Embodiment 1
[0063] Embodiment 1: The use of ecological concrete in the road shoulder of expressway
[0064] Such as Figure 5 As shown, the use of ecological concrete in the road shoulder of the expressway specifically includes:
[0065] 1) Lay permeable concrete on the road shoulder of the expressway and plant soil vegetation to form a 75cm planted concrete;
[0066] 2) Lay stepped PE anti-seepage cloth, unscreened gravel drainage layer, and permeable geotextile in sequence under the expressway shoulder. The PE anti-seepage cloth 3 is covered with an unscreened gravel drainage layer 1, and the unscreened gravel drainage layer 1 is covered with a permeable geotextile 2, and the surface of the permeable geotextile is covered with a permeable concrete 5, and the permeable concrete 5 is covered Planted soil vegetation 6.
[0067] Each step of the stepped PE anti-seepage cloth has a width of 15cm and a height of 18cm; the unscreened gravel drainage layer is divided into two parts: inclined...
Embodiment 2
[0071] Example 2: The use of ecological concrete in the drainage ditch of the expressway
[0072] The cross-section of the ecological side ditch is trapezoidal or triangular, and the bottom of the ditch is made of permeable concrete and grass seeds are sown.
[0073] Such as Figure 6 As shown in (a), the section of the ecological gutter adopts a trapezoidal form, the width of the trapezoidal bottom is 80cm, and the width of both sides is 50cm; the thickness of the planting concrete at the bottom is 20cm, and the internal width of the ecological gutter is 40-60cm.
[0074] Such as Figure 6 As shown in (b), the section of the ecological side ditch is in the form of a triangle, and the width of the triangle bottom is 40cm, 100cm, 40cm; the thickness of the planting concrete at the bottom is 20cm, and the internal width of the ecological side ditch is 40-60cm.
[0075] The open ditch with turf planted in the present invention can prevent water erosion and biological filtration...
Embodiment 3
[0077] Example 3: The use of ecological concrete in constructed wetlands
[0078] The bottom of the artificial wetland is paved with permeable concrete.
[0079] Through the analysis of the sewage purification mechanism of constructed wetlands, it can be known that the most important thing is the good growth of aquatic plants. Constructed wetlands purify sewage mainly through artificial substrates, aquatic plants and microorganisms. The traditional sedimentation tank does not have a good carrier for the survival of aquatic plants and microorganisms. The bottom of the constructed wetland is paved with permeable concrete, and its ecological membrane can act as an artificial substrate to provide a stable attachment surface for the growth of microorganisms. Permeable concrete has large pores, can store water and sediment, and can provide carriers and nutrients for aquatic plants, so that aquatic plants and microorganisms can absorb and utilize nutrients in sewage, absorb and atta...
