Abstract
The present invention relates to aquatic building technical field of safety protection, especially a kind of bridge pier anti-collision protective device, comprise uniform ring around the protection post be fixed on around bridge pier, the center line of protection post and the axis being parallel of bridge pier, the cross section of protection post is triangular in shape, forms the groove of inverted triangle between adjacent protection post, bridge pier outer ring is also equipped with multiple cylindrical tube, each cylindrical tube is embedded in the groove of corresponding inverted triangle, and between connected by rope, form one-level guard ring.The present invention is by first forming one-level guard ring around the many cylindrical tube arranged; bridge pier is when being subject to clashing into; first through the shock of one-level guard ring, first order power consumption is carried out, if after the long-time service failure of one-level guard ring; also has the secondary guard ring that triangle protection post is formed; secondary energy consumption can be carried out to shock, after multistage like this power consumption, can will arrive very low scope by the shock of bridge pier; advantageously protect bridge pier, strengthen the steadiness of bridge.
Description
Technical field
The present invention relates to aquatic building technical field of safety protection, especially a kind of bridge pier anti-collision protective device.
Background technology
Ship (car) hits bridge accident and is constantly occurring all over the world always, the frequency of vessel bump bridge accident more than we imagine higher.The casualties caused by vessel bump bridge accident, property loss and environmental disruption are surprising.A lot of vessel bump bridge accident gently then loses tens thousand of unit, heavy then casualties, loses in millions of, tens million of even multi-million dollar, and a large amount of indirect losses is difficult to calculate especially.Therefore take crashproof safeguard procedures particularly necessary to bridge, its basic goal is: prevent bridge chance boats and ships (vehicle) impact and recurring structure damages, protect boats and ships (vehicle) as much as possible simultaneously, loss be reduced to a minimum.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the technical problem of the crashproof heterodyne that existing anticollision device of pier exists, the invention provides a kind of bridge pier anti-collision protective device.
The technical solution adopted for the present invention to solve the technical problems is: a kind of bridge pier anti-collision protective device, comprise uniform ring around the protection post be fixed on around bridge pier, the center line of described protection post and the axis being parallel of bridge pier, the cross section of protection post is triangular in shape, form the groove of inverted triangle between adjacent protection post, bridge pier outer ring is also equipped with multiple cylindrical tube, and each cylindrical tube is embedded in the groove of corresponding inverted triangle, and connected by rope between adjacent column pipe, form one-level guard ring.
In order to play cushioning effect, described protection post is hollow-core construction, and its inside is filled with polyurethane foam, glass fiber, carbon fiber, aramid fiber or composite fibre.
In order to strengthen the intensity of rope, prevent fracture, it is twisted shape structure that described rope twists with the fingers stock by multiply wire rope core, and wire rope core is that to twist with the fingers the coated many polyethylene fibre silks of stock be outward twisted shape structure to steel cable.
In order to play cushioning effect further, the outer ring of described cylindrical tube is coated with rubber layer.
In order to avoid wearing and tearing rope, the cross section of described protection post is isosceles triangle, and what fit with bridge pier is base, and A place, its summit is arc transition.
The invention has the beneficial effects as follows; bridge pier anti-collision protective device of the present invention; by first forming one-level guard ring around the many cylindrical tube arranged; bridge pier is when being subject to clashing into; first through the shock of one-level guard ring; carry out first order power consumption; if after the long-time service failure of one-level guard ring; also has the secondary guard ring that triangle protection post is formed; secondary energy consumption can be carried out to shock, after multistage like this power consumption, can will arrive very low scope by the shock of bridge pier; advantageously protect bridge pier, strengthen the steadiness of bridge.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
In figure: 1, bridge pier, 2, protection post, 3, cylindrical tube, 4, rope.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1, embodiments of the invention, a kind of bridge pier anti-collision protective device, comprise uniform ring around the protection post 2 be fixed on around bridge pier 1, the center line of protection post 2 and the axis being parallel of bridge pier 1, the cross section of protection post 2 is triangular in shape, the groove of inverted triangle is formed between adjacent protection post 2, bridge pier 1 outer ring is also equipped with multiple cylindrical tube 3, each cylindrical tube 3 is embedded in (cylindrical tube 3 is partly embedded in the groove of inverted triangle) in the groove of corresponding inverted triangle, and connected by rope 4 between adjacent column pipe 3, form one-level guard ring.Protection post 2 is hollow-core construction, and its inside is filled with polyurethane foam, glass fiber, carbon fiber, aramid fiber or composite fibre.It is twisted shape structure that rope 4 twists with the fingers stock by multiply wire rope core, and wire rope core is that to twist with the fingers the coated many polyethylene fibre silks of stock be outward twisted shape structure to steel cable.The outer ring of cylindrical tube 3 is coated with rubber layer.The cross section of protection post 2 is isosceles triangle, and what fit with bridge pier 1 is base, and A place, its summit is arc transition.
The bridge pier anti-collision protective device of the present embodiment; by around arrange many cylindrical tube 3 first form one-level guard ring, bridge pier when being subject to clashing into, first through the shock of one-level guard ring; carry out first order power consumption; if after the long-time service failure of one-level guard ring, the secondary guard ring also having triangle protection post 3 to be formed, can carry out secondary energy consumption to shock; after multistage like this power consumption; can by the shock of bridge pier by very low scope, advantageously protect bridge pier, strengthen the steadiness of bridge.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on manual, must determine its technical scope according to right.
