Abstract
The invention relates to the technical field of the pier protection and in particular relates to a flexible pier collision avoidance ring. The flexible pier collision avoidance ring comprises a collision avoidance ring arranged to surround a pier; the collision avoidance ring comprises a plurality of collision avoidance units and connection units for connecting the plurality of collision avoidance units together; each collision avoidance unit comprises a cylindrical airtight housing, the housing is cut off by a section perpendicular to the axis of the housing to form a cross section, the outer wall of the cross section is circular, while the inner wall of the cross section is regularly hexagonal, a metal reinforcing inner wall is arranged at the inner side of the housing, a plurality of filling holes in the axial direction of the housing are formed in the center of the metal reinforcing inner wall, and the filling holes are filled with an energy dissipation material. The flexible pier collision avoidance ring is characterized in that the steel reinforcing inner wall is arranged in the housing made of a composite material to guarantee that collision energy can be absorbed to a large extent when the collision avoidance ring is impacted, and furthermore, the contact time is increased, the peak of the impact force can be reduced and energy exchange between a ship and the pier is reduced, and as the composite materials is excellent in corrosion resistance, the collision avoidance ring can be used for 50 years.
Description
Technical field
The present invention relates to Bridge Pier technical field, especially a kind of flexible pier anti-collision ring.
Background technology
Along with being surging forward of transport development, boats and ships can constantly increase the collision accident of bridge.As the countermeasure that prevents of this type of accident, the first, guarantee has enough navigation channels, and strict implement and utilization towing method and navigation supporting facility, to avoid boats and ships near the deathtrap of bridge.The second, in bridge deathtrap, protective equipment is set, make impact damage be reduced to bottom line.
Through years of researches, use, steel jacket box has good crashproof effect.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, absorbed local collision energy, and extended time of contact, impact peak value is minimized, simultaneously due to malformation and interaction, thereby stir fore direction, reduced boats and ships and interstructural energy exchange.But steel jacket box is easy-to-rust in water throughout the year, and maintenance cost is higher, greatly limited its use.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve in prior art steel jacket box easy-to-rust in water throughout the year, the problem that maintenance cost is higher, the invention provides a kind of flexible pier anti-collision ring, steel is strengthened to inwall to be arranged in material shell, can guarantee can absorb largely collision energy when anti-collision ring is received shock, extended time of contact, impact peak value is minimized, reduced the energy exchange between boats and ships and bridge pier, simultaneously, material shell corrosion resistance is strong, and Use Limitation is 50 years.
The technical solution adopted for the present invention to solve the technical problems is: a kind of flexible pier anti-collision ring, comprise around being arranged on bridge pier anti-collision ring around, described anti-collision ring comprises several anti-collision units and the linkage unit that several anti-collision units are coupled together, described anti-collision unit comprises cylindrical enclosure housing, described housing is cut off formation cross section with the perpendicular cross section of housing axis, described cross section outer wall is rounded, inwall is regular hexagon, described housing inner side is provided with layer of metal and strengthens inwall, described metal is strengthened the filler opening that inwall center is provided with some housing axis directions, in described filler opening, be filled with energy dissipating material.
Select cross section to be orthohexagonal reinforcement inwall, more stable, when occurring to clash into, can effectively transform collision energy, make collision energy be converted into the deformation of strengthening inwall, to subdue collision energy.
As preferably, described housing is a kind of in unsaturated-resin, isophthalic resin, adjacent benzene resin, vinylite, epoxy resin, bisphenol A-type resin, reactive resin.
Particularly, be provided with the glass fibre reinforced composion of some housing axial directions in described housing, described glass fibre reinforced composion is a kind of of glass fiber, carbon fiber, aramid fiber or composite fibre.
Particularly, described energy dissipating material is for being polyurethane foam, haydite or rubber grain.
Particularly, described reinforcement inwall is that stainless steel is strengthened inwall.
Particularly, described linkage unit is chain.
The invention has the beneficial effects as follows, a kind of flexible pier anti-collision ring provided by the invention, steel is strengthened to inwall to be arranged in material shell, can guarantee can absorb largely collision energy when anti-collision ring is received shock, extended time of contact, impact peak value is minimized, reduced the energy exchange between boats and ships and bridge pier, simultaneously, material shell can be along with the rising whereabouts free floating of water level in ocean, material is acidproof, alkaline-resisting, crashproof, energy dissipating reaches 70%, Use Limitation 50 years.
