Pile testing, pile load testing dynamic pile load testing provider company in India

Pile testing, dynamic pile load testing, static pile load testing & integrity testing

 Pile testing / Dynamic Pile Load Testing / Piling Testing services provider in India

Dynamic Pile Load Testing provides:

• Immediate results for each hammer blow
• Detection of extent and location of pile damage
• An indication of soil resistance during driving, restrike tests indicate soil set-up or relaxation
• Ability to trace potential problems to hammer, pile or soil
• Improved quality control

Pile testing / Dynamic Pile Load Testing is performed by attaching reusable, high quality sensors to the pile wall to monitor the force and velocity of a stress wave imparted into the pile head by a suitable falling weight. Testing is normally carried out using the contractors piling plant, however, ESG can supply a self contained 1.5 tonne drop hammer system suitable of demonstrating up to 120 tons and ideally suited to the bored pile market.

Data is collected and stored automatically on a blow by blow basis to aid decisions during pile driving and can be further evaluated using the CAPWAP method which uses the measured data with a pile model to calculate soil behaviour and simulated load deflection curve.

Pile Foundation, deep Foundation work and Pile testing services in India

Pile foundation work and Pile testing services provider in India

Pile foundation company has the india's largest consistent database of load test results. Our pile testing company has also collected vast experience covering all aspects of pile foundation or deep foundation construction and design on over 500 projects. This powerful combination makes us uniquely positioned to provide a valuable consultancy for a variety of complex Pile foundation or deep foundation projects.

Uses of Pile Foundations

Piles Foundation are long and slender members which transfer the load to deeper soil or rock of high bearing capacity avoiding shallow soil of low bearing capacity the main types of materials used for piles are Wood, steel and concrete. Piles made from these materials are driven, drilled or jacked into the ground and connected to pile caps. Depending upon type of soil, pile material and load transmitting characteristic piles are classified accordingly. Pile is also used for tall structures. In pile foundation load coming from the super structure is taken by pile cap and equally distributed in no of piles. Pile transfers this load in to the soil.

A pile is a type of foundation commonly used in property construction. Piles foundations are used as a substitute for other foundation methods when earth around the property isn’t strong enough to support conventional foundations. Piles are used to stack up more layers of soil and keep them walled in, providing a firmer base. Pile foundations are used to support marine structures and offshore platforms, since they are located over bodies of water. On land, pile foundations are used primarily in locations where poor soil conditions exist.

Pile Load Testing in India
Pile foundation or deep foundation can be constructed depending on the stiffness of subsurface soil and ground water conditions and using a variety of construction techniques. The most common techniques are in-situ casting and pre-augering. Due to the extensive nature of the subsurface mass that it influences, the degree of uncertainty regarding the actual working capacity of a pile foundation or deep foundation is generally much higher than that of a shallow footing.

Pile Integrity Testing / Sonic Echo Testing services:

Pile Integrity Testing -PIT performs Low Strain integrity testing, also called Sonic Echo Testing or Pulse Echo Testing. The Pile Integrity Testing -PIT may be used for auger cast-in-place piles, drilled shafts, driven concrete piles, concrete filled pipes and timber piles. It detects potentially dangerous defects such as major cracks, necking, soil inclusions or voids on any type of concrete foundations prior to construction of the superstructure. It may also test piles integrity in the structure, such as those supporting existing bridges, towers or any high rise structures and determine their length.

Dynamic Pile Testing service in india:

Dynamic pile testing constitutes a comprehensive and economical means to quantitatively evaluate the hammer-pile-soil system based on the measurement of pile force and velocity records under hammer impacts. Measurements, data processing and analysis are performed in real time in the field by state-of-art dedicated pile testing equipments. Pile testing results include estimation of pile load capacity, dynamic pile stresses and structural integrity & driving system performance. The Pile Driving Analysis is applicable on Bored cast-in-situ, drilled shafts, continuous flight auger & driven piles, this applies for either test pile or working pile.

Static pile load testing service in India:

The static pile load test is the most common method of testing the capacity of a pile and it is also considered to be the best measure of foundation suitability to resist anticipated design loads. The static load test involves the direct measurement of pile head displacement in the response to a physically applied test load. This test provides very reliable data for pile capacity. The capacity is actual structural or geotechnical capacities, not calculated from idealized data. This can allow for a lower factor of safety in the design if the pile performs better than expected.

Static pile load testing is one of the most common methods for testing the actual in-situ capacity of a pile.

Pile load test program involves the direct measurement of pile head displacement in response to a physically applied load. The test pile is loaded using a calibrated hydraulic jack that applies the test load to the pile by pushing against a beam placed directly over the test pile. The test beam is restrained by an anchorage system consisting of reaction piles installed in the adjacent ground to provide tension resistance. Once the load test frame is in place and fully instrumented, the hydraulic jack applies the test load in a series of increments according to the testing requirements specified by the project’s engineer. Each load is held for a predetermined amount of time until either twice the design load or pile failure is reached, whichever comes first. Pile movement is recorded with each incremental load, and the results are typically presented in a graphical format to the structural engineer of record.

Piles can be tested for compression, tension or lateral loads. By providing actual capacity and deflection values, the test results can be used to confirm that the pile design load can be adequately supported. Depending on the test pile’s performance, the results may also allow for project cost savings by permitting an increase in the pile design load, a reduction in the overall pile length, or a quantification of capacity in difficult or unknown soil conditions. Additionally, the results will offer an improved knowledge of pile-soil behavior, as well as provide valuable data that can be used for future research.
