Detailed description of the invention
Below in conjunction with the accompanying drawings a kind of preferred implementation of the present invention is described in detail.
The saddle end seal described in as it is shown in figure 1, with double localizer is arranged in two ends of saddle 80,
It includes pressure strip 10, turns to sealing mechanism 20, transition conduit 30, extension 50 and cord clip 60, described pressure strip 10 and turn to close
Sealing mechanism 20 is positioned 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 suitable, turn to sealing mechanism 20 to be close to transition conduit 30 end, and with saddle inner wall of end shape phase
Adaptation, described transition conduit 30 is fixed with saddle end be connected by bolt and sealing gasket 70.Described pressure strip 10 and turn to sealing
All offering the through hole 23 for penetrating steel strand wires in mechanism 20, extension 50 is arranged on the end of transition conduit 30, and cord clip 60 sets
Put in this extension, for steel strand wires are gripped, steel strand wires 90 sequentially pass through extension, transition conduit, turn to close
After sealing mechanism and pressure strip, enter in saddle duct from the droplet-shaped dividing plate of saddle end.
Described pressure strip 10 and turning to is formed for filling with sealant between sealing mechanism 20 and saddle 80 end close
Envelope chamber 70, fluid sealant plays the effect of water-tight corrosion-proof, and this fluid sealant uses colloidal resin, colloidal resin tool to be a bit sticky,
It will not overflow along steel strand wires PE outer jacket surface because of the steel strand wires vibrations that the impact of traffic load or wind battle array effect cause,
Compared with the mode of tradition anticorrosion oils and fats encapsulation process, colloidal resin encapsulation process is used to there is significant performance advantage.This reality
Executing the colloidal resin used in example is FASTEN1000A material, is widely used in the anti-of bridge stay cable prestress system anchoring section
Rotten sealing process, its durability and reliability have obtained the inspection of many projects under construction.
Tradition saddle uses steel structure casing lined rubber pad localizer, the localizer steel structure casing whole body to arrange number
Individual metal voussoir, regulates the shank of bolt of amortisseur end face, makes metal voussoir stretch out and be against transition conduit inwall, thus protecting during use
Card drag-line steel strand wires are in shaft core position, reach the effect of location.Due to Conventional positioners steel structure casing, metal voussoir and mistake
Crossing and there is the biggest space between pipe, can not stop the convection current up and down of steam in drag-line HDPE trocar sheath, the present invention is to location
Device mechanism is further optimized:
The damping localizer 31 for positioning steel strand wires it is provided with and for sealing this damping localizer in described transition conduit 30
Rubber localizer 32, this rubber localizer is suitable with the inner wall shape of transition conduit 30, and can fill damping localizer with
Gap between transition conduit, the localizer scheme after improvement not only acts as the effect to drag-line correction location, and can intercept
In drag-line HDPE trocar sheath, the upwards circulation of steam, further increases the sealing effectiveness of water-tight corrosion-proof.
Sealing mechanism 20 is turned to include 21, rubber mat plate 22 of a pair sealing plate and multiple transition described in as in figure 2 it is shown,
Plate 26, wherein sealing plate is set in parallel in the both sides of rubber mat plate, and described rebound 26 connects rubber mat plate and two for vertical
Side sealing plate, multiple rebounds are arranged in parallel, and are formed 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 all suitable with the inner wall shape of saddle 80 end.
Before turning to sealing mechanism 20 installation fixing, facility will be tightened, bolt is fixed on and turns to sealer to use welding
On sealing plate inside structure.When installation turns to sealing mechanism, first by sealing plate, the rebound of inner side pushes in droplet-shaped saddle
Portion's design attitude, uses preparing neutral structure silicone adhesive to carry out encapsulation process for the gap of rebound Yu saddle steel plate；Then fix
Rubber mat plate, its profile uses trapezoidal cross-section, it is possible to thorough wedging also blocks saddle steel beam column inwall；Afterwards, outside installation
Rebound, uses the encapsulation process mode identical with the rebound of inner side；The sealing plate in outside, screwed in place spiral shell are finally installed
Bolt.
The through hole for penetrating single steel strand, described sealing plate is all offered on described sealing plate 21 and rubber mat plate 22
On be provided with the injected rubber hose for injecting fluid sealant and with this injected rubber hose skew symmetry arrange exhaustor, injected rubber hose and exhaustor
Belong to prior art, therefore not shown in figure.The present embodiment exists, injected rubber hose be positioned at two sealing plates bottom, pass through 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 is as follows:
First using lower section injected rubber hose as hole for injecting glue, top exhaustor, as plastic hole, uses pneumatic mortar machine to be pressed into by colloidal resin
Saddle end plate and turn to the space between sealing mechanism end seal plate, until the exhaustor above sealing plate flows out colloidal resin,
After removing the glue-injection machine on injected rubber hose, use bolt closure injected rubber hose and exhaustor.
After pressure injection colloidal resin, by tightening the bolt turned on sealing mechanism, due to the effect of rubber mat plate, energy
Enough spaces between closure rebound duct and steel strand wires, it is ensured that colloidal resin will not ooze out from space.
The rubber mat plate 22 turning to sealing mechanism to use has good extension property, during screwed in place bolt, and rubber blanket
Plate compression, it is possible to by the space sealed between steering mechanism duct and steel strand wires, water-drop-shaped saddle steel beam column inwall with close
The space closure of envelope transfer is tamped, thus prevents colloidal resin from oozing out from space.
Sealing mechanism is turned to use high intensity bolt, it is possible to meet the factor such as traffic load, dead load to bolt
The requirement of intensity.
Above-mentioned sealing corrosion treatment measures ensure that the gap turning to sealing mechanism with droplet-shaped saddle steel beam column inwall
Thoroughly blocked, prevent bridge operation stage colloidal resin from oozing out the generation of situation from gap.
Pressure strip 10 and turn to rubber mat plate 22 in sealing mechanism to select neoprene, its tensile strength 10-30Mpa, disconnected
Splitting percentage elongation 250%, tearing strength 20-80KN, mooney viscosity 40-120ML1001+4, damped coefficient 0.15-0.30, remaining refers to
Mark all meets the requirement of GB/T14647-2008 " neoprene divinyl rubber CR121, CR122 ".
The above embodiment is only to be described the preferred embodiment of the present invention, the not model to the present invention
Enclose and be defined, on the premise of designing spirit without departing from the present invention, the those of ordinary skill in the art technical side to the present invention
Various deformation that case is made and improvement, all should fall in the protection domain that claims of the present invention determines.
