A valve box lock for preventing unauthorized access to a shut off valve including a security bolt extending through a hole in a valve box cover and received into a threaded hole in a cam piece mounted to the undersurface of the cover, the cam piece is moved up and down by rotation of the security bolt in either direction. The cam piece engages a pair of locking plates which are moved radially out into engagement with an inner surface of the valve box to prevent removal of the cover when the security bolt is rotated in one direction, or are retracted radially to release the cover so as to be able to be removed. A automatic lubricating arrangement is associated with the security bolt to insure that it is able to be turned by excluding any.

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.

A portable securing apparatus which is readily secured to a manway of a vessel having a portal intended to enable entry of service personnel into the vessel is described. The securing apparatus affords an improved grip to assist service personnel to enter the vessel. The securing apparatus is for temporary mounting to the manway. The securing apparatus includes a mounting plate mountable to a flange conventionally provided as part of the manway, and a handle for accommodating manual grasp of the securing apparatus.

A lid for a utilities vault having a moldable core and a reinforcement matrix positioned within the core, the reinforcement matrix including longitudinally and laterally extending intersecting members and a plurality of lid feature housings positioned on and attached to the intersecting members, the lid feature housings extending through the core and protruding to the upper and lower surfaces of the lid, and the plurality of longitudinally and laterally extending intersecting members have a height sufficient to provide reinforcement without a perimeter member for the reinforcement matrix.

A temporary manhole cover includes a hinge to permit a portion of the cover to be pivoted open and closed. And a roller for use with a hose or rope facilitates cleaning and inspection of the manhole.

A system for monitoring a structures containing utility components is provided. The system includes a sensing devices, each being disposed within a structure and distributed within a geographic region, each of the sensing devices measuring parameters within the structure. A display is coupled to the sensing devices and is positioned remotely therefrom. One or more processors communicate with the sensing devices and the display. Wherein the processors perform a method comprising: receiving the measured parameters; comparing the measured parameters to thresholds; displaying on the display device elements, each device element representing one of the sensing devices, each of the device elements being geometrically arranged on the geographic distribution of the sensing devices; displaying on the display a plurality of elements, each associated with one of the device elements; and changing at least one of the elements when a measured parameter crossing one of the thresholds.

A subgrade vault system with a locking lid assembly is provided. Specifically, a subgrade vault suitable for housing utility and similar equipment is provided, the vault comprising a main body portion, a cap, and a lid that may be selectively secured with one or more rotatable locking mechanisms to prevent or deter unauthorized access to vault contents.

A cap assembly can include a cap holder device with a plug member and a cap holder. The cap holder device is positionable in an end of a conduit positioned along a roadway. The cap holder is carried by the plug member and includes a magnetic element and a connector. The connector is connectable to the magnetic element to the plug member such that the magnetic element is movable relative to the plug member so as to position the magnetic element for releasably holding a cap that covers the end of the conduit when the plug member is positioned in the conduit. The cap assembly can be a debris cap insertable in a conduit, an end of a pipe, or other opening.
