Description

Technical Field

[0001] This invention relates to the field of sealing abandoned pyrite mine shafts, and more specifically to a sealing device for abandoned pyrite mine shafts. Background Technology

[0002] The long-term mining of pyrite in my country has resulted in a large number of abandoned pyrite mines. The sulfides remaining in these abandoned mines produce large amounts of acidic wastewater containing heavy metals through oxidation by air, leaching by rainwater, and microbial oxidation, which seriously damages the ecological environment.

[0003] Furthermore, the sleeve valve grouting method was independently developed by the French foundation construction company Soletanche in the 1950s. It was first proposed to ensure the uniform modification of the grouting soil. The sleeve valve grouting process can simultaneously meet the dual requirements of mine water stoppage and mine reinforcement in the treatment of acidic water in pyrite mines.

[0004] Furthermore, after sealing the abandoned pyrite mine shaft with sleeve valve pipe, during the gradual grouting process, it is necessary to use lifting equipment to pull out the core pipe.

[0005] Therefore, those skilled in the art have provided a device for sealing abandoned pyrite mine pits to solve the problems mentioned in the background art. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides a device for sealing abandoned pyrite mine shafts. The device includes a sleeve valve pipe and a grouting device, as well as a pipe body removal auxiliary assembly. The pipe body removal auxiliary assembly includes a fixing ring, a sleeve is slidably connected inside the fixing ring, a pipe body fixing assembly is connected inside the sleeve, a lifting drive assembly and a lifting connection assembly are connected to the upper end of the fixing ring, the lifting drive assembly is sleeved on the outside of the sleeve, the lifting connection assembly is connected between the sleeve and the fixing ring, and an equipment fixing assembly is connected to the outside of the fixing ring. The lifting drive assembly includes a drive motor connected to the upper end of the fixed ring. A drive gear is fixedly sleeved on the outer side of the output shaft of the drive motor. A limiting ring groove is connected to the upper end of the fixed ring. A rotating arc plate is slidably connected inside the limiting ring groove. A driven gear is connected to the upper end of the rotating arc plate. The drive gear and the driven gear are meshed together. The lifting connection assembly includes a lifting limiting cylinder connected to the upper end of the fixed ring. A lifting limiting component is connected to the upper end of the sleeve. Multiple sets of lifting limiting components are evenly spaced between the fixed ring and the sleeve. The end of the lifting limiting component away from the sleeve is slidably connected inside the lifting limiting cylinder. An external thread is connected to the outer side of the sleeve. An internal thread is connected to the inner wall of the driven gear. The internal thread and the external thread are meshed together.

[0007] Preferably, the tube fixing assembly includes a hydraulic push rod, which is connected inside the sleeve, and a fixed arc plate is connected to the telescopic end of the hydraulic push rod.

[0008] Preferably, the tube fixing assembly is provided with multiple sets at equal intervals inside the sleeve, and the side of the fixing arc plate away from the hydraulic push rod is connected with anti-slip particles.

[0010] Preferably, the device fixing assembly has multiple sets of mounting holes at equal intervals on the outer side of the fixing plate, and each set of mounting holes is connected to a fixing cone.

[0011] Preferably, the sleeve valve pipe in this scheme is made of φ38mm PE pipe, laid in two paths in a double helix orthogonal structure with a pitch of 4m, spiraling forward around the surrounding rock of the mine, and connected at the intersection with cross connectors.

[0012] The technical effects and advantages of this invention are as follows: When in use, this invention uses an auxiliary component for removing the core tube, which facilitates the removal of the core tube, saving time and effort and improving the applicability of the overall equipment. Furthermore, this solution uses a sleeve valve tube to inject grout evenly, at multiple points, and quantitatively in the mine, ultimately forming a uniformly distributed solidified body in the mine and the surrounding fractured and fissured zones, thus increasing stability.
