Description
Technical field
This utility model is related to a kind of modular construction of bridge and in particular to a kind of bridge stay cable anchored end is anti-corrosion anti-
The termination device of water, is mainly used in the end seal of suspension cable anchored end port, to prevent the suspension cable quilt in bridge stay cable sleeve pipe
Water or other debris enter and produce corrosion, belong to bridge parts manufacture technology field；But can also be used for the closure of other pipelines.
Background technology
The oblique pull cable system of modern Longspan Bridge is the major bearing structures of cable-stayed bridge.Suspension cable is due to residing special
Use environment and condition, corrosion phenomenon is more serious.According to the actual inspection to suspension cable use and accident condition, suspension cable system
The protection of system was lost efficacy and was mostly occurred in end, and reason is because structure limits inconvenient examination and maintenance after this position is installed.Therefore,
The emphasis that the anchor end protection of oblique pull cable system is regarded as protecting is paid close attention to and is paid attention to.
The upper anchor end of stay cable of cable-stayed bridge system is anchored in king-tower, end of casting anchor be anchored in stiff girder (on).Manufacturing
During suspension cable, typically all necessary safeguard procedures are taken to cable body and anchor device structure aspect.The protection of suspension cable anchor end is mainly
Scene protection, it is important that the position such as combination of tower end and beam-ends suspension cable exit, anchorage and anchor slab.Suspension cable anchor end is prevented
The basis of shield is the technical matters combination application such as structure, filling, sealing, application, for use under different structure varying environment
Different combination protection forms taken by cable-stayed bridge, feature be guy anchor end protected section implement respectively structural defence and sealing,
Filling and paint spraying protection.
Take following measures that the anchor end of oblique pull cable system is protected before becoming bridge operation：
(1) exsertion part covering rustless steel protective cover sealing suspension cable anchor end being combined with anchor structure, prevents this portion
Position is contacted with pollutant.
(2) oblique pull cable guide pipe (anchor tube) interior filled polyurethane expanded material sealing, stops the entrance of moisture and pollutant.
(3) add rustless steel rain cover at beam-ends suspension cable conduit outlet, intercept water inlet, beautify the outer of this section simultaneously
See effect.
(4) suspension cable shortcut face section integral coating stainless steel protective cover.
Due to external for a long time, easy hydrops in suspension cable anchor tube (pre-buried casing pipe), enter debris, cause stay cable end structure
, there is corrosion and damage, the service life of impact suspension cable in pollution.It is filled in oblique pull using closure polyurethane foam in recent years
In the gap of rope and anchor tube, prevent moisture and pollutant from entering in suspension cable casing pipe.Specific practice is the material with better performances
Material, carries out foam filled in conduit (anchor tube), then carries out the sealing protection of necessary port and processes.
Mode the more commonly used at present is polyurethane foam material filling mode waterproof, due to steel cable bridge out of doors with
Shi Douhui produces according to the impact of extraneous natural conditions and swings so that forming crack between expanded material and cable wire and conduit, for a long time
Go down and just lose waterproof effect, in addition cannot judge whether anchor end is corroded in row maintenance repair anchoring into suspension cable, only
Have fully erased expanded material could overhaul, so also very trouble is unfavorable for Construction and Maintenance, therefore necessary to this in addition
Improve.
By patent retrieval and do not find there be the patent literature constructed with this utility model, have with this utility model
The patent of certain relation mainly has following：
1st, Patent No. CN201520845168.2, the reality of entitled " a kind of anchor end preventer of bridge stay cable "
With new patent, which disclose a kind of anchor end preventer of bridge stay cable, belong to long strands field, solve
Suspension cable waterproof sealing problem.Including suspension cable, outside described suspension cable, it is provided with anchor tube, between described anchor tube and described suspension cable
It is filled with polyurethane foam, above described suspension cable, is additionally provided with rain cover, also fill between described rain cover and described suspension cable
There is polyurethane foam, the top of the upper end of described anchor tube and described rain cover is equal to be provided with sealing block and described suspension cable between, institute
State and between rain cover lower end and the upper end of described anchor tube, be provided with fluid sealant, between the upper end of described rain cover and described suspension cable
It is provided with fluid sealant.
2nd, Patent No. CN201320051487.7, the practicality of entitled " a kind of stay cable internal damping damping unit "
New patent, which discloses a kind of stay cable internal damping damping unit, and described device includes a plantation rubber cylinder, institute
State and internal expanding groove is provided with cylinder, in described internal expanding groove, be provided with inner bulging device, described cylinder is contained within described oblique
The accommodation space of drag-line it is characterised in that：Described inner bulging device quantity at least four, and be in be arranged circumferentially.
3rd, Patent No. CN201320294709.8, entitled " the adhesive tape sealing dress for long span stayed-cable bridge drag-line
Put " patent of invention, which disclose a kind of adhesive tape sealing device for long span stayed-cable bridge drag-line, including transition rubber
Cushion rubber, is characterized in that：Also include adhesive tape, the internal diameter of the external diameter of transition rubber circle and drag-line cable guide pipe is equal, transition rubber circle
Internal diameter and drag-line cable body external diameter equal；Detent at least one, transition rubber are had on the medial wall of transition rubber circle
One outside fix groove had on the lateral wall of cushion rubber, interior detent place plane and outside fix groove place plane are all and mistake
The bottom surface crossing rubber ring is parallel, and two adhesive tapes are embedded in the inner and outer detent of interior detent respectively.
Although so the structure that these patents above-mentioned are directed to bridge stay cable port is improved, and it is concrete to propose some
Improved technology scheme, but all not proposing how to change in bridge stay cable port sealing water-tight corrosion-proof noted earlier is deposited
Problem, therefore foregoing problem yet suffers from, and the sealing water-tight corrosion-proof of bridge stay cable port is easily because oblique pull
Rope swings and leads to water-tight corrosion-proof to lose efficacy, and cannot judge in maintenance repair that the problem whether anchor end is corroded yet suffers from, and still has
Treat to be improved further.
