Patent attributes
A conduit weighting device has a container to contain ballast. The container is formed from flexible sheet material and has a top opening to receive the ballast. The device has flaps extending from respective opposite edges of the top opening of the container. The container forms an underside channel sized and shaped to receive a conduit for conforming placement of the conduit weighting device on the conduit to weight the conduit. The flaps are sized and shaped: when in an open arrangement, to extend beyond edges of a trench containing the conduit to hold open the top opening while receiving the ballast material; and when in a closed arrangement, to close the top opening of the container. The weighting device may be placed on an entrenched conduit before filling, and then filled in place with locally-available backfill. The device may be transported to the site in a collapsed compact form.
