A folding, flared utility vault or enclosure that may be used to protect public utility valves, electrical cables, switches, fiber optic cables, or the like is provided. The system generally comprises a base box having a front panel, back panel, and side panels. Alternative embodiments may further comprise an extension box having a front extension panel, back extension panel, and side extension panels. The various panels of the base box and extension box may have flared bottoms that prevent removal after installation. Additionally a user may attach extension boxes to the base box to increase the amount of storage area within the system.

An in-ground enclosure for housing electrical components is provided. The in-ground enclosure can include an outer shell defining an internal compartment housing a lift system, an equipment rack structure connected to the lift system, an upper panel comprising a compartment opening for accessing the internal compartment, an enclosure cover adapted to cover the compartment opening and for removably sealing the compartment opening. In certain uses, a telecommunications base station may also be provided. The telecommunications base station can include the in-ground enclosure and a cellular base station, with the cellular base station including an antenna coupled to signal processing equipment and a power supply.

A foldable rectangular plastic/composite enclosure having first, second, third and fourth sides connected by hinges. The enclosure folds flat by rotating the sides on the hinges but is constructed to fold only in one direction. The hinges allow the enclosure to be folded flat for storage and transportation. The hinges are composed of a plurality of hinge members wherein each hinge member is positioned in a housing. The housing has an open interior which helps anchor the enclosure in the ground. An insertable locking pin can be inserted through each hinge to prevent the enclosure from folding. The enclosure can be made of plastic/composite imbedded with fibers such as carbon fibers, glass fibers, or ceramic fibers or imbedded with particles such as glass particles. The use of plastic/composite and various openings or cutouts makes the enclosure light weight.

A flow restrictor for installation in a connection having a terminus opening into an underground vault. The flow restrictor includes an annular restriction device and a concentration member. The annular restriction device is configured to be installed in the annulus near the terminus opening and to restrict a flow of one or more gases through the annulus of the connection. The concentration member is configured to concentrate the flow and includes a through-channel configured to allow the concentrated flow to flow between the underground vault and the annulus.

This installation has at least one electric cable (12) having three conductors. At least one cable duct contains at least one section of the cable (12) and at least one connection chamber (10) in which two sections of the cable (12) are connected by means of a connection joint (14). The cable (12) is a helical assembly of the three conductors which comprises neither armouring nor sheath around this assembly.

Multipurpose tactile warning panels for use in pedestrian walkways, and in particular tactile warning panels that are designed and built with multifunction/multipurpose capabilities that serve the visually impaired and enable the deployment of smart city technology by integrating tactile warning systems and subsurface enclosures that can withstand pressures of five (5) tons up to and exceeding sixty (60) tons and incorporate small cells, beacons, sensors, Fog Computing, electric energy generation, rechargeable power supplies, wireless M2M communication and a plethora of other smart city technologies.

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.
