Detachable and usable roadway filling retaining wall and construction method thereof

Abstract

The invention relates to a detachable and usable filling retaining wall and a construction method thereof, and belongs to the technical field of underground mine filling and plugging. According to the technical scheme, the detachable and usable filling retaining wall comprises single hydraulic props, a bottom plate bearing plate (3), a top plate bearing plate (4), metal formworks (5) and filter cloth or geotechnical cloth (6), the single hydraulic props comprise upper props (1) and lower props (2) which are connected together, the single hydraulic props are arranged in a roadway at certain intervals, the upper ends of the upper props (1) and the lower ends of the lower props (2) in the single hydraulic props are fixed to the top plate bearing plate (4) and the bottom plate bearing plate (3) respectively, a metal formwork (5) is arranged between every two adjacent single hydraulic props, and the filter cloth or geotechnical cloth (6) is flatly laid on the metal formworks (5). The detachable and usable filling retaining wall has the beneficial effects of being simple in structure, rapid and convenient to construct, safe, reliable, few in material, capable of being disassembled and reused, small in engineering amount and investment and capable of meeting the underground filling requirement.

Description

technical field [0001] The invention relates to a detachable and usable roadway filling retaining wall and a construction method thereof, belonging to the technical field of underground mine filling and sealing. Background technique [0002] At present, in order to protect the ecological environment in domestic mines, the filling mining method is the first choice for underground mining. The filling slurry prepared at the surface filling station is sent to the underground empty area by gravity or pumping. In order to ensure that the entire goaf is separated from the lower production shaft, it is necessary to build a filling retaining wall in the lower roadway of the goaf. Considering the pressure, airtightness and water filtration of the retaining wall, the conventional filling mine adopts reinforced concrete and hollow brick retaining wall structure. Although the sealing effect is achieved, there are problems such as high labor intensity, long construction period, many mate...

AI Technical Summary

Problems solved by technology

Considering the pressure, airtightness and water filtration of the retaining wall, the conventional filling mine adopts reinforced concrete and hollow brick retaining wall structure. Although the sealing effect is achieved, there are problems such as high labor intensity, long construction period, many materials and high one-time consumption. Therefore, there are It is necessary to innovate and design a construction method of filling retaining wall that can be dismantled and utilized
