12 07 2021 nbsp 0183 32 Routine Vertical Pile Load Test Step by Step Pile Test The pile head was chipped off carefully till sound concrete was met with The projecting reinforcement was cut off and the top finished smooth and any uneven surface was made good with concrete A 16 mm thick bearing plate was placed on the prepared head to receive the jack base plaster of paris was Preparation for initial Pile Load Test Concrete cubes were taken during the test pile s concreting to be tested for seven days and 28 days Compile concrete cube test results and ensure that concrete has gained the desired strength Excavate around the test pile up to the bottom of the pile head to be built 30 09 2013 nbsp 0183 32 Methods of Testing Maintained Load Test The maintained load test is a better method This method provides an idea of both shaft and end Distance of anchor piles from test pile The distance cannot be less than 1 5 m It should not be less than 4 times the Load Measurement Settlement Load Test on Piles – Methods of Pile Load Test Initial Load Tests on Piles This test is performed to confirm the design load calculations and to provide guidelines Routine Load Tests on Piles Selection of piles for the Routine Test is done based on number of piles required subject Vertical The Test Method Loading is functional to the test pile through a calibrated hydraulic jack and where necessary a calibrated load cell calculates the load Throughout the SLT direct measurements of pile displacement under the applied loading are assumed by reading deflectometers dial gauges reading to 0 01mm which are arranged on glass reference plates

Pile Load Test Pile Loading Test Pile Load Test Procedure Pile

Pile load test procedures can change slightly from region to region depending on the local building codes A pile is driven and a load is applied to the pile Fig 24 1 is a highly simplified diagram of a pile load test Nevertheless it shows all the main parts that are needed to conduct a pile load test Figure 24 1 The test procedure is conducted in according with ASTM 1143 Procedure A Quick Test The pile capacity acceptance or failure criteria will be determined by the parameters established by the structure design and geotechnical engineer The Static Pile Load Test causes a failure along the soil pile interface This failure generally occurs well before the ultimate structural capacity 12 07 2021 nbsp 0183 32 Routine Vertical Pile Load Test Step by Step TEST PILE The pile was cast in situ in a bore taken to a depth of m from ground level Boring was accomplished by direct mud circulation method using bentonite slurry to stabilize the borehole The concrete was placed in the borehole after insertionThe Bi directional test is an alternative for the Static Load Test for bored concrete piles Characteristic of this type of pile testing is that the load is applied somewhere halfway in the pile instead of at the top of the pile By Construct a weighted box or platform Fig 2 over the test pile supported on cribbing or on other piles installed after the test pile a Cribbing Support For driven piles drilled shafts or micropiles locate the nearest face of the cribbing support not less than 10 ft 3 m or 5 test pile diameters whichever of the two criteria

Chapter 8 Static Pile Load Testing and Pile Dynamic

The test procedure involves applying an axial load to the top of the test pile with one or more hydraulic jacks The reaction force is transferred to the anchor piles that go into tension in the case of a static load test in compression or into compression in the case of a static load test in tension and wave equation type analytical procedures to predict soil behavior including static load capacity soil resistance distribution pile soil load transfer characteristics soil damping and quake values and pile load versus movement plots e g a simulated static load test CAPWAP analysis is made on the PDA data after the test is complete High Strain Dynamic Testing Load Test Setup The setup of the load tests consists of three major tasks 1 Mounting the pile cap onto the reaction floor 2 Application of the vertical load to the pile and 3 Application of the lateral load to the pile 5 4 1 Mounting pile caps on reaction floor Six threaded rods are placed in each pile cap during construction such that the rods extend out of the cap On each side of a load on the test pile is taken as twice the jacking load The instruments and measurements for the pullout tests are similar to those for compression load tests TESTING PROCEDURES Details of different testing procedures can be found in many publications e g ASTM Dl 143 81 Fuller and Hoy 1970 Crowther 1988 Joshi and Sharma 1987 Hirany andDynamic load test on piles is carried out by fixing strain sensors and accelerometers to the sides of the test pile below 1 5 times of pile diameter or higher from the pile head top and then connecting them with PDA Test pile should be extended to 1 6 times pile diameter after chipping top loose concrete In the case of the liner pile two
