Product Description

Hollow head mounted on the bolt body carbide drill bits, drill pipe to bolt body instead of drilling, drill the end of the connecting rod bolt body and the rock drilling machine connected with the rock drill perforated the design of a bolt depth, the installation only pulp plugs, pad plate, nut was conducted after the grouting. When the slope support or hydropower station construction, can also be used to replace large-diameter bolt hole drill pipe, carrying out drilling grouting and more powerful, than the anchor role in a stronger, more efficient and convenient, lower construction costs.

Advantages︰1. Hollow design, implementation of the grouting tube function, avoid the 
traditional grouting tube pulled out of the mortar caused by the loss. 
2. Grouting full, and can achieve the pressure grouting to improve project 
quality. 
3. Center is good, mortar bolt body length can be wrapped, to avoid corrosion, 
to supporting the long-term purposes. 
4. Easy installation, without on-site processing of threads, it can be easily 
installed an plate, nuts.
Export Markets︰Southeast Asia, Europe, South America
