Problems solved by technology

Due to the improper construction of the retaining wall in some mines, problems such as slurry running and sand leakage often occurred during the filling process, and serious accidents such as the overall collapse of the retaining wall occurred, resulting in underground environmental pollution and difficulties in handling sand leakage.
In order to improve the safety of the filling retaining wall, some mines increase the thickness of the retaining wall, resulting in increased consumption of filling materials and longer construction time, which in turn leads to low efficiency of mining and filling operations.

Abstract

The invention discloses a construction method of a reinforced concrete airtight wall and an application of the construction method. The construction method comprises the following steps of mould hole punching and erecting, rib hole placing, rib distributing, formwork erecting, drainage pipe mounting, cement brick wall laying, slurry plastering, wall bracing arranging and the like. The construction method can be used for construction of an airtight wall when a goaf is filled through a downward horizontal layered road approaching type cementing filling mining method. Raw materials for constructing the airtight wall are common building materials, special machining is not needed, the construction process is simple, the professional skill requirement for constructors is not high, operability is high, the using materials are transported to a site, construction of the airtight wall (not comprising hollow brick building top sealing) can be completed through 2 workers within 8 hours, and the problems that currently, when an airtight wall is constructed, labor and time are wasted, safety and reliability are poor, the economic cost is high, and spread of sudden accidents cannot be quickly and effectively restrained are solved.

Description

technical field [0001] The invention relates to the technical field of mine safety construction, in particular to a construction method and application of a reinforced concrete airtight wall. Background technique [0002] Due to the advantages of safe operation, small ore loss, delay or even prevention of engineering geological disasters such as surface subsidence and deep rockburst, filling mining method is more and more used in actual mine production. In the filling mining process, the construction of the filling retaining wall is an important preparatory work that must be completed before filling. The construction quality of filling retaining wall directly affects the efficiency, cost and filling quality of filling operation. Due to improper construction of the retaining wall in some mines, problems such as slurry running and sand leakage often occurred during the filling process, and serious accidents such as the overall collapse of the retaining wall occurred, resultin...
