Abstract
The invention relates to a tarpaulin for a stay cable and a beam end. The tarpaulin comprises a tarpaulin body (3), wherein a small end of the tarpaulin body (3) and a cable body (1) are fitted closely, the front end of the small end of the tarpaulin body (3) is provided with a first groove (8), the middle part of the small end of the tarpaulin body (3) is provided with a second groove (9), a seal ring (5) is arranged in the second groove (9), a large end of the tarpaulin body (3) is provided with a third groove (10), and a first seal strip (4) is arranged in the third groove (10). The first seal strip, the seal ring and a second seal strip of the tarpaulin for the stay cable and the beam end form three defensive lines for preventing moisture from entering a water shield, pre-compression deformation generated by the seal ring is used to adapt to the clearance generated by the vibration of the stay cable and the like, dynamic adaptive sealing effects of the cable body of the stay cable and the clearance is realized, and the durability of connecting transition part of the stay cable and the beam end is improved.
Description
Technical field
The present invention relates to a kind of suspension cable, belong to technical field of bridge engineering.
Background technology
Suspension cable is the main load-carrying member of cable stayed bridge, and its durability directly affects safety, economy and the reliability of cable stayed bridge.The durability of suspension cable mainly comprises that the durability of suspension cable system, suspension cable form with the durability that is connected excessive position of beam-ends with suspension cable with tower end.In recent years, the durability of suspension cable system by factory, carry out outside steel tendon hot extrude permanent seal cooling high density polyethylene (HDPE) sheath, in ground tackle, pour into the measures such as sealed filling material and effectively guaranteed.
For bucker of beam-ends operated by rotary motion of suspension cable, this bucker one end is connected with the built-in pipe of cable stayed bridge, and one section is connected with suspension cable, and the large small end of bucker coordinates with the periphery that two diameters do not wait simultaneously.In actual installation, owing to cannot realizing bucker and two periphery while no-floats, generally to guarantee that large end coordinates with built-in pipe periphery, small end and suspension cable periphery are reserved certain gap, after installation, in the gap between bucker small end and drag-line, insert silastic sealing strip and fluid sealant.But in the practice of construction process at bridge, built-in pipe and oblique pulling cable body cannot reach desirable concentric, and suspension cable be in operation also can be because vehicular load vibrates, so silastic sealing strip and fluid sealant cannot play waterproof effect.In actual use, in the built-in pipe of discovery suspension cable beam-ends, there is a large amount of ponding, cause suspension cable anchor head to be immersed in water, affect the result of use of suspension cable.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of suspension cable beam-ends tarpaulin that moisture content enters bucker of having stopped is provided.
The object of the present invention is achieved like this:
A kind of suspension cable beam-ends tarpaulin, be characterized in: described tarpaulin comprises tarpaulin body, small end and the cable body of described tarpaulin body fit tightly, the front end of tarpaulin body small end is provided with the first groove, in the first groove, be provided with the second weather strip, the middle part of described tarpaulin body small end is provided with the second groove, in the second groove, is provided with sealing ring, the large end of described tarpaulin body is provided with the 3rd groove, in the 3rd groove, is provided with the first weather strip.
A kind of suspension cable beam-ends of the present invention tarpaulin, its first weather strip, sealing ring and the second weather strip adopt silastic material to make.
A kind of suspension cable beam-ends of the present invention tarpaulin, its tarpaulin is for breathing out furan structure and adopting stainless steel or carbon steel material is made.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of suspension cable beam-ends of the present invention tarpaulin, its first weather strip, sealing ring and the second weather strip form and prevent that moisture content from entering the three lines of defence of bucker, rely on sealing ring to produce the gap that precommpression is out of shape to adapt to the generations such as Inclined Cable Vibration, the dynamic self-adapting sealing effectiveness of realization and oblique pulling cable body, has improved the durability that be connected excessive position of suspension cable with beam-ends.
