With the outside for turning to sealing mechanism 20 and being located at saddle end droplet-shaped dividing plate 81, wherein pressure strip 10 is tight with droplet-shaped dividing plate 81
Patch, and is adapted with saddle inner wall of end shape, turns to sealing mechanism 20 and is close to the end of transition conduit 30, and with saddle end in
Wall shape is adapted, and the transition conduit 30 is fixedly connected with saddle end by bolt and sealing gasket 70.The He of the pressure strip 10
The through hole 23 offered on sealing mechanism 20 for penetrating steel strand wires is turned to, extension 50 is arranged on the end of transition conduit 30,
Cord clip 60 is arranged in the extension, and for gripping to steel strand wires, steel strand wires 90 sequentially pass through extension, transition
After pipe, steering sealing mechanism and pressure strip, enter in saddle duct from the droplet-shaped dividing plate of saddle end.
It is formed with for the close of filling with sealant between the pressure strip 10 and steering sealing mechanism 20 and the end of saddle 80
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 grease encapsulation process, there is significant performance advantage using colloidal resin encapsulation process.This reality
The colloidal resin adopted in example is applied for FASTEN1000A material, the anti-of bridge stay cable prestress system anchoring section is widely used in
Rotten sealing process, its durability has obtained the inspection of many projects under construction with reliability.
Traditional saddle adopts the lined rubber pad locator of steel structure casing, the locator steel structure casing whole body to arrange number
Individual metal voussoir, adjusts the shank of bolt of damper end face when using, stretch out metal voussoir and be against transition inside pipe wall, so as to protect
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 between pipe and there is very big space, the convection current up and down of steam in drag-line HDPE outer tubes, the utility model pair can not be prevented
Positioner mechanisms are further optimized：
The damping locator 31 for positioning steel strand wires is provided with the transition conduit 30 and is determined for sealing the damping
The rubber locator 32 of position device, the rubber locator is adapted with the inner wall shape of transition conduit 30, and can fill damping positioning
Gap between device and transition conduit, the locator scheme after improvement not only acts as the effect of positioning of rectifying a deviation to drag-line, and can
The circulation upwards of steam in drag-line HDPE outer tubes 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 between adjacent transition plate for by the passage 27 of single steel strand.Institute
The profile for stating sealing plate, rubber mat plate and rebound is adapted with the inner wall shape of the end of saddle 80.
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.When steering sealing mechanism is installed, the rebound of sealing plate, inner side is pushed in droplet-shaped saddle first
Portion's design attitude, using preparing neutral structure silicone adhesive for the gap of rebound and saddle steel plate carries out encapsulation process；Then fix
Rubber mat plate, its profile adopts trapezoidal cross-section, thoroughly wedging and can block saddle steel beam column inwall；Afterwards, on the outside of installation
Rebound, using the rebound identical encapsulation process mode with inner side；Sealing plate on the outside of finally installing, screwed in place spiral shell
Bolt.
The through hole for penetrating single steel strand, the sealing plate are offered on the sealing plate 21 and rubber mat plate 22
On the blast pipe that is provided with injected rubber hose for injecting fluid sealant and arranges with the injected rubber hose skew symmetry, injected rubber hose and blast pipe

Pipe is to the space pressure injection colloidal resin between end part 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 blast pipe as plastic hole, using pneumatic mortar machine by colloidal resin
Space between press-in saddle end plate and steering sealing mechanism end part seal plate, until the blast pipe above sealing plate flows out gluey tree
Fat, after removing the glue-injection machine on injected rubber hose, using bolt injected rubber hose and blast pipe is blocked.
After pressure injection colloidal resin, by tightening the bolt turned on sealing mechanism, due to the effect of rubber mat plate, energy
Enough block the space between rebound duct and steel strand wires, it is ensured that colloidal resin will not ooze 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.
