Description
Technical field
The present invention relates to a kind of guy of twisted steel cable component of bridge with sealing device, more particularly to one kind is using single close
The dragline anchorage of envelope.
Background technology
Dragline anchorage sealing device for bridge cable sealing, it is desirable to which water cannot enter under 3 meters high of hydraulic pressure effect
In anchorage, and can have good leakproofness and reliability during bridge operation.
The seal form of bridge steel strand wires dragline anchorage sealing device is divided into two kinds at present：
One kind is integral sealing, and integral sealing is to carry out integral sealing to penetrating all steel strand wires in anchorage annular seal space,
Every steel strand wires in annular seal space will cause whole without isolation, sealing unit seal failure between each other with being in an annular seal space
A anchorage corrosion protection failure；
Another kind be it is single independent sealed, it is single it is independent sealed be to penetrate the steel strand wires in anchorage annular seal space carry out it is single
It is independent sealed, anchorage annular seal space is separated into multiple independent sealing units, every steel strand wires separation arrangement is non-interference, no
Because of a sealing unit water inlet whole anchorage corrosion protection can be caused to fail, and anchor device structure is also compacter, smaller, institute
Single independent sealed device is employed with most of current bridge cable anchorage.
There are following shortcoming for existing single independent sealed dragline anchorage：
1. the seal of single sealing device is arranged between the lantern ring and isolated tube, seal is installed on isolated tube front end
In the lantern ring, i.e., isolated tube is sealed by the seal in the lantern ring of front end, is a kind of indirect sealing technique, and only with one layer
A sealing i.e. only seal（See Fig. 5）, sealing effect is bad, usually because annular seal space leakage water inlet causes whole anchorage corrosion protection
Failure；
2. seal is General Purpose Rubber material used by, poor flexibility, easy to aging, sealing performance is influenced, to bridge structure
Leave security risk.
The content of the invention
It is an object of the invention to provide a kind of dragline anchorage using single sealing, to overcome present in prior art
Above-mentioned deficiency, solves the problems such as existing single independent sealed dragline anchorage sealing performance is bad, anchorage is easily intake.
Adopted the technical scheme that to solve the above-mentioned technical problem present invention：A kind of dragline anchorage using single sealing,
Including protective cover, anchor slab, sealing drum, positioning plate, compression ring and single sealing device, after the protective cover is connected to anchor slab
End, the sealing drum are connected to the front end of anchor slab and form annular seal space, the list by the positioning plate and compression ring seal of front end
Root sealing device is positioned in sealing drum by positioning plate, compression ring, and each single protection steel in the annular seal space of sealing drum twists
Line by single sealing device realize it is independent sealed, so that annular seal space is separated into multiple independent sealing units；
The single sealing device includes isolated tube, the lantern ring and the seal for being sleeved on single protection steel strand wires periphery, described
In the taper hole of isolated tube tail end insertion anchor slab, its front end is connected with the lantern ring, and lantern ring front end is connected with positioning plate；
The lantern ring is the annulus of both ends open, its front end is equipped with the cylindrical step being connected with positioning plate, set
Ring rear end is provided with inner circle stepped hole, and the front end sleeve of the isolated tube is connected in circle stepped hole with the lantern ring inside, isolated tube
The internal layer annular groove of installation seal, the inner periphery in the lantern ring before step are formed between interior step in front end face and inner circle stepped hole
On be provided with least 1 and be used to the outer layer annular groove of seal be installed；The seal includes internal layer sealing ring and at least 1 layer of outer layer is close
Seal, the outer layer sealing ring are installed in the outer layer annular groove of the lantern ring, and the internal layer sealing ring is installed on the internal layer annular groove of the lantern ring
It is interior, thus form that multi-layer sealing structure and internal layer sealing ring directly form with protection steel strand wires from compression seal structure.
Its further technical solution is：The internal layer sealing ring is the lip ring with a cylindrical step, internal layer
Sealing ring is embedded in internal layer annular groove by its large cylindrical and the excircle of its large cylindrical is close in lantern ring inner circle stepped hole
The front end face of isolated tube and the interior step of lantern ring inner circle stepped hole are close in circumference, the two sides of large cylindrical, internal layer sealing ring it is small
In the cylindrical circular hole for being sleeved on isolated tube front end and its small cylindrical excircle is set to be close to the inner periphery of isolated tube, so that internal layer
Sealing ring is directly formed from compression seal structure with protection steel strand wires will isolate the seal of tube.
Further：The internal layer sealing ring and outer layer sealing ring are swollen using high elastic rubber, polyurethane material or chance water
Swollen material is made.
The isolated tube and single protect in the cavity between steel strand wires fill full anti-corrosion material, single close in sealing drum
The full easy cure pastes of filling in cavity between seal apparatus.
Due to the adoption of the above technical scheme, compared with prior art, a kind of guy anchor using single sealing of the present invention
Tool has the advantages that：
1. the internal layer sealing ring of the single sealing device of the present invention is arranged at isolated tube front port, internal layer sealing ring carries one
Cylindrical step, it is small it is cylindrical be inserted directly into isolated tube stomidium, great circle step is close to isolated tube front end face, makes internal layer sealing ring direct
The seal of tube will be isolated by being formed with protection steel strand wires from compression seal structure, even if not having outer layer sealing ring, isolated tube also can be effective
From compression seal；
Additionally, due to internal layer sealing ring it is small it is cylindrical be inserted directly into isolated tube stomidium, have larger contact surface with isolated tube,
Therefore sealing ring compressing area can be increased in the case where not increasing anchorage size, effectively strengthen the waterproof seal of dragline anchorage
Energy, extends the service life of dragline anchorage, eliminates the security risk of bridge cable；
2. seal used in a kind of single sealing device of dragline anchorage using single sealing of the present invention is except interior
At least 1 layer of outer layer sealing ring is further included outside layer sealing ring, the single sealing device of each independence is formed at least more than 2 layers and seals,
Multi-layer sealing structure is formed, its sealing is more safe and reliable；
It is multi-layer sealed additionally, due to using, the adverse effect produced when drag-line offset and vibration to sealing device can be reduced,
Avoid covering annular strain in inhaul cable vibration or offset, moisture enters between the lantern ring and isolated tube causes seal failure；
3. the present invention is using materials such as high elastic rubber, polyurethane or hydro-expansive rubbers as seal, sealing performance
Good, service life length.
