Cara Mudah Menentukan Kebutuhan Urugan Tanah dan Jumlah Damp Truck

Summary

This video tutorial explains how to calculate the volume of soil needed for a construction project, focusing on land leveling or excavation. Using a practical example of a 30m x 13m plot, the presenter walks through the steps of calculating the area, volume, and required truckloads. Key concepts such as soil compaction coefficients and truck capacities (4m³ and 7m³) are addressed. The video emphasizes that the process is straightforward, even for beginners, and provides a clear, step-by-step guide to understanding earthworks calculations for civil engineering projects.

Takeaways

• 😀 The video discusses a simple method for calculating earthwork fill requirements, specifically for determining how much soil is needed for a construction project.
• 😀 The example provided involves a land area of 30 meters by 13 meters, with a filling height of 70 cm (0.7 meters).
• 😀 The first step in the calculation is to find the area of the land (30m x 13m = 390 m²).
• 😀 After finding the area, the next step is to calculate the volume of earth that needs to be filled, which is the area multiplied by the height of the fill (390 m² x 0.7m = 273 m³).
• 😀 A coefficient for soil compaction is applied to adjust for the fact that the earth will settle, typically using values like 1.2 or 1.3.
• 😀 After applying the compaction coefficient, the total volume of earth required increases to about 327.6 m³ (273 m³ x 1.2).
• 😀 The calculation then proceeds to determine how many dump trucks are needed to transport the required volume of soil.
• 😀 Assuming a dump truck capacity of 4 m³, dividing the total volume (327.6 m³) by the truck capacity results in the need for approximately 82 dump trucks.
• 😀 If the dump trucks are larger, with a 7 m³ capacity, the number of trucks needed reduces to around 47.
• 😀 The video emphasizes that this method is straightforward and can be understood by even non-experts in construction, though accuracy is essential for proper planning and execution.

Q & A

What is the main focus of the video?

The main focus of the video is to explain how to determine the amount of soil needed for land filling or earthworks in a construction project.

What is the first example discussed in the video?

The first example discusses a land area of 30 meters by 13 meters, where soil excavation is planned to a depth of 70 centimeters.

How is the area of the land calculated?

The area is calculated by multiplying the length (30 meters) by the width (13 meters), which gives an area of 390 square meters.

What is the height of the excavation in the example?

The excavation height in the example is 70 centimeters, or 0.7 meters.

How is the volume of soil to be excavated determined?

The volume is calculated by multiplying the area (390 m²) by the excavation height (0.7 m), resulting in 273 cubic meters.

What does the coefficient factor represent in the calculation?

The coefficient factor accounts for soil compaction during the excavation process. In this case, a coefficient of 1.2 is applied to adjust for compaction.

What is the adjusted volume after applying the coefficient?

After applying the coefficient of 1.2, the volume is adjusted to approximately 327.6 cubic meters.

How is the number of dump trucks needed calculated?

The number of dump trucks needed is calculated by dividing the total volume of soil (327.6 cubic meters) by the capacity of a single truck. If the truck capacity is 4 cubic meters, it would require about 82 trucks.

What happens if the truck capacity is 7 cubic meters instead?

If the truck capacity is 7 cubic meters, the number of trucks needed is calculated by dividing the total volume by 7, which results in approximately 47 trucks.

Why does the video stress the simplicity of the calculation process?

The video emphasizes that the calculation process is simple and straightforward, even for someone without technical expertise, as long as basic multiplication and an understanding of soil compaction are applied.
