Abstract

The invention discloses a recyclable steel structure filled retaining wall which comprises a composite wall formed by overlaying a plurality of wall fixing round steel bars, an I-shaped steel structural wall, a mesh and water filtering cloth together in sequence, wherein the composite wall is mounted between a goaf and a roadway; I-shaped steel supports and a plurality of supporting and fixing round steel bars are arranged on the back surface of the composite wall for fixation; the composite wall fixing round steel bars are arranged on the periphery of the composite wall at intervals; the tail ends of the composite wall fixing round steel bars are anchored into surrounding rocks to be fixed; the supporting and fixing round steel bars are anchored into the bottom of the roadway; shotcrete is arranged between the composite wall and the roadway. The recyclable steel structure filled retaining wall is novel and reasonable structural design, convenient to construct, high in supporting strength, high in safety performance, good in sand blocking and water filtering effects, capable of being detached and reused, and low in comprehensive cost.

Description

Technical field: [0001] The invention relates to a goaf filling technology in underground mineral mining, in particular to a recyclable steel structure filling retaining wall. Background technique: [0002] The advantages of the filling method are strong adaptability, high ore recovery rate, low dilution rate, safer operation, full use of tailings, reduction of waste discharge, and protection of the surface environment. Setting the filling retaining wall is a very important work before filling the goaf. The filling retaining wall has two main functions: first, it plays a role of sealing and isolating the goaf to prevent the filling tail mortar from overflowing; second, it filters The water function and the water filtration effect will directly affect the maintenance time and quality of the filling body in the later stage. With the continuous development of mining technology, the proportion of the application of filling method in domestic mining is increasing day by day, and...
