Description
Technical field
The present invention relates to a kind of anti-collision structure waterborne, being a kind of low cost utilizing composite to manufacture anticollision device, collision-prevention device elastic, corrosion-resistant, specifically the bridge anti-collision device of composite material avoiding boats and ships (floating ice) impact disaster is built in a kind of bridge pier suitable in all kinds of bridges and cushion cap etc., (ocean) waterborne.
Background technology
Vessel bump bridge accident is being constantly occurring all over the world always, and along with the fast development of transportation, the large bridge quantity crossing over navigation rivers, port district and straits is increasing; Meanwhile, on navigation channel, ships quantity is also continuously increased and tends to maximizing so that the contradiction between bridge and navigation boats and ships is increasingly prominent. The anti-ship of bridge hits problem and also obtains the great attention about the department such as shipping management, planning and designing just gradually. Carry out relevant research both at home and abroad, it is proposed that bridge collision theory, and have devised some bridge protective equipments. The basic goal of bridge-collision-avoidance is to prevent bridge from causing structural failure because ship impact force exceedes the design bearing capacity of bridge pier on the one hand, protects boats and ships as much as possible on the other hand simultaneously, loss is minimized by. The pattern of anti-collision facility is different, and its working mechanism is just different.
Hitting in design at the anti-ship of bridge, the safety of main channel and main navigable bridge opening has obtained enough attention, but several the vessel bump bridge accidents being positioned at non-navigation bridge pier occur recent domestic respectively, expose problem. The feature of non navigable span bridge pier is: bridge pier structure is thin, self resist ship, and to hit ability poor, once meet with ship collision, very easily causes bridge is all ruined and people dies tragedy and bad social influence. At present, the crashproof research being specifically designed for non-navigation bridge pier both at home and abroad is less, there is no comparatively effective and ripe thought and method. Through PRACTICE OF DESIGN for many years; main navigable pier anticollision technology has been developing progressively ripe; the technology of main flow is to adopt the flexible floating anti-collision ring being directly installed on bridge pier; owing to having taken into full account projected angle of impact, having hit power transfer; by consuming and shifting impact force; while bridge pier is protected so that boats and ships are without being subject to obvious destruction. Owing to non-navigation self drag of bridge pier is too little, direct avoiding collision is adopted not reach the purpose protecting non-navigation bridge pier, it is necessary to seek new Research Thinking. By the comprehensive analysis to domestic and international anti-collision technique with development, in conjunction with the own characteristic of non-navigation bridge pier, research and propose novel " interception " collision-proof scheme being suitable for non-navigation bridge pier.
The theoretical foundation of floating netted intercepting system is based upon boats and ships can bigger buffer displacement, and after boats and ships are stopped by the netted interception facility of guard system, its hawser under water and keg buoy can consume on the basis of Impact energy effectively. Netted interception facility swims on the water surface, can be transferred on anchor ingot by hawser by energy, and due to this feature, floating netted guard system can be arranged in the bridge location place that navigation channel is deeper. It is crashproof that the collision-proof scheme " blocked " belongs to indirect configuration class, has the mode such as floating block CAS, buoyancy aid mooring rope CAS, the advantage with " fighting against the enemy on the frontier ". But only the mode by directly " blocking " is unable to reach pier anticollision safety requirements: one is the buffer displacement that system consumption energy demand is very long, two is that huge easily the pressing through of boats and ships kinetic energy out of control is blocked rope or break through block, still there is after energy dissipating very big impact force, still that bridge pier is dangerous.
Summary of the invention
Present invention aims to the problem that existing Direct-type anti-collision structure cost is high, weatherability is poor, reparation difficulty is big, a kind of good weatherability of design, fully absorb Impact energy, avoid the netted intercepting system of composite floatation type and the construction method of ship from colliding bridge, as bridge-collision-avoidance facility.
The technical solution used in the present invention is: a kind of netted intercepting system of composite floatation type, including main buoy, side pontoon, secondary floating drum, keg buoy, cable, anchorage, ultra-high molecular weight polyethylene nylon cable, buffering energy-consumption material, buffering energy-consumption space lattice body, concrete inner core and spar hull;
