Problems solved by technology

[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. The soil will expand when it meets water. If the soil expands and deforms to a certain extent and the stress cannot be released in time, it will destroy the rigid structure and cause damage to the slope protection structure.

Embodiment 1

[0060] Such as Figure 1-Figure 4As shown, the present embodiment provides a waterproof slope protection, including an expansive soil slope 1, a slope top protection platform 2, a slope foot protection platform 3, a polymer waterproof layer 4, an ecological protection layer 5 and a water guide channel 6. Wherein, the surface layer of the expansive soil slope 1 forms a solidified layer 11 through a soil curing agent, and the slope top protection platform 2 is arranged on the slope top of the expansive soil slope 1, and the slope top protection platform 2 is provided with a slope top water intercepting ditch 21, and the slope The foot protection platform 3 is set at the slope toe of the expansive soil slope 1, the slope toe protection platform 3 is provided with a slope foot drainage ditch 31, the polymer waterproof layer 4 is laid on the surface of the solidified layer 11, and the ecological protection layer 5 is laid on the polymer On the surface of the waterproof layer 4 , th...

Embodiment 2

[0099] Such as Figure 5 with Image 6 As shown, the present embodiment provides a kind of waterproof slope protection, and its difference with embodiment one is:

[0100] The ecological protection layer 5 includes a plurality of ecological bags 54 , planting soil layers 51 and ecological vegetation 52 . Among them, a plurality of ecological bags 54 are stacked from bottom to top along the slope direction of the expansive soil slope 1, and are attached to the outside of the polymer waterproof layer 4. The planting soil layer 51 covers the ecological bags 54, and the ecological vegetation 52 is arranged on the planting soil layer 51. superior.

[0101] The setting of the ecological bag 54 makes the structure of the waterproof slope protection more stable, omitting the support structure of the self-drilling anchor rod 532 and the geogrid 531, and the planting soil layer 51 is mixed with nutrients and green plant seeds, and grows into ecological vegetation after cultivation 52...

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. ...
