摘要： Methods and devices for sealing and/or gripping concrete strengthening tendons. Some embodiments provide a method of forming a seal between an encapsulated anchor and a sheath of a tendon engaging the encapsulated anchor. Other embodiments provide a splice for forming a seal around a discontinuity in the sheath of a concrete tensioning tendon. Some embodiments provide a seal assembly for forming a seal between a tubular extension and a sheath of a tendon to protect an exposed portion of the tendon contained within the tubular extension. Some embodiments also provide a method of forming a fluid tight seal between tubular extension and a sheath of a tendon, while other embodiments provide a method of gripping the sheath of a tendon with a tubular extension to prevent the sheath from moving relative to the extension.

摘要： A modular fire prevention flooring system includes a plurality of fire prevention flooring planks. Each plank is generally tubular and forms a drain channel. Fluids spilled onto the upper surface of the flooring system may drain through a plurality of drain holes formed in the upper surface of the planks. The planks may further include a metal filler positioned within the drain channels to stop combustion of burning fluids spilled into the drain channels. The metal filler may break up burning liquids and remove heat therefrom. In some embodiments, a purging fluid may be flowed through the planks to purge any spilled fluids therefrom.

摘要： A land-based drilling rig includes a first substructure and a second substructure, the second substructure being positioned generally parallel to the first substructure. The land-based drilling rig also includes a drill rig floor coupled to the first and second substructures, the drill rig floor including a V-door. The side of the drill rig floor has the V-door defining a V-door side of the drill rig floor, where the V-door side of the drill rig floor is parallel to the first substructure. The first and second substructures pivotably support the drill rig floor. The land-based drilling rig also includes a mast, the mast mechanically coupled to one or more of the first substructure, the second substructure, and the drill rig floor. The mast is pivotably coupled to one or more of the first substructure, the second substructure, and the drill rig floor by a mast pivot point. The mast includes a V-door side, the V-door side of the mast parallel to the first or second substructure. In addition, the land-based drilling rig includes a mast hydraulic lift cylinder coupled to the mast at a mast lift point and a choke manifold, the choke manifold positioned on the drill rig floor.

摘要： A walking mud handling system may include a walking mud tank and a plurality of hydraulic walkers coupled to the walking mud tank. Each hydraulic walker may include a walking foot, a hydraulic lift, and a sliding actuator. The hydraulic lift may include a hydraulic cylinder coupled to the walking foot such that extension of the hydraulic cylinder extends the walking foot into contact with the ground. The sliding actuator may include one or more hydraulic cylinders coupled to the walking foot such that extension of the sliding actuator moves the walking foot laterally relative to the hydraulic lift.
