WATERPROOFINGDEFINITION

Various types of waterproofing materials are used in modern tunnel construction. Solid waterproofing is made of waterproof building organic or synthetic film filter materials, synthetic resinous materials, and steel sheets.

May be partial as with “umbrella” waterproofing. Example for a tunnel roof , in which case it is not exposed to hydrostatic

pressure.The function to enhance safety and function as well as increase useful life of these structures.protect important structures against corrosion. It reduces maintenance costs and repairs.

The waterproofing of a tunnel consists of -A support - A protective geotextile - A waterproofing fabric membrane

The TSGs, which are located in precast grooves encircling the mating faces of each segment, give a secure rubber-to-rubber waterproof seal as soon as the segments are bolted together

bored tunnel.

The Omega seal allows joint movement in combination with water pressure. Applicationsencompass the connection between a bored tunnel and the entrance to a structure such as a rail station

TYPICAL SUPPORT ELEMENTS

1. STEEL ARCHES( SLIDING SYSTEM) = STEEL LINING SYSTEM

Gantry acts as the working platform to install formwork and move forward gradually as it completed.

i. REINFORCEMENT CONCRETE LINING
