You are excavating a location for the vault shown below.The top of the walls shown are 1 foot below grade. Allslopes of the excavation are 1 to 3/4 per OSHA regulations(assuming type A soil) to a toe 1 foot outside the base of thewalls. The walls sit on a slab 1 foot in depth. Draw a sketchof the volume to be excavated, break it into components,and calculate the volume. The material from the excavationis to be used in a compacted fill. The front-end loader excavatingthe vault has an output of 200 bank cubic yards ofcommon earth per hour. It loads a fleet of four trucks(capacity 18 loose cubic yards each) that haul the earth to afill where it is compacted with a shrinkage factor of 10%.Each truck has a total cycle time of 15 minutes, assuming itdoes not have to wait in line to be loaded. The earth has aswell factor of 20%. How many hours will it take to excavateand haul the material to the fill?a. What is the production of this system in cubic yards perhour, assuming the trucks carry 35…
Aside from an excavator, provide at least three other earthwork equipment that you are familiar with. Define the purpose for each equipment.
1.Find the volume of excavation by end area method 2. Compute the volume of fill by end area method
An excavation for a square footing is 3.5m deep. The bottom of the excavation is 4 square meters. If the sides have a 0.5:1 slope, use the frustum formula to calculate the volume of excavation in cubic meters.
determine the volume of fill and cut.
Compute for the volume of excavation using end area method.
Why is it sometimes resorted to digging more than one well at the work site when the groundwater level is to be reduced?
Hello! can you pls help me know this as for my understanding in our subject Geology. a).An excavation is to be made for a footing 1.5 m x 1.5 m. However during the excavation you encountered the water table as shown the depth of excavation to be is 2m from the surface but the ground water table is 1m from the surface.How will you be able to pour the concrete mix for the footing if ground water is continuously infiltrating into your excavation and filling up the pit with water. Draw each stage of the excavation up to finishing up the footing with a short explanation for each drawing, include stage of placing formworks and rebar as well as other process to ensure that additional ground water will not mix with your newly poured concrete. How will you make the footing? (the photo attached is just 1m excavation you still have 1m more to excavate) THANK YOU!! I'll give your answer a LIKE for helping me.
A hydraulic excavator with a 2 cubic yard heaped capacity bucket is excavating in common earth. The depth of the excavation is 8 feet. The excavator has a maximum rated digging depth of 16 feet. The excavated material will be positioned so that the swing angle is 75 degrees. The job efficiency is 55 minutes per hour. Find the expected production per hour.
3. Using the geometric method, determine the amount of excavation required for a 24-foot by 50-foot basement. The measurements are from the outside of the foundation walls. The depth of the excavation is 7 feet. The footings extend 1 foot outside of the foundation walls, and a 3-foot space between the footing and the sides of the excavation must be provided to form the footings. The soil is excavated at a 1:1 (horizontal:vertical) slope. Express your answer in cubic yards. 15. Determine the volume of backfill needed for the base-ment in Problem 3. The footing height is 12 inches. Usethe excavation quantities from Problem 3.
Show complete solution and answer in 4 decimal places The areas of the cross-section of an excavation are 3,897.23 sqm, 4,596.01 sqm, and 3, 786.30 sqm. The spacing of each cross-section from each other is 9.80m. a) Find the volume of Excavation by End Area Method. b) Find the Loose Volume of the soil excavated if it has a swell factor of 15.5%. C) A Dump Truck is rented Php 20,000 per day and can make 7 trips in a day. Find the cost of hauling if 5 Dump Trucks with a capacity of 10 cu. m. per trip is used.
