The SCXT3000 system is a self contained sonic logging system, suitable for testing concrete piles, barrettes, diaphragm walls and any mass concrete structure. It is supplied with a military spec rugged notebook computer as standard, to enable the operator to work in arduous site conditions—right at the pile head.

The stainless steel electronic winch logs the depth tested and is also used to control acquisition of data if required. This enables the system to be easily operated by one man if required. Transducer cables can be supplied in 50m, 100m or 150m lengths and are fitted with submarine type connectors, also compatible with CS87 or CS97 type transducers.

The complete analysis software is used on site, enabling defects to be assessed in detail at the pile side if required. The same software can be used without licence for other users if required.

Features

  • 80GB of storage
  • Rugged Notebook sealed to MILSTD‐810F and MIL‐STD‐461E
  • Sunlight readable colour LCD screen as standard
  • User friendly windows based software for producing reports
  • 2D & 3D tomography software
  • Operates from 12VDC or 110/240VAC
  • Compliant with ASTM 6760 & AFNOR NFP94‐160‐1
  • Calculation of FAT & Energy changes

Software

The full SCAP software version is supplied as standard, including tomography options. Spanish and French language versions are also available.

The software enables the user to produce complete reports, including a pile data sheet, to show tube references, levels, depths tested, plumbed lengths and interpretation. Signal threshold levels can be selected both manually and automatically. The waterfall plot, signal energy plot and FAT (first arrival time) plots can be displayed individually or together, enabling the user to differentiate between features such as tube debonding and true concrete defects. Each individual signal is also stored for post analysis if required.

Whilst the 2D & 3D tomography modules provide an easy to understand visual, changes in FAT and energy can be calculated for more quantitative analysis.

Methodology

Cross‐hole sonic logging uses ultra sonic transducers to measure the transit time of sound in concrete. The test is carried out in foundations where steel tubes have been 
installed during construction, normally to the full depth.

As the winch wheel turns, the emitter sends an ultra sonic signal, which travels between selected tubes to a receiver. The signal, which is approx 50 – 60KHz, is captured and stored as a time/amplitude trace every 1 or 2cm of the pile length. 

The single traces are combined into one "sonic profile” or waterfall plot. A typical pile would have 4 tubes enabling 6 profiles to be taken. The operator can choose to display the FAT and signal energy simultaneously if needed. The first arrival time can be used to determine the ultrasonic pulse velocity if the distance between tubes is measured.

2D and 3D Tomography software enables you to produce an easy to understand overview of the spatial extent of any defects.
