Abstract

The invention is an application that completely alter the operating principle and load transfer mechanism of the anchorage technique used in the field of civil engineering, in particular at the excavation bracing and slope stability applications with a novel root zone apparatus.

Claims

1. The invention relates to an anchorage system used particularly in excavation supporting and slope stability applications in the field of constructional engineering characterized in that it comprises:

Open-Close ring (1.3) comprising multiple lower connection brackets (1.3.1) that are fixedly and mountedly positioned, that allow the coupling of the support elements (1.3.1.1), that is positioned anywhere on the anchorage body (1) and that open cutter vanes (1.2.1) by means of enabling the movement of support elements (1.3.1.1) and multiple cutter vanes (1.2.1) cutting the surface during the deployment of umbrella-shape anchoring,

Multiple support elements (1.3.1.1) that ensure cutting wings (1.2.1) to assume a vertical position by anchoring body (1) during the deployment of umbrella-shape anchoring by the movement of open/close ring (1.3) towards the surface where the anchoring shall be performed,

Guide tube (2) that gets fixed to anchoring once the anchoring is inside the hole after the anchorage body (1) it owns drives the anchoring to desired depth and that ensures the anchorage cable (4) to remain at the center,

Anchoring cable (4) that ensures the anchorage body (1) it comprises to pass through the hollow tube form,

Grouting ring (1.3.2) positioned at the lower part of open/close ring (1.3) and that ensures the formation of a composite structure between cutter vanes (1.2.1) and cement grouting by injecting cement water into the well.

6. Anchoring system according to claim 1 characterized in that;

the grouting ring (1.3.2) assembled and fixed on the Open-Close ring (1.3) of the system has a diameter larger than the Open-Close ring (1.3).

7. Anchoring system according to claim 1 characterized in that;

the lower connection brackets (1.3.1) are the protrusions where support elements (1.3.1.1) are vertically positioned to open-close ring (1.3) are to be coupled.

8. Anchoring system according to claim 1 characterized in that;

the grouting ring (1.3.2) is positioned on the Open-Close ring (1.3) and that has a circular shape wrapping around the Open-Close ring (1.3).

9. Anchoring system according to claim 1 characterized in that;

the grouting ring (1.3.2) it has;

comprises an grouting pipe (1.3.2.1) in hollow tube form that originates from the grouting ring (1.3.2) and extends over well outlet located at the ground surface.

11. Anchoring system according to claim 1 characterized in that;

the grouting pipe (1.3.2.1) it comprises;

contains grouting coupling (1.3.2.1.1) at the end that is not connected to the Open-Close ring (1.3).

14. Anchoring system according to claim 1 characterized in that the anchorage body (1) it has, comprises a cable locking apparatus (3) that is positioned at anchoring end once the anchoring is settled inside the hole and that ensures passing the anchorage cable (4).

16. Anchoring system according to claim 1 characterized in that, comprising tensioning element manufactured out of fabric on the cutter vanes (1.2.1) it comprises, that ensures the coupling between cutter vanes (1.2.1) that is positioned in a way covering the cutter vanes (1.2.1) that enables the collective movement of all cutter vanes (1.2.1) during the deployment of cutter vanes (1.2.1), that distributes the inbound weight imposed on the cutter vanes (1.2.1) to a broader area and that enables the injection by discharging in-between surface areas.
