Tunnel support structure
2006
The present invention discloses a supporting structure tunnel, intended to provide a load carrying capacity can not only improve the overall support structure, and simple construction process and has good maintainability of the tunnel support structures. Comprising: a supporting initial shotcrete, in combination with the tunnel rock; B building secondary lining concrete layer mold, in combination with the inner wall of the initial layer of shotcrete support, the secondary lining concrete layer mold building. there is also provided on the inner wall of the waterproof layer; said mounting member by a waterproof layer is provided on the inner wall from the wall of the secondary lining concrete building mold layer. Overall carrying capacity of the tunnel support structures of the present invention enhance simple construction process, reducing tunnel construction costs; and has good maintainability, and does not have an impact on the carrying structure, easy to operate, which can effectively ensure the overall durability of the tunnel structure design life of reach.
