B.L. Kashyap & Sons DGM-Projects Interview Questions and Answers

Cable (stress) is provided in bridge to increase its load carrying capacity and improve its stability.

• Cable (stress) helps to distribute the load of the bridge evenly.

• It reduces the amount of material required for construction.

• It also helps to improve the stability of the bridge.

• Cable (stress) is commonly used in suspension bridges.

• It allows for longer spans to be constructed without the need for additional support.

• Cab...read more

The hydraulic gradient line is a line representing the total head of water at various points along a flow path in a hydraulic system.

• It is a graphical representation of the total head of water in a hydraulic system.

• It shows the energy level of water at different points along a flow path.

• The slope of the hydraulic gradient line indicates the direction and rate of flow of water.

• It is used in analyzing flow patterns and d...read more

Methods for managing floods include structural measures, non-structural measures, and preparedness planning.

• Structural measures include building dams, levees, and flood walls to control water flow.

• Non-structural measures involve land-use planning, zoning regulations, and wetland preservation to reduce flood risk.

• Preparedness planning includes early warning systems, evacuation plans, and community education on flood saf...read more

Prestressed concrete is a type of concrete that has been compressed prior to being subjected to loads.

• Prestressed concrete is created by introducing internal stresses in the concrete before it is subjected to external loads.

• This compression helps to counteract the tensile stresses that the concrete will experience during use.

• Prestressed concrete is commonly used in bridges, parking structures, and high-rise buildings.

• E...read more

A flood wall is a structure designed to prevent flooding by holding back water.

• Flood walls are typically made of concrete, steel, or other strong materials.

• They are commonly used along rivers, coastlines, and other areas prone to flooding.

• Flood walls can vary in height and design depending on the level of protection needed.

• Examples of flood walls include the Thames Barrier in London and the flood walls along the Missis

The hydrotest pressure is 1.5 times the design pressure.

• Hydrotest pressure is the pressure applied to a vessel or pipeline to check for leaks or defects.

• It is usually done before commissioning the system.

• For example, if the design pressure is 100 psi, the hydrotest pressure would be 150 psi.

The procedure for fit up inspection includes classification, cleaning, alignment, root gap, root face, bevel angle, and mismatch or overlap.

• Classify the base metal

• Clean the surface

• Align the parts to be joined

• Check the root gap and root face

• Measure the bevel angle

• Check for any mismatch or overlap

• Ensure all specifications are met
