DIGGS Scheme for Rock Grouting Data Transfer-Paper

Paper

Pdf Summary

The paper describes a pilot extension of DIGGS, an XML-based standard for exchanging geotechnical data, to document rock permeation grouting. Supported by the Deep Foundations Institute, the project brought together owners, engineers, contractors, and researchers to define a shared data structure for grouting activities.<br /><br />The extension introduces a top-level `constructionActivity` element and a construction-activity base feature, allowing construction data to be represented alongside DIGGS’s existing exploration data. The new `RockGroutingActivity` feature links grouting work to the relevant borehole and can contain grout-mix information, grouting stages, summary results, and time-series measurements collected during injection. These measurements may include pressure, flow rate, grout properties, and grout take. The schema also accommodates Lugeon test data through DIGGS’s existing test framework, with modifications to borehole casing and backfill objects to represent repeated installation, removal, backfilling, and redrilling.<br /><br />The common format is intended to reduce manual data entry, file conversion, and transcription errors, while enabling data from drilling equipment, grout plants, and injection points to be combined and used more efficiently. DIGGS itself provides a consistent structure for data exchange; specialized software remains responsible for interpretation, visualization, and storage.<br /><br />The additions are available in DIGGS development version 2.6 for review and testing, with example XML files on GitHub. Future work is expected to extend the schema to other grouting methods, such as jet, compaction, and consolidation grouting, as well as other construction and monitoring activities.
