The saximeter (SAX-Q) is a rugged, dependable digital blow count device used for pile driving monitoring. The SAX-Q saves data into a predetermined and customized data format for every blow in the proprietary Detailed Drive Log (DDL), which cannot be edited once defined.

During driving the SAX-Q detects a hammer impact by either a built-in sound recognition circuit or by manually tapping a button on the device screen. As the hammer impacts the pile, the SAX-Q determines the time elapsed between consecutive blows, Δt, and converts this to equivalent Blows Per Minute, BPM, while also converting Δt to the stroke of an open-end diesel ram. The collected data is used to determine average values per penetration increment, for display and saving.

The SAX-Q main unit allows entering the basic project, pile, and hammer information and can be customized with additional pile driving information. The software includes a built-in hammer database, with information from most hammer manufacturers for a streamlined and simplified experience. If additional computation is needed, the device can save the collected data in tab-separated text files, for further processing using any Spreadsheet application (Microsoft® Excel or equivalent).

Using the SaxPlan program, the user can create Plans for their projects. These Plans are divided into “Footings”, each one containing an unlimited number of piles. The SaxPlan program generates a file containing all the Plan information. This file is then exported to the devices that will be used for testing the piles on a given job. Several files can be exported to a given device. Optionally, the Plan can be sent to a secure Cloud server.

Upon entering pile data, the user will select the Plan and Footing, producing an illustration of all piles. The user can then select the individual pile and the type of test to be performed. Once completed, the data will be saved in the DDL file, which will be uploaded to the Cloud or copied to a USB memory device. The saved and un-editable data is then added to the SaxPlan database.

The SaxPlan program will then be able to generate detailed drawings of the footing, showing the piles and their respective driving and restrike information.
