ABSTRACT:
FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT
There is no federally sponsored research and development to which the instant invention relates.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The instant invention relates to that class of devices serving to facilitate drainage of rainwater from highways and roads servicing motor vehicular travel.
2. Related Art
The contemporaneously filed Art Information Statement sets forth art that however does not anticipate the instant invention.
A SUMMARY OF THE INVENTION
1. A Brief Description of the Invention:
The instant invention consists of a pair of elongated three-sided bottom containment trays with triangularly shaped soffet units affixed to lateral walling of each. Each tray has a beveled posterior end, each such end being oppositely inclined so as to facilitate joinder of each tray at each such end of each when the trays are embedded within a roadway with the abovementioned soffet units serving to facilitate anchoring of the trays in place within the bed of the roadway. Each containment tray holds one silt collection tray with all trays being similar in length. Each silt collection tray has a posteriorly positioned grasping plate affixed to it. A nut and bolt combination serves to, via through holes concentrically positioned near anterior ends of and through each of the containment and silt collection trays, lock them swiveably together.
2. Object of the Invention:
Somewhat steeply inclined and especially unpaved roadways are amenable to not infrequent “washout” destruction after having been subjected to prolonged and/or acute but heavy flowings of water from vantage points higher than but in apposition to such roadways. Such destruction of such roadways is moreover not uncommon in the face of upground melting snow and ice during spring seasons. The instant invention serves to minimize such destruction by providing diversionary sluiceways in the direction of and to the lateral earthen borders of such roadways for diversion thereto of such flowing rainwater or water from such melting snow and ice and concomitant loose silt. Moreover, by virtue of the readily removable tray within a tray feature of the invention, a cleaning away of deposited silt so as to render the invention continuously functional is easily accomplished.
Respectfully submitted, in view of the foregoing, the instant invention being not only new and unique is also unquestionably useful.
