Abstract
The utility model relates to a sealed anchorage cable, which is composed of a drag cable and an anchorage device. The drag cable comprises a cable body, an embedded component, etc. The anchorage device comprises a clamping piece 11, an anchor plate 12, an anchor liner plate 4, a spiral bar 5, and protective covers 2. A steel strand 7 is tightly wedged with the anchor liner plate via the clamping piece and passes through the embedded part, and the cable body is formed by the anchor liner plate and a corrugated tube. The corrugated tube is a plastic corrugated tube. The tail of the anchor liner plate is sleeve with a plastic corrugated tube 6 and is sealed. The anchor heads at both ends are provided with the protective covers. The peripheries of protective covers are safely sealed at the contact point with the anchor liner plate, and the protective covers and the anchor liner plate are bound and connected by epoxy glue. The anchorage cable is in the fully sealed state, and no external moisture is penetrated in the sealed anchorage cable. The purpose that the steel strand is not broken because of corrosion is ensured, and the service life of the cable body can be lengthened.
Description
The utility model relates to the working anchor cable of a kind of prestress anchoraging.
Along with prestressing technique development; the posttension system has obtained extensive utilization, and grouting becomes the crucial barrier of presstressed reinforcing steel corrosion-resistant, as crucial one topping of corrosion-resistant; guaranteeing to play a part aspect the general safety of bridge very important, need guarantee its quality requirement.Traditional anchor cable is the non-tight formula, adopting metal bellows is the pore-forming pipeline, the back grouting machine that uses pours into concrete in the metal bellows of anchor cable by the anchor plate grout hole traditional grouting way for cable body stretch-draw finishes, the back infiltration if outer concrete block ftractures for some reason, the metal bellows of anchor cable is by corrosion, the grouting way of conventional grout construction makes to retain inevitably in the concrete in addition hole, the harmful water that is detained in the hole etc. will cause the steel strand fracture that is corroded, and rope generally can't be changed in the body, can cause workmanship like this to have a strong impact on.
It is the pore-forming pipeline that the purpose of this utility model is to provide a kind of employing plastic film capicitor, is difficult for being corroded, can guaranteeing grouting quality,, the sealed anchor cable that make it prolong cable body life-span anticorrosion to cable body better.
For reaching above-mentioned purpose; sealed anchor cable of the present utility model is by drag-line; ground tackle two parts are formed; drag-line partly comprises cable body; built-in fitting; ground tackle partly comprises intermediate plate; anchor slab; anchor plate; spiral bar and protective cover; steel strand pass built-in fitting-anchor plate by intermediate plate and anchor slab wedging; bellows forms cable body; be with existing anchor cable difference: described bellows is a plastic film capicitor; anchor plate afterbody and plastic film capicitor socket and sealing; the two ends anchor head partly is equipped with protective cover, and protective cover seals fully with the anchor plate contact position all around and constitutes hermetically sealed anchor cable with the epoxy glue bonding.
The sealed anchor cable of the utility model is that the plastic film capicitor that material is made is pore-forming pipeline, anchor plate afterbody and plastic film capicitor socket owing to the employing favorable sealing property, with corrosion resistant HDPE, anchor head partly is equipped with protective cover, protective cover seals fully with the anchor slab contact position all around and bonds with epoxy glue, make whole anchor cable be in whole sealing status, thereby, do not have outside steam and infiltrate, guarantee the steel strand fracture that is not corroded, prolonged the application life of cable body; Be and the matching used special-purpose anchor cable of vacuum grouting process.
Below, in conjunction with the accompanying drawings and embodiments, the technical characterictic of the sealed anchor cable of the utility model is further described.
Fig. 1: structural representation of the utility model sealed anchor cable and user mode reference diagram.
Embodiment:
As shown in Figure 1; the sealed anchor cable of the utility model; by drag-line; ground tackle two parts are formed; drag-line partly comprises cable body; built-in fitting etc.; ground tackle partly comprises intermediate plate 11; anchor slab 12; anchor plate 4; spiral bar 5 and protective cover 2; steel strand pass built-in fitting-anchor plate 4 by intermediate plate 11 and anchor slab 12 wedgings; bellows 6 forms cable body; described bellows 6 is a plastic film capicitor; anchor plate 4 afterbodys and plastic film capicitor 6 sockets and sealing; anchor head partly is equipped with protective cover 2; protective cover 2 seals fully with anchor plate 4 contact positions all around and bonds with epoxy glue; grout hole and steam vent are arranged on the protective cover 2; after anchor cable grouting finished, the protective cover planted agent filled with anticorrosion grease or cement mortar, and adopted bolt to add the form of sealing ring sealing with grout hole and steam vent sealing.
Described plastic film capicitor 6 pipe thicknesses are 5～10mm, diameter D=Φ 30～400mm.
