A water-tight or air-tight accessible compartment has a removable hatch sealed at the edge with elastically conformable opposing seals, with elongate communication elements extending into the compartment between the opposing seals, seals conforming to the topology formed between the compartment edge and the elongate communication elements.

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.

An apparatus for filling a discontinuity in a roadway associated with a manhole cover. The apparatus includes a manhole anchor, a road pad, and an attachment mean. The apparatus is useful for filling a discontinuity in a roadway associated with a manhole cover and for preventing traffic from swerving to avoid the discontinuity.

A water-tight or air-tight accessible compartment has a removable hatch sealed at the edge with elastically conformable opposing seals, with elongate communication elements extending into the compartment between the opposing seals, seals conforming to the topology formed between the compartment edge and the elongate communication elements.

An assembly of covers for a roadway device has a first cover having a first linking side and a first plate-that extends along a first plane of a plate and which includes an upper surface, and second cover having a second linking side that is adjacent to the first linking side and a second plate that extends along a second plane of a plate and which includes an upper surface, wherein the assembly of the covers includes the linking part that connect the first cover to the second cover along the first and second linking sides; wherein the linking part include the hinge that define an axis of a hinging between the first cover and the second cover along the first and second linking sides. The assembly of covers is applicable to access manholes for accessing telecommunications installations or facilities.

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.

A street cabinet arrangement may include a box portion configured to house contents of a communications network therein and a base portion configured to be disposed underground and having a portion that is configured to support the box portion. The base portion may include a projection base portion configured to extend from the main base portion. At least a portion of the main base portion may be configured to be disposed underground beneath a footpath with a longitudinal dimension of the main base portion and a longitudinal dimension of the projection base portion extending parallel to one another and to the footpath such that at least a portion of the projection base portion is disposed outside of the footpath and configured to support the box portion outside of the footpath with an access portion of the box portion configured to extend parallel to the footpath and facing the footpath so as to provide enhanced access to contents of the box portion from the footpath without obstructing the footpath with the box portion.

The invention relates to a support structure of a cover of a structure capable of being inserted into the ground, for example of a shaft or a channel, wherein the cover (10) comprises a traversable surface (11) and the support structure (20) extends downwards under said cover into the structure and comprises beam-shaped supports (21-23) such that their under support side (24) facing away from the surface (11) experiences a tensile stress when the surface (11) is loaded. The invention is further characterized in that between two areas (A, A) a thickness (D) of the carriers with minimum tensile stress is configured substantially symmetrically in an increasing manner up to a maximum value and then, in turn, in a decreasing manner to form a ball shape when viewing the cover from below.

A water-tight or air-tight accessible compartment has a removable hatch sealed at the edge with elastically conformable opposing seals, with elongate communication elements extending into the compartment between the opposing seals, seals conforming to the topology formed between the compartment edge and the elongate communication elements.

Support structures for electrohydraulic apparatuses in particular of electrical and hydraulic apparatuses of irrigation systems are disclosed. The support structure is configured to be applied to a buriable well for housing and protecting such electrohydraulic apparatuses. On predetermined portions of the support structure a plurality of holes are formed, and are adapted for receiving a corresponding plurality of support means configured to hold, preferably in a releasable manner, one or more electrohydraulic apparatuses. Also described is a buriable well for housing and protecting electrohydraulic apparatuses comprising at least one such support structure of electrohydraulic apparatuses.
