CBB CHECK BY: WDL SCALE: N/A SPA 1.0 Ground Nail Wall and Micropile Materials 1.1 Ground nails and Micropiles - Grade 75 bare threadbar, R38 or R32 Self Drilled Anchors in accordance with ASTM A615. fy = 75,000 psi 1.2 Grout - Grout may be neat-cement or with sand, with Type 1/11 or I II cement in accordance with ASTM C150. Water-cement ratio should be between 0.4 and 0.6. f c = 3,000 psi minimum 1.3 End hardware - Nuts and washers shall be in accordance with ground nail manufacturer's recommendations. Bearing plate shall be in accordance with ASTM A36, Grade 36. 2.8 Once the grout and shotcrete have attained 50% of their specified strengths, repeat 2.2-2.7 to the bottom of the wall. 3.0 Temporary Shoring Design Parameters 3.1 3.2 1.4 Shotcrete - Shotcrete mix shall consist of Type II cement in accordance with ASTM C150, potablewaterand normal- weight aggregate- in accordance-With ASTM_C33._ Air-,entrainment-is- not required. Admixtures, if used, should be non-corrosive to steel. 3.3 f c = 4,000 psi (28-day strength) 3.4 The ground nail wall has been designed in general accordance with procedures contained in the FWHA "Manual for Design and Construction Monitoring of Soil Nail Walls", Report Number FHWA-SA-96-069R. The following values have been used for the design parameters: c y quit Material Description (deg) (psf) (pcf) (psi) Silty Sand and Cobbles 30 100 125 20 The required allowable force for the ground nails is 1.5 kips/If. The groundwater table was assumed to be below the shoring wall. 2.7 Shotcrete over the ground nail end hardware to attain minimum coverage requirements. Concrete - Concrete mix shall consist of Type II cement in accordance with ASTM C150, W potable water and normal weight aggregate in accordance with ASTM C33. Air entrainment is 3.5 Factors of safety: C0 not required. Admixtures, if used, should be non-corrosive to steel.

PLOT DATE: 5116/07 FHWA-SA-96-069R. 2.2 Excavate one lift. Ground nails may be drilled and installed through a temporary stabilizing 4.3 Proof testing of the ground nails shall be performed on 5% of the nails or as berm if necessary. directed by the shoring design engineer. A passing verification test can be counted towards the proof testing requirement. 2.3 Install ground nails at the approximate locations and to the lengths shown on the plans. Ground nail locations may vary from the specified spacing by up to 6". 4.4 Shoring details may be modified by design Engineer. 2.4 Install welded wire mesh and walers as shown on the drawings. 4.5 This design is valid only for this site and is to be constructed by HTM Construction 2.5 Install shotcrete to cover welded wire mesh and walers. Give special attention to filling the void only. in the borehole above the grout line. Cold weather protection measures may be necessary. 4.6 The ground nail walls may be redesigned based on verification test results. 2.6 Install the ground nail end hardware while the shotcrete is still wet. Embed into the shotcrete surface until there is no void behind the plate. Hand tighten the nut. 2.7 Shotcrete over the ground nail end hardware to attain minimum coverage requirements.
