Concrete Casting Tunnel Formwork For Tunnel Construction

Concrete Tunnel Lining Trolley for Subway

The Subway Tunnel Trolley is a 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. Concrete lining trolley is an indispensable non-standard product for secondary lining during tunnel construction. There are mainly simple lining trolleys, fully hydraulic automatic walking lining trolleys and net-frame lining trolleys. Full hydraulic lining trolley can be divided into side-top arch type, full circle needle beam type, bottom mold needle beam type, full circle travel type and so on.

 The action of the template must be able to effectively complete the mold supporting, mold dismantling, and locking and positioning work. In the template trolley designed in recent years, the support and demolding of the template are hydraulically driven, and the locking is completed by mechanical devices. The overall formwork should be left with operating windows and grouting holes to meet construction requirements. The length of the overall formwork and the wheelbase of the gantry traveling wheels are related to the turning radius of the tunnel and the construction organization of other supporting machinery. The general formwork length is 6m ~ 12m, and the gantry axis distance is less than about 1m of the entire formwork length.

product feature:

* It is widely be used in all kinds of tunnel concrete construction
* The product is easy to use and flexible to disassemble.
* More times turnover, low cost amortization.
* The appearance of concrete is well quality.
* Save labor cost and reduce project cost.

Advantage:

● light weight; 
● simple, strong and stable structure; 
● moved, mounted and stripped easily; 
● strong reusability; 
● small deformation under force; 
● adequate space under traveler and providing a big space for bars and formwork construction operation.
