Question Paper
Why do volume and density of earth undergo changes during excavation, hauling, placement and compaction?
The undisturbed density of earth on a piece of land was 700 kg/m^3 . The same earth on excavation, hauling, placement and compaction was found to be 800 kg/m^3 . The loose earth was found to be 600 kg/m^3 . Find the percentage Swell and Shrinkage Factor of the soil.
2. Explain how the following factors influence the selection of construction equipment:
Engagement of local labour
Standard equipment
Availability of spare parts
Chances of future use of the equipment
Unit cost of procurement of the equipment
3. A construction equipment costs Rs 5.0 lakh and its useful life is 5 years with the salvage value of 20% of the procurement value. What is the book value of the asset after 4 years and cumulative depreciation amount at the end of its useful life Use straight line method of depreciation.
4. What are scrapers? What are the different types of scrapers available How is the capacity of a scraper determined What are the practical ways of increasing the production of scrapers?
5. What mechanical equipment would you recommend for loading stockpile material into a carrier for transporting? How are they propelled and mounted Describe briefly the mode of working of the equipment you recommend. Is there any type variation of the equipment you recommend? If so, what are they?
6. What is overlap of compacting rollers For a 2-drum roller of 1·2 m width and overlap width of 1/4 drum, find the overlap fraction. If the above roller travelling at 75 m/min with rolling time of 45 min is used for compacting earth layer of 400 mm in 5 numbers of parses, find the quantity of earth compacted.
7. What are the different types of concrete buckets? How would you define mass concrete State the practices to reduce the placement temperature of concrete.
8. How would you estimate the capacity of a refrigeration plant for pre-cooling of concrete Briefly give an account of control of temperature of concrete.
9. What is a concrete batching and mixing plant? How is water measured in a concrete batching and mixing plant?
10. Briefly give the design aspects of the following:
Slide Gate
Radial Gate
Flap Gate
Butterfly Valve
