Anti-sedimentation landfill gas collecting vertical shaft for landfill

The invention provides an anti-sedimentation landfill gas collecting vertical shaft for a landfill, which comprises a gas collecting well extending to the bottom surface of the landfill along the longitudinal direction; the drainage pipe extends into the bottom of the gas collecting well from top to bottom, and gravels are filled between the drainage pipe and the gas collecting well; one end of the stabilizing pipe is detachably connected to the end, extending out of the covering face, of the drainage pipe, and the other end of the stabilizing pipe extends into the position below the covering face through bending and correspondingly communicates with the pre-buried gas collecting well connecting pipe; and clay is tamped, and the gas collecting well is sealed through the tamped clay at the wellhead of the gas collecting well. Part of pile settlement deformation stress can be absorbed through gravel energy dissipation, meanwhile, stress is evenly transmitted, and the settlement stress is prevented from damaging
