Full Length Corrugations & Lapped Joints for More Effective Stiffness & Ring Compression. The Liner Plate provides optimum shaft stability and protection when constructing new utility tunnels, relining structures under highways and railroads and lining vertical shafts.
Tunnel liners are one of the most versatile segmental corrugated steel panel systems on the market today. Designed for laying soft ground tunnels and re-lining existing pipes under roads and railroads, their application extends to caissons, vertical shafts, mine entrances, etc. They are installed immediately after the tunnel boring machine is in operation. They are designed to resist earth pressure and groundwater head and to provide a framework for the end use of the tunnel.
They are quick and easy to install and cause minimal disturbance to road users and the surrounding environment as they do not require complex tunnel lining equipment. A variety of material options and coatings are available to optimize service life requirements.
The minimum allowable depth of cover is the largest of:
For roads H=B/8+0.2(m) H=B/6(m) and not less than 0.6（m）
For railways H=B/4 and not less than 0.6(m)
There is a possibility to reduce depth of cover provided that suitable checking calculations will be made.
|Flexible structure||Plate thickness||Kinds of standard corrosion protection||Required average min value(um）|
|plates||≧6mm||Hot zinc galvanizing||85|
|≧3mm do < 6mm||Hot zinc galvanizing||70|
|≧1.5mm do < 3mm||Hot zinc galvanizing||55|
|Bolts and nuts||-||Hot zinc galvanizing||45|
Economy of construction time, excavation, materials and manpower.
Maximum support for each given length, minimum weight of steel.
Variations in slab design criteria for various tunnel shapes in dry or wet ground.
Predictable strength, fire resistance.
Continuous support for the critical mining phase of soft ground tunneling.
Easy to store, handle and erect, whether the tunnel is straight, curved, round, oval or horseshoe shaped.
Gasket plates that seal joints to prevent leaks and reduce air loss if water becomes a problem.
