Problems solved by technology

In terms of operation and maintenance, the establishment of wooden piles in the river will hinder the implementation of dredging projects in the water body in the future, and it is also not conducive to the protection of state-owned assets
In terms of resource utilization, the use of a large number of wooden piles will cause excessive utilization of forest resources, which is not conducive to environmental protection

Embodiment 1

[0045] Simple shallow root type

[0046] Such as figure 1 As shown, along the planting transect of emergent plants as the starting side, the side toward the center of the water body is the width side, and the bottom elevation of the water body is used as the benchmark, and the isolation tank unit is expanded downward, and the filler unit is filled in the isolation tank unit, so that The space below the top of the isolation tank forms an aerobic zone, facultative zone and anaerobic zone in turn, so that different emergent plants are separated by the isolation tank unit, preventing plant species with strong ecological encroachment from engulfing other plants through their roots.

[0047] When the emergent plants are of shallow root type, the width of the isolation groove unit is 30cm, the depth is 40cm, and the length is set according to the partition length of different emergent plants.

[0048] The packing unit includes from bottom to top: a bottom packing layer, a non-woven ...

Embodiment 2

[0053] Simple deep root type

[0054] Such as figure 2 As shown, when the emergent plants are deep root type, the width side of the isolation tank unit is set to 50cm, the depth is set to 100cm, and the length is set according to the partition length of different emergent plants;

[0055] The packing unit includes from bottom to top: a bottom packing layer, a non-woven fabric layer at the filler boundary as a filler boundary, a surface packing layer, and an isolation non-woven fabric layer arranged at the surface layer on the inner upper part of the surface packing layer.

[0056] The bottom packing layer is formed by laying crushed stones and gravels with a particle size of 2-4cm and a porosity of 35-45% to a thickness of 40cm;

[0057] The non-woven fabric layer at the filler boundary is to cover the top surface of the entire bottom filler layer after laying the bottom filler layer, and the non-woven fabric specification used for the non-woven fabric layer at the filler bo...

Embodiment 3

[0060] complex shallow root system

[0061] Such as image 3 As shown, when the emergent plants are of shallow root type, the width side of the isolation tank unit is set to 30cm, the depth is set to 40cm, and the length is set according to the partition length of different emergent plants;

[0062] The packing unit includes from bottom to top: a bottom packing layer, a non-woven fabric layer at the filler boundary as a filler boundary, a surface packing layer, and an isolation non-woven fabric layer arranged at the surface layer on the inner upper part of the surface packing layer.

[0063] The bottom packing layer is formed by laying volcanic rock with a particle size of 2-4cm to a thickness of 10cm according to a porosity of 35-45%;

[0064] The non-woven fabric layer at the filler boundary is to cover the top surface of the entire bottom filler layer after laying the bottom filler layer, and the non-woven fabric specification used for the non-woven fabric layer at the fil...

Abstract

The invention discloses an environment-friendly root isolation system with a biological purification function. An isolation groove unit is downwards excavated in an expanding manner by taking the elevation of the bottom of a water body as a reference along a planting sample line of an emergent aquatic plant as a starting edge and one side towards the center of the water body as a width edge, and is filled with a filler unit; and an aerobic zone, a facultative zone and an anaerobic zone are sequentially formed in a downward space at the top of the isolation groove. Plants are separated through the isolation groove units, so that plants with strong ecological invasion ability are prevented from invading other plants through roots.

Description

technical field [0001] The invention relates to the technical field of ecological restoration engineering. More specifically, the present invention relates to an environment-friendly root partition system with biological purification function. Background technique [0002] With the continuous development of social economy, various water pollution problems such as black and odorous water bodies and eutrophication of water quality are becoming more and more serious, gradually threatening people's normal production activities and quality of life, and the water environment is the foundation of human survival. In recent years, with the release of relevant environmental restoration and governance policies such as the "Water Pollution Prevention and Control Action Plan", environmental pollution governance and ecosystem restoration have become the focus of domestic attention. [0003] Aquatic plants are an important part of river and lake ecosystems and have significant ecological ...
