A special soil cutting slope ecological protection structure and its construction method

Abstract

The invention discloses a special soil cutting slope ecological protection structure and a construction method thereof. The special soil cutting slope ecological protection structure includes a recoverable yielding anchor rod, a frame beam, an anti-seepage layer, and a guest soil spraying layer , anti-scour layer, slope drainage ditch, slope bottom drainage ditch, slope top drainage ditch and water storage device; the sash beam is set on the slope surface, and one end of the returnable pressure anchor is connected to the sash beam, which can be restored and let The other end of the pressure anchor is buried in the slope, the anti-seepage layer is covered on the slope, the foreign soil spraying layer is set in the frame beam, the anti-scouring layer is set on the foreign soil spraying layer, and the slope drainage ditch is laid On the slope, the slope bottom drainage ditch is arranged at the bottom of the slope, the slope top drainage ditch is arranged at the top of the slope, and the water storage device is arranged in the sash beam. The special soil cutting slope ecological protection structure can reduce the risk of slope instability and collapse caused by rainwater infiltration on the special soil cutting slope, and its anchorage system can coordinate with the slope deformation, and has the function of recovering pressure.

Description

technical field [0001] The invention relates to the field of slope protection engineering, in particular to a special soil cutting slope ecological protection structure and a construction method thereof. Background technique [0002] Special soil refers to soil with special composition, state, and structural characteristics. Common special soils mainly include expansive soil, collapsible loess, red clay, and frozen soil. Expansive soil swells when soaked in water and shrinks when it loses water, and its shear strength will also decrease greatly after multiple cycles of expansion and deformation, while collapsible loess has a large pore ratio and strong intergranular cementation, and its strength is higher when it is not exposed to water , once it is soaked by water, the soil particle structure will be destroyed rapidly, large settlement will occur, and the strength will decrease rapidly. It can be found that the properties of special soils are easily affected by water, and ...

Problems solved by technology

[0003] For special soil slopes, the traditional treatment methods include arched skeleton protection of masonry rubble, slope protection of hollow hexagonal bricks, skeleton protection of concrete frame beams, and slope protection of liquid quick-setting agent, but these protective measures are difficult to improve The ability of slope to prevent rainwater infiltration, and the effect of ecological protection is not enough; , hexagonal bricks, concrete frame, etc. will be displaced and damaged to varying degrees when the slope is deformed, and the ability to restrain the slope deformation is insufficient.
