PILE LOAD TEST (3D Animation) | How Pile Load Test is Done at Site? | Engineer-Verse

Summary

The video explains the process of conducting a static pile load test to assess a pile's ability to carry design loads. A pile is driven into the soil, and a test setup with supports and a steel plate is created. A hydraulic jack is used to apply load, and dial gauges measure the pile's settlement over 24 hours. If the settlement exceeds allowable limits, the pile is deemed a failure. This test is essential for determining the pile's load-bearing capacity under static conditions.

Takeaways

• 😀 The static pile load test evaluates the load-bearing capacity of a pile driven into the soil.
• 😀 A test setup involves placing supports on both sides of the pile, with a man G and secondary guarders for stability.
• 😀 A steel plate is placed on top of the pile to transfer loads through the pile instead of the supports.
• 😀 A hydraulic jack is used to apply pressure on the pile during the test, gradually increasing the load.
• 😀 Dial gauges are attached to fixed supports to measure the settlement of the pile as the load is applied.
• 😀 The test duration is typically 24 hours, during which settlement data is continuously recorded.
• 😀 If the pile settlement exceeds the permissible limit, the pile is considered to have failed the test.
• 😀 The static load applied in the test ensures that the pile’s performance can be assessed under realistic conditions.
• 😀 The hydraulic jack's piston is raised to apply increasing pressure, simulating the load a pile would carry.
• 😀 This test is also known as a static pile load test, as opposed to dynamic load tests.
• 😀 The results of the test help determine whether the pile can safely support the intended design load.

Q & A

What is the purpose of a static pile load test?

The purpose of a static pile load test is to determine the load-bearing capacity of a pile by applying a load and measuring its settlement under pressure.

How is the load applied during the static pile load test?

The load is applied through a hydraulic jack placed on top of a steel plate, which transfers the load to the pile. The load is then measured by the dial gauges to assess the pile's settlement.

What is the role of the steel plate in the pile load test?

The steel plate acts as a platform for applying the load to the pile during the test, ensuring that the load is distributed evenly.

What is the function of the hydraulic jack in the test setup?

The hydraulic jack raises the piston to increase the pressure and transfer the load onto the pile. The greater the pressure, the greater the load the pile can carry.

What are dial gauges used for in a static pile load test?

Dial gauges are used to measure the settlement of the pile as the load is applied, providing data on how much the pile shifts or sinks under the pressure.

What indicates a failed pile in a static load test?

A pile is considered to have failed if its settlement exceeds the permissible limit during the test.

How long does the static pile load test typically last?

The static pile load test is usually conducted over a 24-hour period.

What is meant by 'permissible settlement' in a pile load test?

Permissible settlement refers to the maximum allowable amount of movement or sinking that the pile can undergo without being considered structurally compromised or failed.

Why is static loading used in this test?

Static loading is used in this test to simulate the steady, sustained forces that a pile would experience under normal load conditions, helping to evaluate its long-term performance.

What is the significance of using fixed supports on both sides of the pile?

Fixed supports are used to stabilize the pile during the test, ensuring that the applied load is accurately measured and that the pile remains in place while its settlement is monitored.
