Description
Technical field
The utility model relates to aquatic building technical field of safety protection, particularly relates to a kind of pier anticollision composite material intercepting system.
Background technology
Along with the development of transportation, over strait, crossing-fiver bridge is constantly built in a large number.And the residing river of this bridge itself, marine site are mostly busy navigation channels, the situations such as its current, great waves, stormy waves are complicated, and bridge inevitably carries the risk of certain ship collision.Under non-situation, boats and ships grazing or when clashing into bridge pier, the crash bearer of bridge, the momentum with the boats and ships of certain speed is very large, according to momentum theorem: mv1-mv2=F Δ t, Δ t are moments, and thus its impact is huge, damages bridge and happens occasionally.When the bridge pier of bridge is by boats and ships grazing continuous action, the huge kinetic energy that boats and ships have is converted to swing, the vibration of bridge pier when touching bridge, and crane span structure is the beam of narrow square-section, its lateral bending and torsional stiffness little, producing crane span structure bending when the runout effect of bridge pier exceedes the bending of crane span structure and torsional stiffness loses hidden, the flexing of result generation lateral bending and torsion, causes crane span structure to rupture caving in (well-known at home and abroad " Jiujiang Bridge 615 vessel bump bridge break accident " is therefore sent out).
In order to the shock reducing boats and ships causes damage to bridge pier as far as possible, usually anticollision box can be set on bridge pier, or double-walled crash-proof steel bushing box, or flexible energy-absorbing anti-impact structure, reach the object of protection bridge pier.Wherein, anticollision box or double-walled crash-proof steel bushing box are used for stopping boats and ships, consume the kinetic energy of boats and ships, boats and ships are slowed down, and delay to clash into, and weaken boats and ships to the impact of bridge pier; And flexible energy-absorbing anti-impact structure utilizes steel to enclose the flexible energy system jointly formed with wire rope-rubber combined anti-collision ring, consume boats and ships kinetic energy, boats and ships are slowed down, delay to clash into, weaken boats and ships to the impact of bridge pier.Due to boats and ships grazing or when clashing into the generation of bridge pier situation, Offending Ship kinetic energy is huge, anticollision box, double-walled crash-proof steel bushing box and flexible energy-absorbing anti-impact structure due to the elastic buffer amount of material very limited, small-sized boats and ships can only be prevented, the boats and ships slightly larger for quality or the speed of a ship or plane is slightly large, just well can not absorb the huge kinetic energy of boats and ships, its energy dissipating, anti-collision effect is not good enough, easily break, potential safety hazard still exists, application life is also shorter, need after breaking to change immediately, anticollision box is formed by Plate Welding, it is a huge monster, weigh thousands of tons of, not easily install, perishable after galling, affect application life.Thus, the existing protector to bridge pier needs further improvement.
Utility model content

The utility model solves the technical scheme that its technical problem adopts: a kind of pier anticollision composite material intercepting system, comprise multiple spaced composite material buoyancy aid, a catch net is provided with between adjacent two described composite material buoyancy aids, described catch net is fixedly connected with described composite material buoyancy aid, described composite material buoyancy aid is connected with the pool anchor device for locating, the housing that described composite material buoyancy aid comprises fibre reinforced plastics material and the damping body of filling in the housing, described intercepting system becomes triangular waveform to arrange, described multiple composite material buoyancy aid is separately positioned on crest or the trough place of described triangular waveform.
As preferably, described catch net is worked out by high-strength nylon rope, and the outer wrap of described high-strength nylon rope has the anticorrosive coat of fibre reinforced plastics material.
As preferably, each described catch net is fixed with three keg floats.
As preferably, described pool anchor device comprises anchor chain, sinker and gravity anchor, and the two ends of described anchor chain are fixedly connected with the bottom of described sinker with composite material buoyancy aid respectively, and described gravity anchor is fixed on the bottom of described sinker.
As preferably, adjacent two described catch net angulations 45 ~ 150 °.
As preferably, the material of described damping body is the one in light wood, polyurethane foam, PVC foam, PEI foam, PMI foam, polyvinyl chloride foam, carbon foam, polyphenyl mortar, rubber tyre, rubber grain, block rubber, polyimide foam or strong core felt.
As preferably, described fibre reinforced plastics adopt fiber and resin to make, described fiber is the one in carbon fiber, glass fiber, basalt fibre, aramid fiber, assorted fibre, and described resin is the one in unsaturated polyester (UP), adjacent benzene resin, vinylite, epoxy resin, inorganic resin or thermoplastic resin material.
The beneficial effects of the utility model are, this pier anticollision composite material intercepting system is around in the periphery of bridge pier, and with bridge pier, there is a segment distance, when boats and ships are gradually near bridge pier, when having the trend of clashing into upper bridge pier, boats and ships can be tackled in time, slow down the speed of a ship or plane of boats and ships and change the navigation channel of boats and ships, prevent boats and ships from contacting with bridge pier as far as possible, at utmost can reduce the injury that large-tonnage ships causes bridge pier; Composite material buoyancy aid corrosion resistance is strong, long service life, and long-time use can not reduce crashworthiness, and structure is simple, and materials are few, conveniently install enforcement.
