the pre cast pit in position it is not anticipated that the keyway joint will experience much shear loading since the pre cast pit is resting on the building footings in order to improve the strength of the pre cast pit certain edge surfaces of the pit 10 can include an angle beam 40 thus as shown in fig1 an angle beam can be provided at the top edge 37 of the side walls 12 as well as the top edge top edges of the front wings 30 in addition an angle beam 40 can be provided at the front ledge 28 of the front panel 14 preferably the angle beams are cast into the pre cast pit 10 when the pit is formed alternatively the top edges of the side panels front panel and front ledge can be configured to include a ledge for flush mounting of the angle beams 40 since the pre cast pit 10 is fully formed before it is placed at the building site some means must be provided to allow the pre cast pit to be carried and lowered into position consequently the pre cast pit includes fort lifting rings 42 projecting inward from the front panel 14 and rear lifting rings 44 projecting upward from the rear slab edge 34 as shown best in fig2 and 5 since the lifting rings will be covered by the poured building slab the location and size of the rings can be readily altered it is preferable however that the location of the lifting rings 42 44 allow for balanced lifting and lowering of the pre cast pit one optional feature of the pre cast pit 10 of the present invention is a pre cast electrical access opening 46 through one or.
