Abstract
The invention discloses a geotechnical bag back subgrade and application method. The geotechnical bag back subgrade consists of geotechnical bags (1), a bridge culvert passage (2), a back subgrade foundation pit (3) and a road surface (4), wherein the geotechnical bags (1) are vertically and horizontally laminated layer by layer in a staggering way from the back subgrade foundation pit (3) of the bridge culvert passage (2) and are closely combined with asphalt or concrete which is laid on the road surface (4). The geotechnical bag back subgrade is simple, practical and economical and has obvious social benefit and economic benefit.
Description
Technical field
The present invention relates to the improvement of a kind of back of the body roadbed and method, the improvement of particularly a kind of geotechnique's bag platform back of the body roadbed and method.
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 present invention has overcome deficiency of the prior art, and the improvement of a kind of geotechnique's bag platform back of the body roadbed and method is provided, and platform back of the body subgrade rating is improved, and sedimentation is even, reduces vibration.
The present invention 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,, reach the raising subgrade rating, eliminate differential settlement, reduce the road vibration to strengthen its globality; Dissolve the bumping at bridge-head phenomenon.
The invention has the beneficial effects as follows: 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 invention.
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 present invention 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.
Claims (1)
1. geotechnique's bag platform is carried on the back roadbed and application process, form by geotechnique's bag (1), bridges and culverts passage (2), platform back of the body roadbed foundation ditch (3), road surface (4), it is characterized in that: rubble, the original soil of excavation in bridges and culverts passage (2) the platform back of the body roadbed foundation ditch (3) are 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) limit; 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 (1) that roadbed foundation ditch (3) limit fills 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.
