Problems solved by technology

These two slope protection methods have successfully introduced microbial technology into slope protection engineering; however, when they are applied to reinforce river embankment slopes, they cannot adapt to changes in water level; when the water level changes above the reinforcement section, Bacillus is not suitable If it survives, it loses the effect of strengthening the slope; the fungus is single, and it cannot make full use of the nutrient solution or the effective substances in the embankment fill to proliferate, and the reinforcement effect is limited; and the microbial reinforcement solution is added to the slope by injection or spraying. The uniformity of the microbial reinforcement solution above the aquifer cannot be guaranteed, and the stiffness and strength of the slope body after reinforcement are different, and the stability of the slope is not good
[0005] Regarding the current ecological slope protection technology, generally speaking, the economy is still not strong, and waste cannot be reused. Microbial slope protection can solve these problems well.
However, the strength of a single microbial ecological slope protection is still not enough for the embankment under the strong current of the river.

Embodiment Construction

[0024] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The protection scope of the present invention is not limited only to the description of this embodiment.

[0025] The invention discloses a method for ecological slope protection of river embankments reinforced by microorganisms. It is characterized in that: below the normal water level line, the slope protection form of concrete prefabricated block plus sand and stone cushion is adopted. In the water level change area, the combined slope protection form of dry block stones and aquatic plants is adopted; above the constant water level, the combined slope protection form of microorganisms, plants and geogrids is adopted;

[0026] First, the form of slope protection below the normal water level:

[0027] (1) First lower the water level to the required slope protection depth.

[0028] (2) Lay a coarse sand cushion 1 on the slope surface with a t...

Abstract

The invention discloses a microbial river embankment reinforcement ecological slope protection technology. According to different characteristics of embankment protection above and below a water level line, a microorganism-plant-geogrid combined slope protection form is adopted when the water is above a normal water level line; a dry building block stone-aquatic plant combined slope protection form is adopted at a water level change area; and a concrete prefabricated block, sand and bedding stone slope protection form is adopted when the water is below the normal water level line. According to the technology, the blockage effect and the cementation of microorganisms, the anchoring effect of root systems of the plants on a rock-soil body, strength characteristic in longitudinal and transverse directions of bidirectional geogrids and a locking effect on a soil body are brought into full play, and the integral stability of the river embankment is increased. According to the technology, the microorganism-plant-geogrid combined slope protection form is adopted, so that the technology is economical and environment-friendly, the construction difficulty is also reduced, and the construction time is saved. Meanwhile, according to the condition of the water level line change, different slope protection forms are adopted, so that the impact of a strong water flow can be effectively resisted, and the applicability of the technology to the river embankment slope protection is enhanced.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to an ecological slope protection method for microorganism reinforcement of river banks. Background technique [0002] Traditional river slope protection mainly includes mortar or dry block stone slope protection, cast-in-place concrete slope protection, prefabricated concrete block slope protection, etc. The cost of these slope protection projects is relatively high, and the underwater construction and maintenance work is relatively difficult. Its biggest disadvantage is that it is only designed and constructed from the perspective of satisfying the stability of the river bank slope and the function of flood drainage and drainage of the river, and seldom considers its impact on the environment and ecology. The traditional slope protection project closes the entire river bank surface and isolates the material exchange between the soil and the water...
