Embodiment 1

[0090] This embodiment 1 provides a construction method of a coal gangue rebuilding project, which includes the following steps:

[0091] Step 1. Make an ecological bag 30, which includes a bag body and water-retaining soil filled in the bag body;

[0092] Step 2. According to the actual topography of the accumulated coal gangue 10, the ecological bag 30 is layered layer by layer from bottom to top on the surface of the accumulated coal gangue 10, so that a layered layer from bottom to top is formed on the surface of the accumulated coal gangue 10 Several fixed layers 20, each fixed layer 20 includes a plurality of ecological bags 30 arranged in sequence in a direction surrounding the piled coal gangue 10;

[0093] Step 3. Use a fixed gripper 40 to fix the eco-bags 30 in adjacent fixed layers 20 together, thereby connecting the plurality of fixed layers 20 together;

[0094] Step 4. An opening is formed on the surface of the ecological bag 30, a woody plant 50 is planted in the openin...

Embodiment 2

[0108] This embodiment 2 provides a construction method of a coal gangue re-greening project. Compared with the above embodiment 1, the difference is that: the mass percentage of the water-retaining agent in the water-retaining soil is 6%, and the surface of the bag body The porosity is 28%; the woody plant 50 is crape myrtle; the fine soil 60 is a clay soil with a particle size between 2 mm and 3 mm.

Embodiment 3

[0110] This embodiment 3 provides a construction structure of a coal gangue re-greening project, which is obtained by using the construction method of the coal gangue re-greening project described in embodiment 1.

Abstract

The invention provides a construction method and construction structure for a stacked gangue reforestation project. The construction method for the stacked gangue reforestation project comprises the steps that the surface of stacked gangue is provided with a plurality of fixing layers stacked one by one from bottom to top; each fixing layer comprises a plurality of ecologic bags sequentially arranged around the stacked gangue, the multiple fixing layers are fixed together through fixing grippers, woody plants are planted inside the ecologic bags, the ecologic bags are filled with fine soil, and grass seeds are sown on the surfaces of the ecologic bags and the fine soil. Water retention soil located inside the ecologic bags and the fine soil located outside the ecologic bags supply growth soil for woody plants and herbaceous plants, finally, fixation on the stacked gangue structure and greening of the surface of the stacked gangue are achieved by means of the woody plants and the herbaceous plants, and ecologic repair is achieved.

Description

Technical field [0001] The invention relates to the technical field of ecological restoration, and in particular to a construction method and construction structure of a coal gangue restoration project. Background technique [0002] my country is a big country in the production and use of coal, and coal mining has caused a large accumulation of coal gangue. A large amount of coal gangue is piled up on the ground for a long time, causing serious ecological problems. The specific manifestations are: the accumulated coal gangue has poor structure, stability and porosity, and is easy to raise dust, collapse, heat and explode; coal gangue itself has low fertility, water and fertilizer retention capacity, and lacks the nutrients required for vegetation growth, resulting in no grass; especially Coal gangue contains a large number of pollutants such as heavy metals, and migration in the ecosystem poses a great risk to the soil environment, causing air pollution, water pollution, and far...
