Patent number: 11248358Abstract: A geogrid and a manufacturing method thereof. The geogrid comprises multiple ribs, and the multiple ribs are connected to each other at multiple junctions to form multiple cells. At each junction, two or more adjacent ribs of the multiple ribs are inserted into each other via inserts, and each junction is covered by a plastic material. The geogrid can easily be extended to a present state at a construction site, prevent tearing of apertures, prevent soil from leaking from the apertures, and prevent the inserts from rusting or corroding. Since the plastic material, the ribs, and the inserts are bonded to each other, separation strength at the junction is markedly increased. Preferably, an end portion of the insert is completely covered by the plastic material to form an end cap, and the plastic material and the ribs and the inserts are bonded to each other to form columns.Type: GrantFiled: June 13, 2018Date of Patent: February 15, 2022Inventors: Man Zhang, Yongkong Wei

Patent number: 11231128Abstract: 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.Type: GrantFiled: June 28, 2019Date of Patent: January 25, 2022Assignee: 1552818 ONTARIO LIMITEDInventor: Geoff Weyman Connors

Patent number: 11047513Abstract: In order to reduce or remove the potential risk of heat damage in the absence of cooling jackets when joining lined pipe sections, each lined pipe section is provided with an insulatory sleeve which is disposed between the host pipe and the respective liner. The sleeves provide discrete thermal protection to the ends of the liners and, where applicable, electrofusion welds between an electrofusion fitting and the liners. The sleeves are first located in the ends of the host pipes which are then lined by drawing the liners through the host pipes via a reduction die to reduce their external diameter. The liners are then reverted towards their original dimensions resulting in a tight fitting against the internal surface of the host pipes and of the insulatory sleeves thereby compressing the insulation material.Type: GrantFiled: May 23, 2016Date of Patent: June 29, 2021Assignee: Pioneer Lining Technology LimitedInventor: Stephen Barnes
