Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel engineering, and in particular relates to a construction device for single-layer lining of a tunnel. Background Art

[0002] From the practical experience of railway and highway tunnel projects at home and abroad, with the development of economy and society, on the one hand, cross-river and cross-sea tunnel projects are increasing, and it is difficult to avoid unfavorable construction conditions such as tunnels being located in pressurized water strata and passing through complex karst and uneven soft and hard strata; on the other hand, modern transportation methods have put forward higher requirements on the durability of tunnels such as crack resistance and anti-seepage. Traditional single-layer and double-layer lining structures of tunnels are difficult to meet the needs of modern tunnel engineering construction under complex hydrological and geological conditions.

[0003] According to the people-oriented construction concept and considering the whole life cycle cost, more and more tunnel projects under complex hydrological and geological conditions adopt single-layer lining structure. At present, due to the annular shape of the tunnel, the inner wall of the tunnel is unprotected during the single-layer lining construction, which may cause potential danger to personnel. Therefore, we propose a construction device for single-layer lining of tunnels. Utility Model Content
