The slope covering materials prepared in the embodiments 1 to 11 are uniformly sprayed on a target slope by using a hydraulic spraying device, and after the slope covering materials are naturally dried, slope covering materials can be formed on the slope, so that the technical purpose that plants on the slope have a good growing environment can be achieved by preventing the slope from being washed by rainwater and ensuring certain air permeability, and the thickness of the slope covering materials covering the slope is about 2 cm.
Test example 1 rain erosion detection
In order to verify the anti-scouring effect of the covering material prepared by the application when the covering material is used as a side slope covering, the application simulates the treatment of side slopes with angles of 10 degrees, 20 degrees, 30 degrees and 40 degrees and the rainfall intensities of 80mm/h, 100mm/h, 120mm/h, 140mm/h and 160mm/h respectively, the treatment is carried out for 20 times, each treatment is repeated for 3 times, and the detection result shows that the side slope does not change no matter what test condition, so that the covering material prepared by the application has better anti-rainwater scouring capability.
Test example 2 air permeability test
Because the current side slope covering material has no unified detection standard, and the purpose of using the side slope covering material is to prevent rainwater from washing the side slope and enable the side slope crops to grow normally, the air permeability of the side slope covering material is detected mainly by characterizing the growth state of plants, the air permeability is better when the plants can grow normally to more than 90%, the air permeability is better when the plants can grow normally to more than 70-90%, the air permeability is common when the plants can grow normally to more than 50-70%, the air permeability is poor when the plants can grow normally to less than 50%, the standard of the normal growth of the plants is based on the target covering area, and the plant cultivation and management method is the same as the target covering area.
The method comprises the steps of sowing ryegrass seeds and bluegrass seeds which are sowed in a mixed mode on a slope at a certain position in a test park, dividing the slope into a control area and a treatment area, and spraying slope covering materials prepared in examples 1-10 on each treatment area, wherein the treatment areas of the control area and the treatment area are the same. The observation recorded the coverage of the mixedly sown grass in each treatment of the control zone and the treatment zone from the time of sowing to the time of grass maturity. The observation result shows that the coverage rate of each treated mixed sowing grass can reach the same level as that of the contrast area, and the emergence rate of the treatment area is greater than that of the contrast area in the emergence period of the mixed sowing grass.
Test example 3 flame retardancy test
