FOR Road Tunnel Formwork System

Steel Formwork Tunnel Lining Trolley

Designed and developed by our own company, hydraulic tunnel lining trolley is an ideal system for formwork lining of railway and highway tunnels. Driven by electrical motors, it is able to move and walk by itself, with hydraulic cylinder and screw jack being used to position and retrieve the formwork. The trolley has many advantages in operation, such as low cost, reliable structure, convenient operation, fast lining speed and good tunnel surface.
The trolley is generally designed as a steel arch type, using a standard combined steel template, without automatic walking, using external power to drag, and the detachment template is all manually operated, which is labor-intensive. This type of lining trolley is generally used for short tunnel construction, especially for tunnel concrete lining construction with complex plane and space geometry, frequent process conversion, and strict process requirements. Its advantages are more obvious. The second tunnel reinforced concrete lining adopts a simple arch frame design, which solves these problems well, and at the same time, the engineering cost is low. Most of the simple trolleys use artificial concrete pouring, and the simple lining trolley is filled with concrete conveying pump trucks, so the rigidity of the trolley should be particularly strengthened. Some simple lining trolleys also use integral Steel Formwork, but they still use threaded rods and do not move automatically. This type of trolley is generally filled with concrete delivery pump trucks. Simple lining trolleys generally use combined steel formwork. Combined steel formwork is generally made of thin plates.

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.
