JT/T771-2009《Non-bending steel cable suspension cable technical conditions》Require in professional standard after suspension cable installation tensioning terminates,
The exposed steel strand wires in anchorage zone and suspension cable end of suspension cable should irrigate anti-corrosion grease, to carry out to the partial denudation steel strand wires
Preserving and sealing process.Anti-corrosion filling inside guy of twisted steel cable anchorage is one critical process in drag-line installation process, its filling
The anti-corrosive properties of material of reliability will be one of the key factor for determining steel strand stay cable bulk life time.Grease, flexible tree
The material such as fat and paraffin can be used in the anti-corrosion filling inside steel strand stay cable anchorage.
At home in the evolution of steel strand stay cable technology, the limitation and domestic suspension cable selected because of anti-corrosion material is advised
Relatively lagging behind for model, in conventional steel strand stay cable design and installation process, lubricates frequently with unbonded tendon special anti-corrosion
As packing material in anchorage.Though this anti-corrosion grease have preferable antisepsis, because its Stencil oil-dividing amount it is larger, and
The oil separated out from anti-corrosion grease has very strong permeability, so as to cause in use, anti-corrosion lubrication often occurs
The phenomenon of fat seepage.Because currently the majority bridge all adopts form construction technology, the anti-corrosion grease for leaking out is from built-in pipe
Mouth flows out can cause tower wall to pollute, and greatly affect the overall appearance of bridge, can also cause matter of the citizen to bridge construction quality
Doubt, to society harmful effect is brought, it is often more important that therefore the steel strand wires of PE sections are divested inside anchorage can cannot get effective
, there is certain durability hidden danger in protection.
Utility model content
The utility model provides a kind of with multi-sealed, the anti-corrosion anchor device of anti-corrosion material seepage is prevented, with good
Antiseptic property and anti-fatigue performance.
To solve above-mentioned technical problem, the utility model is adopted the following technical scheme that：
A kind of anti-corrosion anchor device, it is described including for clamping the anchor plate and anchor slab for anchoring single rope muscle of Suo Shu
Anchor slab is provided with inner sleeve and sealing gasket for sealing rope muscle near the side of anchor plate, and the opposite side of the anchor slab is provided with
Protective cover, is formed with the cavity for filling anticorrosive materials in the protective cover, anchoring between the anchor slab and rope muscle has intermediate plate, the folder
The front end of piece is provided with damping.
Further, the damping includes the bushing and compression spring for extruding the intermediate plate front end, Yi Jiyong
In the locking pressing plate for compressing compression spring, the bushing, compression spring and locking pressing plate are set on single rope muscle.
Further, about collar for clamping Suo Shu and about beam ring are provided with the anchor plate, wherein constraining ring set
Suo Shushang is located at, constraint is placed between confinement ring and anchor plate.
Preferably, the side of the about collar and about beam ring is provided with sealing drum.
Preferably, inlet and flow export are offered respectively on the protective cover, the inlet and flow export use spiral shell
Bolt is sealed.
From above technical scheme, the utility model to the exposed steel in the anchorage zone of suspension cable and suspension cable end by twisting
Anti-corrosion material is irrigated at line, and carries out multi-sealed by inner sleeve, about sealing gasket, collar and about beam ring, prevent seepage；
Increase damping, can effectively reduce the harm produced by cable body vibration.

Specific embodiment
A kind of preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As shown in figure 1, the anti-corrosion anchor device includes anchor plate 1 and the anchor slab 2 being bolted together, wherein anchor plate is used
In clamping Suo Shu 92, anchor slab anchors single rope muscle 91 by intermediate plate 7.
Suo Shu is clamped by about collar 41 and confinement ring 42 in the anchor plate 1, wherein confinement ring is set in Suo Shushang, about
Collar is placed between confinement ring and anchor plate, and the side of about collar and about beam ring is provided with sealing drum 43, about collar, confinement ring and
Sealing drum constitutes first sealing.
The anchor slab 2 is being provided with inner sleeve 3 and sealing gasket 4 with the junction of rope muscle 91, constitutes second sealing.
The anchor slab 2 is provided with protective cover 5 in rope muscle end exposed section, is formed with the protective cover for filling anticorrosive materials
Cavity 6, offer inlet 51 and flow export 52 on the protective cover respectively, the inlet and flow export are entered using bolt 53
Row sealing, protective cover constitutes three seals.
As shown in Fig. 2 the damping 8 is arranged on the front end of intermediate plate 7, prevent anchorage from shaking for compressing intermediate plate, its
