Description

Anti-impacting bearing pile for bridge

Technical field

The present invention relates to a kind of bridge-collision-avoidance facility, particularly a kind of for avoiding or alleviate boats and ships and bridge pier bumps, and the anti-impacting bearing pile for bridge that colliding vessel oceangoing ship energy dissipating buffering is used.

Background technology

Because economy and communication is flourish; the bridge that sets up on the navigation channel of navigation is more and more; also increasing; the over strait of overlength or the even appearance of island bridge are more arranged; make that original navigation channel diminishes, stenosis; so not only many tons from thousands of to tens thousand of that also maximize of the ship on the navigation channel meanwhile are on the newspaper or TV in the whole world, about the incident of ship collision bridge pier happens occasionally and reports.Some little collisions also can be repaired, in case it is hardly imaginable that big its consequence of collision takes place, not impaired for making the safety of navigating, bridge, people have taked a lot of ways and facility to protect the bridge construction thing.

Patent No. CN99236972.X " pier anticollision protective device "; this device is that direct holding-solid is used on bridge pier; allowing ship impinge upon this device goes up with the spring on it the ship fender effect that rebounded; first impact is still directly born by bridge pier, and this device only suits to use on less bridge pier in addition.

Its one group of protective device of the number of patent application CN200510029901.4 protective device of bridge pier " navigate bump " is by the fixed component on being arranged on around the bridge pier; be arranged on the cushion between fixed component and bridge pier; be fixed on the track of filling ball bearing on the fixed component and be bonded in; protection skin between lower railway on the bridge pier wall is formed; at first this device remains and directly is fixed on the bridge pier; the ball that is hit is rolled on the protection skin of bridge pier; this also only is a perfect condition; in fact it is very little of protecting skin to make the bridge pier surface deformation be difficult to rotate to be hit the ball volume again; bridge pier also is to bear the initial impact of ship; so this device is to the impact of bridge pier and the buffering of energy; it is also very limited that branch is led effect, DeGrain.

Its ball is that string rolls on an axle and between two closed slides in addition, and the power of at this moment being hit must just can be rotated with axle by ball on the position, power center (PC) of axle, and obviously this is again a kind of ideal, imaginary state.In fact if stress point is more crooked, whole axle will stuckly can't be moved in track at all, let alone rotated, and two parallel orbits are fixed on the bridge pier simultaneously, if there is foreign matter to fall into track, the possibility that balance is slided is just very little.

Very big because of bridge pier again; and every group of protective device all will be installed two parallel orbits on bridge pier; so long track alignment error is wayward; the flexibility that the ball axle rotates will directly be influenced; can not occur over just on the water surface because of colliding; also there is the collision of ship itself and the bridge pier of submarine and ball nose shape all to occur under water; bridge also is subjected to the influence of rising tide, ebb in addition; so need on the very big area in bridge pier surface, to install a lot of group protective devices; subaqueous construction simultaneously also needs the diver to operate; the difficult control of installation accuracy, maintenance is difficulty also.

Summary of the invention

Technical problem to be solved by this invention is: a kind of anti-impacting bearing pile for bridge is provided, the course that makes it can carry out the energy dissipating buffering to the boats and ships of collision and effectively guide boats and ships, and make boats and ships can not directly clash into bridge pier, both reduced the infringement of boats and ships, reduced the damage of boats and ships self again bridge pier.

The present invention addresses the above problem the technical scheme that is adopted: the fender stake is by rotating fender and packing ring more than one and one are being installed in the stake, at the foot of stake one locating ring being installed forms, described fender stake connects into whole stake battle array with connector between each, is built in along on the forward and backward position of direction along ng a path bridge pier.

Compared with prior art, the invention has the advantages that: 1, this is built on the forward and backward position of bridge pier, do not contact with bridge pier, boats and ships directly do not clash into bridge pier, be to protect bridge pier and boats and ships not to be damaged as cost to sacrifice the fender stake, because of the fender stake can be reconstructed after damaging, but the cost of bridge pier, boat damage is just hardly imaginable; 2, to be hit all be to hit or lean on bridge pier in this fender stake, the impact of this moment has not been all to be added in having gone up against point of rum point and bridge pier, mud during because of bump under the stake also plays cushioning effect, bear and weakened a part of impact, the speed of a ship or plane reduces few because the fender rotation makes the ship course change, Impact energy is just little, and it is enough with regard to reducing for the suffered impact of ship and bridge pier, so this really plays the effect of energy dissipating buffering; 3, this fender stake has triple protection, plays the effect that weakens impact gradually, and general bump can both withstand, make the damaged condition of boats and ships reduce to minimum, can effectively guide the course of boats and ships simultaneously again, play four liang and pull out very heavy effect, big to the pier anticollision protective effect, crashproof effective; 4, this fender stake is easily processed, easily installation, fender are easily changed, and requirement on machining accuracy is low.

The specific embodiment

Below in conjunction with accompanying drawing embodiments of the invention are further described.

Fender 4 annular for making with elastomeric material, the proportion of fender makes it can produce certain buoyancy preferably less than water, always to come-up, or makes full use of old tire and fills the tire bar and make in water.

It is more flexible for fender 4 is rotated in stake 1, load onto L shaped neck bush 2, the external bushing of making of plastic cement 5 at itself and 1 of stake, and the thickness of inside and outside lining is by the fit clearance decision of 1 of the internal diameter of fender 4 and stake, also inside and outside lining and fender 4 are connected into the integral body that fender can rotate around

stake

1, and 4 of each fenders also are equipped with plastic washers 6 with bolt, nut 3.

Stake 1 has been made in water when bridge construction for pile tube, or construction can again behind bridge construction.

The fender integral body that the one or more fender 4 that is connected with packing ring 6, inside and

outside lining

2,5 is constituted is enclosed within respectively in each stake 1, according to crashproof ship draft be set to always under water the stake 1 on, for making fender 4 location, in the end under a fender locating ring 8 is housed also, and meet the place at locating ring two halves tower, use the bolt, the nut that are made into through metal that surface anticorrosive is handled or plastic cement to be fixed on and constitute

fender stake
