Tunnel lining is the process of constructing a protective layer inside a tunnel to provide stability and prevent water ingress.
Tunnel lining can be done using various methods such as shotcrete, precast concrete segments, and cast-in-place concrete.
Shotcrete involves spraying a mixture of cement, sand, and water onto the tunnel walls using a high-pressure hose.
Precast concrete segments are manufactured off-site and then...
Gantry lining is a construction technique used to reinforce and stabilize tunnels or underground structures.
Gantry lining involves the installation of precast concrete segments or steel plates along the tunnel walls.
These segments or plates are carefully positioned and secured to form a continuous lining.
The lining provides structural support, prevents soil or water ingress, and enhances the overall stability of the tu...
Vibrators are used in gantries for compacting concrete and ensuring its strength and durability.
Vibrators are used to remove air bubbles and excess water from freshly poured concrete.
They help in achieving proper compaction and density of the concrete.
Vibrators are commonly used in the construction of bridges, dams, and other large structures.
They can be handheld or attached to the gantry for larger-scale operations.
Ex...
The density of concrete is a measure of its mass per unit volume.
Density of concrete typically ranges from 2200 to 2500 kg/m³.
The density can vary depending on the composition and aggregates used.
Lightweight concrete has lower density, around 1600 to 2000 kg/m³.
High-density concrete, used for radiation shielding, can have density up to 6000 kg/m³.

A beam is a structural element that is designed to resist loads applied perpendicular to its longitudinal axis.
Beams are commonly used in construction to support loads over a span.
They can be made of various materials such as wood, steel, or concrete.
Beams can be classified based on their shape, such as I-beams, H-beams, or T-beams.
The design of a beam takes into account factors like span length, load requirements, and
King post and queen post are both types of trusses used in construction, with king post being a simpler design and queen post being a more complex design.
King post is a simple vertical member in a truss, while queen post is a pair of vertical members connected by a horizontal member.
Queen post trusses are stronger and can span longer distances compared to king post trusses.
King post trusses are commonly used in small s...

Tension is a force that pulls or stretches an object.
Tension is a type of mechanical stress that occurs when an object is pulled or stretched.
It is a force that acts in the opposite direction of compression.
Tension is commonly seen in structures like bridges and cables.
Examples of tension include a rope being pulled taut or a rubber band being stretched.
Compression is the action of applying pressure to reduce the size or volume of an object or material.
Compression is a force that squeezes or presses an object or material together.
It is commonly used in civil engineering to test the strength of materials like concrete or soil.
Compression can cause materials to deform or break if the force applied is too great.
Examples of compression include the weight of a building pre...

Lap length and development length for hoop, grade of concrete, and HDPE pipe are specified in code.
Lap length for hoop reinforcement is specified in IS 456:2000 and varies based on the diameter of the bar and the grade of concrete.
Development length is the length of the bar required to transfer the stress from the bar to the surrounding concrete and is also specified in IS 456:2000.
The grade of concrete determines the ...
