Primary lining system utilizing waste pile foundation and effectively reducing land subsidence

The utility model relates to the technical field of lining of tunnels, footrills or other underground caverns, and discloses a one-time lining system which utilizes waste pile foundations and effectively reduces ground subsidence, and the one-time lining system is used for underground excavation of underground caverns which interfere with waste piles in stratums. According to different positions of the waste piles, the waste piles and a part of lining grids are fused into a whole to form an annular structure for supporting the underground cavern, under the holding and wrapping of the pile holding barrel and the supporting of the primary lining, it is guaranteed that the ground at the positions of the waste piles does not settle, and the lining at the position interfered by the waste piles can also form a ring to resist stratum pressure. And meanwhile, a part of waste piles are used as a part of the primary lining, so that the use amount of construction materials is reduced. 本实用新型涉及隧道、平硐或其他地下洞室的衬砌技术领域，公开了一种利用废
