Abstract
A pier anticollision device with the function of dispersing impact force comprises an anticollision body and a plurality of supporting columns. The anticollision body is surrounded on the outer portion of a pier, and the supporting columns are supported between the pier and the anticollision body. The supporting body comprises first supporting rods and second supporting rods, wherein the ends of the first supporting rods and the ends of the second supporting rods are connected, and the first supporting rods and the second supporting rods are fixed on the anticollision body. The tail portions of the first supporting rods and the tail portions of the second supporting rods are both fixed on the pier and form a triangle structure with the face of the pier, and the second supporting rods are placed under the first supporting rods. According to the pier anti-collision device with the function of dispersing impact force, the supporting columns are arranged between the anticollision body and the pier so that the impact force of a ship can be dispersed into force in the direction of the first supporting columns and force in the direction of the second supporting columns, the triangle formed by the first supporting columns, the second supporting columns and the face of the prier has good stability, the strength and the buffering performance of the device can be further improved, and damage to the pier is avoided.
Description
Technical field
The utility model relates to anti-collision bridge pier field, especially a kind of anticollision device of pier with dispersion impact force function.
Background technology
Along with the fast development of transportation, the large bridge quantity in leap navigation rivers, port district and straits that China builds in the recent period 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 boats and ships cause the shock of bridge has reduced supporting capacity and the durability of bridge within projected life 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 conventionally, and impact fast reducing is until disappear, thus protection bridge pier and even bridge.This reinforced composite sandwich is generally all wrapped at bridge pier outer wall, and because ship impact force is all vertical with bridge pier body, this set can only play certain cushioning effect in the reinforced composite sandwich of bridge pier periphery, can not effectively disperse the impact force of boats and ships, boats and ships to the impact force of bridge pier completely perpendicular to bridge pier, the today of more and more maximizing at boats and ships, adopt traditional anti-collision structure to be difficult to ensure the safety of bridge pier.
Utility model content
The technical problems to be solved in the utility model is: overcoming traditional anti-collision structure in prior art can not effectively carry out the deficiency of effectively disperseing to ship shock power, and a kind of anticollision device of pier that disperses impact function that has is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of have an anticollision device of pier that disperses impact 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 that end is connected and is fixed on support bar one and the support bar two on anti-collision body, support bar one and support bar two afterbodys are all fixed on bridge pier, with abutment surface form triangular structure, and support bar two be positioned at support bar one under.
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, comprise outer ring, inner ring and be filled in outer ring and inner ring between encapsulant layer.
As preferably, for making crashproof body can 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, be the buffering energy-absorbing function that further improves anti-collision body, fill in described material layer comprise buffering energy-absorbing material and be supported on inner ring and outer ring between buffer board.
The beneficial effects of the utility model are, the utility model 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 that supports two directions, and support column one and support two triangles that form with abutment surface and there is good stability, can further improve intensity and the shock-absorbing capacity of device, avoid the damage of bridge pier.
