Description

High-Strain Pile Bearing Tester

Model: RSM-PDT(B)

    

Application

Ø  High strain bearing capacity detection of pile

Ø  Low strain pile integrity detection by reflected wave method (optional)


Applicable standards

Ø  Standard Test Method for High Strain Dynamic Testing of Deep Foundations ASTM D4945-12

Ø  Technical Code for Detection of Building Foundation Pile JGJ 106-2014

Ø  Dynamic Testing Technology Regulations on Highway Engineering Foundation Pile JTG/T F81-01-2004

Ø  Nondestructive Detection Code for Railway Engineering Foundation Pile TB 10218-2008


Principle

l  Working Principle:

RSM-PDT(B) tester will provide prediction on the pile bearing capacity, pile integrity, driving stresses and hammer performance for a given pile penetration. It is a relative low cost type of pile testing compared to static load test (MLT or CRP). The testing technique is quick and accurate.

 

RSM-PDT(B) tester also can be used to perform high strain pile bearing monitoring (HSPBM-Monitoring) to evaluate pile driving information for pile bearing capacity, pile integrity, driving stresses and transferred energy against pile penetration. The results are essential for the actual pile driving process and to obtain valuable data on the hammer, pile & soil system for re-design on the piled foundation (if necessary).
