Abstract
The utility model relates to a quake-proof flood-fighting half integration type bridge abutment seamless bridge with a miniature pile energy consumption system. The quake-proof flood-fighting half integration type bridge abutment seamless bridge is composed of a half integration type bridge abutment bridge girder, the miniature pile energy consumption system and a bridge floor system which are respectively located at two ends of a bridgehead, wherein the miniature pile energy consumption system comprises a miniature pile, a sleeper beam located at the top of the miniature pile, a bridge floor extension connecting plate and a butt strap, and the half integration type bridge abutment bridge girder is connected with the miniature pile energy consumption system into a whole through the connecting plate to form the quake-proof flood-fighting half integration type bridge abutment seamless bridge. According to the quake-proof flood-fighting half integration type bridge abutment seamless bridge with the miniature pile energy consumption system, the miniature pile energy consumption system is located at the bridgehead, and therefore quake-proof performance and flood-fighting performance of the bridge girder are effectively improved. By means of a miniature pile vertical bearing system arranged under the bridge girder and the transition of the connecting plate and the butt strap among bearing objects with different stiffness, the bridge girder can achieve unobvious settlement, and is free from harmful seams and maintenance.
Description
Technical field
The utility model relates to a kind of seamless bridge of antidetonation flood fighting type semi-monolithic formula abutment with mini pile power consumption system, be suitable for China earthquake protection district, because it not only can adopt pile foundation (to newly-built or old bridge), and can eliminate the sedimentation that the platform rear region causes by horizontal cyclic temperature deformation and road surface load and have stronger shock resistance.
Background technology
China is the country of earthquake more than, and seismic activity is frequent, and earthquake magnitude is strong.Seismic activity mainly is distributed in the areas such as southwest, northwest, south China and the Taiwan Straits; Simultaneously, China's most area is in flood threat district.These local bridges distribute more again; Therefore new bridge design and the old bridge transformation of Anti-seismic, high-durability and few maintenance workload are shouldered heavy responsibilities, select bridge rational, science very crucial.China's most area is the earthquake protection district, this just requires the bridge in the road lifeline engineering of Design ﹠ reform, when accomplishing seamless process, have again the ability of opposing extreme environment load action, thereby make bridge have good workability, economy, durability and safety.This seamless bridge of antidetonation flood fighting type semi-monolithic formula with mini pile power consumption system is through Semi-Integral Abutment Jointless Bridge beam good, rationally integral seamless design, can satisfy simultaneously above requirement, thereby also have good application prospect.
Summary of the invention
The purpose of this utility model is many earthquake protection district and/or flooding district for China, a kind of novel seamless bridge of antidetonation flood fighting type semi-monolithic formula abutment with mini pile power consumption system is proposed, by the end of the bridge at conventional semi-monolithic formula abutment bridge mini pile power consumption system is set and improves its combination property, thus the seamless bridge of Antiseismic flood-resistant type semi-monolithic formula abutment that is able to meet design requirement.
The technical solution of the utility model is: a kind of seamless bridge of antidetonation flood fighting type semi-monolithic formula abutment with mini pile power consumption system, it is characterized in that: the seamless bridge of this antidetonation flood fighting type semi-monolithic formula abutment is by semi-monolithic formula abutment bridge, the mini pile power consumption system and the bridge deck that are positioned at the end of the bridge two ends form, described mini pile power consumption system comprises mini pile 7, be positioned at the sleeper beam 3 at mini pile top, bridge floor extends junction plate 2 and attachment strap 4, described semi-monolithic formula abutment bridge and mini pile power consumption system are linked to be an integral body through junction plate 2, form the seamless bridge of this antidetonation flood fighting type semi-monolithic formula abutment.
Above-mentioned semi-monolithic formula abutment bridge comprises the continuous girder of structure 1, semi-monolithic formula abutment 5, conventional bearing 8 and is positioned at concrete pile foundation 6 under the abutment.
Owing to taking above-mentioned improvement form of structure, the utlity model has following good characteristics:
1. the seamless bridge of this novel semi-monolithic formula abutment has improved anti-seismic performance and the anti-flood capacity of bridge effectively by mini pile power consumption system is set at end of the bridge;
2. this novel seamless bridge has been integrated the advantage of semi-monolithic formula abutment and Integral Abutment Bridge, has really realized road and bridge integral seamless connection, is particularly suitable for the national conditions of China.This bridges can be widely used in China mostly new bridge construction and the strengthening and rehabilitation of old bridges earthquake region, a large amount of wide Middle Or Small Span footpaths of face.The vertical bearing system of mini pile and the junction plate between the different-stiffness support and the transition of attachment strap that this novel seamless bridge is divided into by sleeper beam can make bridge really accomplish without obviously sedimentation, protect without harmful cracks and zero dimension.
Description of drawings
Fig. 1 is the seamless bridge construction schematic diagram of antidetonation flood fighting type semi-monolithic formula abutment among the embodiment.
Among the figure: 1 girder, 2 junction plates, 3 sleeper beams, 4 attachment straps, 5 semi-monolithic formula abutments, 6 concrete pile foundations, 7 mini piles, 8 conventional bearing 9 bridge decks.
The specific embodiment
Below in conjunction with accompanying drawing and an embodiment the utility model is described further, separate application of the present utility model with the assistant, but protection domain of the present utility model is not limited to this instantiation.
As shown in Figure 1, this is comprised of semi-monolithic formula abutment bridge, the mini pile power consumption system and the bridge deck 9 that are positioned at the end of the bridge two ends with the seamless bridge of antidetonation flood fighting type semi-monolithic formula abutment of mini pile power consumption system.Mini pile power consumption system comprises mini pile 7, is positioned at the sleeper beam 3 at mini pile 7 tops, bridge floor extends junction plate 2 and attachment strap 4, described semi-monolithic formula abutment bridge and mini pile power consumption system are linked to be an integral body through junction plate 2, form the seamless bridge of this antidetonation flood fighting type semi-monolithic formula abutment.
Above-mentioned semi-monolithic formula abutment bridge comprises the continuous girder of structure 1, semi-monolithic formula abutment 5, conventional bearing 8 and is positioned at concrete pile foundation 6 under the abutment
When earthquake occured, the mini pile dissipative system can be received a large amount of seismic forcess, partly directly seismic energy was diffused in the soil of mini pile 7 perimembranous, had reduced so widely the effect of earthquake to the body of a bridge.And normally brisance is directly born by bridge.Simultaneously, the continuous girder 1 of the structure of this bridges is connected with bridge deck effectively to be connected with attachment strap with junction plate 2, sleeper beam 3 and is connected in aggregatesly, realizes that really road and bridge are integrated, and can effectively resist horizontal flood impact force.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
