Definitions
- the invention relates to the rock anchoring method, for the purpose of their consolidation and Securing the adhesion of the massif in the construction of civil engineering works, Civil engineering workplaces, tunnels and chambers, when carrying out the slope stabilization and dam consolidation and various other technological applications in coal and ore mining and construction.
- Both known hydraulically clampable friction anchors have a common feature, which is based on the technical solution of its anchor part.
- This part forms a tubular body with a circular average, but longitudinally usually in the form of a deep groove is deformed or dented.
- the tubular body is closed at both ends, resulting in a hydraulic vessel.
- Anchor effect is at these anchors achieved due to the frictional force on the peripheral surface of the tubular body, of the Restvorschreib the pipe body is triggered after its hydraulic straightening.
- the axial force transmitted by the anchor body is then proportional to the average and quality of the applied pipe material.
- Limit for transmission of traction Material properties of langver acknowledgedd deformed tube because of necessary Extensibility when expanding must have a certain maximum strength.
- This method is also based on its variables, which were given before the introduction of the Pressure fluid into the longitudinally deformed inflatable tube, i. before restraint of Reibankers are applicable in the bore.
- the rods are first in the whole groove length of the cavity in the longitudinal deformed hydraulically inflatable tube of Reibankers or in a part thereof inserted and placed together with the Reibanker in the hole.
- the rods become hydraulic in the whole groove length of the longitudinally deformed inflatable tube of the friction anchor or inserted into a part of it and then the rods are firmly connected to one or both ends of the Reibankers and shared with the Reibanker inserted into the borehole.
- the rods are first provided with a head at one end and are placed in the Groove of the longitudinally deformed hydraulically inflatable friction anchor until stop of the Kopf is inserted or becomes a certain play between rod heads and the End of the inflatable tube and left together with the Reibanker ins Drilled hole inserted.
- the bars are inflated after insertion into the groove of the longitudinally deformed Pipe of Reibankers first secured against falling out of the Reibanker and put together in the borehole.
- rock anchorage is the anchorage effect on the mountains by a suitable combination of qualitatively used qualitative materials own hydraulically clamped Reibanker, or in its longitudinally deformed Pipe and raise at the bars.
- the in extensibility and Strength of different material in the applied Reibanker and parallel to it arranged rods in the mountain borehole is favorable the load characteristics of Anchor, i. it is its carrying capacity both full length, as well especially by strengthening its hitherto weakest part to increase the usually the head of the Reibankers is.
- the rods can be equipped with a head at one end.
- rock anchorage according to the invention is in underground and building construction, in mining, at Tunell and collector construction and everywhere applicable where previously for anchoring standard hydraulically clamped friction anchors with a certain rated load capacity be applied and where necessary, at anchor operational at the workplace and planned their carrying capacity and thereby also the final anchoring effect on the To raise mountains
