3. SMART TUNNEL
• The "Storm water Management And Road Tunnel" or "SMART
Tunnel", is a storm drainage and road structure in Kuala Lumpur,
Malaysia, and a major national project in the country.
• The 9.7 km (6.0 mi) tunnel is the longest storm water tunnel in South
East Asia and second longest in Asia. . It is the longest multi-purpose
tunnel in the world
• The main objective of this tunnel is to solve the problem of flash floods
in Kuala Lumpur and also to reduce traffic jams during rush hour.
• There are two components of this tunnel, the storm water tunnel and
motorway tunnel.
4. ROUTE
It begins at Kampung
Berembang lake near
Klang River at Ampang
and ends at Taman Desa
lake near Kerayong River
at Salak South.
5. HISTORY
• In 2001 the Government sought proposals for a solution that would
allow a typical flood of three to six hours’ duration to occur without
flooding the city center. A tunnel that would allow floods to bypass the
center was one way of achieving this, providing it was coupled with
temporary storage facilities to keep flows downstream of Kuala
Lumpur within the capacity of the river channel.
• A group led by Gamuda engaged SSP, a large Malaysian consultant
engineering firm, and Mott MacDonald UK to develop proposals for a
tunnel with holding ponds at upstream and downstream ends of the
tunnel.
• Construction of the tunnel began in 25 November 2003.
7. CONSTRUCTION
• Two Tunnel Boring Machines (TBM) from Germany manufactured by
Herrenknecht were used, including "Tuah" on north side and
"Gemilang" on south side.
• Gusztáv Klados was the senior project manager of the project.
• The motorway sections on the SMART system was officially opened at
3:00PM, 14 May 2007.
• Meanwhile, the storm water sections on the SMART system began
operations at the end of January 2007.
• As of 18 July 2010 the SMART system has prevented seven potentially
disastrous flash floods in the city center.
9. • The first mode, under normal
conditions where there is no
storm, no flood water will be
diverted into the system.
Mode 1:
No storm,
low
rainfall
10. • When the second mode is activated,
flood water is diverted into the
bypass tunnel underneath the
motorway tunnel. The motorway
section is still open to traffic at this
stage
Mode 2:
Moderate
storm
11. • When the third mode is in operation, the
motorway will be closed to all traffic. After
making sure all vehicles have exited the
motorway, automated water-tight gates will
be opened to allow flood waters to pass
through. The motorway will be reopened to
traffic within 48 hours of closure.
Mode 3:
Major
storm
13. Stormwater tunnel
• Construction cost: US$ 514.6 million
• Stormwater tunnel length: 9.7 km (6.0 mi)
• Diameter: 13.2 m (43.3 ft.) (outer diameter)
• Tunneling method: Tunnel Boring Machine (TBM)
• TBM type: Slurry shield
14. Slurry Shield TBM
• Slurry shields are TBM fitted with a
full face cutter head which provides
face support by pressurizing boring
fluid inside the cutter head chamber.
• These machines are most suited for
tunnels through unstable material
subjected to high groundwater pressure
or water inflow that must be stopped by
supporting the face with a boring fluid
subjected to pressure.
15. Motorway tunnel
• Motorway tunnel length: 4 km (2.5 mi)
• Structure type: Double Deck
• Ingress and egress: 1.5 km (0.93 mi) at Jalan Sultan Ismail and Jalan
Imbi
• Length: 1.4 km (0.87 mi) at Jalan Tun Razak
• Links: 1.6 km (0.99 mi) at Kuala Lumpur-Seremban Expressway
Links: City Centre near Kg. Pandan Roundabout KL-Seremban
Expressway near Sungai Besi Airport
16. FEATURES OF SMART TUNNEL
• Longest tunnel in Malaysia.
• 9.7 km (6.03 miles) stormwater by-pass tunnel.
• 4 km (2.49 miles) double-deck motorway within stormwater tunnel.
• The motorway tunnel is suitable for light vehicles only. Motorcycles
and heavy vehicles are not allowed.
• Ingress and egress connections to the motorway tunnel linking the
southern gateway to the city center.
17. FEATURES OF SMART TUNNEL (cont.)
• Holding basin complete with diversion and tunnel intake structures.
• Storage reservoir and a twin-box culvert to release flood discharge.
• State-of-the-art operations control room equipped with the latest
systems in operations management, surveillance and maintenance of
the SMART system.
• Custom-made fire engine units consisting of two modified Toyota
Hiluxes, parked at two different locations for quick access to the tunnel
in case of fire on both carriageways.
