Self drilling anchors are a new type of anchorage technology and are used in tunnel advance support, foundation pit construction and slope protection. When developing in different areas, it may encounter different complex geological conditions, but self drilling anchors can solve these problems. Self drilling bolts combine drilling, grouting and anchoring to complete multiple processes at the same time, saving time and efficiency. When loose and broken surrounding rocks are encountered, the drilling rate is very low in the traditional way. The self drilling bolts can be grouted and anchored while drilling to prevent the collapse of the drilling holes. The grouting material flows into the fractured rock gap, which not only enhances the anchorage of the rock, but also blocks the groundwater erosion of the engineering foundation. Even in geological conditions such as wetlands and soft soils, self drilling anchors can be anchored to the projects. Sinorock® is unanimously committed to providing system solutions for rock and earth anchorage projects around the world, and to be a safety guardian of geotechnical anchorage engineering. Sinorock® rock bolts have become anchoring support forces for numerous projects.
