Abstract
Railroad embankment river valley sand storm protection structure to effectively reduce the influence of sand blown by the wind to railway construction. Set up the fire guard respectively in railroad embankment both sides, the outside of fire guard sets up the plant protective belt, sets up in the plant protective belt outside of the side of facining the wind and hinders husky fence protective belt. Utilizing that the river valley sand blown by the wind is seasonal, the characteristics of the property of water -bearing, accomplishing that the engineering protection of sand blown by the wind and plant protection combine together, compromise the operation safety of railway simultaneously, this protective structure has characteristics such as construction convenience, protecting effect are good, economic, has wide popularization application prospect.
Description
Technical field
This utility model relates to Geotechnical Engineering, particularly to a kind of railroad embankment river valley sand storm protection structure.
Background technology
Part river valley dust storm disease problem is there is in line Canyon Area, Sichuan-Tibet, when railway passes through, owing to railway engineering is typically provided with ballast aggregate, railroad ballast can be polluted after dust storm corrodes and be difficult to clear up, river valley dust storm is usually and to carry out migrating in the case of large wind simultaneously, and railway operation is also had a certain impact by strong wind, when railway engineering with embankment form by time river valley dust storm need to be protected, a kind of river valley sand storm protection structure is needed to solve problems to this end, urgent.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of railroad embankment river valley sand storm protection structure, effectively to reduce the dust storm impact on railway engineering.
This utility model solves its technical problem and be the technical scheme is that
Railroad embankment river valley of the present utility model sand storm protection structure, including railroad embankment, it is characterized in that: described railroad embankment both sides are respectively provided with fire guard, and the outside of fire guard arranges plant protection band, the husky fence buffer zone of resistance is set outside the plant protection band of windward side.
The beneficial effects of the utility model are, utilize river valley dust storm seasonality, the feature of the property of water-bearing, accomplish that the engineering protection of dust storm combines with plant protection, taken into account the operation security of railway simultaneously, this safeguard structure has that easy construction, protection effect be good, economic dispatch feature, has wide popularizing application prospect.
Accompanying drawing explanation
This specification includes such as next width accompanying drawing:
Fig. 1 is the schematic cross-sectional view of this utility model railroad embankment river valley sand storm protection structure.
Component name shown in figure and corresponding labelling: railroad embankment 1, fire guard 2, plant protection band 3, the husky fence buffer zone 4 of resistance.
Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
With reference to Fig. 1, railroad embankment river valley of the present utility model sand storm protection structure, including railroad embankment 1, is respectively provided with fire guard 2 in railroad embankment 1 both sides, the outside of fire guard 2 arranges plant protection band 3, arranges the husky fence buffer zone 4 of resistance outside the plant protection band 3 of windward side.Using fire guard 2 as the slider of railway Yu plant protection band, it is ensured that plant protection band breaking out of fire does not affect railway operation safety.River valley wind sandy land, owing to there is seasonal valley water, can plant applicable growing plants, utilizes plant protection band 3 to fix the sand to prevent dust storm from kicking up and the dust storm kicked up of blocking, and can reduce the wind speed impact on railway engineering simultaneously.The husky fence buffer zone 4 of resistance is utilized to prevent the peripheral dust storm affecting railway from kicking up.
This utility model utilizes river valley dust storm seasonality, the feature of the property of water-bearing, accomplish that the engineering protection of dust storm combines with plant protection, having taken into account the operation security of railway, this safeguard structure has that easy construction, protection effect be good, economic dispatch feature, has wide popularizing application prospect simultaneously.
Described fire guard 2 can use ground to lay ovum rubble, the general 0.3m of thickness, and it arranges width not less than 20m.Described plant protection band 3 can use and plant willow, spacing 1～2m, arranges width and is typically no less than described in 100m the husky fence buffer zone 4 of resistance and uses the husky fence of high vertical resistance, can arrange multiple tracks according to dust storm degree of kicking up, the general 20m of per pass spacing, fence general about 1.5m above ground level.
Some principles of the above this utility model railroad embankment river valley sand storm protection structure that simply explains through diagrams, it is not intended to be confined to by this utility model in shown and described concrete structure and the scope of application, therefore every corresponding amendment being likely utilized and equivalent, belong to the apllied the scope of the claims of this utility model.
