Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1, soft ground is abandoned quarrel high roadbed piece of smooth land solid concrete roabed road structure and is comprised: loaded filter 10, is arranged on bottom cheuch filling body; Soft ground filling body 20, placement in layers impact compaction are at loaded filter 10 top; Impervious barrier 30, is arranged on soft ground filling body 20 top; Drainage channel 40, in length and breadth to being disposed on bottom soft ground filling body 20 top and impervious barrier 30; Piece of smooth land surface structure 50, is arranged on impervious barrier 30 top; Solid concrete roabed 60, is arranged on piece of smooth land surface structure 50 top; Waterproofing course 70, is arranged on piece of smooth land surface structure 50 top at solid concrete roabed 60 two ends.
With reference to Fig. 1, the utility model utilizes the loaded filter 10 being arranged on ditch valley portions to discharge the underground water of cheuch, and avoid soft ground softening under groundwater effect, weaken stability is not enough and sedimentation occurs; Utilize placement in layers and the soft ground filling body 20 of impact compaction as a whole railway roadbed 60 fill supporter, solve good filler deficiency problem and reduce excavation abandon quarrel stack difficulty problem, greatly can save construction investment.Utilize impervious barrier 30 the surface water isolation more than piece of smooth land, avoid it to enter in soft ground filling body 20, make its weaken and under the effect of water, new sedimentation occurs.Drainage channel 40 is utilized to discharge the lower infiltration of impervious barrier 30 isolation.Utilize piece of smooth land surface structure 50 as a whole railway roadbed 60 sclerosis basis, under making High-speed Train Loads, it has larger rigidity, and controlled elastic deformation only occurs.Utilize the surface protection water layer of waterproofing course 70 railway roadbed 60 two ends piece of smooth land surface structure 50 as a whole, ooze under avoiding the surface water.
With reference to Fig. 2, described soft ground filling body 20 construction period arranges geotextiles 80 at its top, and arranges surcharge preloading filling body 90 at geotextiles 80 top.Surcharge preloading filling body 90 filled height should exceed the conversion earth pillar height of piece of smooth land surface structure 50, solid concrete roabed 60 and top train load, and the surcharge preloading time must to soft ground filling body 20 settlement stability.Utilize geotextiles 80 to isolate soft ground filling body 20 and the top surcharge preloading filling body 90 of construction period, avoid affecting soft ground filling body 20 when excavating top surcharge preloading filling body 90.The sedimentation utilizing top surcharge preloading filling body 90 to accelerate soft ground filling body 20 completes, and excessive relative settlement occurs soft ground filling body 20 after avoiding solid concrete roabed 60 to construct and under the High-speed Train Loads of top.
The utility model effectively solves and adopts soft ground to fill the large-scale piece of smooth land to lay solid concrete roabed problem, has that easy construction, relative settlement are little, economic dispatch feature, has wide popularizing application prospect.
With reference to Fig. 1, described loaded filter 10 can adopt hard rock shiver stone to fill, and its thickness is not less than 1.0m, has and is not less than the drainage grade of 3 ‰ and unobstructed drain outlet.Described soft ground filling body 20 adopts the soft ground placement in layers compacting in excavation, and adopts strong rammer to chase after close compacting every 5 ~ 8m.Described drainage channel 40 adopts in steel concrete ditch and fills clean crushed stone, is not less than 2 ‰ in length and breadth to drainage grade.Described piece of smooth land surface structure 50 adopts graded broken stone water mixing mud to fill, cement mixing content general 3% ~ 5%, and thickness is 0.4 ~ 0.6m.Described solid concrete roabed 60 is made by steel concrete, arranges one shrinkage joint every 20 ~ 30m.Described waterproofing course 70 adopts asphalt concrete structure, and its thickness is generally not less than 8cm.
With reference to Fig. 3, described impervious barrier 30 is made up of medium coarse sand bottom 31, composite water drain-proof plate 32 and medium coarse sand top layer 33, and the thickness of medium coarse sand bottom (31) and medium coarse sand top layer (33) is generally 0.2m.
With reference to Fig. 1, Fig. 2, sequence of construction of the present utility model is: soft ground filling body 20 settlement stability of the loaded filter 10 → placement in layers of construction ditch valley portions impact compaction soft ground filling body → construction geotextiles 80 → construction top surcharge preloading filling body 90 → treat → excavate top surcharge preloading filling body 90 → construction drainage passage 40 → Construction Anti-seepage layer 30 → construction piece of smooth land surface structure 50 → solid concrete roabed 60 → construction waterproof layer 70 of constructing.
The above principle more of the present utility model that just explain through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the utility model is applied for.
