Example Embodiment

[0059]Example one

[0060]Such asFigure 1 - Figure 4As shown, this embodiment provides a waterproof slope, including expansion soil slope 1, a slope top guard station 2, a slope shield 3, a polymer waterproof layer 4, an ecosystem 5, and a water guide channel 6. Among them, the surface layer of the expansive soil slope 1 forms a cured layer 11 through the soil curing agent, and the groove top cover 2 is disposed on the groove top of the expansion soil slope 1, and the groove top cover 2 is provided on the grooved groove 21, the slope. The foot shield 3 is disposed on the slope foot of the expansive soil slope 1, and a grooved drainage groove 31 is provided on the slope foot shield 3, and the polymer waterproof layer 4 is laid in the surface of the cured layer 11, and the ecological protective layer 5 is laid in a polymer. The surface of the waterproof layer 4 is provided on the ecosect layer 5, and the water in the groove 21 in the groove 21 can be directed to the slope of the groove 3...

Example Embodiment

[0098]Example 2

[0099]Such asFigure 5 withFigure 6 As shown, this embodiment provides a waterproof slope, which is different from one of the examples in:

[0100]The ecological protective layer 5 includes a plurality of ecological bags 54, planting soil layers 51 and ecological vegetation 52. Wherein, the plurality of ecological bags 54 are stacked from the slope direction of the expansive soil slope 1, which is attached to the outer side of the polymer waterproof layer 4, and the planting layer 51 covers the ecological bag 54, and the ecological vegetation 52 is disposed in planting soil 51. 51 on.

[0101]The setting of the ecological bag 54 causes the structure of the waterproof slope to be more stable, omitted the solid supporting structure of the self-drilling anchor 532, the geogrid 531, and the planting layer 51 is mixed with nutrients and green seeds, and the cultivation is grown into an ecological vegetation. 52. It can effectively reduce soil loss, thereby acting as a waterproof ...

Abstract

The invention belongs to the technical field of slope protection, and discloses a waterproof protection slope. The waterproof protection slope comprises an expansive soil slope, a slope top protection table, a slope toe protection table, a polymer waterproof layer, an ecological protection layer and a water guide channel. A solidification layer is formed on the surface layer of the expansive soil slope through a soil solidification agent; the slope top protection table is arranged on the slope top of the expansive soil slope; a slope top intercepting ditch is formed in the slope top protection table; the slope toe protection table is arranged on the slope toe of the expansive soil slope; a slope toe drainage ditch is formed in the slope toe protection table; the polymer waterproof layer is formed by combining one or more of waterproof coatings or cast-in-place coiled material waterproof layers; the polymer waterproof layer is laid on the surface of the solidification layer; the ecological protection layer is laid on the surface of the polymer waterproof layer; the water guide channel is formed in the ecological protection layer; and water in the slope top intercepting ditch can be guided to the slope toe drainage ditch. According to the waterproof protection slope, the polymer waterproof layer can reliably protect the expansive soil slope, and stress generated by expansive soil slope deformation can be buffered and released.

Description

technical field [0001] The invention relates to the technical field of slope protection, in particular to a waterproof slope protection. Background technique [0002] The expansive soil in the slope protection structure is a special cohesive soil with significant water sensitivity. Its main characteristics are that it expands and softens when exposed to water, shrinks and cracks after losing water, and the deformation process of swelling when wet and shrinking when dry can be repeated. . After the expansive soil has undergone repeated drying and wetting cycles, its strength is significantly reduced, which is likely to cause landslide accidents on expansive soil slopes. Therefore, waterproof measures for expansive soil slopes are very important to the problem of expansive soil slopes. [0003] In view of the above problems, most of the existing treatment methods use rigid structures such as geotechnical retaining walls or anti-slide piles to protect expansive soil slopes. ...
