Hydroelectric with soil nail

Soil nail is widely used in railway construction, Tunneling, mining, hydropower station, dam, bridge base, foundation reinforcement of buildings. Furthermore, it is workable for the repair of ground subsidence, hole collapse, crack, landslip and other geological disaster. Sinorock self drilling soil nails have been used in many famous hydroelectric projects, such as Nepal Rasuwagadhi Hydroelectric Station project, Nepal Upper Tamakoshi Hydroelectric Project and Ecuador TOPO Hydro-power Station, etc.,and have received a great reputation.
Sinorock always insist on safe, efficient, energy-saving and environmental friendly principles, and we will provide one-stop service, integral solution and quality guarantee.
Especially in the sand gravel stratum, using the traditional method of anchoring, the low probability of pore formation makes it difficult to grout and anchor lately and also increases construction costs.
At this time, self drilling soil nail shows its superiority, which can adapt to a variety of complex geological conditions and construction environment, particularly in the soft soil and sand gravel stratum.
Five performances about self drilling soil nail.
1.Self drilling soil nails is made of seamless steel pipe,whose surface is processed into thread, which can make it drilling, grouting and anchoring at the same time during the construction process.
2. Self drilling soil nails matches kinds of drill bits with specific properties, applicable to all types of formations.
3. It uses mechanical cutting technology for processing high-strength couplings, which makes self drilling soil nails has extended while drilling. It is able to use a longer self drilling soil nail in a small construction space.
4. As a result of using the self drilling soil nail as a drill rob, there is no need pre-grouting and using a casing.
5. Grouting is convenient and compact, increasing anchoring strength. Easy to use and have a higher construction speed.
