Ecological slope protecting method

[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, combustion ash and water in the lower layer of fertilizer-containing porous concrete are: 700 parts of coarse aggregate, 150 parts of fine aggregate, 115 parts of binder, 12 parts of combustion ash, and 45 parts of water.

[0036] Ingredients

[0037] c) Spray the lower water purification layer on the surface of the lower fertilizer-containing porous concrete: After the lower surface of the lower fertilizer-containing porous concrete solidifies, the TiO 2 The photocatalyst, artificial zeolite and cement are stirred and mixed, and then sprayed as a powder or dissolved in water to form an emulsion spray. TiO 2 Nano TiO 2 White powder, model VK-TG01 (Hangzhou Wanjing New Material Co., Ltd.), PH value 6-8, average particle size 25nm; chemical composition of artificial zeolite is shown in Table 2 (Ninghai County Jiahe Chemical Co., Ltd.), specific gravity 1.92g/ cm 3 , The particle size distribution is 0.5-1mm. TiO 2 The weight parts of photocatalyst, artificial zeolite and cement are: TiO 2 1 part of photocatalyst, 5 parts of artificial zeolite, 100 parts of cement.

[0040] d) Laying the upper layer of reinforced porous concrete: Stir and mix coarse aggregate, fine aggregate, binder, fly ash and water reducing agent, and finally add water, stir evenly, and lay it on the smooth slope to be treated. Consolidate. The coarse aggregate is crushed stone with a particle size of about 2 cm; the fine aggregate is artificial sand with a particle size of about 0.5 cm; the binder is ordinary Portland cement 525R (Jiangsu Nanjing Changjiang Cement (Group) Company China Cement Plant); powder The coal ash is taken from a power plant in Nanjing; the high-performance water reducing agent is M1 series of high water reducing polycarboxylic acid water reducing agent (Jiangsu Aolaite New Material Co., Ltd.); water is tap water. The weight parts of coarse aggregate, fine aggregate, binder, fly ash, water reducing agent and water in the upper reinforced porous concrete are: 1360 parts of coarse aggregate, 100 parts of fine aggregate, 123 parts of binder, and fly ash 60 parts, 0 parts water reducing agent, 35 parts water.

[0041] e) Spray the upper water purification layer on the surface of the upper strengthened porous concrete: After the upper strengthened porous concrete surface is initially solidified, the TiO 2 The photocatalyst, artificial zeolite and cement are stirred and mixed, and then sprayed as a powder or dissolved in water to form an emulsion spray. TiO 2 Nano TiO 2 White powder, model VK-TG01 (Hangzhou Wanjing New Material Co., Ltd.), PH value 6-8, average particle size 25nm; chemical composition of artificial zeolite is shown in Table 2 (Ninghai County Jiahe Chemical Co., Ltd.), specific gravity 1.92g/ cm 3 , The particle size distribution is 0.5-1mm. TiO 2 The weight parts of photocatalyst, artificial zeolite and cement are: TiO 2 1 part of photocatalyst, 5 parts of artificial zeolite, 100 parts of cement.

[0042] f) Fill the voids of the upper reinforced porous concrete with planting materials: Planting materials should be selected according to the site environment, plant species, and slope management needs. The basic composition is a mixture of soil, grass seeds, agricultural compound fertilizer and water retaining agent. The weight parts of soil, grass seeds, agricultural compound fertilizer and water retaining agent in the plant material are: 12,000 parts of soil, 45 parts of grass seeds, 150 parts of agricultural compound fertilizer, and 20 parts of water retaining agent.

[0043] g) Natural conservation.

[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.

[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.
