Description
Technical field
Patent of the present invention relates to a kind of bridge extension joint technical field, especially relates to the flexible dress of a kind of sand prevention noise reduction
Put.
Background technology
Along with the fast development of China's economic construction, the high-grade highway with highway as representative emerge rapidly in large numbersBamboo shoots after a spring rain as go out
Existing, the bridge construction as highway construction important component part is developed the most accordingly.Highway communication sharply increases, and people are to row
Car comfortableness and minimizing noise etc. require more and more higher.Sand laying dust that in the past retractor device in use occurred, maintenance
The problems such as inconvenience, impact noise is big, service life is short become increasingly to highlight.
The retractor device that present stage commonly uses, whether shaped steel (modulus type) retractor device or the flexible dress of fishback
Putting, all there is gap in the part being exposed to road surface, thus can be invaded by rubbish and sandstone.It is flexible that shaped steel (modulus type) forms
Device is to be formed less than the shaped steel combination in 80mm gap by per pass, is easily invaded by sandstone and rubbish, piles up, and is difficult to clear
Remove.The accumulation of rubbish will have a strong impact on Telescopic.Between the tooth plate of fishback retractor device, rubbish the most easily piled up by deep trouth, simultaneously
Cannot clear up, in dust sandy soil enter deep trouth, at the roller compaction process of vehicle, tooth plate vibrates, and dust sandy soil will invade tooth
Between plate and rustless steel, causing frictional force to increase, rustless steel damages, and tooth plate is elevated, pavement roughness.Rubbish sandstone simultaneously
Constantly piling up, had a strong impact on tooth plate normally conjugates requirement, even causes retractor device thoroughly to lose effect.For flexible dress
Put and prevent rubbish from invading problem, late maintaining can only be relied on to keep in repair, and additionally increase the maintenance work of retractor device.Simultaneously because
The time restriction of maintenance, if can not maintenance in time, severe patient may cause retractor device lost efficacy and accidents caused.
