The novel stay cable HDPE waterproof jacket comprises an outer layer and an inner layer, wherein the outer layer comprises a waterproof component, the waterproof component comprises a body and a hot melting section, and the body comprises a cover and a transition section connecting the cover with the hot melting section; the inner layer comprises a stay cable jacket layer, the hot melting section is arranged on the stay cable jacket layer, and the hot melting section and the stay cable jacket layer are integrated in a hot melting mode. The novel stay cable HDPE waterproof jacket has the advantages that the waterproof cover is tightly combined with the stay cable jacket layer in a sealed mode, so that water can not enter an embedded pipe when a stay cable is subjected to long-term vibration, and the problem of water inflow caused by vibration of the stay cable can be completely solved.
Description
Technical field
The present invention relates to, in highway bridge construction technical field, prevent more particularly to a kind of Novel inclined drag-line HDPE
Water cover.
Background technology
The design service life requiring suspension cable in national standard is 30 years, but for various reasons, Hen Duoyuan
It is not reaching to 30 years occur as soon as disease, causes drag-line corrosion even to rupture, greatly affect normally making of bridge
With.The main cause causing suspension cable durability and safety not enough is the corrosion of inner wire and anchorage, main
If anchored end water inlet causes, and from the point of view of rope situation is changed in various places, the corrosion of drag-line is concentrated mainly on drag-line bridge
Near the anchorage point of face, i.e. waterproof becoming at the built-in pipe mouth of pipe restricts drag-line anticorrosion and the key of durability.
At present at anchored end built-in pipe, the mode of waterproof main employing has 3 kinds: the first is cylinder iron bucker,
The advantage of this bucker is easy for installing and changing, but owing to suspension cable Cheng Qiaohou is in constantly vibration, it
Structure be that two halves are embraced on suspension cable, itself connects by bolt is fixing, is easily generated seam with suspension cable junction
Gap, As time goes on waterproof effect weakens；The second is rustless steel bucker, and its advantage is certainly
Body is antirust, be hardly damaged, and is that the rubber cover by two halves formula seals with suspension cable junction, and rubber cover also leans on
Bolt is fixing to be connected, due to Inclined Cable Vibration, it may appear that gap causes waterproof effect to reduce；The third is rubber
Glue bucker, its advantage is rubber deformable, is tightly combined with suspension cable, and waterproof effect is pretty good, shortcoming
It is that rubber can not merge into an organic whole with suspension cable restrictive coating, after suspension cable constantly vibrates, easily occurs that gap is drawn
Play built-in pipe water inlet.These three waterproof type, based on there being bolt connecting mode, needs later maintenance, increases
Maintenance cost.It addition, occur in that a kind of shape sealed with aluminium foil aerated capsule at embedded pipe orifice in recent years
Formula, this seal form be aluminium foil is put into embedded pipe orifice after reinflated, utilize the pressure of gas reach seal
Effect, but due to the compressibility of gas and the vibration of suspension cable, after a while, seal
Effect will reduce, and after inflating, the sealing of QI KOU is bad will also result in gas leakage so that seal failure.Tiltedly
Corrosion caused by drag-line waterproof failure does not only have safeguard structure system, protective material and improves the former of aspect not
Cause, also has a reason of the aspects such as making, installation quality defect and final-period management maintenance, the most very important tiltedly
The vibration effect of drag-line.Bridge changes rope and is the most all because the waterproof failure of stayed structure, stressed wire or anchorage
There occurs serious corrosion, section weakens, depression of bearing force, especially severe even cause fracture of wire, lose completely
Lose bearing capacity.
Therefore, it is necessary to study a kind of novel oblique pull string water proof cover, bucker is made to be combined with suspension cable restrictive coating
Place forms tight sealing, reaches suspension cable in the case of Long-term Vibration, the requirement that built-in pipe is not intake.
Summary of the invention
For above-mentioned situation, the invention provides a kind of Novel inclined drag-line HDPE bucker, solve tradition
Oblique pull string water proof cover deform in the case of suspension cable Long-term Vibration and cause waterproof effect to decline, ultimately result in anti-
Water failure, stressed wire or anchorage there occurs serious corrosion, section weakening, the problem of depression of bearing force.
For achieving the above object, present invention employs following technical scheme: a kind of Novel inclined drag-line HDPE prevents
Water cover, including outer layer and internal layer, described outer layer includes that the flashing member of hollow, described flashing member include HDPE
Body that material is made and hot melt section, described body includes cover body, connects the cover body changeover portion with hot melt section,
Described internal layer includes that the suspension cable restrictive coating that HDPE material is made, described hot melt section are located on suspension cable restrictive coating,
Described hot melt section and suspension cable restrictive coating are hot melten type integrative-structure.
Further, described body is funnel-form, and described cover body internal diameter is more than suspension cable restrictive coating internal diameter, described
Changeover portion and suspension cable restrictive coating angulation are α.
Further, described cover body is cylinder.
Further, described body is provided with guiding gutter.
Further, the suspension cable restrictive coating that described body is wrapped up is provided with the variable color layer of silica gel containing cobalt oxide,
Described body is that HDPE material is made.
To sum up, there is advantages that the hot melt section due to flashing member and suspension cable restrictive coating
It is HDPE material to make, and is hot melten type integrative-structure, because HDPE material possesses advantages below: 1,
Interface is reliable and stable: hot melt section and suspension cable restrictive coating are homology material, and hot melten type integrative-structure connects
The intensity of head is equal to pipeline body intensity；2, low-temperature impact resistance is good: the brittle temperature pole of HDPE material
Low, can use safely in-60-60 DEG C of temperature range, during winter construction, because of material good impact resistance, no
Embrittlement can occur；3, anti-stress cracking is good: it is strong that HDPE material has low notch sensitivity, high shearing
Degree and excellent scratch-resistant ability, environmental stress cracking resistance is the most prominent；4, chemical resistance is good:
HDPE material can the corrosion of resistant to many chemical mediator, be the insulator of electricity, thus without rotting, getting rusty
Or electrochemical corrosion phenomenon, it also will not promote algae, antibacterial or fungus growth in addition；5, ageing-resistant, make
Use the life-span long: the HDPE material of the equally distributed carbon black containing 2-2.5% can be at outdoor outdoor storage or make
With 50 years, will not damage because suffering ultraviolet radiation；6, wearability is good: HDPE material is resistance to steel
Mill property contrast test shows, the wearability of HDPE material is 4 times of steel, has more preferable wearability, this
Mean that HDPE material has longer service life and more preferable economy.Because its interface is stable, anti-impact
Hit, resistance to stress, cracking resistance, the series of advantages such as ageing-resistant, corrosion-resistant, make HDPE bucker and suspension cable
Restrictive coating junction forms tight sealing, reaches suspension cable in the case of Long-term Vibration, and built-in pipe is not intake
Requirement, can thoroughly solve the water inlet problem that Inclined Cable Vibration causes, the skill of General Promotion suspension cable durability
Art level assurance drag-line is used safely, increases the service life, and prolongation is changed the rope cycle and even avoided changing rope, smoothly
Reach even to surmount expected service life, play maximum benefit.
