Dalper Chile - Drilling tools
Belbor
Self-drilling bolts: suitable for difficult terrain
Autoperforador system cheaper and easier. Also suitable for difficult terrain clay, Sandy, friable, etc, it can be used as drilling rod. The placement of the anchor is made by injecting cement mortar directly over the center hole of the bar.
The fields of application of self-drilling bolts are:-vaults, side walls, slope stabilization and front of excavation in construction of tunnels.
-Stabilization and extension of existing tunnels - mircropilote screens - foundations of buildings - stabilization of hills and foundations - Foundation for protection against avalanches, protective walls against noise, high voltage poles, antennas, trams and laying electric, wall anchor, etc.
-Active dual protection the basic material of the Belbor anchor bolts is a special tube with little tolerance, the which on cold and continuous thread machining. The sleeves are made of special steel tubes and have greater resistance to stress that the bolt. The nuts are made of a special steel hot pressing and are treated after manufacture to ensure the required resistance.
