Problems solved by technology

[0005] The ecological concrete prefabricated blocks are not connected to each other, and can only rely on osmosis to discharge the accumulated water in the ecological concrete prefabricated blocks, so that the plant roots in the ecological concrete prefabricated blocks can be immersed in water for a long time in the rainy season; the soil in the ecological concrete prefabricated blocks is breathable poor performance, which is not conducive to the growth of plants; the planted plants have poor purification ability to the water flowing into the river through slope protection, and there are still a lot of pollutants in the water flowing into the river

Embodiment 1

[0045] as attached figure 1 and 2 Shown, a kind of river channel ecological slope protection provided for an embodiment of the present invention, described river channel ecological slope protection comprises:

[0046] ramp1;

[0047] The slope 1 is laid with a hollow prefabricated part 2; the side of the hollow prefabricated part 2 is provided with a through hole; the through holes connecting the two hollow prefabricated parts 2 are connected;

[0048] The interior of the hollow prefabricated part 2 is filled with a planting base; the planting base at least includes soil, ceramsite, biochar and plant fibers.

[0049] In the embodiment of the present invention, suitable planting plants can be selected in the planting base according to the location of the ecological slope protection of the river channel and the local natural environmental conditions. When the surface runoff on the river bank flows into the water body in the river channel through the ecological slope protectio...

Abstract

The invention is applicable to the technical field of artificial river channels, and provides a river channel ecological protection slope and a construction method thereof. The river channel ecological protection slope comprises a slope, wherein hollow prefabricated parts are laid on the slope; through holes are formed in the side surfaces of the hollow prefabricated parts; the through holes of the two connected hollow prefabricated parts communicate with each other; the hollow prefabricated parts are filled with planting bases; and the planting bases comprise at least soil, ceramsite, biocharand plant fibers. According to the river channel ecological protection slope and the construction method thereof, the through holes are formed in the side surfaces of the hollow prefabricated parts,so that the through holes of the two connected hollow prefabricated parts communicate with each other, and the problem that plants are in a flood disaster due to water accumulation in the hollow prefabricated parts can be effectively solved; the hollow prefabricated parts are filled with the ceramsite, so that the air permeability of the soil can be effectively improved, and the growth level of the plants can be improved; and the planting bases are filled with the biochar and the plant fibers, so that pollutants which are flushed into a river channel by rainwater and surface runoff can be adsorbed, and the purification capacity of a water body can be effectively improved. By utilizing the river channel ecological protection slope and the construction method thereof, a river channel ecological system can be repaired and improved.

Description

technical field [0001] The invention belongs to the technical field of artificial rivers, in particular to a river ecological slope protection and a construction method thereof. Background technique [0002] Ecological slope protection means that after the formation of the excavated slope, the anchorage of the plant root system to the rock and soil is used to protect and reinforce the surface of the slope, so that it can not only meet the requirements for the stability of the slope surface, but also restore the damaged surface. The slope protection method in the natural ecological environment is an effective means of slope protection and slope consolidation, and is usually used on both sides of rivers and roads. [0003] The traditional ecological slope protection structure is to lay ecological concrete prefabricated blocks on the river or bank revetment, and suitable plants can be planted in the ecological concrete prefabricated blocks, so as to realize the purpose of concr...
