Device and system for excavating and backfilling soil
First Claim
1. A trench edging member comprising:
- a substantially rectangular shaped horizontal section constructed to be placed on a ground surface adjacent a trench to be excavated, said horizontal section including a longitudinal front edge and a pair of side edges,an inclined vertical section joined to said substantially horizontal section forming a back stop for soil as it is thrown onto the trench edging member, said vertical section being substantially rectangular in shape and substantially the same width as said horizontal section, said vertical section including a rear longitudinal edge;
said horizontal and said vertical sections of said trench edging member being formed with a plurality of undulations having peaks separated by valleys, said peaks and valleys spaced for nested engagement with like constructed trench edging members in a stacked arrangement, said undulations include a height, said height of said undulations increasing as they approach the junction between said horizontal section and said vertical section, whereby the buckling strength of said trench edging member is increased.

Abstract
A trench edging member to be placed adjacent a trench or hole in the ground is designed to retain the soil removed from the trench, not destroy the landscape beneath the device, and enable an individual to readily replace the soil back into the trench or hole. A plurality of these devices can be placed adjacent each other so that a long trench can be dug filled with the required equipment or utilities, and the soil replaced back into the trench. The material employed for the device is formed into an undulating or wavy pattern when viewed in cross section. This enables a plurality of the devices to be nested or stacked atop one another for storage and/or transportation. The undulations also add rigidity to the device without adding weight to the device.

11. A trench edging member comprising:
-
a substantially horizontal section constructed to be placed on a ground surface adjacent a trench to be excavated, said horizontal section including a longitudinal front edge and a pair of side edges, an inclined vertical section integrally formed to said substantially horizontal section forming a back stop for soil as it is thrown onto the trench edging member, said vertical section including a rear longitudinal edge, said horizontal and said vertical sections of said trench edging member being formed with a plurality of undulations having peaks separated by valleys, said undulations providing strength against buckling of said trench edging member when loaded with soil, said peaks and valleys spaced for nested engagement with like constructed trench edging members in a stacked arrangement, said undulations including a height, said height of said undulations increasing as they approach the junction between said horizontal section and said vertical section, whereby the buckling strength of said trench edging member is increased. - View Dependent Claims (12, 13, 14)
