Specific implementation mode
A kind of preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, the droplet-shaped saddle end seal is arranged in two ends of saddle 80 comprising pressure
Tight plate 10 turns to sealing mechanism 20, coupling tube 30, extension 50 and cord clip 60, the pressure plate 10 and steering sealing mechanism 20
Positioned at the outside of saddle end droplet-shaped partition board 81, wherein pressure plate 10 is close to droplet-shaped partition board 81, and in saddle end
Wall shape is adapted, and is turned to sealing mechanism 20 and is close to 30 end of coupling tube, and is adapted with saddle inner wall of end shape, described
Coupling tube 30 is fixedly connected with saddle end by bolt and gasket 70.On the pressure plate 10 and steering sealing mechanism 20
The through-hole 23 for penetrating steel strand wires is offered, extension 50 is arranged in the end of coupling tube 30, and cord clip 60 is arranged in the extension
In pipe, for being gripped to steel strand wires, steel strand wires 90 sequentially pass through extension, coupling tube, turn to sealing mechanism and pressure
After tight plate, entered in saddle duct from the droplet-shaped partition board of saddle end.
It is formed with for the close of filling with sealant between the pressure plate 10 and steering sealing mechanism 20 and 80 end of saddle
Chamber 40 is sealed, fluid sealant plays the role of waterproof and anticorrosion, which uses colloidal resin, colloidal resin tool to be a bit sticky,
Its will not be because of traffic load impact or wind battle array act on caused by steel strand wires vibrations and along steel strand wires PE outer jackets surface overflow,
Compared with the mode of traditional anti-corrosion grease encapsulation process, using colloidal resin encapsulation process, there are significant performance advantages.This reality
It applies the colloidal resin used in example for FASTEN1000A to expect, is widely used in the anti-of bridge stay cable prestress system anchoring section
Rotten sealing process, durability have obtained the inspection of many projects under construction with reliability.
Traditional saddle uses the lined rubber pad locator of steel structure casing, locator steel structure casing whole body setting number
A metal voussoir adjusts the shank of bolt of damper end face when use, so that metal voussoir is stretched out and be against transition inside pipe wall, to protect
Card drag-line steel strand wires are in shaft core position, have the function that positioning.Due to Conventional positioners steel structure casing, metal voussoir and mistake
It crosses between pipe that there are prodigious gaps, the convection current up and down of steam in drag-line HDPE outer tubes can not be prevented, the present invention is to positioning
Device mechanism is further optimized：
It is provided with the damping locator 31 for positioning steel strand wires in the coupling tube 30 and determines for sealing the damping
The rubber locator 32 of position device, the rubber locator are adapted with the inner wall shape of coupling tube 30, and can fill damping positioning
Gap between device and coupling tube, improved locator scheme not only act as the effect to drag-line correction positioning, and can
The upward circulation for obstructing steam in drag-line HDPE outer tubes, further improves the sealing effect of waterproof and anticorrosion.
As shown in Fig. 2, the steering sealing mechanism 20 includes a pair of of 21, rubber mat plates 22 of sealing plate and multiple transition
Plate 26, wherein sealing plate are arranged 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 the channel 27 by single steel strand between adjacent transition plate.Institute
The shape for stating sealing plate, rubber mat plate and rebound is adapted with the inner wall shape of 80 end of saddle.
Before the steering installation of sealing mechanism 20 is fixed, using welding, equipment will be tightened, positioning bolt is fixed on steering sealer
On sealing plate on the inside of structure.It, first will be in the rebound push-in droplet-shaped saddle of sealing plate, inside when installation turns to sealing mechanism
Portion's design position is sealed processing using preparing neutral structure silicone adhesive for the gap of rebound and saddle steel plate；Then it fixes
Rubber mat plate, shape use trapezoidal cross-section, thoroughly wedging and can block saddle steel member inner wall；Later, outside is installed
Rebound, using encapsulation process mode identical with the rebound of inside；The finally sealing plate in installation outside, 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 exhaust pipe that is provided with the injected rubber hose for injecting fluid sealant and is arranged with the injected rubber hose skew symmetry, injected rubber hose and exhaust pipe
Belong to the prior art, therefore is not shown in figure.The present embodiment exists, and injected rubber hose is located at the lower end of two sealing plates, passes through injecting glue
Pipe completely cuts off air and other media and steel to the gap pressure injection colloidal resin of end part seal plate and saddle both sides droplet-shaped partition room
The pressure injection mode of the contact of twisted wire, colloidal resin is as follows：
First using lower section injected rubber hose as hole for injecting glue, top exhaust pipe is as plastic hole, using pneumatic mortar machine by colloidal resin
It is pressed into saddle end plate and turns to the gap between sealing mechanism end part seal plate, until the gluey tree of exhaust pipe outflow above sealing plate
After removing the glue-injection machine on injected rubber hose, injected rubber hose and exhaust pipe are blocked using bolt for fat.
After pressure injection colloidal resin, by tightening the positioning bolt turned on sealing mechanism, due to the effect of rubber mat plate, energy
Enough block the gap between rebound duct and steel strand wires, it is ensured that colloidal resin will not be oozed out from gap.
Turning to the rubber mat plate 22 that sealing mechanism uses has good extension property, when screwed in place bolt, rubber pad
Plate compressive deformation, can will seal the gap between steering mechanism duct and steel strand wires, water-drop-shaped saddle steel member inner wall with it is close
The gap of envelope transfer, which blocks, tamps, to prevent colloidal resin from being oozed out from gap.
It turns to sealing mechanism and uses high intensity positioning bolt, disclosure satisfy that the factors such as traffic load, dead load to bolt
The requirement of intensity.
Above-mentioned sealing corrosion treatment measures can ensure to turn to the gap of sealing mechanism and droplet-shaped saddle steel member inner wall
The occurrence of thoroughly being blocked, preventing bridge operation stage colloidal resin from being oozed out from gap.
Rubber mat plate 22 selects neoprene, tensile strength 10-30Mpa to break in pressure plate 10 and steering sealing mechanism
Elongation 250% is split, 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.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
It encloses and is defined, under the premise of not departing from design spirit of the present invention, technical side of the those of ordinary skill in the art to the present invention
The various modifications and improvement that case is made should all be fallen into the protection domain of claims of the present invention determination.
