Q1. What should be the height of Tremie pipe from pile founding level during concrete?
Ans. 
The height of Tremie pipe from pile founding level during concrete should be maintained at a certain level to ensure proper placement of concrete.
• The Tremie pipe should typically be kept at a height of 1-2 meters above the pile founding level to prevent segregation of concrete.

• Maintaining the correct height ensures that the concrete flows smoothly through the pipe and fills the pile without any gaps or voids.

• Adjustment...read more

Q3. What is the role of bearings in Bridges?
Ans. 
Bearings in bridges help distribute loads and allow for movement due to temperature changes and seismic activity.
• Bearings help distribute the loads from the bridge deck to the substructure, reducing stress on the bridge components.

• Bearings allow for movement of the bridge deck due to temperature changes, seismic activity, and other factors.

• Different types of bearings include elastomeric bearings, pot bearings, and slid...read more

Q4. Which formula is used to calculate the elongation of PSC Girder?
Ans. 
The formula used to calculate the elongation of PSC Girder is based on the modulus of elasticity and the change in length.
• The formula for calculating elongation is: Elongation = (Load x Length) / (Modulus of Elasticity x Area)

• Modulus of Elasticity is a measure of a material's stiffness and is specific to the material used in the PSC Girder

• The change in length is the difference between the original length and the length...read more

Q5. What is the Process of Making PSC Girder?
Ans. 
The process of making PSC girder involves preparing the concrete mix, casting the girder in a formwork, curing, and testing for quality.
• Prepare the concrete mix with a specific ratio of cement, aggregates, and water.

• Pour the mix into a formwork that is designed to the shape and size of the girder.

• Place prestressed steel strands or bars in the formwork before pouring the concrete to provide strength.

• Cure the girder by m...read more

Q6. What is socketing length in Pile?
Ans. 
Socketing length in pile refers to the length of the pile that is embedded into the rock or hard strata to provide additional support and stability.
• Socketing length is determined based on the strength and stability of the rock or strata at the pile tip.

• It helps in transferring the load from the pile to the rock or hard strata, increasing the overall capacity of the pile.

• Socketing length can vary depending on the site c...read more
