Example Embodiment

[0031] Example 1:

[0032] Such as figure 1 As shown, an ecological slope protection method of the present invention includes the following steps:

[0033] a) Smooth the slope to be processed.

[0034] b) Paving the lower layer of fertilizer-containing porous concrete: mix the aggregate, binder, combustion ash and water, and lay it flat on the smooth slope to be treated, and slab compaction. Aggregates include coarse aggregates (aggregates with a particle size of 1-3cm) and fine aggregates (aggregates with a particle size of 0.1-1cm). Coarse aggregates are dried gravel sludge with a particle size of about 2cm, and fine aggregates It is crushed stone sludge with a particle size of about 0.5cm; the binder is ordinary Portland cement 525R (China Cement Plant of Nanjing Changjiang Cement (Group) Company, Jiangsu Province); the combustion ash is bark combustion ash, and the chemical composition is shown in the table 1; Water is tap water. The weight parts of aggregate, binder, combust...

[0044] Example 2:

[0045] An ecological slope protection method of the present invention adopts the same steps and methods as in Example 1, and resets the weight parts of aggregate, binder, combustion ash and water in the lower layer of fertilizer-containing porous concrete in step b) of Example 1. For example, it is specifically: 500 parts of coarse aggregate, 350 parts of fine aggregate, 115 parts of binder, 12 parts of combustion ash, and 45 parts of water.

Example Embodiment

[0046] Example 3:

[0047] An ecological slope protection method of the present invention adopts the same steps as in Example 1, and resets the weight parts of aggregate, binder, combustion ash and water in step b) of the lower layer of fertilizer-containing porous concrete in Example 1. : 700 parts of coarse aggregate, 150 parts of fine aggregate, 115 parts of binder, 20 parts of combustion ash, 45 parts of water; reset the step c) TiO in the lower water purification layer of Example 1 2 The weight of photocatalyst, artificial zeolite and cement, specifically: TiO 2 1 part of photocatalyst, 5 parts of artificial zeolite, and 100 parts of cement are used as this example.

Abstract

The invention provides an ecological slope protecting method. The method includes the steps of a, leveling a to-be-process slope; b, laying lower-layer fertilizer-containing porous concrete; c, spraying a lower-layer water quality purifying layer on the surface of the lower-layer fertilizer-containing porous concrete; d, laying upper-layer reinforcing porous concrete; e, spraying an upper-layer water quality purifying layer on the surface of the upper-layer reinforcing porous concrete; f, filling plant-growing materials in the gaps of the upper-layer reinforcing porous concrete; g, naturally curing. The ecological slope protecting method has the advantages that double-layer structure synergy is used, the sustainable fertilizer efficiency of the ecological concrete can be increased, the water quality purifying capability of the ecological concrete can be enhanced, and slope stability and water flow impact resistance can be increased fast.

Description

technical field [0001] The invention relates to an environmental treatment method, in particular to an ecological slope protection method. Background technique [0002] Traditional slope protection works are effective in stabilizing slopes, but they ignore the needs of environmental protection and biological survival. With the enhancement of people's awareness of environmental protection and the requirement of protecting the ecological environment, a single engineering slope protection can no longer meet the needs of the development of human society. Considering how to restore the ecology while protecting the slope has been concerned by more and more experts and scholars. Therefore, the emergence of ecological slope protection complies with the requirement of coexistence between man and nature. It is not only a great progress in slope protection engineering construction, but also will become the mainstream of slope protection engineering construction in the future. [0003]...
