Specific embodiment
Below in conjunction with the accompanying drawings a kind of preferred implementation of the present utility model is described in detail.
As shown in figure 1, the saddle end seal with double localizers is arranged in two ends of saddle 80,
Which includes pressure strip 10, turns to sealing mechanism 20, transition conduit 30, extension 50 and cord clip 60, and the pressure strip 10 and steering are close
Sealing mechanism 20 is located at the outside of saddle end droplet-shaped dividing plate 81, and wherein pressure strip 10 is close to droplet-shaped dividing plate 81, and and saddle
Seat inner wall of end shape be adapted, turn to sealing mechanism 20 be close to 30 end of transition conduit, and with saddle inner wall of end shape phase
Adaptation, the transition conduit 30 passes through bolt with saddle end and sealing gasket 70 is fixedly connected.The pressure strip 10 and steering sealing
Offer in mechanism 20 for penetrating the through hole 23 of steel strand wires, extension 50 is arranged on the end of transition conduit 30, and cord clip 60 sets
Put in the extension, for gripping to steel strand wires, steel strand wires 90 sequentially pass through extension, transition conduit, turn to it is close
After sealing mechanism and pressure strip, enter in saddle duct from the droplet-shaped dividing plate of saddle end.
The pressure strip 10 and steering sealing mechanism 20 and saddle are formed with for the close of filling with sealant between 80 end
Envelope chamber 70, fluid sealant plays a part of water-tight corrosion-proof, and the fluid sealant adopts colloidal resin, colloidal resin tool to be a bit sticky,
Its steel strand wires that will not be caused because of the impact of traffic load or the effect of wind battle array shakes and overflows along steel strand wires PE outer jackets surface,
Compared with the mode of traditional anti-corrosion oils and fatss encapsulation process, there is significant performance advantage using colloidal resin encapsulation process.This reality
The colloidal resin adopted in applying example is FASTEN1000A material, is widely used in the anti-of bridge stay cable prestress system anchoring section
Rotten sealing process, its durability have obtained the inspection of many projects under construction with reliability.
Traditional saddle adopts the lined rubber pad localizer of steel structure casing, the localizer steel structure casing whole body to arrange number
Individual metal voussoir, adjusts the shank of bolt of amortisseur end face, makes metal voussoir stretch out and be against transition inside pipe wall, so as to protect during use
Card drag-line steel strand wires are in shaft core position, reach the effect of positioning.Due to Conventional positioners steel structure casing, metal voussoir and mistake
Cross and between pipe, there is very big space, the convection current up and down of steam in drag-line HDPE trocar sheaths, this utility model pair can not be prevented
Positioner mechanisms are further optimized：
The damping localizer 31 for positioning steel strand wires is provided with the transition conduit 30 and is determined for sealing the damping
The rubber localizer 32 of position device, the rubber localizer are adapted with the inner wall shape of transition conduit 30, and can fill damping positioning
Gap between device and transition conduit, the localizer scheme after improvement not only act as the effect of positioning of rectifying a deviation to drag-line, and can
The circulation upwards of steam in drag-line HDPE trocar sheaths is intercepted, the sealing effectiveness of water-tight corrosion-proof is further increased.
As shown in Fig. 2 the steering sealing mechanism 20 includes a pair of sealing plates, 21, rubber mat plate 22 and multiple transition
Plate 26, wherein sealing plate are set in parallel in the both sides of rubber mat plate, and the rebound 26 is used for vertical connection rubber mat plate and two
Side sealing plate, multiple rebounds are arranged in parallel, and are formed with for by the passage 27 of single steel strand between adjacent transition plate.Institute
State sealing plate, the profile of rubber mat plate and rebound is adapted with the inner wall shape of 80 end of saddle.
Steering sealing mechanism 20 is installed before fixing, and using welding, equipment will be tightened, bolt is fixed on steering sealer
On sealing plate on the inside of structure.Install when turning to sealing mechanism, first by sealing plate, the rebound of inner side pushed in droplet-shaped saddle
Portion's design attitude, the gap using preparing neutral structure silicone adhesive for rebound with saddle steel plate carry out encapsulation process；Then fix
Rubber mat plate, its profile adopt trapezoidal cross-section, thoroughly wedging can block saddle steel beam column inwall；Afterwards, outside is installed
Rebound, using the rebound identical encapsulation process mode with inner side；The sealing plate in outside, screwed in place spiral shell are finally installed
Bolt.
Offer on the sealing plate 21 and rubber mat plate 22 for penetrating the through hole of single steel strand, the sealing plate
On the exhaustor that is provided with injected rubber hose for injecting fluid sealant and arranges with the injected rubber hose skew symmetry, injected rubber hose and exhaustor
Belong to prior art, therefore not shown in figure.The present embodiment exists, injected rubber hose be located at two sealing plates bottom, by injecting glue
Pipe is to the space pressure injection colloidal resin between end seal plate and saddle both sides droplet-shaped dividing plate, isolation air and other media and steel
The contact of twisted wire, the pressure injection mode of colloidal resin are as follows：
First using lower section injected rubber hose as hole for injecting glue, top exhaustor as plastic hole, using pneumatic mortar machine by colloidal resin
Space between press-in saddle end plate and steering sealing mechanism end seal plate, until the exhaustor above sealing plate flows out gluey tree
Fat, after removing the glue-injection machine on injected rubber hose, blocks injected rubber hose and exhaustor using bolt.
After pressure injection colloidal resin, by tightening the bolt turned on sealing mechanism, due to the effect of rubber mat plate, energy
Space between rebound duct and steel strand wires is blocked enough, it is ensured that colloidal resin will not be oozed out from space.
The rubber mat plate 22 for turning to sealing mechanism employing has good extension property, during screwed in place bolt, rubber blanket
Plate compression, can by sealing steering mechanism duct and steel strand wires between space, water-drop-shaped saddle steel beam column inwall with it is close
The space closure of envelope transfer is tamped, so as to prevent colloidal resin from oozing out from space.
Turn to sealing mechanism and use high intensity bolt, disclosure satisfy that the factors such as traffic load, dead load to bolt
The requirement of intensity.
Above-mentioned sealing corrosion treatment measures ensure that the gap for turning to sealing mechanism and droplet-shaped saddle steel beam column inwall
Thoroughly blocked, the occurrence of prevent bridge operation stage colloidal resin from oozing out from gap.
In pressure strip 10 and steering sealing mechanism, rubber mat plate 22 selects neoprene, its tensile strength 10-30Mpa to break
Split percentage elongation 250%, tearing strength 20-80KN, mooney viscosity 40-120ML1001+4, damped coefficient 0.15-0.30, remaining refers to
Mark meets GB/T14647-2008《Neoprene divinyl rubber CR121, CR122》Requirement.
The above embodiment is only that preferred implementation of the present utility model is described, not to this practicality
New scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this
Various modifications and improvement that the technical scheme of utility model is made, all should fall into the guarantor that claims of the present utility model determine
In the range of shield.
