Two-phase a - and - jacket - of heavy-duty anchors even drilling as cartridges or ammunition rounds - or injection anchor in rotary impact strength embodiment provides. Production and setting procedure

摘要

As a - or two-phase cartridges or ammunition rounds -, - injection, more compartment jacket - of heavy-duty anchors, a hollow rod composite anchor, consisting of a plurality of tube layers which are welded to each other, which are connected with radial teeth, for the rotary blow solid use in the mountain -, tunnels, -, deep - and rock engineering, is provided with an at least partially into a hollow rod bore incorporated cartridges or ammunition rounds adhesive, with at least one anchor head is provided on the side of the combined - jacketed mixer, or in combination with a ausräummeißel and, optionally, with a drill bit, designed in such a way that, in order to achieve this in a few seconds, with an armature foot positioned on the side of the piston, the adhesive cartridge is pressed out.The outer surface of the jacket - heavy load armature, with a rolled-on, screw profiling which are capable of. An elastic abrasion-resistant connection for the reception of movements of strata, is provided between the inside - and outer pipe with the rolled-on radial toothing, between the tube walls is achieved. In the rotary blow solid design of the system would, is assigned to the cooling water for the drill bit, the inserted adhesive cartridge in the inner tube of the system would, vibration attenuator - and the rotary blow secured freely. The set anchor can be incorporated in the cartridge magazine that is squeezed out, with a solid rod be further enhanced.The set bi-phase cartridges or ammunition rounds -, - injection, more compartment jacket - of heavy-duty anchors, after the curing of the mixture, with a flat, because of the armature crosspiece and the integrated pretensioning element fixed in such a way that the armature preload of the anchor head, an accident when the appropriate produce the armature via state in the travel path forces are avoided and the outside of the armature bore, into the rock are derived.In order to achieve the vault is in the case of cartridges anchors, is the volume of the adhesive cartridge which is for the filling of all of the bored through fissures and columns of larger dimensions than the volume of the armature ring space.
