Variable guide rail support structure resistant to three-dimensional movement and deformation

Abstract

The invention discloses a variable guide rail support structure resistant to three-dimensional movement and deformation. ) on the foundation pillar of the building, the U-shaped support beam is installed on the load-bearing beam, and the load-bearing beam is slidingly connected to the upper end of the variable-direction support unit that resists three-dimensional movement and deformation; when underground coal mining causes ground movement and deformation , the upper end of the variable-direction support unit resistant to three-dimensional movement and deformation moves freely along the transverse guide rail on the lower surface of the load beam. The present invention can eliminate the influence of the self-weight of the main body of the coal shed and the force of the ground on the present invention during the deformation process of the ground mining through the adjustment and movement of its own posture, thereby alleviating the mechanics of the protected buildings (structures) from the deformation of the ground damage, so as to avoid the relocation of buildings (structures) in the subsidence area.

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
