Benefits of technology

"The present invention provides a temporary ramp for use on roadways under construction, which includes elastomeric ramp segments that can be easily assembled and disassembled by a single operator. The ramp segments can be detached from each other for easy handling, and they are re-usable to save materials. The ramp segments can also have a core of rigid material to resist shifting caused by vehicles traveling over the ramp. Hinge mechanisms can be positioned between adjacent ramp segments for easy transportation, and fasteners can be used to secure the ramp segments to the roadway. The technical effects of this invention include improved efficiency and ease of use, reduced material waste, and improved stability of the temporary ramp."

Problems solved by technology

The roadways have elevated obstructions such as manholes located in the roadway.

Embodiment Construction

[0024] Referring now to FIGS. 1-11, there is shown the preferred embodiment of the present invention. FIGS. 1-3 show a round manhole structure 10 which extends upwardly above the top surface of a roadway 12. The roadway 12 as shown is under construction, and the top layer of roadway has not yet been installed. Therefore the manhole structure 10 temporarily extends above the elevation of the roadway surface 12. The manhole structure 10 creates an obstruction to vehicles traveling the roadway. A temporary ramp 14 according to the present invention is provided for allowing vehicular traffic to smoothly and easily ride up and over the circular manhole structure 10. The temporary ramp 14 shown in FIG. 1 includes four ramp segments 16 that can be fitted together to form a single ramp structure 14 around the manhole 10. The ramp segments 16 are made of a material such as plastic, rubber, or high strength composite material.

[0025] Each ramp segment 16 shown in FIGS. 1-3 includes edge porti...

Abstract

A temporary ramp having a plurality of segments coupled together by way of interlocking mating shapes located along the edges of adjacent ramp segments. Hinges couple adjacent ramp segments together. Fastener openings defined in the ramp segments allow a fastener to be fixed with the underlying roadway to help secure the ramp segment in position.

Description

BACKGROUND OF THE INVENTION [0001] This invention relates to temporary ramps for use on roadways under construction, wherein the roadways have obstructions such as manhole structures which are temporarily positioned at slightly higher elevations than the existing roadway. [0002] During roadway construction, various structures such as manholes, storm sewer inlets and structures which allow access to water mains are constructed at a raised elevation corresponding to that of the finished roadway. The roadway is then built up such that the surface of the roadway is at the same elevation as the manholes, storm sewers and other structures, resulting in a smooth roadway with all structures being at the proper elevation. [0003] Other roadway construction projects involve removing the top layer of roadway by grinding and then replacing it with a new surface layer. Removal of the top layer of these roadways leaves the structures such as manholes and sewer inlets slightly elevated. These eleva...
