Problems solved by technology

Although this structure is safe and effective from the perspective of traditional engineering water conservancy, it also destroys the original natural ecosystem of the bank slope and its corresponding functions, causing serious soil erosion on the surrounding surface and consuming a large amount of materials. The other is flexible engineering, which mainly refers to the bank slope of landscape ecology. When determining the reinforcement treatment of the bank slop...

Embodiment 1

[0037] The present embodiment provides a construction method of an ecological restoration system for preventing soil erosion, comprising the following steps:

[0038] (1) Base layer 1: Cut or fill the original terrain of the river bank that needs ecological restoration into a ladder shape, clean and compact the soil surface, and collect surface soil and rocks;

[0039] (2) Waterproof layer 2: Spray continuous and dense quick-setting waterproof paint on the surface of the base layer 1 in the step (1), the thickness of the single-layer spraying is 1.5mm-2.5mm, and there is no interval between spraying once;

[0040] (3) Lower hanging mesh layer 3: use degradable geonet, the mesh side length is 3cm to 5cm, lay on the surface of the waterproof layer 2 in the step (2), and the laying width should be 40cm larger than the outer edge of the construction area;

[0041] (4) Reinforcement layer 4: including reinforcement grid blocks 41 and ecological geotechnical bags 42, the reinforceme...

Abstract

The invention provides an ecological restoration system for preventing water and soil losses and a construction method. The ecological restoration system sequentially comprises a base layer, a waterproof layer, a lower net hanging layer, a reinforcing layer, a soil layer, a covering layer, an upper net hanging layer and a vegetation layer from bottom to top, and the ecological restoration system is in a stepped shape on the whole. According to the ecological restoration system for preventing the water and soil losses and the construction method, the unique layered structure is adopted, the problems that the water and soil losses are brought about by a rigid structure in traditional embankment engineering, construction cost is high and transportation is inconvenient are solved, and a bettersolution is provided for the problem that a flexible structure cannot keep the landscape effect easily for a long time. Meanwhile, a unique engaged and hollowed structure is designed for brickwork ofthe reinforcing layer, embedding of ecological geobags is combined, stability of the embankment structure is guaranteed, the effect of preventing the water and soil losses is achieved and a good growing carrier is provided for plants. In addition, resource utilization of collected surface earth and stone as well as waste like plant roots, stems and leaves, riverway sludge, livestock excrements and industrial dregs in various industries is realized, and economic benefits and social benefits are good.

Description

technical field [0001] The invention relates to the technical field of ecological restoration and environmental protection, in particular to an ecological restoration system and a construction method for preventing water and soil loss. Background technique [0002] At present, there are two mainstream forms of embankment engineering for water-retaining structures built along rivers, channels, lakes, coasts, flood diversion areas, and reclamation areas. One is rigid engineering, which uses concrete, masonry and other materials to replace the original Natural bank slopes, concrete, masonry blocks and other building materials are widely used because these materials have good impact resistance, erosion resistance and durability. At the same time, for artificial canals for water delivery, they can also reduce roughness and improve water delivery efficiency. , to reduce permeation loss. Although this structure is safe and effective from the perspective of traditional engineering ...
