Sinorock Launches Industry–University–Research Partnership with Henan University of Science and Technology on Self-Drilling Micropile Systems

Time:2026-07-03From:sinorock View:

Sinorock welcomed a research delegation from Henan University of Science and Technology for an in-depth technical exchange. During the visit, both parties officially launched a joint industry–university–research program focused on Self-Drilling Micropile Systems.

This collaboration is rooted in real engineering practice. By combining Sinorock’s extensive field construction expertise with the university’s strong research capabilities, the project aims to systematically investigate the mechanical behavior of single and group self-drilling micropiles, optimize construction methodologies, and study ground settlement mechanisms. A comprehensive research framework integrating theoretical analysis, laboratory testing, field monitoring, and numerical simulation will be adopted to advance the development and engineering application of self-drilling micropile technologies.

1. Technical Exchange and Project Framework Definition

Industry–University–Research Partnership

During the technical discussions, both parties aligned on research directions, technical focus areas, and implementation planning.

Sinorock’s engineering team presented its standardized construction methodology for self-drilling micropile systems, based on years of international geotechnical project experience. The presentation covered core working principles, full construction procedures, and quality control systems throughout the entire installation process, providing a solid engineering basis for subsequent research activities.

From the academic side, the Henan University of Science and Technology team defined the overall research framework, including key technical challenges, research methodology, and phased objectives. Both parties finalized task allocation, resource planning, and a structured timeline to ensure efficient and well-organized project execution.

2. Field-Based Experimental Research on a Real Engineering Project

Unlike purely theoretical studies, this collaboration is conducted within a real industrial building foundation project involving 290 self-drilling micropiles.

The experimental program serves as a key pre-construction research phase. The data collected from field testing will directly support subsequent construction optimization, design refinement, and standardization of technical parameters, ensuring both engineering reliability and practical applicability.

For field implementation, R38 self-drilling anchor systems with 150 mm drill bits are used, with a designed installation depth of 9 meters. The study covers single pile behavior, pile group interaction, pile–soil deformation mechanisms, and load transfer characteristics under real ground conditions.

3. Comprehensive Performance Testing and Deformation Monitoring

Field-Based Experimental Research on a Real Engineering Project

A series of performance tests have been designed to evaluate the bearing capacity and construction stability of the system.

Key testing activities include:

· Tensile and pull-out capacity tests on single micropiles

· Compressive load tests on 4-pile and 6-pile group systems with pile caps

To capture real-time mechanical responses during loading, strain gauges are installed along the reinforcement body to continuously monitor stress and strain variations throughout construction and loading stages.

In terms of soil–structure interaction, the study focuses on settlement and deformation behavior of surrounding soil during installation and service stages. Pile spacing is introduced as a key variable to analyze its influence on overall settlement and foundation stability, providing valuable insights for settlement control in complex ground conditions.

4. Integrated Validation Approach Combining Testing and Simulation

To overcome the limitations of single-method studies, the project establishes a multi-method validation system combining:

· Laboratory testing

· Full-scale field experiments

· Numerical simulation analysis

Using advanced geotechnical simulation software such as Abaqus, refined numerical models will be developed. Experimental data from laboratory tests and field measurements will be cross-validated with simulation results to better understand stress distribution, deformation mechanisms, and stability behavior of micropile systems under complex geological conditions.

This integrated approach enables continuous refinement of design parameters and construction methods.

5. Advancing Engineering Applications Through Practical Validation

Sinorock Self-Drilling Micropile Systems integrate drilling, grouting, and anchoring into a single operation, offering significant advantages in construction efficiency, adaptability to complex ground conditions, suitability for restricted-access environments, and overall system reliability.

These systems are widely used in fractured rock, unstable formations, foundation reinforcement, and the rehabilitation of existing structures.

Through this collaboration, high-quality field data obtained from full-scale engineering applications will help address the lack of refined performance data for R38 micropile group systems. The results will provide a solid scientific basis for future design optimization, pile spacing configuration, settlement control strategies, and parameter selection in similar engineering projects.

6. Conclusion

Moving forward, Sinorock will continue to strengthen its industry–university–research collaboration model, driven by real engineering data and scientific innovation. The company remains committed to advancing Self-Drilling Micropile Systems and geotechnical engineering solutions, delivering more efficient, reliable, and data-driven support technologies for global infrastructure development.
