Description
Technical field
The utility model belongs to bridge road field, relates in particular to a kind of anticollision device, collision-prevention device of bridge pier.
Background technology
Ship (car) hits bridge accident and is constantly occurring all over the world always, and the frequency that ship hits bridge accident is higher more than our imagination.It is surprising hitting by ship casualties, property loss and the environmental disruption that bridge accident causes.A lot of ships hit bridge accident and gently lose tens thousand of units, and heavy casualties is lost in millions of, tens million of even multi-million dollars, and a large amount of indirect losses is difficult to calculate especially.Therefore take Anticollision Measures particularly necessary to bridge, its basic goal is: prevent bridge chance boats and ships (vehicle) impact and recurring structure breaking-up, the while is protected boats and ships (vehicle) as much as possible, and loss is reduced to a minimum.
Anticollision device of pier is a kind of endergonic structure.Distortion by device absorbs collision energy, and changes accident vehicle direction with protection bridge pier, in protection bridge pier, also will reduce to greatest extent the damage to passenger.Traditional bridge pier protector has the crashproof fence of rigidity and flexible protection fence.The crashproof fence of rigidity is that crashproof at bridge pier arranges indeformable guard bar device, principal mode is concrete guardrail, stiff safety fence has played the effect of protection bridge pier to a certain extent, but in the time that the intensity of clashing into is larger, rigid protection fence does not just have effective protective action, and accident vehicle or ship are caused to very large damage; Flexible protection facility has larger buffering energy-absorbing performance, and principal mode is rubber anti-collision device, but rubber anti-collision apparatus cost is higher, can not be widely applied in each engineering, and rubber can be aging gradually in natural environment, reduces crashworthiness.If bridge pier stands in water, the protector of bridge pier not only just protects bridge pier not clashed into, and also wants to protect bridge pier not to be subject to the erosion of some corrosive substances and the impact of silt in water body.Traditional protective fence anticorrosive property is poor, and changes and need professional construction equipment after damaging.
Utility model content
The technical problems to be solved in the utility model is: the anticollision device of pier that a kind of absorbing impact energy type is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of anticollision device of pier, comprise composite material fixed bed and anticollision barrier, composite material fixed bed fixed packet is overlying on the bridge pier external surface of water surface top, on the external surface of composite material fixed bed, offer the hole of outwardly convex
Two ports of anticollision barrier, are bolted, are fixedly plugged in two holes, and anticollision barrier of two hole fixed supports, if ship and bridge pier clash into, anticollision barrier will take the lead in directly contacting with hull.To the region of the port of anticollision barrier, be radially fixedly installed 1 waddy from the bottom of hole, many waddys also can be set, between waddy and waddy, (in the direction of " bottom of hole is to the port of anticollision barrier ") has certain gap,
On the external surface of composite material fixed bed; the length of anticollision barrier will design according to empty spacing; the distribution of hole is intensive as far as possible; to such an extent as to can have abundant anticollision barrier stationary distribution on the external surface of composite material fixed bed, jointly composite material fixed bed and bridge pier are played a protective role.
Wherein, composite material fixed bed and anticollision barrier, adopt glass fibre reinforced composion to make, and matrix material is unsaturated-resin or vinylite; Reinforcing material is glass fiber or carbon fiber.
The beneficial effects of the utility model are: the utility model adopts glass fibre reinforced composion to replace traditional elastomeric material, reduced cost, avoided the corrosive attack of the corrosive goods confrontation bridge pier protective material in river.
In the bottom of hole to the port of anticollision barrier, radially be fixedly installed successively some waddys, when on river surface, when hull strikes anticollision barrier, even if shock dynamics is very large, cause " the bolt connection " of fixing anticollision barrier destroyed fall, now, some waddys that the bottom of hole to the port of anticollision barrier is fixedly installed, can be used as the backing of " bolt connection ", support anticollision barrier, avoid the port of anticollision barrier to be subject to the shock of hull and directly to knock the composite material fixed bed that is coated on bridge pier external surface, thereby further bridge pier is formed to protection.

Detailed description of the invention
As shown in Figure 1: a kind of anticollision device of pier, comprise composite material fixed bed 1 and anticollision barrier 2, composite material fixed bed 1 fixed packet is overlying on the bridge pier external surface 3 of water surface top, on the external surface of composite material fixed bed 2, offer the hole 4 of outwardly convex, two ports 5 of anticollision barrier 2, fixedly be plugged in two holes 4 anticollision barrier 2 of two hole 4 fixed supports;
If ship and bridge pier clash into, anticollision barrier 2 will take the lead in directly contacting with hull.On the external surface of composite material fixed bed 1; the distribution of hole 4 is intensive as far as possible; to such an extent as to can have abundant anticollision barrier 2 stationary distribution on the external surface of composite material fixed bed 1, jointly composite material fixed bed 1 and bridge pier are played a protective role.
As shown in Figure 2: two ports 5 of anticollision barrier 2, connect by bolt 9, be fixedly plugged in two holes 4, to the port 7 of anticollision barrier 2, be radially fixedly installed a waddy 8 from the bottom 6 of hole 4.When on river surface; when hull strikes anticollision barrier 2; even if shock dynamics is very large; cause " the bolt connection " of fixing anticollision barrier 2 destroyed fall, now, the waddy 8 that the bottom 6 of hole 4 is fixedly installed to the port 7 of anticollision barrier 2; can be used as the backing of " bolt connection "; support anticollision barrier 2, avoid the port 5 of anticollision barrier 2 to be subject to the shock of hull and directly to knock the composite material fixed bed 2 that is coated on bridge pier external surface 3, thereby further bridge pier is formed to protection.
Composite material fixed bed and anticollision barrier in the present embodiment, adopt glass fibre reinforced composion to make, and matrix material is unsaturated-resin; Reinforcing material is glass fiber.
