Abstract
The utility model relate to a kind of structure receiving seamless bridge attachment strap end stress, in order to receive tension and compression pulsating stress after seamless bridge platform and to solve the problem of stress concentration of attachment strap end, in attachment strap end outsourcing one deck geotextiles and built-in elastic Energy dissipating material and build one deck absorbing energy layer.When seamless bridge is when longitudinally stretching back and forth by temperature effect, attachment strap stretching back and forth repeatedly can be driven simultaneously, by attachment strap end surrounding layer and absorbing energy layer, the attachment strap tip displacement that can temperature effect received well to produce, thus effectively reduce the roadbed subsidence of attachment strap end, avoid vehicle to produce herein and jump car phenomenon.Attachment strap near platform end is connected by connecting reinforcement entirety with girder, can receive the tension and compression pulsating stress because girder produces by temperature effect and traffic loading, effectively control the generation of deck crack herein, improve the comfortableness of driving.The utility model utilizes attachment strap end outsourcing elastic layer, builds rubber asphalt layer, and attachment strap is connected with girder entirety, thus effectively receives the stress of Integral Abutment seamless bridge changeover portion attachment strap end.
Description
Technical field
The utility model relates to a kind of structure receiving seamless bridge attachment strap end stress, is specially adapted to Integral Abutment seamless bridge, belongs to bridge field.
Background technology
Along with the fast development of auto industry, all can produce a large amount of waste and used rubber tyres every year, and in the gesture that increases year by year, according to statistics, China within 2005, produce also close to 100,000,000.How to process the waste old day by day increased, become the problem that a whole world is paid close attention to jointly.The mode of current process waste old mainly contains landfill, burning and recycling, but rubber is not easily degraded, and the pollution of landfill to environment is larger; Recycle, both can reduce environment pollution, and can economize on resources again.
Special in seamless bridge, in order to avoid arranging shrinkage joint, transition slab at bridge head is directly connected on Integral Abutment, therefore ordinary reinforced concrete attachment strap will be subject to girder and longitudinally stretch back and forth by temperature effect, can drive its stretching back and forth repeatedly simultaneously, easily cause the cracking of attachment strap near platform end bridge floor, the problem of stress concentration of attachment strap end, easily cause the sedimentation on road surface herein, cause and jump car phenomenon, reduce the comfortableness of driving.
Utility model content
In order to solve existing technical deficiency, the utility model provides a kind of structure receiving seamless bridge attachment strap end stress.
The technical solution of the utility model is:
A kind of structure receiving seamless bridge attachment strap end stress, comprise attachment strap, seamless bridge and soil matrix, it is characterized in that: described attachment strap is placed in soil matrix, and the far from the table end outsourcing geotextiles of attachment strap, place elastic dissipation energy material in described geotextiles, and this end also backfills one deck absorbing energy layer.
Wherein, described attachment strap near platform end is by the girder integrated connection of connecting reinforcement and seamless bridge.
Described elastic dissipation energy material is rubber grain, pitch.
Described absorbing energy layer is the rubber asphalt layer of one deck 20cm × 20cm × 20cm size of building outside attachment strap end outsourcing geotextiles.
The rubble that one deck does local reinforcement is backfilled under described attachment strap end and absorbing energy layer.
The utility model has the advantage of: rubber grain is used for attachment strap end by the utility model, it can absorb a large amount of vibrational energies, receive the seamless bridge displacement that attachment strap end produces under temperature effect effect, and solve the concentrated problem of attachment strap end stress, thus improve the application life of seamless bridge and transition road section surface, by connecting reinforcement by girder and attachment strap integrated connection, utilize reinforcing bar to absorb tension and compression pulsating stress, avoid the cracking of bridge floor herein, improve road-ability.

Detailed description of the invention
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
The utility model relates to a kind of structure receiving seamless bridge attachment strap end stress, comprise attachment strap, seamless bridge and soil matrix, attachment strap is placed in soil matrix, the end outsourcing geotextiles of attachment strap, in geotextiles, place elastic dissipation energy material, described attachment strap end builds one deck absorbing energy layer.
At the girder integrated connection of attachment strap near platform end by connecting reinforcement and seamless bridge, bear the tension and compression tension and compression pulsating stress that girder produces by temperature and traffic loading.
In attachment strap end outsourcing geotextiles, place the Energy dissipating material such as rubber grain, pitch, receive the displacement of attachment strap end.
Be absorbing energy layer outside attachment strap end outsourcing geotextiles, this absorbing energy layer is for building the rubber asphalt layer of one deck 20cm × 20cm × 20cm, concentrate with the stress that this weakens attachment strap end, thus reduce the impact of road pavement planeness, improve road-bridge transition section road-ability.
Under attachment strap end and absorbing energy layer, one deck rubble does local reinforcement, reduces the sedimentation of attachment strap end, improves the planeness on road surface further.
Specific implementation process:
Fig. 1 and 2 gives the structural representation of the utility model embodiment 1.In fig 1 and 2, a kind of being used for of the present embodiment receives the method for seamless bridge attachment strap near platform end tension and compression pulsating stress and end stress to be made up of attachment strap 6, abutment 4, flexible pile 5, bridge floor 1, road surface 2, girder 3, connecting reinforcement 12, sliding support 7, soil matrix 8, outsourcing elastic layer 9, absorbing energy layer 10 and macadam 11.
After removal platform embankment soil-stone material roadbed above lay the thick Base with Sand Gravel Cushion of 10cm.Base with Sand Gravel Cushion fills should at smooth location, removing foreign material, draining airing table soil, and compacting process before topsoil is filled out, fill and at least should divide two-layer carrying out, in filling, should compacting be carried out, make sand cushion degree of compaction be not less than 85%, sand material quality should meet code requirement; Pave evenly, guarantee surfacing, and backfill one deck rubble as local unreinforced layer at attachment strap end.Then colligation attachment strap reinforcing bar, concreting, when attachment strap concrete strength reaches 85%, in attachment strap end outsourcing one deck geotextiles, and built-in rubber particle, bond firmly with attachment strap.And build a 20cm × 20cm × 20cm rubber asphalt at attachment strap end, finally build road surface.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
