Embodiment 1

[0034]Such asfigure 1 A permeable mesh, including water grid 1, water-water mesh 1, a square distribution, water grid 1 section is "L" shape, the mesh is not more than 6.25m2; "L "The upper side of the upper portion of the shady water mesh 103 is the water tank 101. The material of the water-water mesh 1 is abandoned concrete; the matching ratio of the sandless concrete is cement: gravel: water = 1: 5: 0.4; cement is ordinary silicate cement, gravel, gravel, grade of 42.5 The particle diameter is 16 to 31.5 mm.

[0035]Among them, a layer of cement sand pulp is provided with a layer of cement sander water guideline 102; the water slurgium 101 can limit the water distribution area, introducing a water-water grid in a square mesh 1 , Reduce hydraulic flush strength.

[0036]Among them, the "L"-shaped lateral pendant mesh 103 is also laid with a nonwoven geotechnic fabric 2, and the non-woven soil is 2 quality is 10 ~ 15g / m.2. Non-woven geotechnical cloth 2 plays a refiltration effect.

Abstract

The invention relates to the technical field of slope protection engineering, and particularly relates to a water-permeable grid ecological protection slope and a construction method thereof. The water-permeable grid ecological protection slope comprises water-permeable grids, wherein the water-permeable grids are arranged on a slope surface in a square or herringbone shape; and the water-permeable grids are made of non-fine concrete. When the water-permeable grids are arranged in the square shape, the cross sections of the water-permeable grids are L-shaped, and the protruding parts of one sides of the upper parts of the water-permeable grids with the L-shaped cross sections are water guide ridges. When the water-permeable grids are arranged in the herringbone shape, the cross sections ofthe water-permeable grids comprise L shapes and U shapes; and the protruding parts of one sides of the upper parts of the water-permeable grids with the L-shaped cross sections are water guide ridges, and the protruding parts of the two sides of the upper parts of the water-permeable grids with the U-shaped cross sections are water guide ridges. According to the ecological protection slope, the hydraulic action intensity can be reduced, and the slope surface is prevented from being scoured in a centralized mode; the slope surface drainage speed can be increased, and the slope runoff is prevented from corroding the slope; and the underground water level can be reduced, and the anti-skid stability and safety of the slope are improved.

Description

Technical field[0001]The present invention relates to the field of prototopenel engineering, and in particular to a water grid ecological slope and its construction method.Background technique[0002]At present, the roadbed, roads soil slope, water conservancy projects, and slopes such as the slope of the soil water slope, more of the concrete skeleton leather slope technology, which is designed to prevent slopes from being affected by hydraulic erosion in the slope. Restore ecological vegetation.[0003]Concrete skeleton craft slope technology, is a concrete skeleton arranged on the surface of the earthen slope, and a green slope technology in the mesenteric plants. The working principle is to use the interception, water-saving function of the skeleton, and reduce slope hydraulic flushing; and reach the hydrological effect of the ground biomass by mesenter-building mechanics and the hydrological effects of the upper biomass, reaching the slope protection and ecological environment impr...
