Embodiment
It it is that one provided by the invention can inherently improve edge slope structure performance as shown in Figure 1 and Figure 2, it is to increase the antiseepage surface layer structure of slope stability. Described antiseepage surface layer structure comprises protective layer 1, and described protective layer 1 is low absorption water modification compacting soil layer. Above by the former soil of common side slope extremely strong for existing water-absorbent is modified to low water absorbable Modified soil and tamp into low absorption water modification compacting soil layer, then covered the geology edge slope structure formed on existing soil-slope described in the application. Like this, owing to described protective layer 1 is that low absorption water modification compacting soil layer is formed, such that it is able to protective layer 1 described in ensureing meet after water can not because of self stronger water-absorbent a large amount of absorption moisture, and then ensure that the strength and stability of described protective layer, add that the protective layer after compacting 1 hardness is relatively big, quality is extremely close, thus it is inner to prevent rainwater from infiltrating slope body by described protective layer greatly, reaches the object improving slope stability. By above-mentioned technical scheme it will be seen that the technique scheme that the application adopts is by from forming in the performance of the former soil of described protective layer the improvement carried out, such that it is able to realize the object inherently improving edge slope structure performance.
In above-mentioned enforcement mode, gather materials on the spot in conjunction with existing engineering building materials, with get with, and convenient and reliable reality, the described low absorption water modification compacting soil layer that the application adopts is tamped with the equal batch mixing of white lime by the former soil of side slope, and described in described equal batch mixing, the former soil of side slope and described white lime are prepared burden in the ratio of 3:7,2:8 or 4:6. Like this, not only cost is low for white lime material, and produces conveniently, the more important thing is that white lime has water-absorbent strong, after water suction, self performance can obtain the advantage effectively improved, thus makes the not only laid down cost of the protective layer described in the application, and performance can be improved and ensure. Moreover, in order to ensure the compacting effect of described protective layer, all control to be no more than in the scope of 5 by the particle diameter of the former soil of side slope and white lime that form described equal batch mixing.
Further, also comprise the constructional feature of artificial earth fill's layer 5 in conjunction with existing edge slope structure, described protective layer 1 is attached to the outside of described artificial earth fill's layer 5; And the discharge slope body in order to facilitate the energy of the infiltration in the body of slope instant, in described antiseepage surface layer structure, also it is provided with rubble permeable layer 6, and described rubble permeable layer 6 is arranged into the inner side of described artificial earth fill's layer 5. Like this, infiltrate the infiltration in the body of described slope and just can discharge slope body very easily. Simultaneously, in order to make the infiltration of discharge slope body not damage artificial earth fill's layer 5 and the protective layer 1 of side slope, antiseepage surface layer structure described in the application also comprises infiltration system 8, the output terminal of described infiltration system 8 stretches out described protective layer 1, and the input terminus of described infiltration system 8 is connected with described artificial earth fill's layer 5. The plastics tubing 9 of now preferably described infiltration system 8 for being interspersed in described protective layer.
Again in conjunction with the difference of antiseepage surface layer structure and common concrete structure, in order to ensure that protective layer 1 and artificial earth fill's layer 5 can not occur the phenomenon of delamination before because of gravity or infiltration, antiseepage surface layer structure described in the application also comprises transition muscle 7, and described protective layer 1 is connected as a whole with the shear surface of described artificial earth fill 5 side slope by described transition muscle 7. Like this, even if also being not easy to occur between protective layer 1 and described artificial earth fill 5 to produce the serious natural disasteies such as landslide because of delamination owing to seeping water.
Embodiment one
As shown in Figure 1, 2, in artificial backfill side slope, slope shoulders, for the slope shoulder having pedestrian to walk, it is possible to adopt certain thickness concrete to lay; For the slope shoulder walked without pedestrian, it is possible to directly adopt the processing layer such as certain thickness dirt or lime.
Treatment on slope layer adopts the processing layer such as dirt or lime. At treatment on slope layer at a certain distance, plastics water seepage hole and plastics tubing 9 is buried in advance.
In order to make treatment on slope layer consistent with slope body deformability, the mode adopting reinforcing body namely to add transition muscle 7 processes, and makes the soil body and makes treatment on slope layer mortise.
For the ease of construction, treatment on slope layer and protective layer 1 have certain rigidity, simultaneously for making reinforcing body namely play a role by transition muscle 7, it is necessary to making reinforcing body at the embedding certain length for the treatment of on slope layer, treatment on slope layer reaches certain thickness could meet requirement.
The above-mentioned of the present invention's employing lays one layer of certain thickness lime treatment layer on soil-slope surface, prevents rainwater from domatic infiltration slope body, is applicable to manually backfill soil-slope and nature soil-slope. In artificial backfill soil-slope, it is also possible to build rubble filter water-band slope body inside paving, discharge the unnecessary water in the body of slope in time. In domatic lime treatment layer and slope body, rubble filter water-band, forms effective water-impervious and discharge structure system.
