresponding to said channel of said barrier members being locatable between said channel and said wiper and having an extend portion sized and located to be received within an open end said cavity of said seal located within said channel so as to close said open end of said cavity.
12. A method of sealing interconnections between adjacent panel members in a barrier, each barrier member having a first edge defining a channel and an opposed second edge defining a flange, the flange being sized and shaped to be slidably engaged within a corresponding channel of an adjacent barrier member, the method comprising:
locating a first barrier member within a soil formation;
slidably and sealably locating a wiper about said flange of said first barrier member;
applying a seal within said channel of a second barrier member, said seal comprising an elongate core having an opening extending longitudinally therealong and a plurality of fins extending longitudinally from said elongate core;
engaging said channel of said second barrier member with said flange of said first barrier member; and
moving said second barrier member in a downward direction with said wiper below said channel of said second barrier member so as to remove and prevent debris from entering the connection between said channel and said flange.
13. The method of claim 12 further comprising locating an edge protector between said wiper and said channel of said second barrier member, said edge protector comprising a body having a shape corresponding to said channel of said barrier members and an extend portion received within an open end said cavity of said seal so as to close said open end of said cavity.
