Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
As shown in Figures 1 to 4, a kind of high embankment filled soil end of the bridge anti-settling structure, comprises abutment, piling strtucture 12, road surface structare layer 1, attachment strap deck 2 and base course 5.
Described road surface structare layer 1 designs according to category of roads, be generally coarse grain formula pitch+middle grain formula pitch+stone mastic asphalt, grain formula bituminous concrete (AC-20C)+40mm stone mastic asphalt SMA-13 (SBS modification) in (from bottom to top) 6mm slurry seal+80mm Coarse Graded Bituminous Concrete (AC-25C)+60mm can be designed to.Road surface structare layer 1 is laid on attachment strap deck 2,
Described attachment strap deck 2 comprises attachment strap, is provided with longitudinal reinforcement 14 and transverse reinforcement 15 in this attachment strap, and to strengthen the intensity of attachment strap, below attachment strap, interval arranges piling strtucture 12, and the part be positioned in attachment strap above piling strtucture 12 is provided with diagonal bar 13 reinforcement attachment strap.The head of described attachment strap is set up on abutment bracket 11, reserved plastic flexible pipe 8 in attachment strap, pre-doweling 10 in Abutment Back, makes attachment strap deck 2 and end of the bridge be articulated and connected by joint bar 10 through the asphaltic felt bed course be arranged on the bearing surface 9 of abutment bracket 11 and plastic flexible pipe 8.Concrete attachment strap length is arranged according to the depth of fill and the difference of ground situation.Be provided with gap between attachment strap deck 2 and Abutment Back 7, in this gap, clog the sealing materials such as bitumastic, play the flexible and sealing effect of buffering attachment strap deck 2.Attachment strap deck 2 can arrange polylith attachment strap according to the road surface situation that is open to traffic, and the width of attachment strap is consistent with carriageway width, and direction across bridge such as can be divided at the block plate, each attachment strap is connected by tension rib 6, be provided with settlement joint between each attachment strap, filling rubber fastening band in this settlement joint, and establish power transmission pull bar every 500mm.Attachment strap structure adopts armored concrete slab, and when attachment strap length is 6m, thickness of slab is 350mm, and when attachment strap length is more than 12m, thickness of slab is 500mm; Be provided with gap between transition slab at bridge head and Abutment Back and clog just like sealing materials such as pitch water chestnut fat in this gap, the expansion of attachment strap structure can be adapted to like this extend, avoid producing thrust to abutment parados, can prevent surface gathered water from infiltrating along gap simultaneously, band bankets after walking on stage, and avoids attachment strap lower floor to occur coming to nothing.
Described attachment strap deck sets gradually plain concrete layer 3, hardcore bed 4 for 2 times, and plain concrete layer 3 is connected with piling strtucture 12 mutually with hardcore bed 4.Pile crown place attachment strap structure 2 thickness of slab strengthens, and laterally elongated, forms transverse strut.Plain concrete layer 3 is built on hardcore bed 4.The wide each 100mm of attachment strap deck 2 going out to be positioned at bridgehead position of described plain concrete layer 3 both lateral sides, plain concrete cushion layer plays stress spread, can alleviate or eliminate the phenomenon that attachment strap far-end secondary jumps car, and surfacing when attachment strap structure is built, be convenient to attachment strap structure and evenly transmit load to roadbed.Described hardcore bed 4 is laid on base course 5, can play the effect of diffusion-induced stress when soft ground treatment, and can draining, accelerates the consolidation and settlement of bottom soil layer.The stake top of described piling strtucture 12 is arranged at middle part or the afterbody of attachment strap deck 2, and the stake top length being wherein positioned at the piling strtucture 12 at middle part is greater than the stake top length of the piling strtucture 12 of afterbody.Described base course is filled by compaction in layers of banketing after platform and forms, and adopts 8wt% rendzinas below road structure within the scope of 0.6m, and its lower employing 6wt% rendzinas, the intensity >=0.6Mpa of base course, the degree of compaction of banketing after platform should strictly control.
After said method process, the stake soil rigidity of road structure is promoted, and structure arranges from flexibility to rigidity gradual change therefore relative settlement can be made to be weakened, thus solving problem of vehicle bump at bridge head.
Although content of the present utility model has done detailed introduction by above preferred embodiment, will be appreciated that above embodiment only in order to the technical solution of the utility model to be described and unrestricted.After those skilled in the art has read foregoing description, can various amendment be made to it in the form and details and substitute, but protection domain of the present utility model should be limited to the appended claims.
