Abstract

The invention discloses a soil-conservation permeable ecological slope structure. The soil-conservation permeable ecological slope structure is composed of repetitive units which are sequentially spread on a slope. Each repetitive unit is formed by splicing a longitudinal water seepage block and a transverse water seepage block, wherein a longitudinal water seepage pipe which penetrates through the two ends of the longitudinal water seepage block is arranged in the longitudinal water seepage block, and a transverse water seepage pipe which penetrates through the two ends of the transverse water seepage block is arranged in the transverse water seepage block; and the longitudinal water seepage block or the transverse water seepage block is provided with a side edge groove communicating with the interior of the water seepage pipe in the longitudinal water seepage block or the interior of the transverse water seepage block, and the longitudinal water seepage pipe communicates with the transverse water seepage pipe through the side edge groove. In each repetitive unit, a soil layer is laid at the bottom, and a protection layer is laid at the top. The soil-conservation permeable ecological slope structure is high in strength and durable; water and soil on the slope can be conserved and are not prone to loss, meanwhile, the ecological slope structure has good permeability, and thus vegetation and soil on the slope are prevented from getting loose after being soaked by water.

Description

technical field [0001] The invention relates to a soil-preserving and water-permeable ecological slope structure, which belongs to the technical field of revetment engineering. Background technique [0002] The construction of highways, railways, water conservancy and other projects is closely related to the natural environment; the projects are large in scale, with many projects and involve a wide range of areas. A large number of exposed soil and rock slopes formed by earth and rock filling and excavation projects destroy the existing vegetation and have a relatively large impact on the local ecological environment. In the past, simple engineering protection was usually used, such as mortar (dry) masonry, spray anchor protection, etc. These engineering measures have caused a series of ecological environment and engineering problems such as the destruction of original vegetation, soil erosion, landslides, and slope instability. . Ecological slope construction can take engi...
