is shown a typical excavation site 205 with an excavation hole 206 incorporating corner connections 211 u2013 214 for temporary shoring 218 according to a preferred embodiment of the invention the temporary shoring 218 actually comprises three major elements interlocking sheet piling 219 reinforcing i beams or shoring beams 220 u2013 223 and corner connections 211 u2013 214 each connection including two connectors for the i beams 220 u2013 223 although shown here as i beams beams of different shapes could be used so long as the connector and beam have mating shapes for example round l shaped and u shaped beams could be used as could a beam of almost any cross section interlocking sheet piling 219 is shown placed along the walls of the excavation hole 206 such interlocking sheet piling 219 which in the embodiment shown is formed by interconnecting two types of side wall panels and corner panels not separately labeled is usually driven into the ground prior to any digging typically a driving machine 225 which is essentially a pile driver is used to drive each section of piling 219 to a desired depth within the ground as mentioned above typically such sheet piling 219 was driven two to three times the depth of the excavated hole 206 in this preferred embodiment however because of the i beams 220 u2013 223 and the corner connections 211 u2013 214 the sheet piling 219 need only be driven slightly deeper than the desired depth of.
