FAQs
Q
Q4:What is Minimum/Maximum Diameter and Minimum/Maximum Depth of Pile can be tested by this device?
+
A
A: maximum and minimum diameter is unlimited, the depth requirements meet the principle requirements of one-dimensional stress wave rod. Because the high strain test energy is large and the incident pulse width is wide, the requirement for the length diameter ratio of the pile is greater
Q
Q3: What must do if we cannot repeat hammering on site?
+
A
A: If the pile does not meet the conditions for repeated test, pre acquisition is required before the test to ensure that effective signals can be obtained by one acquisition
Q
Q2: How much minimum settlement could accept when testing in field?
+
A
A: It is determined according to the selected standard requirements. The requirements of each standard are different. The Chinese construction industry standard is 2-6mm，In Chinese Mainland, a large number of experimental data show that the bearing capacity results obtained when the pile settlement after hammering is within the range of 2-8mm are the most accurate.
Q
Q1: when is the right time to do a PDA test on the foundation piles
+
A
A: The specific test period should refer to the requirements of the corresponding specification or standard. According to a lot of testing experience, for Bored piles, the PDA test can be carried out when the pile foundation reaches the strength requirements after about 28 days of pile formation; for RC piles or Spun pile, the pile rest period should be reached, and the test should be carried out about 14 days after Piling.
