Abstract
Have a pier anticollision device, collision-prevention device for dispersing impact forces function, described anticollision device, collision-prevention device comprises anti-collision body and some support columns; Described anti-collision body is enclosed in bridge pier outside, described support column is supported between bridge pier and anti-collision body, support column comprises end and is connected and the support bar one be fixed on anti-collision body and support bar two, support bar one and support bar two afterbody are all fixed on bridge pier, form triangular structure with abutment surface, and support bar two is positioned at immediately below support bar one.The present invention is provided with support column between anti-collision body and bridge pier, not only the impact of boats and ships can be dispersed into along support column one and the power supporting two directions, and support column one and support two triangles formed with abutment surface there is good stability, intensity and the shock-absorbing capacity of device can be improved further, avoid the damage of bridge pier.
Description
Technical field
The present invention relates to anti-collision bridge pier field, especially a kind of anticollision device of pier with disperses impact forces function.
Background technology
Along with the fast development of transportation, the large bridge quantity in leap that China builds in the recent period navigation rivers, port district and straits progressively increases, and ships quantity on navigation channel also constantly increases and ship type is tending towards in maximization, make the contradiction between bridge and current boats and ships increasingly outstanding, therefore the accident of ship collision bridge pier also constantly increases.The structural damage that the shock of boats and ships to bridge causes reduces the supporting capacity of bridge within projected life and durability to a certain extent, even can cause collapsing of total.
In prior art, the anti-collision structure of bridge pier adopts reinforced composite sandwich to reach the effect of buffering energy-absorbing usually, and impact reduces fast until disappear, thus protection bridge pier and even bridge.This reinforced composite sandwich is generally all wrapped at bridge pier outer wall, and due to ship impact force all vertical with bridge pier body, this set can only play certain cushioning effect in the reinforced composite sandwich of bridge pier periphery, effectively can not disperse the impact force of boats and ships, boats and ships to the impact force of bridge pier completely perpendicular to bridge pier, in today that boats and ships more and more maximize, conventional crash structure is adopted to be difficult to ensure the safety of bridge pier.
Summary of the invention
The technical problem to be solved in the present invention is: overcome conventional crash structure in prior art and effectively can not carry out the deficiency of effectively dispersion to ship shock power, provide a kind of anticollision device of pier with dispersing impact forces function.
The technical solution adopted for the present invention to solve the technical problems is: a kind of anticollision device of pier with dispersing impact forces function, and described anticollision device, collision-prevention device comprises anti-collision body and some support columns; Described anti-collision body is enclosed in bridge pier outside, described support column is supported between bridge pier and anti-collision body, support column comprises end and is connected and the support bar one be fixed on anti-collision body and support bar two, support bar one and support bar two afterbody are all fixed on bridge pier, form triangular structure with abutment surface, and support bar two is positioned at immediately below support bar one.
Further, for improving the enabling capabilities of support column, described support column is steel concrete cylinder or metal column or is reinforced concrete floor coated metal rod structure.
Further, described anti-collision body is layer structure, and described anti-collision body is layer structure, the encapsulant layer comprising outer ring, inner ring and be filled between outer ring and inner ring.
As preferably, for enabling crashproof body have higher intensity, described outer ring is fiber reinforced plastic barrel, and described inner ring is metal cylinder or steel concrete cylindrical shell.
As preferably, for improving the buffering energy-absorbing function of anti-collision body further, the buffer board that described encapsulant layer comprises buffering energy-absorbing material and is supported between inner ring and outer ring.
The invention has the beneficial effects as follows, the present invention is provided with support column between anti-collision body and bridge pier, not only the impact of boats and ships can be dispersed into along support column one and the power supporting two directions, and support column one and support two triangles formed with abutment surface there is good stability, intensity and the shock-absorbing capacity of device can be improved further, avoid the damage of bridge pier.
