Hydraulic Mobile Tunnel Concrete Forms

Tunnel concrete forms are used to pour concrete liner after tunnel is excavated. It is widely used in civil tunneling and water work projects.


The forms are designed and made according to tunnel section specifications provided by clients. Hydraulic stations are used to power the hydraulic cylinders to thrust or withdraw the form pieces.

Heavy labor work is minimized. Mobile mechanism is used to move forms along track. It  greatly increases the productivity and quality of the tunneling concrete liner work. Leedem supplies three types of tunnel concrete forms:

Girder Truss Type

Door Frame Type

Shutter Type

Leedem has successfully designed and supplied a shutter type concrete form to Australia mining company McConnell Dowell’s Philippine Ambulklao Dam Project. The following pictures demonstrates the concrete form being in use and tunnel after finished. More detail about this project click here.
