A system and method for protecting workers, vehicles, and well-heads by enclosing well-site cellars with a series of framed plates. Each plate is perforated and configured for lifting with holes for hoisting the plates. Each plate is lipped to be retained by longitudinal edges of the cellar. A plurality of plates supports a platform for supporting a pipe wrangler adjacent a cellar based wellbore.

A rotomolded lid for a meter box and a method of making the same are provided. The lid is formed in a rotomold process that embeds a pair of rebars within a hollow lid product. Concrete is then poured into the hollow portion and allowed to cure. The end result is a reinforced meter box lid that is configured to handle loads of up to 16,000 lbs. In addition, the presence of the rebars, which are ferromagnetic, allows a metal detector to detect the presence of the lid should it ever be inadvertently covered over or otherwise obscured from view. Furthermore, the central lid portion may also include a passageway covered by a hinged door to permit access to the meter box without having to lift up the lid itself. Another passageway, along with an associated countersunk portion in an upper lid surface, permits a wireless transponder to be positioned therein and connected to meter equipment in the box.

A cover for an underground enclosure may include an upper surface and may include a pattern of bosses, and a first slot and a second slot each disposed on the upper surface. The cover may also include a lower surface opposite the upper surface. A first rib or reinforcement member may be coupled to the lower surface. The first slot may extend into the first rib or reinforcement member. A second rib or reinforcement member may be coupled to the lower surface and aligned with the first rib or reinforcement member. The second slot may extend into the second rib or reinforcement member. The cover may be configured to be lifted by the first slot and the second slot.

A frame system for a manhole covering includes at least one first frame element and one second frame element, each including at least one first connecting surface and/or at least one second connecting surface. The first and second frame elements are connectable to one another in a friction-locked and/or formfitting manner along the opposing first or second connecting surfaces, wherein in the connected state of the first and second frame element at least one joining region is formed between the opposing first connecting surfaces or between the opposing second connecting surfaces. The joining region can be filled using a joining element in such a way that the joined connection of the frame elements is detachable and reproducible wherein the joining element comprises a hot melt adhesive.

Disclosed is a cover for a utility vault and a method for making such covers. The cover is formed from fiberglass reinforcement layers, a low-density core, and a polymer mix matrix. The reinforcement layers include a bottom reinforcement layer, one or more edge reinforcement layers, and a top reinforcement layer. A first portion of the edge reinforcement layer overlaps a portion of the bottom reinforcement layer and a second portion of the edge reinforcement layer overlaps a portion of the top reinforcement layer. The core is positioned between the top and bottom reinforcement layers. The reinforcement layers are formed from fiberglass fabric and may include fiberglass layers whose fibers are oriented quadraxially. The polymer mix impregnates the fabric layers, encases the core, and binds the components together. The polymer matrix includes a thermoset polymer resin.

A manhole includes a device for safely closing and locking the manhole, which has a cylinder with centering pins that is attached to a slab and is rotatable with an operating key acting on the pins, and further includes an anti-burglary block, which in locked position is positioned inside the cylinder and hides and protects an anti-theft bolt positioned inside a hole, which crosses the entire anti-burglary block and has a larger diameter at the front and the same diameter as the anti-theft bolt in the back, so as to receive the anti-theft bolt in a threaded spot in the inner wall of the cylinder and enable placement of the anti-theft bolt in the body of the anti-burglary block when totally tightened into the threaded spot, wherein the end of the anti-theft bolt, in closed position, is housed in a locking hole on a circular support of the cover.

Underground utility enclosure cover assemblies are used with direct burial enclosures. The cover assemblies include a frame and a cover. The frame has one or more walls that define a central opening, a cover receiving ledge, an overhang that has a sidewall, and at least one stabilizing member extending from a bottom edge of the sidewall of the overhang. The cover is dimensioned to rest on the cover receiving ledge. The frame and the cover are made of a rigid material that permits the frame and cover to support large vertical loads.

Enclosure cover assemblies for use with direct burial enclosures are provided. The enclosure cover assembly includes a frame that is secured to the enclosure and a cover separately secured to the frame. The frame and cover are made of metal while the enclosure is made of a high strength material.

Ways of marking an open construction hole may include using a marker device for marking an open construction hole. The marker device may include a planar body including a top side and a bottom side and a post disposed on the bottom side of the body. The post may be placed in the open construction hole to stabilize the marker device when the marker device is marking the open construction hole. A marker may be removably coupled on the top side of the planar body opposite the post. The marker may include an elongate body that extends in a direction away from the planar body when the marker may be coupled to the top side of the planar body.
