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.
