Abstract
The invention discloses wave flowing force reducing type bridge pier anticollision equipment, which comprises a steel framework and a steel plate, wherein the framework comprises an inner side plate, an outer side plate, a platform plate, a bottom plate and a deck, the inner side plate is in contact with a bridge pier bearing platform, the outer side plate is parallel to the inner side plate, the platform plate is connected between the inner side plate and the outer side plate, the bottom plate and the deck are mutually parallel, the bottom plate is connected with the lower end of the inner side plate, the deck is connected with the upper end of the inner side plate, in addition, the bottom plate and the deck plate are shorter than the platform plate, the steel plate is arranged on the framework in a surrounding way, a box body structure with the rectangular tail longitudinal cross section and the trapezoidal head longitudinal cross section is formed, and a plurality of wave reducing holes are uniformly formed in the box body structure. The wave flowing force reducing type bridge pier anticollision equipment has the advantages that the anticollision energy dissipation function is reliable, the service life is long, and the maintenance and the repair are convenient; under the conditions of great wind waves, great tidal difference, higher flow rate and great possibly suffered impact force, the boat collision energy dissipation performance cannot be obviously changed, in addition, the wave impact force is reduced, and the wave flowing force borne by a bridge pier is effectively controlled.
Description
Technical field
The present invention relates to pier anticollision technical field, relate in particular to a kind of wave current power and subdue type pier anticollision equipment.
Background technology
The anti-collision structure of Oversea bridge bridge pier is pier anticollision energy dissipating safeguard measure, because bridge spanning the sea waters hydrologic condition is complicated, stormy waves is large, tidal range is large, flow velocity is higher, the wave current power that bridge pier and anti-collision structure thereof bear is suitable with pier footing horizontal force resistant, and anti-collision structure can obviously increase the wave current power that bear on basis, therefore the anti-collision structure of the Oversea bridge bridge pier in the larger waters of stormy waves need to carry out special research and design, the impact of pier footing wave current power load is controlled to zone of reasonableness when meeting anticollision energy eliminating function, and improve self survival ability and durability.
Summary of the invention
Based on this, for above-mentioned technical problem, provide a kind of wave current power to subdue type pier anticollision equipment.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of wave current power is subdued type pier anticollision equipment, the skeleton and the steel plate that comprise steel, described skeleton comprises the interior plate contacting with pier cap, the outer panel parallel with described interior plate, be connected in the landing slab between described interior plate and outer panel, and the base plate being parallel to each other and deck, described base plate is connected with the lower end of described interior plate, described deck is connected with the upper end of described interior plate, and described base plate and deck are shorter than described landing slab, described steel plate is located on described skeleton, forming afterbody longitudinal section is rectangle, head longitudinal section is trapezoidal body structure, on described body structure, be evenly provided with a plurality of wave absorptions hole.
This programme also comprises puts case, described in put the outside that case is located at described interior plate upper end.
The middle part of described outer panel is provided with energy dissipating and protects string.
The outside of described interior plate is provided with rubber strip.
On described interior plate, outer panel, landing slab, base plate, deck and steel plate, be equipped with wave absorption hole.
Anticollision energy eliminating reliable in function of the present invention, long service life, is convenient to maintenance and repair; , tidal range large at stormy waves is large, flow velocity is higher, may suffer in situation that wave impact force is larger, and the performance that ship hits energy dissipating significant change can not occur, and the impact force of wave obtained reducing, and has effectively controlled the wave current power that bridge pier bears.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is elaborated:
Fig. 1 is cross-sectional view of the present invention.
The specific embodiment
As shown in Figure 1, a kind of wave current power is subdued type pier anticollision equipment, comprises skeleton 110, the steel plate 120 of steel and puts case 130.
Adopt steel material stable performance, when basis weight materials is damaged energy dissipating large, the life-span is long, can stand the long-term impact of tidewater and the corrosion of seawater, and be convenient to maintenance and repair.
Skeleton 110 comprises with the interior plate 111 of pier cap 2 contact, the outer panel 112 parallel with interior plate 111, is connected in the landing slab 113 between interior plate 111 and outer panel 112 and the base plate 114 being parallel to each other and deck 115.
Base plate 114 is connected with the lower end of interior plate 111, and deck 115 is connected with the upper end of interior plate 111, and base plate 114 and deck 115 are shorter than landing slab 113.
What wherein, interior plate 111 can be direct or indirect is arranged on pier cap 2.
The outside of interior plate 111 is provided with rubber strip 116, and interior plate 111 is indirectly contacted with pier cap 2 through rubber strip 116, improves the contact performance of present device and pier cap 2.
The middle part of outer panel 112 is provided with energy dissipating and protects string 117, in order to shock-damping energy-dissipating, can adopt rubber to protect string.
Steel plate 120 is located on skeleton 110, forming afterbody longitudinal section is that rectangle, head longitudinal section are trapezoidal body structure, this similar fusiform profile is clashed in the process of this body structure wave, current can change direction, and the resistance that this profile is subject in fluid is less, relative minimizing the impact force of wave.
On above-mentioned body structure, be evenly provided with a plurality of wave absorptions hole 140, when water level is lower, the slamming power of wave can be obviously reduced in wave absorption hole 140.
Particularly, on interior plate 111, outer panel 112, landing slab 113, base plate 114, deck 115 and steel plate 120, all offer wave absorption hole 140.
Put case 130 and be located at the outside of interior plate 111 upper ends, can equipment be fixed on pier cap 2 by putting case 130, certainly, also can fix by other means.
But, those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, and be not used as limitation of the invention, as long as within the scope of connotation of the present invention, to the variation of the above embodiment, modification, all will drop within the scope of claims of the present invention.
