Abstract
Method and device for rock bolting, wherein a tubular bolt (2) with closed cross-section is inserted and expanded for anchoring inside a bore hole (12) , wherein the tubular bolt is expanded to contact in the inner portion of the bore hole, a tension element (3, 7, 8, 9) which is arranged in the outer portion of the bore hole with an inner part (7) attached to the tubular bolt (2) is pre-stressed and a settable medium is injected into the outer portion of the bore hole (14) between (27) the tension element and the wall of the bore hole and is allowed to set.
Claims (19)
1. Method for rock bolting, wherein a tubular bolt (2) with closed cross-section is inserted and expanded for anchoring inside a bore hole (12), which has an inner (15) and an outer (14) portion as well as an inlet opening (13), and wherein the tubular bolt is expanded to contact in the inner portion of the bore hole, characterized in - that a tension element (3,7,8,9) which is arranged in the outer portion of the bore hole with an inner part (7) attached to the tubular bolt (2) is pre-stressed, - that a settable medium is injected into the outer portion of the bore hole (14) between (27) the tension element and the wall of the bore hole and is allowed to set, and - that the channel for transmitting said settable medium is opened for communication to the outside (27) of the tension element (3) through pressurizing to a certain pressure level.
2. Method according to claim 1, characterized in - that medium for expanding the tubular bolt is transmitted through a channel (19) in the tension element (3).
3. Method according to claim 1 or 2, characterized in - that said settable medium is transmitted through a channel inside the tension element (3).
4. Method according to any of the previous claims, characterized in - that the channel is opened when a bursting plate (16) is made to break at said pressure level.
5. Method according to claim 1 or 2, characterized in - that said settable medium is transmitted (30) outside of the tension element (3).
6. Method according to claim 5, characterized in - that air being present inside the bore hole is evacuated (31) through a channel in the tension element (3) when injecting said settable medium.
7. Method according to claim 1, characterized in - that medium for expanding the tubular bolt is transmitted through a separate bolt installation element (28) which is attached to a connection portion of the tubular bolt (2).
8. Method according to claim 7, characterized in - that the tension element (3) is attached to said connection portion after expansion of the tubular bolt (2).
9. Method according to claim 1 or 2, characterized in - that the tension element (29) is attached through clamping between the tubular bolt (2) and the wall of the bore hole at the expansion of the former.
10. Method according to any of the previous claims, characterized in - that the tension element (3) is pre-stressed between the tubular bolt (2) and an abutment element (4) arranged at the inlet opening of the bore hole.
11. Device (1) for rock bolting, including a tubular bolt (2) having a closed cross-section for insertion into and expansion for anchoring inside a bore hole (12) which has an inner and an outer portion and an insertion opening, characterized in - a tension element (3) to be arranged at the outer portion of the bore hole having an inner part (7) for attachment to the tubular bolt, - means (10, 11) to pre-stress the tension element (3) in a length direction between the tubular bolt and the insertion opening, - means for transmitting a settable medium to the outer portion of the bore hole between (27) the tension element and the wall of the bore hole, and - that the channel for transmitting said settable medium provides means (16) which are opened for communication to the outside of the tension element through pressurizing to a certain pressure level.
12. Device according to claim 11, characterized in - means for transmitting medium for expanding the tubular bolt (2).
13. Device according to claim 11 or 12, characterized in - that said means for transmitting said settable medium includes a channel in the tension element (3).
14. Device according to any of the previous claims 11-13, characterized in - that said means which is opening is a bursting plate (16), which is made to break at said pressure level.
15. Device according to any of the claims 11-12, characterized in - that said settable medium is arranged to be transmitted (30) outside of the tension element (3).
16. Device according to claim 15, characterized in - an evacuation channel (31) inside the tension element for evacuating air being present inside the bore hole when injecting said settable medium.
17. Device according to claim 11 or 12, characterized in - a separate bolt installation element (28) which is fastenable to a connection portion on the tubular bolt (2) for transmitting medium for expanding the tubular bolt.
18. Device according to claim 11, 12 or 16, characterized in - that the tension element is provided with means for fastening to said connection portion after expansion of the tubular bolt.
19. Device according to claim 11 or 12, characterized in - that the tension element (29) is formed so as to be anchored through clamping between the tubular bolt and the wall of the bore hole at the expansion of the former.
