Novel isolating and retaining structure with purification function and rapid construction method

Abstract

The invention provides a novel isolating and retaining structure with a purification function and a rapid construction method thereof. Two rows of fixing holes are drilled in the positions with good stability in a roadway, a filter layer and a supporting layer are sequentially connected with the periphery of the roadway through fixing structures, long-strip-shaped bags with reserved long pipes andmade of non-woven geotechnical cloth are arranged in the middles of the filter layer and the supporting layer in advance, one long-strip-shaped bags is horizontally arranged at each of the top and bottom of the roadway, and the other long-strip-shaped bags are vertically hung on the fixing structure or a metal net of the filter layer; purification materials are sequentially poured into the long-strip-shaped bags from openings of the long pipes through a grouting machine, a filled space is coordinately compacted by adjusting the long-strip-shaped bag at the bottom and the long-strip-shaped bagat the top, and it is guaranteed that no gap exists; and the content of pollutant components in seepage water is periodically checked, and the purification materials are replaced when the content exceeds an allowable value. According to the technical scheme, the novel isolating and retaining structure has the advantages of being easy to construct, short in construction period, good in water filtering performance, flexible in supporting and the like, heavy metal pollution brought out by the seepage water of a filled stope can be effectively purified, so that mines and the surrounding water environment are protected.

Description

technical field [0001] The invention discloses a novel purification barrier structure and a rapid construction method, which are especially suitable for underground filling mines where underground water develops and fillings contain harmful pollution sources. Background technique [0002] In the fill and fill mining method, the construction of the barrier wall is an essential process. Traditional retaining walls are generally gravity retaining walls, such as brick, concrete, steel-concrete and so on. This kind of retaining wall construction method requires a lot of work, takes a long time, and is prone to local deformation, cracking and even collapse. When the thickness of this kind of retaining wall is large, the water filtration effect is poor, which will easily lead to low early strength of the filling body and fail to achieve the expected supporting effect. In underground filling mines where the groundwater is developed and the fillings contain harmful pollution source...
