ASTM D (Ultrasonic Crosshole Testing).pdf – Download as PDF File .pdf ), Text File .txt) or read online. Crosshole sonic/ultrasonic logging (CSL) system for pile and deep foundation testing using ASTM D complete control from Panasonic Rugged tablet with dedicated Android application; conforming to ASTM D; wireless technology: WiFi – GHz .
Where defects exist, the extent, nature, depth, and approximate lateral location of the defects can be determined with the CSL method and further refined with Tomographic Imaging Softwarewhich is sold by Olson Instruments.

Integrated wireless system with 2 motorized reels; expansion options for 1 – 2 channels; with multi-reels system up to 4 the tomographic investigation is performed providing complete information on pile quality astn homogeneity over its whole length; the system is completely managed via a rugged Android tablet included ; easily transportable with the very small wheeled suitcase; user-friendly and intuitive software. The ashm can directly manage up to 4 motorized coil systems from one tablet.
All of Olson Instruments have been researched, tested, and used on-site daily by our sister company, Olson Engineeringworld reknowned for NDT consulting. How one applies the results obtained using this standard is beyond its scope. The method is limited primarily to testing the concrete between the access ducts and thus gives little information about the concrete outside the reinforcement cage to which the access ducts are attached when the tubes are attached to the inside of the reinforcement cage.
No other units of measurement are included in this standard.
Contact Olson Instruments when adding on to an existing system, or purchasing multiple systems as some of the components are common to other test methods. Integrated motorized reel including the 52Hz probe with 60 m cable; battery and control panel. The data are acquired at d670-08 pulse and displayed in real time on the tablet screen allowing any imperfections in the structure being inspected to be seen immediately.
Complete Cross-Hole system with 2 motorized reels. The OE Website is loaded with Tech Brief and project photos using the equipment shown on this website.
The Crosshole Sonic Logging system is the most accurate and reliable technique for assessing the integrity of deep foundation elements constructed on-site from concrete or grout. The method does not give the exact type of defect for example, inclusion, honeycombing, lack of cement particles, etc. 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.
These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard. The system is designed for Quality Assurance QA testing of newly placed critical drilled shaft foundations and auger cast piles, but can also be applied to slurry walls, mat foundations, and mass concrete pours.
Complete set, easily transportable with the very small wheeled suitcase. The Single-Hole Sonic Logging method is used in cases where only a single access tube can be placed in a deep foundation, and tests the concrete quality in the region around the single access tube.
Complete Cross-Hole system with 2 motorized reels, on site application. This method can also be extended to diaphragm walls, barrettes, dams etc. An wstm 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 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. Plans, specifications, provisions, or combinations thereof prepared by a qualified engineer, and approved by the agency requiring the test smay provide additional requirements and procedures as needed to satisfy the objectives of a particular test program.
Training may be available at your location by one of our agents upon special arrangement. The instrument is a complete system for performing structural tests by ultrasound on piles, deep foundations, infrastructural works or buildings.
The procedure for running adtm surveys with 2, 3 or 4 channels is managed in a fully automated way. The speed of the sonic wave and its energy are strongly influenced by the quality of the concrete and it is therefore possible to d6760-8 the characteristics and give a tomographic representation in 2D and 3D called diagraphy.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Cross-Hole Analyzer for foundation piles Wireless modular version
Using water-filled access tubes, CSL testing provides assurance that the foundation concrete is sound with no defects such as soil intrusions, necking, sand lenses, voids, etc. For complete details about the Crosshole Sonic Logging Systems available as an add-on test with the Freedom Data PC platform, call toll free or email: The cross-hole method is a way to analyze the foundation piles of buildings, which, with the use of cross-hole ultrasonic pulsesallows accurate, high-resolution tests to be carried out.
Using 2, 3 or 4 motorized reels it is possible to aastm the survey productivity and reduce testing time: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. December 31, Available NOW! This method is most applicable when performed in tubes that are installed during construction.
