Abstract
The invention discloses a bridge foundation damping structure. The bridge foundation damping structure comprises two supporting columns, wherein a tensile reinforcing rod is installed at the position, close to the top, between the two supporting columns, the tensile reinforcing rod is formed by stranding a plurality of steel rods, two ends of the tensile reinforcing rod are respectively fixed on the supporting columns, the bottom of each supporting column is arranged on a pier, the bottom of each supporting column is embedded into the pier, a buffer member is arranged in the pier, an anti-collision plate covers the surface of the buffer member, the anti-collision plate is fixed on the pier in a sealing manner, more than one steel grating plate is arranged at the positions, close to two sides, of the lower surface of the pier, and the steel grating plates are uniformly arranged and fixed on the pier. By adopting the bridge foundation damping structure, the construction quality of the engineering can be better guaranteed, and the bearing force can be better improved; moreover, the influence of the collision on the pier can be effectively avoided, the damping performance is realized, and the service life is greatly prolonged; and moreover, more firmness in connection of parts can be realized, and the firmness is better.
Description
Technical field
The present invention relates to a kind of shock-damping structure, particularly a kind of bridge foundation shock-damping structure.
Background technology
Bridge foundation is the structure of bridge foot, directly be seated on rock or soil base, its top connects abutment, effect is ensure abutment safety and load is passed to ground, therefore, for security performance and normal use of full-bridge, require ground and basis all will have enough intensity, rigidity and resistance to overturning, make it not produce excessive horizontal displacement or differential settlement, building of bridge foundation, in whole science of bridge building, occupy an important position, and general bridge foundation cannot meet user demand.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problems referred to above, a kind of bridge foundation shock-damping structure of the construction quality that can better ensure engineering is provided.
To achieve these goals, the technical solution used in the present invention is such: bridge foundation shock-damping structure of the present invention, comprise two support columns, between two support columns, near top place, tension reinforcement bar is installed, stranded the forming of many steel bars of tension reinforcement strip adoption, tension reinforcement bar two ends are all fixed on support column, support column bottom is positioned on a bridge pier, support column bottom embeds and is arranged in bridge pier, in bridge pier, be provided with bolster, its surface is coated with Crashworthy plate, Crashworthy plate seals and is fixed on bridge pier, bridge pier lower surface is provided with steel screen near both sides place, more than one of steel screen, it is and is uniformly arranged and fixed on bridge pier.
Further, as a kind of concrete version, the built-in support steel bar of support column of the present invention.
Further, as a kind of concrete version, more than one of support steel bar of the present invention, it surrounds one columnar structured.
Further, as a kind of concrete version, tension reinforcement bar of the present invention and support column junction are provided with anti-drag anchoring part.
Further, as a kind of concrete version, bolster of the present invention adopts buffer board equipment structure.
Further, as a kind of concrete version, Crashworthy plate thickness of the present invention is at least two centimetres.
Compared with prior art, the invention has the advantages that: bridge foundation shock-damping structure of the present invention can better ensure the construction quality of engineering, can better improve the dynamics of bearing, and the impact that can effectively avoid generation collision to cause bridge pier, there is certain damping performance, greatly extended service life, and between self parts, connected more firmly, steadiness is better.
