GEO-TECH CONDITIONS AND SOLUTIONS

• Malaysia: – Very Poor Soil Conditions.

• Peat, Marine Clay, Organic Soils or Lime Stone Cavities • Geo-tech solutions aim at ZERO Formation settlement despite poor

Soil Conditions • Ground Improvement Cost May be as much as 20% of the Infra

Project Cost

– Stone Columns – RE walls used in Rly. Bridge Approaches! – Soli Nails and Crib Walls are very common in Cutting – Geotextile sandwitched between sand layers is a standard,

even for Existing Track Rehabilitation • PVD • Geo-wrapping on Temporary Railway Banks • Geo Cells

HIGH FORMATION / CUTTINGS

• HIGH EMBANKMENT IN COUNTRY SIDE

• HIGH CUTTING • 3mt BERM EVERY 6mt HEIGHT

• BERM DRAIN, CASCADING DRAIN, TOE SIDE DRAIN

• RAIL HANDLING CRANE EQUPIED DMT

• STEEL CHEQURED PLATE TROLLEY PATH WAY

MPOB (MOTOR CYCLE/ PEDESTRAIN BRIDGE)

BALLAST BOX FOR BOTTOM BALLST SPREADING

• EVEN 150mm BOTTOM BALLASTING

• LESS MANUAL LABOUR

• BETTER INITIAL TRACK GEOMETRY ON LAYING SLEEPERS WITH SLEEPER LAYING BEAM

16

STONE COLUMNS FOR WEAK SOILS

• FASTER CONSOLIDATION AND STRENGTH MOBILIZATION: – PROVIDES A DRAINAGE PATH THROUGH ORGANIC PEAT /

MARINE CLAY

– PROVIDES A SUPPORT COLUMN 17

ROB 09 ABUTMENT B MATIER’S ARCH

Longitudinal profile of proposed road

• LENGTH OF MATIER’S ARCH CONSTRUCTED IS 62.5m AT A TOAT COST

OF RM 1.24 MILLION. RATE PER METER OF MATIER’S ARCH IS RM19,840.

• MATIER’S ARCH AT ROB 09 WAS COMPLETED WITHIN THREE MONTHS.
