A fastener for attaching an identification placard having a post to a lid for a utility vault from a single side of the lid, the fastener includes a body portion for positioning within a hole in the lid, the fastener having tabs for retaining the fastener to the lid and lobes for preventing over insertion of the fastener into the hole in the lid and a bore extending through or partially through the body portion for receipt of and friction retention and/or mechanical interlocking of the post of the identification placard.

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 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 manhole cover for manholes, sewer accesses or drainage channels, including a reinforcing element and a body made of plastic which is connected to the reinforcing element. The reinforcing element may be constructed from intersecting, vertically aligned elements. Corrugations may be formed in the reinforcing element. The reinforcing elements may be arched and may include an outer encircling strip and a central plate, which are each connected to the body made of plastic. The reinforcing element rests on a bearing surface on the manhole, sewer access or drainage channel when the manhole, sewer access or drainage channel is closed by means of the manhole cover. The body made of plastic includes ribs, which extend perpendicularly or at an angle of more than 45 to the surface surrounding the manhole cover, sewer access or drainage channel when the manhole, sewer or drainage channel is closed.

A fiber reinforced polymer material lid or cover for a utility vault made from an unsaturated polyester thermosetting resin matrix, glass fiber reinforcement, an inorganic filler and an ultraviolet inhibitor. The lid or cover has a flat textured upper surface having a plurality of bosses having different heights extending above the upper surface and a bottom surface having an outer perimeter rim with a recessed interior cavity having a number of continuous support ribs extending through the recessed interior cavity from opposite sides of the outer perimeter of the rim to transfer load placed on the lid or cover and minimize deflection under the load to the outer perimeter rim.

The invention relates to a cover for use on public roads, comprising an outer body (2) that houses at least one reinforcement (1). Preferably, said outer body (1) is made of a plastic material, e.g. injected plastic material, and said at least one reinforcement (1) is connected by means of said outer body (2) to form a single piece.

The cover according to the invention is lighter than that conventional covers, given that it is made with less metal and with lighter materials. Moreover, the cover cannot be easily recycled and hence is not at risk of theft.
