Abstract

The invention provides a tunnel lining trolley, and relates to the technical field of tunnel lining construction. The tunnel lining trolley comprises a lifting section template and a fixed template; the lifting section template is in a crescent shape, and the arc surface of the lifting section template can fit with a tunnel outline; and the lifting section template is fastened to a top die of thefixed template, and the lifting section template is detachable and fixedly connected with the fixed template. Because of the crescent shape of the lifting section template, the lifting section template is only necessary to fasten on the top die during construction, the assembling time of construction personnel can be shortened, and the stability of the tunnel lining trolley is further improved; and at the same time, shortening the assembling time further improves the safety of the construction. In addition, because the lifting section template is in a crescent shape and the arc surface can fitwith the tunnel outline, the tunnel lining trolley can fit the tunnel outline more during concrete lining construction, the lining construction effect is improved, and the appearance quality is ensured.

Description

technical field [0001] The invention relates to the technical field of tunnel lining construction, in particular to a tunnel lining trolley. Background technique [0002] The tunnel lining trolley is special equipment that must be used in the secondary lining of the tunnel construction process, and is used for the concrete lining construction of the inner wall of the tunnel. Tunnel lining trolley is an indispensable non-standard product for secondary lining during tunnel construction, mainly including simple lining trolley, fully hydraulic automatic walking lining trolley and grid-type lining trolley. [0003] At present, the number of newly built expressways in mountainous areas is increasing, and the number of extra-long tunnels is increasing day by day. Often in the process of tunnel construction, especially in the construction of long tunnels, there are many cross-section changes. In the prior art, the elevated section of the air vent is assembled by "section steel + s...
