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.

Provided are various examples of a temporary manhole cover and its methods of use configured to prevent an entire person from falling into a manhole, while providing a unique structure, adjustable in some embodiments, that allows access for a user to simultaneously reach through and/or pass objects through the temporary manhole cover when it is installed in a manhole. The structure may include an annular perimeter portion optionally having an L-shaped cross-section defining a circular interior opening there-through, a first set of two parallel laterally-separated cross-members each attached with and extending across the circular opening, and a second set of two parallel laterally-separated cross-members each extending perpendicularly between and attached with the first set of two parallel laterally-separated cross-members.

A wall trench panel and system utilizes extruded aluminum panels having ribs and a socket edge and a ball edge which allows them to slide together and create a continuous trench wall that may be stabilized using traditional jack and wale techniques. To allow the trench to make a corner, a knuckle is provided which accepts both ball and socket edges of the panels to change the direction of the panels. In deep trench situations, panels of different sizes are provide to stager the installation of the panels which provides a continuous trench wall that is very strong and stable which eliminates the necessity of staging the trench in ever smaller portions.

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.

A swimming pool assembly, including a swimming pool body defining a pool top edge and an oppositely disposed bottom pool floor member connected by at least one pool wall and having a shallow deck portion and a support structure for providing support to the deck portion operationally connected to the deck portion and extending away from the pool top edge. The support structure further includes a support structure floor member, at least one support structure wall member extending therefrom and connected to the shallow deck portion to define an enclosure, and at least one fluid access aperture formed through the support structure wall member to provide fluidic communication with the enclosure.

A locking cover apparatus for construction vaults. The cover has a latch portion configured to rotate in a first and second direction when a threaded locking security bolt is rotated in the first and second direction respectively, and where the cover is locked from removal from the vault when the latch portion comes into contact with a first stop mechanism after rotating in the first direction and wherein the cover is unlocked when the latch portion comes into contact with a second stop mechanism after rotating in the second direction.
摘要:
A protective housing (12) is provided for a sheet pile (10) and has a length extending beyond the upper end (10A) and lower end (10B) of the sheet pile (10). A separate force transmitting member (26) is mounted on the protective housing (12) and has a horizontal plate (28) engaging the upper end (10A) of the sheet pile (10) for driving the sheet pile (10) downwardly upon exertion of a downward force from a suitable power source (44) to force the protective housing (12) downwardly. To separate protective housing (12) from sheet pile (10) upon driving of the sheet pile (10) to a desired predetermined depth so that protective housing (12) may be withdrawn, a fluid pressure device (50) is mounted between protective housing (12) and the force transmitting member (26). Upon actuation of fluid pressure device (50), protective housing (12) is moved upwardly while sheet pile (10) remains in position thereby to initially break loose the protective housing (12). After the initial separation of protective housing (12) the protective housing (12) along with the force transmitting member (26) may be lifted upwardly for removal by a suitable overhead lift means such as a crane.
