Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] refer to figure 1 , a detachable repairable tunnel lining structure of the present invention, including an arch wall initial support structure 10, a waterproof and drainage system 20 and a lining structure arranged from outside to inside. The lining structure includes the secondary lining 30 of the arch, the frame support structure 40 of the side wall, the filling wall 31, and the pile-slab structure at the bottom of the tunnel. The frame structure is used as the bearing structure of the secondary lining of the arch to replace the secondary lining of the side wall The molded concrete for the secondary lining can not only save concrete, but also facilitate the drainage of groundwater behind the side wall.
[0018] refer to figure 1 The pile-slab structure at the bottom of the tunnel includes a bottom plate 32 laid on the base sealing layer 11 , ...
