3. INTRODUCTION
A. GENERAL
 DEFINATION OFTUNNEL:-
TUNNELS ARE UNDERGROUND ARTIFICIAL
PASSAGES OR ROADWAYS USED FOR
TRANSPORTATION.THEY COULD BE USED FOR
CARRYING WATER,SEWAGE,GASES,PASSENGERS
ETC.THE METHODS INVOLVE ARE
UNDERGROUND OPERATIONS KNOWN AS
TUNNEL DRIVING ANDTHE GROUND SURFACE IS
NOT DISTURBED.

4. B. NEED OF THE PROJECT
THE EXISTING PIPELINES IN MUMBAI ARE 110
YRS. OLD ANDTHEY ARE ABOVETHE EARTH
SURFACE SOTHEREWERE CORROSION AND
SAFETY ISSUES DUETO SALTYWATER AND HIGH
HUMIDITY ALSO EXPECTED POPULATION OF
MUMBAITILL 2021WILL BE 163.5 LACS AND 2051
WILL BE AROUND 200.43 LACS SOTHEREWILL BE
NEED OF MORE WATER SUPPLIES SO WATER
PIPELINES ARE NEEDED FOR FULFILLING
FUTURE DEMANDS. FOR MEETING ALLTHESE
PROBLEMS UNDERGROUND WATER SUPPLY
TUNNEL IS CONSTRUCTED.

5. C. OBJECTIVES OF THE PROJECT
SOTO FULFILLTHEWATER SUPPLY DEMAND
IN SAFE AND UNINTERRUPTED MANNER IN
FUTUREA MAJOR PROGRAMWILL SOON GET
STARTED BY BMC.

6. 2. SALIENT FEATURES OF THE
PROJECT
 CONSTRUCTION OFVERTICAL SHAFTWITHINTHE
WELL OF FINISHED DIA AND DEPTH OF SHAFT
FROMTHE GROUND LEVELWITHTHE HELP OF
CONTROLLED BLASTINGAND CONVENTIONAL
DRILLING.
 EXCAVATIONOFTAILTUNNEL AND ASSEMBLY
TUNNEL BY CONTROLLED BLASTINGAND
CONVENTIONAL DRILLING.
 BORING OFTUNNEL BY MODERN FULL FACETBM
INCLUDING
COMMUNICATION,FACILITIES,LIGHTINING,VENTILA
TION,DEWATERING ETC.

7. 3. SCOPE OF THE PROJECT
 SURVEYING FOR FIXING LOCATION OF
SHAFTAND ALIGMENT OFTUNNEL
BETWEENTHE SHAFT.
 CONSTRUCTION OFVERTICAL SHAFT BY
CONVENTIONAL DRILLING AND
CONTROLLED BLASTING METHOD
 PROVIDE CONCRETE REINFORCEMENTTO
THE PIPES SHAFT,ANCHOR BOLTS ETC.

8. 4. LIST OF MATERIALS
 CEMENT
 AGGREGATES
 ADMIXTURES
 REINFORCEMENT
 INSULATION MATERIALS FORTUNNEL
AGAINSTWATER
 ANTI BACTERIAL PAINT

9. 5. CONSTRUCTION METHODOLOGY
 A.WELL SINKING
THEWELL FOUNDATIONGENERALLY
CONSIST OF CONSTRUCTION OFTHEWELLS
AND SINKINGTHEM DOWNTOTHE REQUIRE
LEVEL BY DREDGING OFTHE SOIL AND
OTHER MATERIAL,PLUGGINGTHE BOTTOM.
DEWATERING INSIDETHEWELL AND
GROUTINGTHE ROCK ATTHE JUNCTION OF
THEWELL ANDTHE ROCKTO CONTROL
LEAKAGEOFWATER.

10.  B. SHAFT CONSTRUCTION
DETAILED SURVEY IS CARRIED OUTTO
ESTABLISHTHE LENGTHAND BEARING OF
TUNNEL BETWEENTWO SHAFT.
AFTER SINKING OFWELL,THE SHAFT ISTO
CONSTRUCTWITH CONTROL BLASTING.FORTHE
CONTROLLED BLASTING OF SHAFT,THE
DRILLING PATTERN IS MADE.
GEOLOGICAL INSPECTION IS CARRYING OUTAT
VARIOUS LOCATION DURINGTHEWORK.
IFTHE ROCK ISWEAK,POOR IT IS SUPPORTED
SUITABLY BY PROVIDING LAGGINGAND BACK
FILLINGWITH CONCRETE (M25 GRADE).

11.  C.TUNNEL CONSTRUCTION
THETUNNEL IS EXCAVATED USING 6.25 M DIA
MODERN FULL FACETBM INCLUDING
COMMUNICATION FACILITIES,LIGHTINING,SAFETY
MEASURES ETC.
FOR LINING OFTHETUNNELTHE CONCRETE USED
IS OF GRADE M25 OF REQUIRED SLUMP OF 90-120
MM
