Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1:
Figure 1 illustrates a kind of structure of this utility model large aperture grouting cable anchor.It is made up of the shell anchor head 1 that rises, cable body 2, stop grouting plug 3, pallet 4, ground tackle 5.Cable body 2 by cable body steel wire, be built in the core pipe at cable body center, slip casting connector 8, plug 7 are constituted.
The external diameter of cable body 2 is Φ 22mm～Φ 40mm.The built-in core pipe in cable body center includes afterbody rigid core pipe 6, flexible core pipe 9 and head rigid core pipe 10.Afterbody rigid core pipe 6 is arranged in the bottom of the afterbody of cable body 2, i.e. figure, corresponding with the position of ground tackle 5.
The shell anchor head 1 that rises is arranged on the front portion of cable body 2, i.e. top in figure.The built-in head rigid core pipe 10 in the position corresponding with the shell anchor head 1 that rises at the center of cable body 2 front portion.
Flexible core pipe 9 is positioned at the middle part of cable body, and its front end is connected with head rigid core pipe 10, and its rear end is connected with afterbody rigid core pipe 6.Head rigid core pipe 10, flexible core pipe 9, afterbody rigid core pipe 6 are linked in sequence successively, and are connected with the slip casting connector 8 of anchor cable afterbody, constitute slip casting passage.
Stop grouting plug 3 is positioned on the cable body 2 at anchor cable rear portion, is positioned at the position in aperture and hole thereof.
When afterbody rigid core pipe 6 makes ground tackle lock, cable body diameter does not shrink；Head rigid core pipe 10 make to rise shell anchor head 1 when anchoring cable body diameter do not shrink；Flexible core pipe can make anchor cable bending or dish circle be readily transported and install.
Cable body steel wire one end of cable body 2 and head rigid core pipe 10 consolidate, and its other end is consolidated with afterbody rigid core pipe 6 and slip casting connector.The tail end of slip casting connector 8 is provided with plug 7.
Cable body adopts steel wire to be twisted.Steel wire and high-strength helix rib steel wire or bright steel wire.The large aperture grouting cable anchor of various outer diameter according to field requirement, can be processed.Gauge of wire is between Φ 4mm～Φ 9mm, and steel wire quantity is between 8～30.
Rise the structure of shell anchor head 1 and component thereof shown in Fig. 2～5.Risen by intermediate plate 21, taper plug 22, the shell 23 that rises, spring leaf 24 and round section joint ring 25 of the shell anchor head 1 that rises on cable body top is constituted.Intermediate plate 21 is identical with the intermediate plate of ground tackle 5；Shell 23 outer surface that rises is zigzag, it is simple to embedding rock during spreading, its inner surface is arc, and the plug 22 that rises with taper contacts；The distance of spring leaf 24 two ends spreading, more than bore diameter, can be stuck on the wall of a borehole when anchor cable is installed.
Also illustrate that the structure of stop grouting plug 3 in FIG.Stop grouting plug 3 is made up of locking clip 14, rubber ring 13, baffle ring 12 and extruded tube 11；These four components are sequentially sleeved on cable body 2 from A-P.Locking clip 14 lock ring on cable body 2, maintain static；The lower end of extruded tube 11 withstands on above pallet 4；Under the pushing of pallet 4, extruded tube 11, baffle ring 12 along cable body forward slip, can extrude the rubber ring 13 between cable body 2 and hole wall.When extruded tube 11 extrudes rubber ring 13, rubber ring 13 deforms, and tamps the gap between cable body and borehole wall, forms sealing of hole in hole, it is prevented that serosity outflows.
Stop grouting plug may be used without cone rubber or flexible plastic stop grouting plug carries out sealing of hole.Rubber ring internal diameter is slightly larger than the external diameter of cable body, and external diameter is slightly less than bore diameter, makes of soft elastomeric material, such as rubber, flexible plastic etc..
Extruded tube 11 is rigid material, and material can be steel pipe or PVC engineering plastics pipe etc.；Its effect is when to anchor cable Shi Hanzhang, extrudes rubber ring, makes rubber ring compressive deformation, seals boring.
The shell anchor head that rises that large aperture grouting cable anchor adopts can also take other form:
Fig. 6 illustrates the another kind of structure of the shell anchor head that rises.It by inner sleeve 26, rise by shell 23 and spring leaf 24 is constituted.Its shell 23 that rises, spring leaf 24 and above-mentioned the identical of shell anchor head 1 of rising.Inner sleeve 26 top is that cylindrical shape, bottom are cone shape, have axle center hole, directly nested by its axle center hole and be squeezed on cable body 2.The taper seat of inner sleeve 26 coincide with the arc-shaped inner surface of the shell 23 that rises, contacts.Cable body 2 drives inner sleeve 26 to move down, and will make the shell 23 spreading embedding hole wall rock that rises.
Fig. 7 illustrates the third structure of the shell anchor head that rises.It by inner sleeve 26, Extruding spring 27, rise by shell 23 and spring leaf 24 is constituted.Its inner sleeve 26, the shell 23 that rises, spring leaf 24 are identical with the shell anchor head that rises shown in Fig. 6.The difference is that, in the axle center hole of inner sleeve 26, set up Extruding spring 27, that is between inner sleeve 26 and cable body 2, increase an Extruding spring 27.Inner sleeve 26 is squeezed on cable body 2 by Extruding spring 27, it is possible to be fixedly arranged at more securely on cable body 2.
Application example:
Gansu one metal mine buries deeply, press height, roadway surrounding rock hard and broken, grouting cable anchor of need to constructing is reinforced.It is designed with diameter Ф 22mm, long 8000mm expansion shell type hollow grouting cable anchor.Using drill jumbo perforating, adopt the drill bit construction of diameter 54mm, punch degree of depth 7700mm.
Anchor cable steel wire: select the helix rib steel wire 8 of Ф 6mm.Rigid core pipe: adopt Ф 10mm × 2, long 800mm；Soft core pipe: adopt long 6400mm.Stop grouting plug: locking clip selects steel pipe manufacturing, external diameter Ф 32mm, internal diameter 26mm, length 30mm；Rubber ring selects external diameter Ф 51mm, internal diameter Ф 24mm, length 200mm；Baffle ring selects plain washer, external diameter Ф 44mm, internal diameter Ф 24mm, thickness 3mm；Extruded tube selects steel pipe or duroplasts processing, external diameter Ф 32mm, internal diameter Ф 24mm, length 300mm.Rise shell anchor head: adopts Anchor Cable Anchorage form, draws with rising jack intermediate plate and taper to be risen and fills in and anchor cable jam-packed, installs spring leaf and the shell that rises.Rise shell by taper do not rise plug tension before outside dimension be Ф 52～54mm, after stress spreading, outside dimension is Ф 55～63mm.
