Variable-direction guide rail type supporting structure capable of resisting three-dimensional movement deformation

Abstract

The invention discloses a variable-direction guide rail type supporting structure capable of resisting three-dimensional movement deformation. The variable-direction guide rail type supporting structure comprises a U-shaped joist, bearing beams and a variable-direction supporting unit capable of resisting three-dimensional movement deformation, the U-shaped joist is additionally arranged on a foundation pillar of a protected building (structure), the U-shaped joist is arranged on the bearing beam, and the bearing beam is in sliding connection with the upper end of the variable-direction supporting unit capable of resisting three-dimensional movement deformation; and when ground movement deformation is caused by underground coal mining, the upper ends of the variable-direction supporting unit capable of resisting three-dimensional deformation freely move along a transverse guide rail on the lower plate faces of the bearing beams. The influence of the dead weight of a coal shed body andthe acting force of the ground surface on the device on the device in the ground surface mining deformation process can be eliminated through adjustment and movement of the posture of the device, thenmechanical damage of the protected building (structure) to ground surface mining deformation is relieved, and therefore moving of the building (structure) in a subsidence area is avoided.

Description

technical field [0001] The invention relates to the technical field of mining area construction. Specifically, it is a variable guide rail support structure that resists three-dimensional movement and deformation. Background technique [0002] The mining of large and medium-sized coal mines usually requires the construction of a coal shed for coal storage and transfer, and the construction site of the coal shed may be located above the coal seam. In this case, when the coal seam in the stratum below the coal shed is mined, the ground will subside Finally, the structure of the coal shed will be affected to a certain extent, such as foundation subsidence, etc. Once the supporting structure of the coal shed is affected, there will be a danger of the coal shed collapsing. In order to avoid mining the coal seam below the existing coal shed When the coal shed collapses, the usual method is to move the coal shed to other areas, such as the backfill area or the ground below without...

[0002] The mining of large and medium-sized coal mines usually requires the construction of a coal shed for coal storage and transfer, and the construction site of the coal shed may be located above the coal seam. In this case, when the coal seam in the strata below the coal shed is mined, the ground will subside Finally, the structure of the coal shed will be affected to a certain extent, such as foundation subsidence, etc. Once the supporting structure of the coal shed is affected, there will be a danger of the coal shed collapsing. When the coal shed collapses, the usual method is to move the coal shed to other areas, such as the backfill area or the ground below without coal, and the demolition and reconstruction require a lot of manpower and material resources, which will increase the production cost of the enterprise

Therefore, when building a coal shed, a support structure that can resist the impact of surface mining deformation is used, or the existing coal shed is transformed with a support structure that can resist the impact of surface mining deformation, while the existing The supporting structure has poor resistance to the influence of surface mining deformation, and stress damage often occurs, which in turn leads to structural damage of the supporting structure, resulting in the collapse of the coal shed
