Abstract
The utility model discloses a double layer protection anchorage cable without bounding end for reinforcement of the rock, which comprises a ripple pipe. One end of the ripple pipe is provided with a guiding cap, the front end of the guiding cap is outlet of size, the steel stride cable is also arranged on the alignment shelf in the ripple pipe, the steel stride cable is connected to the anchorage tool, another end of the ripple pipe is provided with a protection cover for the outer anchorage head, an exhaust hole is arranged on the protection cover of the outer anchorage head, a grease injection hole is also arranged on the anchorage cable. The steel stride cable is bound in nut shape. The steel stride cable would apply un-bonded steel stride cable with grease and plastic bushing. The tension section of the device is protected by the grease plastic bushing and grout, the inner anchorage section is protected by the ripple pipe and grout, the steel stride cable takes measurement of double protection. The durability of the anchorage cable is improved; the un-bonded steel stride cable with grease and bushing is applied, the tension section of the anchorage cable is suit to the deformation of the rock. The capability of the anchorage body to protect against deformation is improved.
Description
Technical field
The utility model relates to a kind of anchor structure system that is used to reinforce rock mass.
Background technology
In recent years, the non-bonded anchorage cable of double-deck protection has become one of the most frequently used in the world anchor cable structure, has obtained using widely owing to it has the advantage that adapts to rock mass deformation.Existing non-bonded anchorage cable is compiled rope and is reeved and is not easily, and after the anchorage cable stretching locking, easily be corroded near space the aperture and the protective cover, termination anchor inner segment bellows easily produces the faces end head plugging problem.
Summary of the invention
The purpose of this utility model provides a kind of reeve and to compile rope convenient, and aperture section antiseptic property height, termination anchor inner segment bellows are difficult for producing the bilayer protection of faces end head plugging does not have bonding termination anchor cable.
The purpose of this utility model is achieved in that a kind of double-deck protection nothing bonding termination anchor cable; comprise bellows 1; bellows 1 one ends are provided with guiding cap 3; the guiding cap front end is a grout outlet 2; also be provided with the steel strand 5 that are installed on the centering shelf 4 in the bellows 1, steel strand 5 are connected with ground tackle 7, and bellows 1 other end is provided with outer anchor head protective cover 6; outer anchor head protective cover 6 is provided with exhaust opening 10, also is provided with grease on the anchor cable and adds inlet 8.Steel strand 5 are bundled into jujube nuclear shape by tying up silk 9.Steel strand 5 adopt the non-bending steel cable of band grease and plastic bushing.
Double-deck protection provided by the utility model does not have bonding termination anchor cable, after the anchorage cable stretching locking, all pours into anticorrosion grease near space the aperture and the protective cover and forever protects, high antiseptic property; Adopt the non-bending steel cable of band grease and sleeve pipe, the distortion of anchorage cable stretching section suitable for surrounding rock improves the non-deformability of anchor cable.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model adopts following structure: a kind of double-deck protection does not have bonding termination anchor cable; comprise bellows 1; bellows 1 one ends are provided with guiding cap 3; the guiding cap front end is a grout outlet 2; also be provided with the steel strand 5 that are installed on the centering shelf 4 in the bellows 1, steel strand 5 are connected with ground tackle 7, and bellows 1 other end is provided with outer anchor head protective cover 6; outer anchor head protective cover 6 is provided with exhaust opening 10, also is provided with grease on the anchor cable and adds inlet 8.Steel strand 5 are bundled into jujube nuclear shape by tying up silk 9.Steel strand 5 adopt the non-bending steel cable of band grease and plastic bushing.
Embodiment: anchor cable builder's tonnage 3000kN, super tension tonnage are 3450kN, anchor cable hole depth 30～60m, interior anchor segment length 8m, aperture 165mm.Steel strand 5 adopt the 1860MPa band grease of 19 Φ 15.24mm and the non-bending steel cable of plastic bushing.The design strength utilization factor is respectively 0.606, and super stretch-draw strength factor is 0.697.Interior anchor section peeling 5m, steel strand 5 are bundled into jujube nuclear shape by tying up silk 9.Anchor cable total length sleeving plastic bellows, bellows 1 is inside and outside all by Grouting Pipe 11 grout injections, and the anchor cable once grouting is to the aperture, and by grout outlet 2 pulps, the cement paste match ratio is identical with anchor section in the total length bonding anchor cable.Plastic film capicitor 1 is by the domestic-developed manufacturing, wall thickness 1.5mm, and wave height 5mm, internal diameter 91mm, external diameter 101mm can hold external pressure 1.0MPa.The centering isolating frame 4 of anchor cable is that polyethylene plastic products is also by special factory production.The anchorage cable stretching process is identical with total length bonding anchor cable.After the anchorage cable stretching locking, all pour into anticorrosion grease near space the aperture and the protective cover 6 and forever protect by the grease inlet.Exhaust opening 10 can guarantee the balance of air pressure.Whole anchor cable body has all reached double protection, as: interior anchor section has cement slurry and the two-layer protection of bellows; The stretch-draw section has cement paste, grease, sleeve pipe and bellows protection; Outer anchor head has grease and the two-layer protection of steel cage.This anchor cable is opened protective cover after operation a period of time, can compensate stretch-draw again behind the removing grease.
