【Abstract】In this paper, the Guangzhou Metro Line twenty-one project No.13 Jinkeng station to Zhenlong south station secondary lining of the tunnel construction as an example, this paper introduces a new type trackless type hydraulic tunnel lining trolley in the design and application of the construction of the secondary lining of the tunnel. The engineering practice shows that the new type rail tunnel lining trolley hydraulic tunnel lining construction can meet the normal tunneling operation, and avoid the tedious process of laying the track in the process of the the secondary lining of the tunnel, the construction is more efficient, and the quality is better, and reduces the labor intensity of the workers, a good solution the construction process of traditional tunnel and existing laying the track, hydraulic trolley is easy to move. Reduce the expenses of labour,its economic efficiency has greatly improved.
【Key words】A non-rail tunnel;Secondary lining of the tunnel;Lining hydraulic trolley
