Pile Dynamic Load Test Service

We are the leading service provider in Visakhapatnam, Andhra Pradesh, India and providing Pile Dynamic Load Test Service to our valuable customers. Pile dynamic test is used to assess the load bearing capacity of the pile. This test uses a hammer of a couple of tons to drop on the pile. Displacements are measured using a high tech instrument. This data is processed to arrive at the pile dynamic load bearing capacity as per IS-2911(part-1 section-1). This test is easy to conduct and requires very few site arrangements. The methodology of test is based on a large weight giving a dynamic impact to the elastic body. It equates the energy of hammer blow to work done in overcoming the resistance of the founding strata to the penetration of the ordinary cast-in-situ piles as well as grouted micro piles. Allowance is made for losses of energy due to the elastic compression of the pile, subsoil as well as losses caused by the impact of the pile. The modified Hileya s formula given in the code I.S. 2911 part 1 a section 1 is used in estimating the ultimate driving resistance in tonnes. From that with a factor of safety as outlined in the code the safe load on pile can be worked out. The instantaneous displacements including rebounds of the pile are precisely recorded in an automatic data acquisition system. This is done for several cycles & then using formulae as in I.S. 2911, the safe load capacity of the pile is calculated.
