Abstract
The utility model relates to the technical field of water building safety protection, particularly to a pier anti-collision protective device which comprises protective columns fixed on the periphery of the pier in a uniform surrounding manner, wherein the central line of each of the protective columns is parallel to the axis of the pier; the cross section of each of the protective columns takes the shape of a triangle; an inverted triangle groove is formed between every two adjacent protective columns; multiple cylindrical pipes are further arranged on the periphery of the pier in a surrounding manner; the cylindrical pipes are embedded in corresponding inverted triangle grooves and connected through ropes to form a primary protective ring. According to the utility model, the multiple cylindrical pipes arranged in a surrounding manner firstly form the primary protective ring, when the pier is collided, the first-level energy consumption is performed firstly through the collision born by the primary protective ring, if the primary protective ring is damaged after long-term use, the triangle protective columns can form a secondary protective ring to perform second-level energy consumption on the collision, and after several energy consumption, the collision to the pier can be reduced to be in a quite small range, so that the pier is favorably protected, and the stability of a bridge is enhanced.
Description
Technical field
The utility model relates to aquatic building safety protection technique field, especially a kind of bridge pier crashworthiness protector.
Background technology
Ship (car) hits bridge accident and is constantly occurring all over the world always, and the frequency that ship hits bridge accident is higher more than our imagination.It is surprising hitting by ship casualties, property loss and the environmental disruption that bridge accident causes.A lot of ships hit bridge accident and gently lose tens thousand of units, and heavy casualties is lost in millions of, tens million of even multi-million dollars, 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 breaking-up, the while is protected boats and ships (vehicle) as much as possible, and loss is reduced to a minimum.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the technical problem of the crashproof heterodyne that existing anticollision device of pier exists, the utility model provides a kind of bridge pier crashworthiness protector.
The utility model solves the technical scheme that its technical problem adopts: a kind of bridge pier crashworthiness protector, comprise that uniform ring is around being fixed on bridge pier protection post around, the center line of described protection post is parallel with the axis of bridge pier, the cross section of protection post is triangular in shape, between adjacent protection post, form the groove of inverted triangle, 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 between connect by rope, 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, described rope is twisted with the fingers thigh by multiply wire rope core and is twisted shape structure, and wire rope core is that steel cable is twisted with the fingers strand coated many polyethylene fibre silks outward and is twisted shape structure.
In order further to play cushioning effect, the outer ring of described cylindrical tube is coated with rubber layer.
For fear of wearing and tearing rope, the cross section of described protection post is isosceles triangle, and the one side of fitting with bridge pier is base, and A place, its summit is arc transition.
The beneficial effects of the utility model are; bridge pier crashworthiness protector of the present utility model; by first forming one-level guard ring around many cylindrical tube that arrange; bridge pier is in the time being subject to clashing into; first pass 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 that also has triangle protection post to form; can carry out secondary energy consumption to clashing into, after multistage like this power consumption, can will will arrive very low scope to the shock of bridge pier; advantageously protect bridge pier, strengthened the steadiness of bridge.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, bridge pier, 2, protection post, 3, cylindrical tube, 4, rope.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, embodiment of the present utility model, a kind of bridge pier crashworthiness protector, comprise that uniform ring is around being fixed on bridge pier 1 protection post 2 around, the center line of protection post 2 is parallel with the axis of bridge pier 1, the cross section of protection post 2 is triangular in shape, between adjacent protection post 2, form the groove of inverted triangle, bridge pier 1 outer ring is also equipped with multiple cylindrical tube 3, each cylindrical tube 3 is embedded in the groove interior (cylindrical tube 3 is to be partly embedded in the groove of inverted triangle) of corresponding inverted triangle, and between connect by rope 4, 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.Rope 4 is twisted with the fingers thigh by multiply wire rope core and is twisted shape structure, and wire rope core is that steel cable is twisted with the fingers strand coated many polyethylene fibre silks outward and is twisted shape structure.The outer ring of cylindrical tube 3 is coated with rubber layer.The cross section of protection post 2 is isosceles triangle, and the one side of fitting with bridge pier 1 is base, and A place, its summit is arc transition.
The bridge pier crashworthiness protector of the present embodiment; by first forming one-level guard ring around the many cylindrical tube 3 that arrange, bridge pier, in the time being subject to clashing into, first passes 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 that also has triangle protection post 3 to form, can carry out secondary energy consumption to clashing into; after multistage like this power consumption; can by the shock of bridge pier by very low scope, advantageously protected bridge pier, strengthen the steadiness of bridge.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to claim scope.
