Abstract
A kind of new explosion-proof impact drag-line, support tube (2) including drag-line (1), nested drag-line (1), it is characterized in that, support tube (2) inside and outside wall is provided with antiknock overcoat (3), and the support tube (2) outside can be with nested outer protection tube (4).On the basis of the present invention does not change drag-line original function, explosion resistant structure is added to resist blast impulse, and with sandwich construction protection, drag-line can be avoided to be destroyed by direct blast impulse.
Description
Technical field
The present invention relates to one kind to be applied to science of bridge building, the isostructural drag-line of architectural engineering, and in particular to a kind of new anti-
Blast impulse drag-line.
Background technology
Bridge is respectively provided with vital status as important traffic infrastructure in military traffic and national economy
And effect.Terrorist activity at present in worldwide is increasing, attack of terrorism threat and accidental explosion (such as car operation mistake
In journey dangerous goods explode) caused by Bridge Accidents be on the increase, this makes bridge structure antiknock safety problem increasingly be closed
Note.China not yet issues antiknock protection Design Regulations to bridge structure at present, it is therefore necessary to which bridge structure is carried out
Antiknock protection Design.
Publication No. CN205934724U Chinese patent 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, increasing steel pipe outside drag-line HDPE protecting pipes apart from 2.5 meters of high passes of bridge floor, can prevent cable body from meeting with
Artificially delineated or Vehicular impact.
Publication No. CN206204785U Chinese patent discloses a kind of oblique pulling cable body anticollision device, collision-prevention device, and the outer tube can
To reduce the destruction of accidental impact, while cable body can also be protected from solar exposure, reduce rain wind induced vibration, suppress vibration, rise
To the effect of protection cable body safety and stability.
Publication No. CN106192750A Chinese patent 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.
At present, above-mentioned prior art is only the protection to drag-line cable body impact resistance, or the anchorage zone of bridge is carried
The antiknock protection technique scheme gone out, but there has been no the protection of the antiknock for drag-line cable body.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is that provide a kind of new antiknock
Fried impact drag-line, increases the function of explosion-proof surge guard on the basis of drag-line function is met, drag-line is possessed resistance
The ability of blast, the explosive attack risk increasingly increased on bridge, can avoid blast impulse from directly being made to drag-line cable body
Into destruction, it is ensured that the normal operation of guy system, and then it also avoid the bridge collapse risk caused by cable collapse,
The drag-line renewal cost brought by cable collapse is saved, reduces economic loss.
The present invention takes following technical scheme to realize above-mentioned purpose：
A kind of new explosion-proof impact drag-line, include the support tube (2) of drag-line (1), nested drag-line (1), it is characterised in that
Support tube (2) inside and outside wall is provided with antiknock overcoat (3).
Preferably, support tube (2) the inside and outside wall antiknock overcoat (3) is antiknock protective coating (3b), and the antiknock is prevented
It is that at least one of polyurea coating or polyurethane coating are made to protect coating (3b).Polyurea coating or polyurethane coating make
Antiknock protective coating be the relatively conventional material of architectural engineering, be easy to spray.
Preferably, support tube (2) the outer wall antiknock overcoat (3) is antiknock protective cloth (3c), the antiknock protective cloth
It is outside 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 that fiber-reinforced polymer or glass fabric or carbon cloth make is prevented
It is the relatively conventional material of architectural engineering to protect cloth, is easy to make.
Preferably, the support tube (2) sets outer protection tube (4) outside, and the support tube (2) is filled with outer protection tube (4) gap
Antiknock protection obturator (3a), the antiknock protection obturator (3a) is fibre reinforced concrete, RPC, polyureas
Or at least one of polyurethane foam, foamed aluminium, honeycomb aluminum, rubber are made.Antiknock protection obturator is architectural engineering
Relatively conventional material, it is easy to make, fibre reinforced concrete or RPC 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 so as to protect drag-line.
It is of the invention that there is advantages below compared with present technology：
1st, on the basis of not changing drag-line original function, explosion resistant structure and resistance blast impulse are added.
2nd, outer protection tube of the present invention can be effective against detonation product and fragmentation impact.
3rd, antiknock overcoat of the present invention absorbs explosion impact energy, effective attenuation shock wave under Explosion Loading.
4th, structure of the present invention has duplicate protection, and support tube and outer protection tube can avoid drag-line from being broken by direct blast impulse
It is bad, it is possible to increase the usage time of drag-line.
