Abstract
The utility model discloses a pipe pile combination type bridge pier anti-collision device. The pipe pile combination type bridge pier anti-collision device comprises a pipe pile group, a steel sleeve and a buffer layer; the pipe pile group is arranged around a bridge pier; the steel sleeve sleeves the periphery of the pipe pile group; the buffer layer sleeves the steel sleeve. According to the pipe pile combination type bridge pier anti-collision device, the pipe pile group is arranged around the bridge pier and accordingly the impact force of ships or vehicles is transferred to the bottom surface from the pipe pile group so as to reduce the momentum and delay the collision time is delayed and accordingly the impact resistance of the bridge pier and an anti-collision pier can be significantly enhanced, the protection effect on the bridge pier and the anti-collision pier is achieved, and the device is durable and convenient to maintain.
Description
Technical field
The utility model relates to a kind of anticollision device, collision-prevention device, specifically a kind of pile tube combined type bridge pier anticollision device, collision-prevention device.
Background technology
Pile tube combined type bridge pier anticollision device, collision-prevention device 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.
Therefore,, for overcoming the above problems, need a kind of a kind of anticollision device, collision-prevention device that can reduce that vehicle and bridge pier damage, installation or bridge pier easy to maintenance that provide.
Utility model content
In view of this, the purpose of this utility model is to overcome defect of the prior art, and a kind of pile tube combined type bridge pier anticollision device, collision-prevention device that can reduce that vehicle and bridge pier damage, installation or bridge pier easy to maintenance is provided.Bridge anti-collision device of the present utility model, comprises around the pile tube group of bridge pier setting, is sheathed on the steel cylinder of described pile tube group periphery and is sheathed on the cushion coat outside described steel cylinder;
Further, described pile tube group comprises the multiple pile tubes that circumferentially arrange along bridge pier; Between adjacent two pile tubes, be fixedly connected with elastic rod; Between described pile tube and bridge pier, be provided with damping unit;
Further, described damping unit comprises along bridge pier and is radially fixedly installed on damper and the damping spring between bridge pier and pile tube; Described damping spring is sheathed on outside damper;
Further, described cushion coat comprises the netted bridge cover being sheathed on outside steel cylinder and is located at the air cushion between described netted bridge cover and steel cylinder; Described netted bridge cover comprises that multiple pressure-bearing rods and each pressure-bearing rod head and the tail are connected to form trussed construction;
Further, described pressure-bearing rod is made by crumple material;
Further, described air cushion is cylindrical air cushion.
The beneficial effects of the utility model are: pile tube combined type bridge pier anticollision device, collision-prevention device of the present utility model; around bridge pier, be provided with pile tube group; thereby thereby being delivered to bottom surface by pile tube group, the impact of ship or vehicle cuts down momentum; delay collision time; can significantly strengthen the impact resistance of bridge pier and crash bearer; play the protective effect to bridge pier and crash bearer, and install durable in usely, maintaining is convenient.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, pile tube combined type bridge pier anticollision device, collision-prevention device in the present embodiment, comprise the pile tube group that arranges around bridge pier 6, be sheathed on the steel cylinder 4 of described pile tube group periphery and be sheathed on the cushion coat outside described steel cylinder 4, ground is fixed in pile tube lower end, in the time that bridge pier 6 is subject to clashing into, the suffered impact force major part of this pile tube combined type bridge pier anticollision device, collision-prevention device is delivered to ground by pile tube group, thereby can significantly improve the impact resistance of this anticollision device, collision-prevention device.
In the present embodiment, described pile tube group comprises the multiple pile tubes 5 that circumferentially arrange along bridge pier 6; Between adjacent two pile tubes 5, be fixedly connected with elastic rod 1; Between described pile tube 5 and bridge pier 6, be provided with damping unit, multiple pile tubes 5 can be resisted the shock from bridge pier 6 all directions, pile tube 5 quantity are more simultaneously, the impact resistance of this bridge pier 6 anticollision device, collision-prevention devices is stronger, elastic rod 1 between adjacent two pile tubes 5 can be connected as a single entity 5 groups of whole pile tubes, thereby strengthen the stability of 5 groups of pile tubes, between 5 groups of pile tubes and bridge pier 6, be provided with damper and can avoid pile tube 5 to be damaged after lodging bridge pier 6 is caused to damage; In addition, after pile tube 5 is impacted, its position with respect to bridge pier 6 can be offset, and damping unit can effectively be corrected the skew of pile tube 5 positions.
In the present embodiment, described damping unit comprises along bridge pier 6 and is radially fixedly installed on damper 8 and the damping spring 7 between bridge pier 6 and pile tube 5, described damping spring 7 is sheathed on outside damper 8, and damping spring 7 is for absorbing the suffered impact energy of this pile tube combined type bridge pier anticollision device, collision-prevention device.
In the present embodiment, described cushion coat comprises the netted bridge cover 2 being sheathed on outside steel cylinder 4 and is located at the air cushion between described netted bridge cover 2 and steel cylinder 4; Described netted bridge cover 2 comprises that multiple pressure-bearing rods and each pressure-bearing rod head and the tail are connected to form trussed construction.
In the present embodiment, described pressure-bearing rod is made by crumple material, and in the time that this pile tube combined type bridge pier anticollision device, collision-prevention device is subject to clashing into, pressure-bearing rod pressurized generation crumple, to absorb the impact energy of ship or vehicle, to protect bridge pier 6 not to be damaged.
In the present embodiment, described air cushion is cylindrical air cushion 3, cylindrical air cushion 3 decapacitation increase beyond the buffering effect of this bridge pier 6 anticollision device, collision-prevention devices, can also make netted bridge cover 2 rotate with respect to steel cylinder 4, in the time of ship or Vehicular impact bridge pier 6, netted bridge overlaps 2 and stressedly rotates with respect to steel cylinder 4, thereby ship or vehicle are played to guide effect, reduces the damage of bridge pier 6.
