625 Cypress Avenue <br />Geotechnical Investigation <br /> <br />Project No. W1895-88-01 - 28 - April 23, 2024 <br />the existing adjacent foundation, the shoring may be removed, and the new foundation <br />constructed. See illustration below. <br />Saw-cut Slab <br />& <br />Excavate <br />Place <br />Hydraulic <br />Shoring <br />Complete <br />Excavation <br />Below <br />Foundation <br />Place <br />Concrete <br />Remove Shoring <br />& <br />Construct <br />Foundation <br />1 2 3 <br />4 5 6 <br /> <br /> <br />7.11.3 It is recommended that an equivalent fluid pressure based on the table below be utilized for <br />design of hydraulic shoring. <br /> <br />HEIGHT OF SHORED <br />EXCAVATION <br />(FEET) <br />EQUIVALENT FLUID PRESSURE <br />(Pounds Per Cubic Foot) <br />(ACTIVE PRESSURE) <br />EQUIVALENT FLUID PRESSURE <br />(Pounds Per Cubic Foot) <br />(AT-REST PRESSURE) <br />Up to 7 25 67 <br /> <br />7.11.4 It is very important to note that active pressures can only be achieved when movement in <br />the soil (earth wall) occurs. If movement in the soil is not acceptable, such as adjacent to an <br />existing structure, the at-rest pressure should be considered for design purposes. <br />
