The lip is configured to support the cover thereon, and the skirt further includes an inwardly-extending channel positioned adjacent to the lip.
Claims23
A system comprising:
- a backfill protector including a skirt having an opening configured to receive a cover therein and a lip extending around a perimeter of the opening, the lip being configured to support the cover thereon, the skirt further including an inwardly-extending channel positioned adjacent to the lip;
- and
- a cover including at least one cam lock connector configured, when the cover is positioned in the opening, to engage an underside of the channel and apply a compressive force to the channel to thereby secure the cover in place.
A system comprising:
- a backfill protector including a skirt defining an inner cavity, the backfill protector having an opening configured to receive a cover therein and further having a channel extending around a perimeter of the opening, the channel being configured to support the cover thereon, wherein the channel is open at its radially outer end to enable the channel to receive material therein, wherein the channel has a height less than about 12% of a height of said backfill protector, and wherein the channel extends into said inner cavity such that a connector can engage said channel and apply a compressive force thereto;
- and
- a cover including at least one cam lock connector configured, when the cover is positioned in the opening, to engage an underside of the channel and apply a compressive force to the channel to thereby secure the cover in place.
A method for installing a system comprising:
- accessing a sump;
- positioning a backfill protector above the sump, the backfill protector including a skirt having an opening configured to receive a cover therein and a channel extending around a perimeter of the opening, the channel being configured to support the cover thereon and being open at its radially outer end, and wherein the channel has a height less than about 10 times a thickness of a material defining the channel;
- positioning backfill material about the backfill protector such that the backfill material at least partially enters the channel;
- and
- positioning a cover in said opening, said cover including at least one cam lock connector configured, when the cover is positioned in the opening, to engage an underside of the channel and apply a compressive force to the channel to thereby secure the cover in place;
- and
- said cam lock connector applying a compressive force to the channel to thereby secure the cover in place.
