Description

RSM-PDT(B) High-Strain Pile Bearing Tester is a state-of-the-art testing equipment to perform high strain pile bearing testing on piles.

Working Principle:
HSPBT-Testing 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.

HSPBT 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).

Application:
1. Bearing capacity test for high strain of foundation piles.
2. Pile driving monitoring.
3. Integrity testing by pile low strain reflected wave method (optional)

The HSPBT-Testing is conducted in accordance to: American Society of Testing Material, ASTM D4945: Test Method for High-Strain Dynamic Testing of Piles.
Chinese Standard, JGJ 106: Technical Code for Testing of Building Foundation Piles and other relevant codes.

Characteristics:
1.High sampling speed, 120 hammer blow per minute.
2.10.4 inch true color LCD, backlight adjustable,direct and clear display.
3.Multi-core 16-bit A / D combination design, Large dynamic range,high SNR.
4.Real-time monitoring of sensors during fixing stage.
5.Auto balance of strain, offset zero drift of the signal.
6.Touch screen operation, friendly software interface and simple operation.
7.High-strength aluminum alloy chassis, light weight, dustproof and waterproof.
8.Analysis results of the CASE method,F-ZV Curve and the wave up and wave down curves.
9.Compatible with mainstream connector and sensor in the market.
