Chevron shaped hollow backbone comprises the main framing and chevron shaped the skeleton that is connected main framing of vertically laying along side slope, and main framing is laid and formed by U-shaped precast concrete hollow pot, and chevron shaped skeleton laid and formed by L-type precast concrete hollow pot.Main framing spacing is 1.0～3.0 meters, and chevron shaped skeleton spacing is 2.0～3.0 meters.Chevron shaped skeleton spacing refers to the air line distance of neighbouring skeleton corresponding points, as the air line distance between chevron shaped the chevron shaped middle intersection point of skeleton.
Pattern hollow backbone comprises oblique the skeleton along the oblique laying of side slope, and oblique skeleton intersects and form square, and oblique skeleton and top fringing and end fringing form respectively triangle.Oblique skeleton laid and formed by L-type precast concrete hollow pot.The square length of side of oblique skeleton intersection formation is 1.0～3.0 meters.
Between precast concrete hollow pot, adopt cement mortar mud jacking to build by laying bricks or stones, main framing adopts concrete cast-in-situ with non-standard that props up skeleton node.
The precast concrete hollow backbone protective slope structure that the utility model relates to is laid and is formed along side slope by precast concrete hollow pot, and precast concrete hollow pot is placed in the groove excavating in side slope.The U-shaped framework part of U-shaped precast concrete hollow pot and the L-type frame of L-type precast concrete hollow pot are placed in more than side slope ground, make the main framing of laying along side slope and prop up the dash edge that forms high 8cm～10cm on skeleton.
The precast concrete hollow pot that the utility model is laid along side slope has been realized factory normalization production; have advantages of that lightweight, intensity is large, construction is simple, save production cost; combining with green plant protection in skeleton; can play side slope protection effect; can reach good landscape effect again, reach and improve construction environment, improve operating efficiency; make hollow backbone protective slope structure be conducive to ecological protection, avoid soil-slope
Erosion damage, really plays the side slope protection effect of roadbed, dykes and dams, is specially adapted to the soil-slope protection such as railway, highway, water conservancy.
