In journey dangerous goods explode) caused by Bridge Accidents be increasing, this closes bridge structure antiknock safety problem increasingly
Note.China not yet issues antiknock protection design Regulations to bridge structure at present, it is therefore necessary to carry out to bridge structure
Antiknock protection design.
The Chinese patent of Publication No. CN205934724U discloses a kind of steel strand stay cable outer tube of collision-damage-prevention, makees
For the anticollision device, collision-prevention device of cable body, is increasing steel pipe outside drag-line HDPE protecting pipe apart from 2.5 meters of high passes of bridge floor, can prevent cable body from meeting with
It is artificially delineated or Vehicular impact.
The Chinese patent of Publication No. CN206204785U discloses a kind of oblique pulling cable body anticollision device, collision-prevention device, which can
To reduce the destruction of accidental impact, while cable body can also be protected from solar exposure, reduce rain wind induced vibration, inhibit vibration, rise
To the effect of protection cable body safety and stability.
The Chinese patent of Publication No. CN106192750A discloses a kind of cable-girder anchorage zone explosion-proof defense of resistance to impact body
System and preparation method thereof, for protecting cable-girder anchorage zone.
Currently, above-mentioned prior art is only the protection to drag-line cable body impact resistance, or the anchorage zone of bridge is mentioned
Antiknock protection technique scheme out, but there has been no the antiknock protection for drag-line cable body.
Utility model content
It is a kind of novel the technical problem to be solved by the utility model is in view of the deficiency of the prior art, provide
Explosion-proof impacts drag-line, increases the function of explosion-proof surge guard on the basis of meeting drag-line function, has drag-line
The ability of explosion is resisted, the explosive attack risk increasingly increased on bridge can be avoided blast impulse directly to Cable
It is destroyed caused by body, it is ensured that the normal operation of guy system, and then bridge collapse caused by also avoiding because of cable collapse
Risk saves bring drag-line renewal cost due to cable collapse, reduces economic loss.
The utility model adopts the following technical solutions to achieve above-mentioned purpose:
A kind of novel explosion-proof impact drag-line, the support tube (2) including drag-line (1), nested drag-line (1), which is characterized in that
Support tube (2) inside and outside wall is equipped with antiknock protective layer (3).
Preferably, support tube (2) the inside and outside wall antiknock protective layer (3) is antiknock protective coating (3b), and the antiknock is anti-
Protecting coating (3b) is that at least one of polyurea coating or polyurethane coating are made.Polyurea coating or polyurethane coating production
Antiknock protective coating be the relatively conventional material of architectural engineering, be easy to spray.
Preferably, support tube (2) the outer wall antiknock protective layer (3) is antiknock protective cloth (3c), the antiknock protective cloth
It is external that (3c) is wrapped in the support tube (2), the antiknock protective cloth (3c) be fiber-reinforced polymer or glass fabric or
At least one of carbon cloth is made.The antiknock of fiber-reinforced polymer or the production of glass fabric or carbon cloth is anti-
Protecting cloth is the relatively conventional material of architectural engineering, is easy to make.
Preferably, outer protection tube (4), the support tube (2) and outer protection tube (4) gap filling is arranged in the support tube (2) outside
Obturator (3a) is protected in antiknock, and antiknock protection obturator (3a) is fibre reinforced concrete, Reactive Powder Concrete, polyureas
Or at least one of polyurethane foam, foamed aluminium, honeycomb aluminum, rubber are made.It is architectural engineering that obturator is protected in antiknock
Relatively conventional material is easy to make, fibre reinforced concrete or Reactive Powder Concrete or polyureas or polyurethane foam or bubble
Under Explosion Loading or large deformation occurs for foam aluminium or honeycomb aluminum or rubber, absorbs explosion impact energy to protect drag-line.
The utility model has the advantage that compared with present technology
1, it on the basis of not changing drag-line original function, increases explosion resistant structure and resists blast impulse.
2, the utility model outer protection tube can be effective against detonation product and fragmentation impact.
3, the utility model antiknock protective layer absorbs explosion impact energy, effective attenuation impact under Explosion Loading
Wave.
4, the utility model structure has duplicate protection, and support tube and outer protection tube can avoid drag-line by direct blast impulse
It destroys, can be improved drag-line uses the time.
