Description
Technical field
The present invention relates to Bridge Pier technical field, especially a kind of pier anticollision guard ring.
Background technology
Along with the development of economy and communications and transportation, bridge become urban road, mountain highway, across important component parts such as water channel road, railways.Special for complicated city intersection or across water bridge, the bridge pier that bridge often occurs is knocked and causes the impaired accident of bridge, and economic loss is huge.Therefore, the anticollision device, collision-prevention device of bridge is widely studied.Existing anticollision device of pier is varied, the form such as guardrail or fence is reinforced in most employing, the form adopting steel concrete to build arranges block, not only affect bridge attractive in appearance, construction inconvenience, and rigid concrete block etc. does not have energy-absorbing function, cannot consume clashing into the large energy produced, the anti-collision effect for great shock accident is limited.
Use through years of researches, occurred the multiple pier anticollision facility for bridge collision both at home and abroad, but its general principle cushions and designs based on energy absorption, momentum, often kind of anti-collision facility has its feature and service condition.Wherein direct-type anti-collision facility, power acts directly on bridge pier after buffering, as protected string mode, rope mode of texturing, padded coaming implementation, fender system engineering mode and fixing or floating casing anti-collision facility etc.When ship collision steel jacket box anticollision device, collision-prevention device, there is large distortion in anti-collision structure skin discontinuous (interruption) structural steel and iron, absorb local collision energy, and extend time of contact, impact peak value is minimized, simultaneously due to malformation and interaction, thus stir fore direction, decrease boats and ships and interstructural energy exchange.But steel jacket box bears single impact usually, keep in repair more difficult after damage; Hull subject to damage during collision simultaneously; Steel easy-to-rust in water throughout the year in addition, maintenance cost is higher.Meanwhile, the energy dissipating time of existing crashproof guard ring is short, and effect of energy dissipation is poor.
Summary of the invention
The technical problem to be solved in the present invention is: in order to the energy dissipating time overcoming crashproof guard ring of the prior art is short, the problem of effect of energy dissipation difference, the invention provides a kind of pier anticollision guard ring, can according to the shape and size of different bridge pier, produce corresponding anti-collision unit, anti-collision unit can be connected by connector, Fast Installation and dismounting can be reached, and can change local anti-collision unit, cost-saving, and first crashproof guard ring be provided with the isosceles trapezoid groove and square projection that are embedded and are connected between the second crashproof guard ring, there is energy-absorbing energy-dissipating effect, the energy dissipating time is long, anti-collision effect is obvious, can available protecting bridge pier.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pier anticollision guard ring, comprise: around the first crashproof guard ring be arranged on around bridge pier and the second crashproof guard ring be looped around around described first crashproof guard ring, the first connector that described first crashproof guard ring comprises several first anti-collision units and coupled together by several first anti-collision units, the second connector that described second crashproof guard ring comprises some second anti-collision units and coupled together by several second anti-collision units, described first anti-collision unit offers axial isosceles trapezoid shape groove, the handle of described isosceles trapezoid is away from described second anti-collision unit, described second anti-collision unit offers square projection, described projection is towards the groove of described first anti-collision unit,
