Be formed with groove between two adjacent described fins, the cross section of described groove and described fin is trapezoidal.
The cross section of described plant fiber layer is waveform.
The top of described body is provided with through hole, and described through hole is located on the described fin.
The side of described porous concrete structure layer is provided with projection.
The side of described porous concrete structure layer is provided with handle.
Described handle is made of a reinforcing bar that is embedded in the described porous concrete structure layer.
Described fin height is 2:3 with the ratio of described porous concrete structure layer thickness.
Described porous concrete structure layer is 1:15 with the ratio of the thickness of described plant fiber layer.
Described plant fiber layer is coconut fiber layer.
The eco-concrete Revetment block that provides according to the utility model compared with prior art has following advantage: 1, the utility model is combined by porous concrete structure layer and plant fiber layer, the water retention of string and the water permeability of porous concrete interact, and can promote plant to recover sooner growth; 2, form fin by the top at the porous concrete structure layer, can strengthen the soil erosion resistance, erosion resistibility is strong, can effectively prevent the landing of overburden soil, is conducive to plant growth; 3, offer through hole in bodies top, so that keep in touch in earthing and natural ground, keep the water balance of earthing, be conducive to vegetation recovery; 4, in porous concrete structure layer side projection is set, when concrete the use, so that form the gap between every layer of the utility model, has again improved the water balance between earthing and natural ground.

The specific embodiment
Referring to Fig. 1 to Fig. 4, the embodiment of the eco-concrete Revetment block that provides according to the utility model, comprise body, described body is made of porous concrete structure layer 1 and the plant fiber layer 2 that covers on the described porous concrete structure layer 1, and the top of described porous concrete structure layer 1 is formed with fin 11.The utility model adopts porous concrete structure layer 1 and plant fiber layer 2 to combine, and the water retention of string and the water permeability of porous concrete interact, and can promote plant to recover sooner growth; Plant fiber layer 2 in the present embodiment covers the top of described porous concrete structure layer 1 uniformly, the fin of the body surface that makes is more obvious, can strengthen the soil erosion resistance when specifically using, and erosion resistibility is strong, can effectively prevent the landing of overburden soil, be conducive to plant growth.
Referring to Fig. 1 to Fig. 5, according to above-described embodiment of the present utility model, be formed with groove 14 between two adjacent described fins 11, described groove 14 is trapezoidal with the cross section of described fin 11.This kind structure so that the surface of body when earthing, earthing more easily fills up groove 14, helps plant growth and is attached to body surface.
Referring to Fig. 1 and Fig. 3, according to above-described embodiment of the present utility model, the cross section of described plant fiber layer 2 is waveform.Plant fiber layer 2 is to cover uniformly on the porous concrete structure layer 1 in the present embodiment, because the top of porous concrete structure layer 1 is formed with fin 11, so that the cross section of plant fiber layer 2 is waveform.
Referring to Fig. 1 to Fig. 3, according to above-described embodiment of the present utility model, the top of described body is provided with through hole 3, and described through hole 3 is located on the described fin 11.The utility model is by offering through hole 3 in bodies top, through hole 3 penetrates plant fiber layer 2 and porous concrete structure layer 1, so that keep in touch in earthing and natural ground, keeps the water balance of earthing, is conducive to vegetation recovery; Through hole 3 is arranged on the fin 11 so that the groove 14 of body upper surface is interior and can stores more moisture, improve the water retention of body, be conducive to plant growth.
