Problems solved by technology

The method of the present invention is based on natural raw materials and the cost is relatively low. It will not affect the growth and development of plants while preventing the backfill soil erosion of bank revetment works. It provides grass planting concrete suitable for plant growth and development, and provides a "plant-microbe" coupling ecology Revetment system to solve the problem that the original ecological revetment technology is not resistant to flood erosion, and the grass body is difficult to survive under the water for a long time

Embodiment 1

[0031] Example 1 Planting test of grass-planting concrete

[0032] 1. According to the strength of grass-planting concrete slope protection and the porosity required for plant growth in the small and medium-sized river control project, the formula of grass-planting concrete used in the planting test is shown in Table 1; the measured performance indicators of the plant concrete test block are shown in Table 2.

[0036]

[0037] 2. Planting concrete planting test equipment

[0038] There are three kinds of utensils used in the plant growth test, one is a cubic glass fiber reinforced plastic utensil with the size of 25×25×25cm, and the other is a rectangular transparent plastic utensil with a size of 40×30×20cm. The transparent utensils are selected because they are convenient for observing plants. The growth and distribution ...

Embodiment 2

[0061] Example 2 Screening of composite microbial inoculants

[0062] 1. Culture of strains

[0063] Bacillus subtilis: Can produce a variety of antibiotics and enzymes, with broad-spectrum anti-strain activity, so it can adapt to the environment by forming high concentrations of resistant endospores.

[0064] Actinomycetes: The most prominent function is to produce a large number of antibiotics, regulate the microflora, have a strong ability to degrade organic matter, and can degrade refractory substances, cellulose and lignin, thereby degrading humus and accelerating nutrient transformation. It is beneficial for plants to better absorb and utilize these nutrients.

[0065] Yeast: It has a large amount of protein and abundant nutrients, which can be used by microorganisms. It is an important nutritional functional bacteria; it can rationally transform and efficiently absorb effective nutrients in various substrate environments including soil. The fermentation and decomposit...

Embodiment 3

[0089] A construction method for "plant-microbe" coupled landscape ecological revetment suitable for inland rivers in northern cities, the method is as follows:

[0090] (1) Site preparation: excavate, level and compact the bank slope, remove sundries in the soil during leveling and compaction; lay a rectangular concrete frame for filling grass-planting concrete on the embankment soil foundation, and remove the buildings in the frame Garbage and sundries, sprinkle water to wet the soil foundation; build brick retaining walls at the foot of the slope and reinforce it with tarpaulin; pour the concrete edge at the top and shoulder of the slope.

[0091](2) Pouring grass-planting concrete: use a concrete mixer to mix grass-planting concrete on site, and pour grass-planting concrete into a rectangular concrete frame. The pouring and filling thickness of the grass-planting concrete is controlled at about 7cm. After the grass-planting concrete is poured and filled, it is immediately ...

Abstract

The invention relates to a "plant-microorganism" coupled type landscape ecological revetment construction method suitable for an inland river of a northern city. Grass seeds: sedum sarmentosum bunge and festuca arundinacea suitable for growing in the north are selected as revetment plants, composite flora suitable for plant growth are selected and designed, and with plant grass concrete as a growing substrate, a "plant-microorganism" coupled type ecological revetment is formed. According to the"plant-microorganism" coupled type landscape ecological revetment construction method suitable for the inland river of the northern city, influences of terrain, weather, hydrology and other factors on plant growth are comprehensively considered, construction is easy, cost is low, the slope excavationand backfill earthwork amount can be greatly reduced, the land occupied by engineering is saved by 30% or above, and investment of part of the engineering can be saved by 61%. Besides, application ofdimension stones, cement, steel bars and other materials is reduced, pollution and damage of human activities to the natural environment are reduced, the energy consumption is reduced to the maximumextent, the emission amount of carbon dioxide is reduced, oxygen is added for the natural environment, the water quality of the waterfront environment can be improved easily, and the environment benefits are obvious.

Description

technical field [0001] The invention relates to a "plant-microorganism" coupled landscape ecological bank protection system suitable for inland rivers in northern cities, and belongs to the technical field of river bank restoration and regulation. Background technique [0002] With the rapid development of science, technology and economy, human life, production and other activities have destroyed the original ecological cycle, and caused many water problems such as lack of water resources, flood disasters, water pollution, and degradation of rivers and lakes. Most of the traditional water conservancy engineering drainage modes are simple and rude quick-draining methods. They only consider how to make the floods drain faster and more smoothly. Stone and other cement river bank protections weaken the ability of rivers to store and seep water, and block the water cycle between rivers and ecological land; moreover, in appearance, this kind of dense hard material slope protection...
