Abstract
The utility model belongs to the technical field of bridge safety, and particularly relates to a protection device of a pier, in particular to a reinforced anti-collision energy-dissipation ring. The anti-collision energy-dissipation ring is formed by connecting a plurality of energy-dissipation units through bolts, each energy-dissipation unit is provided with a through hole which penetrates through two sections of the energy-dissipation unit, the direction of each through hole is consistent with that of the corresponding energy-dissipation unit in structure, and a closed annular rope sequentially penetrates through the through holes of the energy-dissipation units, so that all the energy-dissipation units are connected. After the energy-dissipation units are connected by means of the closed rope, the rope can still bind the energy-dissipation units and collect the energy-dissipation units around the pier even if all the bolts for connecting and fixing the energy-dissipation units lose efficacy, so that the anti-collision energy-dissipation ring is formed, and the situation that the energy-dissipation units are separated and the pier is exposed is avoided.
Description
Technical field
The utility model belongs to the technical field of bridge security, particularly a kind of protector of bridge pier.
Background technology
Along with being showing improvement or progress day by day of Science & Society, the size of ship and tonnage, and the density of gap bridge ship all had than in the past significantly and to increase, and the speed of ship is also significantly improving, and the accident of ship collision with piers occurs again and again.On June 15th, 2007, Guangdong Jiangmen Jiujiang Bridge is severed by the waist by a sand carrier, and falling completely in river in approximately 160 meters, bridge stage casing, causes serious economic loss and casualties.Therefore, safety and design about bridge pier, more and more come into one's own.
In prior art, have multiple pier anticollision facility, commonplace is anticollision energy eliminating circle, and anticollision energy eliminating circle is generally bolted and is formed by several energy dissipating unit, forms an annular, and bridge pier is protected.Because volume, the weight of energy dissipating unit are generally all larger, such large component is connected by several bolts, original bonding strength was just insecure, and bolt connects and tend to the passage due to the time, and become flexible, lost efficacy (such as reasons such as screw thread are polished).And on anticollision energy eliminating circle, a plurality of being threaded after inefficacy, may cause energy dissipating unit to depart from anticollision energy eliminating circle, and bridge pier is exposed to outside.
Utility model content
The technical problems to be solved in the utility model is: anticollision energy eliminating circle is bolted by several energy dissipating unit, connects insecurely, and after having grown service time, is threaded and easily loses efficacy.
The utility model solves the technical scheme that its technical problem adopts: a kind of anticollision energy eliminating circle, by several energy dissipating unit, to be bolted the anticollision energy eliminating circle of the rectangular ring forming, on each energy dissipating unit, offer through hole, through hole runs through two cross sections of energy dissipating unit, and through hole trend is consistent with energy dissipating unit trend structurally, article one, closed looped ropes, successively through the through hole of each energy dissipating unit, couples together each energy dissipating unit
The benefit of design is like this: due to the volume of energy dissipating unit, weight is generally all larger, only by several bolts, connect, original bonding strength is just undesirable, add in use, the reasons such as screw thread is easily polished, bolt connects and can generation become flexible, lost efficacy, and by closed rope, after each energy dissipating unit is coupled together, even if connect, fixedly all bolts of energy dissipating unit had all lost efficacy, rope still can be by each energy dissipating unit binding, concentrate on bridge pier around, form anticollision energy eliminating circle, avoided energy dissipating unit to depart from, and bridge pier is exposed to outside,
As preferably: the cross section of each energy dissipating unit is circular, through hole cross section is also circular, and the center of circle in cross section, energy dissipating unit and the center of circle of through hole cross section are overlapping,
So just guaranteed that energy dissipating unit is consistent at each material thickness in the radial direction, when ship clashes into bridge pier and anticollision energy eliminating circle (energy dissipating unit) shock, on anticollision energy eliminating circle, with regard to not there is too weak stress point, directly cause anticollision energy eliminating circle (energy dissipating unit) to be damaged;
As preferentially: be matched in clearance between through hole and rope, offer in energy dissipating unit like this under the prerequisite of through hole, guaranteed as much as possible the material thickness on energy dissipating unit, thereby while having guaranteed that energy dissipating unit and ship clash into, possess certain holding capacity;
As preferably: rope adopts nylon fibre braiding to form, the breaking strength of nylon fibre can reach 3.5～9.5g/D in dry state situation, in hygrometric state situation, can reach 2.6～8.0g/D, there is high-tensile and anti-wear performance, cost is lower, also applicable under hygrometric state water environment.

Wherein, 1-bridge pier, 2-energy dissipating unit, 3-bolt, 4-through hole, the cross section of 5-energy dissipating unit, 6-rope.
The specific embodiment
The utility model provides a kind of anticollision energy eliminating circle, it is the anticollision energy eliminating circle of a rectangular ring being formed by connecting by bolt 3 by several energy dissipating unit 2, on each energy dissipating unit 2, offer through hole 4, through hole 4 runs through two cross sections 5 of energy dissipating unit 2, and through hole 4 trends are consistent with energy dissipating unit 2 trend structurally, article one, closed looped ropes 6, successively through the through hole 4 of each energy dissipating unit 2, couples together each energy dissipating unit 2
Volume due to energy dissipating unit 2, weight is generally all larger, only by several bolts 3, connect, original bonding strength is just undesirable, add in use, the reasons such as screw thread is easily polished, bolt connects and can generation become flexible, lost efficacy, and by closed rope 6, after each energy dissipating unit 2 is coupled together, even if connect, fixedly all bolts 3 of energy dissipating unit 2 had all lost efficacy, rope 6 still can be by each energy dissipating unit 2 bindings, concentrate on bridge pier 1 around, form anticollision energy eliminating circle, avoided energy dissipating unit 2 to depart from, and bridge pier 1 is exposed to outside,
Wherein, the cross section 5 of each energy dissipating unit 2 is circular, and through hole 4 cross sections are also circular, and the center of circle of the center of circle in 2 cross sections, energy dissipating unit and through hole 4 cross sections is overlapping,
So just guaranteed that energy dissipating unit 2 is consistent at each material thickness in the radial direction, when ship clashes into bridge pier and anticollision energy eliminating circle (energy dissipating unit) shock, on anticollision energy eliminating circle, with regard to not there is too weak stress point, directly cause anticollision energy eliminating circle (energy dissipating unit) to be damaged;
Between through hole 4 and rope 6, be matched in clearance, in energy dissipating unit 2, offer like this under the prerequisite of through hole 4, guaranteed as much as possible the material thickness on energy dissipating unit 2, thereby while having guaranteed that energy dissipating unit 2 clashes into ship, possess certain holding capacity;
Rope 6 adopts nylon fibre braiding to form, the breaking strength of nylon fibre can reach 3.5～9.5g/D in dry state situation, in hygrometric state situation, can reach 2.6～8.0g/D, there is high-tensile and anti-wear performance, cost is lower, also applicable under hygrometric state water environment.
