Embodiment 1

[0028] Example 1, such as figure 1 As shown, a construction method for in-situ matrix improvement and vegetation restoration in acidic heavy metal mines, when in-situ restoration construction on slopes, the construction process includes the following steps:

[0029] S1. According to the design and construction drawings and the field conditions of the mine landform, the construction party will conduct sampling and analysis on the mine soil quality of each block. For each area with different acidity from the appearance of the mine landform on site, arrange manual collection of samples at least 5 times, and collect at least 100 soil physical and chemical samples and 100 microbial samples each time.

[0030] Intensive sampling of the soil in the entire area is carried out, and every 100 square meters is arranged manually to collect samples at least once before construction and after construction, and at least 3 soil physical and chemical samples and 3 microbial samples are collect...

Embodiment 2

[0053] Example 2, such as figure 2 As shown, a construction method for in-situ substrate improvement and vegetation restoration in acidic heavy metal mines, when repairing and constructing in-situ on the cantilever surface, the construction process includes the following steps:

[0054] S1. According to the design and construction drawings and the field conditions of the mine landform, the construction party will conduct sampling and analysis on the mine soil quality of each block. For each area with different acidity from the appearance of the mine landform on site, arrange manual collection of samples at least 5 times, and collect at least 100 soil physical and chemical samples and 100 microbial samples each time.

[0055] S2. According to the results of slag sampling and testing before construction, the technicians confirmed that the acidic soil modifier, the acidic soil special microbial inhibitory bacteria group, and the nutrient were mixed with water to obtain the modif...

Embodiment 3

[0075] Embodiment 3, a construction method for in-situ substrate improvement and vegetation restoration in acidic heavy metal mines, when the platform type regreening restoration construction, the construction process includes the following steps:

[0076] Firstly, the site should be leveled according to the original construction design drawing of platform-type regreening, and the soil layer with a depth of about 100-500cm should be plowed to level the site, and slope protection and drainage measures should be taken.

[0077] Then, the construction technology basically carries out construction according to the step of embodiment 1. To put it simply: artificially spread the acidic soil modifier, microbial acid-inhibiting bacteria and nutrients, and mix them evenly with the surface soil, and then artificially spread the substrate-improving comprehensive bacterial agents, nutrients and organic fertilizers and mix them evenly with the substrate , and finally artificially sow seeds...

Abstract

The invention relates to an acid heavy metal mine in-situ matrix improved vegetation recovery construction method. The construction method comprises the following steps: performing sampling, testing and analyzing on acid soil, improving the acid soil, improving the mine soil in-situ matrix, and performing sowing of seeds, a microbial agent, a nutritional agent and plant soil, and taking plant growth protection measures, thereby protecting diversified development of vegetation. According to the construction method, through ordered construction steps and processes, the problem of mountain acid production is solved from the source, and the problems of acidity, heavy metal mines, soil pollution ecological restoration and the like can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of mountain vegetation restoration, in particular to a construction method for in-situ matrix improvement vegetation restoration in acidic heavy metal mines. Background technique [0002] For the restoration of mountain vegetation on acid pyrite mines, the existing technologies use physical methods to cover soil and make clay isolation layers to provide a plant growth environment, but none of them solve the problem of acid production from the source, and there are rapid degradation of plants after short-term growth and soil Acid reflux phenomenon. Due to the particularity of the ecological restoration of acid mines, each construction process step must be tested and confirmed by a special person in time to confirm the treatment effect. The construction materials must be strictly proportioned according to the test results. The materials themselves must be finely processed, and the construction steps and proces...
