Anti - infiltration concrete Tunnel Formwork System with simple structure for channel

The  column tunnel steel formwork system is always used in river way, roads, bridge surface, airport, water and electric station and channel, and it is a kind of concrete laying extension machine for liner building, laying extension and leveling, solid, slurry distilling and leveling of concrete surface. 

The machine can complete laying extension, leveling, slurry distilling, shaking and pounding, rolling, feather drawing, block cutting and maintenance simultaneously. Through replacing components (or purchase), arrange and roll the basic liner layer of inclined plane. 

The column tunnel steel formwork system with simple structure, convenient operation and maintenance, safety and reliability, smooth and dense surface, standard section, and good performance of water and sand transmission, anti-infiltration and anti-frozen with long life. It can reach ideal leveling and density for uneven spreading, low collapsing and higher concrete.
