Wireless and Modular Cross-Hole Analyzer for Foundation Piles

How it works

An ultrasonic wave is sent from a transmitter to a receiver and is conveyed automatically by the device along the entire length of the pile via the pipes embedded into it during casting. The speed of the sonic wave and its energy are strongly influenced by the quality of the concrete and it is therefore possible to assess the characteristics and give a tomographic representation in 2D called diagraphy.

Cross-Hole Analyzer, a complete system

The instrument is a complete system for performing structural tests by ultrasound on piles, deep foundations, infrastructural works or buildings.

Each reel system has a 52 kHz motorized probe with 60 m of cable and also houses the battery plus all the electronic controls that automatically manage the probes during the descent/ascent phases (cross-hole) and saving of the test data.

The configuration practically eliminates the need for physical cables and is supplied with a Rugged tablet which allows the setting of all parameters, test management, and display/processing of the acquired test data in an easy, immediate and wireless way.

The system can directly manage up to 4 motorized coil systems from one tablet.  Using 2, 3 or 4 motorized reels it is possible to increase the survey productivity and reduce testing time: with a single ascent/descent of the probes in the pile to be checked (which must have 2, 3 or 4 integral pipes) it is possible to obtain results for the corresponding sections.
The data are acquired at each pulse and displayed in real time on the tablet screen allowing any imperfections in the structure being inspected to be seen immediately.

Fully automatic

The procedure for running cross-hole surveys with 2, 3 or 4 channels is managed in a fully automated way. The only manual operations required are the positioning of the encoders for reading the position of the motorized probes on the pipes and the initial alignment of the probes on the pile head.
The test is started by simply pressing a button and it is possible to verify the test data step-by-step in order to check the test progress in real time.
