Problems solved by technology

[0004] In summary, the existing problems in the prior art are: (1) the existing rainwater collection system reuse system cannot be applied to the rainwater collection of abandoned mine lands
[0005] (2) The existing landscape reconstruction for mine wasteland is not equipped with corresponding rainwater collection and utilization technology, and the scenic spot needs other water sources
[0006] (3) There is no relevant method for improving the water environment of mine wasteland in the prior art

[0177] 1. Design calculation

[0178] 1.1 Determination of annual total runoff control rate by division

[0179] The existing technology roughly divides the land area into five zones, and the minimum and maximum limits of the total annual runoff control rate α in each zone are: Zone I (85%≤α≤90%), Zone II (80%≤α≤85% %), Zone III (75% ≤ α ≤ 85%), Zone IV (70% ≤ α ≤ 85%), Zone V (60% ≤ α ≤ 85%), all regions should refer to this limit and determine the local conditions according to local conditions. Regional runoff total control target.

[0180] 1.2 Calculation formula of total runoff

[0181] W1 = 10ΨHF.

[0182] In the formula, W1——the total amount of runoff, m 3 ;

[0183] Ψ——rainfall runoff coefficient;

[0184] H——design daily rainfall, mm;

[0185] F——catchment area, hm 2

[0187] Rainwater initial abandonment flow:

[0188] W2=10σF

[0189] In the formula, W2——the initial abandonment flow of rainwater, m 3 ;σ—thi...

Abstract

The invention belongs to the technical field of ecological environment restoration, and discloses a rain water collection and recycling construction method for ecological restoration of a mining wasteland. The construction method comprises the steps that a local runoff volume control objective is determined to calculate rain water collection and recycling parameters, wherein the water pressure, lift and flow parameters are calculated; a construction drawing and construction technical requirements are clearly determined, and water supply and drainage of an engineering site and the environment around the site are surveyed on site; according to the design drawing, on-site verification is conducted; a rain water collection and recycling device is built; after the mining wasteland is subjectedto ecological restoration and landscape remodeling, a new thematic function mode is formed, rain water is collected by using the built rain water collection and recycling device, and the collected rain water is sued for irrigating plants in a landscape remodeling main functional area of the mining wasteland. The construction method is simple and easy to implement, scientific in design, easy to construct, install, transport and maintain, and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a rainwater collection and utilization construction method for ecological restoration of abandoned mine lands. Background technique [0002] At present, due to the fact that mines have made great contributions to the development of industrial civilization in history, but objectively, mining activities have also caused huge damage to the surrounding ecological environment and natural landscape, seriously affecting the ecological system of the area where it is located. Aesthetic flaws are also formed in the landscape. With the development of landscape design, urban planning and other disciplines, the reconstruction of abandoned mine land is also deeply affected by it, and new ideas and strategies are constantly emerging. Many abandoned mines have undergone landscape remodeling after ecological restoration, which not only restores the ecological environme...
