What different tests are carried out on pile foundations?
Pile Foundation Design and Testing
- Static Pile Load Testing.
- High Strain Dynamic Pile Load (PDA) Testing.
- Crosshole Sonic Logging (CSL) – Pile Integrity Testing.
- Thermal Integrity Profiling (TIP) – Pile Integrity Testing.
- Low Strain Pile Integrity Testing (PIT)
- Downhole Pile Image Inspection Services.
What are different piling methods?
There are three types of pile foundations according to their construction methods which are driven piles, cast-in-situ piles, and driven and cast-in-situ piles.
What is pile load testing?
Static pile load testing is one of the most common methods for testing the actual in-situ capacity of a pile. The test program involves the direct measurement of pile head displacement in response to a physically applied load.
What is PDA test pile?
Technical Profiles. Dynamic load testing using Pile Driving Analyser (PDA) equipment is a high-strain non-destructive load test method which can be performed during or after pile installation using conventional pile driving equipment. This test can be applied to driven steel, driven timber and even concrete piles (eg.
What is Capwap pile testing?
Case Pile Wave Analysis Program (CAPWAP) is a software program that uses the force and velocity data obtained from the Pile Driving Analyzer to estimate shaft and end bearing capacity of the tested pile. It is also utilized to estimate the resistance distribution along the shaft and toe of the pile.
What is dynamic pile testing?
Dynamic load testing (or dynamic loading) is a method to assess a pile’s bearing capacity by applying a dynamic load to the pile head (a falling mass) while recording acceleration and strain on the pile head.
What is PTP in piling?
Preliminary test piles (PTPs) are often carried out as part of the enabling works mobilisation to verify the design immediately before the construction of working piles, leaving limited optimisation opportunities. This is due to several factors.
What is DMC piling?
DMC piling means Direct Mud Circulation piling. Here Installation of Pile Foundation is done Using Direct Mud Circulation Method (DMC). Direct Mud Circulation method is best suited when sufficient working-space is available for piling . The tools and machine required for DMC piling are. 1) Tripod with pulley.
What is CHD piling?
The continuous helical displacement (CHD) piling system is a form of cast in situ auger displacement pile that may be classified as a type of screw pile. As with driven/displacement piles, the soil is displaced around the CHD tool during installation, which is assumed to result in improved pile performance.
What is Sonic test for piles?
Cross-hole sonic logging test is conducted to determine quality of concrete for deep pile and identifies the defect location based on ultrasonic pulse velocity. Generally unit skin friction can be determined CSL and strain captured during O-Cell pile load test.
What is CAPWAP and Lwapp?
CAPWAP is an abbreviation for Control and Provisioning of Wireless Access Points protocol (CAPWAP), which is based on LWAPP, which is a standard, interoperable protocol that enables a controller to manage a collection of wireless access points.
