Micropiles are rapidly gaining popularity for foundations in urbanized areas or in locations 

with low headroom and restricted access. They are an ideal choice for underpinning or 

emergency repairs because they can be installed in virtually any ground condition with 

minimal vibration and disturbance to existing structures.

Hollow anchor bolt has been largely used as an economical and efficient method for slope 

stabilization in highway projects. With novel structure, advanced technology, reliable 

quality, strong adaptability and good durability, hollow anchor bolt will have vast 

potential for future development. And it will become a mark for the progress of geotechnical technology in the world. 

Self drilling hollow bolts are ideal for micropiles, soil nails, and tie down and tie back 

anchors in difficult ground conditions like weathered and decomposed rock, round gravel, 

sand and clay soils for either permanent or temporary use. The hollow bar technology 

characteristic integrating drilling, grouting and anchoring is of great significance to 

realize complex geological conditions of anchorage.Sinorock Self Drilling hollow Bolts are 

based on a 3-in-1 concept. The hollow steel bar acts as a drill rod, a reinforcement bar and 

a grouting pipe. Therefore,Sinorock Self Drilling hollow Bolts are suitable for both 

permanent and temporary applications, including the most difficult ground conditions.
