Construction method for landscape bank protection and water bottom seepage prevention of coal mining subsidence land

Abstract

The invention relates to a construction method for landscape bank protection and water bottom seepage prevention of a coal mining subsidence land. The construction method comprises the steps that thelandscape engineering construction site range of the coal mining subsidence land is determined, a probability integral method is adopted for calculating the ground depression value W and the horizontal deformation value epsilon of a construction site, and a deformation area is obtained through division; the critical point for carrying out engineering construction is determined according to the horizontal deformation value; bank protection is carried out on the water side of the bank slope of the coal mining subsidence land, a stone embankment and an ecological embankment are built, and landscape bank protection of the coal mining subsidence land is constructed; and woven textile geotechnical cloth is adopted for splicing and paving, and the water bottom seepage prevention structure of thecoal mining subsidence land is constructed. According to the construction method, the problem that water landscape facilities of the coal mining subsidence land are damaged due to the influence of mining is systematically solved, a good subsidence land ecological restoration effect is guaranteed, and the human settlement around the coal mining subsidence land is improved.

Description

technical field [0001] The invention relates to the technical field of ecological environment control in subsidence areas, in particular to a construction method for landscape revetment and bottom anti-seepage of coal mining subsidence land, and is especially suitable for construction of water body landscape in subsidence land during the moving period due to surface deformation of coal mining. Background technique [0002] The problem of ecological environment management in my country is becoming more and more important. With the land damage caused by coal mining and the area of ​​subsidence areas increasing, the environmental management of mining areas and the utilization of coal mining subsidence areas require continuous innovation and development in technology. According to incomplete statistics, as of At the end of 2017, the land area of ​​the subsidence area caused by coal mining was about 1.7 million hectares, and it was still increasing at a rate of about 40,000 hectare...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to solve the above-mentioned problems in the construction of water conservancy and landscape projects in subsidence areas, and propose a construction method for landscape revetment and bottom anti-seepage in coal mining subsidence areas, so as to be suitable for subsidence areas where the surface deformation is in the moving stage Water body landscape construction aims to solve the problem of damage to water conservancy landscape facilities in coal mining subsidence areas affected by mining, ensure a good ecological restoration effect in subsidence areas, and improve the surrounding human settlements
