Infrastructure Construction Investigation

Product Features

Comparing to the traditional drilling equipment, EGR’s advanced portable, fully-hydraulic equipment, thin-wall coring technique and in situ testing approach can significantly increase the drilling efficiency and quality, as well as reduce accidents and costs. Aiming at promoting efficient, quality, safe and environmental friendly drilling, EGR helps boost the development of infrastructure investigation in railway, highway, bridge, tunnel, water conservancy and hydropower areas.


Challenges of the Industry

Traditional drill rig is now hard to meet the high requirements of today’s geological investigation due to its heavy weight, low efficiency, poor quality, high labor intensity, low safety and high costing issues, especially when drilling in terrains with various formats, as well as for projects that are operated in high risk areas with high environment standard and shorter timelines.



    New equipment:the lightweight design and materials can reduce compensations for young crops and land use; modular design can be assembled based on different needs for all terrains, all scenarios and all applications; thin-wall coring technique can ensure high efficiency, quality and safety; tools from leading brands to reduce waiting time.

    New techniques:thin-wall coring techniqueintroduced to infrastructureconstruction; the “standard-penetration serial hitting without lifting drill”approach to increase efficiency, safety and accuracy.

   New approaches: The single-engine double-tube wireline coring technique is used to replace the hammer-sampling approach, which can greatly increase the efficiency. The disposable plastic inner tubes can also be used to avoid incorrect operations.
