Immersion net type ecological slope protection structure for mine restoration and spray seeding construction method thereof

Abstract

An immersion net type ecological slope protection structure for mine restoration comprises a rubble slope layer, the surface of the rubble slope layer is provided with strip-shaped grooves, and firstdrilled holes are formed in the strip-shaped grooves; main anchor rods are inserted into the first drilled holes; the surface of the rubble slope layer is further provided with second drilled holes, and auxiliary anchor rods are inserted into the second drilled holes; the ends, away from the second drilled holes and the first drilled holes, of the auxiliary anchor rods and the main anchor rods areprovided with an iron gauze, and the iron gauze is connected with the auxiliary anchor rods and the main anchor rods in a matched mode; and the position between the iron gauze and the rubble slope layer as well as the top surface of the iron gauze are covered with a base stock layer, and the surface of the base stock layer is provided with a planting layer. According to the immersion net type ecological slope protection structure, overall integrated planning is performed systematically and comprehensively based on the restoration ecology theory, the slope is subjected to processing and reinforcing, the whole stability of the slope is improved, meanwhile, the base stock layer is arranged, the surface of the base stock layer is planted with green plants, thus, the mine landscape is effectively perfected, and the ecological environment is built.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a net-immersed ecological slope protection structure for mine restoration and a spraying construction method thereof. Background technique [0002] The exposed rock slopes are generally formed by the destruction of natural mountains during human activities such as engineering development and construction or natural disasters such as landslides and collapses. According to the different factors of formation, it is generally manifested as the mining pit mouth of the quarry, the closed pit mouth, the waste gas pit mouth, the left slope and the mining gap of the road and railway. The exposed rocky slopes have the following characteristics: first, the surface of the slope lacks soil, moisture and organic matter, the degree of water and soil loss is serious, and it is extremely difficult to restore vegetation under natural conditions; ; Third, a large area of...

AI Technical Summary

Problems solved by technology

[0003] Traditional slope protection measures such as shotcrete anchors, grouted rubble skeletons, cement skeletons, retaining walls, etc., can effectively ensure the stability of slopes, but they are poorly coordinated with the surrounding landscape and cannot meet the needs of modern urban landscapes and people's pursuit of comfortable living. Environmental requirements, and at the same time, there is no comprehensive overall planning based on the theory of restoration ecology in a systematic and comprehensive manner.
