| DewateringDewatering | To setup a cofferdam dewatering system, including boring, pump installation and outflow pipework and drainage tanks etc, typical rates are...Small 2 hole system, for an overrun tunnel, with a single drilling rig takes about 7 - 10 days to get up and running.A larger system, with 10 - 15 holes, for a station type cofferdam will take in the region of 3 weeks with 2 rigs. This can be speeded up with the use of more rigs to reduce the well boring times.A typical rate of 2.5 days per pump installation can be used to calculate detailed pumping arrangements. The water level can be dropped in a "closed cofferdam" within a 6 to 8 hour period for a 25,000 m2 cofferdam with a 2 m water level reduction. For smaller closed areas it will take only a few hours at most to reduce the water level by 2.5 - 3 metres.Recharge System - Average well depth of say 55 m deep, not into rock, 9 wells in 10 days or 1.11 days/no with an additional 4 - 5 days to connect pipework and recharge backup tanks etc.DewateringTask / DescriptionSlow Ave Fast Units Setup small 2 hole system10.0 8.0 6.0 days Setup large 15 hole system- 21.0 - days Calculate system times per pump- 2.5 - days/pump Setup Recharge System- 3.5 - days/pump | Dewatering |

| Spoil By BargeExcavation Works | Removal / Transportation Of Spoil By Barge: The size, getting material to the facility, location and movement restrictions of the barge loading facilities are critical to production. A 2,000 m3 flat bottom barge, could easily be loaded 1.5 times per day, with a planned allowance of 2 no movements per day for example... 1,000 m3 barge, filled in 9.5 hrs = 2 movements/day 1,500 m3 barge, filled in 6.5 hrs = 3.5 movements/day | Spoil By Barge |
| Spoil By ConveyorExcavation Works | Removal / Transportation Of Spoil By Conveyor: The size and location of the conveyor are critical to production and should be sized according to the most critical peaks in excavation. There are the following parameters to select... Max excavation per hour 185 m3/hr Assume belt size 600 mm Assume conveyor trough angle 20 degrees From the above you read off specific parameters from the suppliers table... Recommended belt speed 150 m/min Angle of repose for dry sand 35 degrees Angle of surcharge 20 degrees You must then read off, from the manufacturers tables the conveyor capacity... Cross-sectional area of load 0.02979 m2 At a speed of 150 m/min gives 268 m3/hr Assume a bulking factor for excavated sane = 15%, and assume 50 minutes work per hour to allow for blockages and maintenance etc... 268 x 85% x 50/60 = 190 so therefore capacity of conveyor = 190 m3 per hour = OK.
