Inclination restoration method of upright channel slope protection

Abstract

The invention discloses an inclination restoration method of upright channel slope protection. A plurality of ecological earthen bowls for planting emerged plants are fixed in a river from the bank sides to the midline position of a channel. The ecological earthen bowls are arranged stepwise so as to form an inclination ecological slope protection, mutually hooked, supported and fixed to the river bottom by ecological stakes or embedded into the upright slope protection by anchor rods, with high stability. Various emerged plants are planted in the ecological earthen bowls, thereby forming an ecological system and ecological landscape that similar natural slope embankments have. The ecological earthen bowls are arranged in the position where rainwater pipes are arranged, and play a role in interception and purification of contaminants in rainwater indirectly. According to the inclination restoration method disclosed by the invention, the shortcomings of land shortage of an upright channel, narrow space, single sectional form, brick-concrete masonry materials and so forth are overcome, and three functions of ecological restoration, sewage interception and water purification as well as landscaping are provided; and the relationship between human beings and the channel is improved fully, and new ideas and technologies are provided for supporting remediation of the upright channel slope protection.

Description

technical field [0001] The invention relates to a river course restoration bowl, in particular to a slope restoration method for vertical river course slope protection. Background technique [0002] In the plain area of ​​my country, there is a large population, dense river networks, and a shortage of construction land. At the same time, based on the consideration of flood control and drainage, it is necessary to carry out engineering renovation of urban rivers, so there are a large number of vertical masonry slope protection rivers. These rivers are generally excavated deep, and the ecosystem is greatly threatened by human activities, basically losing its self-purification ability, and the water quality deteriorates seriously and even becomes black and smelly. In addition, the following characteristics exist in space, shape, material, ecology, relationship with urban facilities, and relationship with human beings: [0003] (1) The space is narrow, houses, factories, roads,...

AI Technical Summary

Problems solved by technology

[0003] (1) The space is narrow, houses, factories, roads, etc. are built along the river, and the side walls of many buildings are river banks. The river ecology is severely encroached and cannot be expanded, and a rich biological community cannot be formed.

[0004] (2) The river channel lacks bends, the shape of the slope protection section is upright and single, and the habitat conditions are scarce, making it difficult to provide the required habitat for organisms

[0005] (3) Slope protection materials are mostly artificial materials such as masonry and concrete, with poor hydrophilicity

[0006] (4) The biological community is single and lacks diversity

[0007] (5) The distance between the river course and urban facilities is short and there is no buffer zone, and the gentle slope and vegetation are easily covered by garbage and sundries

[0008] (6) The distance between the river course and human beings is far, and the river course is too deep, which can neither provide ecological services nor be out of the sight of the surrounding people. It is difficult to arouse the awareness of river course protection, and eventually become a "drainage channel" instead of a normal river course

However, in actual operation, if the original masonry slope protection is demolished, the river channel is widened, and the river channel section is changed, not only is it limited by land use, but also the project is huge, expensive, and will generate a lot of construction waste such as bricks and stones.
