Dewatering Cofferdam Works Soil Mix Wall Three auger machine drilling and mixing cement into three cores. H-piles dropped into two, then machine moves along by two holes. • An average output was 4 - 5 m/day.

Page 40 of 100

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. Dewatering Task / Description

Spoil By Barge 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 Conveyor 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. Hong Kong Airport Express Station conveyor was capable of 11,500 m3/week.

Bored Piling Pre-Drilling - Site Investigation • Pre-boring will be carried out at each location to ascertain the target founding level. • Rotary rig drilling operations incorporate the use of a steel core that is used when a core sample is required. Another type of boreing is called “Wash Bore” or “Percussive Bore” which simply means that a bore is flushed out and is used when no soil sample is required. Typical rates are... Type of Strata

With a standard rig, working a 12 hour shift, a typical output rate of 66 hrs/hole/rig is possible. • As-Built Information. On Central Reclamation, Contract UA11/91, borehole drilling completed with the following results... 1. 2. 3. 4.

Average depth of 61.15 m, total depth of 428 m Average rock socket depth of 4.65 m The durations ranged from 4 to 8 days Average of 5.85 days, total duration of 41 days.

The Target Founding level • This is defined as the required socket into the bedrock, which is defined as moderately decomposed rock grade III or better with a core recovery greater than 85% (allowable bearing capacity of 5 mPa). The continuity of the founding rock is demonstrated by continuing the pre-bored hole a maximum of 5 metres or 3 times the pile diameter, whichever is the greater. • The cores are logged, stored and photographed and submitted together with proposed founding levels for approval. Setting Out

Before starting excavation at the pile position the following steps are taken:

http://www.planningplanet.com/print/book/export/html/422384

11/3/2014

Page 49 of 100

• Survey and record the existing ground level at the pile position • Setout the pile location from the reference points and in order to monitor the position of the steel casing, control pins are usually established at two orthogonal positions, offset from the centre of the pile. Pile Tolerances • In the case of out of position casings, adjustment can be made to keep the vertical alignment and plan position within the limits of no more than 75 mm off-centre on plan position and not deviating by more than 1:75 from the vertical axis. Pile Excavation / Casings • The shaft of the pile is excavated within a temporary steel casing with an outside diameter of say approximately 200 - 300 mm greater than the pile diameter. The casing is used mainly in areas of unstable ground and are driven using hydraulic casing oscillator attached to a crawler crane or a casing vibrator. • Shaft excavation is carried out using a single or double hammer grab supported by crawler crane. The steel casing toe is kept in front of the excavation level until it is 0.5 metres above the pile cut-of level. The pile shaft is often flooded with bentonite or water and excavation proceeds to the top of the CDG. • Excavation then proceeds by reverse circulation drilling (RCD) using large diameter drilling heads with special rock cutters and flushing by air lift. Bentonite or water levels are always maintained above the ground water level to ensure stability of the shaft. Calculation Of Bored Pile Construction / Excavation Time • Piling times can be reduced by the use of service cranes for reinforcement and concreting activities. • An additional extended shift would often be required for certain piles, as would RCD down-time. • Forecast construction times can be derived by using output rates (hours per item)...
