Abstract
The utility model relates to subgrade construction, is specially a kind of soft rock filling roadbed, and solving existing soft rockmass roadbed filling, to there is cost high and cause the problem of environmental disruption.Soft rock is filling roadbed, comprise soft rockmass filling body, the inclined plane of soft rockmass filling body is provided with inclination bound edge soil layer, the upper surface of soft rockmass filling body is provided with horizontal bound edge soil layer, horizontal bound edge soil layer upper surface is provided with road surface, inclination bound edge soil layer upper surface is provided with the geogrids layer be anchored in soft rockmass filling body, is banded with plastic tape, and is provided with horizontal banket bottom geogrids layer between adjacent geogrids layer.The utility model reasonable in design is reliable, acted on by " water shutoff is held one's breath " of bound edge soil, achieve the feasibility that soft rockmass is filling roadbed, and achieve effective utilization of soft rockmass, reduce construction costs, laugh at appropriation of land and the destruction to natural environment simultaneously, there is simple, the easy to operate and advantage that cost is low of structure.
Description
Technical field
The utility model relates to subgrade construction, is specially a kind of soft rock filling roadbed.
Background technology
China is vast in territory, and the distribution of global biosphere soft rockmass is very extensive, and expressway construction runs into the filling roadbed problem of soft rockmass (comprising strong-weathered rock) unavoidably.Soft rockmass does not allow direct filling roadbed, in the area of earthwork abundance, generally all as the process of discarded side, increases borrow earth side again simultaneously, meet the filler demand of roadbed.Say from construction costs, cause great waste, and larger destruction is caused to environment.
But some area can not find qualified roadbed filling substantially except soft rockmass, in this case, have to select soft rockmass filling roadbed, general employing high-power machinery strong rammer, because soft sillar is higher relative to rock mass compressive strength, and rock mass is aerial construction, and pressing power requires larger, degree of compaction not easily ensures, and cost of compaction will sharply increase.
Summary of the invention
To there is cost high and cause the problem of environmental disruption in order to solve existing soft rockmass roadbed filling for the utility model, provides a kind of soft rock filling roadbed.
The utility model adopts following technical scheme to realize: soft rock is filling roadbed, comprise soft rockmass filling body, the inclined plane of soft rockmass filling body is provided with inclination bound edge soil layer, the upper surface of soft rockmass filling body is provided with horizontal bound edge soil layer, horizontal bound edge soil layer upper surface is provided with road surface, inclination bound edge soil layer upper surface is provided with the geogrids layer be anchored in soft rockmass filling body, is banded with plastic tape, and is provided with horizontal banket bottom geogrids layer between adjacent geogrids layer.
By arranging inclination bound edge soil layer and horizontal bound edge soil layer, avoid soft rockmass filling body and external air flow, surface water, groundwater contacts, reach good sealing effect, and by arranging geogrids layer, reduce to banket and rockfill the differential settlement of part, and overcoming existing soft rockmass roadbed filling, to there is cost high and cause the problem of environmental disruption.
The utility model reasonable in design is reliable, acted on by " water shutoff is held one's breath " of bound edge soil, achieve the feasibility that soft rockmass is filling roadbed, and achieve effective utilization of soft rockmass, reduce construction costs, decrease appropriation of land and the destruction to natural environment simultaneously, there is simple, the easy to operate and advantage that cost is low of structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-soft rockmass filling body, 2-inclination bound edge soil layer, the horizontal bound edge soil layer of 3-, 4-road surface, 5-geogrids layer, the horizontal banket of 6-.
Detailed description of the invention
Soft rock is filling roadbed, comprise soft rockmass filling body 1, the inclined plane of soft rockmass filling body 1 is provided with inclination bound edge soil layer 2, the upper surface of soft rockmass filling body 1 is provided with horizontal bound edge soil layer 3, horizontal bound edge soil layer 3 upper surface is provided with road surface 4, inclination bound edge soil layer 2 upper surface is provided with the geogrids layer 5 be anchored in soft rockmass filling body 1, is banded with plastic tape between adjacent geogrids layer 5, and is provided with horizontal banket 6 bottom geogrids layer 5.
In specific implementation process, the tensile strength of geogrids layer 5 requires to be not less than 160KN/m, and the colligation spacing of geogrids layer 5 is 1.0m; The anchoring depth of geogrids layer 5 is not less than 1m, and holdfast adopts No. 10 reinforcing bars to bend and forms, and holdfast length is not less than 30cm, and holdfast spacing is 2.0m.
