Abstract
A soilbag back roadbed is composed of soilbags (1), a bridge/culvert tunnel (2), a back roadbed foundation ditch (3) and a pavement (4) and is characterized in that the soilbags (1) are stacked up layer by layer in a criss-cross manner in the back roadbed foundation ditch (3) of the bridge/culvert tunnel (2) and are tightly combined with asphalt or concrete paved on the pavement (4). The soilbag back roadbed is simple, practical and economical, and has remarkable social and economic benefits.
Description
Technical field
The utility model relates to a kind of back of the body roadbed, particularly a kind of geotechnique's bag platform back of the body roadbed.
Background technology
Between the roadbed that bridges and culverts, passage etc. crosses the structure of highway and the structure platform back of the body bankets, often produce stepped differential settlement because of the rigidity great disparity, cause that " bumping at bridge-head " phenomenon takes place.Though adopting the roadbed of the geonet reinforcement structure platform back of the body to banket at present produces effect to the differential settlement that reduces between structure and the roadbed, but because structure platform back of the body construction space is narrow, backfill is difficult to grinding compacting, therefore, even adopt the geonet reinforcement, the sedimentation that enough bearing capacities can not be provided and reduce backfill effectively, have only the ground of working as to have enough bearing capacities, banketing under the synergy of heavy load and traffic loading, unlikely destruction and when producing big sedimentation, the geosynthetics reinforcement just can bring about tangible results.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of geotechnique's bag platform back of the body roadbed is provided, and platform back of the body subgrade rating is improved, and sedimentation is even, reduces vibration.
The utility model solves by the following technical programs:
Hold the power situation according to bridges and culverts, channel board back of the body subgrade soil, platform is carried on the back the rubble, the original soil that excavate in the roadbed foundation ditch pack into and form geotechnique's bag behind the geotechnological woven bag tying, it is stand-by to be deposited in the foundation ditch limit; Treat that foundation ditch is by crisscross successively the stacking to the road surface of geotechnique's bag that after the standard arrangement foundation ditch limit is filled; Slit between geotechnique's bag is filled and led up with the place hack; Every layer of geotechnique's bag machinery or hand compaction; The road surface is by standard asphalt or concrete; Geotechnique's bag and bridges and culverts, passage etc. are combined closely,, combine, reach the raising subgrade rating, eliminate differential settlement, reduce the road vibration, dissolve the bumping at bridge-head phenomenon by geotechnique's bag, bridges and culverts passage, platform back of the body roadbed foundation ditch, road surface to strengthen its globality.
The beneficial effects of the utility model are: simple, practicality, saving, economy.
1. simple.Geotechnique's woven bag is directly packed the original soil at bridges and culverts, passage scene into and is formed geotechnique's bag in the bag and be used for platform back of the body roadbed, and crisscross successively stacking to the road surface gets final product after filling and leading up the compacting road surfacing.
2. practical.Geotechnique's bag platform back of the body roadbed not only improves subgrade rating, eliminates differential settlement, and reduces the road vibration; Dissolve the bumping at bridge-head phenomenon.
3. save.The original soil at bridges and culverts, passage scene is directly used, gather materials on the spot, become useless and be usefulness, economize on resources, reduce discharging.
4. economical.Owing to gather materials on the spot, reduce discharging, can significantly save construction fund.
Description of drawings
Accompanying drawing is a sectional structural map of the present utility model.
Among the figure: 1. geotechnique bag, 2. bridges and culverts passage, 3. a back of the body roadbed foundation ditch, 4. road surface.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
In the drawings, rubble, the original soil of excavation in 2 back of the body roadbeds of bridges and culverts passage foundation ditch 3 packed into forms geotechnique's bag 1 behind the geotechnological woven bag tying, and it is stand-by to be deposited in platform back of the body roadbed foundation ditch 3 limits; Treat after platform back of the body roadbed foundation ditch 3 is by the standard arrangement platform carried on the back that geotechnique's bag that roadbed foundation ditch 3 limits fill 1 is crisscross successively stacks to the road surface 4; Slit between geotechnique's bag 1 is filled and led up with the place hack; Every layer of geotechnique's bag machinery or hand compaction; Road surface 4 is by standard asphalt or concrete.Combine by geotechnique's bag 1, bridges and culverts passage 2, platform back of the body roadbed foundation ditch 3, road surface 4, reach the raising subgrade rating, eliminate differential settlement, reduce the road vibration, dissolve the bumping at bridge-head phenomenon.
Claims (1)
1. geotechnique's bag platform back of the body roadbed is characterized in that: combined by geotechnique's bag (1), bridges and culverts passage (2), platform back of the body roadbed foundation ditch (3), road surface (4), form geotechnique's bag platform back of the body roadbed.
